At the bottom of the device there are holes for the discharge of hot air, and MAC address. Below also remote control. Remote control is quite large, but very well fits the hand, and has a key function to which you can assign your preferred applications function known from the ZIDOO TV Boxes.

Below we include the YOKA KB2 4K UHD TV Box photos in combination with a matchbox so it was easier to see the size of KB2 Android TV Box.

Booting Android to the “home screen” takes about 00:33:03 seconds. Yoka KB2 has a very simple and easy to use launcher. The device worked (typcally) in the resolution of FHD 1920×1080 (1080p 60Hz) but you can also adjust the preferred resolution or set the auto switch. Everything worked stable and very quickly without delays, Netflix (Netflix offline) also works without problems. YOKA KB2 TV Box is suited to Netflix offline you know where you can use the 32GB of eMMC storage 🙂 ). KB2 TV Box support also DLNA, Miracast. We had no problem with Ethernet and WiFi connection to router and to Internet. In addition to the remote control I used a standard keyboard and mouse, Gamepad GameSir G3s, and Xiaomi gamepad. Below a some screenshots.


YOKA KB2 TV Box as one of the first to receive pre-installed Kodi v17 “Krypton”.


On KB2 TV Box games from Google Play are working properly.  You can play without a problem just connect gamepad or airmouse and keyboard. We used GameSir G3s and Xiaomi gamepad. The combination of YOKA KB2 with gamepads is great fun. Beach Buggy Racing, Asphalt 8: Airborne works without problem, even with high resolution works trouble free.


Operating system and components

The YOKA KB2 runs on the Android 6.0 Marshmallow, namely version 6.0.1 and the Linux Kernel version 3.14.29. KB2 TV Box comes with firmware build number KB2-userdebug 6.0.1 MHC19J 20160827.135930.V0701 test-keys. It was enough to connect the TV Box to the Internet, and we have access to updates via OTA (Big plus!). There was no need to do anything special, no flash method etc. We updated device via OTA to firmware version build number KB2-userdebug 6.0.1 MHC19J 20161007.155515.V0701 test-keys.

TV Box is equipped in the recently very popular a SoC Amlogic S912 quad core ARM Cortex-A53 @ up to 2GHz processor and GPU ARM Mali-T820MP3, CPU speed between 100 MHz and 2.0 GHz. On the following screens you can see exactly the components used and their specification (Information taken from the CPU-Z app). CPU-Z app does not recognize too well Amlogic S912. The device is detected as KB2 (q20x)and board q20x. Below some screenchots.

After using the DRM info (app) we know that KB2 TV Box supports Google Widevine Moudlar DRM, but unfortunately does not support Microsoft Playready DRM, Marlin DRM and Verimatrix VCAS.

Performance tests and benchmarks

For testing I use the AnTuTu Video Tester 3.0 app and AnTuTu Benchmark 6.1.4. The result 858. Also worthy of note is that KB2 TV Box did not have not supported codecs.



Video playback by Kodi v17 “Krypton” and MX Player runs smoothly and stable The YOKA KB2 without problem seems plays movies with the resolution of 480p,720p and 1080p (24fps30fps, 60fps) and also 4K (60fps) with various codecs video such as H.264,H.265, MPEG2, MPEG4, RMVB and audio – DTS and AC3. Dolby Digital 5.1 passthrough worked fine via HDMI. Also I tested several video formats – AVI, MKV, MP4 (typical formats in which it holds the majority of movies), ISO and also videos was played fine. The tested KB2 TV Box plays video files in 4K (also 60fps) almost without any major problems. The following table of video samples tested for Kodi. TV Box Also copes well with playing the video on YouTube – videos plays in 1080p. Also, we tried to play VP9 4K video and also runs smoothly without any problems.
