Hi, Can anyone tell me why my internal memory shows 3gb of photos/video that I can't see? When I click on it all it shows is a few camera/screenshots. It's still there even after I unmount the external sd card. Would really like to get rid of this seemingly wasted memory.It's a rooted Galaxy Tab 2 7.0 p3113. Sorry of this topic has been covered before. Thanks in advance for any help provided.
