So I've had the Snapdragon version for over a year now. There have been a few drops, but I've always used a screen protector and case, so there aren't really any visible damages. Recently though I've noticed some problems. The touch screen is malfunctioning if it gets warm (either in a hot room/outside (as it's summer and pretty hot here)/while charging). After turning on the touch visualizer in the developer settings I could see that it was registering another touch at a random place on a screen. This makes the phone unusable until I reboot it, which solves the problem temporarily. Another rproblem I have, is that sometimes a few black dots appear in the middle of the screen randomly. They just flash up then disappear. It's not a deal breaker, but rather annoying. Can anyone give a diagnosis on these problems, what could I do about it?

So I'm getting my girlfriends fascinate from her since she got an Incredible 2. The only little problem is the screen doesn't work. A little background on the problem. She woke the phone up and the screen no longer displayed all of the picture. Very little of it can be seen and it is discolored. The actual touch screen works though, you can unlock the phone if you can navigate the lock screen. The phone was dropped in water a week prior to this however it still worked fine up until the screen problem. Does this sound like just replacing the screen would fix the problem or do you think there's a deeper problem?
Hi,
I have a touch screen problem with seems like if the screen "feels" a non-existing touch so that when I actually touch it with my finger it activates pinch-zoom mode.
The problem appeared after I left a phone on a shelf switched off for about 1.5 month waiting for a new battery to arrive. When I switched it on with a new battery the mess started.
Tried the old battery, factory reset. The problem persists, sometimes right after boot, sometimes 1-2 min after boot.
From searching the forum I understand the most common problem with Hero screen it bottom freeze, but that's not my case and I couldn't find problems similar to mine.
Thanks for help in advance.
Any help much appreciated....I have an issue with my screen flickering, dimming very faint and going black when i touch my screen. sometimes my screen will go black for long periods of time and phone is practically useless. This is not an issue of just a slight flicker on light colored screens that I have read other people describe. The screen does not always do this but is definitely getting more frequent. The flickering/dimming happens when I touch screen and especially when I touch it with more pressure. It also seems to be more sensitive on the bottom half of the screen.
I consider myself as the "scientific type" and have been testing many different scenarios trying to find a rhyme or reason to this happening. The only thing I have found is that if I keep my phone out of my pocket the problem seem to not happen. Then I can put my phone in my pocket for as little as 5 minutes and my screen could be messed up for hours. Everything else about phone seems to work great.
At first I was thinking this was a software issue but now I am leaning towards hardware? I am rooted, unlocked with s-on and cannot send back for warranty. I was running mean Rom for many versions and have also gone back to stock rom and stock kernel and experience same problem. Many reboots and clean installs too. I have also taken phone apart and reconnected all ribbon cables hoping there was a bad connection.
My Evo lte is only 4 months old and has never been dropped nor has it ever been wet. There are no scratches on screen and has been in otter box since the phone was brand new. I am running out of ideas and am I dire need for advice.
Thanks,
Mike

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.
