The latest update to the AT&T version of the Samsung GALAXY Note II leaves the device at Android 4.1.2
The update has to be downloaded over Wi-Fi and those who have installed it report that their phablet runs faster with apps completely updated and zipping along. One AT&T Samsung GALAXY Note II user was getting some rather poor Wi-Fi speeds of 3 to 4Mbps down and 1Mbps up. After the update, he reported getting speeds over Wi-Fi of 31Mbps down and 5Mbps up.
Additionally, the update is said to include security improvements to the lock screen, improvements to voicemail and enhancements to ISIS. The latter is the mobile payment service founded by T-Mobile, Verizon and AT&T, which works on certain Android models that support NFC.
