Ratings

The Samsung Galaxy A04s, released in late 2022, and the Samsung Galaxy S21 Ultra 5G, launched in early 2021, represent distinct segments within Samsung's smartphone offerings. While both operate on the Android platform with Samsung's One UI, they cater to different user expectations and needs. The primary differentiators lie in their core hardware capabilities, display technology, and advanced features, reflecting their respective positions in the market.

Scores

Durability

The expected lifespan and software support differ significantly between these two devices, largely due to their original market positioning and release timelines.

  • Release Timeline: The Galaxy S21 Ultra 5G was introduced in January 2021, making it an older flagship model, while the Galaxy A04s followed in September/October 2022. This difference in launch date impacts their remaining software support cycles.
  • Software Longevity: Flagship devices like the S21 Ultra 5G typically receive longer periods of major Android updates and security patches compared to more budget-oriented phones like the A04s. Users can generally expect the S21 Ultra 5G to receive updates for a longer duration from its release date.
  • Build Durability: The Galaxy S21 Ultra 5G features a more robust construction with Gorilla Glass Victus on both the front and back, along with an aluminum frame and an IP68 rating for dust and water resistance. The Galaxy A04s, conversely, is constructed with a glass front, plastic back, and plastic frame, offering less inherent protection against drops and environmental elements.

Performance

Performance is a key area where these two Samsung smartphones diverge, impacting how smoothly they handle various tasks and applications.

  • Processing Power: The Galaxy S21 Ultra 5G is equipped with a high-performance processor, enabling seamless multitasking, rapid app launches, and a fluid experience even with demanding applications and graphics-intensive games. The Galaxy A04s, featuring a more modest processor, is designed for essential daily tasks such as browsing, social media, and light applications. Users may experience slower app loading times and occasional stutters, particularly when engaging in heavy multitasking or more complex gaming.
  • Multitasking and Responsiveness: The S21 Ultra 5G offers ample RAM configurations, contributing to its ability to manage numerous applications simultaneously without significant slowdowns. The A04s comes with lower RAM options, which can limit its capacity for smooth transitions between many open apps, potentially leading to more frequent app reloads.
  • Storage Options: The S21 Ultra 5G provides generous internal storage capacities, though it lacks a microSD card slot for expansion. The A04s offers smaller internal storage options but includes a dedicated microSDXC slot, allowing users to expand storage for photos, videos, and other files.

Screen quality

The visual experience offered by these two devices varies significantly due to their differing display technologies and specifications.

  • Display Technology and Clarity: The Galaxy S21 Ultra 5G features a 6.8-inch Dynamic AMOLED 2X display, known for its vibrant colors, deep blacks, and high contrast. This results in a rich and immersive viewing experience. The Galaxy A04s uses a 6.5-inch PLS LCD panel, which provides adequate colors but does not achieve the same level of contrast or black depth as an AMOLED screen.
  • Resolution and Brightness: The S21 Ultra 5G boasts a high resolution of 1440 x 3200 pixels (WQHD+), delivering exceptionally sharp images and text, along with a peak brightness of 1500 nits, ensuring excellent visibility even in bright outdoor conditions. The A04s has a resolution of 720 x 1600 pixels (HD+), which is sufficient for general use but may show some pixelation with fine details. Its peak brightness of around 400 nits can make outdoor viewing challenging in direct sunlight.
  • Refresh Rate: The S21 Ultra 5G offers an adaptive refresh rate that can dynamically adjust between 10Hz and 120Hz, providing smooth scrolling and responsive interactions while optimizing battery consumption. The A04s features a 90Hz refresh rate, which offers a smoother experience than standard 60Hz displays, though it may not always maintain this rate consistently due to processor limitations.

Audiovisual

The camera systems on the Galaxy A04s and Galaxy S21 Ultra 5G are designed for different photographic needs and offer distinct capabilities.

  • Rear Camera System: The Galaxy S21 Ultra 5G features a versatile quad-camera setup, including a 108 MP main sensor with optical image stabilization (OIS), a 12 MP ultrawide lens, and two 10 MP telephoto lenses offering 3x and 10x optical zoom, also with OIS. This configuration allows for detailed photos across various focal lengths, including impressive zoom capabilities and 8K video recording. The Galaxy A04s comes with a triple-camera system, comprising a 50 MP main sensor, a 2 MP macro lens, and a 2 MP depth sensor. This setup is suitable for everyday photography, capturing decent daylight shots.
  • Low-Light and Video Performance: The S21 Ultra 5G excels in low-light conditions due to its larger sensor and OIS, producing clearer and more detailed images. Its advanced video features, such as 8K recording and Director's View, provide extensive creative control. The A04s performs adequately in well-lit environments, but its low-light performance is more limited, and it lacks advanced video stabilization or high-resolution recording options.
  • Front Camera and Audio: For selfies and video calls, the S21 Ultra 5G includes a high-resolution 40 MP front camera. The A04s has a 5 MP front camera, which is functional for basic use. The S21 Ultra 5G offers a more refined audio experience for media consumption and calls, while the A04s provides a single mono speaker that is clear for voices but less rich for music.

Miscellaneous

Beyond core performance and display, several practical features and design elements differentiate these two Samsung smartphones.

  • Connectivity and Ports: The Galaxy S21 Ultra 5G supports advanced connectivity standards, including 5G for faster mobile data, Wi-Fi 6E for enhanced wireless internet, and Bluetooth 5.2. It features a USB-C 3.2 port. The Galaxy A04s supports 4G LTE networks, Wi-Fi 5 (802.11 a/b/g/n/ac), and Bluetooth 5.0. It includes a USB-C 2.0 port and retains a 3.5mm headphone jack.
  • Biometric Security: The S21 Ultra 5G incorporates an ultrasonic in-display fingerprint sensor for convenient and secure unlocking. The A04s features a side-mounted fingerprint sensor integrated into the power button.
  • Design and Handling: The S21 Ultra 5G has a premium feel with its glass and aluminum construction, though its larger size and weight can make it feel substantial in hand. The A04s, with its plastic build, is lighter but may feel less premium. Its dimensions are also considerable, and some users find it thick.
  • Additional Features: The S21 Ultra 5G offers S Pen support, expanding its utility for note-taking and drawing, though the S Pen is sold separately. The A04s includes a dedicated microSD card slot for expandable storage, a feature absent on the S21 Ultra 5G.

User feedback for the Samsung Galaxy A04s often highlights its strong battery life as a significant advantage, with many reporting it comfortably lasts a full day or more with moderate use. Its 90Hz display is also frequently praised for offering a smoother visual experience than many devices in its category. However, common criticisms revolve around its performance, with users noting sluggishness and struggles with multitasking, particularly with more demanding applications. The display's lower resolution and brightness are also points of concern for some.

The Samsung Galaxy S21 Ultra 5G consistently receives acclaim for its exceptional camera system, especially its versatile zoom capabilities, and its stunning, bright, and high-resolution AMOLED display. Its powerful performance and premium build quality are also frequently lauded. While its battery life is generally considered good, some users have noted that enabling the highest resolution and refresh rate settings can lead to faster drain. The absence of a charger in the box and a microSD card slot are also occasional points of discussion.

Users prioritizing extended battery life and essential smartphone functions for daily communication and light media consumption may find the Galaxy A04s well-suited to their needs. Conversely, individuals who require a high-performance device for advanced photography, demanding applications, immersive media viewing, and a premium user experience will likely lean towards the Galaxy S21 Ultra 5G. Both devices offer distinct advantages, and considering a quality-assured refurbished option can provide an eco-friendly alternative for either model.
