I'm not sure if it's a requirement to state if your iPhone has had it's screen replaced when listing on eBay, but I'm worried about buying a used on in case it has had a replacement screen. This is because I've seen a lot of stories about poor quality third party screens. Might be a silly question, but is this something to worry about? Do all third party screens support 3D Touch and the P3 colour gamut for the iPhone 7 and above? Thanks.
