Design & build: What to expect
The A02s comes with a typical design for a designated smartphone: plastic with a stripe matte finish and a rectangular camera module on the back. The A02s smartphone is slightly thick at 9.1 mm. It is also quite heavy at around 196 grams. This is because the A02s smartphone comes with a 5000 mAh battery. When you hold the A02s, you can feel that it is designed to be durable rather than stylish. The designers of the A02s decided to use materials that can protect the phone from drops and scratches rather than making it look shiny and pretty. The side rails and the back of the A02s smartphone are designed to be scratch-resistant when you use it normally. The phone is quite heavy, but this is because it comes with a 5000 mAh battery.
Display & multimedia
The 6.5″ HD+ PLS/TFT screen is quite good for viewing apps and videos. It is large and easy to view.. The 6.5″ HD+ PLS/TFT screen does not have as many pixels as other screens that are a little better. The colors on the 6.5″ HD+ PLS/TFT screen are okay if you are just looking around. It is not very bright if you are outside. If you are outside in the sunlight, it is difficult to see what you are looking at, on the 6.5″ HD+ PLS/TFT screen.. If you are not directly in front of the 6.5″ HD+ PLS/TFT screen, it is a little difficult to see too. Audio is what you’d expect from this category: a single bottom-firing speaker with sufficient richness for hands-free video playback in a quiet room, and a preserved 3.5mm headphone jack for audio output.
performance & benchmarks
What the Snapdragon 450 means
The Snapdragon 450 is a previous-generation, power-efficient entry-level processor with a 14nm process. It is designed for low power consumption, not for high CPU/GPU performance. You can expect smooth performance in messaging apps, social media, streaming, and basic multitasking. More demanding tasks such as Sustained Gaming, heavy photo editing, or resource-intensive web browsing would initiate background process halts, slow app launches, and potential thermal throttling
Representative benchmarks
Typical benchmarks for devices in this performance category would rate them in the low-end category for single-core performance, modest to limited multi-core performance, and GPU performance that is sufficient for low-poly 3D gaming. Specific AnTuTu and Geekbench scores will depend on the device being tested. For editorial content, ranges should be provided for numerical data to prevent bias from sampling.
UX tips to keep it snappy
- Use Settings → Device care → Optimize to periodically free RAM.
- Limit background procedure and remove seldom-used apps.
- Avoid large live wallpapers or multiple live widgets.
- Enable Developer options → Window animation scale = 0.5× or off to reduce perceived lag on low-RAM SKUs.
Battery life & charging
Battery size & endurance
The highlight of the phone is the 5000 mAh battery. In real-world usage patterns, including calls, messaging, streaming, and light gaming, the battery life is expected to last more than a day, often extending to two days on low usage patterns. In this category, web browsing tests in synthetic specification may last 16-20+ hours.
Charging performance
The phone comes with support for 15W charging. Although it is “fast” charging in the budget segment, 15W is very slow compared to the latest flagships that come with 25W-100W charging. Charging times from low battery levels take around 2-3 hours with a good 15W charger.
Long‑term battery care
For longevity, it is recommended that the battery does not go through extreme charge cycles (0-100%) on a regular basis. Many battery health-conscious users charge their batteries between 20-80% on a daily basis as a measure to preserve battery health. It is recommended that a branded charger be used and not cheap chargers that could damage the battery..
Cameras: strengths & limits
Hardware summary
- Rear: 13 MP main (wide, AF) + 2 MP macro + 2 MP depth.
- Front: 5 MP selfie.
Daylight & casual use
Daylight camera photos are surprisingly usable for the price: good color gamut and dynamic range in equal lighting. The 13 MP camera is best used in bright outdoor lighting conditions where autofocus is accurate and detail is maintained.
Low light and video
Low-light imaging is a known weakness, with noise rising, dynamic range contracting, and the camera reducing shutter speeds, which will result in motion blur when shot handheld. Video is capped at 1080p@30 fps, with no advanced stabilization, and low-light handheld video will exhibit visible shake.
Practical camera tips
- Use HDR mode in high-contrast scenes to preserve highlights/shadows.
- For macro shots, ensure good lighting or use a desk lamp to keep shutter speeds reasonable.
- For portraits, use the default 13 MP main camera with depth-assisted background blur rather than the 2 MP macro, which is low resolution.
- Secure the phone with both hands or a small tripod for low-light scenes.
Software & updates
The A02s supports Android 10 and One UI Core. The updates that the manufacturer puts out are different depending on the version of the A02s and where you live in the world. Samsung’s lower-cost phones, such as the A02s, receive updates for the Android operating system but not very often security updates compared to the higher-cost mid-range and flagship phones. If you are interested in knowing what updates are available for your A02s, you can check out Samsung’s support pages for your version of the A02s to see what updates it has received.
Tips for users: keep the device updated through Settings → Software update, download Samsung Members for troubleshooting, and check carrier websites for variant-specific software.
Cellular bands & variants
There are several SKUs: SM-A025F, SM-A025G, SM-A025M, and others. It is essential to check the SKU before buying, especially if you are a foreign buyer and need a particular LTE band. Include a small SKU table on the country-specific purchase pages.

Comparison: A02s vs similar budget rivals
A compact comparison helps readers quickly choose:
| Model | Display | SoC | RAM/Storage | Battery | Camera | Typical advantage |
| sansung Galaxy A02s | 6.5″ HD+ | Snapdragon 450 | 2–4GB / 32–64GB | 5000 mAh | 13/2/2 MP | Battery & brand trust |
| Redmi (equiv) | 6.5″ FHD* | Varied Helio/Snapdragon | 3–4GB | 5000 mAh | 48 MP options | Stronger SoCs in many SKUs |
| Realme (equiv) | 6.5″ FHD* | Faster chips in some SKUs | 3–4GB | 5000 mAh+ | 13–48MP | Better performance/charging |
*FHD depends on the specific model.
Short take: Xiaomi/Realme rivals often trade on superior raw specs for slightly lower price points; Samsung’s A02s trades some performance for consistent software polish and broad retailer support.
Troubleshooting & common fixes
Slow performance: Clear app cache, uninstall unused apps, disable animations (Developer options), restart device.
Battery drain: Analyze battery usage in Settings → Battery; restrict background apps, reduce display brightness, and use battery saver.
Wi‑Fi issues: Toggle Wi‑Fi, forget and re-add network, restart router & phone; test other devices to isolate.
Camera app crashing: Clear Camera app cache & data, reboot, or update firmware.
Factory reset: Settings → General management → Reset → Factory data reset. Use Safe Mode (hold power, long-press Power off → Safe mode) to test third-party app conflicts.
Always backup important data before factory resets. For warranty repairs and firmware downloads, direct users to Samsung support pages and Samsung Members diagnostics.
