I am not able to access developer settings on my LG Classic Flip. The codes don't work. I do not have a filter.

Please advise.

    A) Maybe your phone came with a filter that you are not aware of.
    B) If ##228378 doesn't work, try *#546368#*125#

        Atusb Depends on the filter, but even if a code works, it usually won't let you change too much. You won't be able to enable debugging etc.
