Both televisions work perfectly, but each comes with a different remote control. One remote disappears between the couch cushions, while the other constantly needs new batteries.

Wouldn't it be easier to control both TVs using your iPhone?

The good news is that it's possible in many cases.

Modern smartphone remote applications can communicate with compatible smart TVs over Wi-Fi, allowing you to control multiple televisions without switching between physical remotes.

However, Samsung and Insignia televisions don't always use the same operating system or connection technology.

That means the right setup depends on your TV models, network configuration, and the features supported by your remote application.

This guide explains how to use one phone to control Samsung and Insignia TVs, what to check before installing an app, and how to solve common connection problems.

Can You Control Two Different TV Brands With One Phone?

Yes, you can control multiple TV brands with one smartphone if your remote application supports each television's operating system and connection method.

Many universal remote applications are designed to work with several smart TV platforms.

For example, one application might support Samsung Smart TVs, Roku-powered televisions, and Amazon Fire TV devices.

However, compatibility with a brand doesn't guarantee compatibility with every model produced by that manufacturer.

Samsung televisions generally use Samsung's own smart TV software, while Insignia televisions may use Fire TV, Roku TV, or other platforms depending on the model.

A remote app that works with a Samsung Smart TV may not automatically support an Insignia Fire TV.

Before setting up a universal remote, identify the operating system used by each television.

This simple step can save considerable troubleshooting time.

1. Identify Your Samsung and Insignia TV Models

Start by checking the model information for both televisions.

The model number can usually be found in the TV's settings menu or on a label attached to the device.

For Samsung Smart TVs

Look for the model number in the television's support or device information settings.

Samsung Smart TVs commonly use the Tizen platform, although the available remote-control features vary by model and software version.

Some Samsung televisions support smartphone control through Samsung SmartThings.

Third-party remote applications may also support compatible models.

For Insignia TVs

Identify whether your television uses Fire TV, Roku TV, or another operating system.

This matters because the software platform often determines which smartphone remote can connect.

For example, an Insignia Fire TV may work with remote applications supporting Fire TV devices, while an Insignia Roku TV requires Roku-compatible functionality.

If you're unsure which platform your television uses, check its home screen, device information, or original product documentation.

2. Connect Both TVs and Your Phone to the Same Network

Most Wi-Fi-based remote applications need access to the same local network as the television being controlled.

This allows the smartphone to discover compatible devices and send remote commands.

Recommended setup

1. Turn on your Samsung and Insignia TVs.

2. Connect both televisions to your home network.

3. Open Wi-Fi settings on your iPhone.

4. Connect the iPhone to the same local network.

5. Open your chosen remote application.

6. Allow local network access if iOS requests permission.

7. Search for compatible televisions.

Your devices don't necessarily need to use the same Wi-Fi frequency band.

For example, a Samsung TV connected through 5 GHz Wi-Fi and an Insignia TV connected through 2.4 GHz may still communicate with your phone if the router places them on the same local network and permits device discovery.

Avoid isolated guest networks when setting up a Wi-Fi remote.

If your application cannot detect either television, check the router and local network permissions before reinstalling the app.

3. Set Up Your Samsung TV With a Smartphone Remote

Samsung Smart TVs offer several smartphone-control possibilities depending on the model.

Samsung SmartThings is the manufacturer's official smart-home platform and provides mobile remote functionality for compatible televisions.

Some third-party applications can also communicate with supported Samsung TVs.

General setup steps

First, turn on your Samsung Smart TV and confirm that it's connected to your network.

Next, open your remote application on the iPhone.

Search for available devices and select the Samsung television if it appears.

Some TV models may display a connection approval request.

Follow the instructions on the TV screen to authorize the connection.

Once paired, test the navigation and volume controls.

If the connection succeeds but certain buttons don't respond, check whether those features are supported by your particular model.

For additional guidance on compatibility, setup methods, and common connection issues, explore this samsung tv remote app guide.

What about turning the TV on?

Power controls can behave differently from navigation and volume commands.

Some Samsung televisions support network-based wake functions, while others may become unreachable when fully powered off.

Whether your phone can turn on the TV depends on the model, power settings, and remote application's capabilities.

4. Set Up an Insignia TV Remote on Your iPhone

Insignia TVs require a slightly different approach because the brand includes televisions built around different smart TV platforms.

The correct remote-control method depends on which system your television uses.

Insignia Fire TV models

If your Insignia television uses Fire TV, look for a remote application that supports Fire TV devices.

The official Amazon Fire TV mobile app is one possible option for compatible models.

Connect your phone and television to the appropriate local network.

Open the application and follow its device-discovery and pairing instructions.

Some setups may require entering a code displayed on the television.

Insignia Roku TV models

If your Insignia television uses Roku TV, a Roku-compatible remote application is generally the appropriate choice.

The official Roku mobile app supports remote-control functions on compatible Roku devices.

Follow the app's instructions to connect and pair with your television.

Other Insignia models

Not every Insignia television supports smartphone control over Wi-Fi.

Older or non-smart models may require an infrared remote or another compatible control device.

For model-specific setup instructions, check this insignia tv remote app resource before selecting an application.

The important point is to match the remote application to the TV's actual operating system rather than relying on the brand name alone.

5. How to Switch Between Samsung and Insignia TVs

After connecting both televisions, the next step is managing them inside your remote application.

Some universal remote applications maintain a list of previously connected devices.

If your chosen app supports this feature, you may be able to switch between televisions without repeating the entire setup process.

A simple workflow

Open the remote application.

Locate the connected-device list or TV selection menu.

Choose your Samsung television when you're in the living room.

Use the available navigation, playback, and volume controls.

When you move to another room, open the device list again and select your Insignia TV.

The exact steps depend on the application.

Some apps save paired televisions, while others may require you to search for the device again.

If your app supports renaming devices, use recognizable labels such as "Living Room Samsung" and "Bedroom Insignia."

This can help prevent accidentally controlling the wrong television.

6. Choosing a Universal Remote App for iPhone

If you want to control multiple televisions through one interface, a third-party universal remote may be worth considering.

However, don't choose an application based only on the number of brands mentioned in its description.

Instead, check whether it supports the specific TV platforms in your home.

Features worth checking

Multi-brand compatibility: Does the app support your Samsung model and the platform used by your Insignia TV?

Device discovery: Can it find compatible televisions through your local network?

Remote controls: Does it offer the navigation, volume, playback, and menu functions you need?

Device switching: Can you conveniently move between connected televisions?

Pricing: Are the features you want free, or do they require a subscription?

Privacy and permissions: Does the application explain the permissions needed for device discovery and control?

For iPhone users exploring a multi-brand option, you can download tv remote control app from the App Store.

The linked Universal Remote TV Control application lists support for several smart TV platforms, including Samsung, Roku, and Fire TV.

Because Insignia TVs may use Roku TV or Fire TV, compatibility is possible for supported models, but it should be confirmed before relying on the application.

This is a third-party application, not an official Samsung, Roku, Amazon, or Insignia product.

7. What If Your Phone Finds One TV but Not the Other?

One common issue occurs when your iPhone successfully connects to your Samsung TV but cannot detect your Insignia television.

The reverse can also happen.

This doesn't necessarily mean the universal remote application is broken.

Different televisions may have different network settings, supported control protocols, or pairing requirements.

Check the missing television's network connection

Confirm that the television is powered on and connected to your home network.

Try opening a streaming application on the TV to verify its connectivity.

Verify platform compatibility

If the missing device is an Insignia Fire TV, confirm that your remote application supports Fire TV.

If it's an Insignia Roku TV, check for Roku compatibility.

Review local network permissions

On iPhone, open Settings, then Privacy & Security, and check Local Network permissions for the remote application.

Restart the devices

Restart the affected TV and your smartphone.

If necessary, restart your router and reconnect the devices.

Repeat pairing

Remove the saved device connection if the app allows it.

Search for the television again and complete any required authorization.

If the application consistently finds one TV but never detects the other, the missing model may not support that app's connection method.

8. Can You Control Both TVs Without Wi-Fi?

Wi-Fi is the most common connection method for smartphone-based smart TV remotes, but it's not the only technology used by television remotes.

Traditional physical remotes often use infrared signals.

Some televisions also support Bluetooth-based controls.

However, most modern iPhones don't have a built-in infrared transmitter for directly replacing a traditional IR television remote.

That means an ordinary iPhone app cannot automatically control every non-smart TV without additional compatible hardware.

If your television doesn't support network-based control, you may need a physical universal remote or a compatible external IR control device.

Before purchasing extra equipment, verify that it supports your television model.
