If you're a Samsung Galaxy S6 or S6 Edge owner and you're a subscriber of AT&T, we have some good news for you. Starting today, owners of either handset will receive an update to Android 5.1.1.
Android 5.1.1 is currently the latest and greatest version of Google's Android operating system, that is, until September 29. The update will be rolling out via OTA in waves, so it may be today, tomorrow or the next day that your handset gets the notification to update. If you're impatient, you can check in your settings under About and software updates.
With the new update, users will get access to Samsung's new wireless payment service, ‘Samsung Pay'. Which begins on September 29 if you live in the United States. Samsung advises users to have at least 50% battery life prior to beginning the update. In addition, you might want to connect your handset to a stable Wi-Fi connection in order to avoid data overages. Happy updating!

Except we’re not, you can download it but then it fails to install then you gotta wait 24hrs before you can try again.
You can just change your clock from auto-update and set the date 24 hours ahead and try again. I also read somewhere that someone who was having issues with the failure to install enabled all his disabled apps and tried again and it worked. Not sure if that was a fluke, but may be worth a try.
Nope. It didn’t work for me.
