How can I test the screen without disassembly?
**NOTE: I have an S6 Active. This is the closest device I can find.**
I got this phone fully knowing about this problem but I took a chance on it because the price was right (free) and I didn’t have to deal with a Google FRP lock. While I decided to try my luck with it, I lost and it happened to me… Sort of. I asked how it corrupted for the previous owner when I got the phone (which is reasonable so I know what to watch for) and the whole screen did it. In my case, it’s doing it in segments and intermittently for a few seconds.
As I use the phone during the day around the house as a PDA to test the screen, I’ve noticed the image distortion the previous owner talked about more then once after hours of use. I let it go as a software glitch the first time. However, it happened more then once so it’s a deeper issue. I’m not sure if it’s the display IC on the flex cable (requiring a new screen) or a board defect (The SoC is also highly suspect) so I’m wondering if there’s a way to test it without taking the phone apart AND without damage. In my case, I have no choice because Samsung added insult to injury by making it a destructive teardown >:(. I don’t want to remove the panel until I’m 110% CERTAIN it’s bad AND I have one to replace it with since I can’t get a pull because it’ll also get destroyed. What a horrible design flaw.
Is it even worth fixing this phone or should I hold it for parts and find another phone? It's horrible when the phone is warm.
It wasn't easy to get this photo as I had to use it until it glitched but I did it. This is what it does:
PS: I tried to treat the burn-in but the display glitched out. I didn’t have concerns about creating additional damage because it was already there but I stopped to keep it from getting to a point it’s permanently defective.
