[Bug 1426115] Re: Screen timeout for system event (e.g. notification) needs to be a shorter duration than the standard inactivity timeout

 

u-s-c change available in silo 30
based on conversation with alf, this bug won't be closed based on the u-s-c changes alone.
We need components to employ this change in order to get the benefit

excerpt from alf mail

What's missing
--------------

* Other components that emit notifications and turn the screen on need
  to use reason 'notification' (integer value 4) to take advantage of
  the reduced timeout and proximity behavior.


* Phone calls display an accept/reject prompt, but proximity is not
  enabled for this prompt, so one could inadvertently reply to a phone
  call (although it requires a slide gesture, which makes it more
  difficult). I have an MP [1] that tries to improve this in powerd,
  but has a few drawbacks:

  - If the proximity sensor is covered when a phone call is received,
    the screen turns on momentarily before turning off again.
  - If the screen is already on, proximity is still enabled.

  For SMS messages we avoid these issues by handling everything inside
  USC. We could go the same way here by introducing a new reason 'call'
  for turning the screen on. I would recommend against this though,
  since we would be adding even more complexity and inelegance to a
  system that's already broken design-wise.

  Screen timeout for system event (e.g. notification) needs to be a
  shorter duration than the standard inactivity timeout

Bug description:
  When receiving an SMS notification or a calendar event the screen is
  left on for the full min or more as set by the user. This is not
  necessary and not how other phones behave.

  I would suggest 15 secs and go direct to suspend.
