Samsung is rolling out Android 11 to the AT&T Galaxy Tab S7 2021/01/19 2021/02/15 Samsung has been diligently following its Android 11-based One UI 3 rollout schedule and has even surprised us with a few early updates. Shortly after pushing the new software to its flagship smartphones of the last two years, the South Korean giant is now rolling out Android 11 to the Galaxy Tab S7 and the S7+. However, instead of One UI 3, the Android tablets are getting One UI 3.1, making them the only devices other than the S21 series to have it so far. Now that the Wi-Fi version and the Verizon variant have already received the update, AT&T subscribers are in for the treat.
