Automatic speaker enable/disable option (PHONES)

Right now you can enable having a speaker in a call if you go to settings, sometimes you don't want the speaker because you want to put your phone against your ears, so why not doing it like a normal phone would? Use the phone sensor to determine if there's an object and dark/lock the screen so your face don't type random stuff + disable the speaker option in settings, if you lift the phone again it reverts, if you have earphones plugged in this feature is automatically disabled. Thanks for reading.
