Hello, Note 9 exynos here, currently on EvolutionX 7.5 Android 13
my phone screen literally has a hole in it, but that doesnt prevent from using my phone.

the major issue im facing now is that if i lock the phone or let the screen timeout, the screen will not turn back on, but the phone is definitely working because i can receive messages and calls. i can even feel vibration whenever i try to put in my lock screen pattern, whether it was a fail or a successful unlock.
only way i can get it to turn back on is to force restart (volume down + power button for about 8 seconds), then it would work fine, until i have to lock the screen/ screen times-out.
other minor issue is i cant use the screen below about 60% screen brightness, the bottom half of the screen will be completely green with max brightness ( i can understand that is a hardware problem since i have a hole in the screen).
the confusion is, i never face the screen backlight not turning back on again after it goes off due to screen runtime when im in TWRP.
i was originally on Noble rom 2.7 no problems, Noble rom 2.8 no problems, updated to noble rom 2.9 started facing this problem but it was intermittent, i started rolling back the versions but the problem continued, i tried switching to EvolutionX, same problem.
Am i right for thinking this would be a driver/software/firmware issue?
Does the screen flicker, then shut off when you try to switch it on? If yes, its most likely the display. My Note9 has a busted screen and does the same thing sometimes, and at a lower brightness it flickers badly. If not, it might be a driver issue of some kind, but I would guess its the display at fault still, since OLED damage does get worse with time, and perhaps when you switched to Noble 2.9, it coincidentally got worse right after you installed it.

it does indeed flicker before it turns off, but since this post, noblerom 3.0 launched, although its not perfect, the screen does atleast work now, not everytime but the screen will eventually turn on after 3-4 tries. sometimes even the first time i use the fingerprint scanner.

The wife took her AT&T S6 Active in the pool today to grab a quick pic (for the thousandth time in the two years she's had it) when it reset, and now it's having all kinds of crazy random screen tap inputs without being touched, randomly rebooting, and even doing this:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
(I don't know why, but I can't get the image to embed to save my life. Tried 3 different hosting services, no love. WTF, XDA?)
Anyway...if the pic didn't work, it's a blue screen talking about how custom OSs can harm your device.
So yea...sure seems to me like water damage. How is this a thing?
Nvm. I'm nuts.
The blue screen talking about custom OSes is the download mode warning. It should say something like press volume up to continue or volume down to restart. If you didn't intentionally hold home and volume up, some buttons may be jammed.
I've had the same issue just from having it in the bathroom when I take a QUICK shower. It's water "resistant" basically, and the water "proof" feature is pretty give-or-take. Honestly, my S4 Active seemed much more durable when it came to water; maybe that was due to the rubber piece that covered the charge port, I don't know.
I wouldn't intentionally get it wet anymore and would look at it more as a feature to protect you from accidental damage from this point on. I know that it sucks because we bought this phone due to the fact that we wanted to do things like this, but I've had so many issues with it at this point that I'm just thankful it's still working. The screen taps (I have the feature enabled where I can see where I tap the screen, a small white circle, so I could physically see the ghost-taps all oveR) and random restarts... it's all gone away by now, but my phone will still randomly shut off at times. Even worse, it will boot back up with a black screen; I can hear the sound and it's all running, just no screen. Sometimes I'll have to force-restart it up to TEN TIMES to finally get the screen to come on.
Be thankful it's still working at all and, as much as it sucks, I'd treat it like any other "water is death" phone from now on.
I've noticed these lines appear on screen when my finger touches it. Horizontal lines appear, they seem to actually be in a fixed location, fading away after a second of no contact and then reappearing in the same location.
I have tried:
Restarting
Booting into safe mode
Remove screen protector
Changed screen brightness
Went into developer mode, there was a setting there to show where you press and it was turned off already.
Anyone know what on earth it is?

This must be a hardware problem. If you're still under Huaweis warranty, send the phone in for repair.
Hint: print the photos you made and put them directly beside the phone, so the repairman can see the problem.
I had the exact same problem and they disappeared after a couple days.
I noticed that this lines appears after I activate "glove mode", but when I disable it, reduces the lines. Only stops this "bug" after a restart. Verify if you have glove mode on (settings > smart assistance > glove mode)
I got this problem too. Very rare and I think it's a hardware thing.
A colleague of mine made the screen do this when touching it but if I did the same nothing happened. The effect (he had) on the screen went away after a few tries.
I blame it on static electricity but might be something else...
I have a similar problem except I have 3 faint white vertical lines running down through my screen, barely noticeable though, so im not sure what the problem is
?
Anyone have further information? Im worried sick because I got this problem a couple hours after puting a "smart case" (cheap knockoff) on the device (has a magnet on the back and on the side) and a "glass" protector. I'll remove these for now and see what happens.
UPDATE: I'm almost certain it had something to do with my cheap screen protector (I haven't removed it tho). In any case, it took about two weeks before these lines seemed to stop appearing. Haven't seen them for 2 or 3 weeks now.
Electrostatics

White stripes (or lines) on the IPS displays appear as a result of electrostatic voltage. This problem has been confirmed for a number of smartphones other manufacturers: Huawei P10 Pro, Sony Xperia XZ1 and XZ2, HTC U11 and U11+.
for example, Sony says:
Sony Mobile is committed to providing the highest standard of product quality and customer service for all of our products. Due to the characteristic of the display, you may see stripe patterns as a result of electrostatic in some models. This is not a functional defect and usually the stripe patterns fade away as the electrostatic disappears.

"Electrostatic voltage is still just voltage. Materials that can store electrostatic charges are insulators (or are insulated by something), so the charge cannot leak away."
IMAO, this problem is not a global one, but it seems to me that it is related to hardware defects in the assembly of smartphones.
Just wondering, if you are talking via a voice call using the speaker phone function, should the screen remain on? Mine turns off after a few seconds on speaker phone mode.

mine too!
Yes, display settings are adhered to.
You can easily reactivate display when needed...
Yeah, I thought so. So my Note 8 and the wife's , the screen turns off when in speaker phone mode handsfree after about 30s .Started doing that after porting into Sprint, so probably a software bug with the Note 8 self configuration of when changing sim to different provider.
So basically, my screen turns off in speaker phone mode after 30s. I knew it didn't behave like that before .

I'm not referring to how long your screen time out was set to.
I'm asking if the screen stays on indefinitely when in speaker phone mode.

As already answered, the screen will stay on as per display settings, if you set display to stay on indefinetely, in speakerphone will stay that way, I do not see why it is so confusing for you…

I already understood what you were saying in regards to the display time out duration shown in attached screen shot.
However I was under the impression that the screen stayed on indefinitely when in speaker phone mode regardless of what the screen time out duration was set to.

It was about a couple hours after high-noon and the sun was about 45° above the horizon. I noticed that if you hold your device with the top edge facing the sun, the screen unlock doesn't work.
It just happened to be, I was holding my device at the normal angle I hold it at, and I was facing the sun and I couldn't unlock my phone using my fingerprint unless I faced the device's screen towards me; It would give me "The screen is dirty" error otherwise.
If anyone else would like to try and replicate this and see if it happens to them too.
I think the problem must be the sun is reflecting at a weird angle on the screen or passing under your finger print under the glass and it messes with the sensor.
Update:
I just remembered it was at an angle where you could actually see the hole in the screen where the fingerprint sensor can see

The fingerprint scanner is type of camera that captures and compares images, so I'll go out on a limb and say it most likely didn't work due to too much light hitting the sensor preventing a clear image from being visible, so for security purposes, it couldn't verify your fingerprint, which I'd rather knowing that it works well than it taking a crappy scan of my fp and passing it off as okay.

I noticed sth like that in the top left corner. Not sure what that is but it's not visible all the time so I'll keep observing.
So sir you mean that is not a problem? Cz this thing doesn't happen all the time...only in the low light brightness.....so idk what should i do?

Is it your problem like this? I've noticed it always in the right top corner, specially with the blue light filter on.
The interesting part is that if I get the brightness any higher it disappears.

Well it's not a faulty pixel, the screen is not damaged or anything. You can try to use your warranty but in my country warranties don't work for such negligible and insignificant issues. Heck, in my country you try to use the warranty for a minor issue and Samsung service refuses the repair saying your phone was "pickled" with water while it never was.
I'm gonna keep it that way.
i dont think samsung uses dc dimming, so on a pwm screen it shouldn't have that kind of distortion. Sounds like a screen issue.
All A71 and S10 lite appear to have this defect. I already changed mine twice and both have the defect. I've seen cases where the device has been changed 3 times, and came with this defect every time. But it is a difficult problem to detect, so many people claim that their devices do not have this defect. The problem is usually only visible in some shades of dark gray, such as the image shown below. To check it is necessary to decrease the brightness to between 5% and 10%, go to a dark room and put this gray image in full screen.
My screen is just same as yours
