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.

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 […]

How Fix Apps Crashing at Launch in Android 6.0 (in Mediatek Phones) ?

I’ve recently received a new Android 6.0 Marshmallow smartphone powered by Mediatek Helio X20 processor, namely Vernee Apollo Lite, and one of the issues I encountered is that some applications such as Firefox and MAPS.ME would crash when I tried to launch them. The problem was reproducible 100% of the time, and occurred from the very first time I tried to start the app. I’d get a message like “Unfortunately MAPS.ME has stopped” with two buttons: REPORT or OK. So I asked on Vernee forums to report the issue, and see if other people had the same problem. One replied had the same problem, but a simple reboot would fix the issue, while the other proposed to clear the cache. I had not considered that option since the crash occurred from the very first time, but I tried anyway. Go to the App list, drag and drop the problematic app […]
