Its been three years now I purchased this product and im still using it.i purchased it for 21, 700 when it was newly launched.its specifications are:
1)5.25 inch touchsceen with 720*1280 pixel resolution
2)8GB internal memory expandable upto 64GB(in which 2GB of memory is already occupied by the system)
3)3G support
4)8MP rear and 1.9MP front camera
My experience with this phone was good at start it started lagging after some months of use.its a 3G phone so you may find it of no use as 4G is in market now low picture and camera quality.it frequently says memory is full and blocks all other my application use until I free some space.the internal memory is so less that u cannot have applications of large size in MBs I can hardly install 7 to 10 apps and then too the phone gets lagged and gives low performance.its giving me battery problem also.i cannot have my data on now the battery goes super down if I turn on my data even for a 10mins span.
