[Samsung i780] GPS cannot fix on any satelites

Hi,
I am new here and just bought an i780 in S'pore 4 weeks ago, running on i780DXHD1 (Radio + PDA). I have been trying to use the GPS for weeks using the bundled NavFone but it always could not fix on any satelites. In the signal strength, there is no single bar appear. I tried MapKing, it is the same. When i checked on MapKing GPS data stream, it is always empty. when i checked on the dailpad, the GPS logo is active(not crossed). When i turn off the GPS application, the GPS logo is inactive (crossed). With this, can i assume the GPS hardware is working? But why no data stream? I have tried turning on XTRA, but it is the same. Below is my configuration:
[NavFone]
Software Port GDP1:
Hardware port COM9:
baud 4800
Windows managed: yes/checked
[MapKing(trial)]
Software Port COM8:
Hardware port COM9:
baud 4800
windows managed: yes/checked
Please help.... Thanks!

co6ra,
First off, you need to stand in an open space before you activate your GPS. I uses Agis software too, and based on my experience when you use it the first time, the signal tends to get a little longer than usual. At times, it can even be over 10 minutes before I get a signal.
To assist your time to get the signal, I would advise you to use the Enhanced GPS found in your settings>system. Clicked on the enhanced gps and select Enable in the XTRA Enable. There is no need to select Auto Download (that is, Disable).
This would mean that the device will also use the base stations to assist in finding the location of your device. Of course the downside to it is you will incur GPRS charges.
Try it and see if you can get the signal.

Hi,
Thanks for your reply. For the past 4 weeks, i have been trying all sort of methods; standing at my aprtment balcony, in an open field, in a bus, windows seat, etc. all with at least 30 minutes. When i was at home, i stood at the balcony, turn on my wifi, and kept downloading the XTRA. Sometimes, i cannot see any bar at all; sometimes, i saw a lot of bars, with different PRN number, but all empty (strength 0), and kept changing, but still no fix...
help....~~

i have the same problem too until I download a software call GPSgate, there after I am uable to use my gps, I do not have the link , try seaching on the web.

I thought GPSGate is some kind of port sharing program? Both NavFone and MapKing is able to connect to the GPS unit, it just could not fix. Is it possible that the GPS is locked?
Anyhow, will try on GPSGate later. What is the recommended configuration?....
Thanks!

Installed GPSGate, and found that now MapKing is able to connect to the port and receive data. When i check on the GPS stream, it always appear to have the first line with data(some figures deliminated with ","), but follows by a few line with empty data (no figure, but a lot of ","). When i checked GPSGate, the status of the input port is always "GPS data but no position". I have tried just now in an open space, clear night sky, for at 40 mins, it still cannot fix on any satelite....
Help!...is this something to do with hardware?

I just tried gpsproxy, it still does not solve my issues.
Where did you buy your unit? I am thinking of sending back to samsung. If i am sending back, this will be the first and last samsung unit that i am using...

Since you have not flashed to any custom rom (I hope you did not) why not send your device back to the SSC and lodge a complain that the GPS is not working at all.
If they say nothing is wrong, ask them to demonstrate that the GPS is able to lock in the signals.
I know it is frustrating to have features and yet not working. It can be a case of hardware issue. Let's see how the SSC can help you, since yours is still under warranty.
I wish you would be able to solve your GPS issue. i780 is still a great phone. Let us know how it goes, okay?

ya...i am travelling now and expect the GPS to work....should have not trust it will work out from box. will visit the SSC when i am back to S'pore 3 weeks later....

In the meantime, just keep on trying, if you have time to spare. Who knows? You might have it resolved by then.
All the best... And good luck...

According to http://gpsinformation.org/dale/nmea.htm, GGA is one of the most important stream to provide location data. From the log, it seems like the GPS is not able to calculate the current location at all? What is wrong with the GPS unit???...
Ya...i have been trying to put the GPS on everytime i am outside, in total, i think i have tested no less than 10 hours, but still no luck....

co6ra,
From the looks of your log file, it seems that your GPS chipset might not be working. Those coordinates that you have should come from the base station of the phone.
I tried it indoor, and it seems that there are satellites showing, but just could not get a fix on it too (But then, I was indoor).
Your log file might be useful, especially when you bring your unit back to SSC for service.
P/S: My settings are as follows:
Enhanced GPS XTRA is enabled but Auto Download is disabled.
When running NavFone, my settings are as follows:
Don't worry about the external GPS settings, just leave it as it is.
I will feedback later when I am on the balcony. Please be patient.

Yes, what you said is true, the GGA data is the coordinates of your device and determine your location.

I have sent the same log to Agis and Samsung via emails. Waiting for their reply. Hopefully they can solve this by next week, so that i can use it when i need it most as i am travelling to Malaysia now.
BTW, do you guys think that this might be a locked GPS? Anybody has any ideas? If so, how to unlock?

Locked? what do you mean? It shouldn't be and it should work right out of the box.

i am not sure also...read few article on locked GPS topic, which they key in a code to unlock/activate the gps unit.

No luck. Samsung Singapore support does not even want to reply to my email....
Just happen that one of my colleagues travelled to my local office. Has switched back to my old BenQ P50 and let my colleague to bring down the unit back to Samsung S'pore. They claim that it might be a software issue and saying that they are going to flash the latest ROM to see if it helps.

Hi,
I notice that u r using the cooked ROM. Did you backup the original ROM before flashing the cooked ROM? If so, how do you backup?

I went through this same thing, I now have Tomtom7 running perfectly and getting a fix in seconds.
It is highly important that you have a working Sim card, correct GPRS or EDGE settings and that XTRA is Enabled!
Use GPS Gate stock settings! ie. prior to running GPS Gate goto External GPS and select com2, then run GPS Gate and use the wizard and let it find Com2.
GPRS/EDGE should try to connect automatically if not then switch it on, exit and restart GPS Gate. Be patient on the first fix it can take 5 mins, it should not take this long though.
Wait until GPS Gate shows that dark green icon in app tray and has a valid position, once it does then execute your GPS software and use (Franson Virtual com 1) default comport generated by GPS Gate.
GPRS/EDGE can be turned off after GPS Gate shows that it has your position and this need only be done once. This has worked on Omnia after many many hours of failure and frustration.

HTC pro2 GPS , help!

Hi guys
I got my first WM phone HTC pro2 recently from Vodafone UK. Everything is good except GPS. I read this forum carefully. I did hard reset, soft reset, set different port and baud, download QuickGPS, I also try some tweaks, buy GPS still not working. when I open Google Maps, clicked the use GPS, after “seeking satellite…” near ten minutes and Google Maps told me I have GPS problem. HTC GPS tool show me GPS signal was 0 and only a red spot on the top of circle. Other GPS programs such as “GPS test” and BeeLineGPS had same result like HTC GPS tool. Open Garmin, always said “searching satellite …” and Tomtom told me “Poor GPS receptions—are you inside the building?”
My questions are, based your guys experience what happened? It is hardware problem or the setting’s problem? When you guys talking about the GPS cannot get fix, do you have GPS signal on the GPS program (like signal strength, some red and green spots on the circle etc)? If I flash hard-SPL and other Radio Rom can resolve my problem? Are there other solutions? Warranty.

I used destinator 7 on a small trip, and was able to work.
However, looking at the settings screen where the signal for each satellite was displayed, I cannot say I am impressed. The signal strength was extremely low...
Can you install destinator and try also yourself?

Apologies if this is very basic, but I assume you are outside with a clear view of the sky when trying it out?

yes , i am in open field, far away from building, several times, more than 40 minutes. thanks I will try it. but I am wondering why signal strength is 0. low strength, hard to fix and no signal strength is totally diferent issue, i guess.

I am proposing the destinator, because it has a function that detects the port & some settings of the gps...

I am on Sprint in the US, but this worked for me. I am not sure if you did this.
If you have TouchFlo enabled go to the Settings Tab, then go to All Settings.
In the all settings, click the Personal then click Phone. In there click GSM/UMTS services (I am assuming you have a GSM phone, I don't know). Select Location Setting and then Get settings. Make sure it is turned on.
Then this part you said you did, but I will tell you my settings anyway. Go back to the all settings. Now go to system and then external gps. Then go to programs and select COM port 9. Under hardware it should be None and the baud rate is 4800. Then under access check the box to have manage gps enabled.
Now, when you use google maps, go to the settings in google maps and click gps settings. Change the option from let windows mobile manage my gps to manual and pick com 9 and 4800.
Then enable the gps and get a clear view of the sky and see if it works. It might take about 20 seconds for it to get some satellites the first time.

Did you notice there is a firmware update to enahnce gps fixes? Might be worth giving it a try

Thanks all.
there is not locaiton at setting, personal, phone , services.
this phone is vodafone branded, i think I need hard-SPL first to flash firmware.

Hi,
I have been experiencing the same problem. Have read many posts. It normally happens when phone your phone displays H or 3G. For some reason the triangulation and the Gps stops working.
Try it when you have E or G showing on the phone it will work like a charm.
This is my second TP2 first one never had a problem and was vodafone branded as well. Will try and find a solution and will let you know. I have tried different radios though!

Hi
I had the same issue with my T mobile branded TP2. Sometimes (after houres) I had a fix and then it dropped again. I discovered that when you switch WIFI off, it all works like charm. WIFI somehow jams the GPS receiver.

Same Issue
I have the Sprint Touch Pro2 and have tried every patch available, several registry edits, different settings and quick GPS settings to get my GPS running properly. Just before my 30 day return/refund period had almost lapsed I decided to exchange my device. Sprint tried to talk me into some drawn out process of dealing with advanced tech support and starting a ticket on the issue which would have gone way beyond my 30 day period to exchange the phone. To make a short story long, exchanging the phone couldn't have been more convenient and upon setting up Quick GPS and trying out the installed Live Search application, my phone found 9 satelites within seconds. I guess it was the device. Just a cautionary tale that if you think you've tried everything to get your GPS working, there's no harm in getting another Touch Pro2.

GPS not workign

Hello together,
i have my desire now since nearly two month. Im relly happy with the phone. But one problem:
GPS is not working, i don't get a GPS fix.
It didn't work as I had the phone completely new neither now after i rooted it. I already tried a couple of different radios but my phone doesn't find any satelites.
Does anybody else has the problem? Is this just a software bug or is the hardware damaged?
If I have to send it back to HTC, do you know how long does it take till i get my phone back? Im based in germany.
Thank you very much for your help!
best regards
Tom

I only have my desire 2 days now, it has a orange uk branded phone, so I unbranded it to a stock htc rom, and I have the same problem as you, it takes ages to lock a gps signal.
Today it took 30minutes to lock the gps signal on my ndrive.

I don't have a problem with my GPS on my Orange debranded Desire, what ROM are you debranding with?
Sent from my HTC Desire using XDA App

I use this one because of the portuguese language:
RUU_Bravo_HTC_Europe_1.15.405.1_Radio_32.30.00.28U_4.05.00.11_release_121684.exe
Do you use any program to help catch the gps signal?
Regards

I lost mine with a radio update, had to use 32.30.00.28U_405.00.11 to get GPS working again. Which radio do you have?

NDrive has problems locking with the Desire's GPS. Launch NDrive, press home button, enable the GPS and goto NDrive again. That works for me most of the times.
Or use Google Maps to get a fix and then launch NDrive.

Thanks, i will try that, as soon as I can I will report if it works.
Thanks again

I tried it with these radios:
32.30.00.28U_4.05.00.11
32.37.00.32U_4.06.00.16_2
32.41.00.32U_5.08.00.04
And with none of them I got GPS fix.
I tried it also with differnt applications:
Google Maps
Navigon
GPS Status
GPS Test
But without success, no GPS fix at all
Oh by the way, i tried it also with the Stock ROM and with OpenDesire 1.4 and OpenDesire 1.5
€: I use now OpenDesire 2.1 with the newest Radio 32.42.00.32U_5.09.00.08
I still don't have any chance to find a satelite. Has anyone an idea to fix the problem?

i don't know if it's allowed on this board, i just wanted to push my message to the first page, after it was now on page 15. Perhaps anyone has an idea about fixing the problem.
Thank you!

All that worked for me was trying the radio I had originally (before I started playing around). You tried any of the older ones?

Hi,
I also now have a problem with GPS fix. First I have overheating & reboot problem, then MB were replaced & now I can't get fix (no satellites at view at all). I hope that this is software related (although I do not use GPS much). So probably somebody knew how to perform cold reboot of GPS sensor (I perform this with previous Touch Diamond to bring GPS back to life)?

hi,try running google maps with the GPS turned on for some minutes, say about 20mins and then check if the GPS locked.I had the same problem when I updated my unrooted,unbranded and unlocked Desire on Monday.It took almost 20mins for the GPS to lock but after that,the GPS locked everytime i try to use Google Maps.I hope this idea solves your GPS issue.

I have the exact same problem. no gps signal at all. The radio is the same. Have you solved the problem?

Just be patient, very patient. The first GPS fix can take very long sometimes, even on dedicated units not just phones, has to do with clock synchronization and satellite identification. So just keep your phone out in the open with Maps startedand wait. Wait. Wait.
Once you get a fix the GPS will work much much faster.

No, with gps status you could not see any satellite after 1 hour of beeing in open sky.
Something was wrong software side.
Now with a rooted phone, same application, I get 10 satellites, and first fix after 10 minutes

You rooted the stock FroYo ROM? What HBOOT were you on?

It worked for me! I went to the roof as today is a bright day and used Tricorder app's Geo tab. Touched on it to show satellite.
It kept trying to connect to satellite. The tricorder app shows some satellites as green. Presumably as they are chosen to calculate location. It didn't finally lock-on till it was showing 12 satellites and 4 of them were green. I noticed that I had to remove the jelly cover and :
1. Stand still, she how many satellites it shows signals. In a few seconds it will stop detecting new ones.
2. It it hasn't locked on then move around a bit and change some orientation then step 2 again
3. Repeat above till it latches to atleast 4 green or 12 total signals (dont know which one works the 12 signals or 4 green)
and after that it easily updates even indoors for me.

i have the same problem and the same vers of froyo...etc . i tried with just gps ,motonav, gps test....and no change. after 20-30 min in open sky no satellite was found how can i fix this problem ? rooting is the only way ?
p.s. pascanu : daca te rog imi dai si mie id-ul tau de mess sa vorbim poate ma ajuti sa rezolv problema asta enervanta cu gps-ul ? ms

Im sending my phone to HTC

maybe changing the radio will help ?

I have the same issue, have tried a few different radios but still no satellites to be found, tried for 20 minutes with no luck.
Downgrading the radio now to test again.

Still nothing. Has anyone tried reverting to 2.1 to see if the problem still exists? Or is it a hardware failure?

try this... go to menu, settings wireless, network, then go to mobile networks, access point names, click on your service provider( the one with the green button by the side of it), like mine is o2 postpay then go right down to the bottom & open APN type, then type in default,supl

Thanks. I have exhausted everything now and it still hasn't found a single sat. Back to HTC with another hardware failure...
Has anyone else with GPS problems solved them?

I got mine back fully functional after 2 weeks with HTC.
All Free of Charge.
Great service.

Well, do ya know what they did to fix it? Would be nice for the rest of us to know I'm having issues on my Desire with the newest Froyo OTA update and radio 2.29.405.8...

Solved it just how the person said above, after the update that APN doesn't download the Satellite lists by default, you have to add that line to get quick GPS locks.

I've tried adding supl but I still can't get a fix. I'm on tmobile uk, stock rom if that's of use to anyone.

Differences in GPS accuracy in radio versions?

Hi,
I'm currently on radio version Radio_12.35d.60.140fU_26.08.03.07_M_Test running CoreDroid Desire HD V4.6.
As I'm using my phone for Geocaching, I'm not very happy with the GPS accuracy.
My /system/etc/gps.conf is set to NTP_SERVER=europe.pool.ntp.org.
I've tried the usual reset and download A-GPS using GPS Status, and I get a fix pretty quick.
When I go Geocaching my friend with an iPhone4 (!) has a much more accurate GPS. I miss my target with 10 m.
So my question is, are there any differences in the GPS accuracy in the different Radio versions?
BR,
C

I think the only way to answer this question is to suggest that you try different radios and see what works best for you.
The success or failure of the radio depends on so many factors.... where you live, carrier, rom, signal strengths, etc, etc..... and also on what you are looking for from the radio ie battery life, phone signal, gps signal, etc.
There is no definitive answer!

Some days ago I struggled with some GPS troubles too.
It took me quite a while to figure this out but it is well reproducible on my DHD (everything performed outside, for sure):
GPS from the radio 12.28e.60.140f_26.04.02.17_M2 from WWE 1.72 or the 12.35d.60.140fU_26.08.03.07_M_Test radio behave like this: When you start GPS status for the first time after boot the DHD starts to fix one satellite after another and then keep them ALL fixed. When you now quit GPS Status and restart it the DHD starts to fix satellites again but then lose some of them just to fix them again a second later or so, then loses some of them again and so on. Sometimes you then have just 3 or 4 satellites fixed. The only way for me to get rid of this strange behavior is to make a cold restart then GPS status is fine again for the first start, but after restarting GPS Status same again.
When I use the radio from the 1.32 WWE this does not appear after restarting GPS Status, it always fixes as much satellites as possible and KEEP them CONSTANTLY fixed (here in Austria regularly around 9). When I use my DHD for car nav I don’t care too much about it but I guess this might play a rule when you use it for geocaching (and need more accuracy, which is provided by more fixed satellites, if I am not wrong) … hope that helps a little bit.

This is the Desire HD's only flaw, the GPS. Well for me anyway.
You can get it working to a point. And i think all the guys cooking ROMs have got this right now.
For example i am running CM7 RC4 and i can now always get a lock but it bounces a lot. What i mean is, take google maps for example, the GPS locks, and almost never loses the lock now, but the circle that fixes your position on the map is constantly on you then way off you all the time. So it knows that you are 'somewhere there'. which for a GPS in an urban area 'somewhere there', anything from 10m - 500m, is not good enough.
In reality it is not very good at all and is very disappoint as the big screen makes using maps a big plus
I have given up on trying to get this to work now. My Desire contract is up for renewal soon so i will get another phone and at this point an HTC phone may not be my next phone. HTC has mostly great build quality but they don't seem to care if the phone features work or not. Which is sad because if they addresses this issure, and its been the same for a good while now, they would be the the best phone for sure.
Personally i think that they could do better with the camera and GPS, the hardware.
Oh and i have also tried many different radios.
