We're grateful to have you here in the Roku Community, @shrimbhu!
I appreciate you sharing your concern about the button responses on your physical Roku remote, and I'd be happy to suggest some steps to help you resolve this.
Please try pressing and holding the Back and Home buttons simultaneously for about 20 seconds to reset your remote. After doing so, pair it again to see if this makes any difference.
In addition, may I know if this happened prior to your latest software, version 13?
I'll be looking forward to your update!
Best regards,
Carly
