Has anyone else had this? After watching video in the videos app, the lock/unlock click sound is super loud. Even with the sound turned all the way down. The only way I can get it back to normal is to play some music or something from Youtube. What I realized is that the sound of the lock/unlock click matches the volume level of the videos app. However, even after quitting the videos app, the sound doesn't go back to match the general volume level unless I use the speaker for something else.
