Using your cell phone as a remote control – how it works
Cell phones have long been more than just communication devices. They serve as cameras, navigation aids, game consoles – and even remote controls. Whether you want to turn on the TV, adjust the music volume, or dim the lights, you can do it all easily with your smartphone.
We'll show you how to turn your cell phone into a versatile remote control – from your TV to your smart home system.
Your cell phone as a remote control – here are the options
Smartphones can be turned into remote controls in a variety of ways, depending on the device, technology, and personal preference. But not every method is suitable for every purpose.
In this section, you'll learn about the technical options available, the requirements that need to be met, and why your cell phone can be a smart solution as a universal remote control.
Infrared vs. Wi-Fi: What you need
There are two main technologies that allow you to operate remote controls via your cell phone: infrared (IR) and Wi-Fi/Bluetooth.
Infrared: Works similarly to classic remote controls. Some smartphones – especially those from Asia, such as Xiaomi or Huawei – have an integrated IR blaster. This allows many older devices to be controlled without an internet connection.
Wi-Fi/Bluetooth: This method is standard on modern devices. It requires that the mobile phone and end device are on the same network. Many smart TVs, streaming boxes, and smart home systems rely on Wi-Fi or Bluetooth for control via apps.
Requirements depending on device and manufacturer
Certain conditions must be met for everything to work:
- Device must be app-compatible: Not every TV or system can be controlled via an app. Check whether your device supports this function.
- Shared network: Your mobile phone and the device you want to control must be connected to the same Wi-Fi network.
- Up-to-date software: The software on both your mobile phone and the device you want to control should be up to date.
Advantages: One remote control for everything
With your smartphone as a universal remote control, you have everything in one place. No more searching for the right remote control! Instead, you can control everything conveniently via the display – often with additional functions such as voice control, touchpad, or program preview. Many apps also offer a better overview and user guidance than conventional remote controls.
Which devices can be controlled with a cell phone?
Not only can you control your TV with your cell phone, but also many other devices in your home:
TVs and set-top boxes: The most common models from Samsung, LG, Sony, Panasonic, and others can be operated via their own or universal apps.
Streaming devices: Amazon Fire TV, Google Chromecast, Apple TV, and Roku offer native apps for control via cell phone.
Smart home components: Lighting systems such as Philips Hue, heating controls (e.g., Tado°, Netatmo), roller shutters, door cameras, and even smart coffee machines can be regulated via an app.
Music systems and speakers: Wi-Fi and Bluetooth systems (e.g., Sonos, Bose, Teufel) respond to commands from your smartphone.
PCs and consoles: With additional apps, you can control your PC or use your Xbox and PlayStation as a media center.
Central control via your smartphone makes your home smarter – and your everyday life more convenient.
Advantages and disadvantages of remote control via mobile phone
As practical as smartphone control is, it does not only have advantages. In addition to the most important advantages, it is therefore also important to mention possible disadvantages or limitations.
Advantages
You only need one device – your mobile phone.
Control is usually more intuitive and flexible.
You have additional features such as timers, routines, and voice control.
Operation also works from a greater distance via Wi-Fi.
Disadvantages:
Battery consumption increases, especially with intensive use.
Some functions are only available with a stable Wi-Fi connection.
A classic remote control is still necessary for incompatible devices.
Data protection concerns cannot be ruled out with cloud-based apps.
Instructions: Using your cell phone as a remote control
Setting up your mobile phone as a remote control is usually quick and easy – provided you know what to do. Here we show you step by step how to set up your smartphone correctly depending on the device and manufacturer, and which apps can help you.
Control your Samsung TV with your mobile phone
Step 1: If you want to use your mobile phone as a Samsung remote control, download the SmartThings app from the Google Play Store or the Apple App Store.
Step 2: Make sure that both your smartphone and the Samsung TV are connected to the same Wi-Fi network.
Step 3: Open the app, tap on “Add device” and select your TV from the list.
Step 4: Confirm the connection code displayed on the TV.
Now you can change channels, adjust the volume, and even launch apps—all directly from your smartphone.
LG, Sony, and others
Other manufacturers also offer their own mobile phone remote control apps:
LG ThinQ: For LG TVs manufactured in 2018 or later with webOS.
Sony TV SideView: Particularly useful for Sony Bravia models.
Panasonic TV Remote: Supports many models from 2012 onwards.
Setup and operation are usually similar: install the app, connect to Wi-Fi, select the device, pair – done.
Universal remote control apps
If you control many different devices or don't want to use a manufacturer-specific app, universal apps such as these are a good option:
Sure Universal Remote: Supports IR and Wi-Fi, very user-friendly.
Mi Remote (Xiaomi): Works well with many TV and audio devices.
Unified Remote: Particularly suitable for controlling PCs and laptops.
These apps are often free, but offer advanced features in a premium version.
Don't forget security and data protection
Despite all the convenience, using remote control apps also comes with risks. If you want to control your TV with your cell phone, keep the following points in mind:
Grant app permissions carefully: A remote control app does not necessarily need access to your contacts or your location.
Secure Wi-Fi: Use encryption (WPA2 or WPA3) and change your Wi-Fi password regularly.
Update smart devices regularly: Security vulnerabilities in smart home components can be a gateway for hackers.
Critically review cloud services: Many apps store user data in the cloud – find out where and how it is processed.
Extra tip: Use a separate Wi-Fi guest account for your smart home devices. This will help protect your sensitive data.
Conclusion
Using your cell phone as a remote control is extremely practical. Whether you want to turn on the TV, dim the lights, or start your favorite playlist, with the right app, you have everything under control.
All you need is a little preparation and some technical knowledge. Then nothing stands in the way of digital convenience, and you can control everything via a central, mobile control unit: your smartphone.
