The Motorola Razr 40 is a foldable smartphone that harks back to the days of the classic clamshell design. This model folds along the short edge, allowing it to fit comfortably in a pocket while still providing a standard smartphone display when unfolded. The Razr 40 Ultra, its predecessor, boasted a large external display, ideal for quick message responses or selfies. However, the Razr 40 opts for a more retro approach, featuring a smaller external display that shows essential information.

Priced at US$755, the Razr 40 is one of the most affordable foldable smartphones on the market. The device's design is based on the robust hinge design of the Razr 40 Ultra, which becomes almost invisible when opened. Despite the hinge's apparent durability, the inner display remains susceptible to scratches, and a crease is visible where the display folds. This crease is only noticeable in backlight and doesn't significantly interfere with the device's operation.

The Razr 40's case is more robust due to the smaller external display, which is protected by Gorilla Glass Victus. This makes the device more resistant to pressure and torsion. However, it only has an IP52 certification, meaning it's not fully protected against dust and water splashes.

The Razr 40 shares the same weight and dimensions as the Razr 40 Ultra, with the exception of being slightly thicker. The device has a high-quality appearance, thanks to the imitation leather covering most of its front and back. It's available in Sage Green, Vanilla Cream, and Summer Lilac, with a metal frame that matches the chosen color.

The Razr 40 comes with 8 GB of RAM and 256 GB of storage, but it uses slower flash memory than the Ultra model. It lacks a microSD slot and a second SIM slot, but it does support virtual SIM cards. The device runs on Android 13 and comes with a few apps for device-specific functions, but otherwise, it doesn't deviate from stock Android.

The Razr 40 supports WiFi 6E, ensuring stable data transfer. It also supports a wide range of mobile networks, making it suitable for global use. The device's tracking module can access all major satellite networks, providing quick and accurate location data.

The Razr 40's main camera is a 64-megapixel sensor from OmniVision, which offers slightly lower light sensitivity but features an optical image stabilizer. The photos it produces are colorful and well-lit, although they lack the sharpness and detail of high-end smartphone cameras. The device can record videos in 4K at a maximum of 30 fps.

The Razr 40's OLED main screen features an extended Full HD resolution and can display colors very accurately. The device's graphics card is sufficient for 1080p gaming, provided you're satisfied with 30 fps. The Razr 40 uses older UFS 2.2 flash, which means data transfers can take longer and loading times can be extended.

The Razr 40's battery is more powerful than that of the Razr 40 Ultra or the Samsung Galaxy Z Flip4, resulting in good runtimes for a foldable device. The smartphone can be fully charged in less than 1:30 hours using a 30-watt charger.

In conclusion, the Motorola Razr 40 is a stylish and economical foldable smartphone that offers decent performance and long battery life. It's not without its flaws, such as the lack of a USB 2.0 port and average camera quality. However, for those looking for a foldable smartphone at a lower price point, the Razr 40 is a compelling option.
