Micromax Canvas FIRE A093 is a good budget oriented smart phone. It has a 4.0 inch screen , 1.3ghz quad core processor, with 512 mb of ram, 4GB of internal storage, and it is a 3G device.It has dual speakers in front of the smartphone which delivers a good and loud audio output.
It has a 5MP rear camera which is able to clock decent pics. In front it has a VGA camera which is satisfactory, it has a 1750mAh Li-ion battery which gives a good battery backup.
Some of the problems that I experienced were: -
-heating issue while charging
-occasional lags
-sometimes completely hangs and you need to restart your phone
As per price is concerned it gives a good performance with good features under 5k.
