Hi,
At least on my unit, the fingerprint sensor was actually retained in the back of the unit and came loose from the camera lens assembly during back cover removal, so I did not need to undo the connector for it until after I had removed the back cover. I was kind of worried when this happened since I thought I tore the cable at first. May want to note that buying a new fingerprint sensor adhesive piece is a good idea, it's like 3 bucks on here.
Also, this might just be me but I would really have preferred more reinstallation details other than "hey reverse these instructions". The aftermarket rear covers on here do not come with the adhesive all preinstalled, only a few pieces of it, so you have to carefully check and make sure you put those on and alignment isn't easy to figure out if you don't know what you're doing. I did alright on that part, but the back cover I bought has adhesive that's too thin and didn't seal everywhere so I will have to redo that and the fingerprint sensor adhesive next weekend.
