The modern smartphone has long ceased to be just a means of communication, having turned into a universal control center for the digital ecosystem of the home. One of the most requested features is the ability to replace a lost or broken remote control for your TV. Owners of brand equipment DEXP often wonder how to download the corresponding application for free and quickly to a phone running Androidin order to regain control over the device.
The process of turning a gadget into a remote control depends on the technical content of your smartphone and the model of the TV. There are two main ways to implement this task: using the built-in infrared port (IR port) or connecting via a local network Wi-Fi. Each method has its advantages, limitations and requires the installation of specific software, which can be found in the official store Google Play without any financial costs.
In this article we will analyze in detail the algorithms for both scenarios, provide a list of proven apps and answer frequently asked questions that arise when synchronizing devices. You will learn how to set up a universal remote control if standard methods do not work, and what nuances should be taken into account when controlling equipment DEXP via a mobile device.
Checking the hardware compatibility of a smartphone
Before you start downloading applications, you need to determine exactly what type of signal transmission your phone supports. The choice of software and configuration method directly depends on this. Most modern flagship and mid-budget models have lost the built-in infrared emitter, relying exclusively on wireless networks.
The presence of IR ports (Infrared Blaster) allows the smartphone to emulate the signal of a regular remote control, working even with the TV turned off (for the turn-on function). To check the presence of this module, carefully inspect the upper end of the device case: there should be a small dark window, similar to a proximity sensor, but located separately. You can also use the technical specifications on the manufacturer's website or specialized scanner applications.
If there is no infrared port, the only working option is control via Wi-Fi. In this case, both the TV and the smartphone must be connected to the same wireless network. This method often provides advanced functionality, including voice control, using a touchpad, and entering text from the phone keyboard, but requires that the TV is already turned on and connected to the router.
⚠️ Attention: Not all TV models DEXP have a built-in Wi-Fi module. Budget series may only support a cable connection or require the purchase of an external set-top box Android TV Box to work with network applications.
You can use system information to accurately diagnose the characteristics of your device. Go to the menu Settings → About phone → Characteristics and look for a mention of IR Blaster or Infrared. If there is no such information, most likely your smartphone relies on network protocols.
Applications for control via IR port
If your smartphone is equipped with an infrared emitter, you gain independence from Internet connections and routers. The operating principle of such applications is to send code sequences identical to those generated by the standard remote control. For TVs DEXP universal apps are suitable, having in their database thousands of profiles for various equipment.
One of the most popular solutions is the application Peel Remote or Mi Remote (for smartphone owners Xiaomi, but it works on other devices with rights or modifications). These apps automatically determine the TV model by sending out test signals. You will need to select the manufacturer DEXP from the list and successively press the buttons on the screen, confirming the TV's response.
The setup process usually looks like this: after launching the application, select the device category (TV), then the brand. Next, a test button appears on the screen, for example, “On/Off” or “Volume+”. If the TV responds, you confirm the action. If not, the application switches to the next code from the database.
- 📱 Versatility: One application can control a TV, air conditioner, projector and audio system simultaneously.
- 🔋 Energy efficiency: The IR port consumes a minimal amount of battery power compared to a constantly active Wi-Fi module.
- 📶 Independence: Works even when there is no electricity in the house (if the TV has a standby mode) and without access to the Internet.
Walls and obstacles block infrared radiation, unlike Wi-Fi radio waves.
If the standard application from the smartphone manufacturer does not find the DEXP brand, try selecting "Generic" or "Universal" from the list of manufacturers, and then going through the codes manually until a reaction appears.
Setting up control via a Wi-Fi network
For modern smartphones without an IR port, using Wi-Fi is the only way to turn the device into a remote control. This method requires that the TV DEXP is connected to the same local network as the phone. The data transfer protocol in this case can be based on standards DLNA, Google Cast or proprietary solutions of the manufacturer.
The first step is to make sure that the network control function is activated on the TV itself. Go to the TV menu through the physical buttons on the body, go to the Network or Settings section and make sure that the "Remote Control" or "Mobile Connect" option is enabled. Without this step, the application on the phone will not be able to detect the device on the network.
There are many free applications, such as TV Remote Control Universal, Sure Universal Remote or official utilities from DEXP (if available in your region). After installation, the application scans the network and displays a list of available devices. When you select your TV, a pairing confirmation request may appear on the TV screen, which you must accept.
⚠️ Attention: If your router has the AP Isolation function, devices on the network will not see each other. For the remote control to work, this function must be disabled in the router settings.
The advantage of Wi-Fi control is the ability to use a smartphone as a touchpad. You can move your finger across the phone screen, moving the cursor on the TV screen, which is much more convenient than button controls when surfing the browser or selecting content in the Smart TV menu.
☑️ Preparing for a Wi-Fi connection
Comparison of popular applications for Android
There are a huge number of apps on the market that claim to title of the best universal remote control. However, not all of them work equally well with brand equipment DEXP. Some applications are overloaded with advertising, others have outdated code bases, and others require a paid subscription for basic functions.
For ease of choice, we analyzed several key parameters of popular solutions. It is important to pay attention not only to the app store rating, but also to the date the device profile database was last updated. The more recent the update, the higher the likelihood that the list already contains current TV models.
Below is a comparative table of the main characteristics of popular applications available for free download. Please note the availability of Russian language support and the type of equipment required.
| Application name | Connection type | Advertising availability | DEXP support | Additional. functions |
|---|---|---|---|---|
| Peel Smart Remote | IR port / Wi-Fi | Minimum | High | TV app |
| TV Remote Control | Wi-Fi only | Yes (banners) | Medium | Voice input |
| Universal TV Remote | IR port | Absent | High | Macros commands |
| Google TV (formerly Play Movies) | Wi-Fi (Chromecast) | No | Depends on TV OS | Content aggregator |
When choosing, it is worth considering that applications with IR port support often have a simpler interface, since they only broadcast button presses. Network applications, on the contrary, strive to create a full-fledged management interface with channel previews and a media library.
Why are some applications paid?
Developers of paid versions offer extended code bases, no advertising and priority technical support. However, for basic volume and channel control, free versions are usually sufficient.
Solving problems with connection and response
Even with proper configuration, users may encounter a situation where the phone does not see the TV or commands are not executed. One of the common reasons is the incorrect operation of the firewall or firewall on the router, which blocks local requests between devices.
If you are using an infrared port, the problem may lie in a physical obstacle or a low smartphone battery. Some phone models automatically turn off the IR emitter when the battery charge is below 10-15% to save energy. In this case, you need to recharge the device.
In the case of a Wi-Fi connection, try rebooting both devices. Unplug the TV for 30 seconds, restart your smartphone and router. This often resets network caches and allows devices to rediscover each other. Also make sure that the "Guest Network" mode is not activated on the TV, which limits access to local resources.
- 🔄 Restart: Completely de-energizing the TV helps reset a frozen network module.
- 📡 Wi-Fi frequency: Make sure that both devices are connected to the same frequency (2.4 GHz or 5 GHz), although modern routers usually combine them into one network.
- 🛡️ Antivirus: Temporarily disable third-party antivirus apps on your smartphone that can block network activity of applications.
If none of the methods does not help, perhaps your TV model DEXP uses a unique signal encryption protocol that is not supported by universal applications. In this case, it is worth looking for a specialized application specifically for your series of TVs.
90% of connection problems are solved by simply rebooting the router and checking that the phone and TV are on the same subnet.
Alternative ways to control equipment
If you cannot download the remote control to your phone or the functionality of the application you are not satisfied, there are alternative options for regaining control of the TV. Modern TVs DEXP often support control through voice assistants, such as Alice or Google Assistant, if you have a compatible set-top box or built-in module.
You can also consider purchasing a universal IR remote control with learning support. Such devices allow you to “copy” signals from the old remote control (if it partially works) or enter the manufacturer’s code manually. This is a reliable hardware solution that does not depend on the smartphone's battery charge or operating system failures Android.
For advanced users, a configuration method is available via a computer using Android emulators, although this is redundant for the simple task of changing the channel. A more rational step would be to use a physical keyboard and mouse connected to the USB port of the TV, which allows you to easily navigate the Smart TV menu without a remote control.
⚠️ Attention: Application interfaces and menu names on TVs may differ depending on the firmware version. If you do not find the item you need, check the official instructions for your specific TV model.
Remember that using third-party applications always carries minimal security risks. Download apps only from a trusted source Google Play and carefully read the permissions that the application requests during installation.
Is it possible to control a DEXP TV without the Internet?
Yes, this is only possible if your smartphone has a built-in IR port. Applications that use infrared radiation do not require an Internet connection to transmit commands, since the signal goes directly from the phone to the TV receiver.
Why does the application not find my TV via Wi-Fi?
The most likely reason is that the devices are connected to different networks (for example, the phone is connected to the mobile data or a guest network, and the TV is connected to the main one). The problem may also be in the router settings that block local interaction between devices.
Is it safe to give an application access to the microphone?
Access to the microphone is only necessary if you plan to use the voice control function. This access is not required for normal operation of the remote control buttons. If an application requests it without a clear need, this is a reason to think about its reliability.
Is the remote control for DEXP suitable for other brands?
Universal applications contain code bases for hundreds of manufacturers. There is a high probability that the configured profile will also be able to control equipment from brands BBK, Harper or DEXP, since they often use similar OEM platforms.
What to do if the phone does not have an IR port?
You will need to use applications that work over Wi-Fi. If your TV does not support Smart TV or network connection, the only option is to buy an external IR transmitter that connects to the headphone or USB jack of a smartphone, or to buy a regular universal remote control.
