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 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. However, while normally I’d use my own HDMI cable, I had to use the provided cable since the device features a mini HDMI port.
Once you connect the power the power button LED on the unit turns red, and you need to press the button to boot it up, with the LED switching to blue color. A typical boot takes about 30 seconds. If you don’t use the camera, you can fold it down when you don’t use it if you have privacy concerns.
The launcher is optimized for TV use, and the user interface has a 1920×1080 resolution. It includes shortcuts to other “folders” like Online Video, My recommend, My Apps, Music, or Local, and a shortcut to Settings. It also features a customatizable row of shortcut right under the main buttons. The status bar is there. but can also be hidden. I went to the settings to check video output was set to 4K 60Hz, and it was the case.
But let’s get to the main selling point of the TV box: its camera. I’ll start with the camera app.
The quality is what you’d expect from a 2MP camera, and it will save 1600×1200 JPEG photos, and record 1280×720 MP4 videos.
Most people who probably such TV box for video conference purpose, so I’ve tried what I consider the most popular video conference apps in Android: Skype, Google Hangouts, and the latest Duo by Google. I’ll describe my experience first, but you can also jump directly to the video demo further below if you want.
Skype is pre-installed, but I still tried to install the latest version with Google Play, and for some unknown reason type “skype” would make Google Play crash just went I typed the letter “e” with the air mouse. When I tried the pre-installed Skype, I could register an account and login, but calls would not work. So I searched in Google Play again using the USB keyboard, and it let me update the app.
I could use the Echo services to test audio calls successfully, and I also successfully called another laptop for a video call.
I had no problem install the app from Google Play, and the first time I tried I got both the caller and callee videos on the screen, but subsequently I lost video on the Android TV box, but both video feeds would still show on the laptop, and audio was still working. So there may have been a network issue in one direction…
Duo is the latest one to one video calling app by Google, which is supposed to be very easy to use compared to something like Hangouts. SO I was eager to test it, but it’s incompatible with the TV box. [Update: I’ve just tried Duo on my phone ,and it requires a phone number, so that’s probably why it won’t work on any TV boxes]
You can watch the device in action with the Camera app, Skype and Google Hangouts in the short video below.
I think my latest RK3368 TV box review was with Zidoo X6 Pro in October 2015, so it’s probably a good idea to check if any have changed since then by running CPU-Z and Antutu 6.x.
While all other devices with Rockchip RK3368 showed it clocked at up to 1.2 GHz, but RK3368 inside Coowell is instead clocked at up to 1.51 GHz, not that we should not always blindly trust CPU frequencies returned by the kernel. Other info shows 2GB RAM, 12.42 GB internal storage, 1920×1080 screen resolution, and Android 5.1.1 running on top of Linux 3.10.0.
So with that faster CPU clock, we should expect a higher Antutu score, right?
Nope. The score was just 23,445 points, while this type of device should have a score in the 3x,xxx. I repeated the test again in case something went wrong, but the device only achieved 22,870 points in my second try. I also noticed audio noise instead of music, during 3D graphics benchmarks for both tests.
