In fact, the built-in backup tools in Android and iOS now let you save almost everything you need to the cloud or to a computer, which wasn’t always the case in the past. On Android, head to Settings, then System, then Backup to see that the feature is working properly. On iOS, go to Settings, then tap your Apple ID name, then iCloud. You can also make a backup through iTunes by connecting your iPhone to your computer. Both of these backup tools take care of a lot of your phone’s contents, including photos and videos, call history, and browser settings.
