Quick answer: what is the Samsung Galaxy A8 (2018)
The Samsung Galaxy A8 (2018) is a mid-range Android phone from Samsung’s Galaxy A series, announced in late 2017 and released in 2018. It is distinguished by an all‑display front design with minimal bezels, an aluminum frame, and dual‑camera setup. Compared with the standard Galaxy A8, the A8 (2018) features a larger 5.6‑inch Full HD+ display, a 1.9GHz octa‑core processor, 4GB of RAM, and improved cameras. It runs Samsung’s Grace UX and emphasizes a premium look and balanced performance for everyday use.
Verified overview and brand context
Samsung positions the Galaxy A series as its volume‑friendly tier that brings flagship‑inspired design and features to a broader audience. The Galaxy A line has historically emphasized sleek metal chassis, high‑screen‑to‑body ratios, and cameras tuned for everyday use. The A8 (2018) fits within this strategy as a device that upgrades the A8 with a nearly borderless display and refined internals. Its specifications and feature set are well documented in Samsung press releases and hands‑on reviews from 2017–2018.
Design and build quality
Exterior and materials
The Galaxy A8 (2018) uses an aluminum frame with glass accents on the front and back, supported by slim metal antenna lines. The device is relatively compact for its screen size, with curved edges intended to improve one‑handed use. The front display is nearly bezel‑less thanks to narrow borders, while the rear camera module is subtly raised and protected by a small glass circle.
- Dimensions: Around 149.2 x 70.6 x 7.9 mm
- Weight: Approximately 175 g
- Colors: Often available in richer tones such as Prism Blue, Prism Black, and Gold
Display and ergonomics
It features a 5.6‑inch Super AMOLED display with Full HD+ resolution (2220 x 1080), delivering vivid colors and deep blacks typical of Samsung’s premium screens. The display glass is covered by Corning Gorilla Glass 5, offering good scratch and drop resistance for daily use. The front‑display design reduces bezels significantly compared to earlier A‑series phones, improving the viewing experience for media and browsing.
Camera system and imaging
Rear camera
The rear setup pairs a 16MP sensor with a wide‑aperture f/1.7 lens and phase detection autofocus. In daylight, images show good detail, accurate colors, and acceptable dynamic range. Low‑light performance is enhanced by larger pixels and OIS on some variants, though noise can become visible at higher ISOs. The camera app includes Pro mode for manual control and supports 4K video recording at 30fps.
Front camera
The hallmark of the A8 (2018) is its front camera: a dual‑camera array with a 16MP RGB and an 8MP depth sensor. This enables portrait‑style selfies with background blur (Live Focus), face detection, and beauty modes. The front flash uses the screen as a flashlight in some modes. Selfie quality is generally strong for the class, with good skin tone preservation and sharpness under even lighting.
Performance, software, and usability
Processor and RAM
Power comes from an octa‑core processor, commonly the Exynos 7885 in many regions, paired with 4GB of LPDDR4 RAM. This combination handles multitasking, social apps, and light gaming without noticeable lag.日常使用中，应用冷启动时间和界面滚动流畅度表现均衡。存储方面，提供64GB内置存储，并可通过microSD卡扩展至256GB。
Battery and connectivity
Battery capacity is rated at 3000mAh, which comfortably supports a full day of mixed use with adaptive battery optimizations. Connectivity includes dual‑SIM support (nano‑SIM), LTE Cat.7, Wi‑Fi 802.11ac, Bluetooth 5.0, GPS, and NFC. The device supports Samsung Pay MST and includes a side‑fingerprint sensor for quick unlocking.
Comparisons and positioning
In the 2018 A‑series lineup, the Galaxy A8 (2018) sits between the more compact A5 (2018) and the larger A8+ (2018). The A8 prioritizes a balanced screen size and everyday usability, whereas the A8+ offers a bigger screen and battery, and the A5 focuses on affordability. Compared with older A8 models, the 2018 refresh brings a noticeably higher screen‑to‑body ratio and faster charging support.

Reliability, support, and status
Software updates and security
The Galaxy A8 (2018) received major Android updates up to Android 9 (Pie) with Samsung’s Grace UX. For ongoing use, it continues to receive periodic security patches when supported in your region. Performance on later Android versions is generally stable, though some heavy multitasking scenarios may show the age of the hardware in very busy workflows.
Repairability and parts availability
Back glass and battery replacement are typically available from both OEM and reputable third‑party providers. Because the device uses a non‑user‑replaceable battery, DIY replacement carries some risk, and screen or glass repairs should be handled by trained technicians to preserve display quality.
Practical verdict and legacy
In daily use today, the Galaxy A8 (2018) remains a capable secondary phone or an affordable entry into Samsung’s premium design language. The combination of a near‑borderless display, competent cameras, and solid build quality delivers a coherent experience for browsing, messaging, and media. While it does not match current mid‑range performance for demanding games, it is well suited for light tasks, social apps, and as an accessible way to experience Samsung’s ecosystem features.
