Touch stops will stop working occasionally
So I got this iPhone 5S in today that I am completely stumped on, the touch will work perfect and then suddenly it will stop responding until I smack it to the palm of my hand gently and it will immediately start working again. I have tried 3 different LCD assembly's all original apple parts and tested for functionality on another device. The same thing happens. Any ideas?
