Many things have been said of Android P and more will be emerging as time passes and its next release at least in beta. Now comes a new use that would make it more profitable to the smartphone, in particular as mouse and keyboard.
Until now it has been said that will have native support of iris scan, as well as call barring.
According to some leaks on the system, you can use as the keyboard and mouse by Bluetooth. This is not an innovation, since from 2016 it is present. What is new is that now it would no longer be necessary to root for both functions.
No matter if it is on Android P (Pie, Pop or Popsicle), are functions that will be of great help to anyone who makes presentations or has to use as multimedia their devices.
