Description Antti Savolainen 2025-03-29 19:07:48 UTC

SUMMARY
Demonstrative video: https://www.youtube.com/watch?v=tGSKLpXycpI
When you're in a crowded area, the pairing tool gets spammed by no-name bluetooth devices. If your device is at midway point or later, it keeps bouncing around in the menu, clicking on it is hard and scrolling to find it is frustrating. Sorting named devices to the front would fix this. Fixed point scrolling would also be a good secondary fix to implement. 

STEPS TO REPRODUCE
1. Go to a crowded area
2. Open the bluetooth pairing menu
3. Scroll down the pairing menu

OBSERVED RESULT
The entries jump around and the named entries are everywhere

EXPECTED RESULT
All named entries should be at the top and the scroll should be fixed to the entry at the middle of the open view

How would this fix the issue? What if the device you're looking for is also a no-name device?

For this particular issue where the device you're looking for does have a name, that's what the search field is for.

But it does seem like a legitimate problem, so I think we need to think of a more general solution for it.

The named devices are more often the ones actually active for pairing. Not even sure what the non-named devices were in that list. Phones that advertise themselves but don't actually allow for pairing?
