I have the Droid 2 and have problems saving pictures. Especially if the phone is running slow, it wont save pictures taken by the camera. When I take the picture, I see the thumbnail in the bottom left of the screen, but it does not show up in the gallery. I tried taking a handful of pictures and none of them show up, only the pictures from a few days ago.
Frequently when this happens, the gallery takes forever to load, or doesnt load at all. It will slowly fill the gallery with blank thumbnails, not the actual thumbnails.
I have sd rescan, but it doesnt seem to be an issue of refreshing the images, but a problem loading them altogether.
I have a 16 gb micro sd card in my D2 and have plenty of free space available. I am going to try removing a lot from the sd card and see if that helps speed anything up.
