We should get a scope here before we mark it blocking. What is the target time?

Comment 2

From partner: the receiving (MT) phone is expected to ring before the calling (MO) phone hears the 2nd ring
5 sec could be pretty close to 2nd ring. 
Can QA confirm again? Thanks

Ken, any idea if this could be a RIL issue ?

I can not reproduce this issue in Taipei. I wonder if this is a network issue? Could you test it in other network? Or Could you please provide logs for us. Thanks.

To Naoki for comment 8

There is at least a 2 second delay between hearing the ring and getting the ui for the call.  Sometimes up to 5. I don't think that's related to the network.

There is a 13 second delay from the time of the call to hearing the ring.  That might be network related.
I have not filed that bug yet.  Please investigate the issue with the delay from ring to ui.  I will investigate getting the logs for the delay in call connectivity in a separate bug.

I got the different test result. Device pop up incoming call right away when I heard the ring tone.

Hi Aknow, can you please analyze this bug? If you are not available for this, please let me know. Thanks.

Comment 12

[Joe Cheng [:jcheng] (please needinfo)]

could the difference be in the number of background apps when the call is coming in?
could you share what app are in the background during your testing? thanks

Comment 13

[Szu-Yu Chen [:aknow] (inactive)]

Yes, I will analyze the bug.


Naoki,

Are both MO/MT within the same operator network? If not, could you reproduce the issue on this condition.

>> Actual: 2 second delay, ringing occurs, 3 seconds later the UI appears
What do you mean "2 second delay"? At which moment, you strat to measure the delay. And the "ringing occurs" means the MT phone ringing, right?

Comment 14

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

As per the STR, this is after a reboot and unlocking SIM and screenlock.  Please see the attached video.

Comment 15

[Szu-Yu Chen [:aknow] (inactive)]

It might not be a ril issue I think. The issue focus on the long delay from MT call ring to UI.

Hi Patrick,
I remember you have done some imporvement on this topic. Do you have any idea?

Comment 16

[Patrick Wang (Chih-Kai Wang) (:kk1fff)]

Code of playing ringtone had been moved to system app recently, and it has become faster now. However, showing the UI needs to launch Comms app, it takes more time.

In my local test, even with music playing in background, the ringtone starts to play at almost the same time when the first ringback starts. I can't reproduce the 2 seconds delay, either.

Comment 17

[Ting-Yu Chou [:ting] (away)]

Two HTML files are loaded when there's an incoming call, first dialer/index.html, and then dialer/oncall.html. After index.html is loaded, dialer.js registers a handler for message "telephony-new-call", which opens oncall.html.

I am wondering:

- Can we load oncall.html only for incoming call?
- Is the fist "telephony-new-call" queued and delivered to dialer right after it
  registers the handler?

Will try to figure these out tomorrow.

perhaps Etienne can provide some insight on comment 17

Nope.
Eventually I think we'd like to direct system messages at attention screens directly, but it's not possible right now.

Yes.
We could also investigate setting the message handler without waiting for the "onload" event...

is Ting working on this at this moment or is it Aknow? Thanks

Comment 21

[Szu-Yu Chen [:aknow] (inactive)]

Unassign myself.
It might be a performance issue and not just the ril issue.

Comment 22

[Ting-Yu Chou [:ting] (away)]

Joe, seems :kk1fff is working on this, Thinker'd like me to figure out why UI comes up faster when there's no background app.

Comment 23

[Joe Cheng [:jcheng] (please needinfo)]

hi Patrick, are you working on this bug? Thanks

Comment 24

[Joe Cheng [:jcheng] (please needinfo)]

Etienne, wonder if you have some thoughts on this bug? thanks

Comment 25

[Patrick Wang (Chih-Kai Wang) (:kk1fff)]

I am focused on the case with music for now. But I will update this bug if I find anything related to this.

Comment 26

[Thinker Li [:sinker]]

We have moved the ringtone code to sysapp, @[e-mail] what is the version of your code?

Comment 27

[Joe Cheng [:jcheng] (please needinfo)]

Triage: team's working on bug 987022 to speed up incoming call rings. let's track bug 987022

Comment 30

[Naoki Hirata :nhirata (please use needinfo instead of cc)]

This is not a duplicate.  It's not the ringing that's the problem; it's the phone UI not showing.  The ringing happens for 5 seconds before the user has the UI to answer the call.

Comment 31

[Joe Cheng [:jcheng] (please needinfo)]

Etienne, this bug seems to be a dup of Bug 990003. 
do you have a preference on which bug you want to work on and dup one of it to the other?
Do you mind taking the bug? thanks
