After replacing my screen, I’ve found out that the home button from my old screen, the connectors for it do not pair together. Also with the front facing camera that comes with the replacement screen, anytime I open Snapchat, it will crash if it is using the front facing camera but Snapchat will work with my back facing camera.
I don’t know about the front camera. The home button however may have to be reprogrammed to pair with the logic board, since Apple has a specific code for every part in an iPhone. if reprogramming isn’t an option, you can look online for a universal button that’s compatible with an iPhone 7. Though it might be a problem, since Touch ID would no longer work.
