Meet the MAG425A — a Ukrainian-produced STB with 4K capabilities built with high-quality IPTV and VoD multimedia streaming in mind. Android TV, 4K HDR support, and voice-controlled remote control are recognized as the device’s main selling points. In addition, it passed official certification by Google.
At the heart of the STB is a HiSilicon Hi3798M V200 CPU that easily handles high-bitrate video streaming. The MAG425A runs Android TV 8.0 and comes with 2 GB RAM and 8 GB of internal storage. A micro SD card reader and two USB ports (one USB 2.0 and the other USB 3.0) are available to expand storage, too. To hook the STB up to the internet, a built-in Ethernet port or high-speed dual-band 2.4/5 GHz Wi-Fi 801.11 b/g/n/ac module can be used.

MAG425A Set-Top Box Review
The device comes packaged in a shrink-wrapped white cardboard box. Made of soft cardboard, the box has a picture of the STB with a remote, as well as the specs printed on it.
Every accessory in the box is packaged in a polyethylene bag. The packaging looks reliable overall and is attractive enough to make a good gift.

MAG425A Set-Top Box Remote Control
MAG425A ships with a compact remote control made from a fingerprint-resistant matte plastic that is pleasant to the touch. Its rubber buttons have a soft and quiet, articulate click. The round navigation button has as its rim the producer’s signature red ring. Buttons are few, but they cover all essential functionality. The remote control communicates with the STB via a built-in Bluetooth 4.1 module, which enabled Infomir to put a mic inside it to add support for Google’s voice assistant. The remote does not support Airmouse functionality and Android TV doesn’t need it anyway — its interface is therefore optimized completely for remote and voice control.
MAG425A REMOTE CONTROL
Interestingly, there is a TV Guide button on the remote to launch the Live Channels app for cable TV. The voice assistant is activated with its own dedicated button that also turns on the remote’s sensitive mic. Overall, the remote control is easy to use, its buttons are distinct enough and conveniently spaced. The button layout is so easy to get used to that you’ll find yourself using it without even looking in no time — and it’s a total delight to use, in contrast to, say, Beelink GT-King’s G10 remote, on which the buttons are all flat and clumped together.
MAG425A Set-Top Box Remote Control
The remote is powered by two AAA batteries included in the package. It’s the first time in our experience that a manufacturer cared to include batteries for the remote. It’s great when such little things are not overlooked.
MAG425A Set-Top Box AC Adapter
As shown on the label on its body, the STB’s 12 V, 1000 mA AC adapter is made in China specifically for Infomir products.
MAG425A Set-Top Box AC Adapter
Featuring a fairly robust build, it caused us no trouble during the test drive. It also comes with a 150-cm (4.9-ft) cable attached — a rare convenience for set-top boxes, the usual cable length being limited to about 80 cm (2.6 ft).
MAG425A Set-Top Box HDMI Cable
The HDMI cable is unusually long, too, at 150 cm (4.9 ft) and has fairly good quality. We didn’t have any trouble with it either.
MAG425A Set-Top Box User Manual
The Quick Start Guide includes a warranty leaflet and a brief description of the STB connection procedure and remote control’s functionality.

MAG425A Set-Top Box Review
On the last page of the Manual, you will find a sticker with the STB’s Model Number, Serial Number, MAC address, and production date. There is a similar identification sticker on the bottom of the device.
Appearance
The set-top box has a rectangular body made from fingerprint-resistant matte plastic. On the top cover, you will see Infomir’s signature red ring and a power button. Although convenient, proper power buttons have become rare in devices of this kind, and it was great to see one here.
Near the power button, in the right corner, a set-top box status LED is located. Its LED glows white when the device is on and red when it is in standby mode. The brightness of the white glow can be adjusted in the Settings menu, and the red one can be turned off.
On the left side of the device, two USB ports are located (one of which is USB 3.0), and a hole that hides the factory reset button. There are only two USB ports, but the remote control communicates with the device via Bluetooth, so there aren’t any receivers that need to occupy a USB port.
On the rear of the body, there is a Micro SD card reader slot, which can be used to expand internal storage, an HDMI port, a LAN port, and a 12 V AC adapter connector.
On the bottom of the set-top box, there is an identification label that contains the STB’s Serial Number, MAC address, and production date, as well as a holographic warranty seal. Ventilation openings are also located there to ensure discharge of warm air, as well as two rubber supports to provide the necessary clearance and stability.
Launch. Home screen
During the initial boot, the system configuration wizard is shown, which starts by pairing the remote control to the set-top. For this, you need to press and hold the OK and Home buttons until the remote control’s LED starts flashing red; then, you need to press and hold the On/Off button on the STB’s top panel to initiate pairing. The LED on the remote control will light up and then go out to indicate successful pairing.
Then, the picture size needs to be adjusted to match your screen.
The next step is to choose your language — English is available, as well as Russian and Ukrainian.
Wired/wireless internet connection setup then follows.
Once that is completed, you will be asked to log into your Google account. A smartphone or PC can make the process much easier — you will be provided with a PIN code to input there.
Then you will be asked to accept Google’s Terms & Conditions and Privacy Policy.
The next thing you will do is name your STB, e.g. Living Room TV.
After that, you will be offered a variety of apps to install, including Facebook, MX Player, IPTV, AirScreen, and MX Player PRO. Tick the boxes on the ones you want and select Next.
Finally, you need to read and accept the producer’s User Agreement and Privacy Policy.
After a brief Android TV overview, you will be taken to the Home screen.
Google Home Launcher’s tiled interface comprises several configurable rows. In the upper right corner the system clock, Settings icon, and System Notification hub are located. On the left, the Voice Search icon and a search bar are shown. Voice search can be activated at any moment by pressing the Voice Search button on the remote control.
The first row is your Favorites. You can add here the apps you use the most and sort them as you like. To move an app or add/remove it from Favorites, press and hold the OK button on the remote control once you have selected the app. To see the entire list of installed apps, press the Apps button on the remote control or select the Apps icon and press OK.
Below, recommended content channels are shown. All rows can be scrolled horizontally. Should the need arise, channel rows can be reordered, removed, or added anew.
To reorder channels or remove one, press Left on the remote control and move them wherever you want.
To add channels to the Home screen or remove them, choose Customize channels in the bottom part of the screen. The lowermost one is the Promotional channel, which can be disabled in the settings. The menu is well-suited for navigation with the included remote control and voice commands.
Google Assistant greatly helps with information search, media playback, controlling apps, etc. It is available in many languages, too.
To activate Google Assistant, press the Google Assistant button on the remote control or select the Voice Search icon on the Home screen. To stop voice recognition after you finish speaking, press OK on the remote control.
Voice Search can look up information in all apps that support it.
If Voice Search is started from an app, search results will show hits only from that app.
System and settings
The first time we booted the MAG425A, a notification popped up about the firmware update 1.7.3 being available. The producer maintaining its products’ firmware is always good news. Make sure to install the update — the STB will then reboot.
The Settings menu has enough options to configure, which testifies to the serious amount of customization that went into the device’s firmware. Some menu items are yet to be translated in Russian, but it takes no extra effort to understand what is there.
Network settings are the first in line. The Android set-top box supports dual-band Wi-Fi and wired connection through the built-in LAN port. Then we have audio settings, where system sounds can be turned off and HDMI sound output configured. For the latter, two modes are available: LPCM, where decoding is handled by the set-top box and the sound is sent to the TV decoded, and RAW, where the sound is decoded on the TV or receiver side. In Auto mode, LPCM and RAW are switched as needed.
In the Display menu, font size can be adjusted, interface scaling for 720p and 1080p chosen, Auto frame-rate activated (automatic frame-rate and resolution adjustment depending on the video’s resolution), and picture resolution set. The set-top box supports system-level auto frame-rate in its native player. The custom picture formats available range from 480p all the way up to 4K, 2K 60 Hz.
Also, this is where picture parameters can be adjusted, for example, the brightness, hue, contrast, and saturation. And these settings do work here, unlike in most Chinese set-top boxes. Also, this is where viewport size can be adjusted to suit your TV screen.
In the Video Output menu, aspect ratio can be set and forced 3D frame packing turned on — the device also boasts native 3D support. Two aspect ratios are available — 16:9 and 4:3 — which may come in handy for older TVs. In the Preserve Aspect Ratio section, video extension can be configured, including the addition of black bars on the sides.
The Storage & Reset menu has information about the storage available as well as general data about the device. Only 4 GB of internal storage is available, the other 4 GB being occupied by the OS. The space is limited, but it can be expanded with a Micro SD memory card or a USB flash drive. The default storage device can be configured in the Settings menu — a great choice, given the limited internal storage. Factory Reset is here, too. Also, there is another way to reset the device — a dedicated button hidden in a hole on the MAG425A’s body. During the set-top box boot-up, press and hold the On/Off button on its top cover before the white LED starts blinking — the system will be reset to factory defaults and rebooted. Firmware updates — both OTA and manual — are applied in the About menu.
In Standby menu, the set-top box’s suspend mode can be set to Smart Suspend or Deep Suspend. In HDMI Control Mode menu, the following modes are available: HPD (Hot Plug Detection) — the STB automatically turns on/off when you power the TV on/off; CEC — the STB is controlled with the remote; and None.
In the Advanced Options menu, HDR settings can be changed (the device supports HDR10), and HDCP (a content copy production protocol) can be activated. Also in this menu are the brightness settings for the white LED and the switch for the red standby indicator.
Preinstalled Applications
The device comes with a handful of preinstalled apps out of the box. In the Apps menu, only the Android TV-compatible apps are shown.
To see all the apps, the Sideload Launcher needs to be used.
The device comes with a signature Infomir app suite. It includes Ministra Player (a Ministra TV platform client), the MAGic Files file manager, the MAGic Player video player, and the MAGic Audio audio player. The apps are optimized for remote control and have a great look and feel.
Additional Android TV-compatible apps can be installed from the Google Play Store. There are a great many of them, although the selection is not as abundant as that for regular Android. Alternative app stores can be installed, too, e.g., Aptoide or Yalp Store, from which you will have access to all the apps available on Android.
The built-in YouTube app works great and has no problem handling videos with resolution up to 2160p 4K.
With Chromecast built-in, you can cast media content from your phone, computer or tablet straight to your TV. To start casting to MAG425A, make sure your device and the set-top box are connected to the same Wi-Fi network. Then, open a Chromecast-enabled app on your smartphone and tap on the Chromecast built-in casting button. Then just select MAG425A from the list of devices and the content will be streamed to the big screen.
With the Miracast app, you can even mirror the screen of your smartphone to the TV.
For this, launch Miracast on your smartphone, select MAG425A in the list of available devices, and you will see on the TV whatever there is on your smartphone’s screen. Works fast and reliably.
MAG425A also can be navigated from a smartphone or a tablet with Android TV Remote Control. All you need to do is install the app from Google Play Store or Apple App Store onto your mobile device. Then connect it and MAG425A to the same Wi-Fi network. Launch Android TV Remote Control on your mobile device and select MAG425A from the list of available Android TV devices.
After that, your TV will show a PIN code you need to input into the app and tap Connect. With Android TV Remote Control, you can control the player, navigate the menus, and even use Voice Search. It feels smooth and responsive, and we observed no lags.
System testing
HiSilicon Hi3798M V200
At the heart of the MAG425A is a 64-bit HiSilicon Hi3798M V200 CPU with 4 ARM Cortex-A53 cores running at up to 1,200 MHz. According to AIDA64 though, the clock speed can range from 400–1600 MHz. The GPU is ARM Mali-450.
Hisilicon Hi3798M V200’s key features:
HiVXE 2.0 VPU capable of decoding 4Kp60 10-bit H.265 and VP9, 4Kp30 H.264, MPEG-2, MPEG-4, VC1, VP6/VP8, Real Media 8/9/10
Encoder — H.264/H.265 @ 1080p30 or dual 720p30
Imprex 2.0 processing engine supporting HDR10 & HLG, BT709/BT.2020, etc.
The device’s direct competitor is the HiMedia Q30, based on the same HiSilicon Hi3798M V200 and having the same 2 GB RAM and 8 GB of internal storage.
MAG425A is running Android TV 8.0, but Infomir guarantees that the Android TV 9.0 update is just around the corner. Firmware version — 1.7.3
The set-top box offers no root access.
As concerns the DRM certificates required by paid apps (Disney, Amazon Video, BBC, HBO, Facebook, Hulu, Spotify, etc.), Google Widevine DRM Level 1 and Microsoft PlayReady SL2000 are supported.
RAM and internal storage showed good performance:
● RAM transfer rate: 1,670.50 MB/s
● Internal storage: read: 56.06 MB/s; write: 17.74 MB/s
● USB transfer rate: read: 674.93 MB/s; write: 3.24 MB/s
Network Connectivity
We had no problems connecting the set-top box to the web via Ethernet and Wi-Fi. Its Wi-Fi module ensures stable and fast connection, even faster than the Ethernet. The set-top box has a dual-band 2.4/5 GHz Wi-Fi capability and a 10/100 MBit/s Ethernet port. During the test, our entry-level Tenda AC10 gigabit router (a great model, BTW) was placed in a room adjacent to that where the STB was — 5 m away with a brick partition between them.
MAG425A is equipped with a highly integrated dual-band RTL8822BU Wi-Fi module with MIMO and Bluetooth capabilities. During the test, SpeedTest showed connection speeds equal to the maximum declared by the provider — 100 Mbit/s upload and 100 Mbit/s download — for 2.4/5 GHz Wi-Fi as well as a cable connection. This means that you will be able to enjoy 4K video no matter how you decide to hook the STB up to the internet. Throughout our test-drive, the Wi-Fi connection was stable and reliable. We experienced no disruptions forcing us to reconnect.
Heating
MAG425A is running Google-certified Android TV OS, which provides no access to CPU temperature sensors in view of licensing constraints. However, the very fact that the device managed to pass certification testifies to its reliable and overheat-free operation. Therefore, you won’t be needing to check the CPU temperature.
Video Playback
High-quality IPTV and VoD content is notoriously demanding to hardware — most of the CPUs widely used in STBs are barely capable of processing high-quality videos, which results in artifacts and frame skipping that are especially noticeable in fast-paced action scenes.
In our IPTV test, we used the OTT Navigator app and the Fox-TV IPTV service, which offers over 430 channels, of which 190 are broadcast in HD quality and 8 — in 4K.
The set-top box performed on all channels as advertised. The HiSilicon Hi3798M V200 CPU has no problems handling high-bitrate video streams, ensuring almost ideal picture quality.
The VoD performance was assessed with MEGOGO, a popular online service.
No problems were encountered while using the app, all videos were streamed at maximum quality.
We also used videos with different encoder settings and bitrate to test the STB’s capabilities:
● Sony 4K — Camp HDR MP4/HEVC 10bit — 75.8 Mbps
● Jellyfish 4k uhd HEVC 10bit — 140 Mbps
● Jellyfish 4k uhd HEVC 10bit — 200/250/300/400 Mbps
● LG Demo — Istanbul 3840×2160 MP4/H264 8bit — 116 Mbps
● Demo Samsung 2014 — USA Road Trip TS/HEVC 10bit — 51.4 Mbps
● Demo Samsung 2014 TS/HEVC 10bit — 51.4 Mbps
● Ducks.Take.Off.2160p.QHD.CRF25.x264-CtrlHD.mkv — MPEG4 Video (H264) 3840×2160 29.97 fps
● Philips Surf 4K Demo.mp4 — HVC1 3840×2160 24 fps 38013 kbps
● LG Cymatic Jazz 4K Demo.ts — Video: HEVC 3840×2160 59.94 fps
These all played without picture or sound distortions. The device easily plays 480p, 720p, and 1080p video (24 fps, 30 fps, 60 fps), as well as 4K 60 fps one, and supports a wide variety of codecs, like H.264 , H.265 , MPEG2, and MPEG4.
Gaming Capabilities
With Bluetooth, you can connect a gamepad to the STB and have a great time playing most undemanding 3D games, e.g. Subdivision Infinity, Real Racing 3, Beach Buggy Racing, etc. Keep in mind though, that gaming is the last thing this STB was built for.
CONCLUSION
Infomir MAG425A is a flagship model in the longtime manufacturer’s product line. It passed official certification by Google, meaning that it is a high-quality and reliable device. The device showed great performance in all tests, its interface is snappy and responsive. No lags or freezes were encountered. The STB is capable of playing whatever video content you throw at it, including 4K HDR10 @ 60fps. The MAG425A enables viewers to connect to their IPTV/OTT provider, watch streaming content, and play files from a local storage. Overall, it has a host of upsides, so if you are looking for a reliable and easy to use set-top box of great quality for home entertainment that supports Voice Search and comes with robust manufacturer warranty and support, with MAG425A you will get maximum bang for your buck.
MAG425A is officially available for sale in Ukraine and worldwide.
