Hi I am Mayur.
The Vivo Y55s ia an average phone it is not too good and not too bad also. The network and sound reception of this phone is very good. It is user friendly also. But sometimes It hangs very badly otherwise it works good. The features in this phone are also good. It has 3 GB of RAM and 16 GB internal memory in it. The rear camera is of 13 MP. These are very useful features for a user. The battery life of this phone is also good. The customer service is good they always there to solve the customer’s problem. But the durability of this phone is less and the price of this phone is higher than other phones with same features.
So I recommend to buy the better phone than Vivo Y55s with good features and low price.
Thank You.
