A rooted FP4 running stock 11 is performing a soft reboot after entering the initial PIN for screen unlocking right after unlock the SIM. Logs are inconclusive apart from from a few Java exceptions (mostly NFC-related and one systemui-related (om.android.systemui.statusbar.phone.LockIcon.getIcon(LockIcon.java:174)).
This happens with both Nova Launcher and Quickstep.
Any hints even for further root cause analysis never mind solutions are highly appreciated. I can provide more info if required - just let me know.
How did you install Magisk? I currently run stock OS with Magisk (though without any modules, was just curious after temporarily returning to stock) and do not experience any problems. Did the update to 25.2 just today.
If you didn’t choose @hirnsushi’s path and flashed the boot.img instead, maybe it’s worth a try. You would have to remove Magisk first and return to the original boot.img of course.
