EVO 3D. Several hours after I take pictures, they are replaced in the gallery by a symbol which is a triangle with an exclamation point through it. If I load these files to my PC, they appear as JPG files, but they cannot be opened with any application.

I have a 32GB micro SD card in the phone:. Is there a limit on the size of a micro SD card which can by used in this phone ? Do I possibly have a bad micro SD card ?
