Samsung A40 Vs A10 Is It Worth Upgrading Or Sticking With The A10

When Samsung released both the Galaxy A10 and Galaxy A40 within months of each other in 2019, many users were left wondering: is there enough difference between these two budget phones to justify an upgrade? At first glance, they look similar—compact, affordable, and aimed at entry-level buyers. But beneath the surface, key differences in display, processor, camera, and software support could influence your decision. Whether you're currently using the A10 or considering one secondhand, understanding how the A40 improves upon it can help determine if stepping up is truly worthwhile.

Design and Build Quality

Both phones feature plastic bodies and minimal bezels, but the design language differs slightly. The Galaxy A10 has a more traditional front with a wide forehead and chin, while the A40 adopts a sleeker Infinity-U display with a smaller notch for the front camera. This gives the A40 a more modern aesthetic and slightly better screen-to-body ratio (85% vs 80%).

The A40 also feels more compact despite having a marginally larger screen. It measures 144.4 x 69.4 x 7.9 mm compared to the A10’s 155.6 x 75.6 x 7.9 mm. The smaller footprint makes the A40 easier to handle with one hand, especially for users who prioritize portability.

Display Comparison: Clarity and Usability

The most noticeable difference lies in the display. The A10 uses a 6.2-inch HD+ (720 x 1520) PLS TFT panel, which delivers acceptable brightness but lacks sharpness and color depth. In contrast, the A40 steps up to a 5.9-inch Super AMOLED Full HD+ (1080 x 2280) screen. This isn’t just a spec bump—it translates into real-world improvements.

Super AMOLED technology provides deeper blacks, richer colors, and better contrast. Even though the A40’s screen is slightly smaller, its higher resolution means text appears crisper and images are more vivid. For media consumption, reading, or browsing social media, the visual experience on the A40 is significantly superior.

Performance and Hardware: Is the Upgrade Noticeable?

Under the hood, both phones rely on entry-level chipsets. The A10 uses the Exynos 7884B (14nm), paired with 2GB of RAM and 32GB storage. The A40 runs on the same chipset but comes with 4GB of RAM and 64GB of internal storage—double the memory and storage of the base A10 model.

This difference impacts multitasking and app responsiveness. On the A10, switching between apps often requires reloading, and background processes are quickly terminated. The A40 handles multiple open apps more smoothly, reducing frustration during daily use.

Benchmarks reflect this gap: the A40 scores around 950 on AnTuTu v7, while the A10 lingers near 750. While neither will run high-end games smoothly, the A40 manages casual gaming and streaming with fewer stutters.

Storage Expandability

Both phones support microSD cards up to 512GB via a dedicated slot. However, the A40’s larger base storage reduces the urgency to expand immediately, giving users more breathing room for photos, music, and apps.

Camera Capabilities: Photo Quality Differences

On paper, both models feature a single 13MP rear camera and a 5MP front shooter. But hardware alone doesn’t tell the full story—software optimization plays a crucial role.

The A40 benefits from improved image processing thanks to better tuning and additional features like Live Focus (portrait mode with bokeh effect). While the A10 captures usable daylight photos, its images often lack detail and dynamic range. Low-light performance is poor on both, but the A40 produces slightly less noisy shots with better edge detection.

The front camera sees a modest improvement too. Selfies on the A40 appear sharper, with more natural skin tones and better background separation in portrait mode.

Battery Life and Charging

The A10 holds a slight edge in battery capacity with a 3400 mAh cell versus the A40’s 3100 mAh. In practice, this results in about 1–1.5 hours more screen-on time under moderate use. However, the A40’s more efficient Super AMOLED display helps offset some of that deficit.

During typical usage—social media, messaging, light browsing—the A10 lasts closer to a full day and a half, while the A40 may require charging by late evening. Neither supports fast charging beyond 15W, so recharge times are similar (~2 hours).

Software and Longevity

This is where the A40 pulls ahead decisively. As part of Samsung’s expanded Android One-like program at the time, the A40 received two major OS updates (up to Android 11) and longer security patch support. The A10 was limited to one update (Android 10) and shorter maintenance cycles.

Long-term usability depends heavily on software. Apps increasingly require newer OS versions, and outdated phones face compatibility issues. By 2023, the A10 had largely fallen out of support, making it vulnerable to security risks and limiting access to updated apps. The A40 remained functional longer, especially for users needing reliable WhatsApp, banking, or productivity tools.

Real-World Example: Maria’s Experience

Maria used her Galaxy A10 from 2019 to mid-2021. She noticed gradual slowdowns, frequent app crashes, and eventually couldn’t update essential apps like Google Maps due to OS incompatibility. When she upgraded to a used A40, she was surprised by the smoother interface and ability to install newer versions of her favorite apps. “It felt like going from dial-up to broadband,” she said. “The screen made videos pop, and I didn’t have to close everything every time I opened a new app.”

Upgrade Checklist: Should You Move to the A40?

Before deciding, consider the following checklist to evaluate whether the upgrade makes sense for your needs:

• ✅ Are you frustrated with slow app switching or constant reloads?
• ✅ Do you consume media (YouTube, Instagram, reading) regularly?
• ✅ Is your current A10 struggling with app updates or security warnings?
• ✅ Do you value photo quality, even slightly improved?
• ✅ Can you find the A40 at a reasonable price (under $100 used)?

If three or more apply, the A40 represents a meaningful upgrade.

Frequently Asked Questions

Is the Samsung A40 still supported in 2024?

No. Official software updates ended in 2021. While the phone still functions, it no longer receives security patches or OS upgrades, making it less secure over time.

Can the A40 replace a modern budget phone?

For basic tasks—calls, texts, light browsing, offline media—it can suffice temporarily. However, newer phones like the A14 or A05 offer better processors, longer support, and improved cameras at similar prices.

Does the A40 have a headphone jack?

Yes, both the A10 and A40 include a 3.5mm headphone jack and FM radio support—unlike many newer Samsung models.

Final Verdict: To Upgrade or Not?

If you’re still using a Galaxy A10 today, the answer depends on your expectations. The A40 offers tangible improvements: a superior display, double the RAM, better camera processing, and longer software support. These aren’t flashy specs—they translate into daily comfort, responsiveness, and usability.

However, if you’re buying secondhand in 2024, weigh the cost carefully. The A40 might only be $20–$30 more than the A10, but both are outdated. Consider whether investing in a newer budget model would serve you better long-term.

For existing A10 owners experiencing performance bottlenecks or display limitations, upgrading to the A40—even used—is justified. But if your A10 still meets your needs and you’re not facing app incompatibility, holding off until a more capable successor makes financial and practical sense.
