I want to lock the volume on my Motorola E815, I have locked the ring style which is suppose to also lock the volume, I have learned that it only locks the volume button when the phone is closed and does not lock it when the phone is open. I find that I am accidently hitting the volume button with my finger when the phone is open and therefor turning down the ring volume by accident causing me to miss calls. Is there a way to lock the darn volume button when the phone is in the open position to prevent this?
