What an update does
Phone makers find and fix security holes all the time. An update closes them. If you skip updates, your phone keeps those holes, and bad websites and apps can use them.
Updates can also bring new protections, like better spam call and text filters.
Update an iPhone
- Plug in your phone and connect to Wi-Fi.
- Open Settings, then General, then Software Update.
- If an update is listed, tap Update Now or Install, and enter your passcode.
- To have this happen by itself, tap Automatic Updates on the same screen and turn the options on.
Update an Android phone
- On a Pixel and most Android phones: open Settings, then System, then Software updates, and follow the steps.
- On a Samsung Galaxy: open Settings, then Software update, then Download and install.
- Also open the Google Play Store, tap your profile picture, then Manage apps and device, and update your apps.
Real updates never come by text or pop up
Your phone's real updates only appear in the Settings app. A text, email, or website warning that says your phone is infected or needs an urgent update is a scam. Do not tap it and do not call any number it shows.
When your phone is too old
Every phone eventually stops getting updates. If Settings shows no updates for a long time and your apps start to stop working, ask your carrier or a family member whether your phone still gets security fixes. If it does not, it may be time to replace it.
