I connected it to my galaxy S4, but every now and then (once or twice a week) it will eject from my phone and the phone will need to re read the card. It's not a big issue, but when it happens you may need to wait like 4 min for your files.It happens a lot less now that i dont use the powersaving funtion. Something about the powersaving on the phone seems to not deliver enough power to the card.
