Could not figure out why this card crashed multiple times in my Samsung Galaxy SIII, and demanded a reformatting. Then after 5hrs of calls to Sprint & Samsung I got a guy who reads factory stuff!Samsung Galaxy SIII is a Class 4 & Class 6 supported Motherboard, with Qualcomm processor. The Sprint stores only sell Class 4 memory, and there is a reason that Camera memory~Class 10 is not sold there, the board, just like in a PC, has to support the data stream. It does not!If you have an Android Phone you better make sure the motherboard supports it! Even Samsung's USA website does not tell you the board supported memory! They won't, and don't tell who the board manufacturer is in this Galaxy SIII phone. I asked at the Texas Samsung advanced tech support center after 1hr on hold, and they had no specs to even share. They don't get it!PASS IF YOU HAVE A CELL PHONE, UNLESS YOU GET IT IN WRITING FROM THE MOTHERBOARD MANUFACTURER OF YOUR PHONE. I went through this same stuff building custom PC's with Intel motherboards. Memory has to be built to run on this board, at this speed, with this processor, or it will not work properly, and will crash, and lose data.
