Allview A4 Duo InDepth Review Specs and Pricing

Overview

The Allview A4 Duo, introduced in November 2013, represents a phone designed for basic communication needs. Though not a flagship device by today's standards, it offered a range of features that catered to budget-conscious consumers during its time. With dual SIM capabilities and a 3G connectivity, this phone was positioned for those needing a multi-network device at a reasonable price point.

Design and Build Quality

The Allview A4 Duo has a modest design with dimensions of 116.1 x 63.2 x 12 mm and a weight of 110.6 grams. The device's compact size made it highly portable and suitable for users looking for a phone that could easily fit in a pocket. Despite being mostly plastic, the build quality was sturdy enough for everyday use. The phone features a simple black design, reflecting the minimalism of early smartphone aesthetics.

Display

Featuring a 3.5-inch TFT display, the Allview A4 Duo offers a resolution of 320 x 480 pixels. This display size and resolution were typical for entry-level smartphones at the time. With a pixel density of approximately 165 ppi, the screen is adequate for basic tasks such as calling, messaging, and light web browsing but may not be suitable for high-resolution media consumption.

Performance

Under the hood, the Allview A4 Duo is powered by a dual-core 1.0 GHz Cortex-A7 processor, paired with a Mali-400 GPU. This combination delivers basic performance for simple tasks. The device runs on the Android 4.2 Jelly Bean operating system, which, at the time of its release, offered a stable and user-friendly experience. However, with only 512MB of RAM and 512MB of internal storage, the performance may lag when running more demanding applications or multitasking.

Camera

The Allview A4 Duo is equipped with a single 2 MP rear camera. Given the modest specifications, this camera is primarily suitable for capturing basic snapshots in well-lit conditions. Video recording capabilities are present but limited, making this phone less than ideal for users looking to capture high-quality multimedia content.

Battery Life

Powered by a removable Li-Ion 1200 mAh battery, the Allview A4 Duo provides up to 200 hours of standby time and up to 8 hours and 20 minutes of talk time. While the battery capacity is relatively low by modern standards, it suffices for basic daily usage, particularly if the device is used primarily for calls and texts.

Connectivity and Network

Supporting GSM and HSPA technology, the Allview A4 Duo provides 2G and 3G connectivity on bands GSM 900/1800 and HSDPA 900/2100, respectively. It includes standard connectivity features such as Wi-Fi 802.11 b/g/n, Bluetooth 4.0, and FM radio, enhanced by useful additions like Wi-Fi Direct and a microUSB 2.0 port.

Additional Features

This device incorporates basic sensors including an accelerometer and proximity sensor. While lacking some advanced features such as NFC and GPS, the Allview A4 Duo fulfills the requirements for a simple phone aimed at uncomplicated use.

Conclusion

The Allview A4 Duo is a testament to the era of budget smartphones, offering essential features that cater to users with straightforward communication needs. While it does not boast high-end specifications or features, its affordable price and functionality make it a suitable choice for those who prioritize basic utility without the frills of modern smartphones.
