Hi!

I updated my S21 to One UI 6 on 28th December - on 31st December my phone froze with green pixels and restarted - I was worried that was the end of it but it restarted and was OK - crashed once more, and a couple of times on 1st Jan.

Then on 2nd Jan it just kept crashing and restarting, and is now at the point when it is just stuck on Samsung logo. I have looked online and I have tried;

• Hard reset (can only get it to buzz, go black and then restart to Samsung logo)
• Wipe cache partition (only been able to get into recovery mode that once)
• Letting discharge and recharge
• Connect to laptop (won't recognise it)
• Can't now get to recovery mode or safe mode

I feel like I have tried all online advice - if I could get it to connect to something to check the data is there and try and remove it I would. But I can't get it to turn on/off properly, connect to anything or do anything that Samsung logo or reboot to Samsung logo.

At my wits end! Is this a One UI problem or a hardware issue?
