Review of CX-S806 TV Box Powered by Amlogic S812 Processor

I’ve already reviewed one Android media player based on Amlogic S812 processor with MINIX NEO X8-H Plus. Today, I’m going to have a look at another S812 TV box, namely CX-S806, with lower specs, and less support, but that sells for half price compared to the MINIX device. I’ve already published pictures of CX-S806 media player and board, so today I’ll focus on testing the performance and features of the device. First Boot, Settings and First Impressions The package include a simple IR remote control, so I inserted two AAA batteries to give it a try, and it seemed to work OK, but as usual I switched to use Mele F10 Deluxe air mouse for the rest of the review. Since I’ve connected Ethernet and HDMI cables, a USB hard drive, a USB webcam, and a USB hub with two RF dongles for the air mouse and wireless gamepad, and […]
