Samsung Galaxy S6, S6 edge and S6 active receiving Android 7.0 Nougat update at AT&T6
If you happen to own the AT&T Galaxy S6, Galaxy S6 edge or Galaxy S6 active, then you should check for Android 7.0 Nougat, as the carrier confirmed the rollout has already begun.
Keep in mind though that the update weighs in at around 1.3GB for each of the three smartphones, so make sure you have enough free storage before attempting to download and install Android 7.0 Nougat.
Luckily, AT&T published all three changelogs for the updates, which look similar. In fact, aside from the size and firmware number, the updates are the same for all three Galaxy S6 variants.
The update brings Samsung Cloud and Samsung Pass, as well as other fixes and enhancements. Also, the AT&T Address Book and MobiTV apps have been removed. As far as security update go, the carrier confirmed the Android 7.0 Nougat update includes the April security patch, too.
It's worth pointing out the update is delivered via OTA, so it might take up to a week to arrive on all eligible devices. If it doesn't appear on your phone right away, you should check again tomorrow.
