Re: Can't mirror Samsung S20 screen on Roku Premiere 3920RW using Smart View or Windows

Hi,
I am having trouble screen mirroring from a Samsung s20 fe to roku tv 6506X model number RTRU5829-CA.  I bought the TV in November 2022 new but did not open it until a few weeks ago.  The screen mirroring feature never worked. 
There is no screen mirroring selection under system even after a system update done from a USB downloaded file.
When I use the screenshate app on my Samsung s20 fe,  the roku tv appears when I click on it there is a message to restart the tv or unplug and plug in the tv 
 I tried that numerous times and found that nothing happened. 

I do not have wifi, I just want to use the tv for screen mirroring. 

Thanks,  Colin

@Colint63,

Thanks for the extra details!

I just wanted to dig in more, based on your statement that you don't have the option for screen mirroring on your Roku TV, right?

Or you're able to access the feature, but it's not visible on your mobile device.

Please keep us posted!

Thanks,
Rey

It is not on my Roku TV under system where it should be. I use rhe app screenshare on my Samsung s20 fe.  The roku tv appears but no connection is made.

Thanks,

Re: Can't mirror Samsung S20 screen on Roku Premiere 3920RW using Smart View or Windows

A few things:

1) All RokuOS devices support screen mirroring (Miracast) and should have a Settings/System/Screen Mirroring menu option.

2) However, there is a longstanding known issue that happens with some brand/model RokuOS TVs that results in the Screen Mirroring menu option (and functionality) missing.

3) You never mentioned whether you attempted a Factory Reset (Settings/System/Advanced System Settings/Factory Reset) - considering the missing Screen Mirroring menu item, you should try this at least once to see if that resolves it (Roku CS will require it anyway)

4) I notice your RokuOS version is 12.5.0-4176 - OS12.5.5-4174 has been out for 2 months now, you may want to manually check (Settings/System/Software Update/Check now) or check again to see if there is a new USB firmware image (with OS12.5.5).

5) Connection to WiFi (modem/router/gateway) is not required for Miracast ("Screen Mirroring") as it uses WiFi Direct (a direct peer to peer connection between the two devices) to establish the connection, and your case continue it.

6) The issue isn't WiFi or the lack of it - the issue is likely either a corrupted/missing Miracast middleware module (RokuCast 2.0.3) in RokuOS, a bad firmware install, or a firmware bug in that particular model's firmware - either way you need to push Roku on this (after you try a Factory Reset at least once).

7) You might consider contacting them more directly:  https://support.roku.com/contactus/contact-options.
