Speck Presidio Clear.
Relatively thin, shows exact color of phone, & rated for 8 foot drops.
I bought mine from the local AT&T store...
A bit more than Amazon, but they will swap it out for free anytime for the life of the product.
No questions asked.
I got one new one because I scratched the back & another because I snagged the soft “gelatin” type strip right in front of the lightning port on something and stretched it.
I usually go naked but currently using a Spigen Liquid Air Armor (black) case with a Spigen GLAStR Slim tempered glass screen protector. I cannot speak highly enough of this combo.
The case is super slim, grippy and it feels like I have neither a case nor a screen protector on - it's the closest thing to going naked as I've seen. And the protruding camera is no longer an issue - I can type while the phone is laying flat on my desk.
