Cubot A40

The Cubot A40 has a tall form factor, measuring 172.3 mm in height, 78.1 mm in width, and 8.8 mm in thickness, with an overall volume of 118.42 cm³. It is a conventional candy-bar design with no folding mechanism and no rugged certification. The device also carries no water resistance rating, meaning it offers no official protection against moisture or dust exposure.

The Cubot A40 features a 6.88-inch IPS LCD touchscreen with a resolution of 720 x 1640 px and a pixel density of 260 ppi. It supports a 120Hz refresh rate, which contributes to smoother on-screen motion during everyday interactions. The display does not include branded damage-resistant glass, and it lacks support for HDR10, HDR10+, Dolby Vision, and Always-On Display functionality. There is no secondary screen present on the device.

The Cubot A40 is built around the Unisoc T606 chipset, fabricated on a 12 nm process with an 8-thread CPU running at 2 x 1.6 GHz and 6 x 1.6 GHz, supported by big.LITTLE architecture and Heterogeneous Multi-Processing (HMP). It is paired with 8 GB of DDR4 RAM at 1600 MHz, up to 14 GB maximum memory support, and 256 GB of eMMC 5.1 internal storage. The Mali G57 MP1 GPU runs at 650 MHz with 64 shading units and one execution unit, supporting DirectX 12, OpenGL ES 3.2, and OpenCL 2.0, with a maximum memory bandwidth of 12.8 GB/s. Cache configuration includes 128 KB of L1, 2 MB of L2, and 1 MB of L3 cache, while the chipset carries a TDP of 10W and integrates LTE connectivity. Benchmark results show a Geekbench 6 multi-core score of 1391 and single-core score of 371, a Geekbench 5 multi-core score of 1175 and single-core score of 313, and a PassMark score of 2663 with a single-core result of 988. The platform also includes TrustZone security support and integrated graphics.

The Cubot A40 features a dual-lens rear camera system with a 48 MP main sensor and a 2 MP secondary sensor, both using a CMOS configuration without a back-illuminated sensor. Autofocus options include phase-detection and touch autofocus for photos, as well as continuous autofocus during video recording, though laser autofocus is not present. The rear camera supports a broad set of manual controls — including manual ISO, manual focus, manual exposure, and manual white balance — along with HDR mode, burst shooting, panorama, timelapse, and slow-motion video recording. A single LED flash is available, with no dual-tone or RGB flash. Optical zoom is not supported, and the camera does not shoot in RAW format, nor does it offer manual shutter speed control, 360-degree panorama, HDR10 or Dolby Vision recording, or 3D capture. On the front, a 16 MP single-lens camera is included without a front-facing flash or an under-display placement.

The Cubot A40 runs Android 15 and includes a broad range of privacy and usability features. On the privacy side, it offers clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though Mail Privacy Protection and cross-site tracking blocking are not available. The interface supports dark mode, dynamic theming, theme customization, widgets, customizable notifications, notification permission controls, and an extra dim mode for low-light comfort. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, Live Text, a media picker, app offloading, sharing intents, and the ability to play games while they are downloading. On-device machine learning is supported alongside offline voice recognition and voice commands, and the system functions as a multi-user platform with phone tracking and child lock capabilities. Battery health check is also included. The device does not support Wi-Fi password sharing, focus modes, Quick Start, or direct OS updates from the vendor, and it cannot be used as a PC.

The Cubot A40 is equipped with a 5100 mAh rechargeable battery that is non-removable and includes a battery level indicator. The device does not support fast charging, wireless charging, or reverse wireless charging.

The Cubot A40 includes stereo speakers but omits a 3.5 mm headphone jack, meaning wired audio requires an adapter or Bluetooth connection. No radio is present, and Bluetooth audio codec support is limited, with no aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC available.

The Cubot A40 supports Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), Bluetooth 5.0, NFC, and USB Type-C, and accommodates two SIM cards alongside an external memory slot for expandable storage. Cellular connectivity is present with download speeds of up to 300 Mbit/s and upload speeds of up to 100 Mbit/s, though 5G is not supported. Location services include GPS and Galileo support, and an accelerometer is on board, while a compass, gyroscope, barometer, infrared sensor, heart rate monitor, and ANT+ are all absent. Security options are limited as there is no fingerprint scanner, 3D facial recognition, or iris scanner included. Additional features such as HDMI output, DLNA certification, motion tracking, optical tracking, crash detection, emergency SOS via satellite, and a built-in projector are likewise not available, and no stylus is included with the device.

The Cubot A40 includes a video light for illumination during video recording. The display is flat rather than curved, and the device uses neither sapphire glass nor an e-paper panel.
