Same with android phones ...

Only if you've let Apple/Google have your data (I don't)

I can't remember the process fully, and I'm not going to wipe my phone
just to find out, but when I upgraded from Nexus5X to Pixel3 there was
an option to transfer apps/data between them using a USB-C to USB-C
cable, possibly initiated by tapping them back-to-back for NFC.

I don't know if this works on Samsung/Huwaei/OnePlus/etc phones, or just
Google's own devices.
