The new update, which bears version number:G925FXXU5EQBG, is huge in size. Samsung device owners are advised to free up the device's internal storage (about 1.5GB) and also make sure to back-up their phones, to avoid any loss of data. Sometimes, if the software upgrade faces any interruption, it might wipe out the memory.

How to install Android Nougat update on Samsung Galaxy S6 and the S6 edge:

1. Once you get the update notification on the phone's screen, select "Yes, I'm in."

2. After the software is downloaded, select "Install now."

3. After the software is installed, your phone will re-start automatically.

4. Your phone is now updated.

Since the OTA roll-out process is being carried out in phases, it will take several days to reach all the corners of the country.

Until then, device owners can check for updates manually by going to Settings >> About Phone >> System Updates >> check for the new firmware.
