The Android 5.1.1 Lollipop OTA update has finally arrived for the owners of Samsung Galaxy S6 and the Galaxy S6 Edge on AT&T. The operator has released the update just before the upcoming launch of the Samsung Pay on Monday.

The Android 5.1.1 Lollipop OTA released by AT&T for the Galaxy S6 and the Galaxy S6 users weighs 660 MB, Android Central reported. The update also carries support for Samsung Pay. The notification of the software update stated that its installation will improve the performance of the device.

The OTA update should show up automatically on the AT&T Galaxy S6 and S6 Edge devices. However, if the update does not show up, users can navigate to Settings > About device > Software update to check for the update manually. The operator recommends that in order to install the update, the handsets should be connected to a Wi-Fi network and the battery should be charged up to 50 percent.

According to Android Police, some of the AT&T users of the Galaxy S6 and the S6 Edge have failed to install the Android 5.1.1 Lollipop. The publication stated that in order to overcome the issue and to install the update successfully, users will have to enable all the disable system apps. Alternatively, users can manually set the date one day prior to the current date and then check for the update again.

T-Mobile was the first U.S. operator to roll out the Android 5.1.1 Lollipop update for the Galaxy S6 and the S6 Edge owners. Sprint, Verizon Wireless and U.S. Cellular have also released the Android 5.1.1 Lollipop update for their Galaxy S6 and S6 Edge customers. In order to make the Galaxy S6, the Galaxy S6, the Galaxy S6 Edge+ and the Galaxy Note 5 handsets ready for the upcoming Samsung Pay service, carriers like Verizon Wireless, T-Mobile and Sprint have already released fresh updates since last Friday.
