Bought MICROMAX CANVAS HD a week ago and it seems it has some issues and problems according to my personal experience.
Major issues:-
1> Its touch sensitivity is a major drawback. while scrolling or sliding over screen it accidently opens up apps or drags.
2> Its auto rotate is not so responsive. while using auto rotate it does not rotate screen immediatly and it is required to shake phone vertically and then horizontal to rotate the screen.(while switching between apps)
3> It has no task manager installed by default.should be downloaded one from play store whichever one you like.
4> Accelerometer is not even so smooth. While playing game like temple run 2 it seems that i have to also tilt myself completely with the phone to move the character.
5>No update options availabe for jellybeans 4.2.(Now). may be availeble in near future.
6>Phone UI hangs when a message is recieved.(for 2-3 secs)
7> Sounds cuts or not audible on either sides when on call.
...... and might be more to find out......
