Hi all, I got my new Galaxy Ace this morning and it's brilliant so far, but there seems to be an issue with my SD Card, possibly a slot issue I'm not sure, but my SD card doesn't lock into the slot? It gets to a certain point and can't go any further; I can push it down further but there's no catch where the card can be kept in place, so I have to force the SD slot door thing down for a few seconds for the card to stay in place, but any minor touch on the door cause the door to open slightly and the card pops out again. Is this normal for the slot, or am I doing something wrong? Thank you!
