@dungphp 4.3 version is amazing.I use the one with gapps included and i don't have the freezing phone moments anymore.
The only 2 things i can complain (but just a little): on bt earphones, if i try to call the last number (click 2 times on play button), even if i hear the click(or voice, depending of earphones), it's not start the call. The function is helping me a lot while on bicicle.
The 2nd one is that the sound volume while listening music is a bit too low.
I hope you can look on this small issues, if it's possible.
Thank you again for your hard work
