Microsoft Surface Duo and Samsung Galaxy Z Fold 2 are folding phones. Samsung’s second-generation Galaxy Fold provides a large and flexible OLED panel, while Microsoft has taken a more traditional route on the Surface Duo, providing two independent 5.6-inch screens, which form an 8.1-inch display after folding.

Which folding phone is better? The following is a comparative evaluation of the various aspects of the Microsoft Surface Duo and Samsung Galaxy Z Fold

Design aspect

Are two monitors better than one monitor? Microsoft Surface Duo is equipped with a double-layer 5.6-inch PixelSense AMOLED display, the display is wrapped in strengthened glass, and there are large bezels above and below the display panel. The entire device is extremely thin, with a thickness of only 4.8 mm, making it the thinnest foldable phone ever.

In fact, the Galaxy Z Fold 2 also has two displays, which are more reliable than the fragile plastic substrate used on the original Galaxy Fold. The device has the same 120Hz dynamic refresh rate as the new Galaxy Note 20 Ultra, and is 6 mm thick. It will be much thicker when folded than the Surface Duo.

Both phones have exquisite hinges: the hinge of the Surface Duo can rotate 360 ​​degrees and can be stopped in any position. The Galaxy Z Fold 2 can also stop anywhere along its path, although it is restricted between folding and opening, so the internal screen can be laid flat.

Camera aspect

Galaxy Z Fold 2 has Samsung’s foldable sports triple camera, and the telephoto lens has the advantage of 2x optical zoom. As for the Surface Duo, Microsoft has made it clear that this phone is not mainly used for selfies. One of the screens has an 11MP, F 2.0 camera above it. This means that if you want to take a photo in front of yourself, you must fold your phone back.

Microsoft emphasized that the Surface Duo’s single camera still uses artificial intelligence and computational photography technology to achieve techniques such as shallow depth of field portraits and dedicated low-light modes. That being said, if we expect Surface Duo’s camera quality or features to be close to Galaxy Z Fold 2, then we are lying, it does not seem to be the focus of Surface Duo at all.


Surafce Duo uses last year’s Qualcomm Snapdragon 855 chip combined with 6GB RAM, while Samsung Galaxy Z Fold 2 uses the same Snapdragon 865 Plus chip as the Galaxy Note 20. Galaxy Z Fold 2 will also support 5G networks on all major networks, and you will definitely not be able to find it on Surface Duo.

Battery aspect

Microsoft only built a 3577 mAh battery in its first Android phone, which is small compared to the 4500 mAh in the Galaxy Note 20 Ultra.

The first Galaxy Fold has a 4380 mAh battery. As the demand for power from modern flagship products increases, Samsung has increased the battery capacity of the second-generation Fold to reach 4500 mAh.

Surprisingly, Samsung incorporated wireless charging support into the original Galaxy Fold. Unfortunately, the Surface Duo does not have wireless charging or NFC, which is very disappointing given that it is also expensive.

Software and other functions

Microsoft hopes that Surface Duo developers can discover the hardware features that dual-screen phones lack and use software to make up for it, allowing users to always focus on work and help you work smarter. As for the Galaxy Z Fold 2, Samsung has expanded on the first Fold’s beautiful application continuity function, so when the user turns on the device, the application opened on the external display will be moved to the internal screen for closer inspection.


The Microsoft Surface Duo starts at $1,399 and comes with 128GB of storage. If you want more storage space, you can upgrade the phone to 256GB for another $100, because it does not have an expandable microSD slot.

The Samsung Galaxy Z foldable phone is expected to cost $1999, has 256GB of storage space, and does not have a slot for microSD storage expansion.
