Hi there. My A51 is a few years old now and has been fine, until the past few weeks. Several times a day, at random times and doing different things, the screen reboots and locks. Not the whole phone - just the screen.
The screen goes black - it takes 2 or 3 seconds to come back so I can see the fingerprint reader, and then carries on where it left off once I sign back in.
Anyone else had this? thx.
