-The metal contacts for the antenna were missing in the frame. (gsm not working) also the threads for the small screws were missing. -One of the threads in the lower speaker area was off-center, preventing the insertion of a small metal plate and assembly of the whole phone. -Pretty poor responsiveness of the display -Notification LED "window" is a little off centre, the LED is partly hidden.
Got damaged screen and asked for refund. But they denied neither agreed to return.
