One totally dead Nexus 9 - Nexus 9 Q&A, Help & Troubleshooting

During last Friday and Saturday, my Nexus 9 started locking up. Initially it would just freeze, and reboot. No excessive heat, just general use, browsing on Chrome. As the day went on, the freezes became more regular. In addition, freezes would come with small grey rectangle graphical artifacts.
At this point i left it for a while. Coming back to it, it started locking up again - once during boot.
Again I left it, this time over night. Sunday I did a factory reset.
It made it maybe 10 minutes into the reset before, again during Chrome or Bacon Reader, it locked up. This time it locked up with animated grey rectangles, and very loud white noise.
It's not come back on, so I'm now waiting for Google to replace, hopefully before Christmas.
For reference, S/N was HT4AF, day of release model, black, UK.

Make it two. Mine just died. No warning. Just cold dead. Thanks Santa.

Make it three. Got the tablet for my son. He was setting it up and there was a loud whit noise,then
a white screen. Then finally nothing.
I have one very upset child.

HTC quality.

Mine now freezes with white screen and loud noise multiple times a week. Holding power will reboot but a few seconds in to real racing 3 it will do it again. This is supposed to be a flagship tablet but I'm not impressed already having returned one that had a stuck gyro. The one I returned had a much better screen than this one too. No light bleed. HTC are no help in Australia so I'm screwed

Screen went completely red upon waking

About a week ago I had just checked an email using the gmail app and put the phone to sleep. I then remembered I needed to do something else on my phone, so I woke it back up. Upon waking, the entire screen was red, I could see the background still, but there was noticeable artifacing at the top of the screen. I unlocked the phone, and it was still the same. I could use the phone as normal, but the entire screen was a translucent red. I put the phone to sleep and woke it back up and everything was back to normal.
I am still in my 30 days of ownership, so I was wondering if anyone thinks this was a one time bug or if there is a deeper problem. At the time I was not rooted and was running 100% stock.
I'd most definately take that phone back and exchange for another.
It _might_ have been a one time issue, or it might have been a symptom of a hardware issue. Why risk it?
Thats not really a common issue... in fact the first that Ive heard of. Could be a one time issue... or a hardware LCD/screen issue. Id take it back.
I hadn't heard of it either. When it happened the phone was only a few days old.
I regularly replace iphone 4 screens and I have come across red tinted screens. At least on them it was a sign of screen problems, not software. Samsung does/did make screens for Apple. I've never heard of an iphone having a red screen then dying. I have heard of them being red and not ever going back to normal colors.
Not worth the risk for me. If it was my phone I'd exchange it.

I had a similar experience, except the screen went green, and wouldn't go away until I rebooted. It was probably due to CF.Lumen though, or at least that's what I thought.
On my Captivate, every once in a long while the screen would boot or unlock with a weird color tint. Seem to recall it having been green, but couldn't swear to it.
Either way, a quick lock/unlock again made it go away. Always figured it was a software bug somewhere in the display driver...

[Q] Gradient across screen

Hey guys,
So, today I got my phone back from Samsung (yay!) after repairs.
First issue, it came back with a different bezel, so I phoned up thinking "OMG WTF" and was told "Nah, we just did that because we had no others".
That's fine, boot my phone up, and then the menu lights didn't work.
Me: "WTF!!"
Reset the phone, display lights worked. Yay :3
Open "Gmail", oh, it looks like there is a gradient going from dark to light over the screen. Whhaaatt.
I turn the brightness up, it is less visible. Full brightness and it's barely noticeable.
I restart my phone, nope, it's still present. I notice it in the Android Market too and can just see it when the phone is idle.
I've tweeted Samsung, but I'm impatient when it comes to my phone, it's been difficult going with my trusty P1i for a week!
Thanks for all your help guys,
Jake,
P.S.
Going to try formatting again...
Well, another reset didn't do anything.
Sending it to Vodafone's repair centre now, to see what they can do...
I'll keep this thread updated!

Flashing White Screen

I was woken last night by a flashing light in my room, the screen on my N10 was cycling between white, black, and backlight off.
The power button would not wake the device, the only thing I could do is hold the power button down until it turned off.
On powering back up, everything was fine and it didn't do it again.
I don't have any apps installed that would cause this, no screen flash notifiers or anything like that, what the hell happened?
I had that happen once, about three weeks ago. Also don't know why, but it hasn't happened again since.

Maybe OP has an Ouija Board app installed on his N10!?!?
Happened to me too
The screen was flashing a monochrome pattern that looked like a TV test pattern. I had to reboot by holding down the power button. It hasn't happened yet. It also went completely black another time and wouldn't respond, I had to reset it that time as well. I was afraid that it was because I bought a reburbished Nexus 10. I'll repost if it happens again.

You bought a refurbished N10? Interesting. I'm curious - how well does it perform? Any issues, other than the aforementioned? I can only afford a refurbished model at the moment, I'm looking at the one currently on eBay buy-it-now 32GB for $430; are the speakers okay? How is the battery life? Solid?
Sorry for derailing the topic, you're just one of the first that I've seen who have bought a refurbished model.
That's probably the memory leak in the graphics driver that some people mentioned (and the crash resulting from it). I had this happening 2 or 3 times on my N10, but only after long uptimes (2-3 weeks). Until it gets hopefully fixed .. reboot more often.
It works well. The speakers sound great, the battery life is pretty good (I use it a lot). It does charge a bit slow, but I may buy the pogo charger.

Flashing/flickering/artifacting screen?

(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new

Black Shark 3 pro screen turning green, heat issue.

Phone is global version, worked great for a year, then started getting green edges on screen when phone warms up, then ghost images of icons, text etc eventually screen is unreadable and a grainy green. I don't know what to do to fix it, or where I can have it fixed. Here are photos. It heats up and does this just searching internet or watching youtube. If i try playing game it does this within minutes. When cold is perfect screen.
I am in USA, which makes it harder to find place to repair. Started using a Redmagic 6 since the BS3pro issue.
Another thing interesting, my phone did not upgrade ota since I first bought it. After i moved everything over to the redmagic 6, I reset the Black Shark 3 pro to factory settings. Once I restarted the phone, I seen new update, ended up installing around 4 updates and phone has more features, settings look different etc, wish I knew this in past. But green screen still there, so a little late grrrr.
