Orihalcon

Hello there, I used Poweramp on my S3 till I got my new phone and everything was fine there. Now on my G8141 with firmware up-to-date it happend that the binding for my headset buttons for next / previous track are not working. I can't use the option if it is single, double - triple tab or hold to switch track. It seems nobody else had experienced this issue cause I already checked the FAQ, forum and Google without a match. I wonder what's the problem. Maybe someone can help. Greetings
