Just because the Samsung Galaxy Fold's delayed launch caused controversy, it doesn't mean that Samsung is giving up on foldable smartphones.
In fact, according to a report from a Taiwanese supply chain, it looks like Samsung is hard at work already on the Samsung Galaxy Fold 2. Currently Taiwan is the main supplier of MIM (metal injection molding) hinges and with more smartphone makers such as Samsung, Huawei, Xiaomi, Oppo, Motorola and others looking into foldable smartphones, Taiwanese hinge makers have expanded their capacity to accomodate these demands. As such, leaks like these are to be expected. This round, the Galaxy Fold 2 will have a horizontal crease instead of a vertical one like the first Galaxy Fold. Which means while the first Galaxy Fold would open to be more like a tablet, the Galaxy Fold 2 would be more like a flip phone instead.
The Galaxy Fold will be 6.7" and will reportedly bend around the horizontal axis. On top of that, it may also have just a small 1" screen on the outside for date/time/notification icons. It's considered to be a clever and eventually cheaper to produce than the current Fold concept. Based on this, Samsung is aiming for portability instead of screen space.
A 2020 launch is expected for the Samsung Galaxy Fold 2 based on the earlier report, though not much else but the screen size is known about its specs. Rumours claim it's likely to have everything that will come with the Galaxy S11 and then some. Until then, we still need to see how the first Samsung Galaxy Fold will do.
