I have a new Sandisk micro SD 16GB which overheats within minutes of inserting it into my new Samsung GT S7392.it doesn't get warm it gets hotplate hot . Enough to give me a blister when removing it . On re insertion it heats up within seconds .left unnoticed it would possibly catch fire . Could someone kindly advise on this . Is it the card or phone problem . Phone is under warranty from fortress but I want a heads up before I take it back .I was astonished a memory card could heat up to that degree so fast .
