With all the apps we usually have running on our phones, it’s a constant concern of whether the battery will last all day, and that doesn’t help when apps crash and run power-hungry functions in the background. According 9to5Google, a recent bug in the Google Messages app on Android phones it left the camera running in the background, a great way to heat up your phone and drain the battery.
The Google Messages app allows you to take a photo directly from the app and attach it to a chat message. According to the article in 9to5Google, the camera app kept running occasionally, even when you didn’t have it on the screen. (This problem also reported to have happened with a Pixel 6 Pro in a Reddit group).
We were unable to reproduce the issue. However, if you find that your phone is unusually hot or the battery is draining very quickly, it might not hurt to make sure your camera isn’t working yet, or simply slide the Messages app out of the Recents view, which will cause the application to close. You can also deny Messages permission to use your camera entirely by going to Settings > Apps > Messages > Permissions > Camera and selecting “Don’t allow.”
However, that may not be necessary. According to Scott Westover, Communications Manager at Google, the bug has been identified and the fix is currently being rolled out to users.
