iphone 'wait minutes" without a passcode entry or open attempt

Hi,

My phone [13 mini, with current updates and OS. has been a great phone ] was in my pocket while working outside. I heard it calling out to someone, took it out of my pocket, it was ringing the first number in my contact list. I left them a message and then the phone said that it wasn't available. ? I had never seen this screen before.

Some research showed that the phone had "locked" from too many wrong passcode attempts ! I guess it was trying to open itself just from being in my pocket while I was moving around?

I turned the phone off, waited, back on with the same screen. I turned off again waited, and did the hard restart with the volume control pattern, same result.

Lastly, I left the phone ON, waited and after the 15+ minutes it allowed me to open it with pass code, normally.

Sigh, I hope this story can help someone else. Leave the phone on !

thanks
