LG IMS HAS STOPPED HELP ME PLEASE

At last! Fixed for me! Here’s what I did. I had to “combine” some of the suggestions to come up with the correct “elixir” to fix this:

First: Go to Airplane mode…

Second: Do the following:

Go to settings → Apps/notifications -> app info -> three dots -> Show System -> com-lge-ims-rcsprovider -> storage

Force stop and clear data (from Data Usage).

For me, at this point the popups stopped, but only if in Airplane Mode… If I exited Airplane Mode, they continued. So, at this point, DO NOT EXIT AIRPLANE MODE YET.

Third: Do the following…

1. Enter the code 277634#*# on the dial pad to get into Operator Hidden Menu.
2. RAT_Selection →  LTE only

Fourth: Exit Airplane Mode…. For me, at this point, the popups were gone!

I have a v20, and this is what fixed it for me.
