i have been using this as a dd for a while now. putting in my 2 cents... overall not bad, some of this may be mentioned above but
bluetooth issue - WILL connect, not audio in call (earpeice/spkr/bluetooth) until bluetooth is off/not connected.
wifi - have noticed a few times that i wasnt connected while in range (could be me parinoid...)
no caps lock button (keyboard map/keyboard backlight works fine)
gps works for me with no issues.
no camera (gallery works but fc when camera app is running)

Thank you for your help!
