If the first touch of "allow" shows an error message, simply try a second time. Be sure to reboot your phone after changing the setting!
Note: You don't need to prepare anything on the Nexus 5 with stock Marshmallow (except root)! Just run the app.
Note: On 64 bit phones a "test mode" must be set and the phone rebooted to successfully make the necessary change. Some phones don't keep the "test mode" setting after the reboot, so they are not compatible. This is true e.g. for the Oneplus Two.
