Hello, I have the Roku Ultra and I don't want to have my kids to install channels without my knowing about it. I have set a PIN for installing any new channels, however, my kids recently discovered by simply saying the channel name into the remotes search feature it will install the channel without prompting for a PIN! For example, if they said "YouTube" it will be installed.
I would like to disable the voice feature since nobody in my household uses it for anything.
Sorry there isn't a way to disable it, except stop using the original remote go with a roku IR remote or an aftermarket universal. I like the following One-for-all model pretty cheap on ebay for open box models:
