KR Service Menu - LG G6 Questions and Answers

Looking to go the ADB route to disable system apps, I'm just wondering what the KR Service Menu is for since the devic shows that it has been using battery. I tried searching about it but nothing much comes up. Hope someone can help thanks

I disabled mine and no issues. Not sure what it does.

My phone keeps losing 3G connection!

Hi,
To be clear there is no problem if 3G is running, it doesn't drop.
The problem is that sometimes I unlock the phone and 3G doesn't connect at all.
So I checked:
1- The APN setting are correct.
2- I reinstalled the internet setting automatically.
3- I don't have a task killer.
4- I deleted juiceDefender.
5- The only way to get the 3G back is to restart the phone.
How to solve this? I don't know why does it happen, and if I restart the phone every thing goes back to normal!
* My phone is rooted ..
Thanks ..

I had this same problem, too. I fixed it by reinstalling JuiceDefender, making sure it was disabled and then uninstalling it. I found that if you un installed JD while it was 'active' causes the phone to stuff up the APN somehow.

I made sure JuiceDefender was disabled before I uninstalled it ..
* by the way, I'm also using "optus" .. can they be the problem?

I have completely lost my 3G connection and don't know why! The only thing i did was download an update for Handcent. I have switched off my phone and removed my sim card, etc. but still no 3G. When i enter the APN section my connection reads:
_DISABLED_payandgo.o2.co.uk
I have no idea what could have disabled this but i did delete the _DISABLED_ from the address but still no success.
Any help would be much appreciated.
Kind regards

Hi! I have just managed to reconnect to 3G having performed the following procedure:
Within the APNs section of mobile network settings press the left hand button with the four squares. This should bring up two options 'New APN' and 'Reset to Default'. As soon as I pressed 'reset to default' my 3G was instantly restored.
Hope this helps others experiencing similar problems.
Kind regards

Hi,
I managed to reconnect the 3G too! By changing the Network mode to GSM only, then back to GSM/WCDMA ..
But why does it happen in the first place!?

[Q] Enabling push notifications

It appears that applications, such as textplus, are unable to notify the User while the program is not in focus due to push notifications not being compatible with the fire. Is this something that can be turned on or installed or is it further down than that? I clearly don't know a ton about the system, just figuring this stuff out. Any information you can offer is appreciated. Thanks!
I think the problem is that wifi shuts off when the screen is turned off. Anyone have a solution for this?
Even if I am using the device I wont get a notification. However, if wifi is off with the screen that is a huge problem as well. I didn't even think about that. Thanks
Wifi keep alive app will help.

S7 Edge Issues

Hi All,
I've had the S7 Edge now for 3 months and I am generally loving the phone. However I have a few issues that are happening continoulsy:
Bluetooth turns itself on and the volume of the phone mutes itself.
Wifi turns itself off during the night even though I've selected the option to keep it on. I will wake in the morning and the phone is using my mobile providers data.
I have read various threads to factory reset the phone which I will do if it resolves the issues but I want to ensure my Apps return with the data they currently have residing in them e.g. 1Password etc.
Hoping someone has some thoughts,
Thanks.

Did those issues always occur or start only recently?
Hi,
From memory they have always been there. I've just lived with them but they are becoming annoying.
Thanks.

this is not a common issue and I believe you got a defective unit. you should take it back to make warranty claim
I'll have a word with Samsung support. I would have thought that the software was telling it to do these things.

In the wifi settings, try disabling wifi smart network and setting also wifi always active on standby (the actual menu setting names might differ, I translated from italian).

Unfortunately I've tried all of those to no avail. Today the phone has 4 times muted itself and in addition Bluetooth has turned itself on automatically. All bizarre!
Do you use the edge panel "My Places?" This can change those settings based on location.

Unfortunately not I don't use it. I wish I did as that may be an answer! It happens all over to be honest and isn't linked to a certain location. It's very odd as I can be using the phone and suddenly it turns mute on. Sometimes bluetooth will turn on with it and sometimes not. Its frustrating as I am now missing calls and texts.
Appreciate any feedback.

Apps - application manager - apps that can change system settings. (names my differ. Translated from my language). See if any user app that you installed is enabled in there or try troubleshoot by disable one at a time.

Okay I've disabled them all for now. If things stop working I'll enable them one by one. There were a few that had access. Appreciate your help.
Just as an aside what is the best way to factory reset the phone and then reinstall the apps etc that I had installed. I'm thinking worst case if what you have proposed doesn't work? I had an iPhone prior to this and it was a pretty straight forward process.
Thanks.

I'm not TOTALLY sure, but I think that if you're logged in with your google account and go into settings->Backup and choose to backup to your google account, your app data should follow. After the backup is finished, factory reset and then when you log into your google account again you get an option to retrieve your old app+data.
Don't hang me up on this, as i'm not totally sure! But i THINK it works this way. Google at least mention app data in the decription, but well, not sure if everything follows.

BT keeps turning off

For the past few days, my BT setting keeps turning itself off every few hours. Once it happens, it then continues to turn itself off immediately each time I re-enable it. After an hour or so, it recovers and lets me turn it back on (until the next time a few hours later).
The phone is completely stock (APK1), never rooted, no 3rd-party power-saving, task-managing, or security apps ever installed, no power-saving modes turned on. It does not help to clear the system cache or the Bluetooth Share cache. Closing all open apps does not help. Rebooting sometimes helps temporarily, sometimes not even temporarily. I haven't seen the problem when I reboot in Safe Mode, so either it's caused by an app (I have hundreds), or else I just didn't leave it in Safe Mode for long enough for the problem to reappear. I have not recently installed any apps or made any settings changes. I've searched online and come across many suggestions but none are applicable and successful here.
Is there a system log somewhere that would tell me what is turning off the BT setting?

Wouldn't that delete all my WiFi passwords? I find several online mentions of people who unsuccessfully tried Reset Networks to solve BT problems, and no mentions of it being successful.

Try one more thing : Settings-> Applications-> in right top corner you have 3 dots, press and choose Show System Apps
scroll to Bluetooth share , click on it then click on Storage and Clear Data. go back and do same with Bluetooth Test.
Thanks, but that didn't help either. I found the culprit, though: the Walgreens app. When I force-stop it and then turn on BT, BT stays on. As soon as I start the app again, BT turns off. And I now see many other user reports of this problem, going back a couple of months.
It's annoying that without the user's knowledge or consent, Android gives an app unnecessary permission to turn BT off. What's worse is that there's no easy way to identify who turned it off.

There is an app in the store called App Brain Ad Detector.
After you install it you can scan all your installed apps and it will break down all permissions given to each app, show which ad network, etc. It is very useful!
Also after it is installed when you install a new app it will report if it does things not normal.. IE it would probably have caught that BT permission!

"Settings has stopped" and "Settings keeps stopping"

Hi, its my first time writing here, but not using this forum.
First of all, sorry if my english is not good enough.
I have a Nexus 6P stock, without root or anything. This week I installed Android 7.1.2 from google beta program, after that, I was having draining battery issue, so, I checked the battery usage and discover that the Wi-Fi never stop, then, after reading on some blogs about this problem and found that I should go to WiFi setting and disable some option in "keep wifi on sleep", however, when i click on setting key, always appear this messages "Settings has stopped" and "Settings keeps stopping". Things I did:
1) Disable Wi-Fi, try clicking on setting key - still the problem
2) Restart on safe mode - still the problem
3) clean the cache from recovery mode - still the problem
Any other suggestions without restoring the cell phone?
Thanks in advance

Hi... The gear icon force close... It's a bug in this beta version, nothing you should worry about.
However, I have no idea for your battery drain...

Have You tried with - Settings - Location - press the 3 dots - Scanning - And disableing everything there ?
So...if I can't access the wifi settings is there any way to disable the wifi optimization or otherwise prevent it from dropping a wifi connection that it detects has no internet?

Unfortunately the only thing that usually fixes that is a factory reset. And if that doesn't work it's a ROM issue. Even though it's a stock ROM it happens.
Your best bet is probably a factory reset at this point. Usually if Settings or another system app is crashing on Stock, something is pretty messed up. You could either opt out of the beta and it will wipe/downgrade for you, or you can download a factory image from Google and install it manually if you're so inclined.
I have the same issue on my s6 after it updated to Nougat. Settings crashes every time if I try to open wifi, no matter what. Already wiped system cache and started in safe mode, but the problem is still there. Has anybody figured out a solution to this?
Did you try what was suggested..... ?

I tried everything except factory reset, which I don't want to do yet.
I have this problem but I'm running Nougat on a stock "International" Samsung Galaxy S7.
I've tried factory resetting which fixed the issue for a while, but now it's come back.

I may have found a possible fix for this issue. Head over to this Android Central Thread where I've been discussing the issue with some other people.
Good luck!
