I am getting similar issues when I have waze running and I am listening to podcasts through my Galaxy Note 2 using bluetooth, I lose the ability to pause the playback until I close the waze app.

Hi there,

Same problem than jlmather except that if i quit waze, the problem still here. I have a Wiko Cink Slim with ICS 4.04.

I still use this excellent app but I have to put backlight prefs at 30 minutes to use it.... really annoying indeed...

Thanks for considering the problem.

I have a Sony Xperia S with the latest firmware, and the latest Waze version (both as of 23-Nov-2012). Even though "prevent screen lock" is enabled, if I change some of the options in Waze, the screen WILL lock after the phone's time-out period. If I close Waze and re-open it then all is ok, the screen does not lock. Some things cause this to happen (eg changing 2D to 3D), some things are ok (eg zooming in/out of the map). I know what to do when it happens, so I will still carry on using this excellent app, but it is annoying.

I am experiencing similar issue with newer 3.5.0.0 version where even through the 'Prevent Auto-Lock' is enabled, my EVO 3D still goes to sleep/locks ( I liked on the previous version that the phone would not sleep at all till manually changed to other screen or Waze closed); also when the phone is unlocked/wakes-up, the time on the phone is correct, but estimated time to reach the destination is off by about 5 to 6 hours ahead (or UTC +2).

Likely all of this depends on your specific stereo, what type of Bluetooth support it has, as well as other environmental conditions that can reduce or interfere with the bluetooth connection.

In all cases Waze should continue to send data to Waze, record your route, and generate points (as long as you don't stop for more than the Waze timeout duration and you have a data connection).

Once you 'turn off' Waze, end the Waze application, or stop for more than x minutes, Waze will no longer be active.


Thanks for your interest and feedback.

Looking at your list of observations above, when not streaming audio, are you able to get TTS instructions over Bluetooth when Waze is in the background [edit: and your iPhone locked]? I ask because this is the problem I'm encountering.

I hadn't thought to test all this whilst streaming audio - if I'm understanding correctly, you mean listening to music over Bluetooth whilst Waze is running?

I shall repeat my tests tomorrow morning with music playing over Bluetooth simultaneous with Waze running. Just for cross-reference, Waze closed, if I stream music from my iPhone to the car speakers then I hear music regardless of whether the music app is in the foreground or background, and the phone locked or unlocked.

If you have the setting to "always play to speaker" set to On in Waze, and are connected via BT streaming to your car, putting Waze in the BG will result Waze not outputting any audio, unless you are also streaming at the time, and then Waze audio goes out over BT. I think this may be an iOS limitation.

I had a bit more of a play on the way home tonight.

With Waze running in the background, I was losing the navigation instructions when the iPhone locked. However, this was with the iPhone connected to my car audio system via Bluetooth. So iPhone locked, blank screen, no instructions through the car speakers. This is why I was wondering if Waze was working at all whilst the phone was locked.

I then switched Bluetooth off and routed audio through the iPhone's internal speaker. Success, the navigation instructions could now be heard while the phone was locked.

I need to do some further investigation on the Bluetooth side of things. At the moment it's something of an inconvenience that I lose navigation instructions over Bluetooth if Waze is in the background and the iPhone locks. But maybe it's just a peculiarity of my particular car and phone installation. More playing around necessary perhaps.

When your iPhone locks Waze continues to give you navigation instructions, yes? Yes, you are still contributing drive data to Waze and earning points when Waze is running and your iPhone is locked.

Likely Waze made this change so that their application does not prevent the iPhone from locking when Waze is not in the foreground. It's not the active application so likely it shouldn't be overriding how applications operating in the foreground affect locking. I suspect there is some development standard on this. Maybe an iOS developer can elaborate.

Yes, playing music via the Music app or other applications on the iPhone which play through the car stereo via Bluetooth. Waze running simultaneously lowering the volume of the music app when announcing the next turn.
