Performance and Software
Under the hood, the Vivo X21 UD is powered by the Qualcomm Snapdragon 660 chipset, which, despite being mid-range, is capable of delivering solid performance for everyday tasks and moderate gaming. The octa-core CPU configuration, which includes Kryo 260 Gold and Silver cores, ensures a balance between power and efficiency. Paired with the Adreno 512 GPU, this setup handles most graphical tasks admirably. The phone originally shipped with Android 8.1 (Oreo) layered with Vivo's Funtouch OS 4, which offers a unique user experience with added customization options.
