The Nokia Lumia 630 showcases a vibrant design with a 4.5-inch display, powered by Windows Phone 8.1, featuring new functionalities like action center and Cortana (limited to the US). It has a 5MP camera suitable for daytime use but lacks a front camera and sufficient RAM for heavy multitasking. Despite hardware limitations, it offers decent battery life and a range of preloaded apps, making it a strong contender in the budget smartphone market.
