BuildID 20131112040207
Version 28.0a1

STR:
1. Boot up device
2. Connect to WiFi
3. Load settings app, wait for Airplane mode toggle to enable
4. Tap airplace mode toggle
5. Wait a few seconds for "Disconnected" in Wifi region and "SIM Card not ready" in Carrier regions
6. Retoggle the Airplane mode
7. Wait for SIM to come back on

Observe Wifi settings - Wifi logo will come on in status bar but data is not active (try to navigate to a URL).
Tapping into Wifi in Settings app will scan a bit and then cancel, turning off WiFi.


Apologies but I've run out of time to get a clear regression range on this as I'm in my 11th hour of the day but I think it is fresh today.
The automation was broken for a different reason so the best range we can get from automation is around 5 nightly builds.

Could be caused by bug 921620's landing. A regression range will help confirm that.

The push log seems to strongly indicate that this is a fallout from bug 921620.

Sure

I think this bug share the same cause as bug 938044.

[Vincent Chang[:vchang][changyihsin]]

Hi Zac, may I confirm the issue here. After step 7, the wifi connection should come back to connected state and you can browser the internet using browser without the problem, am I right ? After that, if you turn off the wifi, we expect that the 3G data connection should reconnect automatically. But you find that 3G data connection doesn't reconnect, and you can't browser the internet. If it's the case, the should be duplicated as bug 938004 as Chuck said in comment 7.

Comment 9

[Zac C (:zac)]

Yes that's correct Vincent.

Comment 10

[Vincent Chang[:vchang][changyihsin]]

per comment 7~9. This should be a duplicate bug.
