Within a day or three i will share my Samsung S7 navigation bar that uses Swiftly Switch Pro plus Tasker, AutoInput ,and optionally AutoTools. Web screens are another approach if Swiftly is not your cup of tea.
The left and right physical touch buttons trigger slide out menus so no more hotspot getting in the way.
The navbar has to use a hotspot to slide out from the bottom edge but I might bind it to something else.
