Background/Insight
After finally becoming fed up waiting for the OTA update to reach my device, I decided it was about time I manually update my Nexus 7 (2012) through ADB. While everything appeared to install perfectly (followed these guides: Guide1 & Guide2) I noticed one odd quirk after rebooting... A hideous white flash occurs right before the boot animation plays. To most it probably isn't a big deal, but to my OCD and I it is a huge deal (not really, but it is a little annoying).
The Question
Now, all that being said, has anybody else experienced a similar issue with their Nexus 7 (2012)? If so, were you able remedy it? Any input is greatly appreciated!
Here's a video I took of it: https://db.tt/byTVcr1i
Also, here's someone I found on YouTube who has a similar after having upgraded to KitKat: http://www.youtube.com/watch?v=-XaL0E0JMJo
Yes. Don't worry, from observation I have determined that is a copy of the last on screen image of the system recovery

Alright, I am currently on my third Nexus 7 and getting a little frustrated. I really love this device and would love to customize it the way I want but I hold back just in case I have to return another one. My question is, is anyone else experiencing problems with their tablet randomly freezing? I havent seen any forums discussing this particular problem. I have a hunch it could be the Facebook app that is causing this but that is just a theory. Below is a video of said freezing problems. Sorry for the quality; it was late, i was drinking and enjoying Netflix.
Not that I've heard of, but a quick forum search would easily confirm or deny this.
Edit reason: added detail.

If your anything like me I'm constantly force stopping apps because why should they still be running of I'm not using it, right? Well I was having the same issue as you. Freezing and studdering on a quad core CPU. Mainly it was freezing in the settings menu. So I stopped force closing all these apps I usually do and the freezing stopped. I'm on about a week in with my 3rd nexus 7 and not one freeze. So if you do do as I do try just letting the apps be and "kill" them instead.

The way android is designed, apps are supposed to run in the background. Your not supposed to have a lot of free ram. 100 mb of free ram is the same as 5 mb... If it's free ram it isn't doing anything but being wasted just sitting there. Task killers are useless since eclair 2.1.the reason apps run the in the background is so you can open an app where you last left off. Among lots of other reasons. Let android manage the tasks it's really good at it.

I've had a few freezing issues on my nexus 7. I've only had it a couple of days. It becomes completely unresponsive for minutes and never recovers. I have to hold down the power button until it shuts off (20 seconds maybe).
I've had a number of other quirks that really show (to me) that you get what you pay for. Its a cheap tablet with a top end CPU/GPU, but that's about it.
Not sure what my next step is, but I doubt I would be happy with the shortcomings of the Nexus 7 even if I had a perfect device. I think I just like higher end devices is all, and I don't mind paying more for something that just works with no compromise.
Again just my opinion.

No such problems here, but if I were you I would use the Linux command line commands : top, ps, free, df. With those you should be able to find out if an app or process is misbehaving. You need to install the terminalIDE app and read about those commands.

Freezing issues
I just purchsed one... Used it for 2 days. After using for a while I consistantly had freezing, particularly when typing. I called it in for a RMA refund. Don't know what the issue is, but moving on to something more tried and true.

Freezing - yes now and then...
My Nexus 7 freezes occasionally. I have noticed that when it restarts there's a bunch of updates. Me thinks that maybe the CPU was busy doing updates while I was keying in / touching the screen etc and couldn't cope...but maybe not. These apps seem to update a lot, same goes for my notso :silly: smartphone.
Anybody else come back to your Nexus 7 that is actually completely off and requires a power button and volume down hold in order to restart? Also I find the Android OS is consuming much of the battery in some instances.

Bought my N7 three days ago and it worked brilliantly after installing all my apps from the play store then I got the message to update the OS from 4.2 to 4.2.1 which I duly obliged. Thereafter it was a totally different device with crazy stuttering just swiping home screens and and solid freezes on chrome which was especially bad. I had to do at least half dozen soft re sets when everything ground to a halt and a factory wipe none of which helped. I spent this afternoon using the nexus toolkit to unlock+root my N7 and installed nightly CyanogenMod 10.1 with jb20121212 Gapps and individually reinstalled+tested every app from play store including Chrome. Its (thankfully) now buttery smooth again and I've not had any problems whatsoever in the past 8 hours of using it. This surprised me as CM10.1 is based on 4.2.1 and maybe suggests its a problem with the stock Gapps included in the OTA?
I love android but Google are releasing these updates before they're ready and it makes the OS look unreliable in the eyes of the average consumer who has no interest in rooting and flashing roms.

I bought my wife a first generation Nexus 7 about 2 years ago and everything was fine with the tablet and is now updated with stock 4.4.4. Recently she started noticing that it would freeze for no reason and finally it got to the point where it would freeze very soon after it was booted up. I cleaned the cache and factory reset but the problem persisted. Obviously the unit is out of warranty but I called Asus to see if they could offer any advice. The only answers I got was that they couldn't do anything and it sounded like there was a problem with the motherboard. They also told me I could sent the tablet in for repairs but it would probably cost around $200! After laughing out loud at this ridiculous amount I told them I'd just go buy a Samsung Tab 4 for my wife and forget the Nexus. I bought the 8 inch Tab 4 and my wife is happy with the functioning of the product. BUT, I decided to give the Nexus 7 another chance at life so I utilized the Nexus Root Toolkit and I kept the stock 4.4.4 ROM instead of going the custom ROM route. I am pleased to report that there was NO motherboard problem and this tablet is working great so I am now the proud owner of the Nexus 7.
3year later. Still the same on 5.0.2
I really want to break this tablet on someones head who made it.
After 5.02 ...
It slowed down substantially. I did the "clear cache" which helped a little. It's so slow web browsing that I may as well not even try ... often 15 seconds to a minute to respond to a link click.
SO ... use it mostly for the Kindle app. I don't think it is the app fault, but when it locks up now, I see nothing on the screen; finally determined that it was in the process of downloading an update to some app or another, and the downloading locks the system if the kindle app is on the screen ... and seems to be a major slowdown other times.
Maybe there will be a 5.03 getting the performance back to KitKat levels.
Hey! I thought that I had a flawless Nexus 7. That wasn't true!
I played Puddle THD for 30 minutes and back in the homescreen my screen wasn't detecting where I touched.
(Like in this video: http://www.youtube.com/watch?v=Gh4FMM7ctVo )
This is very frustating since I worked hard to get this tablet. I am running Stock firmware but I'm unlocked/rooted. I was wondering if there was a fix or if this problem is present in every tablet. Thanks.
Mine has been perfect so far. Mine is still stock jellybean though.

The issue in the video seems to be the same one being discussed in this thread:
http://forum.xda-developers.com/showthread.php?t=1789450
Although a few of the people in the thread will start calling you a crybaby for even thinking that this is a problem.
Hello hope in right place, getting problems with n7 after doing the up date to 4.2.2, keeps lagging, going slow, sometime freezes! Also just noticed still got the last year kernel on device, I did do the frame work way to update and not sure if that's caused the problem? I've done a reboot and still does the same, just wondering if anyone could help please?

I've heard the device will do things like restart randomly, and have some other misc issues - is that fixed with later releases of it or is it still an issue?
I never got any og those problems with my N10, maybe others do i dont know. Mine runs very well and the best tablet i have used

My N10 suffers from random reboots and memory leaks every couple days. But after flashing a 4.3 rom those problems almost dissapear with the updated Mali drivers from Samsung
So right now its a no issue, at least for me
Had screen flicker, but went away with the kit kat update (fingers still crossed).
Only had one reboot and that was on 4.3.

I've been using mine for almost over a week. It came with 4.2.x and asked for update to 4.3 right after unpacking. Never had a single problem for a week with 4.3 and now using 4.4 which i manually updated. Still had no problems.
No problems here too..
The reason that you maybe find much 'complains' is because people with a problem are searching for a fix. But hou never hear a word from people without problems.. Well until now
I really love this tablet. Fast and oh te screen.

On 4.3 I got
- screen flickering
- random reboots after heavy apps (like reading big sized PDF in acrobat)
After 4.4 I haven't seen those issues yet.

I've not had too many issues with my N10. I've mostly been running CM10.2 on it, but I've put KitKat on it now and it's purring like a happy cat.
Solid with 4.4 so far.
4.3 eliminated a number of the screen issues with the updated Mali drivers. Looks like they were updated further under 4.4 as the Google site shows new binaries for 4.4.
I'm running stock 4.4 and have 0 issues. Didn't with 4.3 either. Can't say for anything earlier, I'm newer to the device.
Still running 4.3 here, but mine reboots randomly a couple of times a week.
Waiting to see what 4.4 will do.

I had massive problems before, but it works like a charm since 4.4!

4.4 seems so far (over two days uptime with Chrome installed!) to have fixed the massive memory leaks on this device.. 4.3 never seemed to release memory correctly and SystemUI would bloat to 200MB and completely implode on itself. Now it seems memory is releasing fine, and SystemUI is fluctuating in memory usage like it should be now..
I was given an N10 for my bday back on Sept 30 and its gotten almost daily use. I can say with full confidence that I have experienced ZERO problems. No memory leaks (if its going on I cant tell...the performance is snappy as hell!) no light bleed and definitely no random reboots. I have thrown the most hardware intensive games at it and they all work better than I had hoped for. It does exactly what I want it to do when I want it to do it.
I've had it for about half a year and used daily and I've had one or two reboots during that time, quite long ago now, otherwise it's been perfectly smooth and had no issues.
The photo editor crashes while editing large images (probably runs out of memory), haven't tried it on 4.4. But that's really not a issue as I normally use Photoshop on my pc anyway.
So far I never had any other issues at all, no random reboots or anything else. 4.3 was running smoothly as is 4.4 which I have now. The only modifications I have made are rooting it so I can use certain apps, and I didn't even have to reroot after the 4.4 ota.
tldr: mine works like a charm.

Mine suffers extremely bad with memory leaks and random reboots when I have Location Services on. If I turn Location off, it doesn't reboot but after 30 hours or so, it slows to a complete crawl and redraws the launcher every 2 seconds thus making me have to manually reboot it. It's usable and I still use it every day, but I'm definitely not ecstatic with it and I'll likely replace it as soon as another tablet running stock Android and with a beautiful screen comes along. Hopefully I'm not waiting too long.
I get a reboot on average every 3 days. Usually while in the browser.. Screen will just flash white and reboots.. Never slows down before had.. No sign of trouble either..

I haven't had any reboots from the browser yet, but I did get a hard freeze while using the HBO app yesterday. That's actually new, never saw it before the update so hopefully it's just a one time thing.

I'm having problems with any rom later than 4.2. The 4.3 roms cause random reboots, and 4.4 will not install.... Something about some E: error.
I've gotten into the habit of wiping for factory reset before every flash.....so I have no idea why the problem with flashing the 4.4 roms. :silly:
I just updated my 2012 nexus 7 to 4.4.2 and I am having issues with little pixel looking artifacts appearing when rotating the screen and when switching users. Is anyone else having this issue?

I had the same after OTA, however, after I did factory image load (without wiping userdata) it went away. KOT49H Nakasi ..Used the bootloader 4.23 from jwr66v via XDA ..not saying this is a cure....but it's gone.
I had a similar issue when KitKat first came out. I wanted it so bad and it was only for the N5. I downloaded AOSP and built it, but didn't have the "official" proprietary drivers so I figured that was the issue.
Still haven't changed it, probably gonna flash Purity or PA tonight.
I cannot use my bluetooth headset anymore for skype & viber calls it has crazy sound after kit kat update.
anybody have a solution for this? Please help.

I've got this also and the weird pinkish flash when booting up. Seen quite a few other people reporting the same issues even after wiping and starting from scratch. Maybe not major issues but still annoying glitches that should be sorted.
