Maps Navigation Bug / Missing Value for GPS Accuracy

**juhwie** · 06-14-2010, 11:18 PM

Google (Maps) Navigation is not working on the Spica neither the official one nor the Brut version. To me it seems that the missing "GPS Accuracy-Value" in the Spica causes this issue. When you run "GPS Test" you will get the Satellite Signal Strength and a GPS fix - but never a value for the "GPS Accuracy" (top right of the first screen / stays always 0). If Maps Navigation needs this value you will never get a GPS Fix - always "Searching GPS" on the bottom of the Navigation screen.

This seems to be a driver or kernel problem. Has anybody an idea how to overcome? Samsung is not reacting :-(
Is it possible to set a fixed value for the "GPS Accuracy". I think this major bug is somehow similar to the VOIP problem....
Thanks

I have the same problem. Navigation with iGo, Navigon, CoPilot and Sygic is fine, but Google Maps keeps searching for a signal which is good enough

Same here, nothing works on GPS. At least at home. I live at the very first floor (and I have 4 more floors above) and there's no way I can find any GPS signal. I hardly managed once with GPS Tracker, half-hanging outside the window. It's odd, because at Faculty it works almost perfect (it detects me in the room next to me), but in the middle of the street - blank ("Your location is not available at this time"). The fact is that the Faculty is one-floor only and it is located in a wide space (without any close tall buildings or blocks). I really don't know what to think of this... Let's hope it's just the FW and it's not a hardware fault.
P.S.: I live in Romania, and the signal might be weaker in some areas, but it should be pretty decent as it worked ok with an IPaq (and the auxiliary GPS adapter) some time ago.

THank's man. At last someone explained why am I experiencing strange behavoiur in such applications as Glympse or GPS Tracker. I hope it's connected with issue which you've reported.

Could anyone having source-code research experience look at it? (sircid, LeshaK?)

Can someone with kernel / debugging experience check if the idea of the missing value vor "GPS accuracy" in the Spica (see my first post) ist the reason for Google Navigation and other apps not working?

Thanks

Gps accuracy at 0 means your location is based on gps. 100 is network, 1000 is based by ip. enz.

that means that gps is working fine on our spicas?

Surely there's something wrong. Accuracy was just the wild guess. In such applications like Glympse* or Gps tracker position is not recognized although satellites are fixed. The problem exists only on Spicas.

*Glympse seems to work fine at first sight, but when you take a closer look, Gps indicator is grey and location on website is not refreshing.

i think it's inside those apps, when i do a logcat at maps and nav, there are 2 differences:

1. Maps fetches time from NTP, nav doesn't. But it might be because the phone cached it.
2. Maps feches network location once, after that he gets a gps fix. Nav request's network location multiple times, and has problems getting a fix.
