Black screen & no recovery!!!!

Hi all !!! Sorry for my English but I need your help
I commented what is happening with my phone N5 (which for good and evil is always stock without root or anything, with corresponding OTA updates.)
1- Yesterday afternoon at lunchtime while reading a book in playbooks, I notice that suddenly disappears one line and then appeared intermittently. I close the app and noticed the same thing happening on the screen menu. I shut down the cell and turn on again and I thought it must be an application be kidding. But still does.
2 Also yesterday I happened to change the security on the phone screen. After a while of normal operation, try to turn it on the screen with the button, nothing, the screen goes "black", with light and retrolight turned on but no picture no nothing .
Called the cell to see if it works or is turned off and the phone rings but the screen nothing. Try turning it off and on again by holding the on / off / lock button and the phone restarts, but the screen nothing. In one such attempt to do the above it is seen that managed to turn it off. And I get it on and do a normal boot, except that the picture of my screen is changed to the original. Change the lock screen which was previously using (slip). And it seemed that out or some conflict with the lock. In one of those again pressed the ON / OFF / lock as would normally and it starts all over again.
After I magically back to life, I want to make a full wipe as I think it should be an app that is doing some conflict or something. BUT ....
3I turn off the phone and then press the keys VOLUME UP / DOWN and ON / OFF is normally off, squeezed the first screen with the options but options RECOVERY / BOOTLOADER appears in red I choose RECOVERY give the ok with the key and .... andriod robot appears with the legend below that says something (I do not remember well) without or without controls options appears. So its seems thatI dont have recovery.
After that keep pressing the key ON / OFF and the phone turns off and / or reboot normally. All this I did it again to see if the error reappears and looks that I do not have recovery.
The failure of the screen is increasing. I dont know if they are separate problems or is it all the same problem.
Sorry if I was too long but I need the help of you.
UPDATE Now it seems that the screen died, since I do not achieve to turn it on as before, the light and the retrolight its ok. The phone receives calls and notifications but the screen stills black.
Thanks all.

sometimes things just "derp". itll happen more often if you dont reboot your phone often. also, your phone will be a little bit more responsive if it gets reboot once a day or two.

RMA or fastboot it back to stock, if the screen doesnt turn on afterwards then it looks like a hardware issue, open device and reconnect the display.

[Q]Screen doesn't turn off when locking

Hello everyone.
I have a couple of problem with my xperia Z3. The problem is that when i press the side button to lock the phone, the phone get locked but the screen seems to be still on(and then turn completely off after a few seconds) . I mean that even if the phone is locked it's like i am seeing a completely black image. This doesn't always happens with Android KitKat but with the Lollipop upgrade i made yesterday flashing a generic Baltic firmware, the problem got worse! When it happens the screen stays on even after few seconds and it doesn't turn off and i'm forced to restart the phone to "solve" the problem. If it helps, when the phone locks fine the screen turns off immediatly but when the phone has this problem when i press the lock button i can see for a moment the screen locked, with the clock, the padlock icon, the fast dial icon and the fast camera icon ecc and then the screen turn black(but still on) like "something is slowing/blocking the phone from getting locked"
The second problem that i have is that sometimes when i make a call or recieve one when i put the phone to my ear the screen doesn't turn off and the tousch screen still works making me end the call unintentionally touching the screen with my ear for example. I haven't had this problem yet with Lollipop, but I used to have it with KitKat. Anyway this is the less important problem that i'd like to solve because even if the phone should work proprely by itself i can always accept the call and then lock the screen with the side button "solving" the problem of unintentionally ended calls. But the first problem really bothers me a lot and i'd really like to know how to solve it.
Does anyone have at least one of this two problems and knows how to solve them? Thank you !
I'm sorry for my english and i hope i've explained myself well. I've just restarted the phone so the problem at the moment doesn't persist but the next time it will happend i will make a short video to make you see exactly what happens or if you think that this two problem could be caused by an app just tell me and I will write you a list off the app that i've installed.
**Edit: I'm really sorry, i haven't read that this was the wrong section for questions, could someone move it to the right one? Thanks.

Help - My new SM-G930W8 S7 hangs on wake

Now this doesn't happen all the time every time, but usually around a notification and the screen is off, I go to hit a button to turn on the phone and it doesn't respond but the touch-keys are backlit. If Always-on Display is on, the screen is black regardless, not even showing the time or notifications. The only fix is waiting ~10 seconds for the phone to respond, which in some cases can be the difference between a missed call.
Now, seeing Always On Display off like that while it should be on made me think back to when I saw some sort of Nougat optimization setting that allowed me to select Always On Display, and as far as I remember, I did. That makes me think this process is killing AoD and it is taking that long to start back up, where the phone won't unlock until AoD (is back on and) can confirm that it's trying to wake up out of that state.
However, I don't believe this is the issue. I have turned off AoD and the issue still happened directly afterward, after a Messenger notification. This is stock firmware, however it is not factory firmware. I believe I downloaded it from Sam-Mobile, and they had the 7.0 Nougat upgrade that I would have gotten OTA with the factory firmware anyway.
Somehow I don't think it's the flashed firmware that is the problem, however please let me know if that's a possibility.
While the phone (or whatever) is hanging, I can still hold down the power button and I will feel haptic feedback as if the power menu has opened, and when the phone responds the power menu will be open, so the phone does still receive input. It just doesn't seem to act upon it or wake the screen properly. Is this perhaps merely a known Nougat bug or is it a glitch with my flashed stock firmware?
I'm sorry I don't have much more information. I do have Greenify, but I don't think that can or is set to disrupt anything that would affect the phone waking, or that would hang the OS, homescreen or whatever it is.
I haven't done other troubleshooting because I don't know what direction to attack this from, and that is why I have come here.
Help please!
Thanks in advance. :good:

UPDATE: It seems to happen directly after my screen shuts off from being on. So, if a notification wakes my phone but I don't interact with it in time and the screen goes off, when I press the power button it won't respond for ~10-15s. That's all I've really noticed... Anyone else have this problem??

BUMP.
Also, the same thing happens if I press the power button on my phone (by accident) and then go to turn it back on almost immediately - it won't respond for a while.

Cleared cache from recovery?
Got any settings enabled like "Keep screen off" which stops the screen coming on in your pocket, try disabling it in case that's causing it
Different gestures, disable them all in case they're messing with it
Last resort, factory reset

Won't be factory resetting unless I plan to root or something. I'll fiddle with the keep screen off setting that I do have on, and I highly doubt gestures would affect it but regardless I haven't enabled or used any. Thanks for the reply.

So the "Keep screen off" setting didn't affect anything. I turned Always On Display back on and I see the same issues. However, now sometimes I notice when I lock my screen or it shuts off, sometimes the AOD will appear and then quickly disappear, and stay in this hanging state for 10-15s. Then, if I haven't touched it during that time, the AOD will reappear. Any ideas? :/

So nobody else has this issue? This is still a problem, even if I press the power button and sometimes I'll want to turn it back on again as I just remember something to do before putting the phone away, it hangs on black for too long to be useful in that moment. The only potential solution is a factory reset?

Even if I lock the screen... If I try to turn it back on too soon, and I think it's specific timing... I have to wait 10-20 seconds. Sounds and vibrations still work.

UPDATE: This is still an issue. I've noticed a few more things, it does really seem like timing and as if there's some function in my phone literally not allowing me to turn on my screen - and I have never timed it but I think pressing buttons (power button) makes it take longer before it will respond again.

This happens for me also as a point of interest.
I am hoping that O solves it, since the monthly updates have never helped.

I haven't had this happen since upgrading to Oreo a week ago, so far so good!

"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.

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.
