AT&T already announced that today would mark the initial rollout of an update for Galaxy Note II users, bringing the highly touted multi-window feature to eager multitaskers. Thankfully, things seem to be right on schedule as a large number of users are reporting a hefty update waiting to be downloaded.
Measuring in at 178MB, the update appears to be hitting devices in phases, so if you don’t see it straight away, you may have luck checking for the update manually by heading to Settings > About Phone > Software Updates. We’ll see you on the other side.
