Coowell V4 Android TV box is based on Rockchip RK3368 octa-core processor with 2GB RAM, and 16GB flash, and also includes a camera. In part 1 of Coowell V4 review, I have already taken photos of the device, and torn down the device to have a closer look at the board, and the camera which is based on a GC2145 2MP image sensor. Today, I’ll mostly test the camera and microphone, including firmware compatibility with Skype, Google Hangouts, and the latest Duo by Google app. Finally, it’s been a while since I’ve tested a RK3368 TV box, so I’ll run CPU-Z and Antutu again. Coowell V4 Hardware Setup and Launcher Coowell V4 hardware setup is pretty usual, and I connect an Ethernet port, and the USB RF dongle for MINIX NEO A2 Lite air mouse, as well as a USB keyboard to take screenshots.

Allo Sparky Audio Kit Combines an ARM Linux Board with Amplifier, Audio DAC, Reclocker and Capacitance Multiplier Boards
Last year I wrote about Allo Sparky SBC Linux and Android development powered by Actions Semi S500 quad core Cortex A9 processor, which mostly differentiates itself from the competition by the many add-on boards for audio, VoIP, and IoT (WiFi+Bluetooth+Zigbee ). While most of development boards are manufactured in China, Allo company is based in India, and all boards are manufactured there, which could be a benefit to Indian readers who want to avoid potential custom issues with other boards. The company has shipped me their complete audio development kit, and I’ll first check out the hardware, before taking time to experiment with the kit in a few weeks or months… I could find 6 different boards in the kit, which I detailed below, as well as a 5V/3A power supply with AU and EU adapter, a micro USB adapter, a micro SD card apparently pre-loaded with Ubuntu 12.04, a […]

VR SKY CX-V3 Allwinner H8vr All-in-one Android Virtual Reality Headset Review – Part 1: Specs and Unboxing
I’ve heard about standalone Android virtual reality headset for a while, but so far I had never tried one, except using my phone with a cardboard kit, which was not such a good experience. So when GearBest asked me whether I want to try one of the Allwinner H8vr virtual reality kits, I thought it was a good idea, and today, I received VR SKY CX-V3 model. Today, I’ll just list the specs, check out the device and accessories, and report my first impressions, before posting a review about my experience in a few weeks.

Vernee Apollo Lite is the little brother of Vernee Apollo, both based on Mediatek Helio X20 deca-core Cortex A72/A53 SoC, but with the Lite version having lower hardware specs otherwise, and being one of the few ARM Cortex A72 smartphones selling for less than $200 (at least in China). Tomtop, a Chinese online store, sent me a sample for review, and today, I’ll start by going through the tech specs, then check out the phone design and its accessories, and finally run a few benchmark, before posting a more detailed review in one or two weeks, where I’ll have more experience and feel about the phone. Vernee Apollo Lite Specifications I had posted some specs about the phone when it was first released, but they were incomplete at the time, and Vernee now released the full specs for their Apollo Lite: SoC – Meaitek Helio X20 (MT6797) deca-core processor with […]

Tanix TX5 Pro TV Box Review – Part 2: Modding and Testing
Karl here with part 2 of Tanix TX5 Pro TV box. In the first part we peaked inside took a look at the specs and quick look at the UI. In part 2, we will get into the nitty gritty. When I first received the box there were several issues: Play Store incompatibility, issue with language reverting to Chinese, and green screen on YouTube. Tanix quickly followed up with an update and resolved these issues. Stuck in my ways So I have to admit that I am pretty stuck in my ways when it comes to the way I use Android. It started long ago with my first stick the MK808 with Rockchip Rk3066. It was basically the phone version of Android on the TV and I really liked it. We have come a long way since then and some changes have occurred in the box market UI, like the […]
Amlogic S905, S905X, and S912 Processors Appear to be Limited to 1.5 GHz, not 2 GHz as Advertised
When I compared the performance Amlogic S905 and Rockchip RK3368 processors last year, I noticed Amlogic S905 single thread performance not being much faster than the one of Rockchip RK3368, despite the former allegedly clocked at 2.0 GHz against the latter 1.2 GHz. But early this month one member (koschi) on ODROID forums started a thread entitled “No performance difference between 1.5, 1.75 & 2GHz” about ODROID-C2 board. The first post link to Ant-computing website about choosing a processor for a build farm, and one of the tables comparing various ARM and x86 processors with the claim that Amlogic S905 was listed to 1.536 GHz, because “the device claims to run at 2.016 GHz but the kernel silently ignores frequencies above 1.536 GHz!” So koschi did his own tests with 7z and sysbench, using cpufreq-set -u $FREQ to set a fixed frequency between test, and could confirm the issue:
