The Samsung Galaxy S series has been a popular choice among smartphone users, offering cutting-edge features and powerful performance. In this article, we will compare the attributes of two notable models from this series - the Galaxy S II and the Galaxy S3. Both devices have their own unique strengths and weaknesses, and understanding their differences can help users make an informed decision when choosing between the two.

Design and Display

When it comes to design, the Galaxy S II features a sleek and slim profile with a plastic back cover. It sports a 4.3-inch Super AMOLED Plus display, which offers vibrant colors and deep blacks. On the other hand, the Galaxy S3 takes design cues from nature with its pebble-inspired design and a glossy polycarbonate back cover. It boasts a larger 4.8-inch Super AMOLED HD display, providing a more immersive viewing experience with its higher resolution and larger size.

In terms of build quality, the Galaxy S3 feels more solid and premium compared to its predecessor. The larger display of the S3 also gives it a more modern and visually appealing look. However, some users may prefer the compactness and lightweight nature of the Galaxy S II, making it easier to handle with one hand.

Performance and Hardware

Under the hood, the Galaxy S II is powered by a dual-core 1.2 GHz Exynos processor, coupled with 1GB of RAM. While it may not match the processing power of newer smartphones, it still delivers smooth performance for everyday tasks and moderate multitasking. On the other hand, the Galaxy S3 steps up the game with a quad-core 1.4 GHz Exynos processor (or a dual-core Snapdragon S4 processor in some regions) and 1GB of RAM. This upgrade results in snappier performance, better multitasking capabilities, and improved gaming experiences.

Both devices offer expandable storage options via microSD cards, allowing users to easily increase their storage capacity. The Galaxy S II supports up to 32GB of external storage, while the Galaxy S3 can handle up to a whopping 64GB. This is particularly beneficial for users who require ample space for storing multimedia files, such as photos, videos, and music.

Camera Capabilities

Photography enthusiasts will appreciate the camera capabilities of both the Galaxy S II and the Galaxy S3. The Galaxy S II features an 8-megapixel rear camera with autofocus and LED flash, capable of capturing high-quality images even in low-light conditions. It also supports 1080p video recording, allowing users to shoot stunning videos.

The Galaxy S3, on the other hand, takes it a step further with its 8-megapixel rear camera, which is equipped with advanced features like zero shutter lag, burst mode, and simultaneous HD video and image recording. It also introduces a front-facing 1.9-megapixel camera, enabling users to take high-resolution selfies and engage in video calls.

Both devices offer a range of camera modes and settings, allowing users to unleash their creativity and capture memorable moments with ease.

Software and User Interface

When it comes to software, the Galaxy S II originally shipped with Android 2.3 Gingerbread, which can be upgraded to Android 4.1 Jelly Bean. It features Samsung's TouchWiz user interface, which provides a user-friendly experience with its intuitive design and customization options.

The Galaxy S3, on the other hand, comes with Android 4.0 Ice Cream Sandwich out of the box, which can be upgraded to newer versions of Android. It introduces a refined version of TouchWiz, offering additional features and enhancements. One notable feature is Smart Stay, which uses the front-facing camera to detect the user's eye movement and keeps the screen on as long as they are looking at it.

Both devices provide access to the Google Play Store, allowing users to download a wide range of apps, games, and utilities to enhance their smartphone experience.

Battery Life and Connectivity

Battery life is an important consideration for smartphone users, and both the Galaxy S II and the Galaxy S3 offer decent battery performance. The Galaxy S II is equipped with a 1650mAh battery, which provides sufficient power to last through a day of moderate usage.

The Galaxy S3, on the other hand, features a larger 2100mAh battery, offering improved battery life compared to its predecessor. The more efficient processor and software optimizations contribute to a longer-lasting battery, ensuring users can stay connected for longer periods without worrying about running out of power.

In terms of connectivity, both devices support 3G and Wi-Fi connectivity, allowing users to browse the internet, stream media, and stay connected on the go. The Galaxy S3, however, introduces 4G LTE support in some variants, enabling faster download and upload speeds for users in areas with 4G coverage.


In conclusion, the Galaxy S II and the Galaxy S3 are both impressive smartphones with their own set of strengths and weaknesses. The Galaxy S II offers a compact design, solid performance, and a capable camera, making it a reliable choice for users who prioritize portability and affordability.
