Performance
Under the hood, the device runs on Android 7.0 Nougat, supported by the Mediatek MT6737 chipset and a quad-core Cortex-A53 CPU clocked at 1.3 GHz. The Mali-T720MP2 GPU handles graphic tasks, although its performance is better suited for basic apps and light gaming. With 3GB of RAM and 32GB of internal storage, expandable via a microSDXC card using a shared SIM slot, the Z90 offers adequate multitasking capacity and storage space for essential apps and media.
