Nowadays, every person have own communication systems but I talk about vivo y66 it is not good phone because in this phone thera are no more features like proper 2 speakers and if the person talk to another person through this mobile phone so, there are lots of disturbance due to talk so, what can they do and in this phone signal systems are also not good and mostly, people also do not used this phone. Design are also not good and it is not sleek mobile phone as well as it is very long phone but in white colour it looks totally bad I also do not like this phone
