Upgrade Your Streaming Game: How to Cast to Roku TV from Android

Streaming content on the phone is undoubtedly convenient, but there’s something special about watching it on a big screen. Luckily, with the casting feature, you can project content from your phone or tablet to a nearby TV. In this article, we’ll guide you on how to cast to Roku TV from Android device using a very simple method. The good thing is this method isn’t limited to Roku TVs but also works on any TV with built-in Roku.

So, let’s get started without any delay.

Casting Vs. Screen Mirroring

Roku TV uses the “Screen Mirroring” feature instead of “Casting”. Although both terms are used interchangeably, there are some key differences. When casting, you can only watch content available from a mobile app that specifically supports casting. At the same time, screen mirroring allows you to view content from any app installed on your mobile device.

With casting, you only see a playback of the selected content, while screen mirroring shows the entire screen of your mobile device, including buttons and menus. While casting allows you to use your mobile device or your Roku remote for control, screen mirroring requires all actions to be controlled on your mobile device. Casting is supported on most mobile devices, but screen mirroring is limited to compatible Android and Windows devices.

Additionally, once playback begins, casting allows you to use your mobile device for other things or power it off completely, while screen mirroring requires your mobile device to remain powered on for the duration of playback.

Preparing for Casting

A. Checking for Roku TV compatibility

Most recent generations of Roku TVs and Streaming Players running on Roku OS 7.7 or later support screen mirroring. However, there are some notable exceptions. To check your Roku model, go to Settings > System > About. 

  • Roku Express – 3960, 3900 and 3930, all support screen mirroring. 3700 being an old variant, does not support this feature. 
  • Roku Express+ – 3931 and 3910 both support screen mirroring, but 3910 has this feature on the HDMI output. On the other hand, 3710 does not support this feature at all. 

Check the official Roku comparison page for a complete list of devices that support screen mirroring. 

B. Updating Roku TV And Android Device Software

In some cases, if you’re using an older version of Roku OS, you may not be able to access screen mirroring. Here’s how to check and update your Roku software. 

  1. Go to Settings by pressing the Home button on your remote and then looking up the Settings feature. 
  2. Now, select System
  3. Go to System Update

VI. Troubleshooting On How To Cast To Roku TV From Android

A. Common Problems and Solutions

Bad performance

This issue is mostly caused by AP (Access Point) Isolation. Some internet routers have it enabled by default for security reasons. Refer to your router’s manual to learn how to disable this feature.  

Poor Video Quality

If you’re facing poor video streaming, it’s likely because your Android device is too far away. Ideally, your Roku TV and the Android device should be within 4 meters (or 15 feet) of each other. Also, these devices shouldn’t be 4 meters (or 15 feet) away from the router. 

Low Volume

Are you experiencing a low volume when you cast your screen, and you’ve tried changing the volume on your TV and Smartphone, but nothing seems to work? There is one other solution – the Google Home app. Here’s how to troubleshoot this issue: 

  1. Download and install the Google Home app
  2. Launch it. 
  3. Tap Media and adjust the volume. 

B. Tips For Improving Connection And Performance

  • Restart your Roku and Android device
  • Make sure your Android device has enough power to provide an optimal Casting experience. If the battery is too low, this feature may not work at all. 
  • Check to ensure both your Roku TV and Android device are connected to the same Wi-FiWi-Fi network. 
  • Your Roku TV and Android device should be as close to the router as possible. The closer they are, the better the signal quality, which translates to better video streaming quality.
