I have been used Micromax Canvas Tab P480 last 6 month. it had so many problems with battery, touch screen and functions. And Some time this tab will hang. Touch respone is very poor.and Key pad will not respond. the front camera is very lower resolution.and This tablet sound quality was very harsh and rough not clear.and the tablet get over heated when you are playing game, The tablet has 1 gb ram and rom 8gb.overall good.but am not satisfy with product.
