just joined the community couple of days ago and I'm quite amazed by the quality of routing and avoiding traffic jams.
However, on my Android 4.2.2 device ("Archos 40 Titanium"), sound volume trough the built-in speakers is so low that I can hardly understand the piloting messages even at moderate speeds (meaning with low noise level in the car ...). While driving on motorways (~ 120-130 km/h), it's almost impossible to hear WAZE at all. And my car (VW Touran) is definitely not a very noisy one ...
Oh, by the way, volume settings for the phone speaker are to max, as well in the phones general settings as in WAZE. And YES, I have pressed the volume button to increase up to maximum whenever WAZE is outputting a piloting message.
Other phone sounds played through the built-in speaker are much louder than WAZE and clearly audible, so the problem source does not seem to be caused by the individual sound characteristics of my smartphone.
Further I've already tried a couple of volume boosting apps from Android Market, but non of them can provide sufficient volume enhancement (in fact, the effect of most of these apps is zero (no wonder, because tech info sources in Google Market say that since Android 4.2.0 a patching gap that allowed boosting has been closed due to EU legal requirements), only very few can give at least some little volume enhancement, but still far away from being sufficient).
Switching to bluetooth output might only become an option if WAZE would provide settings and technologies to send piloting messages to the car radio through HFP and if transmission to the car radio would be started and ended automatically (i.e. without having to "pick up a phone call" and/or manually end it).
A2Dp bluetooth output, however, is NOT an option because the car's built-in radio needs to be used (at just background volume level) for other info purposes.
Could anybody please provide info how to boost the app volume on the built-in phone speakers to a reasonable level? And the needed solution must not require to root the phone because I don't want to lose warranty. If there should not be any solution, I am afraid that in this state the WAZE app would practically be unusable ... what should I do with a car navigation app of which I can not hear the piloting messages ...
Many thanks in advance for your contribution and best regards
