So, I’m dealing with a pretty frustrating issue right now. My Galaxy S20 Ultra has suddenly become almost unusable. The screen lags like crazy and barely responds when I try to unlock it. Sometimes, I’ll try to enter my PIN, and it just doesn’t register at all. When it does, it takes so long that the screen times out and goes black, forcing me to start all over again.
It doesn’t stop there, though. After finally getting it unlocked, the phone just freezes up. Apps take forever to open, and sometimes it starts doing its own thing, like opening random apps I didn’t even touch. Then, out of nowhere, green lines flash across the screen, and the phone powers off. After that, it refuses to turn on for 10 minutes or longer.
I’ve tried restarting it when I could, but it didn’t help. I looked for weird apps that might be causing the issue, but I didn’t find anything suspicious. I can’t even boot it into safe mode. When I try, it keeps turning itself on and off repeatedly.
I don’t really know what to do at this point. Can someone help me figure out what might be causing all this? Any advice would be really appreciated.
