"Hey everyone,

Ghost touching mostly means the screen has been putted in the phone too tight, try not to put the screws in the shield too tight. Maybe that helps."

mine is when i put the case on my iphone..the ghost touch will come..when i remove the case..problem solved..i thought my screen is problem

"Hi everyone. A week ago, I smashed the original screen of my old iPhone 5. After I replaced its original screen with a new aftermarket screen of USD10,00 from China, immediately I put on a new tempered glass of USD1,00 again from China and when I turned on the iPhone 5, almost immediately I had that ghosting that everybody describes.

The new screen was randomly selecting anything and most of the time touch screen was not responding at all. Of course I thought that the new screen is faulty or I did a mistake while replacing the old screen. I opened and replaced the screen for 4-5 times, but ghosting was still there.

After I found this topic, I noted 3-4 things that other wrote and decided to give it a chance before throwing the whole phone to the dustbin.

I did the following steps and my iPhone 5 is working like it should be and its almost 2 days now that I see NO SIGNS of ghosting! So I am quite sure that this will help lots of people and its quite easy if you have some minor experience with opening smartphones as I do :)

1) I turned off the iPhone 5 and I opened it and cancelled the battery.

2) I removed from my old original screen the 3 grey/black foam sticks behind the 3 main cables of the screen and placed them on the 3 cables of the new aftermarket screen.

3) I put another foam stick between the second and third cable (exactly above the silver fuse/capacitor(?).

4) Behind my old screen, in the middle of the metallic plate and on the left side, I removed that small white sticky circle and put it on the new screen and I put back also that pink sheet that came with that aftermarket screen.

I put back the new screen, put on the battery, closed the housing normally and switched on the iPhone.

No cleaning made, no alcohol, nothing. I only cleaned a bit the backplate before placing that white circle described at step 4.

Note that I do not know for sure which one exactly of the above is the solution (if any) or if its just luck or something, because I did all the above same time and I hope ghosting will not come back.

Hope it will help somebody out there, even if we have October 2017 and already iPhone 8 is out.

GL!

"In all the screen replacements I've done I've never seen ghost touching on an iPhone 5 series LCD.

I would say in this case it's surely got to be damage to the logic board. I wouldn't be able to tell you the location as I'm not sure what sort is responsible for that."
