I think this can't be true, not under kitkat. It is a bug.
When i was on old bootloader, and it was no problem to switch between 4.3 and 4.4 it was clearly to see: no glonass on kitkat, and instantly glonass-fix under jellybean.
Since I've got kitkat, i never had a glonass-fix, although i could see them.
