Infinix Zero 40 4G

The Infinix Zero 40 4G has a non-folding, non-rugged design measuring 164.3mm tall, 74.6mm wide, and just 7.7mm thick, with a total volume of approximately 94.38cm³ and a weight of 180g. It carries an IP54 ingress protection rating, making it resistant to dust and water splashes in everyday situations.

The Infinix Zero 40 4G features a 6.78″ OLED/AMOLED touchscreen with a resolution of 1080 x 2436 px and a pixel density of 393 ppi, delivering reasonably sharp visuals across its single display — there is no secondary screen. It runs at a 120Hz refresh rate and supports Always-On Display, while the panel is protected by Gorilla Glass 5. HDR10, HDR10+, and Dolby Vision are not supported on this display.

The Infinix Zero 40 4G is powered by the MediaTek Helio G100 chipset, built on a 6nm process with an octa-core CPU running at 2 x 2.2 GHz and 6 x 2 GHz using big.LITTLE architecture with HMP support, and comes paired with 8GB of DDR4 RAM clocked at 4266 MHz and 512GB of internal storage, with a maximum supported memory amount of 12GB. Graphics are handled by the integrated Mali G57 GPU running at 1000 MHz, supporting DirectX 11, OpenGL ES 3.2, and OpenCL 2, with a maximum memory bandwidth of 17.1 GB/s. The SoC includes integrated LTE, TrustZone security, 64-bit support, and operates within a 5W thermal design power envelope across its 8 CPU threads.

The Infinix Zero 40 4G features a triple rear camera system with a 108MP main sensor at f/1.8, a 50MP lens at f/2, and a 2MP lens at f/2.4, all using a CMOS sensor without back-illumination, and supported by optical image stabilization, phase-detection autofocus, touch autofocus, and continuous autofocus during video recording, though laser autofocus is absent and there is no optical zoom. Manual controls cover exposure, ISO, focus, and white balance, while manual shutter speed is not available; additional shooting modes include HDR, burst, panorama, slow-motion video, and timelapse. Video recording tops out at 1440p at 30fps, with two rear flash LEDs, though HDR10 and Dolby Vision recording are not supported, nor is 3D capture. On the front, a single 50MP camera sits at f/2.5 — not under the display — without a front flash or a secondary front lens, and the front camera does not support HDR10 or Dolby Vision recording either.

The Infinix Zero 40 4G runs Android 14 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, camera and microphone access management, and app tracking prevention, though Mail Privacy Protection and cross-site tracking blocking are not available. The OS supports theme customization, dynamic theming, dark mode, and an extra dim mode, while focus modes and app offloading are absent. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, a media picker, customizable notifications, sharing intents, widgets, Live Text, and the ability to play games while they download, though Wi-Fi password sharing and Quick Start are not supported. On-device machine learning, offline voice recognition, voice commands, phone tracking, battery health check, child lock, and multi-user support are all present, but the device does not receive direct OS updates from the vendor and cannot be used as a PC.

The Infinix Zero 40 4G is equipped with a 5000 mAh rechargeable, non-removable battery that supports 45W fast charging, and a charger is included in the box. A battery level indicator is present for monitoring charge status, though wireless charging is not supported.

The Infinix Zero 40 4G includes stereo speakers and a built-in radio, but does not have a 3.5mm headphone jack. On the wireless audio side, none of the high-quality Bluetooth codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC — are supported.

The Infinix Zero 40 4G supports 4G cellular connectivity — there is no 5G — and accommodates two SIM cards with download speeds of up to 650 Mbit/s and upload speeds of up to 150 Mbit/s. Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) are supported, alongside NFC, USB Type-C (USB 2.0), and an infrared sensor, though HDMI output, external memory expansion, and DLNA certification are absent. For location and motion sensing, the device includes GPS with Galileo support, a compass, gyroscope, and accelerometer, while a barometer, heart rate monitor, and both motion and optical tracking are not present. Biometric authentication is handled by a fingerprint scanner, without 3D facial recognition or an iris scanner, and no stylus is included. Emergency SOS via satellite, crash detection, ANT+, and a built-in projector are also not featured.

The Infinix Zero 40 4G features a curved display and a video light, while it does not use sapphire glass or include an e-paper display.
