Here are the steps to take your phone out of demo mode. 

1. Go to the device's settings. There are 2 ways to get to them.
   • Swipe up from the notification panel, and click on the settings icon.
   • Find the device's settings app in the app menu.

2. Find the About Phone section. Usually, you'll need to scroll down to the very bottom.

3. Click on Software Info and click 5 or 7 times on the Build Number button. This will enable developer options.

4. Go into the first setting panel again and click on Developer Options. It should be just under or on top of "About Phone".

5. Scroll down until you find Demo Mode. Enable it, and you're finished!
