I run ARC B274 on a modern Samsung (S24) with Android 14 and encountered a problem with latest build:
Once having ARC in foreground, it stays there and does not allow the Android main buttons to appear (instead continuously showing the 4 main ARC buttons). As these three - task manager, home and back - are vital to switching apps, it is a bit difficult to ever leave ARC. In some cases it is working to open a search window in ARC as the appearing keyboard seems to force the 3 main buttons to appear and stay as well.
I am not sure which build I used for the last time, but I am quite sure scrolling up from below used to work and task manager as well as home button appeared.
While trying to figure out when exactly the Android buttons reappear and stay after using text search, a new variant of the problem evolved: Android and ARC main controls are now seemingly both appear as prioritized at the same time leading to overlap each other:
See similar with Android 13 on Fairphone 4 - android buttons appear on swipe up, overlapping with Roon controls and disappear almost too quickly to be useable at all. It’s really messy down there.
Running B275 ARC and the problem seems to be fully resolved. Android main buttons and ARC main buttons are always-on yet separated so no confusion anymore.
