ZTE Axon 7 Mini gets Android 7.1.1 and T-Mobile Wi-Fi calling
As the Axon 7 Mini is jumping straight from Android Marshmallow to 7.1.1, owners of the device will have access to some key new features. Some of them include split-screen multitasking, dual-language support, updated emojis, as well as performance and battery life optimizations. Additionally, support for T-Mobile's Wi-Fi calling is also thrown in the mix, allowing users of the carrier to talk and text without using up mobile data.
You can install the latest patch by going to Settings -> System Update. As always, make sure that your phone is charged and connected to a Wi-Fi network before proceeding.
