AW SS Series 4 LTE. I was surprised it happened. I restarted the clock to fix a better day, not updating, and at restart, it started fine on the lock screen, but when I entered the password, within 1-3 seconds it would just go straight to the Apple logo. Was able to force to kill it and make it restart normally, each time, but just could not get beyond the lock screen. Tried all the various possible solutions available online, but nothing worked.
Called Apple support and replacement should be here today.
