Care to share your moving from Apple to Android experience?

I transferred from iPhone 6 to an S7 Edge and never looked back. Apps like whatsapp, instagram, etc. all [can have the ability to] backup your data in the cloud for a situation like this.
I now own an S9+ and still have all my whatsapp messages from my old iPhone 6 on this new phone.
Now, for music, it's a different story. If you bought each individual song off of iTunes, then yeah, you can't bring them over to your new phone, but if you have a subscription like Spotify or even Apple Music, then yeah they'll work on your new phone. Hope this makes your transition easier :D
