Can you use Iphone 7plus screen on Iphone 7?

Ah, but there's more! The fingerprint sensor on all TouchID-enabled iPhone is not interchangeable in the regular sense. The component on an individual phone has a custom signature and is 'married' to that specific device as part of the 'Secure Enclave'. If changed, TouchID will no longer work. And since such a failure implies unauthorized modification, any warranty or support is forfeit: Apple will no longer service the phone.

Let’s start from the beginning: You have an iPhone 7, right?

You would like to use an iPhone 7plus screen connected with the 7 internal components, right?

The answer doesn’t change: NO, sorry.

No, they have different specs.

They're not even remotely the same size.

As already stated: NO, it’s a matter of different specs between the two screens AND other internal components.

If you are talking about trying to build your own phone, then you are on your own.
