Hello, i just bought an economic Android tv for my mother, an Hitachi model HAK6157. I notice that the tv is always connected to internet, even when is powered off. Is it possible to let that not happen? Also, i noticed on my Cast devices on Youtube app that a deviced appeared, and it’s named hbbt_remote_launch. I already stopped the the Chromecast built in app, but it’s not resolutive. Thank you in advance!
