About this app

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.

PRO Features (Free Trial Available)
- Use a Custom Button (i.e SOS/Programmable/Camera buttons) for PTT
- Use any supported PTT App (Normally only Zello/MS Teams/VoicePing)
- PTT Only when screen is ON: Useful if your PTT button is too sensitive
- Lock Screen with quick open for your Walkie Talkie App

How It Works
The fastest way to start or reply to PTT
1: Press Power button to wake up phone
2: Hold Volume Down/Custom button to PTT in the previously selected Zello/MS Teams/VoicePing Channel

Required Setup
1: Install your Walkie Talkie App
2: Install Fast Talkie
3: Enable Accessibility Permission for Fast Talkie
4: Hold your selected PTT button to PTT

Verified Phone models that work with custom button even when screen off
- Samsung Xcover Pro, Samsung Xcover 7
- Blackview Series, Ulefone, Kyocera, Zebra, Unihertz, Sonim, Siyata, Bittium

It's okay, I like that it's easier to access the app without having to open it, but I don't like the fact that I have to sacrifice the buttons, like the volume down button's function, just for this to work. It would be nicer if you could use button combinations, like the volume up and down buttons, to easily access it without having to sacrifice the buttons' function, or have it also be the power button, which I can still use to turn off my phone with the power and vol down button combination

I have a Blackview phone with a Side Key. FastTakie sets up the Side Key for use by Zello via enabling Accessibility for FastTalkie. I discovered that Settings/Battery/Battery optimation/ALL APPS/FastTalkie needs to be disabled to prevent FastTalkie Accessibility from getting disabled. Duraspeed does not exist on the phone. After 100 Side Key uses FastTalkie wants $15. That's extreme!

Blackview phones will auto disable accessibility on each restart. You can also turn off duraspeed and add Fast Talkie to white list. Thank you for financially supporting our app if you find it useful.

This thing is a mess! It's holding me at the permissions stage, but it's not telling me which permissions I need to grant. There's a ton and I keep checking them all off but I still can't proceed past the first screen. What a horribly designed app with zero instructions!
