This is to mention that, One of My friend have bought Yureka mobile from Amazon, they delivered Buggy mobile and later I had a talk with Yu customer care with so many times finally got replacement of the mobile and later I came to know that this mobile has a Proximity Sensor Issue from YU customer care.
Finally they suggested to tighten your screws and that is also not working then they told wait for the update, so this morning I got the update and I have installed but the Issue remains same, I am requesting you guys, This Yureka mobile failed so please dont buy this mobile and the Service is worst so if someone still having the issue, please return it and refund it and that is the solution.
Dont waste your time on updating these and also we are not sure it will work. so be positive and try returning your mobile so that you can be happy.so guys try new moto g 2nd generations it is worth of money!
