Hi I am using Vivo Y55s since last three months I bought it as a secondary phone for gaming and other media purposes I have to say the phone is very good with its performance.If you are looking for a phone which can click good selfies and other pictures then dont waste any time go for this phone it is really amazing.I bought it for 9000 Rs from my friends shop and the phone is valued for money, however if you use it ahove the ram storage then it lags sometimes because I play usally games of big size that is more MBs.The design and the build quality of phone is also nice however I recommend to buy a case cover.
The one thing I liked about vivo is that it provides freebies like waterbottle and other stuffs I got a water bottle free with phone
