To be honest, I don’t really see how to hide navigation bar on Android Pie. I mean, yes, Google has done the right thing and announced to do a gesture to hide the navigation bar. However, I feel that the best feature for the Android Pie could be not the gesture but the other ones that have been introduced in this version of the OS.
The navigation bar has been introduced to be able to simplify the browsing experience and this is so because the minimalism approach of the OS will allow users to keep the current URL or page. So, if you want to hide the navigation bar in Android Pie, you need to do so by using the search option from the home screen. However, this may not work properly as the search box is hidden.
Navigation bar will still be visible even if you use it for the first time. However, the action needed for getting the navigation bar will also get executed. This means that the navigation bar will be activated only when the gesture or swipe is done. This means that it won’t take long before the navigation bar gets activated.
Now, to avoid activating the navigation bar when you need it most, you can hide it in its default state by using a swipe up gesture. The gesture will simply be activated when the navigation bar is positioned over the topmost app icon on the home screen. Yes, I know that I said that the gesture will be activated when you use the home button to do so, but you are bound to execute the gesture when you tap the home button too.
What you should do after swiping up the gesture is to swipe to the left to dismiss the navigation bar. I am not sure why the device is showing the bar again after dismissing it. But, I am pretty sure that once you dismiss the bar, you will be able to do it without any problem. This is how to hide the navigation bar on Android Pie.
Another cool feature introduced with Android Pie is the quick settings. As the name suggests, these functions help you to quickly switch between the preinstalled apps and give you access to some important information. The quick settings are especially helpful when you are in a situation where you don’t know which app to use.
The quick settings can be quickly accessed using a gesture from the touch screen. If you want to disable the quick settings function, all you need to do is to swipe to the right and it will be disabled.
So, I don’t see how to hide navigation bar on Android Pie. Hopefully, I was able to convince you to use other gestures to have access to the navigation bar and other quick settings.
