Issues with screen with heat - LG V30 Questions & Answers

Hello fellows, i have started facing issues with my LG V30 H930's display.
It's started showing strange vertical lines/stripes on the side of display. Mostly this happens when i plug it for charging or due to the ambient heat (40+ C' these days here).
Please suggest what to do in this situation. Do you think this is permanent issue requiring change of display or can this be fixed with software?

Someone has posted the similar issue but unfortunately with no fix:

[Q] Problem Display Horizontal Stripes

Hi guys, lately I have been having this strange problem with the screen of my i9100. Occasionally it shows these random horizontal stripes, very ghost-like: link in attachment
The problem is I am completely unable to force this behavior. It seems independent of any kind of temperature, both surroundings (outside - 10°C vs inside - 23°C) and temperature of stuff within the i9100 (i tried firing up some benchmarks to cause heat, but the problem occurs regardless). The display brightness does not seem to affect this at all, being set to many levels both automatically and manually. No apps seem to be involved, or rather this behavior can be seen in virtually any app or with any background.
The issue seemed to be vaguely linked to the percentage of phone surface covered by my hands. Looked promising, but still could not reproduce the issue.
Doing the *#0*# (or similar code) and testing all the choices did not reveal anything suspicious.
This problem appears at random occasions almost daily.
The reason I have not yet applied the warranty is that I have recently try applying it to another issue i have had, the SoD, but I have been told that the issue could not be reproduced and hence it was deemed unexisting. So, I would like to avoid any similar experience by discovering how this issue can be reproduced or what might be the cause.
Note that I googled stuff like horizontal flickering lines/stripes, but what I have found has revealed nothing. Mostly I came upon a different problem with 1pixel wide lines.
So, any help in revealing what's wrong with my phone or how to reproduce it would be very much appreciated.
just if anyone was interested, device was found defective.

Issue: random black rectangles

Since the day before yesterday, after about 2 weeks since I've repaired the USB port of the SGS3, I got a weird UI thing being shown.
I see random, small, black rectangles appear and disappear. Sometimes also random colorful lines instead of rectangles.
They seem to appear more frequently when I open games, and not showing at all when using the recovery.
I've tried multiple roms (since I thought the rom was buggy), even a Kitkat rom, but I see this issue on all of them.
Not only that, but I see other issues that might be related (and they might be because of the rom) :
- sometimes the UI freeze or I have random reboots.
- Sometimes the UI doesn't respond to touches.
- Sometimes the OS goes to the lock screen for no reason.
Attached a video of the black rectangles. No idea why the video looks a bit red, as the color is ok on the device.
What can it be? And, how can I stop it from happening and fix it?
My guess is that it's a hardware issue, as it occurs on all roms I've tried (and I tried about 8 roms).
Could it be related to the USB port replacement? Maybe they did a sloppy job?
Definitely a hardware issue, and yes, it could be caused by the repair, but i think you could have a hard time proofing that.

Is there even a slight chance it's a display issue?
I think it costs less than an SOC replacement.
Most likely not.
Display issues show different error patterns than you described. Like Black or false color lines (most likely display connector) , dead or (permanent) false color pixels. I have never seen triangles.
Your issue is related to your gpu. Normally you would check for: drivers (you already did by using different roms), heat issues (can be a cause for spontaneous appearance of your error pattern, might be the case if your gpu faces heat accumulation), permanent defect as a result of overheating (eg by OC and higher voltages than stock).
Typical error patterns for gpu issues:
"artifact are defects that result in graphical anomalies on the screen as dots, centellazos, deformed figures such as triangles
or rectangles"

if it is a non permanent issue (which is unlikely). Try to cool your phone and then test for a short time. (but keep in mind that batteries don't like it too cold).
hope this gives you more insights to your issue.
I've taken the device to 3 cellphone-labs, all failed to fix the issue. They thought it was a problem with the screen, but even after replacing it, it didn't help.
The last one told me that it's something in the CPU/GPU, and that fixing it will cost quite a lot, so I chose to have a trade-in for Galaxy S3 Neo in about the same cost.

Samsung Galaxy Alpha Screen problem

Hello everyone, this happened just today. I was using my galaxy alpha AT&T and all of a sudden the screen starting glitching and jumping. I was quite shocked because I bought this phone a few days ago. Although the phone is not brand new but the vendor told me that it's completely fine. Anyhow, I pressed the power button and waited for a few seconds then turned the screen back on. This time the screen was fine but after a few seconds of usage the problem started again. Now i read on the internet that this is not a screen issue but rather its associated with phone's charging port but I'm not sure. And another interesting thing is that the screen shots are completely fine and there are no signs of glitching or flickering. Secondly also note that I was experiencing the famous "cannot charge because battery is too cold!" message and I believe that this problem is also associated with the charging port. So please if anyone is familiar with this problem then guide me. Here a video link that shows what's happening to my screen

If you have the screen on the lowest bright setting the flickering will continue. Once I put it back on auto or at a slightly higher level the flickering went away. That's at least what fixed mine.

I also had this problem before the only way to fiix this was to set the mimimum brightness to 10 in gravitybox xposed module also the dimming of brightness so that it wont flicker

I've never had encounter this kind of problem. Your problem is too severe. I think it is related to the hardware.

For anyone interested, some info about screen flickering issue.

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.

Question Adaptive brightness

Nobody but a few owners complained about "adaptive brightness" bug , issue or whatever is it !
Is this a randomly issue or is a general problem ? To me is a very annoying problem so I'm thinking to sell my phone only due to this . Several updates received didn't solved this bug so I'm thinking next major update to A12 won't solve it as well . More then that it seems OnePlus 9 , 8, 8T and Nord series have problems with "adaptive brightness" wich meening a well done display brightness in sun light but indoor or poor light brightness is dimming under absolutely low suported values .
What can I do , I'm very frustrated !!!
How is yours ? Works well ?
No problem here, auto brightness is working fine in low light / medium light conditions.
The only complaint is the very placement of the ambient light sensor and proximity sensor (upper right corner) , when I bought a new bumper case to replace the original one provided in the box I noticed a lot of dust was accumulating between the bumper and where the sensors are in the corner of the screen, resulting in lot of issues with auto-brightness and pocket detection . Now I have a very thin protective case with a better cut and I didn't had a single issue since then.
Same problem here. Every evening when it gets dark, the sensor doesn't work properly on auto brightness.
For now, only solution is the app ''Velis auto brightness'' from the Play store. With this app the sensor works fine. I reported this bug 3 times but no solution in the updates for now.
I know , I used Velis for a time but Isn't correct , common sense to use a third party apk for solve bugs phones . Since December I found only you claimed this issue but rest of owners ?
Seems to be only us ? Now I'm going to think this problem affect only a few phones !?
Hmm - I have kind of the opposite issue, not a bug though.
For my liking - and compared to my old Mi Note 5, the screen could be more dim.
Id there a way to tell the phone to tune brighteness in general lower in adaptive mode? Also for the sake of battery life...

Anyone still had this issue recently? I am suffering here and it's quite frustrated.
Yes , the problem persist although there was an major update but is diminished . It's not a big issue , now . Still exist !!!
