Can someone else with this phone confirm something or is it just my device? I've had the leather case on it since day 1, and volume down has always been harder to push than volume up. So I took it out of the case for the first time this morning and noticed the volume down button has a noticeably softer click and is quieter when depressing than volume up. This was not an issue with my 5S at all, all buttons felt/sounded exactly the same. I'd like to ask you guys if your buttons are different or consistently the same.
