I’ve been using the Vivo Y31L for nearly 5-6 years now and it has not disappointed me a bit considering the time period when it was launched and the specifications that come with it. I bought it at a retail shop for Rs.9000 which was okay. 1 GB of RAM is good enough for a moderate user. Comes with 16 GB of internal storage, 2200 mAh battery, dual sim and a micro SD slot, 8 MP rear camera and a front camera. The screen size is 4.7 inches. The only problem I’ve faced is the camera which has lost focus apparently because I’ve not handled it carefully over the years. It has slipped from my hands a lot of times and also unintentionally. But being solid and sturdy it has stood the test of time and is still going strong. If I just drop it from 3-4 feet, nothing happens to it, rarely does it switch off after crashing to the ground which has put a lot of my faith in this series from VIVO. Awesome build quality and a body of steel (literally !).
