I've got a Motorola XT560, which has seen almost no support in terms of roms/mods, and the root process is actually stolen from another phone. I was surprised it even worked after the process. Anyway, it seems, just like with my old Captivate, the bluetooth bitpool value is very low. The audio quality when connected to my car stereo is incredibly poor to the point of painful. Reminds me of sub 128kpbs mp3's back in the early 00's.
I saw tons of discussion on this, but the only fixes seemed to be a new Gingerbread ROM, or were for ICS and above. Does anyone know if I can push the audio.a2dp.default.so for ICS that has a modified bitpool maximum to Gingerbread? Or is there another way to improve the BT audio quality? Thanks!
