Compare the design differences between Microsoft's patented Surface Duo 3 and Samsung Galaxy Z Fold 4

The Surface Duo 2 has been around for a while, and it's a significant improvement over the original dual-screen phone. Microsoft will hold a Surface event in October for the Surface Pro 9 and Surface Studio 3, but it won't include the company's next-generation Android phones.

While we still don’t have a possible release date for the Surface Duo 3, it’s set to arrive in 2023.

We have no confirmation if a foldable Microsoft phone is in development, but previous reports suggested that the Surface Duo 3 was indeed in the works. Now, we've discovered a new patent application that is further proof that Microsoft is very interested in joining the growing foldable phone market.

The patent application “FOLDABLE DISPLAY DEVICE” focuses on foldable devices, indicating that the design can be applied to Surface Duo 3. The application, filed in 2021 and published earlier this year, details a very promising handheld foldable phone.

As you probably know, the Surface Duo has two screens with a hinge in the middle that allows them to rotate. Microsoft is developing its successor, which is believed to be a single-screen phone. In this patent application, Microsoft discusses a single foldable panel that can rotate from zero to 360 degrees.

Images from the patent application show a foldable phone that can switch between a seamless tablet and a one-handed smartphone. The idea could be quite radical only if Microsoft can create a new user interface optimized for this form factor. According to the filing, the foldable phone's display can bend inward and outward.

This is interesting because phones from companies like Samsung only support inward folding with the second display on top. Microsoft's idea is to allow the Surface Duo 3 to flex inward and outward, something Android manufacturers haven't tried so far.

Of course, a patent doesn’t necessarily mean that a Surface Duo 3 with this design is imminent, or even likely. However, the patent gives us a better idea of ​​what the company is thinking, and it's possible that a similar design could be used for the Surface Duo 3 or future devices.
