Periodically, Google updates its Android mobile operating system with a new iteration that includes additional features and security fixes. Each iteration is named after a food and follows an alphabetical sequence, for example, Android version 5 was named “Marshmallow,” followed by version 6, “Nougat.” Knowing what OS comes with your tablet is important. It can help you know how old the laptop is and if an update is supported. When comparing Galaxy tablets, check product pages to determine which Android version is included. If you’ve already got a Galaxy tablet, you can look up the Android version in the Settings app.
