I’ve got a galaxy fold 4 that I pre-ordered, so over 2 years old. I’ve rocked it this whole time with no case and dropped it plenty of times. It’s got a couple of scratches on the hinge but has been the most solid phone I’ve ever owned. From my experience, your claims are simply not true.
That’s actually a couple versions behind. I’ve got an XCover 6 Pro for work and I absolutely love it. The notification light and customizable buttons are my favorite.
