I bought a Lumia 620 3months back and feel it is is the lousiest phone I ever had. Battery backup is very poor not even 8hrs with full charge and the system continuously hangs up. and when I complain with the customer service department they give some lousy excuse
Buying Nokia is like Buying a windows PC but without any software's,because the software's for mobile windows are simply not available (unlike android which has lots and lots of games and apps).
