Ringer issues with Android phone - XFinity

This question is about "Ringer issues with Android phone", with XFinity-Comcast Television Apps. App almost works too great. When a call from Xfinity Voice home phone rings on my Android cell, it kills the ringer on my cell. So I have power off the cell to reset the ringer until the next time. This is more than annoying especially when the OS decides to optimize all the apps which can take up to 3o mins. I have missed many calls til I figured this out today. Does this happen to anyone else or does anyonehave solution? Thanks
