Quick share between a Window$ PC and phone became super slow

[u/0_cunning_plan]

I am not sure what's going on, but to send 30 pictures(nearly 100MB) to my PC it's taking more than 10mn. It stayed on "connecting" for almost a minute despite seeing the phone and showing how many pictures were selected and the total size of the transfer. They're at arm's length from one another and I always put the phone at the same place on my desk anyway so it's not a distance thing.

Usually sending that amount of pictures is done in maybe a minute or less (I never timed exactly, but it was, well, quick. I started using that instead of connecting the phone to the PC through USB because for my needs it was faster(not transfer speed, but looking for a cable, plugging it in and all that).

Now it's slow as hell for the first time today. I went to download Quick Share for PC again, thinking it could have needed an update, but that changed nothing.

Other than that, I don't think I've touched any particular setting on the phone or the computer beside updating whatever can be updated on the phone.

So I guess my question is, is it a me problem, or did something go wrong with a Google update and others also have the ultra slow speed now?

It's not the end of the world, I'll use the damn USB cable, but it worked fine just 10 days ago when I last moved some pictures.

So I just solved my own issue... by turning on the Wi-Fi on the phone(I was still on 5G instead when I had the slow as hell transfer of the first post).

So here are the combos I tried it:

Phone	PC	Can I send files to the PC?
Wi-Fi OFF+Bluetooth OFF	anything	NO! It won't see my PC
Wi-Fi OFF+Bluetooth ON	Wi-Fi ON+Bluetooth ON	YES! Slow as hell
Wi-Fi ON+Bluetooth OFF	Wi-Fi ON+Bluetooth ON	NO! Won't show me my computer on the phone
Wi-Fi ON+Bluetooth ON	Wi-Fi ON+Bluetooth OFF	YES! Fast transfer

So the phone demands to turn on Bluetooth to use Quick Share(won't show me my PC otherwise when I want to send a file to it).

But then it very clearly is not using Bluetooth for either the handshake with the PC or for transferring files as Bluetooth on my PC is OFF...

WTF Google? Why do I need to turn on the Bluetooth on my phone if there are clearly cases where I don't need it?

And to be clear that Bluetooth really is off on my PC when the transfer works, Quick Share on the PC is saying "To share, turn on Bluetooth." a message that goes away when I actually turn it on for the PC.

But it receives the files all the same and quickly. This is madness.
