The update weighs around 1.09GB in size. It includes all the basic goodies of Android 7.0 Nougat i.e. the split-screen multitasking, customizable quick settings, improved Google keyboard, enhanced notifications and recent applications window, improved Doze mode. Along with all these features the update also includes the Android Security Patch for the month of February 2017.
Keeping in mind the update file is a large one. We recommends you to download it over the WiFi network to avoid the data charges. Make sure the phones battery is fully charged at the time of install.
