Performance
Under the hood, the QMobile Noir Z7 is powered by a Mediatek MT6592 chipset with an octa-core 1.7 GHz Cortex-A7 CPU, paired with a Mali-450MP4 GPU. While the 1GB of RAM might struggle with multitasking in contemporary contexts, this configuration was satisfactory for handling basic applications and moderate gaming in 2015. The device runs on Android 4.4.2 KitKat, an OS that was both stable and user-friendly at launch. However, the lack of system updates may limit its functionality over time.
