I've got a Z Flip 4 I've been daily driving for almost a year and a half now. The folding is quite convenient, especially with quick launch apps for like payments, but the main problem is the screen cover is peeling along the crease. It can be replaced but there's no service centres in my city so I'd have to mail it
I've heard that about the screen cover specifically with the z, one guy said he replaced it over half a dozen times but he enjoys the phone so much that it was worth it.
I like the look of the folded form as well since I've been researching these after this thread, thanks for your input
