I got the fold 5. Two weeks ago it dropped out of my pocket (folded) as I got off a regular bus and dropped 3 feet right onto road asphalt. I had a tempered glass screen protector on both the front and back, and have absolutely zero damage other than 2 tiny dings on the aluminum frame, and had to replace the front screen protector as that one was cracked badly. The front screen had no damage after peeling off the screen protector, and the inner screen has no damage whatsoever. Cameras are also undamaged and the phone seems to have no internal damage. I personally vouch for the durability of the Fold 5 :)

I'm running this. My friend got the original Fold, and she kept using it until the Fold5 came out and got that one. She still has the original and it's in good condition, so that bodes very well.

So far I like the Fold4. The big screen is nice for videos or even normal use (I have it open as I type this), but the small screen is fine for when you just need to see the time or something, and it fits in my pocket even better than the s2x ultra or whatever did.

Edit: typo

I did see a couple of surprisingly cheap foldables on ebay, but I'm still somewhat wary of foldables and I ended up finding a fairphone 4 for a pretty good price
