Reviews From google play store

I love your app Francisco! I bought it missing out on the freebie deal. However it's awesome and I also have your other apps. Please build a current Miui compatible kernel for the Mi8, I will pay. It couldn't be too different from the Poco version ? Either way Thanks for your work?!

5/5 this kernel manager is simply amazing. The developer can be cocky at times and not the good kind, but I'd recommend this kernel manager to anyone.


Best kernel manager out there 👌

Excellent. ⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐⭐ Good for gaming, battery backup. Edit: Lag every 3 seconds on pubg. Battery backup is not good compared to underground #mido

Hello. I think I've found a Bug. Dunno if it's intentional or a Bug. I'm using a OnePlus 6T, running the latest OOS 9.0.17 and the bug is in the Battery Monitor Service. For some reason it's been counting my Screen On time far more than it actually is. For Example, Battery Monitor says my Screen On is 2 Hours whereas in the Device Settings it's only 40 Minutes and I know for a fact I didn't use my phone for 2 hours. I don't have this issue on AOSP ROMs tho. Only on OOS and noticed it yesterday.

If u change device not support. Pls check before buy.

No sure yet what to thing of this apk. Purchased so I could flash twrp without using a computer. Had little luck. Booted to splash screen and stuck there. Had to reflash my boot IMG using the PC and then fastboot twrp. Seems like a waste so far for almost $5 I'll update review down the road once I've had some better luck. Was able to back up boot image but haven't tested it yet

Amazing franco kernal for Poco F1. If you are looking to get the most of your device, trust me you landed to right place. Just the pay the slightest of slight amount for the app and it will be worth of every penny.

Sorry 4 stars, this app is great but cpu cores detection is mismatch on my device

Looks great, no ads, many options (not that I use all of them, but why not 😂), I ADORE the design, it deserves 5 stars :)

Firstly it supports Mi A1 but now its not supporting at all..Money wasted please refund my money.

In latest update , where performance profile ? Ex battery , balance , performance. Sometime i need simple setting :(

It lower the small core frequency to 844 mhz. Also zram size increase or decrease or enable or disable don't happen to occure untill 10 tries.

Fully accessible to the device through this kernal manager....


Great app and also great kernel!

Best kernel manager. Must have. 10/10

After update max gpu frequency is shown twice in the list.

This manager's da bomb 😁

One of the best kernel version managers available till date, totally recommend it

Best of the best. Great work, Francisco. Keep up

best kernel manager app and Franco is really nice guy

Any support for x86


Hi, I have to hide magisk manager with the build in hide function so that banking app can work. But then this app will complain no root but in fact there is root. And other root app works. Please don't just check if magisk manager is installed. When I un hide magisk manager, it can detect root perfectly. Updates: Fixed with reinstall and hide magisk again

EDIT: I've kept FK up to date, but haven't changed any settings in a long time. I'm sure I changed the vibration intensity before the tabbed interface. There is no VIBRATION tab in KERNEL SETTINGS for my phone. Adding "/sys/drv2605/rtp_strength" to the CUSTOM TUNABLES tab at least let's me control it. ORIG: Kernel r76 on Nexus 6 (7.1.1; N8I11F; Oct. 5, 2017 security patch level)

Very well done app. Made a huge difference to my backup OnePlus One. Great work

good... And yes sir.. while iam playing pubg the fk will force stop's Also it takes more time to refresh its settings when the device is rebooted

Why it keeps saying I have illegel app while I bought this app from play store? Edit: it worked ☺️

Can't set I/O scheduler for my microSD card; had to use another app. Battery monitoring is the real highlight of this app—plenty of detail, helps you dial down your kernel settings, minimal RAM usage unlike *cough* other apps that also load in Google Analytics in the background in the paid version *cough*

One stop for kernel Manager.

this is the 'App of the year' for me thanks man.. keep developing apps like this

Best kernel manager for Custom ROM, the Franco kernel is not that good(should be different for other person, I use Poco f1 with PE PLUS 9), I would like to buy the app but if you provide a little bit discount. The per app profiling is great, tips to maximize battery life is the best, underclocking the CPU and GPU when needed. It's good that the dev gave all the features with out the pro mode,I would like to make a donation but buying the app for 920 rupees is not my option.

Apllied settings going to default even aftern turning switch on. How to fix

Edit 2:- overclock in other ways are fine . I can switch performance profile anytime without any problem. But app specific profile doesn't apply every time. Every time i have to restart my phone and it will apply 4-5 time. I'm using latest franco kernel and fk app. All good but per app profile not applied sometime which is disappointed. I choose this kernel to overclock cpu and gpu for pubg mobile. But it's not working most of the time. If you'll fix my problem I'll change my review.

Best kernel manager ever

I can say that this kernel manager is one of the most effective kernel managers for oreo and pie right now

Sorry to tell you but m running Android 10 and OP has removed the Deep Sleep optimisations and it like how Google wanted it in Android 10. Another thing is I m using your app on my OP3 n 3T and Poco F1 and z2 plus, Mi A1 and O7. Except OP7 all are running Custom roms and I have not done anything which kills them in background like agreesive battery or make them doze faster like your app Naptime does. I am clearly stating u here after a month of Fickling around that exkm is working properly.

nice app fully functional

When you update kernel for all android type

Great app

I want to use franco kernel but there's nothing there just isn't there for sagit?

Its easy to use

Best kernel manager out there, with a beautiful UI! Have this installed on both my Pixel XL and 3a. One suggestion though: the ability to edit per-app profiles after the fact. Edit: the simple layout

Love it

Love how much you can fine tune your android using this app.

one of the best kernel manager!

Keeps constantly resetting my max CPU lower then my stock CPU speed thus instead of overclocking my CPU it's drastically underclocking my CPU no matter what I do.. please fix this.. also it's called Android 10 not 'Q' :)

Thanks for latest update. Does the per app profiler works with other kernel?

Great app. Worth every penny.

Great app, actually purchased it when I could have had it for free (it was worth it!) still waiting on a kernel for the OP7 Pro, but I use to to manage everything else kernel related in the mean time, and I use the battery monitor very frequently! Well done man

Nice app

Wow app was completely redone and it works great now! Thanks Franco!

Great Kernel Manager! Works flawless, keep it up 👍

Could I get a User Guide Manual for all available setting and tweaks?

This app is absolutely awesome I can tweak my phone to the absolute tiniest of details. Only thing I wish they were more instructions to help me.

Perfect 👌

Excellent kernel manager 😍 it would be great if you could add dnd in per-app profile cuz i want to apply it on a game so that i can play it without any interference 😋, will you dev? Thanks for this awesome kernel manager!!!

Alright! Uninstalled and reinstalled! It starts working again! :D thanks for your time mate! People like you are keeping android alive with all your hard work! I really wish I could donate, but sometime soon!

I can't seem to see flasher's download zip. and I want refund :/

I don't have a Franco kernel supported device anymore, but the days when I do it's always a blast with his kernel, so I decide to bought this kernel for the second time on my new device, and keep it as a memento, truly the best dev out there


I hope big clock freq not raming up will be fixed ty

i give 5 star because i got it for free but after update v.4.6 it somehow reset the frequency of both cpu and gpu i cannot set it to maximum clock speed ( i use custom kernel from franco and other kernel it gives same result ) edit : crisis averted nothing to report

Quite good app for managing your phone. I've been using it on mido and I am satisfied.

This is the most user friendly kernel manager out there without being restrictive to power users, at all. I love it and so will you if you are reading this.


Great kernel manager even without franco kernel, love battery monitor. Little update, i change phone that has no kernel support and no root but this app still very useful with the battery monitor so i will not change my rating Keep up the good work , thanks

Simply awesome.

Great app, with great updates Using this app for around 2 months. The best feature i love is battery monitor stats and the most intuitive ui

Perhaps the best app on the Play Store

Best kernel manager ever used. Awesome experience until now.

Does not make me morning coffee. Does not clean my toilet. Poor conversation skills. 0/5 stars. Kernel and app are OK though. UPDATE 6 YEARS LATER: Still using this app, and everything still works even though the device I use now doesn't have a Franco kernel available. Thanks mate!

Wait for Kernel already on my device (Samsung S9+ Exynos 9810)

Absolutely recommendable.

I purchased it when It was On Sale and Free, But I installed again and In Google play it says Purchased. But when I opened it It says Not Purchased. Update : Issue Solved, Just Had to Reinstall The App.

Excellent UI and structure/ease of use! Also, has many 'info' buttons, to educate you on more advanced functions. Compatible {Kernel} w/LOS&AOSP custom ROMs. PIE as well. SUPPORTED WELL! @Francisco Franco - I have been busy but preparing pictures/video of bug with SOME CPU/GPU settings sticking in the app. Not only are they being reset upon reboot, but as soon as you go back from "CPU" or "Kernel Settings" tabs, they reset. I will address fully on your XDA thread for your Kernel on OP5

Great app for monitoring your CPU etc. Sadly Kernel flash errors in Nexus 6P Pixel experience Rom. Refunded.

Can you please make earphone Gain to go in negative like kernel auditor

This app keeps getting better and better. Dev is very responsive. To dev: the bug is fixed in 4.5.1. Thanks a lot!

Wallpaper changed after flashing the kernel. Wont let me use another one. Simply doesnt change anything when i select.

If you're looking for the best kernel manager, this is it. Fluid UI, amazing developer who's close with the community (kudos to Franco for adding a feature I requested); the battery monitor and flasher are very handy. 10/10 would recommend to everyone.

GPU setting is not working

One of the best I tried. Never going back to the other kernel manager anymore. People giving 1* review saying they can't use it without root is effing stupid. Of course you need root. duh.

Please we need kernel for Samsung note 3 n9005 very important

don't now how to used it say not support my device

i have xiaomi poco f1 indian version..and i have its factory charger which is of 18watts as claimed by the factory..but when i charge with it ,this fk kernel manager says that there is 29 watt charging ... how's that possible ?? because i have 18watt charger

Great kernal manager.

tips and battery monitor all starting at boot again. thanks for the fix

Amazingly Done, Yet once again! The new update seriously pushed me back to rewrite the review furthermore, The detailed stats are what I needed. Thank you so much once again for this amazing app! Regards,




Very good app provides charger charging capacity along with stats

Absolutely a must have - great app

5/5 Loving the updated version even more. ❤️ Dang the battery monitor is super useful now. Truck load of important details and little stuffs.. Thank you Mr. Francisco.

Best kernel manager I've used. Feature rich, support is great, and it looks real nice too.

Compared to other kernel managers Franco kernel is best one 👌👌

To good
