Hi All!
I am not sure this topic was not discussed so if I am double-posting - sorry!
Anyway I was informed someone expects problem with camera after update to 4.1.2.
The reason is the firmware contains updated driver which is not pre-installed in the phone because the firmware is actually a dump.
I would like to explain the way I performed to solve the problem (now I have GT-i9300 with 4.1.2 and working stock Camera (both video/photo) and other camera applications also).
First of all: make a Nandroid backup! I have tested all the steps but I cannot guaranty everything will work properly in your case.
Second - I can help with GT-i9300 only. If you have other device - sorry. Maybe this receipt works - maybe not, I don't know.
1. Please dial in stock dialer the following: *#34971539#
2. In menu please choose Phone/CAM FW Ver Check
We need to know your two parameters: Cam FW Ver and Phone FW Ver.
Cam FW Ver is a version of driver installed in your phone. Phone FW Ver is a version which comes with a firmware. Usually firmware's one is newer. In my case it was
3. You have to download newer driver. In my example I had to download ZDFI02 driver - and I believe everybody will have the same issue because this is the driver which comes with leaked 4.1.2. In other way I suspect you have mixed up something to make Camera working - I suggest to re-burn the firmware again. Anyway - you are free to test.
Be careful! There are other camera vendors exists - and it is easy to detect by first two letters of driver version (in our case it is ZD). If you have other vendor - please download appropriate driver.
After you have download the archive you have to unpack the file named "SlimISP.bin" on your sdcard (internal one).
Then dial *#34971539# once again and choose Phone to CAM FW Write (Rear) (if you have unpacked the file properly - this button will become active). Flashing will take about 20-30 seconds - please be patient.
After flashing finishes exit the Camera Firmware menu and enter it once again (*#34971539#). Choose Phone/CAM FW Ver Check
Check again above-mentioned two parameters: Cam FW Ver and Phone FW Ver. If you are lucky enough they will be equal and the process completed successfully.
