Dropped Galaxy S7 Edge... Screen Flickering Issues - XDA Assist

Hi. I dropped my Galaxy S7 Edge and now the screen won't stop flickering, but let me go into more detail about that. My screen is fine with no problems in Always-On-Display. When I restart my phone, it flickers a lot but when it gets to the carrier (Verizon) boot up animation, it's fine. After that, my phone won't stop flickering. The only way to stop flickering is to set my phone's brightness to the highest and even then, the screen does some weird animations. It kind of looks like the screen is getting projected.
Is there any way to get this fixed?

[Q] Weird Contrasty Colours after Boot

So I just got my Galaxy S6 64GB Black two days ago and I've noticed the screen becoming very contrasty just after boot, then after I lock and unlock the device, the screen returns to normal. It's a bit hard to explain, but when the screen becomes "contrasty", essentially colours close to black, like a dark grey becomes black.
I've attached a screenshot and a photo of the screen, as you can see, the keyboard's background would actually appear black in the photo, unlike the screenshot. Has anyone else experienced this? It seems to happen only after booting up, and goes away after locking and unlocking.
I'm using an Optus Australia branded device, it has their boot and shutdown animation. I've also tried doing a factory reset, problem persists.

Ahh thanks for letting me know. At first I thought it was some weird hidden feature Samsung has employed to save power on their AMOLED screens, was digging around the settings trying to turn it off.

Upgraded to Marshmallow (BTU UK ROM) Now slight yellow tint to display.

I have just upgraded my S6 to Marshmallow, I noticed straight away the screen now has a slight yellow tint,
this was not there on Android L, it also seems to lack the same sort of contrast it had before.
I asked a few friends to check theirs and the same thing has happened, I have tried a full wipe etc and messed with the display settings but still the same.
When you first turn the phone on, you see the Samsung Logo, it starts off a nice white and then you see it turn yellowish.
So something in the software has changed, I wonder if it is just the S6 that does this? Is it too stop screen burn from the blue pixels or have Samsung gone all Apple and gimped the screen to make the S7 look better?
Also adapt display > modepreviewtablet has gone in marshmallow!, although I didn't have to do this on Android L.
Either way I'm frustrated now.
My S6 (920I) has not had the screen change at all when updating...
Mine is exactly the same as it was on LP, no change and absolutely fine, now BTU UK MM.
If you watch your phone carefully when you switch it on, look at the Samsung logo and it starts off a nice white and then it gets a slight yellow tint.

I agree, but the same thing happens with Lollipop.

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.

Samsung Galaxy S8 Plus Lockscreen

Hello, just recently bought the s8 plus and just today the lock screen on my S8 plus won't stop flickering on and off. I turn off the phone with the power button but shortly 1 second after the screen turns back on and the continues to flicker on and off constantly, also when I have my AODs on it won't load the AODs screen it just jumps back to the lock screen and flickers. If this helps my S8 plus fell in my sink with a little water inside I cleaned the phone thoroughly with a small cloth to get any water out.

Galaxy S9+ Black Crush

Hello, I bought a used S9+ but the screen seems to have black crush issue. If I keep it on max brightness, the colors seem fine but not perfect. It does not turn off the pixels while displaying black, but while showing Always On Display, it does turn off the pixels. Sometimes when I unlock the phone the colours appear normal for a second or two but it goes away again. And also the battery drains very fast and is almost unusable without a case. I get like maybe 5 hours of screen on time. Will reverting to an older version help? I am currently on Android 10 with the latest security patches. Will installing a custom rom help?
Bring the phone to a service center and have it checked.
