Since I am using Gionee S7 mobile, would like to share my experience. here we go
First of all its style & design which is very attractive and slim, easy grip for hands.
Sound quality is awesome. It’s user choice while use it with or without ear phones.
User friendly interface.
Front and rear cameras are also good installed with diff. controls but I like the most is magic focus mode.
Supported with ROM storage i.e. 16 GB is quite low but sufficient for us.
Finally the product is made for smart human beings and really value for money, everyone’s choice. Try to use it.
