Ok, so WOW....I solved the touch playing up after several screen replacements on one customers iPhone 5S. After throwing 3 screens in the trash thinking I had a bad batch it was something so RIDICULOUS it's not even funny. The LCD shield plate (where the black soft material is on the right side) had a scratch in it that was exposing the metal underneath. Just on a whim, I covered it with a small piece of Kapton (Polyamide) tape. Voila! The theory is there was static electricity build up causing intermittent touch malfunction. This soft black covering must protect from that. This problem seriously was about to send me to the psych unit! See pics...

Do you need to remove the front display assembly to replace the daughterboard? From the images it appears you just have to go in through the back glass to do this job. Confused.

Black Tesa tape, available from iFixit store. Strongest muthaf****ing adhesive for phone and tablet repairs available. I use it on all iPad and Samsung Repairs. Never lifts or comes apart like cheaper tape. Don't use glue. Just don't.

Is there any supplier that sells the original adhesive for the edge of the phone so we can make it better? Or do we have to just wing it with some cut double sided tape etc?

You sound like the WORST tech in the world. No offence, but half your story sounds like bullshit to me.
