How to Turn Your Android Phone Into a Backup TV Remote When the Original Is Broken or Lost

The TV remote is the most frequently lost and hardest-to-find object in any household. It can slip between sofa cushions, fall behind the TV stand, or mysteriously migrate to the bathroom for no clear reason. And strangely, it always disappears right when you want to watch something. If you find yourself in this situation, don't panic. The Android phone already in your hand can transform into an emergency TV remote in under two minutes.

There are two main paths you can take, depending on the type of TV and phone you have. The first is through the official app from your TV manufacturer. The second takes advantage of the infrared sensor (IR Blaster) that may be built into your phone. Each has its advantages and limitations, and I'll walk through both with easy-to-follow steps.

Path one: Official TV manufacturer apps

Almost all modern smart TVs have an official remote app available for download on the Play Store. Samsung has SmartThings. LG has LG ThinQ. Sony has Video & TV SideView. Xiaomi and other Android TVs can use the Android TV Remote Control app directly from Google. These apps don't require infrared. They work through the same WiFi connection as your TV.

Using them is straightforward. Make sure both your phone and TV are connected to the same WiFi network. Download the official app that matches your TV brand. Open the app, and typically your TV will be detected automatically. Some apps will ask you to enter a code displayed on the TV screen for verification. Once connected, your phone will display a full remote interface with navigation buttons, volume control, and even a keyboard for typing. Some apps even have features more advanced than the physical remote, like voice input and a touchpad.

📱 Advantages of official apps: No infrared needed. You can type using your phone's keyboard, which is much faster than pecking out one letter at a time with navigation buttons on a regular remote. Some apps can even turn on the TV as long as it's in standby mode and connected to WiFi.

Path two: Using the IR Blaster on your Android phone

Not all Android phones have an IR Blaster, but if yours does, you're in luck. An IR Blaster is a small component at the top of the phone that can send infrared signals, exactly like a regular TV remote. Brands like Xiaomi, Redmi, Huawei, and some older Samsung models often include this feature. The easiest way to check is to see if there's a small hole or glossy black dot at the top edge of your phone. Or even simpler, search "IR Blaster" on Google along with your phone model.

To use it, you'll need a universal remote app. There are plenty of options on the Play Store, and some of the most popular ones are Mi Remote (for Xiaomi), ZaZa Remote, or Lean Remote. These apps have a database of infrared codes for thousands of TV, AC, fan, and even projector brands. The steps: download the app, select the "TV" category, choose your TV brand, then point your phone at the TV and press the power button. The app will cycle through various codes until the TV responds. Once the TV turns on or off, save that code and your virtual remote is ready to use.

🔧 Quick IR Blaster check: Open your phone's camera app. Point your physical TV remote at the camera and press any button. If you see a purple or pink light flashing on the camera screen, that's an infrared signal. Now try the same thing with your phone using a remote app. If you see a similar flash, your IR Blaster is working.

What if your TV isn't a smart TV?

Older or non-smart TVs can usually only be controlled via infrared. If your phone doesn't have an IR Blaster, official apps won't work because these TVs lack WiFi connectivity. But don't lose hope just yet. There's a small device called an external IR blaster that can plug into your phone's USB-C port or headphone jack. It's very inexpensive, costing just a few dollars. This gadget adds infrared capability to phones that don't have it built in.

Another alternative that's gaining popularity is a smart IR blaster that connects via WiFi, like BroadLink or Tuya Smart. This device sits in the same room as your TV and acts as a bridge between your phone and the TV. The added benefit is that besides your TV, you can also control your AC and other infrared devices from a single app, even from outside your home.

💡 Important tip: Some Android TVs, especially from brands like TCL, Hisense, or Coocaa, sometimes aren't automatically detected by the official Google app. Try searching for a brand-specific remote app on the Play Store. Almost every TV manufacturer now has its own remote app.

Limitations you should know about

A phone remote won't completely replace a physical remote. There may be some buttons that aren't available in the app, like dedicated menu buttons or shortcut keys to specific apps. Additionally, if the TV is completely powered off and disconnected from electricity, some TVs still need to be turned on first using the physical button on the TV body before they can be recognized by the app over WiFi.

But for emergency situations—the physical remote is lost, the remote batteries die in the middle of the night, or the volume button gets stuck—an Android phone is a nearly perfect lifesaver. It's always near you, doesn't need to be searched for between sofa cushions, and as long as your phone battery is alive, that remote will never run out of power. Save this article. One night, you might be very glad you found it.
