I'm sure you've been there more than once: you've flopped down on the sofa, found the perfect position under the blanket, and then, when you go to press play… The TV remote has disappearedIt's either at the other end of the room, or it's tucked away between the cushions, or it's simply run out of batteries at the worst possible moment. The good news is that these days that doesn't have to be a big deal.
Your mobile phone, that device you always carry with you and that already acts as a camera, calendar, navigator, wallet, and even a flashlight, can also become a universal remote control for television and other devices in the living room. And no, it's not science fiction: with the right apps and connection, you can retire (or at least relegate to the background) the classic remote control.
From watch-remote to rugged mobile phone: why use your smartphone as a remote control
Years ago, some became fashionable watches capable of changing channels and increasing the volumeThese were real geeky gadgets that many now keep as collector's items. That was the beginning, but now the real star is the mobile phone, which has transformed into a kind of technological swiss army knife for everyday use, and you can also Turn your smartwatch and mobile phone into a remote control.
Using your mobile phone as a controller has several clear advantages: to begin with, You always have it on handUnlike the original remote, which seems to have a mind of its own and disappears every other minute, many remote control apps offer [these features]. more functions than the physical controller, such as screencasting, mirroring your mobile screen on the TV, or controlling other connected devices like sound bars, projectors, or even some household appliances.
There is also an economic reason: a quality physical universal remote control It can be quite expensive, while most apps to turn your mobile into a controller They are free or cost less than 10 eurosThis makes the price-quality ratio very attractive, especially if you have several devices at home.
And if that weren't enough, in terms of convenience, the smartphone allows you centralize control of the houseFrom a single screen you can change channels, adjust the volume, pause a series, turn on the air conditioning, or control smart lights and speakers, depending on the devices you have connected and the apps you use.
How does a mobile phone work as a universal remote control: infrared and WiFi?
Before you start downloading apps willy-nilly, it's worth understanding How does the mobile phone communicate with the TV or device?It's not magic; it's technology you already know, but combined with the right apps, it allows your smartphone to become a true universal remote.
In practice, current mobile phones can control other equipment in two main ways: using an infrared (IR) sensor, like the one used by traditional controllers, or through the network connection (WiFi or Bluetooth) taking advantage of the fact that many televisions and devices are now smart and connect to the Internet.
Option 1: Use your mobile phone as a remote control with an infrared sensor
Some Android phones still include a integrated infrared port or emitterThis sensor is usually located on the top edge of the device. It allows the phone to emit the same signal as a traditional remote control, making it ideal for controlling various functions. older TVs, air conditioners, DVD players and other devices that operate with a classic IR remote control.
The first step is Check if your phone actually has this sensor.. To find out, you can Consult the technical specifications on the manufacturer's website.You can search for the model on Google or physically check if there's a small dark window at the top. Another very practical option is to directly install a universal remote control app compatible with infrared: if your phone doesn't have IR, the app itself will notify you and It will not let you continue with the setup..
Among the best-known apps for using the IR port is Mi Remote (also called My Remote controller), which usually comes pre-installed on many Xiaomi phones and is available for free on Google Play. Once installed, the app asks you to choose what type of device do you want to control: television, DVD, soundbar, projector, air conditioning and a long etcetera.
Once you select the type of appliance, the next step is to indicate the specific brand of the deviceThe app will show you different control configurations to test (for example, by pressing the power or volume buttons). When it works, you can name it, save it, and keep it. always at hand as if it were a dedicated controllerThe mobile phone will display a design similar to a traditional remote control, with buttons for volume up and down, changing channels, muting, going to the previous or next track, etc.
The great advantage of these IR apps is that you can Register as many devices as you want, without limit.: several TVs, the air conditioning in the living room and bedroom, the DVD player, the soundbar… All grouped into the same phone, ready to use and without having a drawer full of different remotes that nobody knows which is which.
However, not all mobile phones include this sensor yet. iPhones, for example, do not have infrared. And many recent Android models have also done away with it to save internal space. Therefore, although the IR option is very convenient if your phone supports it, WiFi and Bluetooth connections are increasingly used to turn your phone into a universal remote.
Option 2: Turn your mobile phone into a remote control using WiFi or Bluetooth
The second way, and the most common in current televisions and devices, consists of taking advantage of the network connectivitySmart TVs and many modern devices can connect to the Internet, either by cable or WiFi, and this makes it possible for your mobile phone to communicate with them. through the same home network.
For this form of control to work, two basic requirements must be met: firstly, that the TV or device is compatible with app control (most current Smart TVs are), and on the other hand, that Both the smartphone and the TV are connected to the same WiFi networkIf the phone is on mobile data or another network, the app probably won't detect the device.
Once the connection is established, you just need to install the appropriate application. Here are two main families of apps: on the one hand, the universal remote control applications that work with many brands; on the other hand, the official apps from each manufacturerwhich usually offer the best compatibility with their own TV models and devices.
Universal apps to control your TV from your mobile phone
Within the group of universal apps, the category of apps that turn your mobile phone into a remote control for virtually any TV stands out, whether it's a Smart TV or even older models with IR support. A good example is... UniMote – Universal Remote Control for all TVs, very popular on Android.
UniMote lets you use your mobile phone as a Remote control for Smart TVs from brands such as Samsung, LG, Sony, Hisense, TCL, Roku, Vizio, Insignia And many more, as long as the TV is connected to the same Wi-Fi network as the phone. Furthermore, if your Android phone has infrared, you can also control it. non-Smart TVs using the IR blasterwhich covers both modern equipment and older models.
Beyond the volume up and channel change buttons, these apps usually offer interesting extra features How to mirror your mobile screen on the TV (screen mirroring), send videos and photos to the TV (screencast or smart sharing), or even control devices like Chromecast, Fire TV Stick or Roku Stick from a mobile-adapted interface.
The appeal of UniMote and similar systems is that they replicate a Handling very similar to the original controllerBut with a modern, touch-sensitive interface. You can customize certain aspects, have everything in a single app, and, incidentally, save on batteriesbecause the only energy consumption will be that of the phone's battery.
Other universal apps widely used on Android to turn your mobile phone into a controller are Peel Smart Remotewhich was one of the pioneers in this field and has a huge catalog of compatible devices, and other solutions that combine content guidance with remote control. In all cases, the philosophy is the same: a single remote control on your phone for multiple brands and models.
Official apps from Smart TV manufacturers
When it comes to ensuring compatibility, the most sensible thing to do is often to opt for the official apps for each TV brandManufacturers such as Samsung, LG, Sony, and Philips offer their own apps in app stores that allow you to control the main functions of their Smart TVs from your mobile phone.
Widespread examples are Samsung SmartThings for Samsung TVs and devices, or LG ThinQ for the LG ecosystem. These apps automatically detect TVs connected to the same Wi-Fi network and allow turn the TV on and off, change channels, adjust the volume, change the input source, type text from the mobile keyboard and even integrate the television into connected home systems.
In the case of televisions with Android TV or Google TVGoogle offers its own remote control solution through the official app, formerly called Android TV Remote Service, which is now integrated into the Google Home app and the operating system of some Android phones. With it you can manage any device with Android TVregardless of the manufacturer, as long as it is connected to the same network.
The main advantage of official apps is that, being designed by the manufacturer itself, they usually offer near-perfect compatibility with the specific functions of each TV: shortcuts to access its services, dedicated buttons for streaming platforms, integration with voice assistants, and optimized updates when the TV system is renewed.
Control your TV with Google Home and other smart home apps
Beyond pure and simple control apps, there are applications that turn your mobile phone into whole home control centerincluding television and other multimedia devices. One of the best known is Google Homewhich integrates especially well with TVs with Chromecast built-in, external Chromecast devices, smart speakers, and other connected equipment.
With Google Home you can Turn on the TV, play content, pause, raise or lower the volume and even change the playback source using your phone or voice, if you have speakers with Google Assistant. The interesting thing is that, in addition to the TV, you can manage lights, smart plugs, thermostats, and robot vacuums all in the same app, making your smartphone becomes a kind of master control of the house.
This approach is complemented very well by voice assistants: if you set up Alexa, Google Assistant, or Siri with your devices, you can combine voice control with touch control from mobile appsachieving a fairly comfortable and flexible experience for everyday life in the salon.
Using an Android device as a universal remote: infrared, WiFi, and recommended apps
In the case of Android, the range of possibilities is especially broad because Some phones include infrared, and all have WiFi and Bluetooth.This allows you to use both the IR option for older TVs and network control for modern Smart TVs.
If your phone has an IR sensor, apps like Mi Remote or some pre-installed apps from manufacturers (especially Asian brands) let you control televisions, air conditioners, projectors, sound bars and other devices with a guided and fairly simple setup process. You just choose the type of device, the brand, and keep testing until it responds.
For Smart TVs and connected devices, you can opt for universal apps like UniMote, for classic solutions such as Peel Smart Remoteor through brand-specific apps (Samsung SmartThings, LG ThinQ, Sony apps, Philips, TCL, Roku, etc.). Almost all of them work under the same logic: to ensure that mobile and TV share the same WiFi network, find the TV and link it with a couple of taps.
In addition, many of these apps include features for screen mirroring and screencastThese apps allow you to mirror your phone's screen or send videos, photos, and music directly to your TV. It's a very practical way to show travel photos on the living room TV without having to pass your phone around.
However, if you want to use your mobile phone as a remote control for a television that only supports infrared, it is essential that the phone has integrated IR blasterSimply installing an app is not enough: if the hardware is not present, the mobile phone cannot emit the same signal as a physical controller, no matter how hard the software tries.
Using an iPhone as a TV remote control
In Apple's territory, things are somewhat different because No iPhone incorporates an infrared sensorThis means you won't be able to directly control older TVs with just your phone, unless you use external accessories that add IR (something increasingly rare). The natural way to use an iPhone as a remote is, therefore, via the internet.
For compatible Smart TVs, the key is to use official manufacturer apps or third-party applications that work with your specific model. For example, LG offers its own app for iOS, and there are apps like myTifi that allow you to control certain brands and ranges of televisions via WiFi.
Furthermore, the Apple ecosystem has the advantage of Apple TV and AirPlayIf you use an Apple TV or an AirPlay 2-compatible TV, your iPhone can function as a remote control using the Apple TV Remote app built into the system. You'll be able to manage menus, play content, type with the mobile keyboard and even use the iPhone for simple games, all through the network connection.
Just like on Android, you can also use Google Home or other smart home apps that are available on iOS to control compatible Chromecast devices, speakers, and Smart TVs. The principle is the same: the iPhone acts as a control center while All devices are connected to the same WiFi network.
