> wireless file transfers between Android and iOS being completely impossible at the moment

P2P proximal wireless transfer, sure, but there's half a dozen apps on your phone that'll let you punt a document, a photo, an invite to someone on the other phone OS platform.

Maybe I'm an edge case, but probably 90% of my Airdrop usage is between my own devices, so the platform taking care of the authentication story is of more utility than cross-platform transfers. If someone isn't on iOS I'll just send them the file on Signal since, if the source is my phone in the first place, it's probably not a huge transfer anyway.

That's exactly my point: Apps – which users have to install, which requires an Internet connection.

Also all of them routing data through some centralized server, often not end-to-end encrypted.

Approximately none of the people that I've Airdropped photos to in the past have Signal installed, and even if they do, there isn't always an Internet connection available. Airdrop also sends the original photo including all metadata and resolution, which is another big reason I like it.

On top of that, I've Airdropped photos to complete strangers (e.g. if I managed to get a nice shot of something on a tour) with which I didn't have any desire to exchange numbers, and I just would not have been able to send the photo to Android.

Comments like this are one of the few things that can make me jealous of Apple users. I just can't stomach how locked down the platform is as a developer. Android is also getting worse though.

This also roundtrips to the internet, which is slow and expensive compared to a LAN transfer.

You also can't attach files >100MB in Signal. No transferring an installer .iso.

Yeah, via their server, which means it's slow even if you have wifi, requires valuable data credit if not, or it requires the installation of a companion app on the other device and putting the other device in the same network.

The biggest point for me is privacy. I don't want to upload private data to some server just to send it to another device that's next to mine.

Most quality apps should be e2ee right?

Do you have an example for such an app? I don't know anybody using 3rd party file transfer apps. Usually files are uploaded to some cloud service (iCloud, OneDrive, ...) and then shared with a link if they can't be sent via messaging apps like WhatsApp or Signal.
