all the other models of asha got an update recently by which we can reduce the brightness of the screen....but why no update for nokia 302 still and y its left out.........
There is a new SW update for Nokia 302 which is currently being rolled out (I will make a separate post about that to the Software Updates-section later), but AFAIK a manual display brightness option is not included. I will try to forward your feedback about this inside Nokia. It's true that several device models recently got this option via SW update.
I made a post about the new SW update (14.78) to here: http://discussions.nokia.com/t5/Software-Updates/N
