I himself is an user of Micromax canvas selfie 4. I have found some cons of this handset and a lot of advantages. If you trust upon me I am truly speaking that:-
CONS.
1) battery backup is really very poor
2) and it is not so good in its outer interface
3)Its not a 4G Handset rather a 3G handset.
But there have a lot of advantages.
1) both front and rare cams are of 8.0 MP with both front and back flash.
and I am truly speaking both cameras are outstanding.specially the selfie camera. And one highlighting feature of this handset is its professional photo shooting option in the camera. Its really heart touching.
Others if I should mention are the a hand set of 1GB RAM, 8GB of storage that is expendable upto 32GB. HD display with 720×1080 resolution, and
most highlighting feature is Mira effect which will allow you to set the screen colour according to your own way. Actually in a word it gives you freedom to enjoy your freedom of feeling the Android experience
