This Vivo Y55s is average phone but according to its price this is not a good phone I think.
Here are the features
5.2 inch HD display
6.0 android ( Marshmallow)
1.4Ghz Qualcomm snapdragon
3GB ram
16 GB internal memory and expand till 256 GB
13 MP rear camera
5 MP front camera
2730 MAH battery
According to the features tge price is really high this phone has only 16 gb internal memory now a days 16 gb is nothing for storage every phone must have atleast 32 gb of internal memory.
Battery is not sufficient this phone will die after usage of continous 5 hours.
You can purchase this phone but I dont recommened this phone because lots of other phones are avialable at a good price with good features.
Thankyou
