Hi! I tried all but my cellphone just dont recognise spotify as a music player app, so if i want to pause the track i`m playing or play the next or previous track, i have to unblock my phone. Loocking for a solution I read that the problem might be coused by EMUI, and the only "solution" I found so far was download another block screen, please, bring me a real solution. I have Android 4.4.4 in case it would be helpful.
