Editorial note

The Samsung Galaxy J4 stands out with its 5.5-inch Super AMOLED display, offering exceptional picture quality with vibrant colors and high contrast, ideal for enjoying your multimedia content. Performance is generally smooth thanks to a 1.4 GHz quad-core processor paired with 2 GB of RAM. However, this RAM capacity may limit the use of multiple applications simultaneously, leading to slowdowns during more demanding tasks. The 3000 mAh battery life is a strong point, allowing for prolonged use without the need for frequent recharging, which is appreciated for daily use. In terms of design, the Galaxy J4 has a modern and sleek look, although the Micro-USB connector, while functional, seems outdated compared to newer USB-C standards. Camera features are satisfactory, with a 13 MP resolution on the back that allows for quality image capture. However, the 5 MP front camera may not suit selfie enthusiasts looking for superior image quality. Additionally, the lack of contactless payment functionality limits convenient payment options for modern users. In summary, the Samsung Galaxy J4 offers a fair price-to-quality ratio, but the screen resolution of 720 x 1280 pixels is lower than that of many competitors, affecting display quality for high-definition content. Support documents, such as the user manual and safety instructions, provide valuable assistance for users.
