Hello.
Have strange issue with z5c screen. It happens randomly when unblocking device with fingertip.

Reboot is the one thing that helps.
Sometimes can reboot it only with POWER+SOUND_UP.
Does anybody experience the same problem?

Never seen it. Looks like hardwarefault to me. Would send it in on warranty.
I agree.
There's one color issue happening when you unlock the screen with "Auto Brightness" activated (that will be fixed, someday, when Marshmallow arrives). But nothing compared to your issue.

I've had my XZU for a week now, everything has been working fine so far. Nonetheless I've noticed lately that when I turn it on I will see like a curtain or shade of colors from the top down up to half of the screen (it's like a flash, quickly disappearing), apart from that it will resume from sleep fine and no other issues, nonetheless is weird that this is happening now after a week of usage, I hope is not a symptom that something worse is about to happen. I have attached a Youtube link to a short video I just recorded.
NOTE: I do not think is a software problem because I booted the phone is "safe mode" and the exact same thing happened. It seems like a hardware issue that gets worse over time, because at the beginning happened once out of 4 times I turned it on, now is once every two times. I do not see a very good future with this phone

UPDATE 8/15: All my screen issues have been fully resolved with FW .475
So we have our own thread for the curtain now.

I think the issue is Power Management related, let me explain. If I turn on the device after being idle for a while (device is COLD) there will be no curtain issue, but if I turn it OFF and then ON right away (device is WARM) it seems the phone is entering a power save state and is not ready to be powered on again and that's when you get the curtain issue. The result seems to be very consistent with my explanation.
What I do not understand is that why this problem started happening after one week of usage, I thought it was application related but after my "safe boot" mode where no new applications are running only stock apps and I got the same result it can be application related. Also I thought that maybe the Stamina Mode had something to do with it, but it does not.
My last theory is that there is a piece of hardware that is getting degraded over time and when the phone is warm it will produce the curtain effect, if that's the case this is really bad, because the whole phone could stop working down the road. but it's just a theory.
Oh man
My experience with similar LCD issues has been around poor connection between the LCD screen and the motherboard. However, I'm by no means an expert on this.
I would definitely be claiming under the warranty for this.
I spoke with the vendor in Singapore and told me this is a known problem by Sony and they are working on a Firmware update. They suggested to keep the phone until the FW will be released in September and then decide if I will exchange it or keep it. The vendor also extended the Return/Exchange window until October so I will have enough time to test the phone after the FW update.
It's good to know that Sony has acknowledge the problem and is working on a solution.
Any chance Sony will do a firmware update to resolve this?
So it might be a firmware issue? I sure hope so

UPDATE 2
I think the problem is Power Management related, because if I leave the phone idle for 5min and then I turn it ON it will happen the issue you are seeing on the attached video. But if you turn it OFF and immediately turn it back ON again it will be fine. I think what is happening is that after 5min the phone will enter into DEEP POWER SAVE. The threshold to enter power save mode is around 15 seconds. I would say is something that should be able to be fixed with a Firmware update, but my only concern is why this problem did not happen during the first week, that behavior makes me think it's a Hardware problem that developed over the first week of usage, meaning a defective device.
NOTE: As you can see at the beginning of the video the phone has been Factory Reset, so there are no third party apps and anything wrong on the configuration.

Mine did it the first day. I noticed it did it about 3 times that day. And I agree with you it might be the power save mode. Hopefully it gets resolved.

My Z Ultra does exactly the same thing but it does not worry me. Seems to be a software glitch that should be easily fixed.
Mine happens when i am taking calls and i turn the screen on or off. Other times it is random but normally when i have been using the device for a period and then turn the screen on and off quickly after using it.
But yeah, i do not think it is an issue to worry about. If it was serious, surely the screen would be having issues a lot more when it is on and not under these specific situations?

If it's a software problem how is it possible that during the first week the phone worked fine?, even after a factory reset the problem will still be there, that means (to me at least) that a hardware issue develop during use for the first week and now it cannot be recovered

For make sure you totally wiped that garbage bro
Hi!
My phone got a broken screen, but I got a replacement device from the insurance.
Trouble is, after a while with screen on the screen seems to become hypersensitive - it's nearly impossible to enter text through the display keyboard or just to zoom and move a webpage
After switching the screen off and back on again immediately it's OK again for a while.
Anyone else seeing this behaviour? I reckon it's a hardware problem, but maybe someone has a different explanation for this problem?
(UPDATE: Here is a link to a short video of my issue: https://youtu.be/YqKW3tU4Fhw)
So I cant seem to find ANY info relating to this issue aside from results for the LG G4, but the solutions for said phone are all over the place. Some are bad screen, some are related to sim tray, some are related to water damage and battery etc. So basically, about a month after buying this phone (KIW-L24 US version), the screen started to artifact and flash in and out randomly. There is nothing that seems to trigger it. I have set the phone down on a table while on the homescreen and watched the lightshow. It is basically a mixture of the problems seen in these videos (Feat. LG G4).
https://youtu.be/gAUkXLR7eQI And https://youtu.be/QstOH66pfiU.
Symptoms:
Screen will randomly start to flicker and fade in and out. I will also get crazy artifacting lines. (Think de-gaussing an old CRT monitor or simillar to what is seen in the second video)
If i see the problems happening, locking the phone and unlocking again will sometimes fix it temporarily. Other times the problem continues after i turn the screen back on.
Sometimes the screen will refuse to come back on. The backlight turns on, and the digitizer responds, but the screen is still black. Making sure the screen really is off, I can come back to the phone a few minutes later and it will turn on. Other times ill have to hard reset the phone (hold power button 10 sec) and it usually brings the screen back to life.
Background:
I bought the phone "used - Like New" from amazon. It came with all the original accessories and even still had the film protector on the back of the phone. I may have noticed these problems after I received the phone, but they really only started to show about a month after purchase.
At first I though it could be software related as I was running CM13 and something could have been corrupted, so i did not just a factory restore, but a full reflash. This didn't solve the issue. Restarting my phone and the reflash did help, but the problem returned. The inability to turn the screen on persists through a reset and I have to wait till the phone boots again to get the screen back. Sometimes takes more than one reboot. This pretty much confirms a hardware issue right? If i put the phone on a black screen, i can see three small fuzzy "dots" in a triangle shape in the top left quadrant. Could the screen have been damaged by whoever owned it before returning it? They are not dead pixels per se, but seems more like areas where the backlight is showing through ever so slightly more. Not visible unless you are on a black screen in a dark room. Ill upload a video showing some of the issues. Any help is appreciated!
im afraid you need a new display brodar...
Seems to be hardware issue. You can visit the nearest service center to get it fixed for few bucks if you don't have warranty.
Yeah that's what i figured, i just needed conformation. I was able to get amazon to take the return even though I was out of the return period. So at least ill be able to get a refund. Ill just pay the extra for a new one this time haha.
One question : Do u have over heat problem with ur phone ?? If u feel ur phone is more than work from the back dont replace . U'll damage the new screen also . Some ppl erported over heat cpu issue with honor ! ;.

Try moving to stock once , if it fixed stick to it for few days . 99% of possible cases for hardware issue .
So better request for a replacement from huawei . but don't mention them that u bought it used . tell them u bought it new
Seems that a lot of people complain about this bug/glitch. It mostly happens with this device, specific to some carrier like s5 t mobile etc. Mostly what people face is flickering with a green/yellow nuance that covers at least half of the screen, and that happens when you set screen brightness on minimum. Some other ( like me ) also get the flickering while turning the screen on or off. So I started doing some searches over the web, and tried all the 'fixes' possible. Sadly to me nothing worked. Some of these 'fixes' are :
Turning off auto brightness.
Turning off adaptive display.
Turning off screen overlay ( found on developer settings )
Also other strange ones like removing your sd card etc. Few people say that these worked for them, but for me it didn't.
I tried booting on safe mode, and the problem was still there. I also flashed official 5.0 and the same. So the only thing left was to blame the hardware. But I was sceptical about this since the problem is not persistive, sometimes it happens, sometimes not. Sometimes it happens on small scale, sometimes it is worse. Also a lot of people say that their devices were working fine and the problem started after marshmallow update. A certain person on an online forum claims that he/ she spoke with samsung officials and they are aware about this problem and working on an update to fix this. Does this mean it is not physical problem but just a software glitch ? Hard to say, I sent my phone to different local repair shop and they say it is screen physical problem. But maybe they just want to scam me and take money ( new screen costs too much )
After going through all these, I just got the idea to try and flash an older firmware, like kitkat. And to my surprise, on official kitkat rom it still does the problem, but FAR less.
So TLDR if you have this glitch and gave up on all the 'fixes' you found online, try flashing kitkat, it might work for you even if it's not a permanent fix.
I'm sorry to bump this topic being that it seems dead. However after my own research and now my second S5 from T-Mobile. I'm at the same point as you. My research states that it's more of an AMOLED screen issue, which after a factory reset and flash of older ROM and such does make sense. However, at the same time it could be an actual issue with the screen.
It's definitely a hardware issue in my case-cold temperatures exacerbate it ie-I have no flicker issues in the summer, but get flicker issues in the winter if my phone cool's down to the 60s. The flicker goes away if I heat the screen.
It seems the lower the temp, the more wattage (brightness) is required for the display matrix to function; insufficient wattage/heat when the screen is activated, and the matrix collapses. This is why it autobrightness tends causes issues when it provides power below threshold for matrix stability.
Easiest legitimate econimical fix is ordering a replacement screen, if you have reaervations about yiur shop doing it, it's a very easy/cheap/simple process to do yourself and plenty of how to YouTube videos.
okay, I will solve this issue for yall. I have an s5 g900t that had the screen flicker issue and also when temps are cold, the screen would blank out till I warmed the screen. I fixed this issue after a year of having the issue. a temp fix which can damage the device was found by accident when I went to change out a broken rear cam. heating the screen with a heat gun during surgery fixed the issue for a while then the symptoms came back. after much much research and testing, I found the amoled screen was the culprit. I ordered a new screen and replaced it. no more issues. I took the old screen and replaced it to my other s5 which is for testing only and the screen flickered under low light and would not come on when cold. so, if you have a screen that is flickering in low light and/or wont come on during cold, its your screen. replace it and fixed. how long the new screen will last? well 2 years later no problems, yet.
FYI, AMOLED screens are notorious for this issue and the manufacture is well aware.
I have a Redmi 5 phone. I had Global Stable ROM than switched to EU Beta. Currently on 8.7.19. I had a problem on both ROM. Randomly my phone slowdowns. Or at least the screen I don't know exactly. I have to press the screen harder and the response can take 1-2 seconds. Locking and unlocking the phone solves it. What can I do to solve this problem?
I have reported the issue. Please confirm it. We need official answers because many people has this. http://en.miui.com/thread-3446668-2-1.html
OK! I'm pretty sure now it's a hardware issue! Flashed TWRP recovery which also had screen freeze problems!!!!!
Than flashed an old firmware 9.2 something and flashed LineageOS over it. Guess what? SCREEN FREEZE!!! It can only mean one thing: it's a hardware issue. It's also explains why they ignore it: because they don't want to admit it! And because this much people has this problem we can say Redmi 5 is a FAILED PRODUCT. Xiaomi should call back this devices and give back my money immediately. But I think we are just ****. They will not care about it. Maybe only the service center can do something about it but it's a long and unnecessarily procedure. I think best option is to sell the phone and NEVER buy Xiaomi again and to stop recommend to anyone to buy it.

Hi! I have this exact same problem but I ruled out a hardware issue because every time there was slow to none response, if I turned the screen off and on again, it would fix it. I've been looking for a solution and after trying many, many things I've discovered the problem was that I was using the Full Screen option offered by MI, i.e. the option to remove the three main buttons at the bottom of the screen (Back, Home and running apps) and to control the phone with gestures. After going back to the classic three button style, I restarted the phone just in case and I haven't had any more response issues in two days, I think it was a success!!
I also faced this problem for months, specially, after I changed my display as I accidentally dropped my phone a few months ago. Sometimes the screen seems to freeze temporarily, but then -
- turning off and again turning on screen
- swiping the screen (bottom-top) with a little pressure for 1-2 seconds
- slightly bending the device
Any of this three work for me.
What I think:
It's a hardware (display) issue. My newly changed display creates this. But I am quite sure, when my device bends slightly this problem occurs.
