Poor Wifi reception
Micromax devices(except for Canvas A1 which is from android one program from Google) seem to have problem identifying cellular signal providers. They take a lot of time to latch on the cellular network. In this process they sometimes hang or show no signal.
Poor screen quality.
Poor build quality.
Micromax needs more time and training to make good handsets. I guess they entered the market too early and too amateurishly.
For now I dont recommend this product nor any other Micromax product.
