Booting Android to the “home screen” takes about 00:41.6 seconds (well enough). “Home screenlauncher K1 Plus looks very, very simple and easy to useThe same launcher before we could see in ZIDOO X1. Perhaps Videostrong works with ZIDOOIn addition to the remote control I used the standard keyboard, mouse and PROBOX2 Remote+. Unfortunately I could not use Xiaomi gamepad because tested model K1 Plus does not have Bluetooth.

The device worked in the resolution of FHD 1920×1080 (1080p 60Hz) but you can also adjust the preferred resolution (also 4K) or set the auto mode On the launcher we have access to the most important features: settings, apps, browser, file manager, kodi. K1 Plus comes with pre-installed applications such as IPFox and Private Live TV with IPTV channels. K1 Plus has also DLNA, Miracast and Airplay. I had no problem with Ethernet and WiFi connection to my router. The remote control works without a problem also with PROBOX2 Remote+ there were no problems, everything worked quickly without delays. Below a few screenshots.

K1 Plus is another TV Box which has KODI Isengard with additions (more precisely KODI 15.2 Isengard). Below screenshot from Kodi.

On K1 Plus TV Box you can play without a problem. Beach Buggy Racing and Jetpack Joyride runs reliably and without problem, also I was able to run Asphalt 8: Airborne which also worked without problems.

asphalt8Operating system and components

The K1 Plus TV Box runs on the Android 5.1 Lollipop, namely version 5.1.1 and the Linux Kernel version 3.14.29. The firmware installed on the device received for revie had a problem with compatibility with Google Play (you can not install applications from Google Play).

firmwareTherefore, to complete the tests it was made a firmware update (2015-11-23). What solved the problems.

firmwareTV Box is equipped with a SoC Amlogic S905 Quad core 64-bit  Cortex A53 Up to 2.0GHz processor and GPU Mali-450, CPU speed between 100 MHz and 2.02 GHz. On the following screens you can see exactly the components used and their specification (Information taken from the application AnTuTu Benchmark v5.7.1, CPU-Z and AIDA64). Unfortunately, Amlogic S905 is not yet recognized in the applications only detected ARM CortexA53. Also, the model device is detected as K1 Plus (p20x) and board p20x.

Performance tests and benchmarks

For testing I use the app AnTuTu Video Tester 3.0 and AnTuTu Benchmark 5.7.1. The following screenshots from the video test. The result 886.  A better result was achieved PROBOX2 EX + with Amlogic S812 – 1024!. ZIDOO X6 Pro with RK3368 – 530. As you can see, Amlogic processors better falling out in the tests. Interestingly the TV Box with a newer processor Amlogic S905 came out worse than the S812. Perhaps the machine needs more optimizing or overclocking.

Video playback by Kodi Isengard (15.2) and MX Player runs smoothly and stable. K1 Plus TV Box without problem seems plays movies with the resolution of 480p,720p and 1080p (24fps, 30fps, 60fps) and also 4K (small problems with 60fps) with various codecs video such as H.264, H.265, MPEG2, MPEG4, RMVB and audio – DTS and AC3. Also I tested several video formats – AVI, MKV, MP4 (typical formats in which it holds the majority of films) and also videos was played without any problems. The K1 Plus tested 4K video play without any major problems. The following table compares Kodi and MX Player for some video samples.

Most of the samples was played without problems, sometimes jumping or minimal blur. Failed to play VP9 (H.264 @ 60fps). By contrast, which was quite strange that most of the samples after the start began with a black screen.Only after the re-start from the beginning, the video was played correctly. 4K video is playing very well.
