The Oppo A5s uses an octa-core (4×2.3 GHz Cortex-A53 & 4×1.8 GHz Cortex-A53) MediaTek Helio P35 SoC, the same processor that powers the Vivo Y17 and the Honor A8 Pro.
While the processor is not the fastest one you’ll find in phones in the 10k segment, it can handle everyday tasks very well. You can multitask with ease. However, you might notice a slight lag when launching specific apps like Facebook and Instagram and also while navigating between apps. As for gaming, the Oppo A5s can run small and lightweight games pretty smoothly.
On the contrary, when it comes to heavyweight games like PUBG, the phone is not optimized for it. If you love binge-watching, the Oppo A5s is a good phone that delivers a pleasant experience. Both the Face Unlock and the Fingerprint Sensor are responsive and work well.
The phone features Oppo’s custom OS – ColorOS 5.2 based on Android Oreo. Dated as it may be, the UI seems fluid for the most part, and it comes with a lot of useful shortcuts and gestures. You also get the Game Space, Kid Space, Smart Sidebar, Multi-Screen, and a lot more.
