Review on 📱 Waterproof Case for Samsung Galaxy S21 Ultra - Oterkin Full Body 360° Underwater Case with Built-in Screen Protector, Dustproof & Shockproof - 6.8 inch (2021), for Samsung S21 Ultra 5G by Trey Michaels

Can be waterproof but also conversational. You cannot hear anything when your phone is in this case. I think they missed the mark when they did that. They immediately missed the functionality. The speakerphone doesn't work at all. You can just hear your entire phone vibrate when someone is speaking. But you don't hear them. And on a normal call, they're almost inaudible. The great thing about a waterproof case is that you can't even use your phone.
