Easily Update Samsung Galaxy S7

How to Easily Update Samsung Galaxy S7 to the Newest Version of Android

With all of the fanfare about the Samsung Galaxy S7 dying out, the phone may be feeling forgotten, but it’s still a pretty spectacular phone. All it needs is some updating. So what if the S7 ran Marshmallow right out of the box? After this, the software will be almost identical.

The software comes with Now on Tap, which allows you to have useful information even faster than before. Think of it like a built-in, specialized Google for the specific app you are looking at or whatever is on your screen. Marshmallow makes searching for apps more convenient, too, with a new search button on the home screen.

Also, you finally you get more say in what your apps have access to. Rather than your options being limited to give the owners of the app whatever information they want—whether they need it or not—or forfeiting the installation of the app altogether, you will have some say with Marshmallow. These features are only the slightly crisp, slightly gooey edge of Marshmallow. You are about to find out about other features for yourself.

Method 1: Update Over-the-Air

This option is so user-friendly that your phone will most likely bring the update to your attention and then guide you through it. It comes with no risk of warranty loss. All of the major carriers have already released a Marshmallow update(s). So what’s the downside? It can be the waiting.

You don’t get to choose when you receive the update.

1. Stabilize the Internet

  • Ensure that you have a stable Wi-Fi connection.
  • If your Wi-Fi connection is unreliable, it might be best to use Methods 2 or 3 instead.

They contain ways to update Samsung Galaxy S7 without Wi-Fi. Using Wi-Fi guarantees, there won’t be any carrier data fee. Here’s how you can Fix a Wi-Fi  Connection Problem on Android if you are having troubles.

Note: You shouldn’t try to use your phone during an update. Take care of any mandatory phone tasks beforehand.


3. Check Notifications

  • Sometimes updates will show up on your phone like magic. If so, lucky you!
  • Drag downward on the Notification bar to see if there’s an update alert.

OTA updates are truly going to be the easiest option, but they do require Wi-Fi. You can check to see what updates are available on a PC without the Wi-Fi, and use a USB connection to install via Smart Switch or Odin. Odin is your best bet for a rooted phone, especially if you rooted using a custom recovery.
