Has anyone out there noticed that on their bolt the volume rocker is a little more sunken in on the plus side? I noticed this a few days back, where the plus side also sticks at times yet most of the time still turns up the volume. Then last night I discover that my lock/power button really sticks, and is almost totally flush with the surface of the phone. Then at times when I press on it nothing registers. If this keeps up I may have to swap it.
