Vivo v7 is yet another selfie focussing smart phone with ambitious front camera. The screen is 5.7 inches and it has android version v7.1 ( Noughat) . the device had octa core processor and 4gb ram which enables the user to operate several functions at a time and the phone doesnt get hang. battery is 3000 mah . rear camera is 16 mp which is very clear and nice. internal memory is 32 gn and can be expanded uoto 256gb. The phone is very slim and light weighted . My sister is using this phoen from last 3 months and is quite happy. its better than V7 Plus . finger print sensor is rear . and can detect upto 10 finger prints . nice phone to buy.
