Update At&t Galaxy S7/Galaxy S7 Edge to Official Android Nougat

Here is the easiest method to update At&t Galaxy S7 or Galaxy S7 Edge to official Android 7.0 Nougat.

Samsung rolled out the Nougat update for Galaxy S7 and S7 Edge last month. The update was pretty late from the South Korean giant. After rolling out the update for S7 and S7 Edge, Samsung didn’t want to push the break, it kept on rolling out the update in several regions. Carriers like At&t and Verizon also followed Samsung’s footsteps and turned out kind to their users. Verizon and At&t released the updates for their users in the form of OTAs. If you own an At&t branded Galaxy S7 or Galaxy S7 Edge, you certainly fall in the lucky bracker and you can manually force-update your phone to Android 7.0 Nougat now. The manual update is recommended for the users who are unable to capture the latest update in the About device > Software info > updates menu.

The update is available in the form of multiple OTA files. In case you are on an older version of Android on your phone, you have to go through multiple OTA files to reach out the latest and stable build of Android Nougat. The procedure is quite easy. All you have to make sure is you follow the instructions to the letter to avoid any kind of mishap during the installation process. You have to perform all the updates in a sequence.
