Want to update your Android tablet or phone to the latest Android operating system? It’s not that difficult, but there is a catch. Your device may not be able to upgrade. Since each Android device is different, that manufacturer has to prep a special version of the OS just for that device.
You’ll need to go to your device’s settings and look for a setting called About tablet or About phone.
If there’s an update available, you’ll see either an option for firmware update, system update, or software update.
You can also go to your tablet manufacturer’s website and check for updates. If it’s available, you can download it to your PC and then install.
