Chosen Solution

I have two iPhone 6s 32gb phones. I broke the lcd and digitizer on one while hiking in the mountains. Fast forward. I took the logic board from the phone I broke and put it into the other iPhone which was activation locked. Everything worked except the screen wont respond to touch but the home button works (call this screen one). I took that screen off and replaced it with a screen I ordered off amazon and it causes the iPhone to overheat (call this screen two). Now…I took screen 1 and hooked it up to a completely different iPhone logic board I have (6s 64gb) and it works just fine just like it does with the activation locked logic board. So screen 1 works fine in one phone, but doesn’t respond to touch on the other. Screen 2 works fine in a different phone but overheats the board on the same phone that screen 1 works fine in. Any ideas as to what would cause this?? I have two screens and one works in one phone but not the other and one screen works vice versa. Its very irritating!
