If you have a Samsung Galaxy S8 or S8+ and you want to reset it, there are a few things that you can do. First, make sure that your phone is turned off and unplugged. Then, go to the Settings app and open the Reset button. Next, type in your phone’s model number (it will be in the form of a number like “S8” or “S8+”) and press Reset. Finally, confirm that you want to reset the phone by pressing Reset again. If all of these steps don’t work, then you may need to get help from a Samsung representative.
