Current version is ZTE B2017G V1.0. B12
B12 is 7.1.1 Nougat ... that's the latest for this device. You can download the update from the Support portal and upgrade from your SD card.
@Enjay I am not sure what the the latest version of software is for devices in Nigeria. Your device may never have been updated to Nougat.
