Under the hood, the Vivo Y21 is powered by the MediaTek MT6765 Helio P35 chipset, coupled with an octa-core CPU. This combination, alongside the PowerVR GE8320 GPU, caters reasonably well to basic and moderate tasks. The device runs on Android 11 with the Funtouch 11.1 interface, offering a smooth user experience with a variety of customization options. Memory-wise, the phone provides two options: 64GB or 128GB of internal storage, both paired with 4GB of RAM, and supports microSDXC expansion, ensuring ample space for apps and media.
