A new bug in Google Messages can cause your camera to turn on in the background, quickly draining your battery and heating up your device.
In the Google Messages app, there’s an easy way to quickly snap a photo and instantly attach it to a message and send it to a friend. In the view with images attached from your gallery, there’s also a live feed from your camera, and snaps can be taken instantly from that thumbnail view, or you can expand it for a better view.
In the latest update to the Google Messages app, as we discovered on one of our own devices and as reported on Reddit, a bug in the app occasionally caused this camera feed to appear even when it was not on screen (including when Messages while in the background) will also run. In our experience, as you might expect, this causes a lot of battery drain and heat.
With usage increasing for no apparent reason, we had to use Android 12’s camera and microphone privacy indicators to track down the issue. When something goes wrong, Android 12 devices will show that Google Messages is actively using your camera. The easiest way to fix the problem right now is to close the app from the Recents view.
More broadly, if you don’t use the Google Messages viewfinder, the easiest way to stop this issue entirely is to deny the app permission to use your phone’s camera. To do this on a Pixel phone, press and hold the Messages app icon in the launcher, then tap the info icon. This should take you to the Settings app, where you can tap Permissions to manage what Google Messages is allowed to do. From here, you need to tap on “Camera” and set the toggle to “Don’t Allow”.
