Hello and thanks for any help in advance!
I have a Samsung Galaxy M30s smartphone which is about 20 months old. I'm not sure if it's still in warranty.
A few days ago I woke up and started using it – nothing unusual whatsoever, no new apps or messages or glitches – and after about 5 minutes the screen goes completely black and after a quick pause, the phone boots up. I thought it was just a little hiccup but then, after a few minutes, it did it again, and again, and again...
Apart from this obvious problem, the phone isn't showing any signs of being faulty. For the few minutes that the phone is actually on, it works perfectly. There's no warning signs that the phone is about to turn off. It's just a sudden black screen followed by the usual boot screen. No error messages – nothing.
It's only using 50% of its ram (2GB/4GB)
I have about 2GB free storage space (2GB/64GB)
The phone doesn't appear to be overheating
It's fully charged (So it claims)
So, here's a list of things I've tried already:
^None of these things above solved the problem^
Things I haven't tried:
The reason I'm reluctant to do a factory reset is because I don't want to brick my phone if it decides to shut down whilst it's doing a factory reset. I'm also worried that If the phone shuts down whilst I'm uninstalling apps, it may also brick itself. It also doesn't stay on long enough for me to backup some photos I haven't backed up yet. So I'm a bit stuck between a rock and a hard place.
Any tips or solutions would be greatly appreciated.
Yeah, even does it off the mains. Plugged in and fully charged. Really bizarre behavior.
Cheers for the reply!
Actually, just to add - when I plug the phone in I get the lightening bolt symbol (as usual) and then the battery percentage climbs from 0% to 100% for about 2 seconds. Is that normal? Could still be a battery problem I guess... probably good if it's just the battery
