Hi This is my first post as a noob. I just obtained my Galaxy S4 and trying to understand the firmware version installed on the phone. Following are the various details I could obtain using *#1234# code. AP: I9505XXUEMJ5 CP: I9505XXUEMJ5 CSC: I9505OJVEMJ5 I was looking around to map the various parts of the above codes to country/region/revision etc. But I am unable to map it due to the 'E' in the CSC. As I found out: OJV = Algeria, Egypt, Iran, Iraq, Kuwait, Morocco, Nigeria, Oman, Pakistan, Saudi Arabia,South Africa, Syria, Tunisia, Turkey MJ = 2013, October 5 = Version 5 Please help me figure out the various parts of the scheme. Is this a new numbering scheme introduced by Samsung? Thank You.
