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.

I just started having this "bug" yesterday. Basically, what happens (randomly) is that when I press the power button, remove the stylus, or slide the phone open to wake it up I'll be met with a black/blank screen. The backlighting will be on, and the phone is responsive (can receive messages, make calls, sounds/notifications work), but I won't be able to use the screen. If I use the power button to turn the screen back off and wait a few seconds, the screen might start working again. This is completely random and I cannot duplicate it with any guaranteed process, but it seems to be when the phone is waking up from standby. After a soft reset, probably half of the time I'll be met with this same delima, which leads me to believe it's hardware and not completely software.
At the same time the phone is also struggling to re-paint the screen from the change of Landscape-to-Portrait and visa versa. Also opening and closing windows to get back to the today screen also cause a problem. I've disabled TF3D to see if that makes a difference, it doesn't. I have a blank today screen with no plugins to free up the system resources, and am still having this issue.
I'm using JD's Rom (probably around 1.3, it's been running fine with no issues up to this point).
I'm also using S2U2 1.35 (if that makes any difference, haven't had any problems until recently)
The phone has never been dropped, it's in InvisibleShield, and normally sits on my desk charging all day.
This started happening last night for no apparent reason and it's really starting to irratate me.
Any advice is appreciated. Thanks.
Re the black screen:
Sounds like its software related. For example, I sometimes have this if I leave PocketTwit in the foreground and turn off phone. What software did you install yesterday? Also, do you try to press the home key and see if that clears the screen?
After more testing..
After some more fiddling around with the phone I'm about 90% certain it's a hardware issue. I noticed that when I slide the keyboard out if the slide portion is past the number line then the screen will stay on, but not update. I don't know how well I can explain it. If I'm typing and hold the screen to keep it from opening all the way then I can see the letters/words appear (in txt msg/email), but if I let the screen goes and it slides all the way open then the screen will stay on and only show what has already happened, any more typed characters will not appear, but if I move the screen back to the number row then the screen will re-draw and update what has happened.
Is this something that Sprint should fix no questions asked?

The last piece of software I installed was Gyrator 2 on Friday-ish. Thinking that it was the problem, I removed it using MemMaid. I'm going to give the phone a flash tonight and see if it is software related (hoping for the easy fix) but as the post above says, I'm almost certain it's a hardware issue. I just wish I knew how it happened. . . So much for that time putting those InvShld on.
Final Update (this can be closed)
I took it into a Sprint store and they replaced the "flip" on the top for free (I have insurance).
Point of the story/thread, this can be closed, it was a hardware issue, and now it's fixed.
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
Hey guys,
Had my transformer for 2weeks now and loving it. However recently (first noticed it 2 days ago) the notification bar has randomly started opening itself. It doesnt happen on a regular schedule -sometimes it will happen 3 or4 times in a couple of minutes, sometimes only once or twice an hour but not less often than that.
It happens even when im not touching the tablet at the time so i dont think the screen accuracy/calibration would be causing it.
I have turned it off and off a number of times to no avail and Ive also tried a factory reset and even with no additional apps installed it still happens.
Finally ive tried it both with and without sd card in and it happens in both situations.
Oh, and the dock connector being attached or unattached doesnt stop it either.
Has anyone heard of this happening before and or have any ideas to solve this problem?
i get this too all the time. i'm not touching the screen and the notification pops up for no reason. sometimes apps open up randomly too, for example i get an email notification and the email app opens. very annoying when plugged into a projector whilst giving a presentation.
somebody must be able to help. I'm not rooted by the way and have no intention too.
Sounds like a hardware problem - the touchscreen registering fake touch events. Check for mechanical stress in the lower right corner.
Update
I probably should have added, like yours mine isn't rooted.
I also turned on the developer options for touch detection, and it's definitely detecting "phantom" touches in the bottom right corner so definitely hardware not software issue.
Unfortunately, yesterday I started having issues with the touch screen being unresponsive in the right third or so of the screen, so I've called Asus this morning and am RMAing the tablet anyway.
I'd suggest you do the same rob if it's still in warranty, in case its a prelude to larger issues like mine was.
interesting thanks both. i was weighing up an rma because my keyboard dock is getting very loose, letting the top of tablet move about an inch without hinge moving. i've turned on show screen taps and already seen one. thanks again.
The first day allready 2 times black screen out of no where and afther that no reaction on any buttons.
The first time i waited 10 min or more then the S7 reacted normal again.
The second time i pushed the buttons....
The only reaction is when i press the same time: powerbutton, homebutton & volume button down.
Has anyone the same problem?
I had that issue once with the home button. I had to schedule a reboot through the craptastical built in scheduler that is says it is supposed to optimize the device. Search for restart in the settings.
I have the same sort of problems. All in all the s7e seems very buggy to me. Random crashes (especially in oculus app), sd card is sometimes not recognised and after most reboots I get two error messages (one about touchwiz and one about system proc). I'm not sure what is going on.
My wife's is a black too. I had a similar issues with my s6 last year it was the brightness had been swiped to low in my pocket, I was able to barely see the screen in a dark room and turn it up. No such luck with her s7. Hope someone can offer an idea, I'm headed to Verizon later if I can't fix it myself.
S7 black screen
Verizon did a reset for my wife's S7 to fix it hold down volume down, right side button, and the button on the face of the phone together for 15 seconds. The phone came right back on with all apps and stuff intact. Hope this helps, they said this wasn't the first S7 to come back like this they think it's a software glitch.
Im having the same problem....
any one having dead galaxy s7 edge not broken

Try turning off the App Power saving mode!! This fixed the black screen problem on my phone.
I've got the same issue (sometimes 4 times in an hour, sometimes it doesn't happen for 2 days..!!).
I've tried fixing by doing a factory reset and turning app power saving mode off.
Unfortunately this did not fix the problem. Yesterday I got an unresponsive blackscreen again :crying:
Any ideas how to fix this problem?
This happened two days ago with my wife's S7 Edge. She was using it to text me about dinner plans after work, her screen shut off, and it wouldn't work for several hours. The thing was getting very hot. When she was home and charging the phone the screen started working again for a little while, but with several green stripes down the right edge snd aa flashing horizontal band of grey near the top overlaying the screen image. Then when I tried plugging it into my computer to use Samsung's Smart Switch to roll back from the update she had accepted while at work the screen died again. It has not come on since, not even the stripes, and blue or red LED lights once in a wwhile at random. I managed to use Smart Switch to wipe the phone's memory. Then the program took several hours to download something very slowly and install that - a whole new OS update? That completed, and now the charging LED works correctly and the green stripes and grey band are back, flashing rapidly when powering on. Otherwise no screen function. She is shopping for a new non-Samsung phone now. Ridiculous.
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!
