It appears as if my Evo is erasing files from the Sandisk card that was pre-installed. For instance, I'll copy over wallpapers from my laptop last night & this morning, only half appear in that folder in the gallery. I'm wondering if this issue is somehow attributed to the update that was supposed to fix the "SD card" issue. I might just try re-formatting my card & see if that solves it. Has anyone else experienced this issue?
