IPTV Smarters Pro on ONN Box — The Easiest Way to Start Streaming in 2026
When someone asks which is the best player for ONN tv box for a user who has never set up a streaming service before, the answer is almost always IPTV Smarters Pro. While TiviMate is more powerful and has a more polished interface, Smarters has one decisive advantage: it is extraordinarily easy to set up. Download, enter your credentials, and you are watching 4K content within five minutes. No advanced configuration, no hunting through settings menus, no EPG URL to track down separately.
IPTV Smarters Pro is developed by WHMCS Smarters and is available completely free on the Google Play Store. It supports both M3U playlist URLs and Xtream Codes API connections — the two most common methods used by streaming services worldwide. When you connect via Xtream Codes, Smarters automatically organizes your channels into categories (Sports, Movies, News, Entertainment), loads all your VOD content, and imports the EPG guide without any manual input required.
For ONN tv box smarters pro users, the experience is particularly smooth on the ONN 4K Pro and Plus because both devices run Google TV with Play Store access, meaning Smarters installs in a single tap. The ONN 4K standard (Android TV) may require sideloading if Smarters does not appear in its Play Store, but the process is simple and takes less than three minutes.
How to Install IPTV Smarters Pro on ONN Box
The installation process for IPTV Smarters on ONN differs slightly depending on which ONN model you have. Here is the complete process for both scenarios.
Method 1: Google Play Store (ONN 4K Pro and Plus — Recommended)
Open Google Play Store on Your ONN Device
From the Google TV home screen, open the Play Store. Ensure you are signed in with a Google account. The Play Store is accessible from the home screen search bar or the dedicated Play Store icon in the apps section.
Search for "IPTV Smarters Pro"
Type IPTV Smarters Pro in the Play Store search. The official app by WHMCS Smarters will appear — it has a green hexagonal icon with a play triangle. Verify you are installing the official app, which has over 10 million downloads. Tap Install.
Open IPTV Smarters Pro
Once installed, open the app. The first screen asks you to accept the terms of service and then presents you with the Add User / Login screen. This is where you will enter your streaming service credentials.
Add Your Playlist via Xtream Codes
Tap Login with Xtream Codes API. Fill in the following fields with the information from your ONN 4K Stream welcome email.
Server URL: (from your welcome email)
Username: (from your welcome email)
Password: (from your welcome email)
Tap "Add User" — Start Streaming
Smarters will connect to the server, load your channel list, VOD library, and EPG guide. This takes 20–60 seconds depending on playlist size. Once loaded, your complete channel library is organized by category and ready to browse.
Method 2: Sideload on ONN 4K Standard (Android TV)
If IPTV Smarters Pro does not appear in the Play Store on your ONN 4K standard (which runs the older Android TV 10), you can install it using the Downloader sideloading method. First, go to Settings → Device Preferences → Security → Unknown Sources and enable it for the Downloader app. Then install Downloader by AFTVnews from the Play Store. Open Downloader, enter the official IPTV Smarters APK download URL from the WHMCS Smarters website, and install. The entire process takes under five minutes.
Best IPTV Smarters Settings for ONN Box — Detailed Explanation
Like TiviMate, IPTV Smarters Pro performs significantly better with the correct settings applied. The defaults are conservative and work across a wide range of devices, but for the specific hardware in ONN devices, targeted adjustments unlock noticeably better performance on 4K content.
Enable ExoPlayer and Hardware Decoding
In Smarters, navigate to Settings → Player Settings → Video Player and select ExoPlayer. Immediately below, find Hardware Decode and toggle it On. This is the most important performance setting for any ONN device. ExoPlayer uses the hardware video decoder built into the ONN processor, which handles 4K streams far more efficiently than software decoding. On the ONN 4K standard with 2 GB of RAM, this setting is essential — without it, high-bitrate 4K channels will stutter or buffer continuously.
Use TV Mode Interface
IPTV Smarters Pro has two interface modes: a standard mobile-style layout and a TV Mode designed specifically for the 10-foot living room experience. Always use TV Mode on your ONN box. It replaces the touch-based mobile interface with a remote-control-friendly layout, larger text, and a navigation system designed around directional buttons. Go to Settings → General → Interface Mode → TV / Leanback Mode.
Set Buffer to 30 Seconds
Navigate to Settings → Player Settings → Buffer Duration and set it to 30 seconds. As with TiviMate, a larger buffer gives Smarters more headroom to absorb brief network interruptions without pausing playback. This is particularly helpful on 4K live channels and sports streams where bitrates can spike unpredictably.
Enable Keep Screen On
In Settings → General, enable Keep Screen On. Without this, the ONN device may dim the screen or trigger its screensaver while streaming is active, which can interrupt playback on some Android TV configurations.
IPTV Smarters vs TiviMate on ONN — Which Should You Use?
The most common question among new ONN box users is whether to use TiviMate or IPTV Smarters Pro. Both are excellent applications that work perfectly with our service. The right choice depends on your priorities.
Choose IPTV Smarters Pro if you are new to streaming, want the fastest possible setup, need multiple user profiles for free, or want catch-up TV without paying for a premium subscription. Choose TiviMate if you want the best possible EPG interface, need recording capability, and are comfortable paying $4.99/year for a significantly more polished experience.
Many experienced ONN 4K Pro users run both applications simultaneously — Smarters as a quick-access option for casual viewing and TiviMate as the primary player for scheduled recordings and EPG browsing. Since both are free (or very low cost), there is no reason not to install both and use whichever suits the moment.
How to Add Multiple Playlists in IPTV Smarters on ONN
One of Smarters' strongest advantages over free TiviMate is its support for multiple user profiles and playlists at no cost. Each profile in Smarters acts as a completely independent user with its own playlist, credentials, and settings. This is extremely useful for households where different family members prefer different content, or for users who maintain backup servers.
To add a second playlist, tap the user icon in the Smarters menu and select Add New User. Enter the credentials for your second provider or backup server following the same Xtream Codes process described in the installation section. Switching between profiles requires only tapping the user icon and selecting the desired account — the transition takes just a few seconds.
Fixing Common IPTV Smarters Issues on ONN Box
While IPTV Smarters Pro is one of the most stable streaming players available, ONN box users occasionally encounter specific issues. Here are the most common problems and their solutions.
Buffering on 4K Channels
Buffering in Smarters on ONN is almost always related to one of three causes: Wi-Fi instability, software decoding being used instead of hardware, or the buffer size being set too low. The three-step fix: connect via Ethernet on the ONN Pro or Plus, enable Hardware Decoding in player settings, and set the buffer duration to 30 seconds. In over 80% of cases, this resolves buffering completely.
Channels Not Loading or Black Screen
If specific channels show a black screen or fail to load in Smarters, the first step is to check whether those channels work in a different player (such as TiviMate or VLC). If they work elsewhere, the issue is a Smarters player configuration — try switching the video player engine in settings. If they don't work in any player, contact ONN 4K Stream support to verify the stream URL for those channels is active and correct.
EPG Guide Not Loading
If the EPG guide shows no programme data after connecting via Xtream Codes, go to Settings → EPG Settings → Force Update EPG. This triggers an immediate reload of all schedule data from the server. If the EPG still does not load, verify that your subscription plan includes EPG access — all ONN 4K Stream plans include a full 7-day EPG at no additional cost.
App Crashes on ONN 4K Standard
The ONN 4K standard has only 2 GB of RAM, and Smarters can crash if too many other apps are running simultaneously or if the app's own cache has become bloated. Fix: go to Settings → Apps → IPTV Smarters Pro → Clear Cache, then restart the app. Also close all background apps before opening Smarters by long-pressing the Home button and clearing the recent apps list.
