I just recently got the Platinum Series 3400 mah extended battery for my Evo V 4G. I had a feeling that the extended back cover that came with it wouldn't be the best of quality because many reviewers stated that the power button wouldn't work well. To my surprise, it wasn't the power button that gave me issues, it was the Volume Up Button. The volume down button works everytime and gives a decent amount of feedback, but the volume up button is without feedback and most of the time hit or miss. I am not sure what to do in this situation. Any advice on things that I could do to remedy this?
