Nexus 7 Mistery? - Nexus 7 Q&A, Help & Troubleshooting

Guys, I don't usually post on forums but now I just can't make myself sending it back without making sense of this first.
So I got the Nexus 7 one month ago, barely used it and didn't install any fancy stuff on it. One week ago I saw an app that I wanted and before installing it I had to install BusyBox. In my foolishness I didn't read the description that the tablet has to be rooted before I install it.
When the installation finished this exact problem suddenly happened: youtube.com/watch?v=5d319gUeYLM
Why I'm determined it's a hardware problem:
- The next morning I turned it on and everything was back to normal, however, after 15 seconds it slowly dimmed and got back to that exact screen
- You can navigate the menus and hear the sounds
- The morning after again, back to normal, I hurried and did a factory reset and deleted everything. This didn't help at all, the problem was still there and the screen never went back to normal even for a few seconds.
- It keeps the same lines in the recovery menu and on boot.
While everything points it's a hardware problem and the guy on YouTube said Asus replaced his display, how can this simply be a COINCIDENCE? For this to happen exactly when I installed something it wasn't supposed to be installed if the tablet wasn't rooted?

Strange app locking and radio resets. Anyone else?

This has happened twice in the almost 2 weeks that I've had the phone (most recently today).
I'm on T-Mobile and rooted using the GS3 Toolkit v1.0 and the "ALLINONE [Flash Insecure Boot, CWM, Root phone + Install Busybox]" option. I can't remember if the first time it happened was before or after this, but I think before.
So, most recently, I opened Contacts, scrolled down, opened a contact, then the phone became unresponsive. After a about 5 seconds, the screen briefly went black, back to the home screen, and mobile data was along with cell signal. Those came back up after a couple seconds and everything worked fine. At no point did I receive a popup about an application needing to close.
Anyone else experience anything like this with their GS3 or another phone? Just wondering if I need to get a replacement or just ignore. Or maybe flash a new ROM if it's software and not hardware.

Constant Freezing/Rebooting Nexus 7 (2012)

Ok guys. I don't post often since I can usually find my answers by lurking the forums....but I'm at my wits end here. My 2012 Wi-Fi nexus 7 all of a sudden started acting funny one day. It would freeze u randomly, then reboot, then get stuck in a boot loop for about 10-15 minutes, then boot up, then freeze after about 1-2 minutes of use and repeat the whole process. This was on stock 4.4.2. I've since tried using the toolkit to reflash stock, fix bootloop, unlock and root...all of which I was able to do. None of which helped my issue. Although flashing AOKP DID seem to fix it for about an hour.
Anyway, I gave up on it for about a week and came back to it this morning. Although it wasn't even going to te google boot animation, just stuck on the google logo. So I reflashed stock 4.4.2 again. Now I'm back to square 1. So it boots and will function for maybe about a minute or 2 (or less) before freezing and rebooting.
Is this device shot? I'm out of Google AND ASUS warranty now
I posted something in the big help thread yesterday (probably a mistake). Mine is doing exactly what you describe in terms of working for about 2 minutes before freezing, then rebooting. Mine is 100% stock 4.4.2. Never rooted, unlocked, etc. I have the adb stuff, but I haven't even attempted anything, because it seems so unstable. I don't want a partial flash to screw it up even worse. I feel slightly better knowing that someone else is dealing with exactly the same thing in a similar time frame, so maybe it is a software thing, not a totally dead unit.
Well I may have made some progress. Since the warrenty is up anyway, I decided to crack it open. I noticed the GPU was getting extremely hot for just sitting at the home screen. So I enabled developer options and turned on some monitoring options (the fact that it stayed on long enough to do this is a miracle in itself).
Right now I have some overlay monitoring on including cpu usage and gpu rendering (on screen as lines). I also checked the "stay awake" while charging option. It's been on about 2 minutes so far, although graphics performance is horrible atm. Almost like project butter is disabled and it's running at half power....that could just be the monitoring overlay though. We'll see what happens...
*Update*
It made it 21 minutes, but it did reboot again. On restart, the OS smoothness is back to normal, and it does seem like it goes longer stretches without restarting now, however the issue is obviously still there. I should add that the back cover is currently off. which is starting to make me think this has to do with cooling

Okay....I just admitted defeat with this issue. Just ordered a replacement board for $30 because the resets are still happening. Upon reset, I can actually hear a part of the main board buzzing for about 5 seconds (not the speakers). Not to mention that prior to this issue, I was having a lot of wifi connectivity issues anyway. Hopefully the board arrives before my long bus ride to new york...

Freezing and Crashing

I received my 32G model on Nov 28. Firmware MDA89D. Pure stock unmodified in any way. Not even using screen protection or cases. Setup as a new device, not copy from another existing device. I've been getting randon freezes and crashes. When it froze, it did not respond to any touch input or any key input. The only way to get back is to hold down the power button to do a force reboot. It seemed to have settled over the last few days. What I do have on an ongoing basis is crashes. When I use Google map navigation, the phone will work for a few minutes and the screen went black followed by a reboot. It did it on 2 consecutive days already.
Is it just me having this problem therefore a defective unit or is it the OS / Software problem.

That is strange...I haven't had that kind of behavior on my Nexus 6-works without a problem-never freezes or reboots...now I know the Amazon app would do something to my Nexus 6 I don't know what but when I install it-my phone with reboot randomly or shut down...ever since I uninstalled it-no issues-for months.
Try running safe mode and see if it does it again-that way you will know if it is an app that's causing the issues. This is how it's done: http://www.greenbot.com/article/2923927/how-to-restart-your-android-phone-into-safe-mode.html
You can always try a factory reset as well....have you tried updating to the most recent factory image from Google?

I've been experiencing the black screen freeze frequently since getting the phone only a couple days ago. No other lockups however. Also running pure stock.
I too have the same issue. Screen goes blank and lock ups. Also running pure edition...
Same. Interestingly, in my case, it seemed to happen most frequently when using Hangouts.
I have another post that describes random reboot and I believe they are related. Long story short. I believe either the factory reset + software update fixed it, or it's a hardware problem problem. While I wait for the replacement, I only had one random reboot. Of course the new phone is rock solid. It's only been a couple of days. I would have a few by now if I'm still on original phone _ original firmware.

I'm having the same issue. So no random freeze leading to reboot with ur rma device?

What I'm trying to say is don't panic and RMA your device. Do a factory reset and make sure you're on the latest firmware. Mine was OK after the first self-reboot during setup after factory reset but has been good while waiting for the RMA to arrive. To answer your question, the new device has been perfect but it's only been 48 hours.
I am facing a similar issue with my Nexus 6P, can anyone please help me with it?
On any rom, whatsoever, I get reboot when I turn the Google Maps Navigation On.
After few minutes, phone just reboots
I havent yet tried stock, any idea how can I find the root cause? I have cleared data for maps, also I have tried to uninstall maps with TiBackup and installed fresh from Play Store

Yup same stuff going on over here with mine. It locks up and reboots even after clearing cache and rebooting only a few hours earlier. Have done 2 factory resets and am on the latest OTA update. I also noticed that I have to clear the cached data every day, sometimes multiple times a day to keep device running smoothly. This really concerns me with a device that's less than 2 weeks old. I also have only a handful of basic apps( Fb, YouTube, Spotify). Really thinking about returning it. When the phone runs right its great, but all the issues make me nervous. Might be time for a Note 5? I am just getting used to this phone and would hate to leave it though. Interested to see if the first major marshmallow update fixes these problems.

Mine actually had one random freeze and reboot after factory reset then nothing for 48 hours after that. Of course I rma'd mine and I'm glad I did. Screen is on the colder side with even volume speakers on the second unit. Sending my original one back.

I'm just about ready to RMA. I've tried factory resets, cache wipes and just recently updated to the latest stock MDB08M. It was fine for a day or two but now the lockups are increasing.
As others have said, by any other metric this is one of the best phones I've had. This freeze/reboot thing is getting annoying and even if it isn't happening to every user it's happening to enough to be of some concern.
I'm facing app closures, my gmail app keeps crashing, it happened on my graphite nexus 6p, and now same thing on my frosty 6p. Its not just gmail, it's also chrome now. Maybe i should have not restored from my previous device.
what's this?
I came to this thread expecting a lot more of a technical discussion (the site is called xda DEVELOPERS after all).. but instead all i see is "oh my phone is crashing.. i'm gonna RMA this sucks) posts.. moving on to android enthusiasts on stack exchange thank you very much
upgrading to 6.0.1 fixed it!

screen constantly switching between lockscreen and stock homescreen

Okay, so yesterday I was out with friends and my battery was low.When I had to use my phone, shortly after the battery died.I came home, started charging it and when it had about 20% i turned it on.Ever since that, my phone is constantly switchung between my lockscreen and stock homescreen, with me not being able to do anything(go to the settings or something like that).So I hard reset the phone and when it booted up and I was going through the basics, one message popped up every few seconds: "The UI has stopped working." So it was difficult to go through all that stuff, but I made it only to see the problem is still the same.I also tried to take it apart and blow the dust off the MB hoping it would work, but unsuccesfully.I also have to mention the screen is cracked very bad and you can see inside the phone down where the LG logo is, but the phone was working absolutely fine in that state for over a year.Any help? :crying:
I'm guessing that you didn't have a lot of storage left on your phone, right ? A similar thing once happened to me, rebooted while storage was completely full. Refused to work until I reflashed it.

Random shutdowns and reboots

Hi everybody,
So I have a S7 Edge that I buyed in Spain in December 2016, so it has a year and a half by now.
The phone have the Gorilla Glass a bit broken but the display is perfect aswell as the touch, the back is also broken, main issue there was a corner fall but, this either started nor agraviated the issue in hand, it was no difference between before and after that situation.
The phone was submerged in water, less than a meter for less than 5 minutes, again I dont remember that this issue started nor agraviated the issue.
Now the issue I'm not sure when it started but it was this year for sure, maybe 2 to 3 months ago.
As far as I remember the issue started after a Samsung update, a large update like 1 Gb, the phone restarted to install the Update and during the Update it froze while installing the update in the boot and started heating up I wasnt able to do a thing I wasnt able to either restart it nor shutdown it, so I just waited until the batery run out wich it wasnt much time since it was heating up a lot.
After it shutdown I charged it and then started, it was able to update but from that point I didnt want to either shutdown nor update the phone again being afraid of the phone dying, so some day the phone forced another update, and I encountered the same issue, after that once in a while the phone restarted.
From that point I dont actually remember how it happens if I had some issues but one day the phone restarted and entered a boot loop restarting the phone after a second or two of the Samsung ROM splash, so I tried to shut it down and wasnt able to do so, at some point it "shutdown" but with a red led on and I wasnt able to start it, after 3 to 4 days the light went off (batery run out) and then I charged the phone again but wasnt able to boot up, after a few restart it boot up but then restarted and loop again.
After a few tries I was able to Factory Reset the phone and the phone started functioning kinda alright, I installed an app and while using it the phone restarted so I uninstalled the app, after that the phone didnt shutdown, so I used the phone for some days and never shut it down nor let the batery run out, till one day I updated the apps from the Play Store while updating the apps the phone shutdown again, boot loop and subsecuently shutdown with a blue led this time and not being able to start the phone again, so I waited like before, but for some reason the blue light stayed for like 2 weeks, I guess the phone has a lot of charge and the only thing using the batery was the led I dont know.
After all this I decided that the problem was a Software problem since all the main issues apeared while updating apps, updating the system, using apps, etc, so because I didnt have guaranty I decided to install TWRP and then some custom ROM, so I do it so, I installed TWRP, booted into TWRP, backup EFS, wipe dalvik, cache, data and system, in this process the phone rebooted, boot loop and then again blue led and not being able to start the phone, so I was tired by now and I opened the backpanel breaking quite a bit one side didnt care if I fix this I will change the back and front glass, I detached the batery and the phone shutdown then I was able to start it, boot into recovery TWRP and installed HavocOS this time (I will try with another one just in case), I installed it run it and it appears to be working fine... it rebooted one time and after that nothing I installed Whatsapp a 2.3 gb backup started to download alongside 34 apps from the PlayStore I guess the apps that I had in the previous installation.
While downloading the 34 apps the phone restarted I guess while installing Facebook, after that it shutdowns again after apparently working just fine for an hour or so.
So I decided to install again HavocOS but dont instal any APP but Whatsapp, maps and some other things I need (Keepass, Bank stuff, etc) but from here on the phone started to reboot even in TWRP, while installing the ROM sometimes it freezes sometimes it shutdown sometimes it rebooted and antered boot loop but at least it didnt get stuck anymore I was always able to shutdown and start the phone but with boot loops and shutdowns and totally impossible to use.
So now I'm almost totally sure that it is not a Software (free fix) problem, and now I'm thinking in replacing the batery, the batery is not very expensive (compared to a now phone ofc) but it is a bit expensive for my economy and I'm not totally sure that the batery is the problem, can somebody, with all the information given here tell me something like "I'm at least 90% sure that the problem is the batery"?, cause, I'm a PC Technician that didnt know much about phone but they are practically the same as a PC but less modular and sincerilly I think that it might be the Processor or the Internal Storage, both non-easy-removable and change and both more expensive than a batery and both things that I have to buy outside of my country that may or may not come in 1 to 3 months so, is it really worth buying a batery or this issues point to a direction that the phone is almost imposible to fix with the money I have so its better to save money and buy a new one... thing is in this effing country a new S9 for example cost 1000 u$s and my salary is 600 u$s so its a bit anoying to save for something like that, even a new S7 Edge is worth 600 u$s here, and thats what I paid in Spain one and a half year ago when it was the latest Samsung phone available.
Sorry for the long post I wanted to explain everything throughly and I hope my english is ok.
Best regards.
