Warm greetings here in the Roku Community, @Boop69!
It is highly appreciated that you've reached out for support and we'd be happy to further assist you in utilizing the screen mirroring feature.
Before we proceed, it's important to note that you cannot cast the Roku mobile app from your Android phone to your PC or laptop. However, you can still enjoy your favorite channels and TV shows by logging into your Roku account on your web browser and streaming them from there.
Nevertheless, you can display content from your phone or tablet on a nearby TV with screen mirroring. Replicate, or mirror, the screen of your phone, tablet, or computer onto your TV screen. Display web pages, videos, photos, music, and more to your Roku® streaming device.

Let us know if you need further clarification and assistance!
Happy Streaming!
Best regards,
Carly
