Foldable dual screen phones seem like a solution in search of a problem. Samsung patents reveal what the company engineers believe might be the right problems to solve for a successful foldable phone.
As we saw before, providing gaming controls on the second screen while gameplay runs on the other screen is the most obvious solution – it’s the Nintendo 3DS, but reborn as an Android phone.
The patents also talk about using a stylus – the S Pen presumably. Graphics artists often draw on a stylus-enabled tablet that is not a screen – having a separate screen means you don’t cover up the artwork with your hand or stylus. This is especially important when you have a small surface to work with (like, say, on a phone).
Each half of the phone also has its own camera and speaker, which may enable other uses. The rumor mill has been telling stories about the Galaxy X phone and despite leaks and patents, there is still no official word on when the phone may launch.
