Just recently – 2 days past – my camera app stopped working. As of this post, its not even turning on. Before, it merely showed a black screen with the main shutter button not responding. This is for all camera related apps – not just the stock Apple one. Before this occurred, there was no trauma either software-wise nor hardware-wise so its quite strange. Because I’m on 7.0.4, I can’t restore this iphone. What I’ve done is: 1) Reset all settings through Settings App 2) Use iLEX R.A.T to reset to stock iOS w/o losing jailbreak 3) Used SemiRestore7 to “semi-restore” the iPhone. None of these options worked. I’m including a video on YouTube of the direct issue occurring whilst opening the Camera App as well as the list of Cydia Apps installed on my iPhone. Hopefully this will be enough to troubleshoot mine (and others’) issues in regards to this strange flaw. VIDEO HERE UPDATE: In SAFE MODE I'm able to access the front camera (STOCK APP) but the back camera is still a no go. It just freezes and stalls. No response and I have to force quit the app.
