Iphone unavailable
About 2 weeks ago, i lost my iphone, but could find it again with the "Find my" option on my macBook. The person who had found it gave it back to me.
A few days later, I got three times the "Unavailable" message although I had not tried to enter my passcode (I use face recognition too).
I finally did a full reset, and had no problem for about ten days. This morning, my iphone was blocked again, this time for one hour !!!, while I had not tried to enter my password (nor used face recognition).
Could it be that some external program is trying to access my phone? And if so, how can I get rid of it?
iPhone XR, iOS 17
