I have had this Evo 4G for close to a year (in June), never had any issues with it, until now. The camera/camcorder won't work. I tap the camera/camcorder icon(s) and it looks like its about to open, but just goes to a black screen. No icons, no menues, no image from the lense. Just a black blank screen. Tapping "menue" does nothing. Anyone have this issue? I use my camera phone quite a bit (more than my camera). Any help would be appreciated. I have not installed any new apps. Camera worked fine just the other day, noticed it not working this weekend.
try going into your applications (menu-settings-applications-all applications) and chose the camera app..then clear its data and cache if it has any. this will not remove any of your pictures sinse theyre saved on your sd card anyways. might as well do it to your video camera app as well. if this doesnt work then i recomend going into the sprint repair store as lilgeekygirl stated above.
