When the Samsung Galaxy Fold was first unveiled alongside the Galaxy S10 smartphones, the company didn’t provide hands-on time to the press to interact with the device, which is a norm. This raised speculations that the South Korean behemoth still needs time to perfect the device before releasing it in April. Yesterday, a leaked video of the Galaxy Fold further solidified those concerns, as the footage showed that the inner display has a visible crease in the middle. Apparently, that was a test device, which means there is still hope that the final unit won’t have a wrinkly display.

According to XDA Developers’ Max Weinbach, the Galaxy Fold in the leaked video was actually an AT&T test device which was being used to check if the software is fine and the apps work properly on the device. The unit apparently looked battered because folks over at Samsung have been using it for months to test out the internals and the software. Moreover, test devices do not really need a perfect display.
