Hello people,
today i encountered a strange behaving of my i9505 (100% stock),
suddenly the sensors stopped working at all (CPU-Z shows name, but no values of the sensors)
and there´s a massive lag when waking up the device from deep sleep and putting it into it with the power button.
Have anybody experienced this before /knows a solution?
i´m so thankful for answers!
/edit:
i tried:
# a factory reset from the settings menu
# wiping data/factory reset / wipe cache from CWM
greetings, klaus
Anyone?
I had the same problem, sensor were not working at all. I've sent the phone for warranty repair. They have changed motherboard and sensors.
Wipe didn't help mi either
The strange thing is ALL of them stopped working. *#0*# sensor test just shows freezed values
very possible motherboard problem. it is very unusual that all sensors stop working at once.
you should sent it to repair...

Most likely a Motherboard problem.

Hey guys,
I am having 2012 wifi 8GB N7 for more than yr now and have recently started getting irritating problem making it unusable.
Its behaving as if its power button is continuously pressed even when i am not touching the tablet or sound / power buttons. Its operating on its own to restart, bring power menu in every situation i put it in, like in system standby condition, powered down condition or in bootloader or even in CWM recovery. Its operating function corresponding to power button.
Tablet is out of warranty so i am trying to troubleshoot and fix it myself (as far as i can) and but getting any clues from online available material too. Also out of warranty repairs are costly / worthless if service guy decide to change its PCB.
If anyone has faced similar issue/ got solution/ got it fixed from service guys, please suggest me what can be done. Is it a software issue or hardware issue like.
So far I have tried factory roms of 4.2.2, 4.3, CM versions and AOKP versions in rooted, non rooted, bootloader locked unlocked conditions. And from my understanding its not related to any roms. Heck it shows this erratic behavior even in bootloader mode or in CWM recovery.
Can there be anything which service guys do as far as software is concerned which we cant do, so that i can give them to fix it?
Looks like a hardware issue. The internal part of the button may be loose.

Ain't nobody faced such issue ever? Please guys i need some inputs.
So far i tried disconnecting power/ volume button strip/ cable from motherboard and let it idle for sometime. Even tried booting with that strip removed, but it didnt solve the problem. So my thinking of this strip being the culprit is wrong (from my understanding).
Thought of giving an update to this issue..
Dismantled N7 completely taking help of youtube videos. Booted back up and problem persisted but with extreme low frequency. i.e. power command executed on its own after a long time. So used tablet for half and hr, updated it to 4.4.2 which was not possible in the condition it was in before. Later problem aggravated to initial level again. i.e. continuous restart, no operation possible.
So left tablet in powered off condition for a day. Switched it on again. And could use it for same half an hr without facing any problem. After that problem started troubling again.
If anyone can think of resolution, would appreciate assistance.
Thanks.
Another pleasant update.
Tab was lying unused for months with battery fully discharged. And later when i checked at random without even expecting any change in its condition..... it started perfectly.
And its working without any issue now. Hope this will help someone else facing problem.
Hello,
As you can see my issue is related to the screen... backlight always worked until some days ago where it failed somehow.
It started to fail when I flashed Stock Kitkat with the recovery but I don't think that it could be related...
My question is simple, did anyone faced this issue and resolved it?
My guess is that it has to be repaired but if there is a small chance it can be repaired from my side without opening it I'm willing to try it, otherwise it goes to reparation
[EDIT]
Apart from this issue the phone is working just fine, I mean it boots correctly, can enter in download/factory reset mode if I want too.
The only thing is if I adjust the brightness on the phone from Android nothing change, the phone is still dark and can hardly see what's in the screen.
[/EDIT]
Thanks in advance!
Bought my G2(D802) a week ago and updated it to 20b that day. Since then the only issue I had was a screen problem. I ticked "Show Touches" from Developer Options and observed. Twice a day, a ghost finger touches the screen. I can see touching dots and it makes it randomly on the screen.
So, I thought that Hard Reset may can solve this cause it seems like a software problem and I couldn't find anybody who suffers from this problem on the internet.
Not lying, I tried to hard reset like 40 times but nothing was happening every time. I tried both: Reset for before 20d and the one for 20d. Nothing was happening. I watched all videosi doing everything right but still same.
So I have 2 problems as you can see: Screen ghost touching and not be able to hard reset.
Should I send my phone back to warranty?
Thank you.

Hi,
My Note 4 vibration stopped working suddenly without any apparent reason.
I tried a factory reset, reflashing stock rom, still nothing.
I thought the vibration motor has failed so I bought a new motor+power cable and replaced it.
The phone still won't vibrate. Everything else works just fine.
I don't understand what is the issue, haven't found anyone with a similar issue yet.
Any ideas?
No replies? I am kind of stuck without vibration!
you should have taken your sevice to claim warranty in the first place, if not a faulty vibrator, the prob must be in the card

New fingerprint sensors goes for $7 on aliexpress, I bought two to have one spare when it dies again.
Clean flash oos3 I think there's a several level of failure.
Software
Hardware failure because moisture
Hardware completely dead
Try RMA
