[touch] Mobile data connection drops, and doesn't automatically reconnect

Taking a look at output of ofono scripts it seems all is good on that side: the modem is attached but the context has not been activated by NM.

info: the logs were taken while the bug was "active". And it still is :)

This sounds like the symptom I described on bug #1565717

Status changed to 'Confirmed' because the bug affects multiple users.

@faenil - I think I read on IRC that your machine lacks MAC addresses and so forth, for $reasons. Can you confirm this bug on a stock device?

@John: IMEIs and MACs are correct, now.

(And the bug was there before the inconvenience happened)

I'm able to reproduce this on arale ( rc-proposed, 334 ) by either toggling cellular technology ( 2/3g -> 2g only, and back ), or by putting the device into a faraday cage.

This is partially a regression in 1.1.93 ( we dropped a related patch ), and partially a day-one problem.

I have what looks to be a promising fix, but would like to discuss with upstream before I land it in the silo.

I experience this frequently on the Pro 5 as well. Sometimes when I pull down indicator for mobile it shows 3G or 4G, but shows no connection on the top indicator bar (see attached image).

The same Tomas reported occurs also in krillin after OTA11

Happens at work all the time, I work in a fridge, while in my pocket it should loose connection time to time because of the area. But then comming outside at lunch it has stopped trying to connect - must toghle airplane mode to get it to try again.

Can we have a retry connection triggered on unlocking the phone, if the device gave up trying to connect?

I'm on mx4 ota11.

Same problem here. But Iwant to add that when I switch off Mobile data (at night) and in the morning to "on" again, I have to switch it once more "off" and "on" to connect again (OTA-11 on E4.5).

Has this bug actually been fixed properly?

On Meizu Pro 5 with OTA-14 I still experiencing mobile data connection drops and the "indicator schizofrenic" very often. Am I the only one?

You are not the only one. I have no idea what was actually fixed and released regarding this bug, because nothing has changed for me. My Pro 5 has serious issues with both mobile data and wifi. It seems it can't reconnect properly once a signal is lost. I probably toggle airplane mode 5-10 times a day to reconnect. Indicator comes and goes and doesn't seem to have much to do with the actual data connection of my phone.

One thing I wonder though is if this problem is more common on the Pro 5 than on other devices and if it is related to which operator or cellular network you are on. I did a quick poll on G+ (https://plus.google.com/107122765209471240742/posts/9ESqWr35RSs?sfc=true) to see how many users had frequent connection problems. It turned out that about 50% of users have no issues whatsoever with mobile data or wifi. Only 5% had frequent mobile data connection issues, so that can explain the low priority to this bug.
