Broke My Volume Buttons I'm on the Nexus 6P running Android 7.1.1. After Talkback was automatically installed  my volume buttons no longer worked. Screenshots worked fine (using the volume down button) and the volume changes when the screen is completely off but when the screen is on nothing happened. Not even the volume menu appeared when the buttons were pressed. The issue was fixed immediately upon uninstalling Talkback without any reboots or other updates.
