Hello, i just bought a nexus 10 and updated to android 4.4.4 but i noticed a weird thing that happen often when i power on the tablet. Before the google logo in the lower side of the screen im having strange artifacts / lines with strange pixels that disappears in an instant. I have recorded the thing and uploaded a video....tablet is stock locked and unrooted. Tablet works normally without any evident issues....why im seeing this artifacts before the google logo and how can i fix it? It is software or hardware related? Thank you very much i hope someone can help me here is the video :

I have noticed that on both 4.3 and 4.4. Wasn't there on 4.2.
Im not sure if the issue was there before updating since i just updated the tablet by ota to the last 4.4.4 as soon i get it. I tried a clean flash from stock and the artifacts on boot are still there...i cant flash other custom roms because im stock and locked....more infos are appreciated I would like to know if its normal and if its hardware or software issue
Thank you very much

Mine has always had that as well. I don't think it's that big of a deal since they disappear right away. Possibly a combination of hardware and software. Maybe due to the Mali GPU chip? I wouldn't worry about it if I were you. Seems to be pretty common on this device. Now if they don't disappear, then that's a problem.

Yes the artifacts disappear after the google logo. This thing happen only with the stock rom or even with custom roms? Unfortunately i cant try since its a gift, i hope this artifacts are not sign of a hardware defect.

I was using SlimBean 4.2.2 correctly, but updating to SlimKat 4.4 this problem appeared, but I also updated TWRP from 2.6.3.0 to 2.7.10.
Same problem with others ROMS as Purity and RastaKat and different kernels as KTManta and Trinity.
Are you using TWRP or CWM?

Thanks for sharing your experience. Im using the stock recovery since my nexus 10 its stock locked and unrooted. So every nexus 10 owner who updated to kitkat would experience this thing...This issue has been reported to google? My retailer told me that i can RMA the device but if every Nexus 10 have this artifacts at boot then its useless to RMA.…also im new to the Nexus 10 forum as i own a nexus 7. This problem has been mentioned on other topics? Thank you

Ok, then this must be a problem with Google's sources (a GPU driver error?) because it is a common issue between different ROMs, Kernels and recoveries, but I do not know if Google has been notified.

Chrome seems laggier than it should be, hope there is some issue there than can be fixed to improve performance.
Every Nexus 7 I've had so far (that'd be 4) have all had washed out looking greens and yellows and over saturated whites. Hoping that is something a patch can fix.
Tegra 3's Prism smart dimmer feature causes the screen to look over exposed while and after videos play (fades away after a few seconds). I've disabled the smart dimmer, so it's okay for me, but seems like an issue that needs a patch.
I have seen nothing in JB 4.1.1 that would require an update at this point.
Might as well expect an update for dark pixels.

Screen flickering is a known hardware issue
Mine lags bad from time to time. I wonder if it has to do with google now because my galaxy nexus lags just as bad if not worse when i tap the google now search bar. I was trying to find and app (shazam) and thought it would be faster to look for it through now, but it lagged and lagged and lagged. By the time I got the app open, the song was over and I couldn't tag it.
My Gnexus is great, fast ,no complains at all,Google now is quick I got no lag, but on the nexus 7 it becomes a problem to the point that I have to switch it off and use the browser.

I use dropbox which is pretty much the same in terms of resources. I have play movies, music, currents, books. I have pandora on there, google now, generally everything you could need. I've done this on both stock 4.1.1 and on Paranoid Android (every iteration). Literally NO lag. Even being slightly underclocked.

Nope, it's from a poorly soldered wifi chip, that is drawing power away from the screen when wifi is low.
I had this issue, and called Google personally for support, and the person confirmed that the screen flickering was hardware, not software.

Never had any of that so I doubt its a "software issue". If it is its likely something you installed.
quick update about the lag on the nexus7:
i used Nexus Root Toolkit v1.5.2 to root and install recovery about 4 times ,and in all this times i had problems with lag ,so two days ago i decided to restart again and root the n7 with Galaxy Nexus ToolKit v2.0 but without installing the custom recovery.
now it very quick and as no lag at all,and yes i loaded the identical apps all the previous time.
ideas???

I think most of the lag is because of a bad app or a setting somewhere. Glad to hear you got it sorted out. I'm just looking forward to the update that fixes the bootloader issues with accessing recovery without the usb cable or using terminal commands/adb/apps.
Hey all,
As the title says: I'm having random reboots while using the camera. First it freezes for about 3 seconds and then hot boots into the Nexus logo. It happened 3 times over the past month so it isn't bad, but still not as it should. I'm on unrooted stock.
Any experiences/tips?

Have you tried re-flashing the stock ROM? It would be worth a try.

I had this problem on a DHD. Althought this is not a dhd the problem might be the same.
That was battery related. When i changed the bad battery, my problems went away.
Usually if your phone reboots during camera shots, it means the battery is borked. RMA it man.
Is it confirmed battery related?

Who knows... I got it as well, I notice it happens while focusing with flash and/or taking photos with flash for long time then it got reboot (http://forum.xda-developers.com/showthread.php?p=46312752) got it on stock camera app, with camera 360 tried the same situation and no reboot at all...
Maybe the flash warm the cpu or something which cause the reset...my battery temperature seems fine as I monitoring it.

Hi, Do you have a custom recovery installed? Reason Im asking is because I have difficulties to reproduce the problem after flashing a 4.3 factory image.
Edit: Im not sure what kind of impact a custom recovery could have. I have reproduced the issue on cm 10.1.3, Cm 10.2 and a stock rom flashed via cwm. But as I said, I have problems to reproduce it after flashing 4.3 factory image.

No mate, I'm on stock clean (without root/open bootloader) as it comes from google play 4.2.2 (I even didn't update to 4.3 just to check the stability of this version).
Now I got it again, I can confirm its nothing to do with 'heat' or anything about hot cpu...the device was cold. At this time also wifi was off so if someone had a thought...its nothing to do with it.
Seems its some bug with the stock camera app and/or gallery app... Shots only 2 photos with flash, take a look at the gallery and it got freeze and reboot.
Maybe the option to move from gallery to camera with only swiping...donno... Anyway its happening only when flash on so its weird....
Do you got this reboot only with macro flash photos or any type of flash photos?
Again, tried camera360 with more flash shots at macro and seems works without any problems , also Ive found it more accurate then stock one, eventough I like the stock app.
Has anyone found the problem cause I'm also having this same problem. Its happened three times, two of the times it was when focusing with flash. The phone just froze and rebooted. I did notice that before it rebooted I heard the camera aperture shutter a few time really quick and the the phone rebooted. The other time it was when I went from camera to gallery and zoomed in on the picture I had just taken.
I maybe thought it was the ROM problem but to hear you say its happened to you on stock ROM and not rooted my not sure what it is. If it matters I was on AOKP 4.2.2 and cm10.1.2 ,cm10.13.

I had a nexus 7 and Asus transformer tf300 and a sold them to buy the nexus 10, nice tablet but this is getting annoying with apps crashing all the time and I did not have that problem with the other ones. I bought this one las Sunday and came with 4.2.2 so my question is a software or hardware problem? I have been looking around and applying different solutions but nothing.

you can make restarts ocure more rarely using one of this variants but they still remains .
try a custom rom also . mr robinsons for example
if the problem persist ... get it back and forget nexus 10

Thanks for quick reply
Same problem here.
I've had the same problem too. All was working fine for around a month, but now I'm finding that apps will crash for no reason. It doesn't have to be when they're being "touched", they'll sometimes just self-destruct with no prompting from myself. A reboot seems to fix it for a while, but the problem seems to come back. Anyone found a solution to this? I'm not keen to install a custom rom as that shouldn't be necessary!
nexus 10 crashing
The same for me, everyday i have to restart it, apps keep crashing all day. I think its the ekynos, my galaxy nexus doesnt behave in that way and i have more apps installed.
I think the problem is related to memory leak. When the apps starts to crash the free memory is running really low, sometimes even below 50mb and all background services are restarting and being killed by system over and over again. A system reboot can fix this until the free memory running low again. Aokp and some other custom roms alleviated this problem, but no one fix it. Maybe Android 4.3 or 5.0 might fix this.

Basically, my N7's screen is frequently unresponsive. I was trying to start something in my launcher, and tried pressing it at least 6 times, but nothing happened. Then I tried swiping between launcher pages, and that worked just fine the first time.
This just started happening on an almost constant basis within the last 30-60 minutes, and I was wondering if anyone else has experienced this, or heard of anyone else experiencing it. I'm running the latest Minimus with Jassy's latest kernel (I just flashed them this morning, but it was probably 4-5 hours ago at least), with the DPI set to 290 (I just raised it from 280 to see if that would help anything). I also cleared the cache and dalvik.
Any ideas?

It happened to me as well (complete stock). Mostly (if not all) instances were with Chrome. I don't remember it happening again since I switched to Chrome beta. (Fingers crossed).
I just took mine back to Best Buy and exchanged it for the 32gb model. The guy at the store asked if anything was wrong with the tablet and I told him that it would freeze up and I would have to reboot in order to fix it. He told me that all tablets and phones freeze like that and that I should reboot the device at least once a day to prevent the freezing of the screen. I thanked him and told him that I would do that. These salesmen must think that everyone is as dumb as they are.
I hope my new tablet doesn't have the same problem, because if it does I might give up on the new nexus 7.

So I had pacman v22.0.0, and I used survival mode on superSU pro to keep root, and flashed the pacman 4.3 update. My phone started lagging, overheating, and taking forever to charge. On 4.2.2 I had a few apps always running but rarely used more than 800MB of my RAM, but oh 4.3 with all the apps running the same, my RAM usage is normally about 1.4GB.
I'm assuming this has to be 4.3 right? Is it just me that's missing something, or have other people had the same experience with this?
Either way, if you're not completely running out of free ram, you have nothing to worry about.
Nope its not an issue with 4.3. I have few apps running with 800mb used . I am using PA 4.3. Never noticed any lag or overheating problems. It could be certain apps causing the issue?
Sent from my Nexus 4 using Tapatalk 4
Why don't you check in Running apps to see what apps are taking up your rams. I have been using 4.3 custom and now stock and its usually 400mb or less.
I assumed it was the fact that the pacman ROM had so many customizable options. I have the same exact apps running as I did before I updated, but my RAM usage has almost doubled. I know I have nothing to worry about, but when my phone is hitting 120 degrees on average, lagging, and the battery still drains while it's on the charger, I figured it's either the ROM or the fact that I didn't re root, I used survival mode. I checked my app usage, but the apps aren't accounting for most of the usage. Something else is, and I have no idea what.
With stock Rom and sometimes I can see 450mb Ram available.
So what?
Phone runs still flawlessly with no lags.

Guess it's rather the overheating and lagging that upsets him
You probably know this already, but it's not because of 4.3. Never had anything like that on PACman or CM10.2 - only once with a different kernel while navigating. But it just overheated, didn't lag or anything.
You should have flashed the factory images instead of just the zip;

You obviously misinterpreted him. I guess he was trying to help by comparing to his situation. Maybe he just didn't understand completely what your real problem was, but I doubt that he tried to birch you
But as was mentioned here before you should probably flash latest bootloader and modem. Either by flashing the factory image or by flashing a zip that contains both bootloader and modem.

Didn't need to change the ROM or kernel, I figured out the RAM bar was showing me running, AND cached processes together. There's actually only about 400mb of running processes. All the other stuff was cached. Didn't notice it till way later.
