How to go back to mobile format

How do you go back to the mobile site? I accidentically went to the full site on my phone and it's super annoying. Q

To switch to mobile from full, at the bottom of the page look for a small drop down menu that says “LHC #” the number may be 4.2.

This may not work for you, it depends on your phone and your browser, BUT if you have an android phone and use Chrome default browser, try this.
Press the three dots on the upper right-hand side of your browser window on your phone:

Uncheck the "desktop site" box:
