Limitations
-Graphics hardware acceleration it's not available due to lack of drivers from Motorola. To workaround this, I included an option to disable HW acceleration per app.
This can help some apps, but can be worst for others, you need to try.
-Video Camera - The builtin Video Camera app don't work yet due to a problem with video encoder. To workaround this, you can use many applications available in Play Store like Video Illusion.
-Fingerprint reader it's broken in Jelly Bean due to lack of compatible drivers. There's no workaround.
