Has anyone else noticed this on their Epic? Neither of my friends devices have the feeling when opened or closed. The best I can describe it is as though the spring isn't damped enough and it takes a second or two to stop vibrating. I can feel the spring gradually stop. Its nowhere near as strong as the vib function on the phone but its enough that my buddy asked about it the first time he opened mine. After trying both his and his wifes it is definitely only on mine. I'm thinking I should go trade it out now rather tan have the slider weaken or break down the line and be on the hook for repairs.
