### What You Need to Know
To facilitate a seamless connection between your Roku television and the Roku mobile application on your smartphone, both devices must be connected to the very same wireless network. This requirement is essential, as a mismatch between networks — even between different bands of the same router, such as 2.4 GHz and 5 GHz — can prevent recognition and communication. In addition, within your Roku TV’s system settings, there exists a crucial option allowing remote control by mobile applications. If this setting is disabled, the Roku app on your phone will be unable to detect or control the device. Therefore, prior to troubleshooting, it is important to ensure that app control is enabled on your television.
In situations where the official Roku mobile application has been successfully installed on your iOS or Android phone, but the app still fails to display or identify your Roku television, a series of systematic troubleshooting steps can help resolve the issue.

### Resolving Connection Issues with the Roku Mobile App
The Roku remote app is designed to work equally well across both Android and iOS platforms. When connectivity problems arise, it is best to begin troubleshooting with the most typical causes, then continue progressively through more advanced solutions as needed.
1. **Enable Mobile App Control on Roku TV**
Access your Roku TV menu and navigate through: *Settings > System > Advanced System Settings > Control by Mobile Apps > Network Access*. Here, you can select between two options: **Default** mode, which suits the vast majority of users, or **Permissive**, intended for complex or custom configurations. If this feature is turned off, the Roku mobile application will not function properly.
2. **Confirm Network Consistency**
Both your Roku TV and smartphone must not only share the same Wi-Fi connection but also align on the same frequency band. To verify the TV’s network connection, proceed to *Settings > Network > About*. From there, you can confirm which SSID (network name) the television is actively using and compare it with the phone’s connection.
3. **Adjust iOS Local Network Permissions**
For iPhone users, the operating system requires explicit permission for apps to interact with other devices across the local network. Navigate to your phone’s *Settings*, locate *Roku*, and ensure that the switch for **Local Network** access is enabled. Without this setting, the Roku app cannot establish communication with your TV.
4. **Verify the Use of a Private IP Address**
Connected devices on a home network typically utilize private IP addresses assigned via a router. Some setups — particularly those lacking a router — may inadvertently assign a public IP address to the Roku TV, restricting app discovery. To check, visit *Settings > Network > About* on your Roku TV. If a public IP is displayed, consider installing a router or consulting a network specialist to configure your environment correctly.
5. **Deactivate VPNs**
A virtual private network can reroute all internet traffic, including traffic from the Roku app. Such redirection may block the app from detecting your Roku device on the local network. Temporarily disconnect the VPN and attempt reconnection; once the Roku app functions as expected, you may re-enable the VPN afterward.
6. **Restart Devices**
Simple as it may sound, restarting often resolves otherwise stubborn issues. Restart the Roku television using its system menu, then fully close and reopen the Roku mobile app on your phone. This reset refreshes both devices and can clear minor glitches.

### Manual Connection as a Last Resort
If the above strategies do not restore connection, the Roku app does permit manual pairing via an IP address. To attempt this:
1. On the Roku TV, navigate to *Settings > Network > About* and note the device’s IP address.
2. On your smartphone, open the Roku application, go to the **Devices** tab, and tap the three-dot menu in the top left.
3. Select **Connect Manually**, enter the IP address copied from the Roku TV, and tap **Connect**.
This provides a more direct way of establishing a link when automatic discovery fails.

### When to Seek Official Roku Support
Should all troubleshooting measures — including manual IP entry — fail to produce a successful connection between the app and your television, contacting Roku’s official support service becomes the next logical step. By visiting the Roku Support portal, you will be able to choose from several assistance channels, whether self-help guides, live chat, or direct customer service.

### Common Underlying Causes for Connection Failure
The root reasons behind a smartphone failing to pair with a Roku TV can typically be traced to one of the following factors:
– **Mobile app control is disabled** on the Roku TV, preventing communication altogether.
– **Network mismatches** between the TV and smartphone, such as being on separate Wi-Fi networks or bands.
– **Permission restrictions on the phone**, especially with iOS devices, where local network access might be restricted.
– **Interference from VPN configurations**, which can block device discovery.
By systematically working through these potential obstacles, most users find they can restore connectivity and continue enjoying uninterrupted streaming.
