This is the fourth year that Samsung has launched a foldable screen smartphone.

Systems and Features
Samsung Galaxy Z Fold4 uses a new taskbar design to provide an interface similar to that of a PC. It can quickly open frequently used or recently used applications, and can easily and quickly convert full-screen applications to floating windows, or convert the screen Split in two to handle more tasks at the same time.
The screen splitting function can open up to four different applications at the same time, and also supports Flex Mode.
The Samsung Galaxy Z Fold4 supports the S-Pen function, which can be connected through Bluetooth to provide multiple functions, such as hovering commands, the pen tip does not need to touch the screen, and can be operated while hovering on the screen. The most commonly used notes, image capture, translation, enlargement, etc. are provided, which are very useful in daily use. However, like the previous generation, the S-Pen needs to be purchased separately, and the fuselage has no place to store it, making it slightly inconvenient to carry.

When the screen is unfolded, the battery life test is run at 50% brightness through the “PC Mark” app, and the power drops from 100% to 100%. 20% takes about 9 hours and 25 minutes, and the battery life is average. If the positive and secondary screens are used alternately, I believe the battery life will be longer.

When shooting at night, the image is still clear, the exposure is high enough, the noise is not obvious, and the color reproduction is high.
Shooting with a wide-angle lens in sunlight, the detail is good, the color reproduction ability is strong, and the layers are clear, but the dark details are average.
When shooting at night, the detail drops a lot, and there is more noise.
