YOKA KB2 runs on Android 6.0. The front panel (in a small window) has IR receiver with power LED, and Power button. On one side there are two USB 2.0 ports (one USB 2.0 OTG) and micro SD card slot. On the rear panelare: RJ45 Gigabit Ethernet port, Optical S / PDIF port, AV port, a small hole forrecovery firmware, HDMI 2.0a, 5V DC jack.
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.
