Solutions to common problems and errors
Despite the simplicity of the technology, users often encounter difficulties. The most common issue is that the TV doesn't detect the phone, or vice versa. This is often due to one of the devices being in power-saving mode or sleeping. Make sure both devices' screens are active when searching.
Another common cause of failures is channel congestion. If there are many neighboring routers operating on the same frequency, the signal Wi-Fi Direct The signal may be lost. In this case, changing the channel in the router settings (if it's used as a bridge) or simply rebooting the Wi-Fi module on the TV via the "Airplane Mode" menu helps.
It's also worth mentioning the issue of audio and video desynchronization. This is a classic sign of insufficient bandwidth or poor performance of the TV's processor when decoding the stream. Reducing the streaming image quality in the source app settings often resolves this issue.
Secret Method to Reset Network Settings
If all else fails, try resetting your network settings to factory defaults. To do this, go to Settings → Device → Reset → Reset network settings. This will delete all saved Wi-Fi passwords, but it often resolves deep software driver conflicts.
