Re: S4 Photo problem
Well... First a few questions...
Is the phone running stock firmware or a custom Rom?
Is the phone saving the pics to external memory card.... Or internal phone memory?
Did this start happening after a modification of some type?
Can you record video?
Now I will try guessing...
If your pics go to external memory card try switching to phone internal memory, if that works... You might have a bad external memory card.(or card reader)
If the phone has a custom Rom... Try flashing back to a stock firmware.
If the phone has stock firmware and you are saving the pics to internal memory... And still have the same problem im afraid its the hardware camera module itself
Also... You might want to backup all your data /apps /contacts (externally) and try a factory reset from recovery mode.
