iPhone 12 restarts and wifi and Bluetooth aren't working

Hey, got my iPhone 12 128 GB MGJA3CN/A. The phone suddenly reboots, sometimes when it boots back on the wifi and Bluetooth are unavailable, but cellular data are working. At this state the phone won't reboot by itself again, I have to reboot it manually for the wifi and Bluetooth to work again. But then again after some time, it reboots by itself again, sometimes boots back with working wifi and Bluetooth and sometimes not.

Do you think this is an antenna problem? To me, this sounds like a hardware problem with a bad contact on the antenna flex.

My hypothesis is: When the antenna somehow detaches with wifi in use it reboots itself, if the antenna is still detached in the reboot process the phone will boot without wifi and Bluetooth in use. If it is connected it boots with wifi and Bluetooth working until it disconnects itself again.

Thanks for any help, Sam
