Big fan of Defender, thanks to Defender my old Galaxy S5 stays in perfect condition even after years of use. However, probably due to the curved edges of the S9, this Defender model doesn't have a built-in screen protector. I have purchased LK brand screen protectors which are said to be compatible, but even after waiting the recommended time after applying the screen protector to place the phone in the case, there are huge bubbles forming at the bottom of the screen, probably due to tight fit of the Defender. Otter products come highly recommended, but with this particular model at least, you should do some careful research before choosing a screen protector.
