https://www.cnet.com/news/galaxy-folds-screen-woes-and-more-how-my-foldable-review-unit-is-doing-so-far/ > Look closely beyond the bezel and you can see a thin film ringing the Galaxy Fold. Samsung says this protective layer isn't a screen saver, and you shouldn't peel it off or you might damage the screen. > These handsets are usually one of the first run but not meant for retail sales. They may not have completely final hardware or software, which means that reviewers may experience bugs or irregularities. If that happens, reviewers usually alert the company. In this case, Samsung told me that our version of the Fold is the unlocked model for the European market. US services like Samsung Pay, Bixby and Samsung Health won't work on it, and calling might be subpar because these particular Folds aren't optimized for US carriers. Fair enough.
