How to Mirror Your Phone's Screen to a Samsung Smart TV via Wi-Fi: All the Methods for 2026

Wirelessly broadcast your smartphone screen to Samsung Smart TV Wi-Fi opens up new possibilities for viewing content: from streaming high-definition video to showing presentations or games on a big screen. However, many users encounter compatibility issues, image lag, or sudden connection drops. This article will help you understand which connection method to choose depending on your phone and TV model, as well as how to troubleshoot common issues without calling a technician.

We have tested all current streaming methods on devices. Samsung 2020–2026 production years — from standard Miracast to a proprietary solution Smart View, as well as alternative services like Google Cast And DLNAWe paid special attention to the nuances of router settings that affect connection stability: Wi-Fi channel selection, traffic prioritization, and bandwidth limits. If your TV isn't detecting your phone or the stream is choppy, there's a separate diagnostic section in this article.

Important: All instructions are valid for phones on Android 10 and newer (including Samsung Galaxy S22/S23/S24, Note 20, A54/A73 etc.), as well as for Samsung Smart TV at the base Tizen OS (series QLED, Neo QLED, Crystal UHD, The Frame etc.). Older models (before 2018) may require additional adapters or a firmware update.

1. Preparing your phone and TV for broadcasting

Before connecting, make sure both devices meet the minimum requirements and are on the same Wi-Fi network. This is critical: if your phone is connected to mobile data (4G/5G) and your TV is connected to a different router, streaming will not work.

To check the network on your TV, go to Settings → General → Network → Network StatusOn your phone, open Settings → Connections → Wi-Fi and compare the network name (SSID). If the networks are different, connect both devices to the same router. It is optimal to use 5 GHz band - It provides lower latency and a more stable signal for video streaming.

Also check:

• 🔋 Phone battery charge — Screencasting consumes up to 30% of the battery per hour. We recommend connecting the device to a charger.
• 📶 Wi-Fi signal strength — If the indicator shows 1–2 bars, the broadcast will lag. Move the router closer or use repeater.
• 🔄 Firmware updates — on TV: Settings → Support → Software Update, on the phone: Settings → Software Update.
• 🚫 Ad blockers/VPNs - they can interfere with work Google Cast And Smart View.Temporarily disable them.

⚠️ Attention: On some models Samsung Smart TV 2019–2020 function Smart View may be disabled by default. To enable it, go to Settings → All settings → General → External devices → Device connection settings and turn on the option Remote access.

2. Method 1: Smart View (Samsung's proprietary solution)

Smart View - this is a proprietary technology Samsung, which provides minimal delays and supports broadcasting in resolutions up to 4K@60fps (on compatible devices). It works according to the protocol Miracast, but with optimizations for the ecosystem Samsung.
