I think it is one of worst tablets I have ever came across. it gets hanged every now and then. never resets back to original factory restore no good action or high graphic games are compatible with it.
I think there are several cons, the 2MP camera is total waste since it doesn’t support any video call apps. and the hardware switch, had issue with the switch to switch on and off. and apps in google play 80% of apps will not support even if its 4.0 ICS since its Karbonn.
In short it is total wastage of money.
