NP! I do not know what's the bluetooth version of the device, but upon checking the bluetooth function, here's the only possible detail I was able to retrieve (aside from the name of the device):
The device or should I say appliance was manufactured in 2013.
I found two alternatives instead: DLNA and Miracast. I can even stream on youtube. But still I wanna know if my FP2's bluetooth is having trouble or it is common with other FP2 owners. As I can play with my other phones without lags via BT on the same external device.
No problem with transferring files via bluetooth, streaming is the only problem.
