Encrypted Calls
Buzzio private calls let you place voice and video calls with someone in 1-to-1 chat. You can also share your screen. Buzzio does not keep a recording you can play back later.
Use calls when you want a live conversation with the same private-chat trust model.
Get started
- Open a 1-to-1 chat with the person you want to call.
- Tap the voice or video call control in that chat.
- Allow microphone (and camera, for video) when your phone asks.
- Or open the Call tab to see recent local call history and return to people you have called.
During a call you can mute, use speaker, turn the camera on or off, flip camera, share your screen, and end the call.
Share your screen
- On a live 1-to-1 call, tap screen share.
- Allow the system capture prompt.
- Both cameras pause so only the screen is shown. One share at a time.
Android: press Home to show another app — sharing continues from the call notification.
iOS: choose Buzzio in the system Start Broadcast picker.
Stop sharing from the in-call control when you are done.
Call tab
The Call tab shows recent calls stored on your device. Older records leave that list after about 24 hours. It is not a Buzzio cloud call archive.
Tips and limits
- Calls are part of private 1-to-1 chat — start from a chat, or return through the Call tab.
- Keep a stable network. Try Wi-Fi if cellular is weak, or the other way around.
- If someone blocks you, you generally cannot keep calling them through that private relationship.
- Media prefers a direct device-to-device path. If a relay is needed, it forwards encrypted packets only — not a recording.
- Group chat uses voice rooms, not this 1-to-1 ring-and-answer call.
Troubleshooting
The call will not connect
- Allow microphone (and camera for video) for Buzzio in phone settings.
- Confirm both people are on a network (Wi-Fi or cellular).
- Start the call from a 1-to-1 chat, not a group, community, or Whisper session.
- Check that neither of you blocked the other.
- Update Buzzio, then try again.
- If the status board at status.buzzio.dev shows an incident, wait it out.
The call connects, then drops
- Move closer to Wi-Fi, or switch Wi-Fi ↔ cellular.
- Close other apps that hog the network or microphone.
- On Android, allow Buzzio to run in the background / ignore battery optimization so the call can stay alive when you leave the screen.
Screen share does not start
- Accept the system permission the first time you share.
- On iOS, pick Buzzio in Start Broadcast — sharing will not start if you pick another app.
- Only one person can share at a time. Stop the current share, then try again.
- Screen share is for 1-to-1 calls, not group voice rooms.
I cannot hear them / they cannot hear me
- Unmute both sides.
- Check phone volume and that another Bluetooth device is not capturing audio.
- Toggle speaker, then try again.
