Review on Lanhiem Samsung Galaxy S9 Case: IP68 Waterproof, Dustproof & Shockproof with Built-in Screen Protector – Full Body Sealed Underwater Protection in Black/Gray by Robert Dabney

. I liked this case EXCEPT that the screen protector scratches fairly easily and definitely drowns out the media speaker (although it's possible). In less than a year I'll be looking for a new case because I can't see my phone's screen in daylight because my own fingernail scratched it when it touched the screen protector while scrolling. He's solid in other ways. I've dropped my phone multiple times with no damage. The charging port cover does not wear out despite frequent use.
