Nokia Lumia 900 AT&T Performance and Software

Performance and Software

Powered by a Qualcomm APQ8055 Snapdragon S2 chipset with a 1.4 GHz Scorpion CPU and an Adreno 205 GPU, the Lumia 900 was reasonably robust for its period. It came with 512MB RAM and 16GB of internal storage, albeit lacking a card slot for expansion. The Windows Phone 7.5 Mango operating system offered fluid and intuitive navigation, featuring live tiles and integration with Microsoft services. However, it lagged behind its Android and iOS counterparts in terms of app availability and lifecycle support.
