There’s a random tv on my remote app. Any reason why this is possible?

How close are your neighbors? Do you share internet? 

A warm welcome here in the Roku Community, Ichikaa.

I'd be happy to dig deeper into the unexpected ONN Roku TV prompt on your Roku mobile app, and I appreciate you reporting this. 

Firstly, I would like to gather further information about this to assess your concern better and provide you with the most accurate resolution. Kindly let me know the following:

• Have you paired your Roku mobile app to an ONN Roku TV before?
• Are you connected to private/personal Wi-Fi?
• When did this randomly appear?

I'll be looking forward to your response so I can find you the best resolution possible.

Best regards,
Carly
