The Viper E supports GSM and HSPA technologies, providing decent connectivity options for users. For 2G, it covers GSM 900 / 1800 / 1900 MHz across both SIM slots, which are Micro-SIM and dual stand-by, while for 3G, it supports HSDPA 900 / 1900 / 2100 MHz. The device allows data speeds up to HSPA 21.1/5.76 Mbps, which sufficed for typical browsing and app usage in its service range.

Design and Build

With dimensions of 132 x 66 x 9.1 mm and a weight of 133.2 grams, the Viper E strikes a balance between compactness and ease of use. Its plastic body construction is typical for budget phones of that era, making it lightweight and practical for everyday handling. The phone is available in classic Black and White colors, providing simple yet elegant choices for consumers.

The device features a 4.5-inch IPS LCD screen with a resolution of 480 x 854 pixels, yielding a pixel density of approximately 218 ppi. Although not groundbreaking, this display was serviceable for general tasks, such as viewing photos or browsing the web. The screen-to-body ratio stands at around 64.1%, reflecting a decent use of the front surface.

Performance

Under the hood, the Allview V2 Viper E is powered by the Mediatek MT6580 chipset, a quad-core processor clocked at 1.3 GHz with Cortex-A7 cores.

The smartphone comes with 8GB of internal storage, which can be expanded via a microSDXC slot, offering users the flexibility to increase storage capacity as needed, a crucial feature for budget devices where on-board storage is limited.

Camera

The Viper E is equipped with a 5 MP autofocus rear camera, accompanied by features like LED flash, HDR, and panorama mode. It can record video at 720p@30fps, which, while modest by today’s standards, suited the needs of casual photography and video capturing at its time. For selfies and video calls, it utilizes a 2 MP front-facing camera.

Battery

Powered by a removable Li-Ion 1850 mAh battery, the Allview V2 Viper E provided adequate battery life, with standby time up to 185 hours and talk time up to 10 hours.
