I was a bit skeptical about getting this card because the official instructions for this phone only mention that the external memory is expandable UP TO 32gb. I did a bit of research before purchasing & many reported being able to use this card with the EVO 4G LTE. I can confirm that it works!At first, the phone won't recognize the card. YOU NEED TO FORMAT THE CARD WHEN YOU FIRST INSTALL IT! once you format the card, the phone will recognize it & you can write & read data with no issues.I got such a large card because of music. I wanted to add music in .wav format for better audio quality (or at least in mp3 320kbs). I'm very happy with this card!
