The Samsung Galaxy Z Flip and the Motorola Razr are competing for the throne in the foldable phone world in the United States. The two smartphones are both clamshell foldable phones that fold up and down. In the United States, the Razr was released first on Feb. 6 and the Galaxy Z Flip debuted on Feb. 14 (local time).
The Galaxy Z Flip is focused on portability. It has a small 1.1-inch screen on the outside when folded to allow users to check basic information such as the date and time.
Controversy over screen flaws that occurred before the official launch of the Galaxy Fold is unlikely to happen for the Galaxy Z Flip. Unlike existing foldable phones that use plastic polyimide (CPI) film on their displays, the Galaxy Z Flip uses ultra-thin glass (UTG). Because UTG is stronger, wrinkles that occur when folding and unfolding the phone decrease, making displays safer from scratching.
The clamshell foldable phone features “free stop folding,” which allows users to fix the displays unfolded at various angles. In particular, it can offer the “flex mode” that splits the screen when the device is unfolded at a certain angle. For example, when taking a selfie with the Galaxy Z flip at 90 degrees, you can check your face on the top screen and adjust the camera mode on the bottom screen. When fully deployed, you can take advantage of the "multi-active window" feature, which allows you to use two applications simultaneously.
The Galaxy Z Flip is loaded with two cameras next to a small 1.06-inch screen. They are 12-million-pixel cameras. The front has a 10-million-pixel lens.
The strength of the Razr is its design. It feels nostalgic with a "retro" design similar to Motorola’s most popular folder phone Razr in the past. When folded, it has a 2.7-inch screen that shows the time and battery status. When unfolded, a 6.2-inch screen appears. When the Galaxy Z Flip is unfolded, the 6.7-inch display has a ratio of 22 to 9, which makes the device taller than regular smartphones.
In terms of durability, the Galaxy Z Flip is rated better than the Razr. The Razr used a transparent polyimide (CPI) film made of plastic. In particular, before its release, smartphone experts pointed out that when the hinge screen was lifted with a nail, whenever a gap is opened or the phone is folded and unfolded, it made a “beep” sound. In the endurance test conducted by overseas IT media outlet CNET, the hinge of Razr was folded and unfolded more than 27,000 times, a problem occurred in the hinge part. The Galaxy Fold could be folded and unfolded more than 120,000 times.
