I am having issues with the phone app. This morning, it starting doing this thing where the phone rings, but no answer screen pops up. Fortunately, I've been able to accept calls from my watch. Also, I upgraded to Android Pie a few weeks ago, and everything has been working great. Now, when I do accept a call from my watch, the phone screen is just white (no animations), and looks very basic, with only buttons to end call, mute, and keypad... no video call, etc, Any idea what could be going on?
