Allview V4 Viper

The Allview V4 Viper is suited to people looking for a straightforward phone for calls, messages, and basic tasks, provided they accept its 2,700mAh battery as the main limitation. Its 2GB of RAM and 16GB of storage leave limited room for apps and files, although storage can be expanded.

The 5.7-inch IPS LCD display has a resolution of 720 × 1520 pixels and a density of 295 ppi. That gives messages and web pages a defined viewing area, with the resolution setting the level of detail. A quad-core MediaTek Helio A22 processor and PowerVR GE8320 GPU handle the phone’s computing and graphics hardware. It runs Android 9.

The 8MP rear camera includes an LED flash and records video at 1080p and 30 fps; the front camera is 5MP. Connectivity includes Dual Nano-SIM, Wi-Fi 802.11 b/g/n, Bluetooth 4.1, GPS, and GLONASS. A 3.5mm audio jack supports wired headphones, and FM radio offers another way to listen to audio. The phone weighs 138g, making it light to carry.

The V4 Viper is best considered for basic use, particularly when two SIM cards, expandable storage, a headphone jack, or FM radio are useful. Its small memory allocation calls for modest expectations about installed apps and stored files, while the 2,700mAh battery remains the central compromise. It is a simple option for those priorities, rather than a fit for buyers who need generous built-in capacity.
