The Android Back Button is missing in the newer version of android, this video we don't go through how to bring the back button, and the entire bottom navigation back.
In the newer versions of android the navigation is done by gestures, not everybody like gestures or find them comfortable, myself I prefer to always have a back button, and the home button available to me.
So this quick video focuses on bringing back the bottom navigation that were available in previous android versions by default.
