Due to background noise, I normally have my phone set to loud vibrate and ring. I rarely change it intentionally but it frequently changes itself to vibrate only. It happens at least once a day - sometimes more often. I am unaware of anything that I do to cause. It is extremely annoying and often causes me to miss calls. Thanks. Jim
