Performance and Software
Under the hood, the Lumia 640 LTE is powered by the Qualcomm Snapdragon 400 chipset featuring a quad-core 1.2 GHz Cortex-A7 CPU and an Adreno 305 GPU. While these specifications may seem modest by modern standards, they were adequate for handling the Windows Phone 8.1 operating system, which is upgradable to Windows 10 Mobile. The 1GB RAM ensures smooth operations for basic multitasking and running applications, though demanding tasks may cause occasional slowdowns.
