I fly to South America monthly, so it's 10 hours in the air each way. Poweramp gives me that stupid error that it cannot check the license and stops playing mid air all the time. Once I land, it checks license just fine and plays without a hitch. How many times does it need to check for a license? I almost never turn my phone off, let alone never reset it… The link and info above is not accurate. The program has a bug somewhere and needs to be fixed. I paid for the unlocker, it is on my phone, so as long as the unlocker is on phone, it should never have to connect to no server ever… This player is one of the best around, but my level of aggravation is just thru the roof. I just landed from Chile this morning and I could not use player and I am going to China in 2 weeks… Get your act together, this is not rocket science. NEXUS 6P RUNNING STOCK ANDROID NOUGAT
