Does the Glass Back Cover Adhesive need to be replaced on reassembly?

Hi there,

I was about to take my OnePlus Nord back cover off to test something with my vibration motor and realised that I might have to replace the adhesive when putting things back together. I am new to taking phones apart that use glue, so I wasn’t sure how this would work, especially since the Nord doesn’t require a heatgun to remove the back.

Do I need to replace the original adhesive before putting the rear cover back on, or does it fit back together without doing that using other connectors or possibly the original adhesive?

thanks,

Yannick
