The Blackview Tab 20 Wi-Fi measures 241.5 mm wide and 160 mm tall with a thickness of 9.4 mm, giving it a relatively slim profile for its class. It weighs 514 g, which places it in a moderate range for a 10.1-inch tablet. The device does not include a stylus, a detachable keyboard, or backlit keyboard support, and it offers no water resistance rating.
The Blackview Tab 20 Wi-Fi features a 10.1-inch IPS LCD touchscreen with a resolution of 1280 x 800 pixels and a pixel density of 149 ppi, delivering standard HD-level clarity for its size. The display runs at a 60 Hz refresh rate and does not include branded damage-resistant glass, an anti-reflection coating, or a sapphire glass panel. Advanced display standards such as HDR10, HDR10+, and Dolby Vision are not supported, and the screen is not of the e-paper type.
The Tab 20 Wi-Fi is powered by the Unisoc T310 chipset, built on a 12 nm process and configured with a quad-core CPU running at 1 x 2 GHz and 3 x 1.8 GHz using big.LITTLE technology across 4 threads, paired with 4 GB of RAM at 1333 MHz. Graphics are handled by an integrated PowerVR GE8300 GPU clocked at 800 MHz with a turbo ceiling of 800 MHz, supporting DirectX 10, OpenGL ES 3.2, and OpenCL 1.2. The tablet ships with 64 GB of eMMC 5.1 internal storage and accepts external memory cards of up to 2048 GB, while also supporting 64-bit processing, integrated LTE on the SoC, and runs Android 15 out of the box.
The Tab 20 Wi-Fi includes an 8 MP rear CMOS camera capable of recording video at 1080p and 30 fps, supported by a single LED flash and a video light for low-light shooting. Manual controls cover ISO, focus, exposure, and white balance, while touch autofocus and continuous autofocus during video recording are also available. HDR mode is built in, though optical zoom is absent and features such as slow-motion recording, timelapse, burst mode, panorama, optical image stabilization, HDR10 recording, and Dolby Vision recording are not supported. On the front, a 5 MP camera is present without a front-facing flash, rounding out a straightforward dual-camera setup suited to basic photo and video needs.
On the audio side, the Tab 20 Wi-Fi is equipped with stereo speakers and a 3.5 mm headphone jack, covering the essentials for both built-in listening and wired headphone use. It does not include a radio, and none of the Bluetooth audio codecs — aptX, aptX HD, aptX Low Latency, aptX Adaptive, aptX Lossless, or LDAC — are supported.
The Tab 20 Wi-Fi houses a 6000 mAh rechargeable battery with a built-in battery level indicator to keep track of remaining charge. The battery is non-removable and does not support fast charging or wireless charging.
The Tab 20 Wi-Fi connects wirelessly via Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) alongside Bluetooth 5.0, and uses a USB Type-C port running USB 2.0 for wired connectivity; HDMI output, NFC, Ethernet, and a cellular module are not included, meaning there is no 5G support either. For positioning, it features GPS with Galileo support and an accelerometer, while a gyroscope, compass, barometer, and infrared sensor are absent. On the software side, the tablet supports a broad set of Android features including dark mode, dynamic theming, theme customization, split-screen multitasking, Picture-in-Picture, widgets, full-page screenshots, a media picker, customizable notifications, notification controls, offline voice recognition, voice commands, and the ability to play games while downloading. Privacy options cover location controls, camera and microphone access management, clipboard warnings, and app tracking blocking, though cross-site tracking blocking, Mail Privacy Protection, and Wi-Fi password sharing are not available. Additional capabilities include on-device machine learning, multi-user support, a child lock, battery health check, app offloading, extra dim mode, device position tracking, and sharing intents, while Quick Start, focus modes, direct OS vendor updates, a fingerprint scanner, and 3D facial recognition are not supported.
The Tab 20 Wi-Fi uses DDR4 memory, representing the generation of RAM architecture employed by the device.
