I have a K770i and it has been working fine until today when the camera says "Another application is running. Close it, then start the camera." I haven't played with any of the software so it must be a hardware issue. It appears both cameras do not work as I tried video calling and the front camera won't work either. I've searched through the forum but was just wanting to get a bit more advice.
Can anyone give me some pointers on what to do to fix it? thanks
