The closed display halves almost touch, and that can smash debris into the screen.
I have my launch fold 3 and I love it. I’ve dropped.it a few times, mostly from waist height as I sometimes miss my pocket. Last weekend I dropped it from.shoulder height and it landed on the case, well half case as the other half broke a while ago and I never replaced it. It’s still fine. It doesn’t open all the way but I think that’s dirt amd debris that has made its way in and clogged the gears. The only thing holding me back from the fold 5 is the likely price. I had hoped a pixel fold would be somewhat cheaper than a Samsung but oh well. Life has changed a lot for me since I got my phone so affordability is more of a concern now. That’s not to say there’s not lemons that still come out, see the story were commenting on, but from my expierence folding phones are there now.
