LG televisions use Screen Share. Of the 8 Android phone families we track, 5 can mirror to one over Wi-Fi, and 3 cannot at all because the two devices share no protocol.
| Phone | Result | Shared protocol |
|---|---|---|
| Samsung Galaxy | Works | Miracast |
| Google Pixel | Not over Wi-Fi | None |
| Xiaomi / Redmi / POCO | Works | Miracast |
| OnePlus | Not over Wi-Fi | None |
| Motorola | Not over Wi-Fi | None |
| OPPO / realme / vivo | Works | Miracast |
| Tecno / Infinix / itel | Works | Miracast |
| Huawei / HONOR | Works | Miracast |
Three steps, and the first is the one that decides whether the other two matter.
Find your phone in the table above. If it says Not over Wi-Fi, stop here - no app or setting will change that, and the fix is an adapter or a Chromecast.
Home, then Screen Share - open it on the TV before scanning from the phone
Same Wi-Fi network and same band on both. Several brands only advertise themselves once mirroring is already open on the TV, which is why scanning first so often finds nothing.
There is no software fix for a missing protocol. Both of these are more reliable than wireless mirroring anyway.
Samsung Galaxy, Xiaomi / Redmi / POCO, OPPO / realme / vivo, Tecno / Infinix / itel, Huawei / HONOR can mirror to an LG TV over Wi-Fi. Google Pixel, OnePlus, Motorola cannot at all, because those phones and LG televisions share no mirroring protocol - no app can bridge that.
Home, then Screen Share - open it on the TV before scanning from the phone. LG televisions use Screen Share.
On 2018 to 2020 webOS models the TV only becomes discoverable while the Screen Share app is open in the foreground. Most guides tell you to scan from the phone first, which is exactly why the TV never appears in the list. If your phone and TV do share a protocol, the next things to check are that both are on the same Wi-Fi network and the same band, and that the network is not a guest network with client isolation switched on.
LG televisions accept Miracast.
Still stuck? Work through why a TV does not show up when you scan or why mirroring keeps disconnecting.
