You don't have to pair a phone to use it as a remote. When it comes to Bluetooth, it can be confusing. Some devices support streaming audio from them via Bluetooth and some support streaming audio to them via Bluetooth and I'm sure some support both options.
To use your phone as a remote, use the mobile app:
Roku Mobile App - Free for iOS® or Android™ | Roku
Devices that support streaming audio from them via Bluetooth (Bluetooth headphones):

Roku devices also support mirroring and casting that don't involve Bluetooth:

I have Verizon Fios for internet and for my main TV (it has a set top box). I added the Fios TV Mobile App to my phone (Android and my husband's iphone 8). I want to be able to "cast" or "mirror" the Fios Channel I am watching on my phone to my older model Sharp TV. I bought the Roku Express 4k+. It does not offer an option to "pair". The remote works and I get channels but I cannot pair it to my phone (or my husband's). So I am not able to use the screen mirror option on the Fios TV Mobile app. Additionally, when I search my Bluetooth for available devices to pair, Roku does not show up.
So my original question still is, do I need to get a Roku Streambar? I am thinking the Roku Express 4k+ does not allow for casting/mirroring from the Fios TV App.
Thank you for responding....but I do not want to use my phone as a remote, I want to be able to watch Verizon Fios TV on my other TV using Roku.
Thank you.
KG11, I tried to explain it as completely as possible. You don't pair a phone to a Roku device for casting or mirroring. Read the link I gave. All Roku devices support it, but not everything can be mirrored or casted. Stop going down the Bluetooth path; it's a dead end for what you're trying to do.
A better question to ask your fellow users is whether any of them have successfully casted or mirrored the FIOS TV mobile app from a phone. Verizon may also have some insight.
