Samsung launched the Android update Nougat to the new generation of the large A7 phone launched earlier this year and was carrying Android Marshalmu, although many of the phones launched in the same period came directly Nougat.
The update comes in more than 1300 MB so it will take some time to download it according to your download speed. It is always recommended that you have at least 50% battery charge.
The Android Nougat update offers improvements in the user interface and new features such as multiple accounts for chat and social networks so that they can easily navigate between multiple accounts for the same application, as well as improve the permanent operating position of the screen, and finally improve storage space for applications and accelerate system upgrade and application installation.
As usual, the update will take up to months to reach all over the world, especially in the Arab region, but you can always lose access to settings.
