[Bug 1260986] Re: brightness not remembered after screen dim

 

I can reproduce this bug on n4 with firmware in dev channel rel 194.

In my current test, my proposed branch in bug #1287599 can fix this bug,
too.

I'll make this bug fix committed if the proposed branch there is
approved and confirm still can fix this bug.

Title:
  brightness not remembered after screen dim

Status in “indicator-power” package in Ubuntu:
  Confirmed

Bug description:
  If I am in a dark room and using the phone, I like to move the
  brightness down to the dimmest value via the indicator. If I'm using
  an app that requires concentration (eg, playing Sudoku) the screen
  might dim even further while I'm thinking (somewhat odd in and of
  itself, but this is a visual cue that the screen is about to blank, so
  'ok'). If I click within the app, the screen is brightened not to the
  value I selected for the dark room I am in (ie, the dimmest), but to
  some other brighter value.

  Interestingly, if I adjust to the dimmest setting and let the screen
  blank, when I unblank, the screen brightness setting is remembered
  thereafter (ie, I can play sudoku, let the screen dim, touch the
  screen and then it is at the brightness I previously selected).

  What seems to be happening is that the indicator dims the screen, but
  the value is not actually saved until screen blank and tapping the
  screen after screen dim before blanking resets it to the previously
  saved value (ie, not the one I just set via the indicator). Performing
  various combinations of setting brightness, dimming, blanking, etc
  seems to confirm this.

  UPDATE: I'm not sure that the dimmest setting is actually remembered
  after screen blank after all-- I was sure that I witnessed this, but
  then last night it didn't appear to be working this way. Maybe there
  is another bug in play....
