Ok buddy I have an iPhone 5c and I dropped it and cracked my screen I order a new screen it came I switched over the back plate the home botton and front camera put the screen in and touch not working right it shadow touches it will open up apps I don't won't to open and typing on the keyboard is impossible so I thought that I got a defective screen I returned that one and got another on again I switched over the back plate and home botton and front camera again and the screen still did the same so I returned that one as well and got another one from a totally diffrent place installed that one and it did the same thing so then I retured that one and got a screen with the back plate and home botton and front camera and in stalled it and all works great so your problem is the back plate that sliver plate on the back of the LCD that is what my problem was try that and let me know
