    Since you have the phone for only 10 days it could be that the battery still needs calibrating. Use the phone until the battery is around 5% then charge it full again.. Do this for a few days (I do it for a week)

    If the back button isn't working, the best thing to do is bring it back to the store, so they can check and if necessary, replace the device :)
