Two weeks now with Bringgo running on my Galaxy S3. Generally pleased, but there are a few glitches. The biggest one is that there's a problem running both Bringgo and any music/audio app (i.e. Audible or Pandora) through bluetooth. When Bringgo is running, the audio from another app will drop out occasionally for a second or two (but it's not a skip, because it comes back on at the same exact point where it dropped out.) Not sure if the issue is with the phone not having enough 'horsepower' when Bringgo is running along with another app, so it's sharing CPU power back and forth causing the audio app drop outs, or if the bluetooth bandwidth isn't sufficient to always push the Bringgo maps and audio through to mylink simulataneously, causing the audio drop out.
The situation does improve somewhat if I zoom out, which probably means that Bringgo isn't pushing maps through to Mylink as frequently as when zoomed in close. If I stop Bringgo altogether, there are do drop outs on audio apps through Mylink.
Not sure if this is happening to any other Android users, but it is irritating. Likely not happening to iPhone users, because iPhones connect Bringgo over USB rather than bluetooth. (USB connection is not an option for Android, from what I read, although I haven't tried it yet.)
