Performance
Under the hood, the vivo Y51 is powered by Qualcomm's Snapdragon 410 chipset, featuring a quad-core 1.2 GHz Cortex-A53 CPU. Paired with 2GB of RAM, it provides a serviceable performance for general tasks. The phone runs on Android 5.0.2 Lollipop with Vivo’s Funtouch 2.5 UI, offering a user-friendly interface yet lacking more contemporary Android functionalities due to its older software version. The Adreno 306 GPU delivers basic graphics performance, suitable for casual games but not intensive gaming or graphic-heavy applications.
