    The system analysis that comes with it is awesome however, I am disappointed I'm give it 3 stars. It doesn't clear any of your cache in system storage I have to go out and manually clean the cache data for each app in settings. Very tedious, time-consuming and frustrating! I have owned quite a few Samsung devices. ONLY Samsung phone (Samsung J3) that I have owned that my storage didn't have cache data show up. Samsung please fix you have disappointed. Would love to hear back on this.

    I used to love this original apps... since the latest Samsung OS update to One IU v2, the looks of the apps is new and better, but my phone is getting easy to be hot... so is it possible in the battery section there is an option to detect is my phone is getting warm and hot? There is no option in th Optimize section too... hope there'll be new update/fix soon.

  3. Gabriel LaPard-avatar

    I just got a new phone and device care was great for a few weeks. All of the sudden it wouldn't let me clear my storage anymore. Now, I have to use programs that didn't come with my phone. It's all just another ploy to get you to use your available space faster so they can sell more phones. Very disappointed with this program.😡

  4. Alien Tongue-avatar

    This app is full of it! Says phone is just fine when it's all kind of messed up. Epic failure! Either it's that or it's the fact the phone is another Samsung premium priced piece of trash. I've gone through 3 galaxies in 4 months and my new tv just bought around Christmas is starting to act odd. Garbage, pure over priced trash.

  5. Osama Alnasery-avatar

    The application is useless without the "clean now" option. Had to uninstall the update. Update: came back to check if they added replacements to the missing features, but they haven't. On top of that, it appears that they use paid reviewers to bump up their rating of the app, shameful and absolutely deceitful, especially for a company of this size that doesn't depend on the app for its livelihood.

    Thanks for removing the option to clean the storage the way how it used to have it before. Cleaning my phone's storage has now become impossible due to the recent update that removed the clean button option for service storage. It got worst! Developer and team please fix this ASAP!!! Update 3/20/20 to fix issue just uninstall all updates to bring back the former style of the app

  7. Michael Langrel-avatar

    I have read several reviews complaining, like I was, about the disappearance of the storage cleaning button. There is an easy fix but you have to probably do this every day, regardless if you turn off auto update. Go to settings, apps, device care, top right 3 dot drop menu, uninstall update...problem solved

  8. Nancy Novo O'Connor-avatar

    There was just an update to this app yesterday which seems to have caused several problems. First, the button to clean or clear storage, which also cleared caches, has completely disappeared. Gone. Secondly, even though I am putting some apps to sleep, it does not seem to be working. I optimize to 100%, and minutes later is down to 98. Not what I've been experiencing the past year-and-a-half. Since this app seems to minimally help with my ridiculous battery drain, please fix!

    After the latest update I can no longer clean up the hard drive on my Galaxy note 10 plus. I went through all the features that I know of, but I can't figure it out. Is there something I'm missing? If not please fix this. Sense this is a app that can not be completely uninstalled, I just uninstalled the update, and now all the features including the ones that disappeared, are back. Hope it continues to work.

    theres a problem with this update,the storage clean now button is missing and the storage doesnt get cleaned. It worked before the update. I uninstalled this update to fix that problem. Being how this isn't an app you can delete,when are you going to fix the storage cleaning option. Perhaps you should partner with ccleaner,they have the best cleaner on the market.

    ●UPDATE TO INFINITY: Google/Android bug, or just buggy app.? { Automatic update is disabled. Application "x" is not in the apps-update-list. Application "x" launches itself to update to infinity. Applications in the apps-update-list end up waiting to infinity for appl. "x" to finish. } The apps in the apps-update-list are not able to update, until I go to the installed apps Tab to find application "x", and cancel the self-launched update. So that the apps in the apps-update-list may update.

    This application was perfect before Android 10 update. Not only can you NOT Clean Now the device yourself, the widget that shows ram usage and storage is no more accurate as I am using my device. There was a comment early that said if it is not broke do not fix it. It applies to this situation. Seems to be a little bit more thorough. Not 100 percent. But it is good enough

  13. Kimberly R.-avatar

    I updated Feb 8 2020 and now (feb 10) my fone constantly needs charged. I have never had a problem with this app. I actually always use it and like it. This has been the only change to my fone. I have checked different settings to make sure something isnt using battery without me knowing. I just charged the fone and had 20% battery use in a very short time. Something is not right.

  14. ErnsWay Always-avatar

    I've always used this app to mainly clean the cache, now the function has been removed and I'm unable to clean out the memory, I would really like to know why it was removed and how I'm meant to clean out the cache now. It's been 1 week since the update and my phone is beginning to slow down, I hope I get a real answer instead of a automated response. I'm not the only person who is unhappy with the change, just read the other reviews, I hope a solution is found soon.

  15. Lucinda Koehn-avatar

    You completely ruined the usefulness of this app when you took away the button to clear excess storage caches. I depend on my phone to do my job. It is necessary to keep my caches cleared out and my storage low so that the apps I use for my work will run quickly and smoothly. I had been running my phone at below 50% of my storage, thanks to using the clean now button on the storage page frequently. Since the last update my storage amount has jumped dramatically. I cannot clear out my caches and it doesn't seem like it is being automatically done when the phone optimizes. All the numbers listed for storage in various locations are the same as when I was running my storage below 50%, yet now I have about a gig more storage used than before with no apparent reason and no way to clear that out. This is slowing down the response time in my work apps and causing me to lose productivity and income. PLEASE do something to solve this problem and let us run our phone devices efficiently again!

    I really love this app of Samsung. It helps me monitor the status of my phone from battery to data usage, but the new update ruined the beauty of this app! The "clean cache" feature in the storage section of Device Care was removed! I often use that feature to clean the storage of my phone and that was really helpful, but you removed it! Please bring back that feature in the next update. It is so helpful to free up space in one click than manually cleaning, so I don't know why you removed it!?

  17. Tracy-avatar

    Just updated this app. It is now garbage. It won't let me clear App cache I storage. Before (like one hour ago), I could tap in storage & then pick the app I wanted to clean... it would open it & show internal storage, battery usage, permissions etc. Now I tap on an app, it makes a check mark & the delete icon (garbage can) shows. That is all. What the hell just happened? Go back to what it was! Why must updates screw everything up? They are SUPPOSED to improve! Feb18th: Now 1 Star!

  18. Stephen Flowers-avatar

    Can't clear Cache anymore. Temporary internet files and other rubbish are going to chew storage up as I can't find any new facility to do this; unless it does it automatically, in which case Samsung should make it clear. Used to be a good one stop shop to manage the rubbish. Samsung are going about it the right way if they want to drive everyone to Apple.

  19. Jack Murphy-avatar

    Every time there's an update it just gets worse and worse with you Samsung. Now in device maintenance under storage it no longer cleans cache! So I have to go into applications, and go into every last one, and go to storage and manually clear the cache from each and every last application?!!!!! That would take a decade, cost billions of dollars, and millions of lives would be lost!!!!!. What the hell is your damage Samsung??? Get your head out of your ass, frickin morons

  20. Dwayne Shults-avatar

    The clean storage button is gone. What in the??? Please fix promptly, as I use this frequently. I don't get it. How do we miss something like this? Never mind. I'm reading that feature was accused of including chinese spyware so it was removed. I like the feature, regardless. Shame. I hope you find a way to fix it.

  21. Nick Sabalos-avatar

    I agree with lot of other reviewers here: this used to be such a simple, yet useful app. A five-star app! Now, in Android 10, and the latest updates to this app, it's become overly "cutesy" and doesn't perform as nearly well or intuitively as in previous versions. In fact, it can't even "see" the eleven large apps I have stored -- and running -- on my SD card. (Used to "see" them every time!) Those 11 apps all still work fine and as before....but Device Care only recognizes them when first installed or updated. Then, as soon as one of those apps is opened, Device Care no longer recognizes it's existence on the SD card any more....even though the app's still there and running just fine.

  22. Keith Johnson-avatar

    The new update has eliminated the cache cleaner and unnecessary file remover. No explanation given. I discovered you can uninstall this update and when run it removed nearly a gig of unwanted data. My phone snuck the update back in by downloading it through galaxy store app. I was successful for now in restoring it. Samsung should explain what is really going on. Rumor is that it contained spyware. For now I think it is just CYA on their part at our expense.

  23. Devargha Ray-avatar

    Once a great app, it has really degraded over time. Firstly, the Clean Up button which used to be present to clear cache has completely dissapeared!! Samsung are you listening? Bring this functionality back to users. Secondly, this seem to drain my battery quite a lot, maybe owing to the possibility that the RAM isn't being managed well. There's room for improvement Samsung, just waiting for an update for this app.

  24. Smile-avatar

    This app is great normally but since the update you have taken away the function to clear the storage memory to free space after somebody has gone and deleted pictures, messages etc. I have deleted lots of things to free up space which i could normally function myself. Even after turning the phone on and off the percentage stays the same. Seems like its not functioning at all. Can you please fix this asap?!

  25. Jordane Lowe-avatar

    Worked great before but then updated and removed functionality. I can no longer delete cache at the press of a button to free up space and the option to see what apps where storing additional data was removed. Edit: After a bit of research I found that the removed Qihoo 360 from the app which apparently had suspicions of spying on users but they provided the functionality that I and many users liked this app for. Samsung needs to implement their own solution.

  26. ProudDeaf Mom-avatar

    What's all this? Everything looks stupid and looks complicated. Never again update this stupid app anymore. Quit changing things so much. Can we go back to the previous update rather than this new so called update? And by the way, it doesn't stop the battery from draining so fast enough. Can you fix everything and go back like it used to be? Thanks.

  27. Susan Smith-avatar

    Everyone I know loved this app. Now no one likes this app anymore. Why in heavens name have you made it to where we can't clean our storage? It's not cool. Plus it messes up the phone more. You can't play games for very long either. I and everyone else Hope's you put it all back the way it was. You are going to lose people. Everyone is talking about deleting this app and finding something else. You should of been proud of the app you had. Please fix the storage back to the way it was. Tysm

  28. Michael Braun-avatar

    Um, what? It will no longer show you how much time it's been since your last full charge in battery usage. But you can GUESS from the two hour block you can highlight on the chart? I want to know screen on time and app usage from the exact minute I was last at 100%. Not this nonsense. Now you can only view those stats for either the entire day, which I was asleep for 8 hours of, or for a two hour block during which times your phone may or may not have been charging. Dumb.

  30. lucid-avatar

    Just updated this. Where on earth has the clean storage button disappeared to in the storage section. This is an absolute disaster It's not possible to uninstall and put the old working version back on . It no longer shows the size of files moved to the external SD by the Storage Booster here either Please fix this with an update now and restore the apps functionality!!

  31. Natalie Sterns-avatar

    I thought it was my phone acting up!!! I just read most of these complaints!! I also would clear storage on the regular and now it just freezes on the screen. So... what they all said!! ***Ummm I just googled it. I don't think its coming back peeps lol. Time to move on. I think McAfee has a good one, I'm being told. Just sayin ✌

  32. Tyrone Maysin-avatar

    For some unknown reason y'all removed the only important function of this app cleaning the cache. This app deserves zero stars because it's practically useless. Times like this show me that you guys don't use or test the products you create. I've seen the reply from the company and it was nonsensical as it didn't explain anything other than that those responsible should be fired or demoted.

  33. L Marcks-avatar

    What happened to cleaning the cache?!?! That has to an important aspect of device care, why did the update remove ANY possible option to do just that? My phone suddenly seems to be running hot and the battery draining more quickly than normal doing the exact same things. Huge flaw, please do something about it. It should be a no-brainer...

  34. pndazza-avatar

    Huge mistake Samdung. You have taken a good app and slaughtered it. No simple graph displaying time since last charge !! And the clear cache functionality. The only thing I would like to know is how well my phone is going since the last charge and the time remaining, especially when you work away from power supplies for employment. It then allows the user to gauge usage .. Please add this functionality back.

  35. Chet Walters-avatar

    If this had an ignore list it would be useful. I have two apps that need to run behind the scenes to work and there is now way to let them do it without nagging me. The supplied. Ignore list is not ignored (doesn't work)

  36. Daniel Macris-avatar

    Review updated on 2/26/2020: This app was 5 star until the recent update. Now it's virtually worthless because it doesn't clean cache and unused data. You have to manually go through the apps and empty their cache to clean your phone up and this takes like 30 minutes. I'm not an app designer, but removing the most useful feature in an app seems either incredibly stupid or greedy. I hope Samsung isn't going Apple on us.

  37. Gilberto Mondaca-avatar

    The main problem is that this is powered with software from Qihoo 360, a Chinese data-mining and antivirus company which has some shady practices. Their software has been alleged to be spyware, as reports indicate their willingness to hand over any data to the Chinese government. And this same company is powering the storage scanner on your device with full access to your data. With the last update it doesn't say "powered by 360" anymore.

  38. Bayside 63-avatar

    Update, took my widget. Optimizer on my screen doesn't work, says within 1 second my phone has been optimized. It's not. So I go to app and it's not cleaning properly. Whatever you did, go back to what you had. The app has been amazing for the last several months I have had it.

  39. Michael Stone-avatar

    Was great but since the update it's now awful. Hate the way the battery now cleans. Telling me my Big Bettery App is using up too much usage. I know that but that doesn't mean i want to shut the App down. Loved this App when i changed my phone last October. Not so much now. Just uninstalled all updates, let's see if it's any better now!...............Much better, i certainly will never update this App again 🙂.......left as 1 star to warn others.

  40. Carl Dyke-avatar

    Don't care for this latest update. Unable to "clean" storage (app storage)without deleting the app you are wanting to clean. But, as usual, Samsung doesn't care what the end user finds clumsy, awkward or nuisance. Samsung wants your money, after they get it, they're done with you.

  41. Vedant Damhar-avatar

    I used to be able to clear the junk files that would accumulate on my Galaxy S9. After the new update, the button that you would click to clear the "unnecessary data" just disappeared, and now, I'm not able to delete those junk files anymore. Please return this feature in the next update.

  42. Aaron Phillips-avatar

    Your personal information is being sent to a 3rd party company by this app. Information it DOES NOT require to make this app work. You do NOT have the option to not have your information sent to them either. This app cannot be uninstalled without rooting your phone. And by uninstalling it you will lose access to your phone, access this app provides. Damned if you do and damned if you dont.

  43. B.J. Todd-avatar

    POOR!!! WAS EXCELLENT BUT UPDATE RUINED IT! The app was working 100% before the update ruined the option of clearing the cache etc. Now it only does roughly 45% of the job that the app used too! Please fix this bug asap!!! In meantime I am going to research other apps and if this bug is fixed I'll continue business here , but if this is going to be a permanent issue the I have no choice but to move on ... Hopefully this will be resolved,If possible would appreciate somefeedback on this issue

  44. Jeff Rivers-avatar

    After update to One UI 2.0 Android 10, the battery usage page becomes totally useless, no one really understands the charts. So many Samsung users complain about it all around the web. Nothing changes even after this update. I sincerely hope you can take back the old design which used for a long time & is proved to be a very good design. Though I understand you remove some features from a China spyware company, can you write some codes on you own to bring it back ?

  45. sav vy-avatar

    The latest update ruined the app!!! I am no longer able to clear space, by eliminating junk stored in storage!! I had to uninstall updates!! Please fix the connection to the Chinese company but allow the storage update and cleaning option please??! I AM LIVID!! I have a brand new cellphone with one of the most important apps that is not working properly. Thanks alot!! 😡

  46. Trey Wright-avatar

    OMG!! What have u all done to this app!? It's now literally JUNK!! Good 4 nothing more than a screensaver.. Time & time again the updates for several of these apps are taking away the best features.. and in many cases... the feature that is the main purpose of the app. I've always been a huge Samsung supporter, but the past couple years I feel Samsung developers are pushing it's supporters towards APPLE....and it's working as I do believe this will be my last Samsung✌

  47. Ugo Obinwanne-avatar

    Device care used to be simple and easy to use with Android 9. Now, the battery section is so complicated and you can't see your screen on time after each full charge rather you get the screen on time since midnight. It's no longer very useful. Kindly bring back the feature that allows you to see screen on time since last full charge.

    Dear Samsung, problem solved. I deleted the update, and got my clean and clear button back. I will not be updating that app for the duration of time I still have this phone. Furthermore, if this is to be Samsung's policy, going forward, to make things better by making them worse, this will be the last Samsung product I ever buy again!

    Absolutely worthless for tracking battery usage compared to the old battery usage screen before the Android 10 update. I used to be able to track my battery including Screen On Time from charge to charge automatically. Now I only see SOT by day or 2 hour blocks that I can only estimate usage between charges. Bring back the old battery usage screen! It's also funny that a few months before the S20 release my once perfect S10+ now has poor battery life so I'm forced to feel like I need to upgrade.

    No longer shows system up time. Also changed the font color to be impossible to read on dark themes. I liked to use this regularly to ensure my battery was functioning normally and lasting and that my phone was on as long as it should be before losing battery. Why would you update and show less information and make the app useless? Used tobe great.

  51. Mike Drain-avatar

    Latest update no longer has the ability to clean the cache under the storage. I have used this feature often since my old Galacy S5 and it was working on my new Galaxy S10 until now. Please return this feature. You appear to have a lot of upset people over this update and im sure you will have more one star ratings as a result.

    Please bring back feature "since last charge " I cannot see how long it has been since last charge. Also my battery seems to drain extensively since this update. I had to download 3rd party app to make apps to sleep. Note 9. Pie user interface was much better. This app is confusing and not helpful

  53. Rohan Phillips-avatar

    Samsung removed qihoo 360 cache cleaner from Device care because it was sending personal data to China. I support samsung on this. But they should have replaced qihoo 360 with any other cache cleaner because its not cleaning the junk files now. Also they have messed up the SCREEN ON TIME big time with the Android 10 update. For now I have uninstalled the update and using the previous version untill they add a cache cleaner to the app.

  54. Keith Taylor-avatar

    This used to be a great App. It is now considerably reduced in functionality by Samsung suddenly removing it's Storage Cleaning functionality, claiming that is no longer necessary. On an older Tablet like this Tab A that they sold me only 2.5 years ago, with only 16GB of storage, that cleaning function remains vital. Very poor customer service to remove it.

  55. Debra Kaminski-avatar

    Love this app; it really does an excellent job of taking care of my phone! It checks storage, battery, and memory, provides status of them, then optimizes in just a few seconds. It's greatest value to me is that it monitors apps that run in the background and gives me the option to close them, which helps keep my phone running smoothly. Strongly recommend for Samsung users.

  56. E PB-avatar

    Just like everything else. If it's not broken lets fix it anyway, no one will care or notice. Well i noticed and i don't like the downgrade and that's what this is. A downgrade and a step backwards. If i could I'd give this 0 stars but can't so you get 1

  57. DC Tech HD-avatar

    App was perfect before android 10 update, now I cannot clean the cache in one simple step leaving me to go into every app and clear cache. This has be irritating and should not have happened I now run low on storage capacity. BRING BACK STORAGE CLEANER.

  58. A Sutton-avatar

    Well besides my screen always in grey matter and my photos and files are constantly being removed as fast as i take or download them . Which i cant seem to find a setting option anywere that would allow me to have the option of that stuff not being cleaned up .also battery dies faster. Keeps erasing my stuff

  59. Google User-avatar

    This app was great & then after my last update in early February it quit optimizing. I have to manually clean the cache for a rediculous amount of apps that came with this phone. I'm not sure if the storage is even accurate. Hey guys put your app to the factory setting after you delete the updates & it will work fine again.

  60. kerry diker-avatar

    As usually samsung kills our phones and force you to buy newone. This app is not the same after update to android 10. There is no logic explanation screen on time shown after midnight period, not since last full charge the phone. When I get my S9+ display COT was 8h, now I can't reach 6h because of this battery drain condition...

  61. Adub A-avatar

    No longer works after last update. And has actually become progressively less functional over the last 6 months. Its funny how there is nothing every running in the background now. Samsung's software is the absolutely worst I have ever used. Never again.

  62. John Franklin-avatar

    What happened to the option to clean cache??? This is a headache having to go to each individual app in order to clear the cache!!! Fix this issue please. If not I'll find another app that will...

  63. Jignesh Pithva-avatar

    The Storage Cleaner Button is Disappeard in new update. This is not good for me. So many people are indicating that you have removed the cache cleaner button. But u r not taking any steps...Why so..?.. Can u explain how to clear phone cache..?

  64. Michael White-avatar

    Uninstalled thinking I'd find an older apk on the web & realized I couldn't uninstall it, but it did roll back the update so it finally clears my cache again. The Feb 20, 20 update broke this app. I don't advise updating unless/until they come out with a new one that works correctly.

  65. Rafie Rijal-avatar

    just realized that you removed an option to delete cache from certain apps in device care storage option. i'm using line and whatsapp and these 2 apps really use a lot of storage for picture/video/sticker cache and i can't delete the cache because the apps won't show up in there now. please fix/revert this because these apps really eating up a lot of space. i mean i know i can delete the apps cache from optimization but not the picture/video/sticker cache because i always have to do it manually.

  66. Omar Cabrera-avatar

    I do not like the update because it no longer gives me the option to clean the unnecessary files, when I deactivated the update and restored the application, the cleaning option appears, I really prefer to have that active option to clean my cell phone easily on a daily basis and not I understand how in the updates that option no longer appears, having this application updated I get that to free up space I must clear the cache of each application one by one.

  67. Michael Loney-avatar

    360 ties cut. Only complaints are it has a task killer and doze clone. But way better then before. I would suggest Samsung develop a very basic in house cache cleaner that cleans app cache like you can manually do per app settings, and automate it, or link to more privacy respecting cleaners like Files Go or SD Maid.

  68. John Raams-avatar

    This app appears to delete my downloaded movies from the google play movies app. Extremely frustrating to get on a plane and find that my movie library has again been emptied Really getting tired of opening my movies and finding the downloads on my SD card are gone.. I have a samsung note 8 and this is the only tool I have on the phone that has the capability to remove temp or other files.. I need to be able to tell it to ignore the sd card or certain folders

  69. Nathan Bloomfield-avatar

    Nathan Bloomfield


    Recent update takes control away from phone user and only deletes temp files under rare circumstances, and only when the app gives you the option. Now it says the phone is optimized when it clearly isn't... REVIEW UPDATE Recent update seems to be back towards the original where you can clear background data and cache storage.

  70. Jim Watson-avatar

    I rarely comment about apps, but will for this one. Samsung, why did you take away the ability to let the user optimize the storage with this latest update? You left it there for the memory and battery, why take it away from the storage? Now I'm going to have to use a third party app to clear cache and other unnecessary files and folders for a Galaxy A20. Bring back what was there before. Whoever's idea this was at Samsung to do this has made a big mistake. Read the latest comments being posted.

  71. Rayne Fi5t-avatar

    The new widget for android10 totaly sux... I've had it on my scroll left home screen for years - S7edge, S8+, S9+ & it's always been TRANSPARENT... Now it's WHITE and invasive instead of subtle and interwoven with my wallpaper... it pains me to have to use an insulting word like "pathetic" towards an otherwise legendary developer team 😔

  72. SlickJames018-avatar

    Why after the update am I unable to have automatic clear space with a touch of a button Storage comes up with files and folders like audio video n such Y no button for clear up storage like before????? It's like being stuck at 500mbs When before when I used to other way it cleared more puttin my phone to 1G of Storage

  73. T Kemp-avatar

    Why can't you just show how many hours your battery has lasted since your last charge? The app used to.. now you have to try to piece together hours from a bar chart between days. Truly awful and annoying. Still no update to make this app useful. Grade F.

  74. Natasha Gonzalez-avatar

    Natasha Gonzalez


    Useful for keeping tabs on battery and deleting excess memory and storage. Clears unnecessary clutter keeps phone operation smooth. Re ent update has slowed phone down, keeps crashing now, unable to clear cache and extra storage. Battery not optimising. Please fix what was a really good app!

  75. Robert Bruce-avatar

    This app was really great and I used it daily to keep my phone running its best... until the latest update. The option to clean the storage is no longer there. It made it quick and easy to get rid of useless files. Please bring it back.

  76. Shakhawat Hossain-avatar

    The battery usage stats has become useless since the one ui 2.0 update. I don't want to see my whole day screen on time and have to sum it up for total screen on time after last full charge. All i care about is what my total screen on time is after a full charge. Plz fix this or provide an option to switch the stats

  77. Sam Pidale-avatar

    So ok who is the moron that screwed this app up a couple days ago. Well it is worthless now. Was the vital part of my s9plus. But now can't clear cache and doesn't really put apps to sleep. Says it does but it doesn't. Was a great app. Why do you guys ruin everything. Leave it alone. God sakes.. Its really sad.

  78. Aman Kumar-avatar

    Sorry for this review but in past the app was out standing but the recent update caused the chache and temporary file cleaner disappearing. I dont know is it problem with my device or you dont let user to clean cache and temporary file. Please see that it comes back again in the next update .

  79. James Loftin-avatar

    What Happened??? 😐 Every since the latest Update, now I can't clean my apps now. It only shows "Analysis of each app. Hope you go back to the original one. All you can do now is" Clean Cache " of each app. Please fix this ASAP

    Was a five star app until the last update. Went from being the best preinstalled app on my Samsung j3 orbit to being the worst. If you can correct the problems with the app with a new update, I'll gladly give a 5 star rating, but as it stands, 1 is too many.

  81. Dan Slade-avatar

    Always loved this app and set of features but with the latest update, what happened to the clean storage/cache button? It's disappeared. It was a feature I used a lot. Am I missing something? Was definitely a 5* app before the last update.

  82. Sam V-avatar

    Newest update removes the feature in the "storage" tab to remove unnecessary files/temp files making that tab useless. It just points you towards things you can manually delete one by one by one but no longer mass erases cache of apps or temp files from image heavy apps and such. Step backwards.

  83. Christi Patrick-avatar

    Christi Patrick


    Hate the new widgets!!! Can we not have multiple options of color or transparency? I use to love having it on my home page because I used it often but now it's ugly. Plus the app doesn't seem to work as well as before to optimize my phone. Why so many bad updates? Please fix!!!

  84. Ron Ehling-avatar

    I thought it was better before. The new update wont let me clear storage. I have a prob6with that, since the app telegram pops up and destroys me connection. Clearing storage would get rid of it temporarily. I don't even have the app telegram.

  85. Chris Fortun-avatar

    I personally like the old version because you could tell how many days,hours and minutes you used from last full charge,which is a insight to the longevity of your battery.Definitely does not help too conserve my battery,seams to do the opposite

  86. Jared Brownstein-avatar

    Jared Brownstein


    Used to be useful, now the buttons for cleaning have vanished. Why would an update remove cleaning and saving buttons when they were most if the appeal in the first place? Is there any good reason for this backwards update or did someone fall asleep on the job? Correction, it is less than useless. Doesn't even do its job, just takes up space. If you removed that function, what is the point of the app?

  87. Karan Lalchandani-avatar

    Karan Lalchandani


    I want to see screen on time since last full charge and not daily basis. Does this app really clear cache? U removed 360 qihoo and now we can't clear cache. Do you have plans or suggestions on how do we clear cache in one go instead of doing it one by one for each app?

  88. Michele Mann-avatar

    I dont like that the storage is changed to where you cant clear it. I have to now go to apps and clear the cache in each and every app to get my storage on my phone cleared back up. I would like it if it would be put back on to device maintenance.

  89. Fazura Wilson-avatar

    Not working like another 3th party app..Bixby Voice,Digital Wellbeing,Galaxy Store,Map,Camera,Samsung Note,Galaxy Store,My Files,Play Store and some Samsung Bloatware still Always Running In Background and drain my S10+ battery Usage..i hate Bixby Voice & Digital Wellbeing because this app not give alternative option to disabled it..suck Samsung!!!

  90. Eric Schwartz-avatar

    Absolute garbage. Its idea of "optimizing" my phone is shutting off apps I was using, because opening Device Care put them "into the background." Would re-evaluate if it had an easy-to-find exclusion list of apps it is never to close.

  91. Jenny Hurst-avatar

    This app will help your phone and you will get a lot of information on and from this huge AMOUNT of enjoyable content that I can use it for all files or folders to download or delete!!! Great for optimised and convenient access for cleaning up ur phone

  92. George Rivera-avatar

    Surprised. Just moved up from my lg. It was labeled an entry level phone. My new a10e is full of surprises. I guess trickle down engineering applies on phones Oops, the device care app is a blessing in disguise as it keeps my phone charged all day. Thank you to the engineers.

  93. Maria Mello-avatar

    After this last update I've had CONTINUOUS problems with my phone freezing, knocking me out of apps, & weird data popping up. Please fix the bugs created by this last update. Thank you in advance

  94. Dwayne Miller-avatar

    I love this app on all my Samsung devices but the recent update to Android 10 has been a mixed bag , as i love the new ui design but i cant get my Screen on Time to show as before after the last full charge as opposed to now where it shows my screen on time at the beginning of the day no matter what

  95. Ladyinwaiting-avatar

    Last update screwed up the app. Not only does it barely work, but it's become pointless. I can no longer clean cashe regularly, in fact I can't clean them at all. This app was better before. This app deserves ZERO stars and needs serious fixing.

  96. Khalid Khalil-avatar

    I regret that I have updated this application because it lost its most important feature and became very bad, ecpesially the button that supposed to clear cache. It doesn't even exist Samsung? I'm Waiting the next fix update & i wish you will listening to users (Android 9)

  97. Roy Ballain-avatar

    This app was once great but the new update just screwed everything up I can't clean my storage and I do that on the regular bases my phone was always easy to keep up on managing it but now I can't please give use back the old device care because this new one does not work at all please fix it

    Bad bad bad!! Clean internal storage button is gone. Now, I can not free space from internal storage. This update itself is a major bug (intended functionality/blunder). Please resolve this bug

  99. R A-avatar

    Its a basic honest needed function. This app is cute it feels warm & fuzzy it cares about me - it's technically assisting, right. I would like to know what is being stopped removed stored and see cache dumped regularly (which is never dumped).

  100. Sandra Danagher-avatar

    Sandra Danagher


    This app used to be great for clearing unnecessary data from my storage, now however, it's a completely pointless waste of space since this function was removed. I'm really disappointed with the update and hope you bring it back soon.
