A second rate class administration of vivo. They just supplant things no repairs. I have Y51L.Before 2 months some how my telephone fall in water then I went to principle administration focal point of ahmedabad they said mother board must be changed yet I retreated then telephone was working with no issue. Be that as it may, on this Sunday my telephone exchanged off naturally so I went there again and they r saying the same. In any case, when I went to other shop of repairing they said just programming updation is needed.my telephone is under gurranty period so I went there however they r saying they just supplant no repairing at this administration center.so I will propose you not to purchase any vivo telephone. They dnt repair anything they simply supplant and the supplant quality is 80% of the telephone.
