I have a clamshell "z flip 6" prior to that I also has the 3 and before that the 2.

I'm extremely clumsy and always drop my phone. Prior to these flips, my primary reason for upgrading was that I cracked the screen. I've never once cracked the screen on my flip because it's always inside and the case covers the entire outside when folded.

I also haven't observed any issues with the hinge area cracking on any of them. Not sure if I'm just lucky. But I do tend to sit there and stim opening and closing the phone repeatedly so I don't think it's due to my usage.

My partner is ymas keen photographer and has the fold out tablet style one and loves the big screen for viewing photos and websites, but I like the little one because it fits in my tiny pockets and purses.
