How to Control LG TV using a Phone without WiFi [4 Methods]

Lost your LG TV remote? WiFi down? Don‘t worry—you‘re not stuck with an unresponsive TV. Whether your remote is missing, broken, or the batteries died at the worst possible moment, there are several reliable ways to control your LG TV using just your smartphone—no WiFi needed.

In this comprehensive guide, I‘ll walk you through four practical methods to regain control of your LG TV without depending on a WiFi connection. These solutions work for most LG Smart TV models and require minimal setup.

The Growing Problem of Missing TV Remotes

According to a 2022 consumer electronics survey by Consumer Reports, the average household misplaces TV remotes approximately 5.2 times per month, with 71% of respondents reporting significant frustration when unable to control their smart TVs. For LG TV owners specifically, this problem is compounded by the fact that many of the TV‘s advanced features are only accessible through remote control navigation.

LG Electronics holds approximately 12.8% of the global TV market share as of 2023, with over 29 million units shipped annually. Their WebOS platform powers most of their smart TVs, but accessing its features typically requires either:

1. The physical remote control
2. The LG ThinQ app connected via WiFi
3. Alternative control methods (which we‘ll explore)

Let‘s dive into why WiFi-dependent solutions aren‘t always reliable and explore better alternatives.

Why WiFi Isn‘t Always the Answer

While the LG ThinQ app is the manufacturer‘s official solution for controlling your TV with your phone, it has one major limitation—it requires both devices to be connected to the same WiFi network. This becomes problematic when:

• Your home WiFi is down (ISP outages affect approximately 3.4% of households on any given day)
• You‘re at a location without WiFi access
• Your TV isn‘t connected to your network
• You‘re experiencing connectivity issues

According to a 2023 networking reliability study, the average home experiences 17.3 hours of internet downtime per month. During these periods, WiFi-dependent TV control solutions become useless.

Additionally, LG‘s own support data indicates that approximately 22% of customer service calls involve connectivity issues between their ThinQ app and their smart TVs, even when WiFi is functioning properly.

Thankfully, alternative methods exist that bypass this requirement entirely. Let‘s explore them in detail.

Method 1: Use Your Phone‘s Built-in IR Blaster

Many Android phones manufactured between 2012 and 2018 came equipped with an infrared (IR) blaster—the same technology used in traditional TV remotes. If your phone has this hardware feature, you can transform it into a universal remote without needing WiFi.

The Science Behind IR Blasters

IR blasters work by emitting infrared light pulses that are invisible to the human eye but detectable by the IR receiver in your TV. These pulses are encoded with specific commands (like volume up, channel change, or power toggle) that your TV interprets.

The technology operates at wavelengths between 940-950 nanometers and has been the standard for remote controls since the 1980s. While considered "old technology" by some, IR remains remarkably reliable and energy-efficient.

How to Check if Your Phone Has an IR Blaster

Look for a small dark window or dot at the top of your phone. Common brands that included IR blasters:

According to mobile hardware statistics, approximately 17% of Android phones in circulation still feature IR blaster hardware, though the feature has been phased out of most flagship models after 2018.

Setting Up an IR Remote App

If your phone has an IR blaster, follow these steps:

1. Download an IR remote app from Google Play Store. Recommended options include:

   • IR Universal Remote (4.3/5 stars, 10M+ downloads)
   • ZaZa Remote (4.1/5 stars, 5M+ downloads)
   • Smart IR Remote (4.4/5 stars, 1M+ downloads)
   • ASmart Remote IR (4.2/5 stars, 5M+ downloads)

2. Open the app and select "TV" from the device category

3. Choose "LG" as the manufacturer

4. Follow the on-screen instructions to test different remote codes

5. Once you find a working code, save it for future use

The setup process usually takes less than two minutes. You‘ll have access to all basic TV functions including power, volume, input selection, and channel control.

IR Blaster App Success Rates with LG TVs

Based on aggregated user reviews and technical forums, here‘s the compatibility success rate of IR blaster apps with different LG TV generations:
