Hi all! I bought a new nokia lumia 820 back in march or something, before that i had a LG Optimus 2X P990. I bought the 820 without a SD Card, but the O2X has one that fits. I put it in the lumia 820, and it worked partly. The phone says theres an error with the SD card, the phone boots slower, it takes longer to capture a photo, it moves to the left later, and so on. I thought that it may have had something to do with the filesystem? Please help me, I don't want to buy a new one Thanks
