So yesterday I tested WiFi Direct against Quick Share and to my surprise (kinda) WiFi Direct was much faster than the latter
Tried sending a 1.21GB video file from a Galaxy S6 to a galaxy note 9
- WiFi Direct: 54.71 MB/s
- Quick Share: ~33 MB/s
OneUI can show network speed in real-time in the notification panel, that’s how I captured these numbers and they were very stable and I did it multiple times just to confirm.
Unfortunately samsung and all other OEMs have basically killed WiFi Direct, I can only receive files, they removed the option to send files through WiFi Direct on newer versions of android (I think A11 and later) a long time ago that’s why I can’t do this test in reverse (from N9 to S6)
I tried looking up for an app on Google play store, galaxy store, F-Droid that can send files using WiFi Direct but found nothing, that’s really puzzling for me, like why?! This standard is very old by now, it’s been on our phones for more than a decade and yet no way to fully utilize it?!
For the ones who don’t know WiFi Direct is a P2P connection.
I thought Quick Share was just WiFi Direct with a Bluetooth pairing step, so it’s surprising there’s a noticeable difference. But if you see that difference repeatedly, it must be there.
I thought so too, but I think it also tries to detect if you’re on the same LAN and transmits the data through that. I have some routing issues with my VPN and when I turn it on on either device, Quick Share just won’t work. Could be that routing the traffic through the router is slowing down the data transfer.
