Why screw around with those bulky Otterbox cases when you can get quality sleek designed cases from Spigen and one of there NON-Glass screen priotectors. Reviewers have said that their screen protectors haven't been lifting from the case. I was surprised how well the 'wet' application protector covered the edge but leaves room for a well designed fitting case. The only thing I'm picky about is the slight orange peel surface IF you look for it. Otherwise you can't really notice it. When you turn on the display and even a 4K video, you'd never know that it had a screen protector.
My (daughters) S8+ is clipped into the plastic holder of a Samsung S-View Flip Cover case and the protector is perfectly fine in it. That flip case is so cool because it has a glossy like see through cover that let's you see your time, texts/notifications and answer calls. It does however have a small NFC disc on the cover to turn off Always on display when you close it. I haven't tried going into settings to see if I can do something to reverse that closed-cover-turn-off feature yet. I also did just find a Genuine Samsung screen protector that's the older style clear gloss PET film w/'dry' application which they describe as being a bit curved to fit the edge better and keep from lifting. It was odd that they don't offer it here on the US Samsung sites but have it available in most other countries. I did find an Ebayer in Florida so I should have it soon.
