Modern LG Smart TVs running the webOS operating system offer users much more than just broadcasting live channels. One of the most popular features is the ability to fully control the device using a smartphone. This is convenient if the remote is lost, the battery is dead, or you simply want to use the phone screen as a trackpad for typing. Control via Wi-Fi It turns your gadget into a universal console, allowing you to not only change channels, but also launch apps, control volume, and even display your smartphone's screen on a larger display.
The basis for the implementation of this function is a wireless local area network. Wi-Fi connection Provides the necessary data transfer speed for instant command response. Unlike infrared, which requires line of sight, a radio signal penetrates furniture, allowing you to control your TV from anywhere in the room. It's important to understand that stable operation depends not only on the software but also on the router's signal quality.
In this guide, we'll cover all available connection methods in detail, review official LG apps and third-party alternatives, and discuss potential syncing issues. You'll learn how to set up the feature. Smart Share and you'll understand how to turn your phone into a fully-functional remote control Magic Remote.
Preparing equipment and network
Before setting up the software, you need to make sure your home network is ready to work with multimedia devices. The first and most critical requirement is that both devices—the TV and the smartphone—are on the same subnet. This means they must be connected to the same router.
Users often encounter a situation where their phone is connected to a guest Wi-Fi network and their TV is connected to the main network, or where one device uses the 2.4 GHz frequency and the other 5 GHz, and the router isolates them. For successful synchronization, DLNA protocol or proprietary LG systems must "see" each other on the local network.
- 📶 Make sure your LG TV is connected to Wi-Fi via the menu
Settings → Network → Connect to a Wi-Fi network. - 📱 Make sure your smartphone (Android or iOS) is connected to the same access point.
- 🔌 If your router is dual-band, try connecting both devices to the same frequency (e.g., 5 GHz only) if you experience detection issues.
⚠️ Note: Some providers use Carrier Grade NAT technology or AP Isolation at the hardware level. If your TV and phone are on the same network but can't see each other, check your router settings to see if they're blocking local traffic exchange between clients.
It's also worth checking your TV's software version. Older versions of webOS may not support the latest encryption protocols used by the latest mobile OS versions. A firmware update often resolves issues with the device's visibility in the list of available devices.
LG ThinQ Official App: Installation and Setup
LG has developed its own payment ecosystem called LG ThinQ (formerly known as LG TV Plus). This is the most stable and functional control method, as the app was created directly by TV developers and has access to all system functions.
The installation process is standard for both mobile platforms. Go to the app store (Google Play or App Store), search for "LG ThinQ," and download the app. After installation, you'll need to create an LG account or sign in to an existing one, although basic remote control is often available without extensive authorization.
☑️ Check before connection
When you first launch the app, it will automatically scan for the network. Once your TV is found, a connection confirmation message will appear on the TV screen. You'll need to approach the TV and tap "Allow" or enter the code displayed on the screen into the app on your phone. This is a security measure to prevent unauthorized access to your device.
- 📲 Download the app LG ThinQ from the official store.
- 🔐 Register with LG Account to save your settings.
- 📺 Click the "+" button in the app to add a new device.
- ✅ Confirm the pairing by checking the code on the TV and smartphone screens.
The app's interface mimics a standard remote control but adds touchpad functionality. You can swipe your finger across your smartphone's screen to move the cursor on the TV, which is especially convenient for navigating the browser or YouTube app. ThinQ also lets you share photos and videos from your phone's gallery to the big screen.
Alternative: LG TV Remote & Cast app
If the official app seems cluttered or unstable on your phone model, consider third-party developments. One popular solution is LG TV Remote & CastIt often works faster and has a simpler, more intuitive interface, free of unnecessary "smart home" features.
The operating principle is similar: the app scans the network, finds the TV, and requests access. However, some third-party programs may use different remote emulation methods, which can sometimes help when the official software "loses" the TV. This is especially true for LG models released several years ago.
⚠️ Warning: By using third-party apps, you're giving an unknown developer control over your TV. We recommend choosing apps with a large number of positive reviews and a proven track record, avoiding dubious software with excessive permissions.
These apps often feature a convenient keyboard for text input. Typing YouTube search queries or website addresses using a TV's on-screen keyboard is inconvenient, while typing text on a smartphone takes seconds. The text is instantly transmitted to the TV via local network.
Why can't my phone see the TV?
If the search yields no results, check whether your phone's antivirus or router's firewall is blocking local connections (UDP ports). Also, try rebooting the router—this refreshes DHCP leases and may resolve IP address conflicts.
An additional benefit of some alternative apps is macro support. You can program a sequence of actions, such as "Turn on TV → Launch Netflix → Set volume to 20%," and launch it with a single tap. This turns an ordinary smartphone into a powerful automation tool.
Screen Share
Controlling a TV is not just about changing channels, but also about being able to display content. Technology Screen Share (or Miracast in Android terminology) allows you to broadcast the image of your smartphone's entire screen to your LG TV without using cables.
To start casting on LG TVs, you typically need to launch the "Mobile Display" or "Screen Share" app in the Smart TV menu. On Android, the feature is often integrated into the notification shade and called "Cast," "Smart View," or "Project." iPhones use AirPlay 2 technology, which is supported by most modern LG models.
The quality of the broadcast directly depends on your bandwidth. Wi-Fi channelStreaming high-resolution video (Full HD or 4K) requires a stable signal. If the image is choppy or has low resolution, try moving closer to the router or reducing the network load by disabling downloads on other devices.
| Function | Description | Required OS TV | Stability |
|---|---|---|---|
| LG ThinQ | Full remote control + media | webOS 3.0+ | High |
| Screen Share | Screen mirroring | Any Smart TV | Average |
| AirPlay 2 | Broadcasting from iOS | webOS 4.0+ | High |
| DLNA | Photo/video files only | Any Smart TV | High |
When using the mirroring feature, notifications, messages, and calls will also be visible on the big screen. It is recommended to enable "Do Not Disturb" mode on your smartphone before watching.
Solution: Why is there no connection?
Despite the apparent simplicity, users often encounter problems when trying to connect their phone and TV. The most common error is "Device not found." In 90% of cases, this is resolved by ensuring both devices are on the same subnet, as mentioned earlier.
Another possible cause could be an outdated version of the app or TV firmware. Manufacturers regularly release updates to patch security holes and improve compatibility. If the app worked yesterday but doesn't today, check the app store for updates.
- 🔄 Restarting your router, TV, and smartphone is a classic but effective method for clearing network errors.
- 🛡️ Check your antivirus settings on your phone; sometimes it blocks local connections, considering them suspicious.
- 📡 Make sure that the "Mobile TV On" function or a similar one is enabled in the network settings on your TV.
⚠️ Note: The LG TV menu interface may vary depending on the webOS version and model year. If you can't find the item you're looking for, use the settings search (magnifying glass in the upper corner) or consult the official documentation for your specific TV series.
If the problem persists, try forgetting the Wi-Fi network on your TV and reconnecting it using the password. Sometimes the network settings cache accumulates errors that prevent devices from properly connecting. It's also worth checking if your router has a limit on the number of connected clients.
Additional features and hidden functions
Using your phone as a remote control gives you access to features that are difficult to implement with a regular IR remote control. For example, the function text input Allows you to instantly enter Wi-Fi passwords, browser search queries, or app logins. This eliminates the tedious process of selecting letters on the screen.
Some apps allow you to use your smartphone's microphone for voice search on your TV, even if the remote control doesn't have a microphone button or it's not working properly. Simply press the button in the app, say your command, and the TV searches.
The app also lets you browse the contents of USB drives connected to the TV. This is convenient if you need to quickly find a specific movie on the flash drive without scrolling through long file lists using the buttons on the remote. File navigation on a smartphone's touchscreen is significantly faster and more convenient.
Power consumption is an important consideration. Constantly using the Wi-Fi module and smartphone screen as a remote control can drain the battery faster. However, compared to searching for a lost remote or buying batteries, this is a small price to pay for the convenience of control.
Frequently Asked Questions (FAQ)
Is it possible to control an LG TV without a Magic Remote?
Yes, you can. The mobile app completely replaces the remote's functions, including the mouse cursor. You don't need a physical Magic Remote for initial setup or everyday use, as long as your smartphone is connected to the same Wi-Fi network.
Does Wi-Fi control work if the internet is disconnected?
Yes, it works. You don't need internet to control your TV from your phone via Wi-Fi; only a local network (router) is essential. Devices must be able to see each other on the network, even if there's no access to the global network.
Why can't the LG ThinQ app detect my TV?
The most likely cause is that the devices are connected to different networks (for example, one to 2.4 GHz, one to 5 GHz with isolation, or one to a guest network). Also, check that the mobile device connection feature is enabled in the TV settings.
Is it possible to turn off the TV via the app?
Yes, most remote control apps have a power button. However, to turn on the TV for the first time (from a completely powered-off state), you may still need to use the physical remote or the button on the TV, as the Wi-Fi module may be disabled in sleep mode.
Do older LG models (Non-Smart) support phone control?
No, regular TVs without Smart TV functionality and Wi-Fi can't be connected to the network, meaning they can't be controlled via a phone. There are special IR adapters for them that plug into the phone's headphone jack, but this is a separate technology.
