What should I do if Google Home can't see my TV?
Make sure AP Isolation isn't enabled on your router. This feature prevents devices on the same network from seeing each other. Also, check if UPnP is enabled in your router settings.
Solving common connection problems
Despite the simplicity of the technology, users often encounter situations where the phone doesn't detect the TV or the connection constantly drops. Most often, the problem lies in network settings or software glitches. First, try restarting both devices—this solves 80% of software issues.
If your devices are on the same network but can't see each other, check your router settings. Some providers or router models isolate wireless clients from each other by default for security reasons. You need to access your router settings (usually via the address 192.168.0.1 or 192.168.1.1) and find the setting AP Isolation or Client Isolation, and then turn it off.

When using third-party software, always check the requested permissions. Screencasting apps don't need access to your contacts or SMS messages. Limit access rights to the bare minimum to ensure the security of your personal data.
Is it possible to share a screen without a Wi-Fi router?
Yes, this is possible thanks to Wi-Fi Direct technology. Your phone and TV create a direct connection. In this case, your phone's internet connection may stop working (unless you're using mobile data at the same time), but the image streaming will continue. Smart View often uses this method by default.
Why is there no sound when broadcasting an image?
Most often, sound is blocked due to DRM (copyright protection) restrictions in apps like Netflix or Disney+. These prevent audio output through unlicensed transmission channels. In other cases, check whether your phone is set to silent mode or whether the media volume is turned down in Bluetooth device settings.
Does broadcasting affect internet speed?
When using Wi-Fi Direct, no, the traffic is transmitted locally. When streaming through a router (Chromecast/SmartThings), part of the bandwidth is occupied by the video stream, which can slow down page loading speeds on other devices on the network, but is usually not critical for HD content.
