Facebook is constantly making minor adjustments to its interface and layout for easier viewing or navigation. Lately, social networking has been making more significant changes, and now some users have been catching tests with a new menu accessed on mobile devices.
The biggest visible change is the presence of a large “F” with the company logo in the bottom bar, between the News Feed icon and the notifications icon. This button would serve to access the same options we opened in the "hamburger" tab in the upper right corner.
Below, you can see well what changes. There is a slight change of position of the topics and the icons remain the same; however, each section is highlighted in white background labels – making it easy to tap for selection on tablets and smartphones. In addition, access to your profile and search are also easier at the top.

These changes have now only appeared for some people in version 246.0.0.49.121. Whether this experience really will turn into a stable update is not yet known, and there is no distribution forecast for everyone.
