Screen not working on wake up? - Nexus 5 Q&A, Help & Troubleshooting

So I've been having this weird problem for the past few weeks, where on some occasions I would wake my phone, but instead of getting any image, I just get a entirely black screen with the backlight on. At first I thought it was from CM12.1, so I tried another ROM (Euphoria OS) but got the same problem. Flashed back to stock from Google which seemed to have fixed things, until today where it happened yet again. Does anybody happen to know what is causing this problem? I want to see if there's something I could look at before I get it try and get it sent off for repairs (I flashed back to stock and locked the bootloader again).
Thanks.

[Q] Nexus S not waking up from sleep

Hi, I have a i9020T and just gotten it about 10 days ago.
Long story short the phone was dropped and the screen quickly started changing colors until it completely failed. So I order a new screen replace it, now everything looks good, the phone starts up normally, at this point everything is stock, factory reseted and everything.
Good right, well as soon as I put the phone to sleep it fails to wake up. It seems to function perfectly, buttons work I can unlock, I just can't see anything. Now matter how many times I restart and sleep the phone just doesn't wake up.
So I decide maybe another ROM/KERNEL could fix the problem, I was wrong. I have tried about 2 kernels, and 5 different roms, still nothing.
I am going to try and disassemble to see if there is a possible error, but other than the fact the phone wake up, it seems to work perfectly, CWM everything.
I cannot figure out if this is a hardware issue, but I am sure its not screen related. Hopefully not a motherboard issue.
I have searched google, xda everywhere yet no solution only few cases, but no real solution.
Thanks.

I'm having the same issue. Then sometimes it randomly starts working again, but soon goes back to not waking up.

Touchscreen stops working after waking up

Found some threads mentioning digitizers causing issues with this on other models of hardware, but doesn't sound the same.
Been holding off on rooting my Note that I've had for a week to wait for stock recovery, kernel, etc. to be out in case I had issues.
Rooted no issues, went back to stock just to make sure I could, then rerooted.
Not sure if coincidence, but now if I let the screen time out or manually do it, then wake it up.. my touch screen stops working. I can hard reset and it works until I do the same thing, then stops working again.
Anyone else seen this?

[Q]half screen flickering with grey,and keeps getting worse

since a few days,on my screen kept coming a light ,gray flickering on the down half of the screen that lasted just a few seconds,and then disappeared.
then,yesterday even the upper side of the screen got affected.
Since I noticed some improvements through unlocking and locking the screen,I thought it was a software problem (I have trickdroid 6.0 installed,so I reflashed the rom)
after full wipe and rom reflashing,the problem was still there,it keeps coming out after a couple of hours,but it was still present.
today I did a factory reset from the bootloader(deleting everything)and reflashed the rom.still there.
anyone got the solution???would help a lot,thanks!!!!:fingers-crossed::fingers-crossed::fingers-crossed:

Well, the only thing that comes into my mind is to full wipe, download a different rom, flash it's own kernel and try it...
If it's still there, I am afraid it's a hardware problem.
since the problem keept being there,I sent it to htc...the motherboard was faulty so they replaced it

[Q] [HELP] Phone suddenly freeze and show weird screen

Hi, I have been looking all over the internet and search the xda thread but I couldn't find anything related to my problem.
So this morning when I wake up, I turned on my phone and after I used it for awhile suddenly my phone stopped working (freeze/hang) and started to reboot itself. After it reboots my phone's screen as per attached below.
The problem lasted for a day and started to driving me nuts!
Anyone experienced same problem?
I am running KK4.4.2 fyki.
Thank you very much for your kind help!
are you unlocked, rooted, custom recovery, rom, kernel, anything? can you access the bootloader?

Nope, I am all stock without any modification nor and fancy stuffs.
Just pure android 4.4.2
I am thinking that the hardware might be faulty..

If you're stock, it could be hardware. Though have you ever attempted to root?
Is it just randomly happening?
Definitely hardware

Yes, it just randomly happening. It started yesterday morning until now..
The phone started to not responding at all and then my screen goes broken (same screen as broken TV I might say).
If I let it cool for 15-20 minutes the phone is usable, but then after 1 hour of normal usage the phone started to freeze again.
Just curious, none of you experienced the same?
this kinda looks like the static i was getting on screen on my n7 2012 when i let the battery get too low. charging it up and a few reboots fixed it. but im not sure if that's what is going on with yours

I just got mine, 32gb from the playstore, a few days ago, and nothing like that.
If it's happening when your device is hot | overheating, you may wana see if you get it replaced.
It happened to me once. The phone was with his screen off and when I try to turn it on that exact same screen came. But it just happened once, also I experienced random poweroffs and reboots. I did a factory reset and power off issues and freeze stops, but had one reboot once I start installing my apps. I think its a software issue but I'm not sure.

I'm glad (and kinda of sad) to know that I'm not the only one with this issue.
The problem started about two weeks after I bought mine(Telus). It's done this about 5 or 6 times,randomly.
I found that having someone call me will "unfreeze" the device and the screen gets back to normal.
The first couple times it happened, I was running stock 4.4.2. I since rooted it and installed Xpposed/GravityBox and I'm still getting the problem...
I think that I'll have to return it...
Idk if i need RMA the phone. Its a great phone and the reboot issues has stopped. What should i do?

Hi, I have the exact same problem, I posted a video on youtube /watch?v=m0EkC_ak01g but I got to the same conclusion that it might be a GPU issue. So there is nothing I can do right?, the worst thing is Im in Argentina and LG dont take my warranty because I bought it in Germany. So there is absolutely nothing I can do?, I know how to avoid the flickering a little bit, when I hit "Ok Google" button it seems responsive and as long as I touch the screen it works (you can see it in the video) but as soon as I stop touching it, after 2-3 seconds it becomes unresponsive again, and when I say unresponsive Im saying the screen doesnt reflect what Im doing, I can still push the buttons and all. So Im not 100% sure its a GPU issue, but a software too. Thanks.

Black screen OnePlus 6

Hi,
I got my new Onelus 6 five days ago, and i installed the latest updates (ONEPLUS A6003_22_180614).
For the last three days, i've had issues with the screen going black. When i lock it and then try to unlock it, the screen doesn't switch back on, it keeps being dark.
I tried to reboot it several times (Volume button + power) but the screen is still black. The phones vibrates and the LED works but the screen doesn't.
I tried to remove the SIM card, but the problem is still here.
Sometimes after 100 trials, the reboot works, but the problem comes back as soon as i try to unlock it.
Do you know where this bug might come from ? Firmware problem or phone problem ?
I really don't know what to do... I hope you'll be able to help me !
Thank you
Sounds like you should contact OnePlus and it may be a defective phone. Maybe have to RMA it and have it replaced.

Have you tried a factory reset,or using the msmdownloadtool
My phone is brand new, I don't think a factory reset would change anything, does it ?
I want to see what OnePlus support can do for me before trying anything with softwares on my phone ! (I don't want to loose warranty)

I had a similar issue within a day of getting the phone. Nothing worked and had to send for replacement.
Try to reset to the factory settings. If this can't help you, refer to the service center or to shop where you bought the phone.
Hello. I'm having the same problem. Bought my phone couple days ago and it runs ONEPLUS A6003_22_180713. Don't know what to do sinse there is no OnePlus service centre in my city. Have your problem been solved? Have you done anything special?
Hi,
Unfortunately I had to send it back to the website where i bought it. I have been refunded, and i bought a galaxy S9+ (cheaper than the OnePlus 6 i got)
Even i got the same issue since Pie update.
Had rooted when it was on Oreo, when Pie (OOS 9.0) update came, it came with a new issue. Whenever I unlocked the phone, the screen would flash with blue lines and black background multiple times then show the lockscreen. And now with OOS 9.0.2 the issue went even more drastic, the screen kept on flashing while using apps. Even forced reboot didn't solve the problem. I had to power it off and leave it aside in nighttime. The issue has decreased but the lockscreen flashing still exists.
Temporary fix - https://thedroidguy.com/2018/07/how-to-fix-oneplus-6-that-wont-turn-on-easy-fix-1087099
If the issue increases, then I would restore Oreo ROM and relock the bootloader.
I need help tooo!

Best solution is to keep the screen ON always. Or else that flashing bug will keep recurring.
But this is a temporary fix and not all would like to keep it Always ON
Same here from 3 days ago. OX 9.0.2
The phone hangs, No respond and must hard-restart the thing.
Same issue here,since the past 2 weeks.The phone screen keeps flashing when the phone is locked and even restarting the thing 20 times doesn't make the phone start.The LEDs work fine,the phone receives calls and messages too but the entire screen is black and unresponsive at the moment I face this issue.The moment I lock the phone the issue crops up and it's a pain to restart it every time it happens.
