I've had the 7t since October 20th. And I have not yet been able to bring myself to carry the phone without a case on it. Does anybody here do that? If so, where do you get the balls! Lol.
I always run a case, phones are too slippery for me to trust. Check out the "Poetic Affinity Series for OnePlus 7T". I got the "Clear/Black" case from Amazon. It provides protection without feeling bulky.
