which tv model first tell that ...if it's Samsung tv and both tv / mobile connected to same wifi then only it will work...otherwise you have to download anycast from play store to mirror screen
If your smartphone or tablet isn't connecting, it is likely due to one of the below reasons:
Your smartphone or tablet is on a different or old operating system. Some non-Samsung devices do not have full compatibility with Samsung TVs. Most Android devices should be able to mirror effectively, but other devices such as Apple's AirPlay are designed to be used with Apple TVs and may have limited functionality.
In these cases, you may be able to find a third party app that will connect the two, or can try using an HDMI cable or using a separate streaming device.
Both devices do not have screen mirroring switched on. You need to have the mirroring connection to be open on both your smartphone/tablet and the TV for the mirroring to work correctly.
We request you kindly reset the device and try again:
1)Reset the device: settings >General Management > Tap on Reset. Note: Before reset make sure to have back up of the data via Smart Switch Mobile App (Install Smart Switch App > Open > Click on Memory Card Icon >Back Up option > Choose the data for Back up > Back Up).
If the issue still persist, kindly register your concern in Samsung Members app (Samsung Members app > Get help > Feedback > Error report/ask question). Note: Please send device log files within 15 minutes of issue occurrence along with the exact issue details.
