iOS App Black Screen After Session Reconnection

The iOS app displays a black screen after losing the session and successfully reconnecting. Audio continues to work normally, but the video/screen content is not rendered.

Steps to Reproduce

  1. Open the iOS app

  2. Establish a connection/session

  3. Lose the session (network interruption, backgrounding app, etc.)

  4. App automatically reconnects successfully

  5. Screen remains black despite audio working

Expected Behavior

After successfully reconnecting, both audio and video should be restored and the screen should display content normally.

Actual Behavior

  • Audio works correctly after reconnection

  • Screen remains black/blank

  • User cannot see any visual content

Additional Context

  • This appears to be a UI rendering issue rather than a connection issue

  • The session reconnects successfully (audio confirms this)

  • Only the visual rendering is affected

Sorry for late reply I tested what you have said in our ios beta glkvm. I don't find any issues about the screen while I have tried the smart mode and normal mode about the video mode. It doesn't matter because the kvm-ios is still in beta.

There is an issue that the Audio is always disabled which is inverted to what you have faced.

The issue was caused by aggressive CGNAT policy and short NAT timeouts from my mobile network operator. Thankfully I managed to solve it (solution here: link).

However I noticed that when I lock phone for longer than 10-15min session is not able to recover.

I tested the lock iphone and get trouble with this issue, thank for your bug sharing, I would submit it to our development team.

Do you mean it cannot recover automatically?We will improve the recovery mechanism in the next version.
