Thanks for the heads up. I'll try my SD cards tonight and see how they do. My phone has updated 3 times and so far no fix. Maybe this is the one. I am not going to get my hopes up though. ... View more

The phone lock up is irritating but losing picture opportunities is the most frustrating as you can't recreate those.
