Use your Volume button or any programmable hardware button to instantly start Push-To-Talk (PTT) on walkie talkie apps such as Zello, Microsoft Teams Walkie Talkie, and VoicePing. Fast Talkie turns your smartphone into a true radio-style PTT device. Simply hold your chosen button to talk — no need to unlock the phone or open the app. On some Phones, you might even be able to PTT with the screen off. This app uses Accessibility permission to detect button presses and trigger PTT instantly.
