That sounds like Bullshit, I had the original z flip for a year and a half and never had an issue. Caseless and didn't baby it at all,it was covered in scratches and dents on the outside from being rough with it.

I did have one issue with my z fold,but Samsung had a courier collect it from my house and repair it at no cost.

They're not for everyone, but the benefits of a tablet in my pocket are amazing, but if you want a normal phone just buy anything else,they're all practically the same these days.
