Hi! @ayush7646,
Thank you for reaching out to the Roku Community!
We are happy to assist you with screen mirroring being unstable.
If there's an object obstructing or interfering with the wireless signal between the TV and the mobile device, the picture quality may be unstable or blurry when using one-touch mirroring or screen mirroring. Remove objects blocking the wireless signal between the mobile device and the TV to avoid this issue.
Please keep us posted on what you find out, and we will be more than happy to continue assisting you further.
Thanks,
Arjiemar
