This one comes via PCMag’s Ben Moore. To turn this on, head to the Settings app’s About Phone section, go down to the Build number and tap on it seven times. Then head to Settings > System > Advanced > Developer Options. From here, you can show screen taps, change Bluetooth device options, and set USB connection preferences, along with many other settings only of interest to developers. This one is definitely only for the extreme tinkerer, and not for the technophobe.
