Do you put the phone in your pants pocket? The chances of 3 Evo's having the same issue is very...very...very rare. It sounds more like something you are doing to the phone unententionally. If you put the phone in your pocket there is a chance you are flexing the phone/screen which is causing it to fail. You could also be in a climate sensitive area that is causing thing to expand and contract on the phone.
