[Bug 1587367] Re: Brightness toggle fakes brightness changes

 

Bug 1564342 seems to be unrelated: that is about “the rest of the
screen”, that is, the part outside the menu, on a tablet or PC where the
indicator doesn’t take up the whole screen. Your problem here seems to
be that on a phone, there is no “rest of the screen” — the screen is
covered by a black menu where brightness changes make little visible
difference.

Possible solutions include:
a. Nothing — the change in brightness of the text is enough.
b. Remove the brightness slider from the indicator menu.
c. Make indicator menus not black.
d. Make indicator menus full-screen only if they contain at least a screenful of stuff, which this one doesn’t.
e. Make this particular menu not full-screen, as a special case.

I would go for (d), but I guess this is up to Paty.

Title:
  Brightness toggle fakes brightness changes

Status in Canonical System Image:
  Fix Committed
Status in Ubuntu UX:
  New
Status in indicator-power package in Ubuntu:
  New

Bug description:
  When the display brightness is configured from settings -> brightness
  and display, while sliding the slider the user gets a preview of how
  it will look like the chosen value.

  Contrarily, when the brightness is controlled from quick settings,
  since the whole screen is black, the only clue is the brightness of
  the white text around.

  In Android, this is solved by making this screen transparent so the
  user can see the effect of using different values while sliding.

  Product: bq Aquaris E4.5, E5 & M10
  FW version: OTA-10.1
  HW version: MP

  STEPS TO REPRO:
  1. Pull down upper quick settings and check how screen is blackened 
  2. Now from battery toggle change screen brightness

  Actual Result:
  User can not know in advance what their chosen setting will be like

  Expected Result:
  Screen brightness changed from upper quick settings should work the same as brightness toggle in settings
