Hi, I'm having problems using Bluetooth to play music on my portable speakers, It did work at the beginning and actually started having trouble around 2.01 firmware although it did work on this firmware. Now the audio constantly stutters unless the player is connected to a power source. I don't know what to think, I've tried all previous and new firmwares, all Bluetooth quality settings, mp3 and flac and the problem persists. Anybody has any clue or a similar problem? I've contacted Hiby through facebook and they have been trying to figure it out, but it strikes me as odd that no more people is experiencing this issue,maybe the hardware is faulty? It seems like a power routing ¿? issue.
