I am using vivo y55s handset. vivo make very good product but we know all product is not good. In my opinion after using vivo y55s they have very good battery backup and take about display that means display is very good and that have many new updated feature her display is 5.2 inch and her ram se also good then other that price mobile and one fault of this phone is they have call record but not autocall record we want to any call record then in call during we to tp press call record button but her camera is better they have 13 MP camera back and front camera is 5MP . If flash is very good but in low light Camera dont word proberly but in good light photo was osm . they have many types off feature like smart features, waterproof also and in one time we hate to use many thing without any problems and her look is like a I phone so I think this is best phone in her prize this is my experience for vivo y55s I hope do u like it.
