Since the guide teaches you how to install SuperSU, there isn’t much use telling you about the SuperSU app that you might want to install as one of your best root apps to try on your Samsung Galaxy J7 smartphone. Just know that when the guide is done, you will always need to keep the SuperSU app available from your app drawer because it is the app that will be giving your device the root access. Further, the SuperSU also comes with a built-in security service whereby it vows never to let anything through its gates without your knowledge. There are no written guarantees with that, but that’s the general way in which the SuperSU app works. It relies on you to choose what you grant rooting privileges to and what you want to knock back. Its job is to stop everything in its path, and it does that so you can stop anything that doesn’t look right or is a potential threat.
- The following guide is written with the 2016 version of the Samsung Galaxy J7 smartphone in mind. That does not mean you can follow this guide with the 23015 edition or any other edition and expect it to work. It likely won’t and you can brick your device in the process. Follow this guide with the Samsung Galaxy J7 2016 in your hands only. You can check the model number of the handset you have by pointing to the Settings app > About Device > Model Number and double-checking your device that way. Now remember your model number and then type it into Google and see what device comes up in the results. That’s how to check your model number.
BEFORE WE BEGIN
- Download the Samsung USB Drivers on the Windows  computer and then install them before you start the rooting guide steps or else your device will not be detected by the Odin flashing application.
- Unlock the Developer Options menu from your J7’s Settings if you have not unlocked it already by tapping on the Settings app > About Device and then tap the build number more than seven times, and it will let you know on the display when you have unlocked the Developer Options menu by calling you a developer.
- Now that the Developer Options menu has been unlocked enter the same from your settings by tapping on the Settings app > Developer Options and then check the box available for the USB Debugging Mode.
