[Q] HELP: screen unresponsive when woken up ONLY

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.

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.

again and again...
i'm in the same case... I don't have any clues or solutions, i'm just wainting like a dumb... I don't know what to do, i always have to make the thing with the power button and the lower sound button to make it show the boot screen, but it glitch after few seconds... PLS HALP

"Force touch" home button stopped working?

An hour or so ago everything worked fine, and then I updated my playstores pending apps (only Fleksy was pending) and the "force touch" feature of the phones seems to have completely stopped working, no matter what setting I turned on or off it didn't work...
Anyone has a clue as to what can cause this?
General notes:
1. Using stock Exynos unlocked variant
2. I am using package disabler (which btw didn't improve much my battery life, but that might be just me using the phone too much ) so maybe one of the packages decided that it depends on a disabled one?

I noticed mine stops working after a reboot and takes about a minute or two to get back up and running. Try a restart after clearing caches, if nothing still, reboot in safe mode. If it works, then its an app you installed interfering.

Mine also stop working after I restart my S8 Plus, it will again work if I wait around 20 minutes. Is this software or hardware problem? Any solutions?

Wish mine would stop working permanently! can't stand that feature forever brushing across it and waking the phone up!

How does it act up on your part? Mine would just stop working if I restart the phone & I should wait sometimes hours before it would work again.

Every time i'm installing my phone in my car mount I need to hold the phone from the bottom to install it correctly and brushing my fingers across the bottom is constantly waking the phone up, I've lowered the sensitivity to it's minimum.

I see, problem is not the same. On my part the tactile home button simply doesn't work when you press on it. I have to double tap to wake the phone when on lockscreen.

Unless your phone is unlocked no pins etc the phone will just go to the lockscreen, it's a useless feature, most people have the phones locked and thus it's a complete waste of time, it sounds to me the capacitive home button part of the screen was an afterthought because they couldn't install the fingerprint reader under the screen, just had a software update yesterday and still can't turn it off, basic stuff Samsung should enable an ON/OFF toggle switch for this.

Had the same problem with my S8 Plus India Variant(SM-G955 FD), I got my screen replaced from service center, Device was not rooted back then, so was under warranty.
But it is an hardware issue, as since then it has never gone off.

I mean when I press the home button hard it doesn't wake the phone up & no vibration. It happens when I restart the device then it would stop working for few minutes to a few hours sometimes, then it would start working again normally until I restart the phone again. I think this is just a software issue.

[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!

Question how to fix random black screen after opening phone

My z-flip3 5g has a strange problem. If i close it (by folding the screen closed), then after opening (unfolding) the screen and touching the right side button/fingerprint reader to unlock it, i hear the quiet "click" noise that indicates the phone is unlocked, but the screen stays black. i then have to repeatedly push the lock button on the right to lock the phone again and unlock it again. after several attempts the screen finally turns on. sometimes it will go black a few seconds later and the same issue continues. but other times the screen will stay on and work fine.
i have noticed that if i do not close the phone (folding the screen together) then i do NOT encounter this issue. the phone screen turns on when pushing the right side button (or touching the fingerprint sensor) and everything works fine.
this issue started yesterday, a system update installed yesterday as well, could it be related?
i already restarted many times, booted into recovery mode and wiped the cache. nothing has helped. the only way to avoid the problem is by not closing (folding the screen shut) the phone.
One UI v 5.1
Android 13
Security patch level Feb 1, 2023
fully stock/not rooted

I have same behavior. Did you solve this problem?

Unfortunately no. Did a factory reset, hoping that would help, but the issue persists

Mine has recently started doing the same. Last update was right before this started several weeks ago. I don't have mine set to require fingerprint, it should just turn on after opening. If I open it partway, it will turn on, then turn back off when fully opened.

hi,
i have same problem, it's software problem?

Not completely sure about that. They update this thing so often, it could be coincedence that it started shortly after an update. I want to try blowing out the hinges as I've got some dust under there that I hear when opening the phone. Definitely not a phone to put in your pocket after working in the wood shop!

and don´t take it to the beach either!
What is also strange is that when I close the phone and open it a few seconds later, there is no issues whatsoever. However, if I leave it closed a few minutes, then when opening it, the problems with the screen staying off happen.

Yes, definitely don't take it to the beach!
@netridah , mine is doing exactly that. Which makes me wonder is it a wake issue, or a mechanical/sensor issue with the hinge.

one more to the bill
I checked the flexes and I warmed up the logic nothing works

I have the same issue: Flip 3 - 5G with OneUI 5.1 - 1 April Patch level
When I open the phone I eventually see for less than one second the lock screen, the goes black and unresponsive.
Then I have to press the button to turn the screen off (even if it is already) and then re-press the button or use the fingerprint to turn it on and it will work (eventually, sometime I have to do it a couple of times).
I already googled it on many forums but no solutions, I've tried to:
Disable the always-on display - no result, at first looked like it did the trick but the day after was having the same issue.
Check all the updates of the system components like always on-on display (settings --> lock screen --> always on display --> info), no help everything is up to date.

Hi,
I have the exact same problem, only difference is that I'm on the z flip 4.
I get the black screen and sometimes when opening or closing the phone the screen can flash in a bright yellow or green color.

I got a motherboard but the problem continued
Next step changing screen is very expensive at the moment

This is driving me crazy - also started the day I updated to OneUI 5.1.
Hoping for a solution soon!

I am also encountering this problem, I went to samsung repair shop 1 month out of warranty, sales person said it is a screen issue and needs to be replaced for 430$. Mine was before the update, i took mine near the pool, got wet maybe, as the alarm for usb charging mentioned unplug it immediately, day after it began randomly dark when phone is openned fully. Zflip 3

Oh just an update, i did some tinkering today, Good lock all updated, disabled clockface, sprayed some contact cleaner on power button, and hinges, fold close and open for a minute or two, fell asleep for 1 hour, and when I woke up, my screen works back to normal, it wakes up when unfolded, no more waiting or hitting the power button several times. hope this stays like this.

Hi, few days now, I still have occasional blacking out, I've tried putting my phone on safe mode, and this seems to solve the problem. I suspect it may not be hardware fault, but 3rd party software, "good lock" or something else that conflicts wit one ui, that makes the flipping open lag waking up. Contact cleaner used for electrical stuff

Didnt use my z3 for about a week let the battery drain.. then charged it too 100% without turning on the phone.. my phone back to normal now.. hope it works for you guys

Hello,
I am using Z Flip 4 and last night I started having this problem as well. I can confirm 100% that my phone has no hardware nor a history of impact of any sort that's why it's really frustrating having this kind of problem.
Has anyone already found a resolution for this problem?

Z flip 4 here also. Had the same problem with the screen. Took the phone to Samsung and they changed the screen, frame and back panel's for free under warranty.
They said it's a hardware issue.
So better to take the phone to Samsung.
