VIVO Y83, I just got this mobile before one year its damn best mobile. I use this mobile all over the day and there is not a single problem cause till now and it is also good for gaming all types of game is working on this device. And about its heating while execive use so it is better than other devices and in summer season also it does not get much heat. And the weight of this mobile is very less and the camera is very awesome and the problem of the battery is there not much but the I have to charge it 1 or 2 time in a day but if you r using this mobile for less time then there is no problem of charging . Thank uh
