This Samsung model mobile has primary cannot record videos in full HD resolution and the inability to support USB OTG cable and one more drawback was the phone does not comes with fast charging technology. The absence of Quick charge is a huge disappointment, then this mobile quality of the video taken with the primary camera which is very shaky. It has the absence of gyroscope limits the gaming performance of motion based games. Users will also not be able to use a VR headset. Hope some issues will be rectified in next release.
