Performance
Running on Android 11 with Funtouch OS 10.5, the vivo Y31s is powered by the Qualcomm SM4350 Snapdragon 480 5G chipset, a surprising yet commendable inclusion for a budget device. The octa-core CPU setup and Adreno 619 GPU ensure that the phone handles everyday tasks and moderate gaming without noticeable hiccups. Users can choose between different memory configurations, including 64GB with 4GB of RAM and 128GB with either 4GB or 6GB of RAM, all based on UFS 2.1 technology which provides fast read and write speeds. However, the absence of a microSD card slot might be a limiting factor for those needing additional storage.
