How to Connect the Samsung Galaxy A71 to a TV via Wi-Fi: A Complete Guide

Wirelessly broadcasting your smartphone screen to a large TV screen has become a standard feature of modern devices. Samsung Galaxy A71 (2020 model) supports several technologies for this connection, but not all users know how to set them up correctly. The main issues are different protocols on the smartphone and TV, incompatible software versions, or simple errors in the Wi-Fi settings.

In this article we will look at three working methods connections: via built-in function Smart View, standard protocol Miracast (Screen Mirroring) and universal DLNAEach method has its own nuances, from TV model requirements to streaming resolution limitations. You'll learn how to avoid common mistakes, such as when your smartphone doesn't see your TV online or the stream keeps dropping out.

Important: If your TV was released before 2016, some features may be missing. In this case, you will need additional equipment (e.g. Google Chromecast or Mi TV Stick). We will indicate which TV models support each connection method.

1. Preparation: What to check before connecting

Before you try to connect Galaxy A71 with a TV, make sure the basic conditions are met:

• 📶 One Wi-Fi networkBoth devices must be connected to the same router. If the TV only supports Ethernet, use an adapter. Wi-Fi → LAN or customize WPS on the router.
• 🔄 Software updates: the smartphone must have the latest version installed One UI (at least 2.5), and the TV must have the latest firmware. Check in Settings → Software Update.

If your TV does not have built-in Wi-Fi (for example, older models Sony Bravia or Philips), use external adapters:

⚠️ Attention: If you use guest network on the router or turned on isolation of clients (AP Isolation), devices won't see each other. Disable these features in your router settings (192.168.0.1 or 192.168.1.1).

2. Method 1: Smart View (built-in Samsung function)

Smart View - proprietary technology Samsung, which allows you to mirror your smartphone's screen to TVs of the same brand (2016 and newer). The main advantage is minimal latency (around 50 ms) and support for resolutions up to Full HD (1080p). However, there are limitations:

• 📱 Works with TVs only Samsung on the platform Tizen (models QLED, CU8000, AU9000 and others).
• 🔒 Does not support streaming protected content (e.g. Netflix or Disney+ (due to DRM).
• 🔄 Requires enabled Wi-Fi Direct on both devices.

Connection instructions:

1. Open on your TV Settings → General → External devices → Nearby devices and enable the option.
2. On Galaxy A71 Swipe down on the screen to open the notification panel and tap Smart View (icon with a screen and waves).
3. Select your TV from the list of available devices. If it's not there, refresh the list or restart both devices.
4. Confirm the connection on TV (you may be asked to enter a PIN code).

If the broadcast is showing artifacts or jerks:

• 📶 Switch the router channel 5 GHz (in the router settings, select 80 MHz channel width).
• 🔌 Disconnect other devices from Wi-Fi that consume data (for example, laptops running torrents).
• 🔄 Reduce the broadcast resolution in the settings Smart View (to 720p).

3. Method 2: Screen Mirroring (Miracast) for any TV

Screen Mirroring (or Miracast) is a universal protocol that works on most modern TVs, regardless of brand. Unlike Smart View, it is not tied to the ecosystem Samsung, but may have a high latency (up to 200ms) and does not support sound in some cases.

Supported TVs:

• 📺 LG (WebOS 3.0 and later) - the function is called Screen Share.
• 📺 Sony Bravia (Android TV) — Cherkaslo or Miracast.
• 📺 Xiaomi Mi TV — Wireless display.
• 📺 Philips (with Android TV) - Easy Mirroring.

Step-by-step instructions:

1. Turn on the function on your TV Screen Mirroring:
   • For LG: Settings → Network → Screen Share.
   • For Sony: Settings → Network & Sharing → Miracast.

⚠️ Attention: When using Miracast on Galaxy A71 can be observed no sound when streaming video. This is due to protocol limitations. Solution: Use external speakers connected to the TV via HDMI ARC or Bluetooth.

4. Method 3: DLNA for streaming media files

DLNA (Digital Living Network Alliance) is a protocol for transferring media files (photos, videos, music) from device to device in a local network. Unlike Screen MirroringIt doesn't broadcast the entire screen, but only selected files. This is convenient for watching movies or listening to music without lag.

Advantages DLNA:

• 🎬 Supports 4K And HDR (if the TV is compatible).
• 🔊 Transmits sound without loss (unlike Miracast).
• 📁 Works with any files, including MKV, FLAC, DTS.

How to set up:

1. Turn on the TV DLNA:
   • For Samsung: Settings → General → External Devices → DLNA Devices.
   • For LG: Settings → Network → DLNA.
