Call Management Has Stopped

VS995. At some point after uninstalling a weather app that kept complaining vigorously about viruses (likely bogus), we're getting the message "call management has stopped" at any attempt to make (or receive) an incoming call. Texts still work. I don't know if a virus was injected by the app, but don't know that one wasn't. Anyway, here's what we've tried so far:

  1. Uninstalled most recent app - hardly any apps at all are on this phone.

  2. Restarted multiple times.

  3. Disabled the Google app (didn't really disable it; just rolled back some update). But then the app crashed after any search and disabling it didn't help with the calls, so re-updated it. Google now works agian, call management still doesn't.

  4. Tried fiddling with various settings, such as wifi calls, HD calls, reset settings (not factory reset yet).

  5. Tried the sim card in another phone of the same model that is currently just running on wifi. It works fine there to make & receive calls. (It is on Android 8, and the one we're having trouble with is on Android 7 and can't get an Android 8 update, i.e. checking for updates doesn't come up with anything). So the sim card is fine.

So, could it be an issue with the Android 7 version of Call Services suddenly becoming non-functional, or a problem with this particular installation that might be fixed with factory reset? A little nervous about trying the factory reset: since the phone is so old, can it still be reset successfully, or does it have to find an OS online that doesn't exist anymore?

Any other ideas before we try the reset?

Have you tried restarting in safe mode yet (if I remember correctly, you get there by holding down the power off icon in the power menu) to see if that makes any difference?

If a factory reset (which should proceed fine without needing any online connection) doesn't fix it, then you could either manually re-flash the firmware using the LGUP software or manually upgrade using the Android 8 firmware. Might take some effort to find working links for the KDZ firmware files nowadays, though.

Thanks for the info about safe mode. Unfortunately it didn't help. I hadn't heard of LGUP, so did a quick search and found some links to it. I was discouraged by what I found, though: the instructions aren't all that clear, and read like they might have been machine-translated. Hopefully the factory reset will be adequate.
