I'm using an NFC tag in my vehicle to do the following: 1. Enable AutoGuard app. 2. Turn Speakerphone ON. Sounds simple but for the life of me I can't get Speakerphone to come on. Using NFC Task Launcher, I call up the task "Speakerphone" that I created in Tasker (as a task). The Task is Speakerphone Set On. That's it. But it doesn't work. Can someone help please? Thanks.
