Micromqx phines are most strong.compared to samsungs phone.as well as micromax phones system quality is batter than samsung phones.
But many peoples are uses samsung phones.my advice is dont buy samsung phone there are most rearable company xiaimi is available.
When you buying any phone compare price and specification with xiaomi phones.
This phone us with mali 450 graphics processor it is good for movies but not for gaming or other applications. Micromax is goid brand for trusting usefull phones.
