I got this TV box new in an eBay auction for only USD25, and although I had read about its limitations to install apps outside Play Store I bought it. Unfortunately those limitations are real, limiting greatly the potential this box has (16GB internal, USB full size port, Ethernet port, S905X2 processor). Is there possibly a way to activate unknown sources installations via ADB? The box does not even have a usb debugging switch in the developer options, and I have not been able to detect it either via wifi or via USB attached to a computer. The other glaring issue is the lack of Netflix-Widevine certification, so it can run pretty much anything, but the big N can't be downloaded from the play store. Should I just wait until a software update changes these limitations or I should just sell it?
The KA2 is mainly a video calling device, not for streaming per se
