The Galaxy Z Fold3 5G is the latest model in Samsung’s line of foldable smartphones, featuring two displays. In its folded state, the Z Fold3 offers a 6.2-inch AMOLED display on the front, which Samsung calls a cover screen. Just like any normal smartphone display, the device can be unfolded to reveal a massive 7.6-inch home screen if you need even more screen real estate. This unusual display setup and high-end feature set, including the Snapdragon 888 chipset, puts the Z Fold3 firmly in ultra-premium territory, making it one of the most expensive smartphones on the market right now.

Display settings have knock-on effects on camera design.
To ensure that the selfie option is available in any folded state, Samsung equipped the Z Fold3 with a total of three cameras. When the device is folded, an in-screen pinhole front-facing camera can be used for selfies and video calls. When working on the big home screen with the phone unfolded, users rely on an under-display camera that doesn’t require any holes or notches in the display. Finally, you can also use the main camera on the back of the device to take a selfie or allow yourself be seen on a call.

The three cameras have different pixel counts and sensor sizes.
The 12MP main camera offers the largest sensor yet and therefore the best light-gathering ability, which should make it best for low-light use and offer the widest dynamic range. The 10MP camera on the cover has very similar specs to the standard front-facing camera on more traditional Samsung devices such as the Galaxy S21. The 4MP under-display shooter not only has the smallest sensor possible, but it also captures the light that has to pass through the display first.
When capturing selfie images and videos on the Samsung Galaxy Z Fold3 5G, you can choose from three built-in cameras. If you just want to take a quick selfie or make a video call, your options may depend on the device’s current folded state. If the device is folded, the cover camera is arguably the simplest and easiest to use option. Likewise, when it’s unfolded, the under-display camera is the most obvious choice.
But the cover camera might be a better choice when taking group selfies. In this case, the limited depth of field of the main camera means people behind can be out of focus. The overlay camera, on the other hand, keeps objects in focus across multiple focal planes, ensuring decent detail even on objects behind the scene.
