I don't know how to describe it but it seems like the a10e is in a state of both navigating and inside an app. It can be temporarily resolved by opening the navigation again. Very weird. I have tried to cause it again but I can't, it just randomly happens. I have android 10 with one UI 2.0. I have had it for a while (3 months) and this glitch has been happening since I updated to one UI 2.0. I just wanted to show this since so many a10e users are now updating to One UI 2/ Android 10.
