I think its safer to just put it away. Its not so important.
Ive been using the mountek ngrove snap http://www.amazon.com/Mountek-nGroove-Magnetic-Vehicle-Devices/dp/B00E9L0HGI for the past few months, its awesome. When i had an iphone i removed the back cover (its only 2 screws) and put the thin metal plate inside the phone, now with my galaxy i placed the metal plate between the 2 layers of my phone case.
