There are unimplemented features, for example, I found some gesture functions for activate music, camera , etc with the screen off, but even when they can be activated, they don't work.
True, very pleased with this phone. Anyone suffering of occasionally reboots? It is the only thing I complain about, luckily just happens when not using it. Never has happened when in use.
I have one since a few weeks ago, not bad, the only inconvenient is that i can't root it yet. I've tried every app without success. Fortunately the android version is almost pure AOSP, with no bloatware. If you have any questions ask and I'll try to answer.
