Hello Chiragk! There are two way : 1. Turn ON your smart TV, and then in your device there's a feature called 'Smart View' Turn that ON, you'll find it in Notification center(pull down the notification center and search for it.) Once you find it you can easily get connected to your samrt TV.
2. Open Settings >> Developer Mode >> Scroll down Enable "Wireless certification". To turn on developer mode : Go to Settings >> About phone >> Software info >> click 7-8 times repeatedly on 'Device Build No'. I hope this may help you. If it worked let me know.
Nevertheless, there's one more option I can share. Download "Google Home" app from playstore As you have Smart TV so it must have got Wifi & Hotspot connectivity. Now, in your A10s turn on Mobile hotspot >> Connect your Smart TV with your device hotspot >> Open Google Home app. This app will allow your device to screen mirror to your Smart TV. I hope this method may work. let me know.
If it worked out for you. Ensure that you tap on the 3 dots right corner of the comment and click "Solution accepted". It will be very kind of you & helpful to me.
Please be informed that smart view feature is not available on your Samsung device. However, Samsung is rolling out updates time to time for the devices and it totally depends on the availability and compatibility of the device with the same update.
