Turning off light to a portion of the screen using ADB - General Questions and Answers

Hi team,
So I dropped my new Galaxy S10 this morning and have broken the screen. Only bumped it a little on the corner but now there is a bar of light about 2mm high that runs along the entire bottom of the screen.
Touchscreen works perfectly, but the amount of light coming through is really annoying. Is there a way to turn of a select area of the screen using ADB? I know I can use overscan/density to move everything up a bit, but I want/need to turn off the shining white light
Have Googled/searched the forums heaps for an answer and found nothing so apologies if this has been asked before

Screen Off Issue while on phone

I am having a weird problem. I am on stock ATT with root. If i am talking to someone using my phone....if i put it on speaker and screen goes off...I cannot make the screen on back again. If i click power button the phone gets disconnected. its really irritating bug.
Also if i am using GPS while driving and If i get a call....after attending the call and I am not able to go back to navigation app. it shows me black screen.
These two things are annoying me like hell. Any help is appreciated...
maybe set display to never sleep? esp. while driving? will drain the battery faster, but in the car presumably you would have a charger available...
Are you using a screen protector or case thats covering the proximity sensor? Its one of the little spots in the upper left corner. Where most protectors have a cut out. Anyways, thats there to shut the screen off on the phone when you are on it so you dont accidentally hit any buttons. If its covered it wont allow you to turn the display on because it thinks its next to your face. Either that or maybe your sensor is bad.

[Q] Dead screen now dimmer with vertical lines / banding

Hello. The screen on my wife's S4G today suddenly started acting funny. First, it wouldn't display anything, but it seemed the phone was still functional. Then, with fiddling on my part, I got it working again, first fully and now in a sub-par way. The phone boots fine - and I actually unlocked the bootloader and rooted, and in the process went through a full reset, just to see if that would help anything - but the screen appears dimmer than before and there's vertical banding across most of it. The banding doesn't completely obscure the screen, but it looks bad. One other thing I notice, and this is reported in other places, is that there's backlight bleed in the lower left corner, even when you just insert the battery, and often on booting, there's a flash of pixelated "dust" across the screen, that's brightest in that corner and fades as it spreads out.
Anyway, TMI probably. Does this sound to anyone like a bad screen, bad connector, digitizer, or something else? I'm totally new to any of these kinds of issues, but would like to save the phone, if possible. TIA.

The bottom of the screen lights up with more strength

Hi all, about three months ago I replaced my phone's screen. Until recently I never noticed anything wrong with the OEM replacement. But earlier today I noticed that the bottom of the screen (where the nav buttons are) lights up with more strength than the rest of the screen... Is there any way to fix that or do I have to just let it be?
Also, since I don't know if the problem was there right from the moment I made the repair, I was wondering if this could be caused by software (let me explain).. I use an app called Screen Filter, that acts like a screen dimmer, but the thing is that it never dims the bottom of the screen because of some kit kat incompatibility (as like in the windows counterpart software (Dimmer) when a window is momentarily above other the dim goes off for that particular window, and the moment you finally select the window all the screen is dimmed for good). Could this Screen Filter app have caused damage on the bottom of the screen, consequence of always being not dimmed while the rest of the screen was?
Thanks in advance.
PD: Since I saw the problem I uninstalled the app as a precaution and tried to reboot and see if that made the trick, but unfortunately it didn't. Maybe the damage its already done.
Is it light bleed? Some LCD panels are plagued with it. I had a replacement N5 that just got sent back to Google that had horrible light bleed on the bottom of the screen. It could just be the panel you used and you never noticed it before. An app can't damage the screen like that, as LCD panels are not susceptible to burn in like OLED is.

[Q] Charging LED

Maybe I'm just a little too picky or ocd but I noticed my charge status LED goes from a brightly lit red just before reaching 100%, to an extremely dim (barely visible) green when the battery has been fully charged. When I hit the home or power button to turn the screen on then back off, the green LED is visible and bright. Anyone else notice this?
[UPDATE] Never mind, I'm an idiot... I should've known this, the light sensor dictates the LED brightness level.
I don't know if samsung was just rushing to get these replacement devices out and had to speed through the assembly process but my device looks just that way. The overlay is noticeably off center to the left across the top where the sensor, camera and iris scanner are located. To the left of the home button there is a thin vertical line indentation as if there is a small dent on the shell of the device under the overlay.
Once again, could be I'm just overly critical, but for a device pushing the $900 retail mark I expect more. Venting complete...Still love my Note 7:good:

samsung galaxy s6 broken screen. Works fine on high brightness but flashes on lower.

hey guys,
I have a problem. Yesterday i replaced the battery and the back and multitask button on my galaxy s6. I now have a problem. I had to remove the screen from the bezel. When i did this i saw a metal like film on both the bezel and the screen. After i saw this and replaced the other parts i put the phone back together. Everything worked exept for the screen.
The screen is acting quite weird. When its on high brightness everything is fine and the screen works without any problems. But when the screen is turned off or the brightness goes down the screen flashes white.
I was wondering if there was an easy way to fix this without having to completely replace the screen. If i need to replace the whole screen i will just get a new phone.
Hope you guys can help me.
