Design and Display: A Practical Aesthetic

The Samsung Galaxy A42 5G, like many of its A-series brethren, aims for a balance between modern aesthetics and cost-effectiveness.

It doesn’t scream “premium flagship,” but it certainly doesn’t feel cheap.

Samsung made some smart choices here to keep the price competitive while still delivering a satisfying visual experience.

Visual Appeal and Build Materials

The A42 5G boasts a design that’s distinctly Samsung, yet with a playful twist. The most notable aspect of its rear panel is the quad-patterned finish, which separates the back into four distinct segments, each with a slightly different hue or reflectivity. This gives it a unique, almost gradient-like effect that catches the light differently depending on the angle. It’s certainly more eye-catching than a plain matte or glossy back.

Back Panel: Primarily made of “Glasstic,” Samsung’s term for a high-quality polycarbonate. While not glass, it has a good heft and feels reasonably durable. It’s less prone to shattering than glass, which is a practical benefit for many users. The finish does tend to be a bit of a fingerprint magnet, so having a case or wiping it down regularly might be on your task list.
Frame: The frame is also polycarbonate, designed to mimic a metallic finish. It feels sturdy in hand and provides a comfortable grip.
Dimensions and Weight: At 164.4 x 75.9 x 8.6 mm and weighing 193 grams, it’s a relatively large and substantial device. This is common for phones with large batteries and displays. It feels solid, not flimsy, which is a good sign of build quality in this price range.

The Super AMOLED Experience

One of the A42 5G’s standout features, particularly at its price point, is the inclusion of a 6.6-inch Super AMOLED display. This is a significant win, as many competitors in this segment often opt for LCD panels to save costs. AMOLED technology brings a host of benefits:

Vibrant Colors: Super AMOLED displays are renowned for their vivid, saturated colors, making media consumption, browsing photos, and gaming a more immersive experience.
True Blacks: Unlike LCDs that require a backlight, AMOLED pixels can turn off individually, resulting in absolute blacks. This creates fantastic contrast and makes dark mode experiences truly dark.
Excellent Contrast: The combination of true blacks and vibrant colors leads to incredibly high contrast ratios, making images pop and text sharper.
Always-On Display AOD: Thanks to the power efficiency of AMOLED, the A42 5G supports Samsung’s Always-On Display, allowing you to see time, date, battery status, and notifications without fully waking the screen. This is a highly convenient feature.

However, it’s not all sunshine and roses. The display has a 720p+ resolution HD+ 720 x 1600 pixels. While for most everyday use, this resolution is acceptable, especially on a screen of this size, pixel peepers might notice a slight lack of sharpness compared to a Full HD+ 1080p+ display. For example, text might appear slightly less crisp, and fine details in high-resolution images or videos might not be as pronounced. But for general browsing, social media, and streaming standard definition content, it’s perfectly adequate.

The display also features a standard 60Hz refresh rate. While many newer mid-range phones are moving towards 90Hz or 120Hz for smoother scrolling and animations, 60Hz is still the industry standard for budget and many mid-range devices. It’s not a deal-breaker unless you’re accustomed to higher refresh rates.

Overall, the design of the A42 5G is practical and visually distinct, while the Super AMOLED display offers a compelling visual experience despite its resolution limitation.

It’s a smart trade-off by Samsung to deliver core benefits without escalating the price.

Camera System: Versatility in the Mid-Range

Samsung has historically equipped its A-series phones with versatile camera setups, and the Galaxy A42 5G is no exception.

It features a quad-camera array on the rear, aiming to provide options for various shooting scenarios, along with a capable front-facing camera.

Rear Camera Setup

The quad-camera module on the back consists of:

48MP Main Sensor:
- Aperture: f/1.8
- Features: This is the primary shooter, often using pixel-binning technology Tetra Binning in Samsung’s case, combining four pixels into one to produce brighter and clearer 12MP photos by default. You can usually shoot in full 48MP mode if you need more detail, though these files will be larger.
- Performance in Good Light: In well-lit conditions, the 48MP main sensor captures detailed photos with good dynamic range and Samsung’s signature vibrant color science. Photos are generally sharp and ready for social media.
- Performance in Low Light: Low-light performance is acceptable for a mid-range phone. It has a dedicated Night Mode that helps brighten scenes and reduce noise, though results can be hit or miss and often require a steady hand. Don’t expect flagship-level low-light photography, but it’s usable for casual shots.
8MP Ultra-Wide Sensor:
- Aperture: f/2.2
- Performance: Ultra-wide shots are decent in good lighting, but quality takes a noticeable dip compared to the main sensor. Details are softer, and dynamic range can be more limited. In low light, it struggles significantly. There can also be some barrel distortion at the edges, which is common for ultra-wide lenses.
5MP Macro Sensor:
- Aperture: f/2.4
- Function: Designed for extreme close-up photography, allowing you to get very near to small subjects typically 3-5cm away to capture intricate details.
- Utility: While it adds to the “quad-camera” count, the utility of this macro lens is often debatable. The 5MP resolution limits detail, and it can be tricky to get the subject in focus. Many users might find more success by simply cropping in on a photo taken with the main sensor.
5MP Depth Sensor:
- Function: This sensor does not capture images itself. Instead, it assists the main camera in gathering depth information, primarily for Live Focus portrait mode. It helps create a more convincing background blur bokeh effect around your subject.
- Performance: The depth sensor generally performs well in isolating subjects from the background, especially in good lighting. Edge detection is reasonably good, though complex outlines like messy hair can sometimes be a challenge.

Front Camera

20MP Front Sensor:
- Features: This sensor is capable of taking detailed selfies. It also supports Live Focus for blurred backgrounds in selfies.
- Performance: In good lighting, selfies are sharp with good color reproduction. Like the rear cameras, performance degrades in low light, though Samsung’s software often tries to compensate.

The Galaxy A42 5G supports:

Rear Camera Video: Up to 4K at 30fps or 1080p at 30/60fps.
Front Camera Video: Up to 1080p at 30fps.

While 4K video recording is available, it lacks optical image stabilization OIS, relying solely on electronic image stabilization EIS. This means video footage can be a bit shaky if you’re not holding the phone very still, especially in 4K.

For smoother video, 1080p at 30fps with EIS is often a more stable option.

Camera Software Features

Samsung’s camera app is feature-rich, offering various modes:

Pro Mode: Allows manual control over ISO, white balance, exposure, etc. though not as extensive as on flagships.
Panorama: For wide scenic shots.
Food Mode: Optimizes colors and focus for food photography.
Slow Motion and Hyperlapse: For creative video effects.
AR Doodle/AR Zone: Fun augmented reality features.

In summary, the Samsung Galaxy A42 5G’s camera system is versatile but not class-leading. The 48MP main sensor is the star, delivering solid results in good light. The ultra-wide is useful, and the depth sensor aids portraits. The macro sensor is more of a bonus. For everyday photography and social media sharing, it’s more than sufficient, but serious photography enthusiasts might look for more advanced options in higher price tiers.

Battery Life and Charging: A Marathon Runner

One of the undeniable strong suits of the Samsung Galaxy A42 5G is its impressive battery life.

Packed with a substantial cell and leveraging efficient components, this phone is designed to keep you going for extended periods without frantically searching for a power outlet.

Accessories and Ecosystem: Enhancing the A42 5G Experience

While the Samsung Galaxy A42 5G is a capable device on its own, its utility and longevity can be significantly enhanced with the right accessories.

Furthermore, being part of the broader Samsung ecosystem opens up some convenient integration possibilities.

Essential Accessories for the A42 5G

Protective Case:
- Why it’s essential: The “Glasstic” back, while durable, can still scratch, and accidental drops are always a risk. A good case provides crucial protection against bumps, drops, and scratches.
- Types:
  - Clear TPU cases: Offer basic protection while showing off the phone’s unique back design.
  - Rugged cases: Provide maximum drop protection, often with reinforced corners.
  - Wallet cases: Combine phone protection with slots for cards and cash.
- Recommendation: Given the unique back design, a clear case can be a good starting point to appreciate the aesthetic while keeping it safe.
Screen Protector:
- Why it’s essential: The display, despite being durable, is still susceptible to scratches from keys, coins, or accidental falls. A screen protector acts as a sacrificial layer.
  - Tempered glass: Offers superior scratch and impact protection, feels like the original screen.
  - TPU film: Thinner, self-healing properties for minor scratches, less impact protection.
- Consideration: With an under-display fingerprint sensor, choosing a screen protector that is compatible with it is crucial. Many tempered glass protectors for in-display sensors come with an adhesive circle or require specific installation for optimal performance.
MicroSD Card:
- Why it’s essential: The A42 5G supports expandable storage up to 1TB. While 128GB internal storage is generous, heavy users especially those who take many photos/videos or download large files will quickly appreciate the extra space.
- Benefits: Offload photos, videos, podcast, and documents, keeping your internal storage free for apps and system files, which can help maintain performance.
- Recommendation: A Class 10 or U3 UHS Speed Class 3 card ensures fast read/write speeds for smooth operation, especially for 4K video recording.
15W USB-C Charger if not included or as backup:
- Why it’s essential: While the phone supports 15W fast charging, having a spare charger for work, travel, or a multi-device household is always convenient. Ensure it’s a reputable brand.
Wireless Earbuds or Wired Headphones:
- Why it’s essential: To fully enjoy multimedia content, especially given the phone’s single speaker.
- Wired: The A42 5G retains the 3.5mm jack, so if you have a favorite pair, you’re good to go.
- Wireless: If you prefer cord-free convenience, a good pair of Bluetooth earbuds will pair seamlessly. Consider Samsung’s Galaxy Buds series for optimized integration.
