Green dot on your Redmi? Check camera and microphone use

Check your software and identify the app

Google's instructions below cover Android 12 and later, with some steps varying by device. Use them on a Redmi that offers the matching indicator and controls; this is not a promise that every MIUI or HyperOS version has identical menus.

1. While the indicator is visible, swipe down and tap it. Google's guide says the first tap identifies the app or service using the camera or microphone.

2. Tap again to manage permissions where that control is available. Google notes that swiping down may not work on every device.

3. Compare the named app with what you were doing. I'd expect to investigate differently if I had just started a video call than if I could not account for the app at all. Note the name and time before changing anything.

Review one permission at a time

Google's general app route is Settings, Apps, the chosen app, then Permissions. Redmi menu labels can differ, so search Settings for permissions if the route does not match your phone. Check the exact model's Xiaomi support information if you still cannot find it.

Choose the relevant camera or microphone permission and review the choices offered. Android may provide options such as access only while using the app, asking every time, or not allowing access. The available choices depend on the permission and software.

I'd give access according to the feature I actually want to use. If I change a setting, I would reopen that feature and check the result. If it needs access, I can return to the same permission screen and reconsider the choice rather than grant everything at once.

Look back at recent activity where supported

If your phone offers Privacy dashboard, it can show which apps used a permission and when. Google's general route is Settings, Security and Privacy or Privacy, then Privacy dashboard; sometimes Privacy must be opened again. Select Camera or Microphone to review the available history.

Check the time window displayed on your own screen. A recent-access history is useful context, not a complete explanation of what an app did with the information.

If a call or recording stops working

Google advises checking that camera or microphone access has not been blocked when those features fail. If you changed access during this check, review that change first. Record the app, model and software version if you need help from Xiaomi or the app developer.

For the broader first-day checks, my new Redmi setup guide covers updates, account recovery and backups. I would keep a permission review focused on the particular feature I need, rather than turn every prompt into an automatic yes.
