Keep protection current.
Keep protection current. Make sense of device warnings.
Phones, tablets and computers. Update availability depends on the device and vendor support.
01 / Answer
What you need to know.
Software updates can fix security weaknesses. Use the updater built into your device or app, rather than trusting an unexpected pop-up that tells you to download a fix.
02 / Check
Look before you act.
- Open the device’s own Settings and find Software Update or System Update. Check whether an update is waiting.
- Check app updates through the official app store or the app’s built-in updater.
03 / Do
Make one useful change.
- Save your work and follow the device’s update instructions. Connect to power when requested.
- Enable automatic updates where available. On a managed work device, follow your organization’s update process.
04 / Verify
Check the change stuck.
- After any required restart, return to the update screen and check the status again.
- If the device cannot receive supported updates, check the manufacturer’s support information and plan how to replace or retire it.
