Replacing the back glass of an iPhone 11 Pro is similar to the process for the standard iPhone 11. However, as with all recent iPhone models, the back glass is integrated with the phone's frame and other components, making it more challenging to replace compared to older models.

If the back glass of your iPhone 11 Pro is cracked or damaged, it is strongly recommended to take it to an authorized Apple service center or a professional repair service. Apple offers an official "iPhone back glass replacement" service for the iPhone 11 Pro, and they have the expertise and specialized equipment to perform the repair properly.

Attempting to replace the back glass yourself can be extremely difficult and risky, especially if you're not experienced in phone repairs. You risk damaging internal components, disrupting waterproofing seals, and voiding the warranty.

To ensure a proper and safe repair, it's best to contact Apple or an authorized repair service to have your iPhone 11 Pro back glass replaced professionally. They will have access to genuine replacement parts and the necessary tools to perform the repair correctly and preserve the device's original functionality and water resistance.
