Performance
Under the hood, the K51S is powered by a Mediatek MT6765 Helio P35 chipset and an octa-core CPU, with four cores clocked at 2.3 GHz and four at 1.8 GHz. This, paired with the PowerVR GE8320 GPU and 3GB of RAM, produces decent performance for routine tasks such as browsing and social media. However, users may find it lacking when it comes to more demanding applications or gaming. It runs on Android 9.0 (Pie), which may seem outdated as newer Android versions are available, but it still manages most of the necessary applications and services efficiently.
