Just checked my backlight settings and the 5% option I have used for general use since I bought my FR255 at launch (great for checking the time during the night without getting blasted with too much brightness) seems to no longer exist? Lowest setting is now 10%. Anyone in the same boat? I assume it went away with the 12.23 update.
Although from my 955, my Sleep is still at 5% but if I open and try a press save i can only select 10% and up. Not saving though
