I updated also my 2nd Tolino FW12.2 (Kitkat) to september release, and there the Brighness Toggle issue doesn't occur.
But...
With august version, if I changed the brightness level in Koreader, it was reflected also in other apps, like in the dictionary I am often calling from koreader.
But now, if I change brigtness in koreader, this change is reflected only there... and other apps stay on previous level (:-(
