Is The Samsung A8 2018 Really Worth Upgrading From The A7 2017

For users still relying on the Samsung Galaxy A7 (2017), the idea of upgrading to the Galaxy A8 (2018) might seem like a natural progression. After all, newer models often promise better performance, improved design, and enhanced features. But in the mid-range smartphone segment, where price sensitivity is high and differences between generations can be subtle, the upgrade decision isn’t always straightforward. This article dives deep into the practical differences between these two devices—examining hardware, software, user experience, and long-term value—to determine whether the jump from the A7 2017 to the A8 2018 truly makes sense.

Design and Build: A Step Toward Modernity

The most immediate difference between the A7 2017 and the A8 2018 lies in their design language. The A7 2017, while solidly built with a glass front and back and a metal frame, adheres to a more traditional smartphone aesthetic. It features physical navigation buttons and a standard 16:9 aspect ratio display, which by 2018 was already becoming outdated.

In contrast, the A8 2018 embraces the design trends of its time. It introduces an Infinity Display with slimmer bezels and an 18.5:9 aspect ratio, giving it a more modern, elongated look. The device also swaps physical buttons for on-screen navigation, freeing up front space and improving usability with one hand. While both phones are water-resistant (IP68 on the A7 2017, IPx8 on the A8 2018), the A8 lacks dust resistance certification, a slight downgrade in ruggedness.

Tip: If you prioritize screen real estate and a contemporary design, the A8 2018’s Infinity Display offers a noticeably more immersive experience than the boxier A7 2017.

Display and Usability Comparison

The A7 2017 sports a 5.7-inch Full HD (1080x1920) Super AMOLED display, which remains sharp and vibrant. However, the A8 2018 ups the ante with a larger 5.6-inch Full HD+ (1080x2220) Super AMOLED panel. Despite being slightly smaller in diagonal measurement, the A8’s taller aspect ratio provides more vertical content space, beneficial for scrolling through social media, emails, or web pages.

Both displays use Samsung’s excellent Super AMOLED technology, so color accuracy, contrast, and viewing angles are top-tier for their class. However, the A8’s higher resolution per inch and optimized layout make it feel more future-proof, especially as app interfaces increasingly adapt to taller screens.

Performance: Is the Upgrade Noticeable?

Under the hood, the A7 2017 uses the Exynos 7880 octa-core processor paired with 3GB of RAM. It handles everyday tasks well but can struggle with heavier multitasking or demanding games. The A8 2018, meanwhile, steps up to the Exynos 7885 (in some regions) or Snapdragon 660 (in others), depending on market, coupled with 4GB of RAM.

This shift brings tangible improvements. Apps launch faster, background app retention is better, and overall system fluidity feels smoother. Users coming from the A7 2017 will notice reduced stutter during transitions and improved responsiveness in gaming and video playback. However, neither chip qualifies as a powerhouse—both sit firmly in the mid-tier bracket.

Camera Evolution: More Than Just Megapixels

On paper, the camera specs appear similar: both devices feature a 16MP rear sensor and an 8MP front camera. However, the A8 2018 introduces Samsung’s “Live Focus” feature on the front camera—a rarity at the time for mid-range phones. This allows users to capture portrait-mode selfies with adjustable bokeh, enhancing selfie quality significantly.

The rear camera sees modest improvements in low-light processing and autofocus speed, thanks to software optimizations and a slightly larger pixel size. Image stabilization remains absent on both models, so handheld low-light shots may suffer from blur.

In real-world use, the A8 2018 produces slightly crisper images with better dynamic range, particularly in mixed lighting. The addition of AR stickers and beautification modes adds fun, albeit gimmicky, functionality that appeals to younger users.

Battery Life and Charging

The A7 2017 packs a 3600mAh battery, which was generous for its time and typically lasts a full day with moderate use. The A8 2018, despite a sleeker profile, includes a slightly smaller 3000mAh cell. This reduction, combined with a higher-resolution display and more power-hungry processor, results in shorter battery life under comparable usage.

Neither model supports fast charging out of the box, relying on standard 5V/2A charging. As a result, the A8 2018 may require more frequent top-ups, especially for heavy users. This trade-off—slimmer design for reduced endurance—is a key consideration when evaluating the upgrade.

Tip: If battery longevity is a priority, the A7 2017 remains superior. Consider keeping it longer or pairing the A8 2018 with a portable charger.

Real-World Example: Sarah’s Upgrade Dilemma

Sarah had used her A7 2017 for nearly two years. It still worked fine, but she found herself frustrated by slow app launches and limited photo effects for Instagram. When she saw a discounted A8 2018, she considered upgrading. After testing both side-by-side, she noticed the A8’s interface felt snappier and loved the Live Focus selfies. However, she quickly realized the smaller battery meant charging twice a day during work hours. Ultimately, she decided to keep her A7 2017 and install a lightweight Android launcher to improve speed—saving money and reducing e-waste.

Sarah’s story reflects a common reality: perceived benefits don’t always translate into meaningful daily improvements. For many users, optimizing the current device may offer better value than a marginal hardware upgrade.

Upgrade Checklist: Should You Make the Move?

• ✅ Need a more modern, edge-to-edge display?
• ✅ Want better selfie capabilities with bokeh effects?
• ✅ Frustrated by app lag or multitasking limitations?
• ❌ Concerned about shorter battery life?
• ❌ Still satisfied with your A7 2017’s performance?
• ❌ On a tight budget or minimal price difference?

If most checks are positive, the A8 2018 could enhance your experience. If negatives dominate, staying put—or investing in a more significant upgrade—is wiser.

Frequently Asked Questions

Can the A8 2018 run modern apps smoothly in 2024?

Yes, but with limitations. Basic apps like WhatsApp, Chrome, and Gmail run adequately, but newer versions of games or productivity tools may lag. Performance depends heavily on background processes and storage availability.

Does the A8 2018 support software updates anymore?

No. Both the A7 2017 and A8 2018 have reached end-of-life for official Android updates. They no longer receive security patches, posing potential risks for online banking or sensitive data use.

Is the build quality better on the A8 2018?

Subjectively, yes—it looks more premium with its slim bezels and glossy finish. However, the A7 2017’s IP68 rating and larger battery give it an edge in durability and practicality.

Final Verdict: Is the Upgrade Worth It?

The Samsung A8 2018 represents an evolutionary step from the A7 2017, not a revolution. It improves in key areas—design, front camera, and multitasking—but sacrifices battery capacity and dust resistance. For users deeply invested in selfies and modern aesthetics, the upgrade brings noticeable benefits. However, if your A7 2017 still performs reliably, the gains may not justify the cost or environmental impact of replacing a functional device.

Consider this: instead of upgrading to another aging mid-ranger, could your budget stretch toward a newer entry-level phone with longer support and better efficiency? Devices like the Galaxy A14 or even refurbished flagships now offer more future-proof value.
