The good news is I now know how to do a factory reset on my phone. The bad news is that didn’t solve the rebooting problem and it deleted everything in my calendar which deleted everything in my desktop Outlook calendar when I synced it without thinking about the fact that I do two-way syncing which deleted my Outlook calendar. And my phone is still doing crazy reboots daily.
Apparently, the Universe thinks this whole concept of non-attachment is one I’m still needing to learn.
