Let’s look at the conclusion first

If Floating AI Follow offers a Remote phone microphone option, the other phone can scan the host QR code and explicitly enable its microphone. This path needs overlay permission on the host, but no host microphone or accessibility permission. The accessibility and host-microphone instructions below apply to local capture only.

The floating window disappears during use, usually because the permissions are modified by the system or security tools, the application process is cleaned up, or the window position changes after the screen is rotated. Reconfirm the suspension permission first, and then restart the current session.

Troubleshooting steps

1. Return to Tdx Teleprompter and confirm whether the current floating session has stopped.
2. Go into system settings and check that "Show on top of other apps" is still allowed.
3. Check battery saver, background activity, auto-clean, or phone manager settings to keep Tdx Teleprompter running during recording.
4. In the case of floating AI, also confirm accessibility services and microphone permissions.
5. Return to the app and restart, then switch to the target camera.
6. Check the edges of the screen after switching between horizontal and vertical screens, and re-move and adjust the window as needed.
