I have an HTC Desire HD. I work in a noisy environment as well as ride a motorbike. I often don't hear or feel the vibrations when the phone rings. One of my previous phones had a function where it would ring once every 60 seconds until I attended to the message on my phone.
Is there a way that will provide this service?
Another issue is that sometimes the volume gets reduced. I must accidentally turn it off when I put the phone on my belt clip. One day I had 20 missed calls when checked because the device didn't ring for those calls.
