Conversely, I've been using foldables since the Z-Flip 5G. The screen protector on that phone did start coming away from the screen after a few months, but I actually traded it in after 6 months and got the Z-Fold 3. I never had a problem with the folding screen of that phone, and I kept it for a year then traded it in for the Z-Fold 4. I've only had that phone for 2½ months but so far not a problem with it.
The camera and the battery life are never going to be as good on a Flip device as on a candybar. However, the SoC in the Flip 4 does a really good job of optimising the power usage and even though it's a small battery, it lasts a lot longer than you'd think.
It all depends what you're looking for in a phone.
