iPhone XR restarts randomly without any obvious reason
My second iPhone XR, paired to the newer one, restarts randomly, once a day / once every two days .. in a non consistent time interval. No message is given out when this is happening. I noticed this after the two iOS latest upgrades, now is running 18.3.1 . FYI the phone operates normally with no other issues. Any idea or help is welcomed
iPhone XR, iOS 18
