Right now i dont have time to downgrade to 4.1.2 and test it out so if anyone could shed some light on this i would appreciate it.
Hopefully someone has a solution
I tried replacing the A2DP bluetooth file using root explorer with the one from 4.1.2. Also tried replacing it with the KitKat one from my Nexus 4. They either literally broke bluetooth or just didn't make a difference in sound quality.
Hoping this can be sorted sometime soon because I've been unhappy with my phone for a while now and don't really fancy waiting for Kit Kat. There's more likelyhood of me buying a HTC One before this problem ever gets solved.
Hope I'm wrong.
