Hello, welcome to the Community, and thanks for reaching out pertaining to Smart View having an audio-video delay or lag. The first thing to try is clearing your device's cache partition:
 - Power off your device.
 - While the device is powered off, simultaneously press and hold the power and volume up buttons. 
 - Once the Samsung logo appears, release both buttons. Your device should boot into recovery mode. 
 
 Using the volume buttons to navigate and the power button to select: 
 
 - Navigate to "wipe cache partition" and press power. 
 - Select yes to confirm. 
 - Navigate down to "Repair apps" and press power. 

It is also possible a third-party application is interfering with Smart View's functionality. You can determine this with Safe Mode: https://www.samsung.com/us/support/answer/ANS00062983/

Lastly, try a factory reset, provided you back up everything you wish to not lose prior, and see if this helps Smart View's function: https://www.samsung.com/us/support/answer/ANS00062029/
