Signal strength and Data signal (3G/H/E) is not changing (I observed this during journey in train when signal strength is varying) while checking in after opening any app.
When checking this in homescreen, it's fine but when i checked this after opening any app i got this.
I have attached the images.check the top line (near signal bar). We will find the difference.
Tested on Flame : Nightly

Do you remember if the time changed? We are investigating a bug where the whole status bar freezes.

Comment 3

[kumar rishav (:rishav_)]

yeah..time too. Homescreen result is actual and correct .

Hi Gregor, has any progress been made on this? This issue is still occurring on v2.2, see attached video.

It's not 100% reproducible, but playing around with airplane mode and opening apps while it's being enabled/disabled seems to trigger this status bar freeze fairly regularly.

Comment 5

[Gregor Wagner [:gwagner]]

We fixed many issues around this. Was this reproduced on the latest 2.2 builds?

Comment 6

[pgravel]

Yes this is reproduced on latest 2.2 build.

[Michael Henretty [:mikehenrty][:mhenretty]]

Guillaume, can you take a look at this? Comment 4 seems to provide a starting point for STR.

We might need to land bug 1144126 to get more info from the reporter.

[Michael Henretty [:mikehenrty][:mhenretty]]

Guillaume, can you make a patch like the one from bug 1144126, but with logging enabled by default. pgravel can apply this to their builds and get the logging results for us.

Hi, this patch contains a logger for the status bar events. Can you please apply this patch to v2.2 branch and flash your phone?
Then try to reproduce the bug. When the bug is reproduced, please attach a logcat to this bug and I'll be able to enquire and see exactly what went wrong.

It took me some time to reproduce the issue. STR below

- Open email app
- Close the keyboard (not sure if that matters)
- Pull down the status bar and click on airplane mode icon
- Repeat above steps.

Hi Guillaume,
Soft reminder for the log provided by Anshul per comment 10.
Thank you!

Comment 13

[Guillaume Marty [:gmarty]]

Thanks! I'm on it. I see exactly what goes wrong from the log. I'm now looking into how to reproduce and fix it.

Comment 14

[Guillaume Marty [:gmarty]]

Simplified STR:
1. Open the utility tray
2. Quickly slide up the utility tray and push the home button at the same time

As a result, the utilitytraywillhide event will be triggered twice, resulting in an inconsistent behaviour.

r=me with the new test added (let me know if anything's unclear) and a new try build :)

[Anshul]

Guillaume, this patch doesn't seem to be applying cleanly on v2.2. Is there a v2.2 version of this patch?
