I never lay my iPhone down on surfaces without something underneath to protect it; at home I usually have it on a stand, which makes it easy to see and also means it is less likely to get scratched or scuffed. I've been doing this for years, ever since my very first iPhone. I am enjoying not having a case on my new Jet Black iPhone 7 + -- I can appreciate the elegance and beauty of the phone so much more and it really feels very nice in my hand when I'm using it.
