I have installed a UAC case, I got the orange one so much easier to see when looking for it. Today I installed a POY Tempered Glass Screen Protector. The case is a perfect fit on my S8 Plus, gives me some traction to hold on to it. The screen protector was an easy install, neat kit came with it to clean with alcohol cloth then dry cloth and finally some sticky sticker to dab around the screen and pick up any remaining dust. I got lucky and got a perfect alignment with the camera and other things at the top of the screen perfectly centered. So I slipped the case back on and it looks like this combination will work for this phone. As always should my case change I'll come back and edit this post. 2017-04-28 well the glass screen protector lasted almost 24 hours, I broke it this morning putting the phone back in the case. Still like the case not so much the glass protector.
