Green Screen - Huawei Mate 30 Pro Questions & Answers

Hey guys, new to XDA here.
My phone is currently experiencing green screen. It started 2 days ago. I have been using dark mode since I got this phone last year and two days ago I noticed that the screen color isnt as vibrant. Imagine a black screen with a bit of white color. I also noticed that the lower right of my screen got really hot.
Then I restarted my phone a couple of times and I also noticed that during the Huawei animation, green spots started to display on the screen. Also, the whole screen starts to green when unlocking using fingerprint.
I turned off my screen the qhole day and opened it before I went to sleep and the issue went away. But right now, the screen would randomly flicker and display green color.
Im not sure if this is a display issue. But I have read that Mate 20 suffers this as well. I wanted to ask here first before I bring this to the service center.
Anyone experiencing this as well? How did you fix it?
Thanks!

Ok, so my phone is experiencing the greenscreen right now and I dont think it will disappear anytime soon. I did, however, install the Device Info HW app on my phone. There is this 'shell_back' on the 'Thermal' tab that had risen to 41 degrees. Any idea what that is?

Screen randomly fades to black

Hi,
Received my Sensation about a week ago, and since then i have found that randomly during usage the screen will quickly fade to black (appears to show some kind of artifacts whilst fading). To continue using the phone i have to lock it and then unlock it again. Sometimes it happens as soon as i unlock the phone.
Anyone else experiencing a similar problem?
Any help greatly appreciated.

Hi mate,
I received my Sensation today and it took all of 10 min for the screen to go black with a thin blue vertical line through the middle. I had to take the battery out to get it back to work. But now the screen flickers, shakes when I touch it (but not always). Also now if I get the black screen I can get it back by putting it to sleep and waking it up by the power button.
Does that sound like your problem?

PS: and to all the phone is going back and I'm hoping for better luck next time around

Developed a blue stuck pixel after 5 months of ownership

Have any of you had a stuck pixel appear on your Infinity? Mine is blue and relatively near the center of the screen. I tend to notice it most often when watching videos or anything with a dark background. Ignore the dust as I forgot to wipe the screen before taking the pic. http://bit.ly/XXfale

I had a stuck pixel around two weeks ago.
It was white and toward the left side...I thought oh-boy here we go.
I forgot about it then noticed it went away after a few reboots.
Had this happen on my 6 month old notebook also and that stuck pixel disappeared after one shutdown.

I had a vertical yellow bar appear on mine. It went all the way up the screen. I was past the Amazon return window by 6 days but they overnight-ed me a new one anyway.
So far, I have run Dead Pixel Detector and Pixel Curer, both over night without success. I have also tried "massaging the pixel", both with the screen on and off. Because of the tablet's glass top layer, I'm not sure how effective this method is though. I just press down enough for a few seconds to see some flashing movement on a black background and have the "waves" move through the area of the stuck pixel. Any other suggestions or stories of a similar experience? Has anyone been able to get a replacement from Asus because of a stuck pixel near the center of the screen? This problem is the only thing holding me back from rooting and unlocking.
Has anyone else experienced the appearance of a stuck pixel on their tablet?

[Q] Screen Was Fine, Suddenly Turned Green and Faint?

Hi,
My Nexus 5 was working fine, and hasn't been dropped/damaged, but the screen has suddenly gone green and very faint. It still works but I can't figure out what the issue is. My guess is hardware?
When I say green and faint, I don't mean just a little bit, I mean a green/yellow hue all over the screen, and faint like someone has applied super high contrast in a photo editor.
Any ideas?
Phone is stock, not rooted or modified in any way.
Thanks
Leakage?

Sorry do you mean light leakage?
The phone now has yellow borders a few mils thick on all four sides, in addition to a green hue.
Perhaps
Still under warranty?

I have the same issue as of a week ago. Except mine is pink borders and a blue tint. It was fine one night, plugged it in to charge at bed time, took it off the next morning and it was stuffed!! After a day it came right but then stuffed up again a few days after that.
I'm guessing its the display but don't know why. Looks like you can get Chinese replacement ones for about 60AU$, but the procedure looks pretty full on.
Just to update, as per poster above the phone has now returned to normal after a few days. Very strange. Factory reset, cache clear etc etc didn't work, just one day started working again.
Have the same problem
I am also having the same problem. I was charging the phone on my laptop. I took it out and suddenly the screen had a bluish - pink tinge - prominent around the corners but affecting the entire screen.
Did you find any solution?
Yep as above it just righted itself within a few days. Very strange, never seen a phone have an apparent hardware issue that's unresolved by factory reset etc then just miraculously lose the problem...but that's what happened!
It definitely has to do with the display.
i changed my original display screen as it was broken with a cheap one and since then it always gets green and pink tint while charging. After sometime it turns to the normal color.
Same problem pink/blue tint over night
I bought a used nexus5 just 2 days back but it looks stunningly scratchless so its probably refurbished I guess. Any how, I put it on charge the next night of purchase with a heavy duty charger that came with my Tablet its rating is 2Amp. In morning the phone had this blue/pink tint.
Is it a problem or will it go back as most people are saying? As long as I keep on using proper charger will it come back?
OR
Should I go back and strangle the seller...?

[Q] Black Screen Problem

Hi All,
Just came back from a Holiday with the Mrs. Whilst away, the screen on her GF2 went black with only the very top row of pixels lit up. I restarted the phone and the same happened. After a few minutes, the screen came back on and was fine.
She said its happened a few times now which is concerning. Have any of you experienced this issue? (BTW, the phone wasn't hot when this occurred.)
Thanks.
LG have RMA'd this phone. Lets see what comes back, (and if its unlocked.)

My phone is semi-constantly getting this dark line down the left side of the device?

It's really weird and I have never experienced this in any Android device, but at least once a day my phone will get this line about 1/8 screen length from the left and it stays and adjusts with the screen orientation. This issue started occurring I'd say about two weeks ago. I really do not know what's going on with my phone, the only thing I can guess is that the screen I purchased when I replaced my phone screen is running faulty, but this is screen I got around December. Taking a screenshot does not show the line on the device and it is 100% not a stray hair that's stuck to the device. What can I do to fix this? Rebooting or turning the device off doesn't work.
