Samsung Galaxy A15 4G

The Samsung Galaxy A15 4G is a budget phone that brings significant upgrades to the A10 series. The device boasts an AMOLED screen with a 6.5-inch display and a fast 90Hz refresh rate, making it sharper and contrasty than its predecessor. However, the presence of thick bezels and lack of HDR video support reminds you that this is a budget device. The phone's design is standard for Samsung budget phones, with separate camera rings and a flat plastic back. The fingerprint reader is built into the power key, and the interface runs on Android 14 with Samsung's One UI 6. Despite its budget nature, the phone gets three major Android updates and four years of security patches. Under the hood, the Galaxy A15 4G uses the MediaTek Helio G99 chipset, which provides solid enough performance for everyday tasks. The phone has a 5,000mAh battery with excellent battery life, earning an active use score of 15 hours and 28 minutes. However, the camera setup is familiar, with a 50-megapixel main camera that produces average photos in detail but excels in color rendition. The Galaxy A15 4G also has a single bottom-firing speaker and lacks IP-rated ingress protection. While it's not perfect, this phone is still a solid package for its price, making it easy to recommend if you're looking for something within your budget.
