Performance
Under the hood, the Lava Z40 runs on the Android 8.1 Oreo (Go edition) operating system, which is optimized for entry-level devices. This ensures smoother performance despite its modest hardware, as the OS is configured to function efficiently with the device's 1GB of RAM and 8GB of internal storage. The handset is powered by a Unisoc SC9832E chipset, coupled with a 1.4 GHz quad-core CPU and a Mali GPU, providing just enough power to manage basic tasks and applications with ease. There is also a microSDXC card slot for expanding storage, which is essential given the limited internal memory.
