With the latest 1.8 version I get verry often a restart, when I enable mobile data. This regression was not in the former versions - I had them all ;-)
I guess you refer to LineageOS 18.1 not 1.8 (i.e. Android 11)?
If you want to help: Is this kinda reproducible? I.e. what do you do when that happens? Enable mobile data in settings (or QS tile) and it restarts? If so do the following after installing the platform tools (i.e. ADB) on the computer and enabling developer options on the phone:
- Disable mobile data
- Connect to PC
- Run "adb logcat -c && adb logcat -b all" in a shell on the PC
- Quickly enable mobile data (the above will start spitting out uninteresting stuff too)
- When the device restarts the logcat should stop (if not: CTRL+C to abort)
- Save the output from before the restart to a text file and attach here
Hopefully there will be an error message allowing me to find your issue as I don't have it...
