4.2.2 + magnetic cover = rebbot everytime i flip cover - Nexus 7 Q&A, Help & Troubleshooting

Hey everyone,
So ever since I have updated to 4.2.2 CM nightlies, i began to get this weird and super annoying issue:
every time open or close my magnetic cover on my Nexus 7 which is supposed to turn on or off, but instead my tablet just reboot!
So does anyone have any similar issue?
Any ideas about how i can solve this wretched problem? :crying:

My nexus 7 used to reboot on its own all the time too. I thought it was my magnetic cover, but then I realized that my power button was stuck about halfway pushed in. That kept waking the screen all the time too. I ended up just taking off the back cover and fiddling with the power button. When I put the cover back on it worked great. So that may be the issue with yours possibly.
I would suggest taking your nexus 7 out of your magnetic cover for a day or two and see if you still experience the same problems. Also check in your battery settings to see if your screen turns off and on on its own a lot. And if the device keeps waking up more than you would anticipate.

[Q] VERY weird N10/4.2 bug!

So, I am now on my 5th N10 (FFS), and my latest replacement appears to have a very strange bug. This has happened to me twice in the last 24 hours.
The bug is this: On (occasionally) rotating the device, the N10 turns 'off' and crashes to the lock screen. The lock screen cannot then be exited. Swiping to unlock just re-crashes to the lock screen, as does swiping one of the top panel menus (e.g. trying to go into settings etc.). Rebooting the device also fails to sort it out. To get back past the lock screen (I discovered this by accident), I have to disable the wifi (e.g. put it into airplane mode). After that it's fine.
Haven't yet tried a factory reset. If it happens again I'll take a short video.
Anyone else seen this?
Are you using any covers on your tablet?
I use one on mine which have a magnet for locking, and one of its features is auto locking/unlocking the tab when you open/close the cover.
It could be that it gets activated when you fold the cover on the backside.

I am, and that has crossed my mind. If it happens again I'll take the cover off and see if that does anything. Strange, though, that of the two times it has happened I was unable to get past the lock screen until the wifi went off, then it was instant. Been using this cover for a couple of months now though, and this has never happened before.
*EDIT* Just tested the old Nexus (not yet sent it back) by laying it flat on the case and it replicates the problem. So looks like magnets to me. Very odd that it should happen with this case though. Never happened before.

[Q] Bottom half of screen not responding to touch

I had an exam and removed the battery for my phone for the duration. When I put it back in, the bottom half of my screen stopped responding to touch. The screen itself is unharmed and uncracked. The S Pen still works flawlessly. However, the bottom half of the screen ("above" about 890 pixels on the Y axis) simply does not respond to normal touch. In addition, the volume buttons no longer change my notification volume. They still work for music volume, just not touch volume. When I long-press the power button, the power menu sits at the very top of the screen and has black covering the whole bottom of the screen for some reason. When I receive calls, the buttons are right at the top. Because of this, this seems to be some sort of software issue, but I have no idea what would cause it. Has anyone with more experience with Samsung devices seen this before? Multiple restarts and battery pulls have done nothing.
EDIT: In case anyone else encounters this, it had something to do with my case. I think my phone thought it was a smart cover for some reason. I enabled and disabled smart cover and then removed and replaced the case. It's working fine now.
EDIT: Never mind, that was a coincidence. The issue is DEFINITELY that the phone thinks it has a smart cover on it, but it has nothing to do with my own case.

I've had much the same problem. While the S-Pen was able to make selections that the touchscreen wouldn't, other S-Pen functions such as Air Command and being able to start an Action Memo wouldn't work. Waiting for an extended period of time (like 24 hours) and all of a sudden it started working again. However, while I was waiting, rebooting - even performing a factory reset - didn't' fix it! I just now rebooted it and it's not working again, and it's not in a case.
Where do you find the option to enable and disable Smart Cover? On the Note 2, it was (apparently) under Security / Device Administrators, but I don't find it there. The only option I could find was in Accessories / S View Cover / Automatic Unlock but changing this setting (including rebooting between settings) hasn't solved it.

Sadly, it was just coincidence that it randomly stopped happening when I enabled and disabled the auto-unlock feature with Smart Cover. My phone started doing it again and I've been unable to repair it. I went to Verizon and they wiped my phone before telling me I'll just have to get it replaced with a refurbished one. Very frustrated. Shame there aren't any AOSP based ROMs yet (like CyanogenMod)-- they'd probably fix it since the cover thing wouldn't be a feature.
Bump.
Anyone know of the APK which would handle S View Cover behavior? If we were to disable that I imagine the problem would go away. I'm still not totally sure of the origin of the issue, but it seems to come from a combination of hardware and software problems. The hardware sensor thinks I have the case on, so the software changes things around. When I call people, I get the S View Cover style call screen. If I change the toggle in accessory settings to automatically unlock the phone when opening the cover, hitting the lock button automatically unlocks the phone as though I had no lockscreen. However, when this is disabled, the lock screen is NOT in the S View Cover form-- it looks stock. This confuses me.
Any ideas from anyone else getting the issue?
Same experience
Just to add my experience as I go. This afternoon I received an error that my SMS data could not be downloaded. Upon sliding down the notifications I was unable to control much. I ripped the majority of my hair out over this.... My pen works flawlessly everywhere though. I eventually discovered it works fine on the bottom half as you described. I have to run to some appointments, but I'll touch back after I try a few things.

Maybe it was caused by the battery insertion or backplate replacement. Perhaps too much pressure or an uneven pressure damaged the circuitry, which is now loose and causing the intermittent error.
Or perhaps it was a static discharge from the battery.
Both cases seem to me to be warrenty items.

Uh oh... I'm rooted and on Verizon. There isn't a way to unroot yet is there?

I thought the only thing necessary to unroot is to flash the stock ROM. The download is linked from the de la Vega post.

I realized had about 3 days left on my Best Buy (elite+) 45 day return. Swapped for a brand new one :good: with no issues!

I have the same issue. I ve been trying to understand why this happened but no luck. I tried everything from updating to reseting. I first noticed it when i took the battery out as well. but the problem kinda fixed it self so i thought the phone has a spaz or something. but when i removed the battery again it happened again.
I took it to the people i bought it from and all they can say is cause there were a couple of scratches on the side of the case that it may not fall under warranty...
i was pretty angry cause its only two months old and the warranty is for a year. and the problem started happening while i was overseas so its been like that for almost a month. hopefully the sales guy is just talk cause its not up to him its just his "opinion" as he put it.
Did they explain to you why this happened? or if this is a common issue?
Hope your new phone is ok
I have this problem intermittently also. Exactly as described above.

any updates on this? im having the same problem now with my tmobile version. it fell facedown and the extended battery i had it in fell out. im going to try putting an aosp rom on it when i get home from work.
Timely post! I gave up. Verizon sending me a warranty replacement to arrive today.

I have the solution!
Please. Let me know it worked for you, so people that doesn´t like to post and only read can solve this problem.
The Problem:
The half bottom screen is not working. Including the back button, the option button and the home buttom. they only work if you use the S Pen. Except for the home button. The volumes button do not work either. So the Solution is this..
take off the battery while the phone is on. YES, do not turn off the telephone and the take off the battery. Just take off the battery while the phone is on. It should work. I hope this is the solution.
One more thing. Do not allow your phone to dried up the battery completly so this wont happen again. It is better to turn it off before it dries up.!
Please let me know if it worked for you! I will let you know if this problems start again and if was only an coincidence.Hopes it not!
This tough me a good lesson! never buy a Phone from not trusted retailer, it is better to pay the full price a good store. The people that sold me the phone has a crappy warrraty like if the screen it cellphone is complete off they wont allow me to use the warranty and my phone had faulty battery conecction so it was off. then I paid 100 dollars to be repaired then this problem.
Ok, guys please let us know if it worked so people start saving their phone
Just happened to mine as well
Hard reset didn't work, on the phone with support trying to request a replacement now.
Finally Solved!

I haven't gone back to refresh my memory but it seems to me that all these occurrances were caused by removing the back cover. Try removing it and the battery and firmly press on every spot with your thumb. First place the device face down on table padded with a single layer of a blanket. Remove the SIM and SD card and firmly reinsert. Press the back cover on and try it, then return it for warranty if it is still bad.

I also was faced with this issue today at the start of my morning BUT I FOUND A SOLUTION
I have a Sprint Galaxy Note 3 N900P Stock ROM/ no root, no mods/custom kernels/boots etc...
My device side effects were
The bottom half of my screen was not responding to my fingers,
When you press the Power Button, The options appeared on the top section of the screen instead of being the center
When I press the volume up/down keys, The volume would raise and lower, But the screen that pops up and shows you the volume had increased or decreased didnt show up
Only way to use device was with S Pen
Basically all the issues everyone listed, I had them.
Now my solution; if the issue is a hardware issue.
After dissembling my phone to see what each hardware part of the phone controls, I've come to the conclusion that there was an issue with my USB Dock Connector section of the phone. I uploaded a image pointing which connector controls it. I tried to just wipe and clean it up a bit because mines had some residue on the underneath of it. Then I plugged it back in and it started back to work %100. After I tried restarting it a few times and shaking the device up, it still works; Although I am still going to order a replacement USB Charging Port with flex cable just in case.
fixed.
This is the definitely the hardware problem.
most likely happen if u ever dropped ur phone to the ground ----------- and reboot ur phone some what later time. (can be days or months).
Temp Solution to this problem is...
face down your phone to the flat floor or a table, gently hit the back, strong enough to shock the devide, but not that strong to crack your screen.
one other simple way is to drop your phone to the floor, screen is facing down, from about 30 cm high from the floor.
"simply, hit your device like you used to fix your ur old TV. "
that is just a temp. GL.

[Q] Nexus 7 Grouper Screen Constantly Turning Off

My Nexus 7 2012 Grouper running Android KitKat 4.4 stock is constantly locking/turning the screen off as soon as I unlock/wake it. I did some searching and after some troubleshooting I finally singled out the problem - it is the case.
Granted it is a cheap case and so is nothing fancy, just a hard plastic back with a flap to cover the front of the device which secures to the back via a magnetic strip. Unfortunately I do not have an extra case to test with and find out if it is exclusive to my case only. My question is, does anyone know if this an isolated incident or is it a common problem regardless of the brand of the case?
Also, I assume this has something to do with the magnetometer, accelerometer, and/or gyroscope and the case interacting with them in some way resulting in the device being sent back to sleep. So is there anyway around this, i.e. is there any way to turn this feature off so that the device cannot be put to sleep in this way?
Thanks in advance and appreciate the help troubleshooting.
[Solved] I figured out that it was the magnetic flap causing the issue. It is designed so that the flap shuts off the display when closed but since I was folding the front cover, which has the magnetic flap on it, around to the back when using it, it was triggering the screen off.

[Q] Black Screen w/ Time at top of screen?

more and more often my wife's S4 will turn into a black screen with the time at the top of screen...this will happen at random times she says, checking texts or looking at gallery pic's.
she has a generic phone case with a magnet to close the full cover (not a windowed cover.) BUT, like me, she leaves this full cover open (bent backwards and the magnet holds it that way) ALL of the time. i'm thinking the phone decides to go into Sview mode or something?? is there a way i can turn this feature off, or fix this problem another way??
BTW, she is running Android 4.4.4
thanks for any insight! --- art
bump?
Seems like you should be able to turn it off somehow. However, it might be a software issue in the case a data factory reset should fix it. If it's a hardware issue then I would take it to my provider or Best Buy to look at it.
i removed the case yesterday and it hasn't happened ... yet! hopefully that fixed it. thanks for the reply Stoney!

Screen shows noise momentarily

Hi!
Bought a sweet Nexus 4 just recently, only to drop it from a 5 drawer high cupboard a few days later. Fell straight down on the right side, damaging the whole front unit. Sent it in for repairs. got it fixed; checked it and took it home.
Didn't notice it at first, but when I turn the phone on; as in wake it up to use it, the screen flashes momentarily (1-2) showing noise just like a tv with no reception. Went back the next day, asked the repair guy to fix it but the wacko said no guarantee . Can this be fixed or am I doomed to use this phone with this annoying flaw? The touch panel and everything is working as expected but this whole noise thing is breaking the whole experience for me. The screen turns on just fine when powering it on, this happens only when I wake it up to use it. Tried resetting the phone but to no avail. Running latest version Lollipop; 5.1.1; Kernel version 3.40.0 Wed July 8 Build Number LMY48I
As a side note, the phone did not have the screen flash problem before I dropped it. Used it for a good 5 days before I broke it.
Would love any help to fix the phone, i really love as I have the nexus 7 LTE version as well!
