First of all I would say that its a good budget mobile which gives us bunch of features variety like finger print sensor 8mp rear and 5mp front cam which really means it. Sound is too good its quite loud but clear and smooth also.3900mah Battery back up is much comfortable for a low to high user but but its not removable.it gives 2gb ram 16gb rom so that it can tackle more apps at a time and much more data can b stored coz it supports 64gb of expandable storage at last I would like to share the messy thing about it is that its not true 4g. But it can b updated further. Screen size is decent.
