Umidigi G100

The Umidigi G100 has a straightforward design with a thickness of 8.1 mm, keeping the handset relatively slim for a device in its category. It does not feature a rugged build or a folding form factor, and it carries no water resistance rating, meaning it offers no certified protection against moisture or dust exposure.

The Umidigi G100 uses an IPS LCD touchscreen measuring 6.9″ with a resolution of 1080 x 2460 pixels and a pixel density of 389 ppi, delivering a reasonably sharp visual experience across its large panel. The display supports a 120Hz refresh rate, which allows for smoother on-screen motion during everyday use. However, it lacks branded damage-resistant glass, and there is no support for HDR10, HDR10+, or Dolby Vision, nor does it offer an Always-On Display mode or a secondary screen.

The Umidigi G100 is driven by the Unisoc T615 chipset, built on a 12 nm process and configured as an octa-core processor using big.LITTLE technology, with two cores clocked at 1.8 GHz and six at 1.6 GHz across 8 threads, carrying a TDP of 10W. It comes with 4GB of LPDDR4 RAM running at 1866 MHz and 128GB of eMMC 5.1 internal storage, while external storage can be expanded by up to 256GB, and the maximum supported memory amount reaches 12GB. Graphics are handled by the integrated Mali G57 GPU, clocked at 850 MHz with 2 execution units and 64 shading units, supporting OpenGL 3.2, OpenGL ES 3.2, and OpenCL 2. The SoC includes integrated LTE, ARM TrustZone security, and a 1 MB L3 cache, and the platform supports both 64-bit processing and multithreading. In Geekbench 6, the device scores 437 in single-core and 1461 in multi-core testing, with Geekbench 5 results of 357 and 1350 respectively.

The Umidigi G100 features a multi-lens rear camera system led by a 50MP main CMOS sensor, accompanied by two additional 2MP lenses, and supports phase-detection autofocus for stills, touch autofocus, continuous autofocus during video recording, and manual controls for exposure, ISO, focus, and white balance. A flash is present, though it is a single-tone unit — dual-tone and RGB LED options are absent — and optical image stabilization is not available, nor is there any optical zoom. Video recording on the main camera tops out at 1080p at 30fps, with slow-motion recording supported but no HDR10 or Dolby Vision recording. Additional shooting modes include HDR, burst mode, and in-camera panoramas, while 360° panorama capture and RAW shooting are not supported. On the front, a single 16MP camera handles selfies without a dedicated flash or a secondary lens, and it is positioned in the standard location rather than under the display.

The Umidigi G100 runs Android 14 and comes with a solid set of privacy controls, including clipboard warnings, location privacy options, and camera and microphone access management, though Mail Privacy Protection and cross-site tracking blocking are absent. On the customization side, it supports dark mode, dynamic theming, theme customization, widgets, and customizable notifications, while focus modes and app offloading are not available. The OS includes practical productivity features such as split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, sharing intents, and the ability to play games while they download. On-device machine learning is supported alongside offline voice recognition and voice commands, and the device can track its own position and operate as a multi-user system with a child lock option. Wi-Fi password sharing and Quick Start are not supported, and the device does not receive direct OS updates from the vendor.

The Umidigi G100 is equipped with a 6000 mAh rechargeable battery that supports 20W wired fast charging, allowing for reasonably quick top-ups when connected to a compatible charger. A battery level indicator is included, keeping users informed of remaining charge at a glance. Wireless charging is not available, and the battery is non-removable.

The Umidigi G100 includes a built-in radio, offering access to FM broadcasts without relying on a data connection. On the wireless audio side, the device does not support any high-quality Bluetooth audio codecs, with aptX, aptX HD, aptX Adaptive, aptX Lossless, and LDAC all absent from its feature set.

The Umidigi G100 supports dual SIM cards and connects via Wi-Fi, Bluetooth 5, and a cellular module, though it is limited to 4G with maximum download and upload speeds of 300 Mbits/s and 150 Mbits/s respectively — 5G is not supported. It uses a USB Type-C port running on USB 2.0 and includes an external memory slot for expandable storage. NFC is absent, as are HDMI output, DLNA certification, and ANT+ support. For navigation, the device features GPS, Galileo, a compass, a gyroscope, and an accelerometer, while a barometer, heart rate monitor, infrared sensor, and both motion and optical tracking are not present. Security is handled by a fingerprint scanner, with no iris scanner, 3D facial recognition, or satellite emergency SOS available. A stylus is not included, and crash detection is not supported.

The Umidigi G100 includes a video light, which can be used to illuminate scenes during video recording. The display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
