My HTC One X has started to make a sound everytime I pull the ring to unlock it. Sometimes it seems to get a lag and makes this sound three times in a row. I have gone through all the settings, but have yet to find a setting that allows me to turn this sound off.
In Settings > Sound > the 'Screen lock sound' is unticked. When I tick this to see the change, it makes an additional (different) sound for when I lock my HTC and unlock it.
I don't understand why this sound has suddenly appeared, I don't remember changing any sound settings since it started doing this.
Many thanks and kind regards,
