Connection and desktops

After connect the QINTEX R33 to the power source and this boots directly, we have a launcher based on squares where we have access to Google Play, Kodi, browser, settings and different subcategories. In the lower part we have a row where we can add optional shortcuts with our apps. We can change the default launcher by installing another. The resolution of the system is 700p and it is something that can be seen in the image quality of the Android environment and streaming apps.

  • Boot time: 22 seconds

User Experience

The Qintex R33 TV-Stick runs fine in Android thanks to the Rockchip RK3328 Quad core processor moves without problems the demanding apps and the Android environment with native 720p resolution. In this model we have 2 GB of RAM a correct number to move the most common apps, from the shortcut bar we have the multitasking function that allows us to easily change between running apps.

Android Settings

Installed in the QINTEX R33 we have the classic lateral settings of Android 7.1 where we have specific options for the TV-Box such as screen resolution and audio settings.

Qintex r33 review f006 min

If we click on the Settings app we get to the Classic Settings of Android we have some options more than in the previous settings but they are quite limited and it seems that some menus have been cut that would have allowed us to fine-tune the system.

Android System

In the Qintex R33 we have Android 7.1.2 installed, a system still quite current. The kernel as we see is specifically version 3.10.104 and the compilation has a date of 2018-05-23. With this version we have made the review that you can read in the following pages.

Brand Support

The web of the Himedia brand has a download section where we can download the updates of the system, although we lack the IMG files to recover the TV-Stick from a PC in case of problem.

Storage and RAM

The TV-Stick QINTEX R33 includes 16 GB of eMMc storage memory, from this storage memory we have actually available about 10 GB, a figure enough to install a good number of apps. As a device with Rockchip SoC this has a single partition in the storage memory which facilitates the management of our files.

Himedia A5 review f023 min

In the memory aspect we have 2 GB of DDR3 RAM that behave normally, of this amount we are still available about 1.1 GB at boot, we can load several apps without noticing slowdowns in the system.

Consumption and temperatures

In the terms of power consumption the QINTEX R33 with the RK3328 SoC shows results within the range of other devices, even putting the SoC to the brim with games with 3D graphics only 5.5 W peak is reached.

We pass a performance test where we can see how we have a loss of only 10%, the low consumption of the SoC RK3328 of this TV-Stick does not generate much heat.

Qintex r33 review f027 min

The temperature in the certer are quite high but we have not noticed any loss of performance running intensive applications, normally the CPU works at maximum of 1.51 GHz.

Google Play and Amazon App Store

We enter the Google Play store where we have no problems installing the most common apps and download them automatically into the internal memory, we can use Amazon appstore as a alternative.

We checked that the QINTEX R33 system checked that we have root, something that allows us certain options and do not affect the services such as Netflix or Amazon Prime Video as we will see in our review in the corresponding section.

Power Off / Standby / Power On

When pressing the power off icon in the QINTEX R33 the system gives us the option to turn it off completely, but we must bear in mind that we will have to reconnect to the current to turn it on.

Video and audio connections.

Integrated into the QINTEX R33, we have the Rockchip RK3328 SoC, a product that supports HDMI 2.0a video output, which allows maximum resolution up to 4K@60fps and also supports 10bit color and HDR content. We can change the size of the mouse pointer and the captions of several streaming services following our turorial.

Qintex r33 review f015 min

In this system, there is no automatic refresh rate option, which would be interesting since it avoids reproducing content with the annoying Judder effect. Within the classic screen settings we find control of brightness, contrast and sharpness, if we notice the dark scenes in our TV models we can fix it with this tutorial.

DLNA and Miracast

Installed in the QINTEX R33 system we have the apps Miracast and Happycast that allow us to play content with a LG G6 Smartphone, an app that gives us correct results but can be variable depending on the device.

Qintex r33 review f017 min

We can use the DLNA service to access the multimedia content that we have in our device easily using an app like BubbleUPnP from an Android mobile or from a PC with Windows file explorer.

We test the TV-Stick for videoconferencing with the QINTEX R33 we use the simple webcam Logitech C170, in this case, the app does not seem to work due to a firmware problem.


Wi-Fi and Ethernet

Installed in the QINTEX R33 we have a ac Wireless Wi-Fi Adapter and Gigabit Ethernet chip, with which we have connected with an ASUS RT-AC1200G+ Router, a mid range device. We test the network using streaming using the iPerf measurement tool with which we have the maximum connection speed in each adapter. Connected by Wifi 2.4Ghz we have achieved a speed of about 17 Mbps, through the 5GHz Wifi network we reach up to 191 Mbps. As we see the 2.4GHz network has given us performance problems and to connect the 5GHz network we need to connect by entering the name of the network manually, a bit peculiar in this regard.

During the Wi-Fi coverage tests with the device located at a distance of about 16 ft as always and with a wall in between we verified that we have connection without cuts, the signal reaches a level of about 44 dBm a low result, a correct result for an external antenna and that stays fairly stable.

Remote control app

By default in the QINTEX R33 we can use the alternative CetusPlay to control it from our mobile or tablet, we only need to install the server in our TV-Stick and the client app in or desired device.

Gamepad and games

You can play games on the QINTEX R33 connecting a Gamepad with cable or bluetooth that work without problems, we can use this control in the games with this type of support, in general we will not have problems with conventional PC control. We can use them in games with this type of support, in general we will not have problems with conventional PC controls. With the Mali-450MP2 GPU that incorporates this SoC we have basic performance we can’t play titles like PUBG Mobile.

game review 02



Within the Qintex R33 we have as core the Rockchip RK3328 SoC that includes four processors ARM Cortex-A53 of 64bits and a GPU Mali-450MP2. A correct SoC for a basic use, this processor works between 408 Mhz and 1.51 GHz depending on the performance needs of the system. In the performance tests as we can see we have figures that indicate the basic character of this SOC. In general we can use it to run any simple app or play multimedia without problems.

Video format test

In video playback tests the Qintex R33 with the Rockchip RK3328 SoC in this model has out-of-the-ordinary results compared to other devices with the same SoC. It is possible to reproduce the most common files without major problems at native resolution in a fluid way with 8-bit color files with 4K@60fps resolution encoded compressed with the h.265 or VP9 codec, but we have compatibility problems with HDR modes and files 10 bit color. It seems to be a problem of firmware since we have the same results in KODI or MX Player. This firmware comes standard with the one version of KODI called RKMC that does not go very well, we recommend installing the Google Play version. Although the Android environment is rendered at 720p video files if reproduced at its native resolution up to 4K.

  • This model is compatible with LibreELEC as we have checked using our LibreELEC a quick installation guide.
    All network adapters work perfectly and even the remote command is perfectly mapped.

Audio format test

In the QINTEX R33 we have the Rockchip RK3328 SoC Quad Core that as we know it is NOT licensed for the use of audio pass through for DD and DTS. For the sound tests we use our Yamaha RXV-577 AV receiver and we naturally check that in the device we have audio pass through for DTS  and DD5.1 although in some  7.1 formats we have noticed audio errors, although it is much better in this respect than other RK3328 that we had tested.

At the level of DRM certificates needed for some payment Streaming apps we have Google Widevine L1 installed by default, something that allows us to see Google Play Movies without problems but that we can’t use to see Netflix HD because the firmware is not ready. It seems that Himedia is getting the Netflix certificate and soon we will have news about a version using Android TV on this type of hardware.

Streaming services with subscription

We do our battery test as usual on the most popular streaming services to verified if can work correctly, the power of this device is more than enough to see any type of content on this services, although as we know we are limited on the streaming quality for the restrictions of each company. In this model we have a basic support for streaming apps without certificates.

  • NOTE: We remind that these TV-Stick do not have official support for these streaming apps, the compatibility with these services can vary depends of any new limitations imposed for this companies. The tests are perform with the indicated firmware and the version of the streaming app at the date of the review.

After testing the Qintex R33 we can say that we are facing the classic TV-Stick, we have decent specifications but as always in this format we have connection limitations. It should be noted its small size, general stability, the inclusion of 2GB of RAM, Wifi ac and Android 7 system that leaves it in good place for a general use in a basic use if we need a team of small dimensions.

On the other hand, the Qintex R33 is a device that has certain performance deficiencies in the 2.4Ghz Wi-Fi band and 10bit color video playback, maybe they are solvable aspects with a firmware update but for now, as we have seen, they are weak points, if they are important points for us, there are other better options. In short a device of very small size but with things to improve.


  • The QINTEX R33 can be purchaed in only for $74 (65€) plus shipping cost included.
