Thank you for the rapid response, Arthur. You’re very welcome. I presume IFixIt sources these strips from a common supplier, also serving competitors. These multi-piece strips have very fine hole, notch, and angular details demanding a level of placement precision not easily achievable by adhering them on the back cover first — especially if intended to restore a level of water resistance. Ifitit stands out above it’s competitors, as the kit was excellent. It might further differentiate itself by provided a template to nest into the back cover first, creating a guide. Again, thank you for your product and support. Excellent.

My set of adhesive strips were a mirror image of these pictures, meaning the strips when solely attached to the green plastic liner were arranged to adhere to the back cover, not onto the phone! This is likely a production issue with the green plastic liner and clear plastic backing being swapped. Like in these pictures here, the seal strips stay aggressively with the green plastic liner upon pealing off the clear plastic liner; however, they were then an incorrect mirror image when trying to position then to the phone. This forced me to painstakingly use scotch tape the position and secure edges of the green plastic to the phone first (sticky side of strips facing up), and then lower the back cover down onto the phone, to adhere the strips to the back cover first. Then, lift off the back cover to removed the green liner, exposing adhesive to apply to the phone-side. Trust me, I didn’t install the strips upside down, or mirrored. This is just the way all my strips came, and there was no other workaround.
