I have four Rokus in my house and it’s like all of them have a mind of their own, they’ll turn themselves on, turn the volume up at down, even selecting apps and picking a show or a music selection, it’s seriously freaking me and my entire family out, how do I fix this?
Someone might be connected to your network and using the Roku mobile app to control your Roku devices. You might want to change your Wi-Fi password.
And change your Roku account password. When you do that, there is an option to force currently logged in apps off.
Should also add: Do you have kids? They could be pranking you.
