Samsung m31 is locked for 1430 minutes

[GALdevi]

So, my samsung m31 has been acting up recently

It's started restarting without any reason and even after I cleared cache and cleared some space in internal storage it didn't stop. Today all of a sudden it restarted 3 time without any agp and finally after some time when I opened the locker screen and entered my pin the pin screen closed and my device was looked for 1430 minutes. I have entered the correct pin when the device restarted by I dont know what caused the problem. I a a college student and I really need my phone so if anyone can help me I'll be grate full

TAKE IT TO NEARBY SERVICE CENTER !
AND SEE WHAT THEY GIVE REASON BEHIND THIS !
ASK THEM TO FIX THIS WITHOUT ANY HARDWARE REPLACEMENT !

Check if you have put auto restart timings please remove it. Next if you have installed any app recently uninstall. Try using device care regularly.
