while using galaxy s6,touch inputs may not be recognized well on edges of screen.Help me?

To prevent Mis-recognition or wrong operation by hands when holding the device, Samsung galaxy S6 is designed that unrecognized part is intentionally placed on edge of screen.

As a result, the device may not recognize touch inputs close to the edges of the screen, which are outside of the touch input area. However, the device is not faulty but its normal operation.
