Performance
Under the hood, the Yezz Billy 4 is powered by a Qualcomm MSM8212 Snapdragon 200 chipset with a quad-core 1.2 GHz Cortex-A7 CPU and Adreno 302 GPU. Although these specifications highlight modest performance capabilities by today’s standards, they were acceptable for running Windows Phone 8.1 and handling basic applications smoothly in its time. The phone is equipped with 512MB of RAM and 4GB of internal storage, expandable via a dedicated microSDXC slot, which suffices for essential applications and data storage but would be limiting for heavy usage or data-intensive applications.
