I brought letv 1s from flipkart, the device is good working in sound quality, camera and video watching is superb, also call quality is very fine, very stylish, designed for youth, very fashionable, battery charging is very fast , in 1hour its fully charge from 0 percent to 100percent
But some things are not good is first there is no memory card slot , second usb -c type pendrive is very expansive to expand its memory
Third, its UI is not good, and also many app stop working on this device. Also, the battery backup is not good, it can be used normally 3-4 hours.
The main thing is no memory card slot.
