I have couple more days left on my 14 day return policy and still haven't completely decided to keep. One major problem I'm facing is my Sennheiser Bluetooth headphones keeps disconnecting after like 15-30 seconds. For example, I play a song via rdio and then it stops all of sudden. But the Bluetooth connection is still there. Is this the phone problem or maybe even the rdio app? Can't figure out. Thanks for input.
