Okay, so since July, my MicroSD card would only go into the slot half way - even pushing hard on it. Yes, it was oriented correctly. Didn't seem right, but images were being recorded and I had taken the card in and out quite a lot of times with the same half way issue. Figured that's just the way it is. Well, just after I posted this, the card finally fit into the slot perfectly and with no effort at all. It actually slipped in all the way with the spring-load action. I'm not sure what had been blocking it, but now it seems to be working correctly. Weird.
