Good news this morning for those of you who have the Samsung Galaxy S6 Active from AT&T. The U.S. carrier has released the Android Marshmallow update for the device and it is rolling out now. The update is build MMB29K.G890AUCU3CPE4 for those keeping score at home and it weighs in at a hefty 1.44GB. That means you will most certainly want to download this via Wi-Fi which, depending on your network, could take 20-30 minutes to download. Once you have it downloaded, the installation of the update will take another 20-30 minutes and will require a phone restart. Make sure you have any local files (docs, photos, etc) backed up to your favorite cloud service just in case things so pear shaped.
