Why is screen mirroring not working on my Samsung TV?
Screen mirroring isn’t working on your Samsung TV because your devices aren’t connected to the same Wifi. Sometimes, it’s because your TV is using the wrong input settings. And in other cases, there’s a glitch on either of your devices.
Screen mirroring not working on Samsung TV: 7 fixes
#1: Ensure that both devices are connected to Wifi
Before you try to fix anything on your TV or phone…
Check if both of your devices are connected to the same Wifi network.
See, mirror casting uses Wifi to connect your phone to your TV.
So if they’re not using the same network, you won’t be able to cast anything.
“But I don’t know how to check which Wifi my devices are using.”
Don’t worry. I’ll teach you exactly how you can…
Check the Wifi network of your Samsung TV:
- Press Home on your remote control.
- This will let you access the Smart Home of your TV.
- Using the directional pad on your remote, click the Settings icon on your screen.
- Head to General > Network.
- Tap Network Status.
- Take note of the name of the Wifi your TV is connected to.
Now that you know which Network your TV is using, it’s time to…
Check the Wifi network of your mobile device:
For iOS users:
- Turn On your iPhone or iPad.
- Go to your device’s Settings.
- Find the option that states Wi-Fi.
- Read the name written on the right side of that option.
For Android users:
- Turn ON your device.
- Go to its Settings app.
- From the list, tap Connections.
- Tap the Wi-Fi option.
- Ensure that it’s toggled ON.
- Read the name of the network it’s connected to.
Remember that the Wifi’s name on your TV should also match the 1 on your mobile device.
But if you’re thinking…
“My TV isn’t connected to the Wifi yet. What do I do?”
No worries. It’s effortless to do that.

#2: Use the official SmartThings app
While most modern mobile devices already have a built-in Cast feature in them…
It doesn’t always work best with Samsung TVs.
Especially if you’re using a mobile device from a different brand.
So for maximum efficiency…
I recommend installing and using the SmartThings app to cast from your phone instead.
See, as an official application from Samsung…
It’s the best mirror casting app you can use for Samsung TVs.
Not familiar with SmartThings yet? Don’t worry.
Because I’ll guide you on how exactly you can…
Use the SmartThings app to screencast to your Samsung TV:
Step 1: Download the SmartThings app on your mobile device
Step 2: Connect your phone to your TV using the app
Turn ON your TV and open SmartThings on your phone.
When the app launches, tap the Add Device option on your screen.
SmartThings will now search for any Samsung devices around you.
So once a list shows up, select your TV’s name.
Note: If a PIN appears on your TV screen, simply input that same pin into your app. And that’ll automatically connect the 2 devices.
Step 3: Open your TV’s screen-sharing menu
Here’s how you can do that:
- Press the Source button on your remote control.
- A window called Connection Guide will appear on your screen.
- Scroll down to the Mobile Device option.
- On the right of your screen, select Screen Sharing (Smart View).
Step 4: Tap Smart View on your SmartThings app
This should mirror your phone to your Samsung device.
Now, if this also doesn’t work, you should try to…
#3: Restart your Samsung TV
Indeed, Samsung is 1 of the world’s most popular and reliable brands.
However, that doesn’t exempt it from catching minor technical glitches or bugs.
So if you still can’t use the screen mirroring feature on your TV…
It may have a minor glitch or bug in its system.
Now, although these terms can sound intimidating and all…
You can get rid of them just by…
Restarting your Samsung TV:
- Turn ON your TV.
- Press and hold its power button.
- Wait for the TV to turn OFF.
- Let go of the button once it turns ON again.
Now, check if this solved the problem.

#4: Reboot your mobile device
Like your Samsung TV, mobile devices can also glitch.
And when this happens…
Even the most common connections or functions on your device can stop working.
But similar to what you did to your Samsung TV, a simple restart can also remove these glitches.
So don’t worry too much and just follow along with the…
Steps to reboot your mobile device
For Android devices:
- Turn ON your phone or tablet.
- Press and hold its power button.
- Let go when a window shows up.
- From the list of available options, select Restart.
- Wait for the process to finish.
For iOS devices:
- Turn ON your iPhone or iPad.
- Simultaneously press the volume down and power buttons for 3 seconds.
- At the top of your screen, you’ll find the “slide to power off” option.
- Drag the glider to the right.
- Wait for the phone to shut down completely.
- After a minute, press and hold the power button alone.
- Let go when the Apple logo shows up.
- Wait for the phone to turn ON again.

#5: Use 1 device at a time
Most households have more than 1 mobile device lying around.
So it’s easy to make the mistake of trying to screencast to the same Samsung TV…
All while you’re using several phones or tablets.
But remember, the screen mirroring function of your Samsung TV is designed to work with only 1 device at a time.
So connecting different phones simultaneously can cause a conflict with the system.
And stop the screen mirroring function from working at all.
So bear in mind that if you’re living with other people…
It’s essential to clearly communicate which phone will be used to mirror your phone to the TV.
This way, you’ll ensure that only 1 device will try to send the information.
And your TV will clearly know which phone it should get the data from.
“But I’m only trying to cast using 1 mobile device.”
Then that might also be the 1 contributing to the problem.
And in cases like that, you should…
#6: Try casting with a different mobile device
In rare instances, the root of the problem might be the device you’re trying to cast from.
And the only way to determine whether or not this is the case is to try using a different device.
See, a phone or tablet might not be able to use the screen mirroring feature if:
- It’s too old.
- It’s not updated.
- It has a software problem.
So try connecting a different device to your TV.
And if possible…
Do it using the official Samsung SmartThings app I mentioned in the 2nd fix earlier.
And if your mobile device is the problem, this should fix the issue.
#7: Update your devices
Updates are crucial to any technological devices there are.
Because they allow gadgets to:
- Run efficiently.
- Access new helpful features.
- Stay protected from recent glitches and bugs.
And on top of that, updates also ensure that…
All of your device’s functions are working.
Because having outdated firmware or software…
Sometimes prevents even the most basic functions on your devices from working.
And that includes the screen mirroring feature you’re having trouble with now.
“Aren’t updates installed automatically?”
Most of the time, they do.
But that’s not always the case.
So it’s always better to manually check for updates on your devices.
And with that in mind, here are the…
Steps to update your Samsung TV:
- Tap Home on your Samsung remote.
- Head to the Settings on your screen.
- From the window that pops up, scroll down to Support.
- Select Software update.
- Tap Update Now.
- Follow the on-screen instructions.
- Wait for the process to finish.
After updating your TV, you should also…
Update your mobile device
For iOS users:
- Plug your device into its power source.
- Turn it ON.
- Go to Settings > General > Software Update.
- Turn Automatic Updates ON.
- At the bottom of your screen, tap Install Now.
For Android users:
- Charge your device and turn it ON.
- Open the Settings app.
- Scroll down and head to System.
- Select System update.
- If an update is available, proceed to install it.
- Wait for the process to be completed.
Bonus: Invest in a Google Chromecast
If you’ve reached this far and your TV’s screen mirroring function still isn’t working…
There might be something wrong with your device’s built-in screencast feature itself.
And in that case…
You should consider getting an external Google Chromecast instead.
Google Chromecast is a smart streaming device.
And its purpose is to help you cast media from your phone to your TV.
So with that in mind, here’s how you can…
Connect Google Chromecast to your Samsung TV:
- Plug your Chromecast into a power source.
- Grab its HDMI cable and connect it to the HDMI IN port of your TV.
- Ensure that your TV’s input is set to the HDMI port your Chromecast is plugged into.
- Download the Google Home app (iOS and Android) on your mobile device.
- Turn ON your phone’s Bluetooth and sign in to the app.
- Once you’re signed in, add Chromecast as a new device.
- Follow the on-screen prompts you see.
Now that your mobile device is connected to your Samsung TV…
Here’s how you can cast from your phone to the bigger screen
Step 1: Turn ON your TV
You can do this using the physical power button on your device.
Or through its Samsung remote.
Fun fact: If you’ve downloaded the SmartThings app, you can also use it to turn ON your TV.
Step 2: Launch any streaming service you wish to use on your phone
The most popular options are:
But if you want to broaden your choices…
I recommend visiting Google’s official page for Chromecast apps.
Because there, you can find all Cast-enabled applications that you can use.
Step 3: Select the episode or movie that you wish to play
If you wish to cast a game instead of a streaming service, you’re free to do so.
Step 4: Tap the casting icon
Most of the time, this will be located at the top of your screen.
And it’ll look like a rectangle with a diagonal Wifi icon on its lower-left corner.
Step 5: Select Chromecast from the list that shows up
After tapping the casting icon on your phone screen, a small window will pop up.
And it’ll show all the available devices you can cast to.
Now, ignore your Samsung TV’s name even if it’s on the list.
And you tap the name of your Google Chromecast instead.
Step 6: Enjoy your phone’s contents on the bigger screen
Just remember these steps every time you want to cast from your phone to your TV.
And you’ll be good to go.
