Q: phone display

Trade it in to Apple? Probably not. But, you'd have to ask Apple directly.

Hi

The terms of Apple's Renew (trade-in) program partner in the US include, under the Display evaluation section:

"We do not accept:

Devices containing counterfeit or third party parts

Devices with unauthorized modifications"
