Micromax Canvas sparks 2 is a good phone in such a price. it has UI system but another Android phones there is Android one system. its camera is also good then other phones in same range. it has launcher called first touch launcher which gives a new look to the phone other phone has Android one launcher which is very basic. it is upgraded to lollipop 5.0.1 Android version. it is good because almost all the apps are running fluently. it is not easily hanged so in my opinion its very good. This mobile having 1GB RAM and battery backup is also good its 1850 m a h battery gives a good backup which impressed almost all the customers and a good phone in low budget also use this mobile from 1 year and 5 months ago and I did not find any fault in that phone
