Disconnecting the Samsung Galaxy S8+ Battery

The spudger tool has a pointy end and a flat end, it’s not clear which end should be used. Furthermore, the flat end is too wide to insert into the area shown, so the pointy end would seem obvious, but there is no clear indication whether it should be used to push any tabs in the area referenced, which I couldn’t find any, or if you’re meant to just sort of pry it in there until the area pops up, which is what I had to do. Then use the flat end of the spudger to lift it up gently after releasing, or popping the opposite side up as well.

Unlike its smaller sibling, the Galaxy S8, this model's assembly is tightly attached; not easy to remove. I tried different ways. The one way that worked for me was to

1. pry a little on the small notch (in the marked area on the side with the Power button) using the tip of the pick, then

2. lift a little that part, sufficiently to insert a opening pick as support, then

3. used the flat edge of the pick to pop free that side of the assembly. Then

4. used the tip of the pick to pry on the little notch on the opposite side (the side with Bixby and Volume buttons) to release the assembly.

You have to slide it out a little in order to disengage the small plastic clips at the top of the assembly from the frame.
