I brought a micromax canvas tab P480 1 year ago and here is my experience .
Cons:
It is 7 inch screen but seriously it is very bad.not clear at all
Its processor has poor performance I was trying to play and hd game name subway surfers but my tab got hanged and frame drops, lags.not playable at all
Front camera is very poor you cannot take a good selfie with this 2 mp front cam.
Rear camera is also bad only 5 mega pixel which is not enough for taking good pictures
Battery is the worst.battery draining problem while playing clash of clans
