Micromax has been trying to bring new phones and beat up other smart phone companies but they are still way behind and couldnt cope wid the other brands. Altought the phones are low price and offer various features bt lacks in many areas.
Canvas 4 is the upgraded version but still the camera lacks in clearity and also the phone starts to hang after 4-5 months.
The service is also poor if you go in service centres.
Better to opt other brands.
