Hi, I am A. Stevens here to help with your question!
There are a few different ways to transfer data from your Samsung to your new iPhone
The easiest would be using your Google account, if you have one.
Otherwise the other option would be to transfer the data using Samsung Kies to your computer.
then you would take that data and sync to your new phone using iTunes.
Are you wanting to trasnfer only contacts? or is there other data you want to transfer as well?
There are also some 3rd party utilities that make the transfer a bit easier.
Is a good software to use if you want to make it simple.
Hi. looking to transfer contacts, gallery photo`s, what`s app contacts if possible
I don't think that you can sync whatsapp contacts across platforms
Otherwise contacts and gallery photos can be done with the methods I mentioned above.
The simplest way would be to use a google account.
Or if you don't mind using a paid solution, the wondershare program I mentioned would be great.
That would even copy your SMS too.
