Been there, done that….
I hate when that happens !
I just ask Google Home “Where is my phone?” Lo and behold the thing starts ringing. It’s like magic! :)
My wife has a smart watch that can make her phone ring, even if it is turned off.
Oh dear, all this smart talk!!!
My dad is in a rest home and keeps his cell phone on a cord hanging around his neck so he can get it easier. One day I noticed it was gone ,but he didn’t know where it was ,so I rang his number and it was in his shirt pocket!
