Waste mobile I ever used. Dead slow, Initially performance will be somewhat good later after a 6 six month. Dead slow. can't even make a call(very slow). Slow slow slow. can't play even mid-level games. No proximity sensor too. no flash. Image quality in dull light waste. It is not worth of money!! Nokia 1100 is better than this, In Which we can make call easily. Most of time whatever u type in keypad don't work. can't send even a msg properly.
