I have the Spigen Slim Shell Clear case on mine. It's thin, protects pretty decent, has cutouts for everything and it's clear so you can still show the phone off. Feels great in the hand and isn't slippery. For screen protectors I use Tech Armor HD protectors. They're cheap, you get 3 of them for about $6. They're super easy to apply, you don't need any sprays or need to wait 24 hours for bubbles to slowly disappear since it's a dry installation. They also make a glass one also, it's about $10 and you only get one. I have one on my wife's G3 & my brothers GS4 and it's pretty nice. I've been using Tech Armor screen protectors on my phone for a few years now and they're just fantastic for the price. I've been using the Spigen Slim cases for my phones for a while now as well, never had any issues with them.
