961927 - [DSDS] Out of coverage RSSI is not correct based on UX spec.

Status: VERIFIED FIXED

(Firefox OS Graveyard :: Gaia::System, defect)

Please refer to UX spec in bug 917705. When there is no coverage, there are 2 RSSI bugs.
1. None of the SIM RSSI use the icon with "x" on it.
2. When each one has data connection and once encounter no coverage condition, data call icon is still on top of RSSI.

* Reproduce Steps
1 Insert 2 SIM and one has data call enabled.
2 Enter no coverage area.

* Expected Result
1. Follow the spec, there should be "x" on RSSI.
2. Data call icon should be removed when there is no coverage.

* Occurrence rate
100%

Bug 943227 is different than this one because it's focus on whether both RSSI should have "x". And at that time at least SIM 2 RSSI has "x" icon but now both are just grey signal bars, no "x" icon.

Based on the provided logs, both sim cards were still connected to networks ("connected": true). The "x" icon only appears when there is no connected network and unable to make emergency calls.

Hi Arthur,

The way I verified that is dial call to both SIM cards, all directed to voicemail. Any suggestion for that?

[Arthur Chen [:arthurcc][inactive after 6/30]]

I found that it becomes unconnected when you keep it out of signal range for a period of time. Edgar, do you know how it works in detail?

Comment 8

[Enpei]

I wait for 5 mins and make sure no MT can be received, still no "x" and data call icon is still there. It's really strange, I don't remember it took so long on bug 943227.

Hmm, strange, from the log it seems device still connect with network.
Not sure what happen here.

Hi Enpei, could you help to capture radio log as well?
adb logcat -v threadtime -b radio -b main > foo.txt

Thank you.

Hi Edgar, it's hard to do so while I shield device, if I attach USB to device, it will connect to network.

I think I found the point. From the log you provide, it seems the the sim card with data call established will not report status change when device is out of coverage. That is why I only see network is connected.
So if there is no data connection on both sim, the behavior is correct right?

Comment 13

[Edgar Chen [:edgar]]

Hi Sam,

We found the if device is out of coverage, the sim card with data call established will not report status changes, so that gaia doesn't show the correct icon. 
Could you help to check about this?

Thank you

Hi edgar,
okay,but I need the log with -b radio.

Time stamp 16:29~ 16:34. Unable to MO emergency or normal call at that period, yet icon is still not out of coverage and even with data call icon.

we should check gecko first.

Thanks, I will check gecko side.

Hmm, I think it is caused by below error,

[Edgar Chen [:edgar]]

Hmm, I found even gecko report correct status, there is still no 'x' on signal bar.
So I am going to file a separated bug for gecko part, and keep this bug tracking on Gaia part.
Thank you.

Comment 20

[Arthur Chen [:arthurcc][inactive after 6/30]]

It seems the "x" icon only appears in a very limited condition. Based on the code, it appears when voice.connected is false, emergencyCallsOnly is false, and voice.state is "notSearching".

Comment 21

[Arthur Chen [:arthurcc][inactive after 6/30]]

After confirmed with Edgar, the condition should not exist. When voice.state is not "registered", emergencyCallsOnly should always be true.

UX,

Please provide your guidance on the bug.
