If you aren't already logged in, enter your email address (or phone number) and password, then tap Log in. It's either in the bottom-right corner of the screen (iPhone) or the top-right corner of the screen (Android). This option has an icon of a white flag on an orange background next to it. It's near the top of the screen. Skip this step on Android. This option is at the bottom of the page, below the "Liked Pages" heading. Doing so opens a list of your current interests. It's to the right of the page's name. It's at the bottom of the drop-down menu. This will unlike your selected page, though the page won't disappear from your Liked Pages until you re-open Liked Pages. You can repeat this process for each page you want to unlike.
