I have a Samsung A13 phone that has been used, but have no PIN code. The phone is turned on, but locked. To reset the phone I need to shut it down, but to shut it down I need the PIN.
The battery is at 100%. I want to fix this before tomorrow. (I could turn on the flashlight, so I'm doing that to drain the battery.)
This unlockjournal about the A13 mentions that I repeat entering the PIN to get alternative options to unlock the phone. The only thing that happens is that I get a 30 second time out.
As @Robert suggested, I could restart the phone after holding Power + Volume Up + Volume Down for about half a minute. Then I could restart in Boot menu while holding Power + Volume Up. Then I did a factory reset and rebooted.
Guess what! The PIN is still needed, so this is not a reset to factory settings. Wiping the cache partition didn't make a difference.
Samsung knows the phone and expects an ID of some kind. It offers the option to login using a previously used Google account, but what if that is not possible?
How do I reset the PIN?
