Description:
When the user opens the Ringtones or Alerts list, they are presented with a black screen for approximately 3 seconds, and then a white screen for about 2 seconds before the list finishes loading.

Repro Steps:
1) Update a Flame to 20150519010201
2) Launch the Settings app
3) Navigate to Sound
4) Select Ringtones

Actual:
The app displays a blank black screen and then a blank white screen for several seconds before the list properly loads.

Expected:
The app loads the list quickly, and possibly displays a spinner or progress bar to indicate progress.

This issue DOES occur on Flame 2.2, 2.1 , and 2.0 builds.

Note: The loading delay in 2.1 and 2.0 does not seem to be quite as long as it is in 3.0 and 2.2 builds, but is still around 2-3 seconds long.

NI media component owner to take a look, could be a settings issue.

I tested it on master, and while I do see the blank white screen and the blank black screen, it only lasts about half a second until I see the ringtones list view.  Does it show the delay only when other apps are loaded in the background?  if so this could be a variant of OOM issue.

This issue is more severe when occurring on a device with 319MB memory, but I am still seeing load times of 2.5 - 3 seconds on a device with 512MB memory.  This issue does not require other apps to be open.  If you just navigate back and forth from Sound and Ringtones several times, the issue occurs about half the time.
Flags: needinfo?(mshuman)
Ah, I didn't know that I had to navigate back and forth from Sound and Ringtones. I do see that about 1/4 frequency the loading of 'Select Sound' page is delayed.  I feel this is sort of connected to the Bug 1116732 that we never found out its underlying reason. nhirata_, who should we ask for the settings app type issues?  Or should we talk to the media folks instead?
Flags: needinfo?(nhirata.bugzilla)
Settings is kinda scattered.  I don't think we have anyone person assigned to it for 3.0 settings.

We have had white flashing in settings since 1.x time frame.  bug 840232

Having said that I think we should probably profile this bug to see where the slowness occurs.

Tried it, but profiler fails probably due to Bug 1167230. will retry once it's fixed.
