Samsung flagship could be updated to Android 4.1 Jelly Bean within 4-6 weeks
The site states that ‘there is no date planned yet but it could be around August/September’. Even if the update does arrive in September, it would make it one of the fastest upgrades rolled out by an OEM.
However, experience would tell us to expect the later date of the two, especially given the time that manufacturers have taken to roll out Android updates in the past. SamMobile also speculates that updates for the Galaxy Note, S2 and Tab 7.7 could follow shortly after that of the S3.
With Google announcing the PDK at Google I/O in order to assist with OEM upgrades, hopefully this will be the beginning of quicker upgrades for non-Nexus handsets.
