It is very strange to see different types of behavior of Google Music Player in the file explorer of my phone.
I have Asus Zenfone 5z (Android version 9). I'm using the latest version of Google Music Player (version 8.21.8170-1.0).
When I open an MP3 file named "Meant To Be.mp3" of 8.61 MB size in the folder "Ringtones" of the file explorer. This file is open in Google Music Player in mini mode (overlay style). See the screen shot below:
The same is true when this file is opened in the "Alarms" folder. And this is not just for this particular file, but for any file.
But the strange behavior starts as soon as I copy or move this file in the folder "Music" or "Downloads". Not only for this file, but for any file already existing there. Check the screen capture to know that the MP3 file is open in Google Music Player full screen mode and NOT in mini mode:
Does anyone know why this is happening so? How can I make Google Music Player play all MP3 files in MINI mode and NO in full screen mode by default? Playing music files in the overlay style is much easier if I test / check files – I can easily and quickly return to other files in the folder compared to the full player mode.
