LG g7 Thinq can't answer phone calls

[Android Central Question]

When I receive phone calls, the phone rings, but the 'icons' to answer the phone never appear... Having the phone unlocked or not, makes no difference.

restarting the phone names no difference.
I did install Nova launcher, thinking it might have been issue with Nova, I switched back to standard launcher..no difference.

Bring the phone into your carrier and ask for assistance.
