When it comes to the integrity of its products, Apple is always extremely rigorous. The apple brand does not support modifications or repairs by a third party. This will void the warranty. However, the giant of Cupertino has decided to relax its warranty policy for the iPhone. Having the screen replaced by a third party no longer voids the warranty according to MacRumors.
Many users go to third party repairers to get their iPhone repaired. Indeed, these unauthorized speakers offer far more affordable prices than those of Apple. In order to limit these types of practices, the manufacturer cancels the warranty for all of its modified devices by an external person.
Now, the Cupertino brand makes an exception for the screen of its smartphone. An unauthorized professional (or yourself) can replace it without voiding the warranty. But beware, certain conditions must be respected.
If the modified iPhone has a breakdown unrelated to the replacement of the screen, the warranty remains valid. Insofar as the malfunction directly affects the panel, the warranty is void and Apple does not take charge of the repair.
