Need help troubleshooting gray shadow across bottom of display - OnePlus 7 Questions & Answers

I'm wondering if there's any way for me to be able to determine whether a display problem is hardware or software. I have a gray shadow about one inch high across the bottom of my screen (see photos). I have a vague sense that it appeared after the December update, but I can't swear to that. It has been there for over a month.
Details and troubleshooting so far:
The shadow is visible to the eye, but does not show up in a screenshot (examples below)
It shows up in safe mode, and it stays in that spot even if the screen is rotated -- which makes me think hardware
But I did a factory reset, and after that the shadow went away for a couple of days -- does that mean software?
There is a flicker, and sometimes the shadow gets really dark. Could it be a system notification glitch or a malfunctioning ad?
I do use Surfshark VPN, but the shadow doesn't go away when I turn it off.
That's about the extent of my troubleshooting skills.
I did find an image from 2015 that looks similar in an OP forum but there is no indication the problem was solved.
I'm beyond the warranty period, so I'm hoping to be able to resolve this without sending it in to OnePlus and having to use an old phone for 2 weeks. The phone is a GM1900 and is not rooted.

Exact same problem. I have also noticed its relation with temperature i.e. The more weather is cold, the shadow is darker. Seems like hardware problem. Also if you reduce your brightness below 40%, shadow will go away. Have you find solution to the problem?

[FIX] Burn INs/Dead Pixels/Other Display Glitches FIX

Hello everyone,
I saw multiple threads already opened for the burn in issue (which I also have from time to time) and I wanted to share my solution with you. It is a simple video, which is changing the three main colors (RGB) very fast. Played for 5-10 minutes on a loop will erease any glitches on your screen (softkeys burned into the screen which is the most commen problem).

Hi
I don't mean to thread-crap
but....
after having discussed this issue with HTC themselves they have said its a hardware based issue
whilst its true running a slide show/video full screen displaying solid blocks of colour are likely to erase screen burn-in, the issue will still persist, the underlying cause is a faulty screen panel which must be replaced
Could you upload it somewhere? I could use it, i have a stuck pixel. It's blue on a black background, it should fix it.
I once fixed a big bright spot on a LCD TV with one of these RGB movies.
Hi duke_stix, I agree with you that it could be a faulty display panel, but however I didn't find anyone had it replaced due to that issue. And I know it is a temporary solution, but at least there is a solution

Screen Flicker/Static - faint wavy lines on lighter colored screens

Hi all
Recently started having this issue with my screen - haven't dropped it or anything either. On lighter colored backgrounds there are faint to pretty moderate horizontal lines flickering on the screen. The lines aren't colored or in one specific spot on the screen. It's hard to explain but it is similar to older projection tvs where there are those faint lines(static like) in the background.
I took a screenshot but it doesn't show the lines. I had been using Android Revolution HD 6.1 (great rom btw!!) and I've tried other roms since this began happening (thinking it was the rom) but to no avail. I'm currently running CM7.1.
Things I've tried:
changing roms
turning screen brightness up
turning on automatic brightness
turning down/off various animation settings
turning on light sensor filter in cm7 settings (helps a little)
If anyone can help it'd be greatly appreciated! Thanks for reading!
I would try unrooting, installing ruu from HTC website and see if problem is still there. If it is then you will be back to stock and can claim your warranty. If problem is gone then just reroot. This is a problem I have not read anywhere though so it is probably a hardware malfunction and would need to be warrantied.
Not a bad idea! I'll give it a shot and share the results once complete.
Installed stock RUU - screen lines still present so probably a screen hardware issue. Going to take it into the store tomorrow and see what they can do

[Q] Flickering noticed on gray backgrounds? After ICS update

Hi,
I seem to have noticed flickering on the screen specially on gray-ish backgrounds. I can see lines moving up in gray backgrounds as in the settings page.
As far as I can tell it was not present while I had HC since I only noticed it after I updated to ICS. I have never rooted the tablet and it is running on stock ROM.
Does anyone else seem to have this issue? Or is it a hardware problem?
Thanks
I noticed some rare flickering (once or twice a day) after updating to ICS, stock and non-rooted. But I wouldn't say it's consistent, nor tie it to a specific colors or actions.
Iif you could post an exact method of how to reproduce the problem, I might get a better judgement.
I seem to notice it quite clearly when the background is of a dark gray shade (like the one found in the settings page) in a low light room.
I just opened up SketchBook and painted the screen with dark gray (R66 B66 G66) and noticed the same flickering implying that it is not app dependent.
I've tried two dark gray fullscreen images, with auto brightness on and off, yet no flickering occurred.
Attached backgrounds for reference.
Yep i've noticed too... meaning that my TF101 is having the same issue :/
Nevertheless, I believe it is a software issue, probably related to ICS hardware acceleration thingy.

HTC ONE M7 Display Fault

I've searched but can't find my problem anywhere so I'm hoping someone can help.
The phone was my daughters and had a cracked screen, the phone still functioned and had no other faults.
I've fitted a complete shell including screen and everything was fine for a couple of days then the problem started. When I have a brightly coloured background the titles under the screen icons distorts, the brighter colour the more the screen distorts and shimmers. If I change to a dark coloured or B&W background everything stabilises again. It might be a coincidence but about the same time as the fault started the phone did and update to 5.0.2 from 4.x.x. The rest of the phone works ok unless a bright colourful image is on screen. I've tried all the obvious suggested tests, reducing brightness etc but nothing makes a difference. Any help is much appreciated.
I've tried to attach a photo but it crashes safari on my iPad.
When looking at the HTC wallpapers the problem is worse if I scroll down the choices it is worse on the centre and right images which I think are rain and grass, 2nd row from last/bottom, the dandelion is ok though. Would this be the screen itself, software or hardware?
I really like this phone but will probably have to go back to using my old iPhone if this is android.

"Ghosts" on the display

Hello everyone, this evening when I play with my s8 plus, i notice that when i swipe from one screen to another, there are "ghosts" goes from top and bottom of the device. The worst it is, when the bringhtness is set to center/low and bluelight sensor is on, ist that normal? I try to make a video and take the screen when I took the password. Phone is after latest update QDD, after I install it, i clear dalvik cache, after that I make factory reset. The phone after the update is little bit slower, and how i remember, befor update the antutu was showing acros 175000, now it is about 172-3000. Where can be problem?
The new video and photo what i take:

What ghosts?
Could you please draw in the picture and Mark the places with the ghosting?
Hello, yesterday I was in Samsung Service center, and they told me, that is normal display functionality. So I was going to the near shop and compare it to another galaxy S8+ and lets see the differences, my display is little bit purple, what i should do, they said I should wait to another update, but last update QDD im currently download and install it and the phone have still a little bit purple colors on some angles. PS: my phone is after QDD update more lagging than before, some ideas what I should do? I made Clear dalvik cache and after that factory reset.
If you are unhappy with a device costing 1k€ then take it back, I certainly would. I am not suggesting you have a lemon but let the retailer see the problem and if you are not satisfied insist on a new mobile. Mine, so far, is fine, zero problems (touch wood). If it misbehaves it will go back as it should.
Let us know how you get on.

Use the red green blue test under *#0*# and check if your problem exists there

I would suggest getting it replaced. However, if you have as much trouble showing them what the issue is as you are us, I doubt they'll swap it. You need to put up some solid color backgrounds and see what it does. The pics you're posting could just be banding in the original image. Not sure what to to tell you.
That's the problem when I try the service code and turn on the red, green, blue screen, everything looks OK. As soon as I go to the main screen or I go to the application menu, and the brightness is set to less than half, the problem is there. This is not a static picture, the "bubble" above moves. When I turn on the blue light sensor, so it's even worse, but if I give more brightness, the problem is not. Also, there is no problem in any application. It would be good to have someone who has s8 plus orchid gray, to check if have the same problem, or at least try setting the orchid gray theme. Anyway, when I compared it with the other s8, the display was more pink, and I did not notice the problem what I have.

Believe me. I cant swe any hosting.
What I see is a dark screen where it should be dark.
I have orchid grey and I can check something for you.
PS. I checked every single picture posted here.
BTW. On yt video the animations are very slow. It looks like you turn on the specific option on the developers setting.

Maybe it is just software, we should wait. But at the night it is really annoying.
