Oppo A3s is a budget-focused OPPO phone from 2018, built around a large 6.2-inch IPS LCD, Snapdragon 450 hardware, dual rear cameras, and a 4230 mAh battery.
Its appeal is strongest for buyers comparing older affordable 4G phones that prioritize battery life, a dedicated microSD slot, and basic everyday usability over modern speed or software support.

Why Should You Buy the Oppo A3s?
The Oppo A3s makes the most sense as a low-cost secondary phone, backup handset, or simple daily device for calls, messaging, browsing, and light media use. Its strongest points are the large battery, dual SIM support, expandable storage, and familiar 3.5mm headphone jack.
Design and Build
The phone uses a glass front with Gorilla Glass 3, plus a plastic back and plastic frame. At 168 g and 8.2 mm thick, it stays reasonably manageable for a phone with a 6.2-inch screen and a large battery.
Display Quality
The 6.2-inch IPS LCD gives the Oppo A3s a roomy screen for videos, social apps, and reading. The HD+ resolution is modest by current standards, so sharpness is not its main strength, but it fits the phone’s entry-level positioning.
Performance and Storage
The Snapdragon 450 and Cortex-A53 CPU are designed for basic Android tasks rather than heavy gaming or demanding multitasking. The 3GB and 4GB RAM versions are the more practical choices, while the dedicated microSDXC slot helps offset limited internal storage.
Camera Experience
The rear camera setup combines a 13 MP main camera with a 2 MP depth sensor, mainly for casual daylight shots and portrait-style background separation. The 8 MP front camera is similarly basic, with 1080p video available on both sides.
Battery Life
Battery capacity is one of the A3s’ clearest advantages. The 4230 mAh cell is large for its class, and the efficient Snapdragon 450 plus HD+ display should help it last well in light to moderate use.
Software Experience
The phone runs Android 8.1 Oreo with ColorOS 5.1, which is now dated. That matters for app compatibility, security expectations, and interface polish compared with newer OPPO models.
Connectivity
Connectivity covers 4G LTE, Wi-Fi b/g/n, Bluetooth 4.2, GPS, FM radio, microUSB 2.0 with OTG, and dual Nano-SIM support. NFC is not included, so contactless payment support is not part of the package.
Who Should Buy It?
Consider the Oppo A3s if you need an inexpensive used or spare phone with dependable battery life, expandable storage, and basic 4G connectivity. Skip it if you want current Android software, sharper display quality, fast charging standards, or stronger performance.
Conclusion
The Oppo A3s is best viewed as a practical budget 4G phone with strong battery life and simple everyday features. It is worth considering only at a low price and mainly for light users.
