Samsung and Spain’s carriers Vodafone and Orange recently rolling out the latest Android 4.1.2 Jelly Bean update for Samsung Galaxy S3 (GT-I9300) with build number “I9300XXEMR7”. Maybe some of you is aware if this version posses the higher changes since the build ‘MR’ series is now something new to everyone. Well, if you will take a look closer using a simple analysis of firmware build chagelist, the “I9300XXEMR7” is not a higher build than the recent releases “I9300XXEMC2” for unbranded Galaxy S3 variants.
Build | Chagelist
I9300XXEMC2 = 1042335
I9300XXEMR7 = 1028785
Aside from the “EMC2” which is the latest build is also posses with the latest changes. So, for those who got the unbranded Samsung Galaxy S3, I suggest not to install this firmware. This is a carrier specific firmware build and works best for Spain’s Vodafone and Orange Galaxy S3 users only.
