As the biggest tech company to throw its hat into the ring, many were eager to learn about the Galaxy Fold when Samsung introduced it at Unpacked in February. When closed, the phone has a secondary 4.6-inch display that serves as its "cover," with all the usual features you'd expect on a phone. When you're ready for something bigger, the Fold opens up like a book to a 7.3-inch tablet. The Fold also has six cameras. On the back, there's the same triple-camera setup as the Galaxy S10 and on the front a single 10-megapixel camera. In tablet form, there are two additional cameras inside: a selfie camera and an 8-megapixel depth camera.  

As exciting as it looked during Unpacked though, Samsung has hit a snag during launch. Pre-orders have already begun, but after a handful of tech reporters documented screen issues like screen breakages, flickering and, bulging with their pre-production review units, Samsung decided to delay the Fold's launch in the coming weeks.
