WHY can I not keep an uncorrupted SD card in my Edge?


AC Question

I have done all recommended steps, after purchasing 3 different brands of SD cards, including a Samsung, I cannot keep them from corrupting! I even invested in a flash drive that I can plug directly into the phone, so that I don't have to keep taking the card out to download to my computer. I have mounted/unmounted each and every time, and formatted disk in the phone!!!

HELP!! I take hundreds of pics and have lost hundreds of pics in the process of all of this hassle! What else can I do? I cannot afford the purchase of new SD cards, and am heartbroken at the loss of my pics!

Thanks, in advance, for ANY ideas!
