I've been experiencing something really annoying with my S9 the past 1-2 months. It keeps on rebooting just randomly. I can't seem to replicate the issue because I don't know what causes this issue. The software is up to date, tried factory resetting it, wiping the cache and also run it in safe mode. There are days it happens like once, but there are days like yesterday, it happened 3-4 times a day.
The weirdest part is, it also happens when I'm not using the phone- so when it's on the table, couch or whatever- it just reboots. A couple of days ago I also got some weird ''stripes'' on the screen when it booted up. But those immediatley disappeared right after booting up.
Can this be a hardware failure?
All the best,
