I've looked everywhere and I can't find no help. im having a issue with my phone, i was playing music i download and all of a sudden my phone restarted itself. upon reloading it it's not unlocking. i can type 2 digits in and it says incorrect password. if i type my pin or a random combination of 4-6 digits the screen flashes black and goes back to unlock like nothing ever happened? i cant unlock via samsung as it says there was a problem and i cant check anything has been hacked because i cant access messages to reach my two step verfication. someone please help with a fix? it's driving me insane. i cant even turn off the phone. only soft reset which i can't access the Recovery mode.

 

I've had a look and it seems it's the exact same issue as the pixel lockscreen loop bug

 

i haven't tried recovery mode yet, but my phone has just died so im going to try now but should be able to access it

 

Anyway of saving a backup of my phone beforehand? not everything is saved to SD card but i'm in recovery mode now
