Adding devices to Google Play allows users to access their purchased apps, movies, TV shows, and books across multiple devices. To add a device, open the Google Play Store app on the new device and sign in with the same Google account that is used on the primary device. Once signed in, the new device will be added to the list of authorized devices in the Google Play Store account.
There are several benefits to adding devices to Google Play. First, it allows users to access their purchased content on any of their devices. This is especially useful for users who have multiple devices, such as a smartphone, tablet, and laptop. Second, adding devices to Google Play can help users to keep track of their purchased content. The Google Play Store app on each device will display a list of all of the apps, movies, TV shows, and books that have been purchased on that account. This can help users to avoid accidentally purchasing the same content multiple times.
