New York (CNN Business) First there was Bendgate. Now there is ... Foldgate?

Several reporters with early access to Samsung's Galaxy Fold — a luxury foldable smartphone that turns into a tablet — say their new devices broke after just a few days of use.

Reviewer Mark Gurman from Bloomberg said his "review unit is completely broken and unusable after just two days in." In a series of tweets, he documented how his screen broke after he removed the protective film on the screen. Meanwhile, The Verge's Dieter Bohn called out a "small bulge" on what he said was a defective hinge.

Other reviewers have indicated a constant flickering screen. The reports unnerved investors, and Samsung shares finished 3% lower in Seoul on Thursday.

The company announced Wednesday that the Galaxy Fold had sold out on its website, though it declined to say how many phones had actually been sold. The smartphone will be available on AT&T and T-Mobile starting April 26. It's unclear as of now if the issues with the reviewers' devices could hurt ongoing pre-sales.
