Encrypted voice and video calls

How to use

1. Open a 1-to-1 chat.
2. Start a voice or video call.
3. Allow microphone / camera when prompted.
4. On a live call, tap screen share. Both cameras pause; one share at a time.
5. Android: press Home to share another app from the call notification.
6. iOS: choose Buzzio in Start Broadcast.

The Call tab stores recent calls on your device (about 24 hours). Buzzio does not keep a server recording.

Troubleshooting

1. Microphone / camera permissions.
2. Stable network; try Wi-Fi ↔ cellular.
3. Call only from a 1-to-1 relationship path — not a group ring.
4. Blocks prevent calling that private relationship.
5. Screen share: accept the system prompt; on iOS pick Buzzio; only one share at a time.
6. Android battery restrictions can drop background calls — allow unrestricted battery for Buzzio.
