Vivo y55s is a good phone but compare to the price you are paying its not worth it its just a waste of money I have baught this device recently its user interface is smoot but after one month of use you will find the phones lags and the battery drains faster .even if the phone is in idle the phone eats 15 to 20 % of the battery its just give a 4 hours of screen on time even though it has good battery . So my suggestion will be insted of wasting the money on this you can buy the redmi not 4 with the same price range with amazing features so if you agree with me please hit the like button and comment if you agree with me!
