The quality of the camera is still very low. Apart from this, once you turn off the Bluetooth, you must restart the phone so you can turn it on again. Also, when you raise or lower the volume, the volume bar does not disappear from the screen until you touch the screen. Finally, from time to time arrive notifications that appear on the screen and do not disappear once a time passes, they stay in the middle of the screen until you press the central button.
