The benefit of using an Android-powered device is the freedom that you get with the device and it looks like Google might be planning to offer their users, even more, freedom in the new Android 7.0 Nougat.
According to Android Police, the Nougat code suggests that Google might be planning to offer a new navigation bar customization tool. They added that the tool will allow users to actually delete some of the pre-set buttons like Home, Back and Recent and replace them with some other buttons.
Users can also move the buttons around and resize them. Of course, nobody knows when Google plans to offer this new feature but some of them think that we might see it when Google release the first maintenance update for the Android Nougat while others think that this features might only be offered a future operating system.
