If you own a Moto G5 Plus in South America you should have received the over-the-air update notification for November 1 Android security update. We will let you know once the update is out for other countries. Stay tuned to our Facebook and Twitter page to get the first News.
Motorola’s instructions explain that for a successful installation, the battery in your phone should be at least 50% charged and your device should be connected to a Wi-Fi network or LTE.
you haven't got the notification of this new software update yet, Just go to Settings - About Phone - Software updates, and It will automatically start downloading the latest update. The update will take around 10-15 minutes to get Installed on your device.
