    Hello everyone ,
    my Lumia 640XL (Windows 10) is not opening the
    adjust brightness setting.When I upgraded my phone to
    Windows 10,at first it worked but after 1 -2 months it
    became non-responsive, I mean I push it a hundred times
    and it does nothing.
    Settings > Extras > Display (is doesn't even open).
    The phone has no other problems ,but that one is really
    annoying.
    Please give me your advice, I don't want to reset it .
    Thanks in advance

    Is your OS up to date? Any apps pending in store?

    Some settings seem to open when your phone is connected to internet -try that
