Samsung has confirmed that the Android 5.0 Lollipop update will be rolling out to Galaxy Note 3 owners in the United States, particularly among T-Mobile customers. Sprint is expected to release the update soon.

According to the South Korean company’s software upgrade page for the phablet, the Lollipop update has already been released since March 4. T-Mobile became the first U.S. mobile carrier to provide such upgrade to its customers.

Other U.S. carriers have not yet released the official Lollipop update for the Galaxy Note 3, while other countries have already begun bringing the new Android experience to the owners of such device. These include the U.K., Germany, Austria, Hungary, Czech Republic, Switzerland and Romania.

Another major mobile carrier in the U.S., Sprint, recently shared a post on their website that showed an internal document with details regarding an upcoming Lollipop update for Galaxy Note 3 users.

Meanwhile, there has not been any information from fellow mobile carriers Verizon and AT&T concerning updates for the said phablet.

For the Galaxy Note 3, a number of improvements can be expected when receiving the Lollipop update. These include enhanced Wi-Fi calling experience as well as resolved Wi-Fi calling one-way audio and resolved IPv6 email setup, as specified in the Samsung website.

The OS upgrade will also bring about significant performance and improvements in terms of battery life, which can mostly be attributed to Google’s decision in using the ART runtime by default for Android 5.0 and above.

Although it was speculated that the U.S. will get to see an update for the newer Note 4 first, the Note 3 users had been the first group of Samsung phablet owners to obtain the Lollipop upgrade.

Nonetheless, Sprint has just confirmed that it will follow with the update for the Galaxy Note 4

In addition, the new Android 5.0 update has also been released to an international Galaxy S4 variant, the GT-I90505. For the U.S. release of the Lollipop update among Galaxy S4 owners, official announcements from mobile carriers are yet to be made.
