I agree, Samsung dropped the ball. But the writer also dropped the ball and is being a bit obstinate. It was a special order phone in a special color. If he would have stuck with something more normal at the time, and not a special model of a cutting edge phone that .05% of Samsung owners actually own, furthermore in a color that another small percentage own, he likely would have had no troubles getting it repaired at any of those stores. But that doesn't take these "authorized centers" off of the hook, even soon after COVID when parts delivery was scarce.
Look, I feel for the guy, but he literally bought a high-end Lamborghini from an online dealership -- and at a time when most businesses had issues getting parts. And he never bothered to send it in for repairs, as was an option.
i live in Korea and work around Samsung management (not in phone division) almost every day. They all have Fold 4's given to them for free by the company. Soon they will all have Fold 5's. I also have Samsung stores all over the place, so I have confidence in being able to fix something the same day that I need it fixed. So I'm spoiled. But even with all this, I don't have any interest in buying one of these folding phones because of the demonstrated screen issues people have had. I'm surrounded by hundreds of Korean univ students (mostly Flips) who have these things and I see the screens crack and break in the middle at the fold, the edges come up, and enough things wrong with them in 2 to 3 years that I don't want one until I see a few more years of non-breakage.
Resale is a pittance on these things because of the 2 to 3 year screen breakage. Samsung is offering ridiculous trade-in deals (in some countries, you can trade a Fold 4 to a Fold 5 and pay just $100, as Marcus the YouTuber talks about). They are desperate to lock people into this new form factor (and I would argue they WANT to sell phones with a shorter shelf life, as they last too long, these days).
