How can I resolve Miracast connection issues on my WISELAZER A30 projector where only sound works after the first successful connection?

Based on the WISELAZER A30 manual and common troubleshooting for Miracast, please try the following steps to resolve the issue where only sound is transmitted during reconnection:Check Network Frequency: Ensure both your smartphone and the projector are connected to the same WiFi network. The A30 supports both 2.4G and 5G; if your router has both, try switching both devices to the 5G band for better bandwidth, or ensure they aren't jumping between different bands.Clear Miracast Cache: On your Android device, go to Settings > Apps, find the system app responsible for "Wireless Display" or "Cast," and clear its cache and data. This often resolves handshake issues that occur after the initial pairing.Restart Network Hardware: The manual suggests restarting both your smartphone and your router to clear network interference that might be blocking the video stream.Verify Device Compatibility: Ensure your phone's "Wireless Display," "Smart View," or "Cast" function is fully updated. Some HDCP-protected content (like Netflix or Disney+) will only play audio and show a black screen over Miracast due to copyright restrictions; test with a local gallery video or YouTube to see if the video returns.Toggle WiFi: Instead of a full factory reset, try simply toggling the WiFi off and on within the projector's Setup menu before attempting to reconnect.If the problem persists only after exiting and returning, it may be a software handshake bug. Ensure you are selecting Miracast on the projector screen before initiating the cast from your phone each time.
