Unable to move data from Samsung S8 to iPhone 16

I am trying to move data from Samsung S8 to iPhone 16. The apps do not show up after entering the code. I waited for 15 minutes. The apps did not show up. This is when using wi-fi.

When I use cable, I get error message that data cannot be transferred. And to use Smart-switch to move the data to Mac before transferring to iPhone16.

Either way, I have trying since 5-6 hrs with no success.

Is there any other way to transfer data from Samsung S8 to iPhone 16?
