Among the specifications of ATJ-2135 published by Actions,... it is said that the player support OTG, no tested yet, anyway I've found the ability to be plugged in USB charging while the player is in functions. This is useful if the player is plugged to a amplifier to release the sound through external speakers.
Well my GROVEN player has capability of charge and play at the same time...
When the player is plugged to USB its needed simply to press for some second ESC key, after this the player will do the task "playlist organizing" and then it will show the menu. A small orange icon labeled USB will appear next to battery icon.
PS.: I learned how to put it in this status because is the way I put in such status my Onda VX858 and my Teclast C260... all with the same capability!!!!! :lol: :lol: :lol: :lol: :lol: :lol:
