I have an iphone 5c that has a completely shattered screen and it wouldn’t let me swipe across to unlock the phone and the screen was red and black. I was wondering if it would cause my phone to crash after some months if I used my sisters screen with the lcd digitizer, camera, and earpiece still attached out of her phone? Will that mess the phone up or not?
Yes you can use iPhone 5c with the parts on it from one iPhone 5c to another without any issues.
you can interchange parts between different phones of the same model, with the exception of the Touch ID button (on relevant models), these parts are just a susceptible to malfunction as any other parts. as long as you’ve done the job properly there should be no problems.
