It is the most cheaply phone having facelock facility . It is very op( outstanding performance) the quality of face lock its never hang! U can use this phone ase gaming and many othe works its Camera quality is also Very Cool. Yeah its Ram is 3gb and internal storage is 16gb its somehow less a bit but if u can use it it is awesome.! Its processor is also good. You can enjoy ur android smartphone life in it even I m using it. Its battery quality is also Good enough! So its Easy to handle the phone doesn't get too warm little bit sometime it get such as in pubg 2hours it will get warm but its Ok. You have to handle that its not a problem! So go on your nearest Store and have a Try : Vivo y71 ( 3gb, 16gb)
