There is another recent thread addressing this same issue, however the OP said his situation resolved itself and I am afraid if I just post there that my question will be overlooked.
BUT
My camera will not save my pictures. I take the picture, the camera behaves normally and animates the picture shrinking into the corner. However when I touch on the picture in the corner, or try to look at the pictures in the gallery, there is nothing but a grey box, much like a .jpg icon. When I go to "Picture Info" it says that it is 0.00B.
Also, there are a few of my existing pictures that are visible in the Gallery, but when I tap on them, they flash as the picture quickly, but then default to the same grey box.
Thirdly, A few times now, the camera itself simply won't open, including through an app that has worked very well for me since I got the phone. It crashes and asks for a "Force Close." This problem resolves if I reboot the phone, but the pictures still do not get saved.
According to my data page, there are almost 2 Gb of space still available on the SD card.
As with the other thread, I can still take and save Movies, but not still pictures.
And just for full disclosure, I am also having an issue where when I try to answer the phone, everything on the touch screen happens correctly, however I cannot hear the call, and the person cannot hear me. It resolves itself when I reboot the phone, but it is very annoying.
Any thoughts?
