We haven't even found out when exactly the new Galaxy Z Fold 2 is going to be available, yet rumors about other upcoming foldable models are already circulating on Twitter. Details are quite skimpy, but it looks like Samsung plans to finally add S Pen support on next year's flagship foldable, while the highly anticipated sub-US$1,000 model is supposed to integrate a cheaper screen protective layer. Moreover, there apparently is another model, which is getting a screen that folds both inwards and outwards.
