Samsung televisions use Screen Mirroring / Smart View. 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.
Source, then Screen Mirroring - or simply accept the prompt that appears on the TV
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 a Samsung TV over Wi-Fi. Google Pixel, OnePlus, Motorola cannot at all, because those phones and Samsung televisions share no mirroring protocol - no app can bridge that.
Source, then Screen Mirroring - or simply accept the prompt that appears on the TV. Samsung televisions use Screen Mirroring / Smart View.
Samsung TVs do not include Chromecast built-in. If your phone has no Miracast sender - a Pixel, most current OnePlus and Motorola models - it cannot mirror to a Samsung TV over Wi-Fi at all, no matter which app you install. 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.
Samsung televisions accept Miracast.
Still stuck? Work through why a TV does not show up when you scan or why mirroring keeps disconnecting.
