The tweet showed how Ogdobber has used a razor blade to trim a mm off the edge of the power and volume control buttons to make them feel flush against the N7 case.
You might be wondering if there is a real practical point to this, other than aesthetics, but actually Ogdobber was experiencing a problem that I’ve also come across. The buttons are actually quite easy to press accidentally – particularly the on / off switch. This quick hack makes accidental switching far less likely.
Big thanks to ogdobber for sharing this and letting me use the picture.
