No data for 1hr = Waze doesn't recover network connection

[RallyChris]

Waze has never told us how long it can cache data for. In theory for the iPhone and Android you are only limited by application storage limits. But I suspect that it is much lower (maybe a hold over from earlier supported devices).

Waze has only told us that it is designed to handle "short" outages.

[RallyChris]

This is a long standing issue. Waze has not handled data outages well.

I understand that Waze wants the data to be relevant for the time frame, but the client and server should be able to agree that the data being sent is "aged". And just use it for route analysis, and not real time traffic data. It should even attempt to hold this data over restarts.

That way roads in non cell range can get auto direction, turn restriction updating and also average speeds adjusted appropriately.

Yeah, this also happens when accepting a voice call. It has been happening since 3.0.1, where they made some improvements to the connection handling code.

I discovered a serious regression (for
me) in 3.0.1. (I was able to install an old 3.0.0 to make sure the
problem doesn't happen there).

What happens?
- I'm navigating/driving using Waze
- I accept a phonecall while I'm on 3G (which I usually am)
- 3G signals drops, iPhone switches to 2G
- Waze loses network (2G can't do data and voice at the same time ofc)
- After completing the conversation, the 3.0.1 version is unable to
restore the connection to the Waze servers (on either 2G/3G or even
when connected to WiFi). 3.0.0 works fine.

I know we made some changes in that area, so they might have caused this behavior. Let me check and get back to you.

I have the same with last version of Waze...

This looks like something completely different - you lost the GPS signal, not the data signal.

Hi Alan,

Can you please post the video?

I had this today after a call. Network dropped and didn't reconnect until a restart of Waze. I had HSDPA the whole time.

I don't see why there is this problem. Surely Waze temporarily stores the gpx tracks on the sd card ready for upload? Is it not able to do this during outage by design or?

Well, not necessarily us, but as with Facebook, our data is invaluable to them and is indeed where they will make their money. Personally, I don't have a problem with this, since it's not personally identifiable information, it's pretty much just a load of anonymous data.
Besides, we are also benefitting from the data as it's making the product better by also giving us the opportunity to edit the map better than if there was just aerial images.
