GPS settings / connection problems

Hi,
Could anyone please explain the various settings for GPS in the "settings" menu (under "location")? I find that the manual and tooltips are not very informative.
Particularly, I don't understand the difference between the first choice ("wireless networks"?) and the third choice ("assisted GPS"). I understand that the phone may use wifi or mobile network to detect my position (instead of or in addition to GPS satelites), but I don't know which of the two options to choose for this.
Also: When I enable "wireless networks", what does the warning that pops up mean? It mentions that data will be collected even when no software (GPS/map) is running. What is that? And what is the difference between enabling this and the fourth option ("share with google")?
Finally:
Does your GPS immediately start working when you enable it? Myself, I need to enable/disable GPS using the desktop widget and the various GPS settings several times before it managess to find my location. (My position is not the problem - once detected/connected, it works fine.) I still don't understand which combination of settings it is that finally makes the GPS work as expected.

As I understand the first option "Wireless Neworks" will rely entirely on data from Cell Towers e.t.c to determine your position. I guess this will be less accurate.
"Assisted GPS" enables your device to get a faster lock on your location by collecting available data from cell towers first before using the GPS receiver.
I think if you were only to activate the GPS in some circumstances it would take a lot longer to get a fix.
"Share with Google" just allows the gears addon within the browser to share your position with google allowing them to return results based on your location.
That's my take on those options.

"Wireless Neworks" - is using cell towers and wifi to locate you.
Probably they have (or use a 3rd party DB) for that. Anyway, is not (very) accurate.
"Assisted GPS" - i'm not 100% sure but i think is connecting to a location server to get the location of the GPS satellite so, will lock faster (at least this is what my Nokia 5800xm is doing).
The warning message you get is because google will (most likely) use your location (cell towers and wifi spots) to create and update their own database so, phones without GPS will still be able to use google maps.
Well, they probably do something more with that data but who knows what

I just wanna add that using any type of assistance for the gps chip in this phone is (in my personal oppinion) unnecessary. I am sitting inside my house, in my bed(with a window behind me) an in 10sec i get fixed on 10 satellites. Not much that can beat that ;-)
in addition, i am in the bottom floor in a 2floor house so it is alot of roof and cealing between me and the sky.

Thanks for your replies. Much appreciated.
Just curious - which app do you use to monitor GPS satelites?
Also, does everyone's GPS find your location rather quickly after enabling GPS? I usually get the message "Your current position is temporarily unavailable", I retry, same result, I retry, same result ... Only after I disable/enable GPS several times, my position can be found.

My GPS usually finds my position rather quickly first time I switch on GPS. I have aGPS (Assisted GPS) enabled too, this way your phone gets help on locating the sattelites position from your mobile provider, hence locking onto GPS signal faster (is to my understanding).
Plus, if you're standing in an area with tall buildings, your position will be less accuratelly pin-pointed, bouncing GPS signal and all.

I'm using GPS test by chartcross ltd. Avalible in the free android market, and i really like it!

I never turned on A-GPS on this phone. There is no need for A-GPS.
This phone have fastest GPS fix of all phones.

I have noticed when I am running on 3G (H) I get the "location temporarily unavailable" notice, but if I force it to not go to 3G it will be E and I get my location. This holds true if I have setting for using GPS or not.
This seems to be a problem with Google Maps using the data transfer method of 3G (H) versus E.

Best JI6 GPS settings

I hate to start another thread about GPS, but I was seeing many people over in the dev forum getting very accurate readings from the GPS after applying JI6.
I was wondering what the best settings are to optimize GPS accuracy after the JI6 update?
www.spirent-lcs.com and port 7275 or supl.google.com and port 7276?
Keep accuracy at 50? What about skyhook? keep it off?
thanks in advance

Most of them just leave the original settings, and so have I. Getting exact reading while using my tracks from google.

I just updated to JI6 and i don't know why but it still thinks I'm somewhere far off...not nearby...about the same as before...
How do you change ANY of these things you guys are talking about?
I'm new to android (from ios)

These are settings you put in LBSTestMode menu, which you can access by dialing *#*#1472365#*#*
You should let your GPS catch before actually deciding if your GPS works or not, mine started crappy but ended up flawless, if you decide that your GPS is crap then you might go change the settings.

you guys are getting accurate locks with the "use wireless networks" option checked or unchecked?
i don't get any satellite locks at all when I only check "use GPS satellites"! I have to check "use wireless networks" for my gps to find me
I just got the JI6 update via Kies Mini

I get accurate results with it checked, and for which it is 100% of the time when I use my phone too.
I did uncheck it just to test it out and stepping outside, it gave me an accurate location and fast too.
My phone of course has the JI6 update, if it needed to be said.

Actually, the dialer code you used no longer works after JI6. It is now
*#3214789650# to get into the LBSTestMode menu.

Maybe I have to step outside too. I'll test it out tomorrow on my way to work.

Minor correction. The correct lbltest mode code for the newer JIX builds (including JI6) is *#3214789650#
I've had mixed results with GPS since upgrading to the newer JI6 firmware. Some days it seems like I can aquire a GPS signal within thirty seconds or so of turning GPS on. Other days it takes upwards of five minutes. I have more or less chalked this problem up to signal quality in the areas I am turning the service on in. Since I work outside of the states the problem could also be due to wherever the phone is pulling SUPL data from as well. I'd be curious as to what other expatriot users have their phones set to utilize for SUPL data. At the moment I am running the phone in cold boot/MS Based, as this seems to speed up the time it takes me to nab a decent signal.

I have the same questions and more....
I thought a cold boot/start would start your GPS as if it had no memory of where you where last, I mean in what part of the world. My handhelds and a CF card GPS would cold start from the city they were manufactured in, then slowly find their way to N. America locating birds and then slowly zeroing in on my location.
Hot start would put me at least in my home state to start then locate the birds that are in a geosynchronous orbit (the sats/birds that are always (mostly) over head, they turn as the earth turns) Since the birds are always overhead of this general continent and I too tend to stay in this general continent. After first uses I keep it on "hot" start so the GPS chip doesn't ry to find me in Asia first.~
Now the above statement are base on some assumptions: Is this indeed what hot and cold start means on this device? (it does on others) Also when does it go to a colds start? During reboot of the device? Do the settings Cold and hot always force these types of starts? How long is hot start memory stored on the device?
I'm not even sure flashing new firmware or a new GPS version resets the settings to default. Some have reported instant locks some complain it takes a while for first locate (normal).
Two major questions now that we have the correct codes to adjust them: what are the defaults and did the Ji6 flashed upgrade reset them to default? Did it make a difference via ODIN, OTA or mini Kies?
I ask this because my GPS worked great with the leaked Fix flashed, now after the Ji6 update it works like stock out of the box (crappy).
So as the first question on the thread asked what are the best settings for the new update? And if stock is it what is stock? Did the update revert the settings back to stock?

Ji6 settings are standalone, hot start, GPS plus on, dynamic on, accuracy 50. Sky hook off, PC off

GPS/location issues?

Hi folks,
I encountered problems with the location service of the Omnia7.
At first, A-GPS is working very rarely -most of the time I don't get a location until the real GPS finds a signal (that means I get no location indoors).
Second, the GPS doesn't find the right location. In 9 out of 10 tries, the GPS thinks I am somewhere in the Czech Republic (which is about 600km away). This bug occurs in Bing Maps as well as in WeatherBug.
Very rarely I get the right location but most of the times it's completely off -but it's always the same "off", so I think there must be something wrong with the GPS module or the software.
So I can't use the phone to navigate or as a sports tracker.
I wrote the Samsung Support today, hope they have an answer.
I hope for you guys to confirm or deny this issues.

Used bing maps few times already and never got a problem with them.
My wifes omnia is getting fix in about 2minutes still or even 10 when I am on the move.
Omnia on the other hand is getting my location very quickly (I have location turned on). Last time on halloween noght we were lost at some suburban area and my phone get us from there very accurately. I could see us moving like on proper sat nav application. I know we have to wait a little bit for nice TomTom or iGo.
Second hard situation, I got my location today at work (under roof) where HTC HD was getting signal only standing close to window. It is ok for now if u ask me.

No Problems Here...
Hi there,
I am getting "room level" accuracy all the time. If I am at home in the bedroom, Bing maps on maximum zoom in shows me in the bedroom. If I am on the other side of the house in the living room, it shows me in the living room.
Seems perfect to me.
Cheers,
Pete

Thanks for your replies...
...the strange thing is, it seems to be working now (for 1 day it's fine). I have played around with the Diagnostics menu (GPS-settings) and since that it's okay as expected. Maybe it's just a coincidence, but I hope it's staying like this.

I also have problems with my Omnia 7 : the map is very imprecise (the gps apps indicate a 3000m precision) so I think it doesn't manage to get a fix and use 3G triangulation instead. I tried waiting for about 30 minutes outside, but nothing changed. The weird part is that it started working at same point, for a few days, and then broke again. I have no clue about what's happening.
I'm pretty sure I had those problems before discovering the diagnosis menu, but in case I tweaked something I shouldn't have, can someone (with a working gps) give me his settings ?
The "Test Mode" menu can be called by dialing *#1575# in the diagnosis app. Then there's three options in the "Change state" menu.
Thanks in advance.

I was having the same issue. My settings were off as well. My device was set to UP MOLR state vice CP MOLR state. How does that happen? When I was on NoDo, the GPS was working great.

Location services don't work?

I remember why I sold my original Optimus 7 now, I bought a new one yesterday as it was on offer, but for the life of me I can't get location services to work, my iPhone instantly find me, this phone just sits searching and gives and error it can't find me. It seems to be using GPS which when in doors isn't going to find me, it doesn't seem to use WiFi or Cell Towers. Outside its hit and miss if it finds me. I'd say it was a dodgy phone if the original phone I had didn't have the same problems.
Anyone any ideas? Its not that the location is off a bit, it just simply can't find me via wifi or cell

Vodafone's Optimus 7 firmware is broken - I worked out this works:
In MFG, navigate to Engineer Menu / Device Test / Sensor Test / GPS Test / GPS Setting
In User Setting, use following values:
Operation Mode: MS-Based
Accuracy: 100
Aiding Data: Hot Start
Auto Answer: Disable
Interval: 1
Number of Fixes: 9999999
Intermediate Data: On
In System Setting:
URL: supl.google.com:7276
Posnode: 255
2G: Loc Estimate
3G: Loc Estimate
Use Security: Use Security
MO Method: User Plane
PLEASE sign up on the Vodafone e-forum to add your voice to the request to get this fixed on this thread:

Thanks for this, Going to flash a generic European ROM and see what happens

Not working for me.
LG E900 Vodafone

I flashed the unbranded European ROM and they still don't work. I am thinking it a bug with all E900 phones.

Tried Nokia maps and it found me instantly in the house, The Weather Channel also found me instantly, so I think it all comes down to the app.

Focus 1.3 GPS Knowledge Dump

Got bad Focus 1.3 GPS performance? Info below helped me. Not for the fainthearted, requires unlocking and registry edits, YMMV, I'm not responsible if you wreck your phone, I pulled some of this info from other posts, etc.
Symptoms:
GPS accuracy/ability to lock degrades. Updates & reflashes make GPS work great for a week or so, then it has trouble locking, then stops locking inside 350 meters at all.
Fixes:
These helped; not sure all are needed.
•Change settings
-WiFi: on (improves initial H accuracy)
-Location: on (obviously)
-Cellular: on (need for initial fix)
-Find my phone: connect and save both checked
•Diagnosis App
Enter "Test Mode" by dialing *#1575# in diagnosis app, then see three options in the "Change state" menu:
-MOLR CP/UP: Set to CP MOLR state
-3G MOLR request type: Set to LocEstimate type
-TLS Option: Set to Tls on
•Registry tweaks (must be fully unlocked, use WP7 Root Tools for reg edits)
-HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\GPSOneDevice\OpenStandalone
Change from 0 to 1
-HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers\GPSOneDevice\QOSAccuracyMeter
Set to 100
•Reset GPS when it stops getting a lock
1-Remove battery
2-Remove sim card
3-Let phone sit with battery out for 10~30 minutes
4-Replace battery and restart without sim card
5-Shut down and replace sim card
6-Run and calibrate compass app before launching GPS app
•Use offline apps
At first I figured my problems came from lousy Samsung satellite GPS hardware. Then I read this on a MS dev site:
-"GeoPositionAccuracy.Default accuracy uses Wi-Fi or the Cell tower signal ..."
-"GeoPositionAccuracy.High accuracy uses the [satellite] GPS receiver ... built into the windows phone device."
-"Developers write apps to use GeoPositionAccuracy.High accuracy instead of GeoPositionAccuracy.Default ONLY WHEN NECESSARY, because it could ... affect the performance ... So, devs use Default accuracy level whenever possible."
So I started wondering if the phone would be more accurate with all data turned off.
Result: works much better with data off. Using MapSnap GPS with no data, there's no more location jumping between cell towers, just a steady track. Tracks me hour after hour on bike rides, hiking under trees, etc. Tracks exported to Google Earth are pretty accurate. Best thing is I can use the GPS offline week after week and it keeps locking down to ~10 meters.
Tip: Get your first fix with data on before going offline. I open MapSnap, get initial fix, then go into airplane mode.
Apps: MapSnap GPS is flawless, but you need to supply and calibrate your own maps. Haven't tested with Nokia Drive because I don't need turn-by-turn, but people say Drive works with no data.
EDIT: Just tested with Nokia Drive and works well with no data. Same drill: get GPS fix in Nokia Drive with data on, leave app running in background, turn on airplane mode, return to app.
Best Guesses for Focus 1.3 GPS Weirdness:
-Driver that juggles cell tower and satellite GPS info is poorly written.
-Cell tower location driver is poorly written.

Thanks for sharing, looks like good info.
