The Blackview Mega 3 has a footprint of 180.5 x 278.5 mm with a 7.4 mm thickness and a weight of 555 g, giving it a total volume of roughly 372 cm³. The tablet does not include a stylus, a detachable keyboard, or a backlit keyboard, and it offers no tilt sensitivity support. It also carries no water resistance rating, so it provides no certified protection against moisture or dust exposure.
The Blackview Mega 3 features a 12.1″ IPS LCD touchscreen with a resolution of 2560 x 1600 pixels and a pixel density of 249 ppi. The display does not include branded damage-resistant glass, an anti-reflection coating, or sapphire glass, and it does not support HDR10, HDR10+, or Dolby Vision. It is also not an e-paper panel.
The Blackview Mega 3 is powered by an octa-core processor with a configuration of 2 cores at 2.2 GHz and 6 cores at 2 GHz, built on a 6 nm semiconductor process with a TDP of 5W, and it uses big.LITTLE technology along with Heterogeneous Multi-Processing for workload distribution across its 8 threads. It is paired with 12GB of RAM running at 4266 MHz, offering a maximum memory bandwidth of 17.1 GB/s, and 256GB of internal storage that can be expanded via an external memory slot. Graphics are handled by an integrated Mali G57 GPU clocked at 1000 MHz, supporting DirectX 11, OpenGL ES 3.2, and OpenCL 2. The chipset also includes integrated LTE, ARM TrustZone security, and 64-bit support, and the device ships with Android 15.
The Blackview Mega 3 has a 50 MP rear camera with a CMOS sensor, an f/1.8 aperture, and a single LED flash, capable of recording video at 1080p and 30 fps. It supports touch autofocus, continuous autofocus during video recording, and a video light, while manual controls cover ISO, white balance, focus, and exposure, though manual shutter speed is not available. The rear camera does not include a back-illuminated sensor, optical image stabilization, or optical zoom, and it lacks slow-motion recording, timelapse, panorama, burst mode, HDR10 recording, Dolby Vision recording, and 3D capture. A 13 MP front camera is also present, though it does not have a dedicated LED flash, and the built-in HDR mode applies to standard shooting.
The Blackview Mega 3 includes stereo speakers and a built-in radio, but it does not have a 3.5 mm headphone jack. On the Bluetooth audio side, none of the advanced codecs are supported — aptX, aptX HD, aptX Low Latency, aptX Adaptive, aptX Lossless, and LDAC are all absent.
The Blackview Mega 3 is equipped with an 8800 mAh rechargeable battery that supports fast charging and includes a battery level indicator. The battery is not removable, and wireless charging is not supported.
The Blackview Mega 3 supports Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac) with download speeds of up to 650 MBits/s and upload speeds of up to 150 MBits/s, and it connects wirelessly via Bluetooth 5.0. It accepts one SIM card but has no cellular module and therefore no 5G support; GPS, NFC, HDMI output, Ethernet, and an infrared sensor are also absent. The tablet includes a USB Type-C port and supports Galileo positioning and device tracking, while an accelerometer is present but a gyroscope, compass, and barometer are not. On the software side, it offers a broad set of privacy and usability features, including location privacy options, camera and microphone access controls, app tracking blocking, clipboard warnings, and on-device machine learning, though Mail Privacy Protection, cross-site tracking blocking, and direct OS vendor updates are not available. Usability features include split-screen, Picture-in-Picture, full-page screenshots, a media picker, dark mode, dynamic and manual theme customization, an extra dim mode, notification controls, customizable notifications, app offloading, a child lock, multi-user support, widgets, sharing intents, voice commands, offline voice recognition, the ability to play games while downloading, and a battery health check, while Quick Start, Wi-Fi password sharing, focus modes, a fingerprint scanner, iris scanner, and 3D facial recognition are not included.
The Blackview Mega 3 uses DDR4 memory.
