My phone's radios seem to be going wonky.
Too often, my phone will disconnect from one WiFi network or Bluetooth device, and fail to connect to the next. Sometimes with a seeming catastrophic failure where the service on the phone will turn off immediately after being toggled on. I've searched for suggestions, and everything seems to blame various apps. I've removed some snoopy apps, like the COVIDaware MN, which uses Bluetooth to recognize nearby devices and times of contact, and then later "anonymously" ties them together when COVID is confirmed. This didn't help. Possibly there are lingering artifacts, or other services added that didn't get removed, or apps doing things I didn't expect.
So, I decided to start anew, and then add back critical apps, and apps that don't directly try to control the radio things.
One hesitation I had was my 2FA Authenticator app, which heretofore has been secured by keeping its data secret. In a fortuitous recent update, the app has made its data shareable with other instances of itself, so I was able to duplicate the authenticator data on my iPad. Everything else was either superfluous or backed to the cloud.
Or so I thought.
Not too much broke, but there were a few apps I added back which lost some settings, so they were a little more tedious to reconfigure than I'd hoped. Still, an hour after starting, I've got my phone back with my must-have apps, and we'll see if it makes a difference.
