How To Connect Android 13, 14, 15 Phones to Smart TV and Mirror Screen Quickly

Screen mirroring your Android phone to a Roku 4K streaming device is honestly pretty handy for showing off photos, videos, or even apps on a bigger screen. If you’ve ever tried it, you probably ran into some weird hiccups or confusion, especially with different Android versions or Roku settings. Here’s a rundown based on real-world mucking about — because of course, these things don’t always go smoothly the first time.

Requirements Before You Start

An Android phone running Android 13, 14, or 15 that supports Miracast (or at least has the casting feature). Watch out, not all phones handle this the same way.
A Roku 4K device (like the Streaming Stick or Ultra), plugged into a TV via HDMI.
BOTH devices need to be on the same Wi-Fi network. No, you can’t do this over different networks or via hotspot — that’s asking for trouble.

Step 1: Set Up Your Roku 4K Device

First, hook up the Roku:

Plug your Roku into the HDMI port on your TV.
Connect the power cable and turn it on.
Switch your TV to the Roku input.
Follow the on-screen prompts to connect to Wi-Fi. Make sure the network matches your phone’s, otherwise, good luck.
Don’t forget to update the Roku software if it prompts you — sometimes funky bugs are fixed in updates.

Quick tip: sometimes on certain Roku models, the screen mirroring option might be buried a few menus, so poke around if you don’t see it right away.

Step 2: Enable Screen Mirroring on Roku

Now, get it ready to accept your phone’s mirror:

Hit the Home button on Roku remote.
Go to Settings > System > Screen Mirroring.
Choose Screen Mirroring Mode — pick Prompt if you want a pop-up every time, or Always Allow if you’re lazy and don’t want to confirm each time.

On some setups, this part can be flaky. Sometimes toggling the mode or rebooting the Roku helps — I’ve found that re-enabling this setting after a restart fixes weird connection issues.

Step 3: Access Screen Mirroring on Your Android Phone

This varies a lot depending on your device, but you basically want to toggle the casting or screen mirroring function:

Swipe down from the top of your Android screen to open the Quick Settings menu.
Look for options like Cast, Smart View, or Screen Mirroring. Some phones call it different stuff, but the icon is usually a rectangle with Wi-Fi waves or similar.
If not found there, go into Settings > Connected Devices > Connection Preferences > Cast. Just remember, on some devices, this step is cranky or hidden behind menus.

Pro tip: sometimes toggling airplane mode or toggling Wi-Fi off/on resets the cast menu if it’s acting weird.

Step 4: Connect to Roku

Here’s where it gets the most hit-or-miss:

Select your Roku device from the available devices list. If you don’t see it, double-check both devices are on the Wi-Fi and that screen mirroring is enabled on Roku.
If a confirmation pops up on your TV, accept it.

Honestly, I’ve seen on one setup it connected perfectly the first try, and on another, it kept failing until I rebooted the Roku. Weird how some things just refuse to work without a quick restart.

Step 5: Start Mirroring Your Screen

Once connected, your phone should start showing on the TV. To send specific content:

Open a compatible app (like YouTube or Google Photos).
Tap the Cast icon inside the app.
Select your Roku from the list, and the app should cast directly to the TV even if your whole screen isn’t mirrored — depends on the app’s support.

And if you want an easy way to mirror everything, just let your phone do its thing — though, don’t be surprised if it’s a little laggy or drops connection if your Wi-Fi isn’t perfect.

Step 6: Extend Your Display (Optional)

Not gonna lie, Android doesn’t natively support extending your display to Roku unless you go with third-party options like AirDroid Cast or SecondScreen. Just keep expectations low — most of the time, it’s mirroring, not extending.

Step 7: Stop Mirroring

When done, head back into your cast menu on your phone — or just press any button on the Roku remote. It should prompt you to disconnect or just automatically stop mirroring.

Sometimes disconnecting can be finicky, especially if your Wi-Fi gets jumpy. Rebooting both devices can fix it, but that’s overkill more often than not.

Extra Tips & Common Issues

Make sure both devices stay on the same Wi-Fi — it’s the most common problem.
If the connection keeps failing, restart your phone and Roku. Sometimes Wi-Fi just gets weird.
Update both your Android OS (check for system updates in Settings > System > About Phone) and Roku firmware (Settings > System > System update). Newer versions are often way more stable.
If your phone still can’t see the Roku, double-check that your phone supports Miracast — not all Androids do, especially older ones.

Summary

Make sure Wi-Fi is the same on both devices.
Enable screen mirroring mode on Roku (prompt or always allow).
Use your phone’s cast or screen mirroring feature.
Select the Roku device and accept connection prompts.
Enjoy your bigger screen — and don’t get frustrated if it takes a couple of tries.

Hopefully this saves someone a headache — because, yeah, the tech world loves to throw curveballs.
