[Q] HELP: screen unresponsive when woken up ONLY - Nexus 5 Q&A, Help & Troubleshooting

This issue make absolutely no sense to me, and only started yesterday.
First, I am stock, unrooted, no mods, no crazy sideloaded apps, just a good old Nexus 5.
When I go to wake the phone, I have noticed that the lock screen is 100% unresponsive. I cannot enter a pattern lock. I then switched to a PIN lock, thinking maybe there was an issue with the pattern. Again, unresponsive screen. So I took my screen lock off completely, thinking there is maybe an issue with the lock screen in general. Again, even with no lock screen, I cannot swipe screens, open apps, nothing. This also includes the soft keys at the bottom.
I decide to factory reset my phone. I update only my Google apps, and again notice the same issue. The screen is totally unresponsive, but then 2 white lines will flash at the top, and the screen will work.
Once those white lines flash, the screen is completely responsive like normal, there are no other issues until the phone goes to sleep again. Sometimes the little lines flash 2 seconds after waking up, sometimes 30 seconds, sometimes I have to hard reset the phone.
I also am linking to a YouTube video that I recorded of the issue in case I am not making sense.
So can anyone explain this to me? What could cause this issue on a phone that has never been rooted or flashed or anything?
Thanks in advance for the help!

Weird. Issue. Maybe you should stick everything from your sd to your pc.
And flash a factory image from fresh install from here - https://developers.google.com/android/nexus/images - if you're lucky the drivers maybe corrupt and not the hardware
Sent from my Android 5.0 Nexus 5

Could also be a loose connection. Maybe the flex cable to from your screen wiggled its way out a bit. I've never seen that before on any phone. I'd back everything up and flash a factory image. If the issue persists, contact Google and see if you can RMA the device.

Need help identifing reason for strange and frequent freezes

Hi guys
I have this strange behavior going on in my Sentation.
Out of nowhere my phone started to have strange screen behavior... Didn't light up after pressing the power button (had to phone my self in order to get screen on).
The next thing was that suddenly the screen goes to maximum brightness or goes to minimum without any explanation (tried both auto brightness or manual).
After that I noticed that the screen went off when I was using it but when I pressed the left side of it it lighted up and off again... making me think of some kind of bad contact underneath. As I already had changed a broken touch screen for t3 times, and let the phone fall for several times I thought it had to do with some plug out of line...
I disassembled the phone completely and mounted up back again. The thing is that the phone started to freeze every 5 minutes (screen on but completely freezed. I have to pul out battery). Sometimes it freezes even in the recovery menu. I've tried several rom's with full wipe and not installing anything and its all the same.
Some times I still not that the screen goes off during the freeze but when I touch the left side it goes on again, but that doesn't change the freezed state even that I let down the phone for several minutes.
I disassemble the phone again, tried different back cover and different battery (one stock and other extra strength) I tried also all the suggestion related to the small pin in the back not connecting well with the back cover (adding an aluminium foil, pulling the pin out, etc..)
Nothing seams to resolve anything so I have clearly an hardware problem... but I don't know what to replace or where to look the damage!!!
Can anybody help me please?!
Update
I have an update on my problem:
I noticed that when I leave the phone on top of some kind of metal part and don't touch it it works all day without any problem but, as soon as I start to touch the phone, it freezes within minutes!
Could it be some kind of static electrical problem? How to resolve it?
I would apreciate any help
Thanks

Random screen crashes, freezes, glitches

Hello! I have a stock Android Lollipop 5.0.1 Nexus 5 and for the past week or so I have been experiencing a weird issue.
The device randomly crashes. By "crashes" I mean the screen goes black, but the backlight is still on (it's a lighted black). I can push the power button and it will turn completely black (locked) and if I push it once more it turns lighted black again.
To get the device back into usable state I have to keep the power button pressed until the phone resets. Sometimes I keep it pushed for a full minute and nothing happens, sometimes 10 seconds are enough. Sometimes it will go through the "Google" logo and then stay in the lighted black state until I finally manage to reboot it again. Sometimes it crashes again right after it boots up.
It's weird because a lot of the times it's ok throughout the day and then when I go out in the evening, I take it out of the pocket and I see it crashed. Sometimes it crashes while I actually use it.
Last night it started doing something else: instead of lighted black, the screen is filled with static noise. It doesn't move or anything, it's a still image. Today, when a crash like that occurred, the screen glitched first (random lines on the screen, some parts got moved, really weird). I will get some photos if it happens again.
The problem is that I can't identify what's causing it. There is no particular app or action that I do / use that triggers this. It also doesn't seem to be movement-based, as it sometimes happens while it's sitting still on a table.
I updated to 5.0.1 about a day before this started happening, but I'm still not sure if it's software or hardware-based.
I tried a factory reset and booting into safe mode, none of these helped. I will only consider flashing a custom ROM as a final resort, because I'm not sure if it voids the warranty.
PS: the device is still under warranty, but I'm away for the holidays and will be until the beginning of the next year. And I'd like to have a usable device, especially while I'll be on the road.

I have none of your issues, try booting the device in safe mode and see if the problems still occure. It must be a or multiple downloaded apps that are causing your issues. Or try a data factory reset and restore/download your apps one by one amd try to identify the culpritt.

I said in the post that I tried both of those things. The crash occurred seconds after booting in safe mode and factory reset did not help either.

Flashing the 5.0.1 factory image in fastboot should fix your issues. Or try flashing system.img first, maybe thats enough.
Same issues with my Nexus 5

I am experiencing SAME exactly issues in my N5 with 5.01 and 5.1 . EXACTLY... you are not alone
Seems a software problem (third party app ?) , started in 5.01 and now is in 5.1 , of course system and boot images where flashed with fastboot, so no solution using
Stock, Rooted, using Nova Launcher - Smartwatch 2 - Google Cardboard - Chromecast and many apps.
But started ..if memory helps .. after installing Cardboard 3D apps.

My phone had an issue with the screen. I went to the LG service and they replaced the screen entirely, so that's that.

Screen is constantly locking for no reason, is my light sensor busted?

Hi all,
When I'm using my month old Nexus 5 it will just randomly kick me back to the lock screen, sometimes I can just unlock it and keep on trucking but sometimes it will just immediately lock again or it will work for a couple of seconds and then re-lock. Once its in this state even a reboot doesn't always help and about the only thing I can do is get into recovery mode and re-flash it again. I used the Sensor Box app and have noticed that the light sensor is always reading zero, and I'm not sure if this is part of the issue?
This was happening on the PA Alpha, Stock 5.0.1 and since I was still having the issue I flashed back to 4.4.
The weird thing is that my phone had been fine for the 3 weeks or so I had it before hand. I flashed lollipop on it less than an hour after I took it out of the box and it had been running smoothly up until yesterday.
So a few questions:
Is there anything I can try to fix ir?
Can I use debugging to see what is causing the screen to lock?
Is this likely to be a hardware issue?
If it is, is there anything I will need to do to make sure I keep my warranty?
Any help is very much appreciated.
Bump with some other information:
I don't think its the light sensor, I tried using the phone in a pitch black room last night and the same thing was constantly happening, there was something else odd happening though.
From the restore of 4.4 I was on the "Select language" screen, whilst I could swipe and roll the various language options up and down the moment I presses "Next" the phone locked, if I left the phone on this screen eventually the screen would automatically lock and then it would keep locking itself constantly again.
Also, just for total clarification by "lock" I meaning "return to lock screen" not freeze up and become unresponsive.

Galaxy J700T Black Screen Non Responsive, Flickering, Boots Normally

I've come up with a problem that has perplexed me on my Galaxy J700T. I've looked everywhere for solutions, but none have worked.
The phone's screen will go dark after it boots, but will show the lock screen for a split second. The screen will sometimes flicker back to life for a moment, but then go back out. This can happen a few times. Sometimes it will go back to the same screen, but sometimes it will show the lock screen. Sometimes it will show the lock screen on a flicker, but then go back to whatever normal screen or app it was on before, when I hadn't unlocked it. This only happens when it was on that screen previously though It sort of Flashes the lock screen I suppose you could say. The phone's screen seems to be unresponsive when it's black.
I'll start with what I know:
It isn't solely a hardware issue - The screen does turn on when you first turn on the phone. It shows the boot process. You can boot it into Download mode and the screen will stay on. You can also boot it into Recovery mode and there will be no problems with the screen. The phone can boot normally and the phone will show the whole process. The problem is post boot so I find it hard to believe it's solely a hardware issue, otherwise I should have these problems in the other modes too.
The screen isn't always off - I've managed to actually catch my phone displaying messages at the bottom of the screen for a split second. One such being that it has connected to the internet. This will show for a split second, while the rest of the screen is still dark. The screen appears to otherwise be dark with no light, looking as if it is off.
I've looked into this black screen of death issue I've heard about. I'm not sure if this is it. I've never had the issue before with any other android device I've had. It doesn't seem like it when I look at descriptions of the problem.
I have put the phone through Factory Reset, which hasn't worked in stopping the problem. As soon as the welcome screen shows up to set up my phone, it will go black again. I cleared the cache. I Cleared all data and reset it. Rebooted it in different ways. I did root it.
Would anyone here happen to know what's going on or have any possible solutions?

[SOLVED] Half of the screen flickers black between unlock and home screen

Couldn't find any similar topic except in forums for s10+, OnePlus and other phones. Sorry if I missed anything.
As in the subject, after unlocking, approximately half of the screen flickers black and goes to the home screen. It takes less than a second. Always top half, bottom half shows home screen right after unlock. This does not happen on each unlock, but also, there is no pattern - it can be after 5 or 30 unlocks, it can be after 5 minutes or 10 hours of not using the phone. It started mid-July and not only annoys but is starting to worry me. Solutions from other threads didn't help. For example:
Fingerprint sensor problem - I don't use it, I have pin lock.
Samsung Pay issue - I don't even have it available, so, don't use it either .
Animations - setting them off did not help.
I cannot guess anymore what would be the cause, if it's some app which wakes up after unlock or what else. The only thing I've changed (except updating apps) was adding another sim card, but my tiny little brain cannot find connection. I didn't test removing it as I need this sim active and don't have backup phone right now. Also, I would really like to avoid resetting the phone...
Did you experienced anything similar?
Thanks a lot for any help or suggestion.
are using Samsung or some third party launcher. Did you wipe cache? Latest firmware updates?
Yes, I did both, firmware update and cache wiping, no change. I'm using stock launcher.
did you try in safe mode to exclude some app causing it
Yes, I tried safe mode without success.
i would take it to Samsung repair centre if pos
Thanks for trying and all the steps. There's nothing like that where I live, neither any advisory place except for hotline. I can drop it at their service but will need to wipe it down before, which I keep as the last resort. I'll keep waiting for another firmware update and if nothing changes then I'm willing to do the hard reset. I just hope it's not a symptom of some virus - I'm trying to be most careful, scanning device periodically, didn't root, so I naively count on being safe...
i don't think it's virus. fingers crossed it's just software issue
hi again, just to let you know, I think I know what was causing this flickering and now I feel silly . Home screen rotation. I had this option turned on, and it's possible that sometimes, when I put my phone on the table, home screen rotates to horizontal position. Of course it locks after few seconds. I've noticed it completely accidentally, because one time, when screen flickered black there was slow-motion rotation animation in the background (which I've never seen before). That's why flickering was completely random to me, not connected to any type of notification whatsoever. Well, it's not, it has a pattern . I've checked it plenty of times and each time I lock my phone with home screen in horizontal view, but unlock in vertical, half of the screen is flickering black. That's it, at least I believe it must be this, because it happens each time and never when I lock my screen in vertical position.
Once again thanks for all the help!
