There are two big things to address with folding phones: the screen and the hinge. These two parts are such a focus because they’re the things that aren’t yet solved problems in the phone world. It’s where the experimentation is happening, and it’s also where the biggest points of failure are found.
Samsung’s so-called “Ultra Thin Glass” is 30 microns thick, on the order of a very thin human hair. That has consequences. Chief among them: any ding or nick in the glass could be catastrophic.
Then there’s the crease in the middle of the screen. It is there, no getting around it. I can see it when I’m looking for it, but I don’t see it when I’m not. It also feels a little odd, but not so much to put me off like it did on the Razr. The screen is also surrounded by big, raised plastic bezels. I don’t love them, but I also understand their necessity and don’t find them especially annoying.
Third, there is a small gap when the phone is closed. That’s a little scary because, again, the screen is fairly fragile, and it’s a space where debris could get wedged in. (The Motorola Razr, for its many faults, managed to fold completely flat without any gaps.)
Fourth and lastly, Samsung has added brushes and caps to the hinge to better protect it from debris getting inside. That’s the issue that likely destroyed the screen on my very first Galaxy Fold review unit last April. Will these new brushes work? Who knows! They couldn’t stand up to a dust test from iFixit, but it was a very aggressive test. All I can say is that I have more faith in this hinge holding up than I did in the Razr’s or the original Fold’s.
