Review | Rikomagic MK22 (Amlogic S912) Android TV Box

MK22 from RikoMagic is the company’s latest offering, based on the new S912 chipset by Amlogic. Rikomagic may be less known than the market leaders (Minix, and until recently Tronsmart), but it is constantly pushing ahead and building a name for itself.

We were pioneers of the Android Mini PC concept and were the first Android Mini PC provider. Based in Shenzhen, China, Rikomagic aims to revolutionize the digital media player market. Our Research and Development team has extensive expertise in consumer electronics products and the development of network media players. Our core strength remains focused around Android PCs and Android Mini PCs, where we have a great deal of experience.

I want to thank Rikomagic’s Michelle for the review sample, and look forward to further fruitful collaborations in the future!

What’s in the Box?


As can be seen, the box contains only the necessities: A standard IR Remote control, HDMI 2.0 cable, and a DC power adapter.

Looks & Design


MK22 is a black plastic box that is of a simple yet appealing design. The external antenna is built-in in this model. There is no On/Off button – you can only turn the box on and off from the remote, or by pulling out the power cord (not recommended).

Benchmarks and Testing


Antutu Benchmark


mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,antutuThe Antutu benchmark tests single core performance over multi-core as it is a better indication of the performance of one device over others in most situations. MK22 takes the 9th place in this test, placed between two S905 based boxes. This does not bode well for a S912 box, but as further testing shows, this is not the complete picture.

GPU Mark Benchmark


GPU Mark tests 3d gaming performance and also provides a normalized score according to the used screen resolution (for a more accurate result). The test is quite short and should be taken as a supporting result to that of the more serious 3D Mark benchmark. MK22 took the (quite) respectable position of 5th and 6th in this test ratings. Putting it right along with other (older) octa core boxes based on RK3368 and RK3228. It surpassed S812 boxes, and finally – also S905 based boxes.

A1 SD Benchmark


A1 SD Benchmark tests RAM and flash memory speeds. As can be seen in the provided graphs, RAM is much faster (by a factor of about 40) than flash memory – that is why it’s in smaller amount and is also volatile (does not retain its contents after a reboot). The read/write internal & external performance is a mixed bag with poor results for the external micro-sd read and write tests, but internally, the box was quite fast and was positioned in 5th place after only S905 and S912 boxes. The RAM copy speed, however, is a different story and the MK22 zipped past all other competition to become the new number one contender in the race.

PC Mark Benchmark


mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,pcmarkPC Mark is a benchmark that tests several real-world aspects of android devices. Tests such as web browsing, photo editing, writing (copy, cut, paste) and so on. The all-around results for the MK22 placed it in the mid-position at number 11. This is a shame, since this is a powerful box by all accounts. Hopefully, the MK22 work performance will improve with future firmware updates.mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,pcmark,work 2.0

This addition screenshot is of a new (“Work 2.0”) version of PCmark that came out recently. As I do not have any comparable data to allow for gauging the work 2.0 performance, I just put this test result here for your consideration.

3D Mark Benchmark


mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,3dmark3D Mark benchmark is considered as one of the best ways to test 3d performance on Android (and other platforms). MK22 shows again it’s 3d performance strength and gets placed in the (very) respectable 3rd place – after only two other boxes based on RK3228 and RK3368 chipsets.mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,3dmark,slingshot

MK22 supports the more advanced “Slingshot” 3dmark test, and again, even though I lack sufficient comparison data, I put this result here for your perusal.

Usage and Performance


mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,root,checkMK22 comes pre-rooted, as can be seen in the photo above. However, as in many cases, the root is not done with SuperSu but with Superuser. And I wouldn’t mind that, but the Superuser app itself is hidden and so it’s quite difficult to manage the permissions.

mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,home,screen

The home screen is quite standard with the familiar tile arrangement. I did not try to install other launchers, but I believe there shouldn’t be any issue doing that.

Thankfully, the bottom bar was not cancelled or editted in Rikomagic’s firmware, so using the internal screenshot tool was possible and easy.

MK22 in general is a good performer, with some rough edges that may be sorted out with firmware updates. For Kodi it’s a solid performer, even though the 4k over LAN performance is not as uniform as I would have liked.

Bugs & Issues


  • MK22 experienced several crashes from Kodi to the android home screen, both while scrolling video file list on a locally connected hard drive, and while playing back video. Issue resolved by un-ticking amlogic hardware acceleration option in Kodi
  • Sticky keys in remote – over scrolling without long presses
  • No working OTA (over the air firmware update)
  • Green flashes (common issue with S912 boxes) appear sometimes at the beginning of playback
  • Slow WiFi performance
  • Older pre-installed Kodi (16.1) less optimized for the new S912 chipset

Network performance


Network performance has been tested using Speedtest.net Internet speed measuring app, in WiFi and in Wired mode. My Internet connection is 200 Mbit Synchronous Fibre connection. Speeds measured are Wireless 2.4 GHz, Wired (LAN over Power-lines), and Wireless 5 GHz:mk22,rikomagic,review,amlogic,s912,android,tv box,games,benchmarks,tests,speed,internet,kodi,4k,fullhd,ultrahd,1080p,720p,speedtest,internet,network,connection,wifi,LAN

Video Playback testing


Video playback testing was done with Kodi 16.1 which comes pre-installed on the MK22:

Resolution Video Format Local Playback Network (Wi-Fi/LAN) Playback
720p (1280*720) AVC (High@L4.1)  Playing correctly  Playing correctly
1080P (1920*1080) AVC (High@L4)  Playing correctly  Playing correctly
2160P (3840*2160) HEVC (H.265)  Playing correctly Playing correctly
4K (4096*2304) AVC (High@L5.1)  Playing correctly  Audio Loss, Stutter, some Play fine
4K / HD / FullHD HEVC (H.265) 10Bit  Playing correctly  Buffering

As long as you stick to videos up to 1080p, or use higher resolution files locally (Micro-SD card or a USB hard drive), you should be fine.

MK22 Conclusions


Did I like it? Yes. It surprised me in some aspects, and still has room to grow in others. I did not like that the OTA firmware update is broken (even after a recent manual firmware update), and that the pre-installed Kodi version is 16.1 and has issues with 4k files over LAN (possibly due to lacking WiFi performance). But in general, it is a good all-around box, and if they will follow up with my findings it will even be great.

Would I recommend it? Yes, among the s912 boxes it is definitely one of the best ones I tested so far.

    What do you mean be that? :

      the OTA mechanism is broken. It cannot connect to the update server. Update is possible, but only manually for the time being (using Amlogic’s USB Burning Tool) – from PC.

    Thank you very much, I will write to Rikomagic’s technical support to see that they say to me because it turns out that it puts on the screen of pink color occasionally and is very troublesome.
    Sorry for my bad english.
