What Android version it has?
Also do you regret replacing the stock unit with this Android?
I mean I am only confused because of iMiD thing, kind of a guy who wants every single thing in working condition 
The problem I am facing with stock unit is first of all its speed is very slow. Then back camera takes seconds to engage where it should engage in less than a second, and camera output is poor + laggy. Lastly the sound quality is pathetic.
I am looking for Gen II version of this unit. That was better than this. I posted ad for it even on facebook. But haven't received any responses yet.
