Vivo v5s mobile is the product of a big chinese company. Front Camera quality of vivo v5s is very good. sound quality is best. Headphone quality of this mobile is very excillent. But hybrid slot is very bad. you can use only two sim one time or one sim and one micro sd card. Fingerprint sensor is very fast.4GB RAM and 64 GB inbuilt memory is enough.My vivo v5s colour is BLUE. So you can buy this phone feel free. #Wao.Vivo v5s.
