Same here, Philip has guided me a lot on IPTV when i just started exploring on this topic. Without his guidance, i dont think i would be able to set-up stbemu on my device. So far so good, i have not been hacked or whatsoever. But of course, i dont keep any personal data on my TV or android box anyway (who does that?!).

On whatsapp communication, i think so that it'll be easier to type and communicate? So far so good for me.
