Short Review
- The Yezz Billy 4 features a compact design with dimensions of 122.5 x 64.4 x 9.9 mm and a lightweight build at 109 grams, available in multiple colors.
- Its 4.0-inch TFT display offers a resolution of 480 x 800 pixels, resulting in a pixel density of approximately 233 ppi, suitable for basic tasks.
- Performance is powered by a Qualcomm MSM8212 Snapdragon 200 chipset, a quad-core 1.2 GHz Cortex-A7 CPU, and 4GB of RAM, providing adequate functionality for everyday use.
- The 8 MP rear camera captures decent images, but lacks optical image stabilization, while video recording is limited to 720p at 30fps.
- A 1.3 MP front camera is available for selfies, though it is basic in capability.
- The 1300 mAh battery offers limited endurance and does not support fast or wireless charging.
- Running on Microsoft Windows Phone 8.1, the software experience may feel dated compared to modern standards.
- Connectivity options include dual-band Wi-Fi and Bluetooth 4.0, but it lacks 5G support and NFC.
- The device does not feature stereo speakers, but includes a headphone jack for audio output.
- Overall, the Yezz Billy 4 is a basic smartphone with essential features suitable for light usage.
