***This app require ROOT permission and base on QUALCOMM chipset***

Network Signal Guru (NSG) is a multi-functional Android OS based tool for voice and data service quality troubleshooting, RF optimization and engineering field work. It supports all wireless network technologies worldwide, and covers multiple mobile layers as well as data stack in real-time. NSG provides extensive test functions for voice, data tests to assess and reflect the real end-user experience of QoS within a mobile network. 

NSG covers all test functions and latest technologies such as: GSM, GPRS, EDGE, UMTS, HSDPA, HSUPA, CDMA2000, EVDO, LTE(FDD & TDD). NSG integrates full recording and decoding of protocol layers on the supported technologies(3GPP, Layer2, Layer3 and SIP) and direct decoding of Layer 3 signaling and data protocol packets on cell phones.

NSG Map offers comprehensive and valuable benefits to combine outdoor and indoor measurements, which reduces the complexity of in locations such as subway, malls or airports. 

NSG needs two prequisite conditions before you are using this tool. first only support Qualcomm chipset models. Secondly NSG need cell phone a super user access within your android phone and you have to root the device before NSG is running. 

What that NSG team is doing right now is to lower the cost of network maintenance, optimization and engineering processes. Currently a lot of test tools provided in the market are very expensive, some of those are much more expensive than a basestation. That’s why NSG Team launch this app. Please help us more users and carriers can get benefits from this APP. 

Band Locking enables you to allow your phone to only search for service on the bands that you specify. This is important if you are trying to identify specific coverage in specific locations, or do other testing with your phone. Additionally, if you find that one band is severely congested, you can force your phone to stay on a different particular band.Network Signal Guru is a new app that gives TONS of information on the cellular networks that you are connected to.

Thanks and Best Regards,

NSG Team

Reviews From google play store

When I open the app, the app automatically keeps changing to different tabs within the app without me doing anything. Even if I select a particular tab to view the info in it, the app switches to another tab by itself. Frustration to read any info. Band lock does work though, but sometimes requires a reboot.

Useless for my needs as users can no longer force lock network bands, till this issue is fixed this app main reason for installation on Android device is useless and if I could give it zero I would. Note:does not work for Axon7, LG G3, LG G4 and Pixel 3aXL all these devices are Qualcomm SoC based.

Band Locking stopped working now... I cant lock to a particular band anymore. Facing the problem since a few days..

App has stopped working. Since october 2019. Please fix ASAP

2.9.5 is now working again in Android 10! Thanks!

Earlier It won't shutdown the phone when changing Bands

Doesn't work anymore on Razer Phone 2 Rooted Android Pie. Did work on Android 8.1. Always says Driver not found.

Edit :Working on redmi note 7 pro stock rom as there is very poor network management in this fone this app helps lot to select and lock specific 4g band

Working fine on Android 10. Can you guys please at support for dual sim? Thanks!

Edit: it's working again. Probably had some problem with the kernel.

Getting error 'Driver not found' in Android 9. Any fix ?

5 star if locking on sim 2 is enabled.

Impressive app but $50 month is out of reach for majority of users. Would be nice if they had something other than ultimate edition. I only want locking support, wouldn't mind paying a onetime fee or something like $1/month for it.

Awesome app.. fully useful for me..

too pricey but single app to lock the bands

I love the app, it has worked for exactly what I need. HOWEVER, since I may need to use it for additional phones, I need to know which devices LTE band locking works for. For example, Samsung Galaxy S7 SM-930V ROOTED on a Snapdragon 820 with an ENG Oreo 8.0 with a does NOT allow LTE band locking. However, the Moto Z Play ROOTED on a Snapdragon 625 with an ENG (I believe) Oreo 8.0 does allow LTE band locking. Do you have a compiled lists for which devices LTE bands work for, or is it a Snapdragon model issue?

Great app for seeing information about the mobile network you are using. Lots of detail even in the free version.

Did you guys remove the LTE band lockng on free version? I only used to lock LTE band with this so buying the full version doesn't make any sense. And if this thing is because of my settings or something then please respond. I don't want to spoil your ratings because of that.

Good information in free app, but subscription fee is ridiculous. I just want to lock the band.

it is working fine now on mi note 7 pro.

Superb. It allows band detection and control.

Only app that lets me lock LTE bands to what I want and get the best LTE speeds. Requires root but its worth it.

I used this app for 4G band locking.. But it's not locking bands anymore. Android 8.1 Device Redmi Note 3 Pro. Plz fix. Thank you :)

The best app for a rooted phone.

useless app. not working on my poco with custom rom. Edit: went back to stock rom and it worked. Changing review to 5*.

Best app for checking netwoek info but Not working on Android Q!

It has stopped working on locking LTE band on Android Pie redmi note 3.

not working on poco f1

Definitely the best app for knowing your mobile network

Great for having network problems.. :)

downloaded the app in my ZTE Z982 and i couldn't use it. Its showing Root not found

Band locking is missing on the latest update 🙁

No longer works with Android Q on a pixel 2 xl

Doesn't work on my Samsung Galaxy S10 on Android 9👎🏻

Literally one of a kind, Dont know of a single product out there like it that doesn't require it's own kernel or a completely dated version of android! or requires physical attachment to a PC. The best thing is, Even without a rooted device, the replay works on qualcom log files.. This makes it so adaptable! Can't wait to see what else the NSG team bring out!

Version 2.9.4 broke band/RAT locking on Moto Z2 Force, a SD 835 device. Fails step 3 when loading configs. I downgraded to an older version for now.

Love This app. Very useful for me to lock bands. And developer of this app is also very helpful and responsive.

Not working, almost all functions require payment. On top it wants phone to be rooted.

Error in locking band

First of all, the app works great. However, the cost just to stop the pages from scrolling and the ad to go away is completely well out of the price range for most of us enthusiasts! I understand that you're targeting this to more professionals but there are a lot of enthusiasts like us who use it not for the professional features but for simple band locking and cell identifying. I'm someone who owns several phones to identify and map cells as a hobby, not profit, so $50/month is way too much. Please, consider a much cheaper version for us so that we can continue doing what we do!

Works but when I force to LTE band 3 my phone(poco f1) keeps jumping from band 3 to band 40 back and forth for few minutes then locks on to band 3. This was not the case in my older phone (Mi4i).

Can't even opened the app

The absolute best application out there for viewing real data. As long as you have root, this app will show you carrier aggregation status. Real time SINR and other quality status. All the way down to the SIP messages exchanged as part of VoLTE. There is no other application out there that will provide you with more accurate real time data.

cant entering apps in android 10, xiaomi mi9

used to work great on Android 7. after 9.0 update it does not lock bands anymore. im on rooted version. edit: It turned out to be a problem with my operator there was too much signal disturbance in my area which kept switching my bands from band-03/1800 to band 40. The problem has been fixed and i ran the app on 9.0 and it works as intended.

Greatest cell diagnostic app ever created! This app allows one to view full information from cellphone's modem. It also allows the important feature of locking bands so phone can be forced to less busy signals or signals that travel further. NSG is an app designed for the professional and power user, there are a handful of features only a cell engineer will find useful or understand the meaning of.

It's really great app with unique features! Price should be ok for professional users. Please, consider to issue a license for amateurs (non-professional users) with dual SIM support and without really professional features like logging, automation, map creation, etc. Thank you!

band locking lte working great, but sometimes it disables(and turning off ofcourse) my mobile data and i cant even re-enable it, so i dont have access to internet at all and i have to reboot the phone before i can use it. after reboot it works normal and band locking still applied, but is there any other workaround other than rebooting? please fix this in the future, im using Mi A2 Lite

Just a blank screen with an ad at the top. You click into one of the settings and it asks for $50/mo. LOL!

Heafty subscription fee needed for locking bands. Otherwise its just useless.

rooted and granted : passed Qualcomm drivers and baseband : passed forcing and control features : no forcing features Device : Sony Xperia XZ Premium Dual G8142 (Android Pie 9) This app would work flawless on my Sony Xperia XZs Dual G8232 (Android Oreo 8.0) but on XZ Premium (Android Pie 9) forcing and control features missing. please include this device configuration in your next release..

The app is very good but there's a major issue in Android 9 pie...Whenever I change network bands I am not able to receive incoming calls.. I need to restart my device to receive incoming calls.. This issue was not there in Android 8.1 oreo hope it fixes soon in next update

Failed to receive online configuration, same as reported by many. I don't know why network goes empty bars during the configuration process, is this a bug or something... Please correct it, I require this app. I have used stock and several custom roms of Redmi 4A, however, issue is the same...

I am using this app on my OnePlus 6 and was working great. But lately I've had my phone formatted. Soon after than whenever I'm using this app I facing “Forcing and Control Feature” error. (I'm on magisk 18.1 with Android Pie running on my device). Thanks.

not working for asus max pro m1 with sd 636

if used on a device with dual SIM, the app goes crazy. workaround is to disable one of the SIMs

Awesome application. I like to calculate all networking signal in one apps. Thanks to developer

Fantastic app indeed! No matter if your using the free version or the full version it provides great detail that's either very useful or fascinating. For me, it's both. Highly recommended app! 5* rating!

its good ..but please make it available foe android 10 devices..

Not working in my Realme X device ..why??any trick please Revert?

Very good app for locking specific band, one problem: when I lock the phone on specific LTE band the pages whitin the app switch very very fast , can I pause them to move to other page manually? EDIT:this problem happens when I have 2 SIM cards active in the same time!

Help! My network is unable to get back to voLTE, I've cleared all forcing but unable to revert back, my data connection is lost via cellular network, such disgusting, no improvement over reboot!!!!

Excellent tool for network testing. I understood perpetual licence comes with more tools for offline analysis, would love to test those. Keep up the good work.

I was able to use this app on my previous device which was Lenovo ZUK Z2 Plus and it worked like charm but now on my new phone which is POCO F1 it is not working say " # forcing and control fearures: drivers not working or unkown error". Please add a fix for it.

I blocked 2300mhz. Everything works fine even after changing ROM. But the problem is I can't allow 2300mhz. App just freezes when I try to and there is no change in frequency

Can't scroll the message list. Can't pause logging. Can't see the content of the messages. Can't use QXDM or any other Telecom tools when this app is running.

Great App for mobile network testing. Once you have rooted your qualcomm device you can lock 2G/3G/4G bands, frequencies, rats, even individual masts sectors etc. I use it daily!

Best app... Just tweaked some bands n getting higher internet speed.... After new update the app is not working. It shows internet error every time but my internet is working fine... Pls fix this..

whenever i start the app it requests online configurations and the network connection gets lost every time. after that it asks to check internet connection... The app won't start whatever i do...

very good app. use it very often to test networks, has a wide range of features which i now rely on daily. developer is very quick to fix issues.

Best signal diagnostics tool hands down!

Not working on android Q Pls fix this asap 🙏

Really great app

the app keeps scrolling randomly through its pages and each 2 seconds. I can't do anything to stop it.

Is second sim slot supported? Whatever changes I make are happening with first sim slot. Its forcing me to use first sim slot which is hybrid so I cant use sdcard. Need help. App works great otherwise. Edit : will second sim slot support come in near future?

Superb mobile radio band management app. Easy to read UX and great range of tooling options. Highly recommended

Whenever I try to Lock Band 40 (2300) the app crash and no change in frequency.Works perfectly on Band 3 (1800+). please fix it.

seems like the latest version not working. after few minutes my network change back to 3G. Edited my review before

Chinese app with root access and need to connect to internet so that app can run? Nah. Too much privacy at stake. Better don't install this.

Nothing is free here.

Used the app for band locking and it worked like a charm!!! Saved me from flashing anything to lock to a band.

Great app for an amateur networks tester like me, with room for improvements.

used to work on oreo but now on pie band locking doesn't work please help Device OnePlus 3 Android Version Pie , Snapdragon 820 Update - looks like on pie band only locks in 1st SIM, Now Working Fine

Working Very Fine...! I'm Very happy with this App but Doubt about Payment showing USD 50 / month...! Please Confirm me it is free or Paid for Common User Like me..!!

Randomly scrolls through different tabs if dual SIM is active. Please fix this bug.

earlier version was working fine new version not working when i roll back to older version message pops up update your app

after installed and get online configuration,my phone get hot and my battery dropped very fast.

fake app. 50 usd per month! be careful

this app is excellent work..😘😘 my asus zenphone max pro M1.. Thanks to all of developer team...

only able to lock properly for band 3,5 but when i try to lock to band 40 phone switch off .

only legit app that works truely.. requires root access but its worth it

Very good app to control bandwidth selection of your smartphone.

Screen scrolling left right at speeds that I can't read a single word.

doesn't work on locking band on my OnePlus 5T. Also the page keep swiping by itself.

Wow! This app is simply amazing! If you don't know how to use it please don't leave a bad feedback!

used to work on my coolpad note 5 bit now shows *driver not working or unknown error* HELP

Hope there is a feature that disable lte ca , my country has 4G+ / LTE+ but it's sucks , the normal LTE is better than LTE+ sometimes.

Any way to make things easier for lte+ devices n configuration? Becoz changing bands results in sucess but changing back to default or clearing the forced bands results bootloop in 845. I m using a poco

Useful app for me ,kudos to developer, it solved my problem with jio network.
