The Samsung Galaxy J5 (2017) brings a host of improvements and refinements over its predecessor, the Galaxy J5 (2016), enhancing both performance and user experience. Design-wise, the J5 (2017) adopts a more premium metal unibody construction, offering a sleeker and sturdier appearance compared to the plastic build of the previous model. This change not only elevates the aesthetic appeal but also enhances durability. The device is available in several vibrant color options, appealing to a wide range of users.Display enhancements include a 5.2-inch Super AMOLED screen that offers improved color accuracy and better viewing angles. While the resolution remains similar at HD (1280 x 720 pixels), the brightness and contrast ratio have been optimized, enabling clearer visibility in bright sunlight.Under the hood, the Galaxy J5 (2017) is powered by an upgraded Exynos 7870 octa-core processor, which provides a boost in performance and energy efficiency. This is paired with 2GB or 3GB of RAM, allowing for smoother multitasking and better handling of applications, a noticeable improvement over the 2016 model's specifications. Additionally, the storage capacity options have been expanded, offering variants with 16GB or 32GB of internal storage, expandable via microSD for increased versatility.One of the significant upgrades in the camera department is the inclusion of a 13MP rear camera with f/1.7 aperture, enhancing low-light photography capabilities compared to the f/1.9 lens in the previous generation. The front-facing camera has also been improved to 13MP, making it an ideal choice for selfies and video calls. Both cameras feature enhanced software optimizations and modes that improve photo quality and post-processing.Software-wise, the J5 (2017) ships with Android Nougat out of the box, bringing in new features and improvements to the user interface compared to the 2016 model's Marshmallow. Users can enjoy enhanced notifications, multitasking capabilities, and a smoother interface overall.Battery life has seen a positive bump as well, with a 3000mAh battery that supports fast charging, allowing users to recharge quickly without needing to plug in for long periods. This improvement ensures longer usage times without compromising performance.Overall, the Samsung Galaxy J5 (2017) is a well-rounded upgrade from the 2016 model, presenting advancements in design, performance, camera capabilities, and software that cater to the needs of modern smartphone users.
