How to Update Your Android Tablet System
Every so often, a new version of the Android tablet’s operating system becomes available. It’s an Android update because Android is the name of the operating system, not because the Android tablet thinks that it’s some type of robot.
When an automatic update occurs, you see an alert or a message indicating that a system upgrade is available.
You usually have three options:
My advice is to choose Install Now and get it over with — unless you’re doing something urgent, in which case you can put off the update until later by choosing Install Later.
If possible, connect the Android tablet to a power source during an update.
Some updates may simply present themselves with an Install and Restart button.
You can manually check for updates: In the Settings app, choose About Tablet (or About Device) and then choose System Updates. When the system is up-to-date, the screen tells you so. Otherwise, you find directions for updating the Android operating system.
Touching the Check Now button isn’t magic. If an update is available, the tablet lets you know.
Non-Android system updates might also be issued. For example, the tablet’s manufacturer may send out an update to the Android tablet’s guts. This type of update is often called a firmware update. As with Android updates, you should accept all firmware updates.
