It’s refreshing to see a new name in the midst of all the Galaxy S9 and S9 Plus Android Pie rollouts. Xfinity had the honour of being the first US-based carrier to update their devices, followed by Verizon and then most recently; Sprint. AT&T joins that list today as several users confirmed receiving the Android Pie update on their Galaxy S9+ on Reddit.

Samsung Galaxy Note 9 users on AT&T have a surprise in store for them too. Today, the carrier becomes the one of the ‘big four’ to deploy a Note 9 Pie update. Global variants of the Galaxy Note 9 have already received the update, so it comes as no surprise. A Reddit user first spotted the update and several others confirmed that they received theirs in the same thread.
