Update to Moto G5 Plus improves the audio recorded while capturing video
The new software version is NPN25.137-33, and it weighs in at 280.7MB. Once the notification arrives, users should make sure that they are connected to a Wi-Fi network before starting the updating process. In addition, the battery should be fully charged before the downloading begins. It should take about 10-minutes for the update to be fully installed on the Moto G5 Plus.
Since the update is being disseminated OTA, it might take a few days before it hits your phone. You can try to manually update the handset by going to Settings > About Phone > Software updates.
