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

I'm also having problems with multiple Android devices. On 2.4GHz Wi-Fi, the ROKU will appear in SmartView, but not when ROKU is connected to the 5GHz network.
With Windows and Apple devices, this problem does not exist.

Model: 3940EU2 - ROKU Express 4K
Softwareversion: 12.5.0 - Build 4178-E4

Hi @Andy_AT,

Thanks for getting in touch, and welcome to the Roku Community. Have you seen this behavior happening before? Also, in addition to the details you've provided. Could you also share with us the information below?

  • Roku device model, serial number, device ID, and software OS/version (these can all be found in Settings > System > About) mobile device brand, model, and OS
  • tracker ID when this issue occurs (when you see this issue occur, press the Home button 5 times, followed by the Back button 5 times, and provide us with this ID).

We look forward to hearing back from you.

Regards,

It is my first Device!

I friend uses ROKU 

I want to buy 30 ROKU Devices for a School and want to test everything first 😉
there would be no need to buy the 4k version, when i can not connect ROKU with the 5GHz WLAN.

It seems there is no solution for this. I realized yesterday that my Roku Premiere 3920RW was updated, but i didn't had time yet to test again.

 

Can't mirror screen from any Android or Windows device. It only works with apple devices.
