Still, having something is definitely a whole lot better than nothing, and AT&T subscribers who are still using the Samsung Galaxy S5 will have a good time looking forward to this particular update. With Android 5.1.1 Lollipop in tow, this particular update will also be accompanied by Android for Work, a handful of security updates in addition to fixing the Ultra Power Saving Mode for phones via on-device encryption.
Bear in mind that this an over-the-air (OTA) rollout, so if it has not reached your device just yet, fret not – the notification should hit your smartphone sooner rather than later. Those who are pro-active and would prefer to take things into their own hands can always perform a manual check by heading to Settings > About device > Software update. The entire update is best downloaded via Wi-Fi as it weighs in at 610MB thereabouts. [AT&T Page]
