You seem to be the only one in either thread that is having random reboots. Can you explain your install to me?
I do get a reboot after I flash the magisk boot image, but it's only once, expected, and happens shortly after initial boot.
I basically just followed the instructions every time:
flash crdroid boot
recovery reset
reboot recovery flash rom
reboot recovery flash gapps mind or nik, (and magisk on 16.03.2002)
boot system reboot flash crdroid magisk
It's about 1-2 hours up time before the first random reboot, then the frequency increased to every 1-3 mins. then I reinstall system and do nothing, no gapps/magisk, still reboot. While I basically installing things like magisk lsposed, root and apps from play store and few from swiftbackup, adjust some system settings, restore some backup configs like Tasker. Then the random reboots started.
I also experienced random hard crash on crdroid A12, but very rare, and it prompted error code related WIFI (and qualcomm?), like a blue screen on Windows.
The severe random reboots also occurred one peried of a time years before on official LOS for my OP7 pro, It is one generation between LOS 14-16 I guess.
No such problem on LOS 17/18
