A little "trick" if somebody also finds it annoying to use this tiny screws every time when changing the battery:
I have removed the bottom screw and only using the one on the top of the backplate. When I must change my battery, I unscrew it only a little bit...so I can "rotate" the back plate and have access to the battery. Then only tighten the one screw again, and viola...
The backplate is fixed with this only one screw also...
Great idea! I will do that when I use it at home, thanx! I was gonna get a magnet change out next weekend, now I will try this for a while instead.
