I have an iPhone 8 that needs a battery replacement, and opening the device also means replacing the display adhesive.

I have 3 leftover iPhone 7 display adhesives, and I was wondering if they would fit on the iPhone 8 so I don’t have to order a display adhesive. Thank you so much!

just from looking at the 2 adhesives, it doesnt look like they are interchangeable. look at this iPhone 7 Display Assembly Adhesive & iPhone 8/SE 2020 Display Assembly Adhesive sorry my friend
