Google has a clever system that alerts you over dodgy apps that you should delete. If you're an Android phone owner, it's important to make sure you're using it correctly.

Watch out for Google Play Protect alerts – they help to keep your Android phone safe

The warning works via Google Play Protect, a feature designed to scan apps and warn you if something is wrong. "Your device comes with a built-in, free security tool: Google Play Protect," Google explained. "Google Play Protect analyzes potentially harmful apps before you download them. And Android regularly scans your apps for malware, prompting you to uninstall any bad apps."

If Google Play Protect is switched on, you may see a warning that says: "Play Protect warning"

It may say something like "This app can damage your device, add hidden charges to your mobile bill, or steal your personal information." If you see one of these warnings (or any other) from Google Play Protect, consider deleting – or avoid installing – the app in question. You can also check your apps and games list to scan apps for problems.

How to use Google Play Protect

Google Play Protect is usually on by default. But you can check that it's on – and make sure you didn't ever turn it off accidentally – very easily. Just open the Google Play Store app and tap on your profile icon in the top-right. Now tap on Play Protect and then choose Settings. Then simply make sure that Scan Apps With Play Protect is switched on. You can also set it up to automatically scan unknown apps that were installed from outside of the Google Play Store. Just go back into the Play Protect settings and turn Improve Harmful App Detection on.

It's also important to check how an app might be using your data before you even download it

Google noted: "Before you install an app, you can view details from the developer about how they handle your data. To do so, go to the Data safety section on an app’s detail page. Under ‘Data safety,’ you’ll find a summary of the app’s data safety practices. For more detail, tap ‘See details’. This way, you can make more informed decisions about what apps you use and download with confidence."
