It should still be under warrantee so I would not reload any software. If you donxxx8217;t already have desktop manager on you PC , down load it and do a backup. Then bring the phone to Sprint ant tell them itxxx8217;s defective and you want it replaced. They may resist but tell them it drops call constantly and they should replace it. New phones are usually under warranty for a year. Like any electronic device, sometimes new breaks.
