Hey Micromax canvas express 2 is a very good phone. It is a affordable phone I can say. Its has a best features and with trustable brand.
The camera was so good with 13MP which gives awesome HD photos and video recording was also so good.
It comes with a RAM of 1GB but DDR3 it means its equal to 1.5GB normal DDR2 RAM. Octacore processor makes the phone to run much faster without any issues.
The battery backup was somewhat good but as it is a smartphone one can use it which was a very budget phone. Overall a well trusted brand I can say.
