So after using my fold 3 for about a month with no case I can absolutely testify this phone is really solid. I had the unfortunate mishap of this phone sliding out of my pocket as I got in my truck which is lifted by the way. I knew I had messed up the moment I heard 3-4 click clacks followed by silence other than the loud thumping of my heart and the sweat drops running down my face..
Miraculously no screens were broken and this device is functioning as it should with no weird sounds coming from the hinge. My phone made it back from battling the ground with very minor scratches.
I have confidence in samsung making this devices better and better after each and every upgrade.
Anyways that's my 2 cents.
