The device offers HSPA support with speeds up to 21.1/5.76 Mbps, providing decent internet access for everyday browsing and social media usage. Despite lacking 4G connectivity, the device can handle standard cellular and data requirements efficiently.

Design and Build

Released in October 2019, the BLU J4 features a compact body with dimensions of 151 x 72.3 x 10 mm and a weight of 158 grams. The design incorporates a dual SIM (Nano-SIM, dual stand-by) configuration allowing users to manage separate personal and professional numbers conveniently. The phone is available in three color variants: Blue, Black, and Brown, giving users some personalization options.

Display

The device sports a 5.5-inch IPS LCD display with a resolution of 720 x 1440 pixels and an 18:9 aspect ratio, providing adequate visual quality for its price range. The screen ensures around 71.5% screen-to-body ratio and delivers a pixel density of approximately 293 ppi. This setup offers a decent viewing experience for watching videos and playing casual games, though high-definition content may not appear as sharp due to limited resolution.

Performance and Platform

Running on Android 8.1 Oreo (Go edition), the BLU J4 is tailored for budget-friendly performance. The Go edition of Android ensures smoother experience on devices with lower RAM, which in this case is 1GB. The phone is powered by a Quad-core 1.3 GHz Cortex-A7 processor accompanied by a Mali-400 GPU, making it suitable for basic tasks and applications. While not designed for heavy multitasking or high-performance gaming, it handles everyday operations with relative ease.

Memory and Storage

With 32GB of internal storage, the device offers sufficient space for apps, photos, and other media. For those requiring additional storage, a microSDXC slot is available for memory expansion. This feature allows users to potentially expand storage up to several gigabytes depending on the capacity of the microSD card used, providing flexibility for managing larger collections of files or applications.

Camera

The BLU J4 features an 8 MP autofocus rear camera, complete with LED flash, capable of shooting 720p videos at 30 frames per second. For selfie enthusiasts, an 8 MP front-facing camera is available, also capable of capturing 720p video. While the camera system may not cater to advanced photographic needs, it is more than adequate for everyday photography and video calls, particularly given the device's budget category.

Audio and Comms

Communication options include Wi-Fi 802.11 b/g/n with Wi-Fi Direct support, Bluetooth 4.1 with A2DP and LE, and GPS for navigation. Additionally, the device includes an FM radio, offering entertainment and news on the go, while connectivity is further facilitated through a microUSB 2.0 port.

Battery and Sensors

Powering the BLU J4 is a Li-Po 2200 mAh removable battery, a feature that allows for replacement if needed, potentially extending the device's lifespan. Although not particularly high-capacity, this battery is sufficient for a day of moderate use given the device's efficient hardware and software optimization. The inclusion of an accelerometer sensor allows the phone to adequately manage screen orientation and certain motion-based applications.
