iPhone 12 mini randomly crashing (kernel panic) since 18.0. Wifi and Bluetooth disabled after that

[fanta]

I am running an iPhone 12 Mini and ever since i upgraded to 18.0 i keep getting random full crashes / hard reboots of the phone, no matter if i am using it, what app i am using and event when its just sitting locked on the table (happens 5-15 times a day in total).

The screen will freeze for a few seconds, then go black, then reboot into the lockscreen. After that reboot, WiFi and Bluetooth are disabled. When i reset the "network settings", wifi and bluetooth will work for some time - until the next crash... Then i can do this all over again.

I have tried the most recent beta, but no help.

I am seeing panic-logs in the settings app, but i am not technically knowledged enough to interpred those.

Does anybody have any tips, before fully restoring etc?

It sounds like a frustrating issue. You could try performing a factory reset after backing up your data, as it might resolve software conflicts. If that doesn't help, contacting Apple Support for further diagnostics could be the best option.

If you have access to a Mac, you could first try installing an IPSW file over your existing installation (Update, not Restore) and if this does not help - restoring it with your computer, bringing it to the latest stable public release.

I have downloaded the IPSW for the current beta.
Will restoring via itunes/finder really allow me to update the current installation with the same version while keeping my data? Im just familiar with using it to restore to a stock ipsw and then maybe apply my data from a backup. I'd of course like to keep all my data and setup.
