Because Bluetooth is sooooo slow yawn
Edit: And I already tried OTG. Its slow as fuck because of the USB 2.0 bottleneck makes it take 3 hours whereas Quickshare would’ve taken like, idk maybe 15 minutes or less. Ironically wireless is faster, but I also need it to work for non-certified / custom roms.
The last time I used bluetooth to send files from device to device was in high school in the 2000s. It was painfully slow then, too.
These days I use KDE Connect to link my PC and phone.
What’s your specific use case?
