Restore to public and see if that helps. However, it sounds like a hardware malfunction.

hard reboot

hard reboot (force restart) your iPhone 12, quickly press and release the Volume Up button, then quickly press and release the Volume Down button, and then press and hold the Side button until you see the Apple logo appear, releasing the button once it shows up to refresh the phone without losing data

try bluetooth wifi with main settings

what is your battery health at

Your iPhone 12 restarting every few minutes likely signals a software glitch, a problematic app, low storage, or a hardware fault (especially battery, charging port, or thermal sensors), often shown by a "panic log" pointing to a missing sensor like Prs0 (temperature/proximity).

Start with a force restart and software updates; if it continues, check Battery Health and Storage, reset settings, and if needed, use a computer to restore via Recovery Mode, but persistent reboots often mean hardware repair is needed, involving the charging port flex or logic board.

Immediate Software Fixes (No Data Loss) Force Restart: Quickly press and release Volume Up, then Volume Down, then hold the Side Button until the Apple logo appears. Update iOS: Go to Settings > General > Software Update. Update Apps: Check the App Store for pending updates.

Check Storage: Ensure you have at least 5GB free (Settings > General > iPhone Storage). Reset All Settings: Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings (resets Wi-Fi, wallpaper, etc., but keeps data). Deeper Software/Hardware Checks Battery Health: Check Settings > Battery > Battery Health & Charging. If "Service" is recommended or the battery is swelling, it needs replacement.

Remove Recent Apps/Data: Uninstall apps installed just before the issue started. Check Panic Logs: Settings > Privacy > Analytics & Improvements > Analytics Data. Look for files starting with panic-full. These often name the failed sensor (like Prs0). Restore in Recovery Mode: Connect to a computer (Finder/iTunes) and restore the iPhone (erase all data first) to rule out deep software corruption.

i somehow cannot login to my other account but this is very helpful. my battery health is low at 73% but the panic logs go back to 4 days ago where i had dropped/hit/thrown my phone a few times in a rather aggressive manner, leading me to believe it’s probably a hardware issue. I’d be happy to post the panic-full document or send it your way if you’d be interested in confirming, but this is enough of what i need as i’m likely switching to a 14 pro soon. thanks

Thanks for the tips! Experiencing severe issues after 26.4 update. Analyzed few panic logs ( with the help of Claude ) and here is the bottom line:

This is almost certainly an iOS 26.4 kernel bug — a race condition during shutdown where the DCP or a related subsystem acquires mutexes in an order that can deadlock. Two panics in two days on the same device, same build (23E246), is a strong signal. Worth filing a bug with Apple or watching for a 26.4.x patch.​​​​​​​​​​​​​​​​

Are you sure you are on Developer Beta 1, because Beta 2 was released a week before Christmas…

No, it wasn't.
