I purchased this phone a month ago and, the mobile sound quality whether in terms of audio as well as voice quality even in speaker mode. This device produces more sound than the recent smartphones released like redmi, etc. The device is so light to use and you will feel like you have nothing in your hand unless you have attached any back cover. I have a black mobile, which is awesome in looks and style. And there are all the features like wifi, Bluetooth, 4G support, dual sim, and etc. The camera quality of this mobile is also very good, it can focus very well and click some awesome pictures.
The mobile is a true value for money with which you can get an awesome quality of mobile, and it will be also in budget. Yeah, an even Jio 4g works excellent with this device.
The service is also very good, the persons at the showroom have a good friend talk with regard to any issue. Hope you go with this mobile, you will surely like it. Overall the mobile is super cool.
