The Oppo A3s is a discontinued budget smartphone with a 6.2-inch HD+ display, Snapdragon 450 chipset, dual rear cameras and a 4,230mAh battery. It remains relevant mainly to people checking the specifications of an existing handset or considering a low-cost used device. Its original appeal was straightforward: a roomy screen, practical battery capacity and a dedicated memory-card slot without a premium price tag.
Oppo A3s price and availability in Pakistan
The Oppo A3s is no longer a current retail model. PriceOye identifies it as discontinued and displays Rs. 18,999 as its last updated Pakistan price. That amount is a historical reference, not a verified live offer or a guaranteed selling price. A used, repaired or old-stock unit may be advertised for a different amount. Do not interpret the old retail figure as today's market quotation.
Before buying, ask a seller for the exact RAM and storage version, condition, accessories and return policy. A seller's claim of new stock should be supported by photographs of the actual unit, a clear warranty statement and a practical opportunity to inspect it. Prices and battery health vary substantially between individual second-hand phones.
Display and everyday design
The phone has a 6.2-inch IPS LCD with a 720 × 1520 resolution and a tall 19:9 aspect ratio. Its wide notch accommodates the front-facing camera and earpiece, while the relatively large screen makes reading messages and watching videos comfortable. The HD+ resolution is adequate for common tasks, but individual pixels are less refined than on newer Full HD displays.
At approximately 168 grams and 8.2mm thick, the A3s is a manageable size despite its broad body. Red and Dark Purple are the documented finishes. The glossy rear gives it a distinctive appearance, though older units can show scratches and fingerprint marks. Inspect the edges, corners and screen carefully, especially if a seller describes a handset as lightly used.
Snapdragon 450 performance and memory
Qualcomm's Snapdragon 450 uses an octa-core processor and Adreno 506 graphics. It was designed for basic smartphone use rather than demanding gaming. Phone calls, messaging, light browsing and video playback are sensible expectations for a well-maintained A3s; modern, heavier apps can load slowly or struggle with limited available memory.
The original configuration offered 2GB RAM and 16GB storage. Subsequent regional releases included 3GB with 32GB and 4GB with 64GB. Those versions did not necessarily have equal availability in Pakistan, so confirm the installed memory in the phone's settings rather than relying on a listing headline. A dedicated microSD slot helps store photos and files, but a card does not replace insufficient RAM or make the processor faster.
The handset originally shipped with Android 8.1 Oreo and ColorOS 5.1. That is an old software foundation, so buyers should not assume present-day Android security support or compatibility with every current banking, work or entertainment application. Check the specific applications you need before buying. Avoid devices with unknown firmware modifications or a locked account.
Rear cameras, selfies and video
The rear setup combines a 13MP main camera with a 2MP secondary depth camera. The second sensor supports portrait-style background blur; it is not a separate ultrawide or optical zoom lens. An LED flash assists in dark scenes, although low-light photography remains limited by the hardware. For casual daylight pictures, clean lenses and good lighting matter more than elaborate camera settings.
An 8MP front camera handles selfies and video conversations, with OPPO's AI Beauty feature appearing in the original launch material. Rear video recording is listed at up to 1080p at 30 frames per second. Do not expect modern stabilization, advanced night photography or the processing improvements available on recent camera phones.
Battery capacity and charging
A 4,230mAh battery was one of the A3s's main selling points at launch. Combined with the modest display resolution and efficient chipset, that capacity suited ordinary daily use. However, the figure describes the original battery specification, not the remaining capacity of a handset that has spent years in service. Older lithium-ion batteries can lose substantial endurance.
The device uses a Micro-USB connection rather than USB-C. Check whether the charging cable fits securely, whether the port works consistently and whether charging causes unusual heat. Charging power claims in online listings are inconsistent, so this page does not promise a particular fast-charging wattage. Ask about previous battery replacement work and whether genuine compatible parts were used.
Mobile networks and practical features
The Oppo A3s supports dual Nano-SIM use, 2G, 3G and 4G LTE, along with Wi-Fi, Bluetooth and GPS. It does not offer 5G connectivity. Network bands can differ between regional model codes; for a used import, confirm the phone works with your Pakistani operator before completing the purchase. Both voice calls and mobile data should be tested with a real SIM.
Other useful hardware includes a 3.5mm headphone socket, FM radio and USB On-The-Go support. The model does not have a rear fingerprint reader, so confirm the actual screen-lock options on the handset. It is better to verify an individual device's working functions than assume that every advertised feature is operational on an older unit.
PTA approval and checks before purchase
PTA compliance cannot be confirmed from the model name alone. A used Oppo A3s may be locally registered, imported, blocked or otherwise restricted. Dial *#06# to obtain the IMEI numbers, then check each one through PTA's official DIRBS verification channels or by sending it to 8484. Compare the reported device identity with the handset and packaging, if available.
Also test both SIM slots, microphones, loudspeaker, proximity sensor, Wi-Fi, charging socket, cameras and screen touch response. Inspect for display lines, ghost touches, water damage and signs of a loose battery cover. A phone that looks inexpensive can be poor value if it needs a screen, battery or motherboard repair soon after purchase.
Oppo A3s advantages and limitations
What still works in its favour
- The 6.2-inch screen offers useful space for calls, text and video.
- The 4,230mAh original battery capacity was generous for its class.
- Dual-SIM support and a dedicated microSD slot add flexibility.
- The 3.5mm headphone jack and basic 4G features remain practical.
Reasons to think twice
- Older software and limited memory can affect app compatibility.
- The Snapdragon 450 is not suitable for demanding current games.
- Micro-USB charging and basic cameras feel dated.
- Battery condition, PTA status and local stock must be verified unit by unit.
Who should consider this phone?
The Oppo A3s makes the most sense as a spare phone, a basic calling and messaging handset, or a familiar replacement for someone who already uses this model. It is a weaker choice for multitasking, banking applications with strict software requirements, prolonged gaming or a buyer seeking several years of security updates.
Compare the actual selling price of a clean, PTA-compliant A3s with newer entry-level models before deciding. A working battery, honest repair history and reliable local network operation matter more than a small difference in asking price. For most first-time buyers, a newer supported phone is a safer long-term purchase; for an existing owner, these specifications are a useful reference when judging whether maintenance or replacement makes sense.
