Just faced that problem again after few days. Checked screen info and found there is no any data recorded, even tried to press buttons while in this menu, nothing appears. UPD tried again about hour after player stop/start from android app settings and that's what I found in info menu.

I don't know what it depends on, but after reboot it has a chance 50/50 that buttons will actually start to respond. I already gave player every possible permission, but sometimes I still lose control over it on smartband. Here is a screenshot of the last successful try

I faced a problem and couldn't find any solution on the Internet. When you try to change track or pause it, buttons on smartband doesn't respond, you can only change volume level, but with built-in player everything works as intended. So I wonder, is there any way to fix that problem in next versions? I really like this player, but that bug disappoints me sometimes
