Transfer desks from one device to another

Hi there,
I’ve been using the AnkiDroid App on my Samsung tablet.
Now I got a new tablet from Samsung as well and want to transfer all of my desks to the new tablet. I already signed up but no matter how I don’t get my desks transfered to the new tablet in the app.
Could you please help me how I can transfer them?
Thank you!

You can export your collection, and the import the .colpkg file in the new device, or you can use ankiweb:
Old device > log in > Sync > upload to ankiweb
New device > log in > sync > download to ankiweb
