This is a cover for the front of a cell phone (in this case suitable for the Samsung Galaxy S20 FE). 
 

When using this cover, playing the game HITSTER is possible without the operator of the phone can see the song info. Only the PLAY button (to play the scanned songs), the X button (to return to the scan screen) and the bottom bar are visible.

To make the model usable for other phones, adjustments will probably have to be made.

Recommended material is TPU
