In the bluetooth options of the Samsung mobile I have APTX activated, but despite this, when I play music through Neutron Player it tells me that it is connecting through Bluetooth A2DP (as if it did not recognize that APTX is activated in Bluetooth options). Instead, when Poweramp plays any song, it tells me if the application itself is using APTX.
In these two screenshots you can clearly see:
POWEAMP
NEUTRON PLAYER
Is there an option that allows me to know/show if UAPP is using the APTX codec? (I have it activated on my mobile)
