Samsung Galaxy Note 4-19

AT&T is rolling out its latest software update for the Samsung Galaxy Note 4, adding HD Voice in addition to a number of updated apps and performance improvements. This will almost certainly be the handset's final KitKat release before it's graced by Android 5.0 Lollipop.

The new firmware sports build number "N910AUCU1BNK3," Droid-Life reports, and its highlight is the introducing of HD Voice. This routes your calls through AT&T's 4G LTE network to deliver "crystal clear conversations," while allowing you to use 4G data for web browsing simultaneously.

There is a caveat, however. HD Voice coverage is only available in select areas throughout the United States, and both you and the person you're calling must have the feature enabled for it to work.

This release will also install some third-party applications (or bloatware) on your Galaxy Note 4 whether you like it or not, but most of them are popular apps you may already be using anyway. Those included are Amazon, Evernote, and Softcard, the digital wallet service that was formerly named ISIS.

AT&T also promises "miscellaneous improvements," so you may notice better stability and enhanced performance after updating. If you haven't already received an update notification on your Galaxy Note 4, check the software update section inside the Settings app.
