This ensures support for modern data transfer protocols, such as Miracast or DLNA, which are critical for stable picture quality.
It's also worth deciding in advance which connection method you need. If you're simply planning to control volume and channel switching, any remote app will do. However, if you're aiming to watch videos from your phone's memory, you'll need technology support. Wi-Fi Direct or the presence of a common router.
Setting up a Wi-Fi connection on a DEXP TV
The first step is always connecting the TV to your home network. Without this basic step, most Smart TV features, including app installation and online streaming, will be unavailable. The process begins by entering the system's main menu.
Using the remote control, press the button Home or Menuto open the Start screen. Find the gear icon representing Settings, usually located in the upper right corner of the interface. From the list that opens, select a section. Network and Internet or simply Net, depending on the firmware version.
Turn on the Wi-Fi slider if it's in the "Off" position. The system will automatically scan for available access points. In the list that appears, find the name of your home network (SSID) and tap it. If the network is hidden, select the option Add a network and enter the name manually.
A virtual keyboard will appear on the screen. This is where things often get tricky, as entering a password using the remote's buttons takes a long time. It's at this point that many users wonder, How to connect a DEXP Smart TV to Wi-Fi from a phoneto simplify input. However, for now we'll consider the standard method.
☑️ Check before connection
After entering the password, click "Connect." The connection status should change to "Connected," and a signal strength icon will appear next to the network name. If the connection fails, check that your keyboard layout (language and capitalization) is correct.
⚠️ Note: If your router broadcasts a 5 GHz network, but your older DEXP TV only supports 2.4 GHz, it simply won't see the network. In this case, you'll need to go to your router settings and enable a guest network or a separate SSID for the 2.4 GHz frequency.
Using your smartphone as a remote control
One of the most popular features is controlling your TV via your smartphone. This is especially convenient when the physical remote is lost, dead, or when you need to enter a complex text query into YouTube search. To use this feature, both devices must be on the same local network.
For Android smartphone owners, the official app is the optimal solution. Google Home or Android TV Remote ControliOS users are advised to pay attention to the application. TV Remote & Universal Controller or specialized utilities from DEXP, if they are available in the App Store.
Install the selected app from the Google Play or App Store. Once launched, the app will automatically scan the network for available TVs. When your DEXP's name appears in the list, select it.
A connection permission prompt will appear on the TV screen, along with a PIN code. Enter this code on the smartphone screen to pair. The phone interface will now transform into a touchpad and keyboard.
What should I do if the app doesn't detect the TV?
Make sure the Android TV Remote Service app is enabled on your TV under "Settings" -> "Apps" -> "System." Also, make sure both devices are connected to the router's primary SSID, not to a guest network with client isolation.
This connection offers a wide range of functionality: you can type text from your phone's keyboard, which is much faster, use voice search through your smartphone's microphone, and even stream audio through headphones connected to your phone so as not to disturb others.
Screen Mirroring
Screen mirroring allows you to display your smartphone's content on a larger display in real time. This is ideal for viewing photos, presentations, or videos that aren't supported by your TV's built-in player. This data transfer technology can be called by various names: Miracast, Wi-Fi Direct, Smart View, or Casting.
On DEXP TVs with Android TV, this feature is often built into the system. You'll need to find the app. Broadcast or Wireless Display in the list of programs and launch it. The screen will go into connection standby mode.
On your Android smartphone, open the notification shade and find the button Broadcast, Smart View or ProjectOn iPhone this feature is called Screen mirroring and requires support for AirPlay technology from the TV (in DEXP this is often implemented through built-in applications such as AirScreen).
After selecting a device from the list, the image will be duplicated on the phone. It's important to understand that with this method, the phone and TV create a direct connection or use the router as a bridge, which can strain the Wi-Fi channel.
⚠️ Please note: When streaming high-definition content (Full HD or 4K), audio lag (desync) may occur. For best sound quality, use built-in apps on your TV rather than streaming from your phone.
Sharing Internet from your phone to your TV
Situations where there's no wired internet and no Wi-Fi router are readily available are common. In such cases, a smartphone can act as a hotspot. However, there's an important technical nuance: the TV must be able to connect to the phone's hotspot just like it would to a regular router.
Turn on the mode on your smartphone Wi-Fi hotspot (Hotspot). In the access point settings, set the network name and password. It is recommended to set the frequency range to 2.4 GHz for maximum compatibility, although modern smartphones and TVs can also operate on 5 GHz.
On your DEXP TV, go to the network settings, find the access point you created (it will have the same name as your phone), and connect by entering the password. Once connected, the TV will access the global network via mobile data.
It's worth considering your mobile data usage. Watching high-quality videos (HD/4K) via streaming services can quickly use up your gigabit data plan. This method is perfectly fine for news apps or low-quality YouTube videos.

To help you organize your information and choose the best option for your needs, check out the comparison chart of smartphone and DEXP TV interaction methods.
| Method | The need for a router | Phone traffic consumption | Main purpose |
|---|---|---|---|
| Remote control app | Yes (public network) | Minimum | Control, text input |
| Screencasting | Preferably (or Wi-Fi Direct) | No (locally) | Show photos and videos from the gallery |
| Access point | No (the phone is like a router) | High | TV Internet access without Wi-Fi |
| Wi-Fi Direct | No | No | File transfer, media |
Solving common connection problems
Even with the correct settings, issues can still occur. One common problem is when the TV sees the network but fails to connect, displaying the error "Obtaining IP address..." or "Authentication error." In the former case, try disabling MAC address filtering in your router settings or expanding the DHCP address pool.
If your DEXP TV can't detect the 5 GHz network, even though your router is broadcasting it, the issue may be with the broadcast channel. Some TV Wi-Fi modules don't support channels higher than 11 or 13. Try setting the channel in your router settings to 1, 6, or 11 for the 2.4 GHz network.
A common obstacle is antivirus software on your router or phone, which blocks local communication between devices. Try temporarily disabling protection or adding devices to your trusted list.
In rare cases, a complete reset of the TV's network settings can help. To do this, go to Settings → System → Reset → Reset network settingsThis will delete all saved Wi-Fi passwords, but often resolves software conflicts.
Frequently Asked Questions (FAQ)
Is it possible to connect a DEXP TV to Wi-Fi without a remote control?
Yes, if you have a USB keyboard or mouse, you can connect them to the TV's USB port. Some models also support HDMI-CEV control if the connected set-top box has a remote. As a last resort, if the TV has already been set up and connected to Wi-Fi, you can use the remote app on your phone, if it was previously linked.
Why doesn't DEXP TV recognize my iPhone for streaming?
DEXP Android TVs do not have native AirPlay support (Apple technology). To connect an iPhone, you need to install an emulator app on the TV, such as AirScreen or AirPin, which are available in the Google Play Store on the TV itself.
How can I improve my TV's Wi-Fi speed if it's located far from my router?
Use a Wi-Fi repeater (signal booster), plugging it into a power outlet midway between the router and TV. Also, change the Wi-Fi channel to a less congested one in the router settings. Ideally, use a wired LAN connection if the distance allows.
Is it safe to enter bank card details on a DEXP TV?
Entering data via the remote's virtual keyboard is less secure than using secure apps on your smartphone. We recommend using linked accounts (e.g., Google Pay, if supported, or linking your card to a Google/Yandex account) or paying for subscriptions via your phone by logging into the TV apps.
