Google Confirms Android Bug in Select to Speak That Breaks Volume Controls and Camera Shots

Google urges affected users to disable Select to Speak pending a system update, with no timeline provided.

Overview

The malfunction occurs when the Select to Speak accessibility service is turned on, causing hardware keys to behave incorrectly.
Volume presses change the Accessibility channel instead of Media, affecting music and video playback control.
Using a volume key in the Camera app does not capture photos as expected.
Google acknowledged the issue on its support forum through community manager Aadil Shaikh and said a fix is in development.
As a temporary workaround, users can disable Select to Speak via Settings > Accessibility > Select to Speak, and Google has not specified affected versions or a release date for the patch.
