1. Introduction: Context and Overview

1.1. The Galaxy A-Series

The Samsung Galaxy A36 5G is part of Samsung’s A-series, which is positioned in the mid-range segment of the smartphone market. This series is designed to offer solid performance and modern features without the premium price tag of the Galaxy S-series. The A36 5G aims to cater to users who are looking for a well-rounded smartphone experience, including 5G connectivity, a reliable camera system, and a good balance of performance and battery life, all at a more affordable price.

1.2. The Galaxy S-Series

On the other hand, the Samsung Galaxy S25 belongs to the flagship S-series, which represents the pinnacle of Samsung’s smartphone technology. The S-series includes the latest innovations in display technology, camera systems, processing power, and overall design. It is targeted toward users who are willing to pay a premium for the best performance, most advanced features, and superior build quality. The S25, as part of the S-series, is expected to showcase top-of-the-line hardware and software, delivering an exceptional user experience.

2. Design and Build Quality

2.1. Galaxy A36 5G Design

The Galaxy A36 5G aims for a modern, sleek design, but with materials that help keep its price competitive. Typically, the A-series uses a polycarbonate (plastic) back panel instead of glass, and an aluminum frame. While not as premium as the all-glass construction of higher-end phones, plastic provides a lightweight build, making it more durable in terms of resistance to shattering when dropped.

• Dimensions and Weight: The A36 5G is compact and weighs about 180 grams. With a 6.4-inch display, it strikes a balance between large screen size and portability.
• Durability: One of the standout features of the A36 is its IP67 rating, which means it’s resistant to dust and can withstand immersion in water up to 1 meter for 30 minutes. This is a feature that is typically reserved for more premium devices and provides extra peace of mind for users.

2.2. Galaxy S25 Design

The Galaxy S25, as a flagship device, will have a more premium design. Expect a glass back (likely using Gorilla Glass Victus or similar material) paired with a metal frame, making the phone feel more high-end. The design will also be more refined, with slimmer bezels and cutting-edge finishes.

• Dimensions and Weight: The S25 will likely be slightly more compact than the A36, possibly around 6.1 inches, which fits comfortably in one hand. Its weight will be heavier, around 169-175 grams, primarily due to the premium materials used.
• Durability: The S25 is expected to have an IP68 rating, providing better protection against water and dust (up to 1.5 meters of water for 30 minutes), making it ideal for more rugged usage.

2.3. Color Options

The A36 may come in a variety of color options such as Black, White, and Blue, offering consumers a sense of choice in a lower-budget category. Meanwhile, the S25 will likely offer more refined, premium hues such as Phantom Black, Phantom White, and special-edition colors.

3. Display Technology and Quality

3.1. Galaxy A36 5G Display

The Galaxy A36 features a 6.4-inch Super AMOLED display with a FHD+ resolution (1080 x 2400 pixels). Super AMOLED technology offers vivid colors, deeper blacks, and higher contrast ratios compared to traditional LCD panels. Additionally, the A36 supports a 90Hz refresh rate, which enhances the smoothness of animations and scrolling.

• Display Quality: While the A36 provides solid color accuracy and decent peak brightness, it’s not as advanced as higher-end models. For everyday tasks like browsing, media consumption, and light gaming, the display is more than adequate.
• Refresh Rate: The 90Hz refresh rate is a nice touch, especially when compared to traditional 60Hz displays, but it’s still behind the 120Hz displays found in flagship models.

3.2. Galaxy S25 Display

The Galaxy S25, as expected, will come with a 6.1-inch Dynamic AMOLED 2X display. Dynamic AMOLED 2X improves on the Super AMOLED by offering better brightness, more accurate colors, and deeper blacks. The S25 will likely have a Quad HD+ resolution (1440 x 3200 pixels), offering sharper visuals than the A36.

• Display Quality: Expect exceptional color accuracy, HDR10+ support for rich media content, and a high peak brightness of over 1200 nits for outdoor visibility.
• Refresh Rate: The S25 will feature an adaptive 120Hz refresh rate, meaning it can switch between 60Hz, 90Hz, and 120Hz depending on the content being displayed. This optimizes both performance and battery life.

4. Performance and Processing Power

4.1. Galaxy A36 5G Performance

The Galaxy A36 is powered by the MediaTek Dimensity 1080 chipset, a mid-range SoC that supports 5G connectivity. This chip, paired with 6GB or 8GB of RAM and 128GB of internal storage, offers reliable performance for most daily tasks, including web browsing, video streaming, and some light gaming.

• Processor Performance: The Dimensity 1080 is optimized for efficiency and 5G, but it’s not designed for heavy-duty gaming or intense multitasking.
• Gaming: With the Mali-G68 MC4 GPU, the A36 can handle casual games like PUBG Mobile or Asphalt 9 at medium settings, but for more graphically demanding games, the experience might not be as smooth.

4.2. Galaxy S25 Performance

The Galaxy S25, being a flagship device, will feature either the Qualcomm Snapdragon 8 Gen 3 (for North America) or Exynos 2400 (for other regions). These chips are built for top-tier performance, including gaming, video editing, and multitasking.

• Processor Performance: The Snapdragon 8 Gen 3 (or Exynos equivalent) is built for power users and heavy multitaskers, offering massive improvements in CPU and GPU performance over previous generations.
• Gaming: With the Adreno 740 (or Mali-G78 MP24) GPU, the S25 can easily handle AAA games like Call of Duty Mobile, Genshin Impact, and PUBG Mobile at high settings with ease.

5. Camera Systems

5.1. Galaxy A36 5G Camera

The A36 5G will likely feature a 50MP primary camera paired with an 8MP ultra-wide and 2MP depth sensor. The camera setup is designed for decent photo quality in good lighting, with the ability to capture wide-angle shots and portrait mode.

• Main Camera: The 50MP camera will offer sharp, detailed photos in well-lit conditions. However, it might struggle in low light without advanced processing software like night mode.
• Video Recording: The A36 supports 4K video recording at 30fps, which is typical for mid-range smartphones. It lacks the high-end video features found in flagship models like 8K recording or advanced stabilization.

5.2. Galaxy S25 Camera

The S25 is expected to feature a 200MP primary camera, which would be one of the highest resolutions available on a smartphone. This would offer incredible detail, especially when zooming in on photos. Additionally, the S25 will likely feature an ultra-wide camera (12MP or higher) and a 10MP telephoto camera with optical zoom.

• Main Camera: The 200MP sensor would allow users to crop images without losing detail, providing extreme flexibility. It is also expected to perform exceptionally well in low-light conditions, thanks to advanced sensors and AI processing.
• Video Recording: The S25 is likely to support 8K video recording, alongside 4K at 60fps and Super Steady video for ultra-smooth footage. With its advanced stabilization system, the S25 will provide professional-grade video recording.

6. Battery Life and Charging

6.1. Galaxy A36 5G Battery

The A36 5G is expected to come with a 5000mAh battery, which should easily last a full day on moderate usage. Thanks to the efficiency of the MediaTek Dimensity 1080 chip, the phone can conserve power without sacrificing performance.

• Charging Speed: The A36 will likely support 25W fast charging, which is fairly standard for mid-range devices. Wireless charging may not be available in this price range.

6.2. Galaxy S25 Battery

The S25 may
