AT&T updates the Samsung Galaxy Note 4 to Android 5.0.1
Speaking of Quick Settings, the Android 5.0.1 update allows you to pull it down from any page and also adds Material Design, the 64-bit ART compiler, Project Volta, the new "Recent Apps" look, Lock Screen notifications and more. In addition, Find My Mobile and the Reactivation Lock are included along with stability improvements. The update to the Reactivation Lock forces someone with a stolen or lost device to sign into Google before the phone can be used, even if the handset is factory reset.
The size of the update is a massive 1.2GB and AT&T will only allow you to download it only via a Wi-Fi connection. While the carrier didn't mention it, we think it might be a good idea to have your battery recharged to at least 50% before you start the process. And yes, the update is being sent out on a staggered basis which means it might be a few days before it hits your Galaxy Note 4.
