Updated yesterday to fix the Stagefright bug on an SGH-I337M Samsung Galaxy S4, which I've only got for 1 month (new). Basically, the rear camera only shows a black screen, with a pop-up stating "Updating camera firmware. Please wait..." Cannot take pictures, and after a while, the camera app stops and the home screen is shown.
I dialed *#34971539# to check the firmware version, and got the following:
* rear camera Cam FW Ver: null
* rear camera Phone FW Ver: O13F0LAGI02
* front camera Cam FW Ver: S5K6B2YX
* front camera Phone FW Ver: S5K6B2YX
The "null" value looks weird, any idea how to fix this camera firmware issue?
