The phone vivo Y31 is having comfertable price of nearly 8000 rs. Im using this phone from nearly 1 years. The phone has many problems like battery backup, hanging, Ram. But its camera clearty is Good so that’s why I prefer this phone. Only it’s camera clearty is good but phone has many problems. It’s Battery work nearly 5 hours only. And if you’re running 5 to 6 app the phone is automaticlly start hanging till we restart the phone. Even when we run the internet on the phone it’s start hanging. So according to me that phone hasn’t have much function so please don’t buy this.
