[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?

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.

A-GPS working on TP2

If anyone is interested I have got A-GPS working on my TP2, unbranded standard WWE ROM, Vodafone UK network.
The steps performed are as follows (As always, Use at own risk, make sure you have a backup etc etc...)
Install T-Backs GPS fix http://forum.xda-developers.com/attachment.php?attachmentid=188959&d=1243353858

Note you will need to change the APN, network and GPRS connection to suit your network
This fix definatly works on my phone, I have analysed the debug logs and the NMEA logs and can see the data being downloaded and injected into the driver.
I now get a cold GPS fix in less than 20 seconds, whereas with AGPS turned off I could be waiting for 5 minutes or more for a cold fix.
To see if it is working on your Phone, first you should see a GPRS data connection established then using the HTC GPS test tool to examine the NMEA data you should see a $GPCELL entry after a few seconds.
Hope this helps.
Tom

hey Tom, something you might find of interest,
I had already set up my agps as you have said above with nokis.supl and my agps was workin great, after reading your post i changed the Reg setting for Ril/driver to 1 and SR ( mine was set to 5) as you suggested. and although i was still recieveing the NMEA info, i couldn't get a lock, changed it back to 5 and Lock from cold in 15 seconds!!
I don't know what the decimal 5 instructs and possibly its radio related? i am still using stock 3.44.25.25.27
Anyway great post

Frogfoot, how does the performance with A-GPS enabled compare to the performance with it disabled? How sure are you a) that A-GPS actually is enabled, and b) that it is A-GPS that is making the difference? I ask, because I can get a lock in 10 or 15 seconds with A-GPS turned off. Simply installing the GPS patch did that for me!

I have found that I get a much faster lock when 'cold starting' the GPS, ie after the ephemeris data has expired (if you havent used the GPS for say a week) or you have changed location by say 50 miles since you last used GPS. Without aGPS a cold start would take several minutes, however with aGPS working it takes a matter of seconds. (there is no difference in a 'warm' or 'hot' start scenario).

I installed the debug tools and could see the procedure calls reading the registry entries, opening the GPRS connection downloading the data etc. And I also used the HTC GPS tool to log the NMEA stream and searched through to find the response from the supl.nokia.com server in a string marked $GPCELL

I expect that what you are seeing is what is known as a 'warm start' where the GPS chipset has cached the Almanac and ephemeris data for the last known position and uses that to jump start the connection. That is fine untill you go for a long drive/flight with the GPS off and then it assumes you at the old location or there abouts. This can cause the GPS to think that the wrong satalites are overhead and therefore take longer to lock on. The other scenario which benifits from agps is if you dont use the GPS for a while, the cached Almanac and ephemeris data expires and needs to be downloaded again. This is what causes the long TTFF (time to first fix)
Quick GPS as far as I can gather is supposed to download predicted almanac and ephemeris data for your region and inject that into the GPS driver to facilitate a faster TTFF however I have yet to notice any difference when QuickGPS is up to date as opposed to it having expired data.
Hope this clears it up a bit.
Cheers
Tom

Very interesting, do you usually connect with GSM or 3G? I have only tested this with GSM, and have not experianced the problem you describe.
Tom

For completeness sake here are two useful apps for general GPS testing
CleanGPS.cab, very useful to reset the ephemeris and almanac data and HTC GPS Test tool for diagnosing GPS fix problems

Apologies if this has newbie written all over it... What would I need to change for this to be compatible with T-mobile US service? Looking at the cab registry keys, it looks like I should be fine as is.
Thanks!

Thought I would mention what I've been using on my TP, very similar with a nice cab.
http://forum.xda-developers.com/showthread.php?t=478199&highlight=t-mobile+agps
The only thing you might wanna change is the connection settings to match the name of your data connection...

For the benefit of us newbies, could someone clarify what changes (if any) need to be made to the above registry values to get this working on O2 in the UK (if this is possible)?

Already test mine using agps setting from frogfoot, but it doesn't work on my TP2,
Frogfoot may i know what Radio version you used to enable AGPS on TP2
Thanks

I know my GRPS connection, but is there anybody know what is "APN"? How can I set it?
I found here the APN setting is empty.

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.

Serious GPS Problems I NEED HELP (UPDATE 4-12-10)FIXED

Hey guys. I know there are dozens of threads here on XDA about GPS problems. Well, I have sifted through many for weeks now, I have tried and tried tweaks, hacks, whatever and I am having no luck. I used to have my GPS working with bing, google maps, whatever. I installed TomTom and never got it to locate a GPS signal, since then I have not been able to get any GPS working that I can recall.
I am not sure if I have replaced or deleted some file during all these registry hacks and tweaks, so I am at a loss. I just want to get my GPS working. I am no noob, so please no rude remarks. I just need some help. I cannot get this thing licked for the life of me. Any and all help would be greatly appreciated. I am using an Energy Leo ROM with Sense 2.5 if that helps or matters to anyone.
Please, people, somebody help me get this GPS working again. THANKS SO MUCH IN ADVANCE.
EDIT: I fixed it, if ur curious check out post #7

Since you're "no noob" I assume you've already hard-reset your phone...?? And/or tried the Task 29? And then re-flashed to a stock rom?
If you've done all of those things (surely you have if you've been troubleshooting for weeks) and GPS still doesn't work then it seems like you must have a hardware problem.

Yeah, thanks

Since you're "no noob" I assume you've already hard-reset your phone...?? And/or tried the Task 29? And then re-flashed to a stock rom?
If you've done all of those things (surely you have if you've been troubleshooting for weeks) and GPS still doesn't work then it seems like you must have a hardware problem.

Alright, figured I would get some type of remark anyways, but it's cool. I have done a hard reset which I was trying to avoid, but I have not reflashed to a stock ROM and back again. Once again, I was trying to avoid all of that, but if there isn't any other options, it seems like that's what I am going to have to do. It's just since I flashed to the energy ROM, my GPS did work, it just stopped working suddenly. Thought there could be some connection(s) settings that got changed or possibly a file lost or changed.
I am willing to reflash the phone, by all means, but I thought I would check with my fellow hacking badasses to see if anyone could come up with an actual idea instead of telling me to change the phone BACK to it's original out of the box state, but if not whatever, guess I might have to bite the bullet.
If anyone else has any ideas, please let me know. I'm gonna hold tight on reflashing the phone for a few days to see if anyone has any other ideas.

what version of TomTom are you using?
i found with TT7 it will not show how many sats you have. and its a bit of a faf getting it to work, but i do have it working like this
in the gps settings of the phone set theprograme port to com 4and the hardware port to com5 and the baud to 4800
in TT and go to gps settings under preferences
change the GPS device to other GPS set the com to com 5 or 4 (try both)
go outside in a field etc, and wait 10 mins, you will see the latitude etc change, wal around and it will keep changing, but there will be no blue bars to tell you your signal strenght etc

It's easier to help you if you say what you've tried -- a little more detail than you're giving. Like, after you hard-reset did you reflash the Enrgy rom and try the GPS before adding Tom-Tom? If you did a hard reset, returning the phone to the basic Energy rom (without Tom-Tom) and GPS still doesn't work then Tom-Tom isn't the problem. But who knows... good luck.

In my version of TomTom (ttn7.916.9189_qvga_blue) I find my satellites to be working no problem as per the display of locks on the navigation screen. No tinkering required.
As for the GPS issues, I would guess try another radio version. When you flash a stock ROM back on, it usually replaces the radio. In Southern California I find the .77 RADIO to be excellent with GPS.
Just update Quick GPS, try the .77 radio, stand out on the street for like 2 minutes so it can get a quick lock. With .77 GPS works in my house where it never did before.
I too had a helluva time getting this GPS working tits on the Touch Pro 2 when I first got it, now it's awesome!!

Thanks I will try

I have reflashed my ROM more than once since all of this began in order to fix this problem with no avail, but I cannot say that the radio every changed since I was reflashing with an Energy ROM each time, so I will try what your saying about flashing the radio with some different ones. I am not sure what my stock radio was, so I will just have to experiment, but I will get back to you after I give this a try and let you know what happened if anything.

Got it Working Now
So I tried flashing a new radio. I also found another setting, though in the settings panel that I believe fixed this. It is as follows:
Settings\Connections\Advanced Network
When you're in this area, check the GPRS tab at the bottom. It has two options to set your GPRS to, one is PAP the other is CHAP. Mine was set to CHAP, so I changed it to PAP and VOILA!! Went outside,used Quick GPS, used the HTC GPS Tool, and it found satellites. Then I opened up google maps, bing, TomTom, and they all worked perfectly. So, if anyone else is having a similar problem, then give this a whirl. Make sure you check out different radios as well. I have now and my signal is strong inside and outside with my phone calls,internet, and GPS.
Thanks everyone for the help

Must be your local servers. I was using CHAP without GPS problems. The only difference is that CHAP uses secure authentication with the servers. I'm in LA.
BTW, are you using the "Quick GPS" application to download satellite positions? It really speeds up signal acquisition.

[Q] gps not working on tilt 2!!!

hello i bought this beautifull phone, but the ****in gps not works!!. I tried with garmin and choose GPS intermediata driver, and then of 3 hours, cant detect any satelite. Same with google maps, if i choose USE GPS. It says seeking gps. then GPS error bla bla.

have you tried updating 'quick gps' tool?
is 'my location' enabled?
is 'agps' enabled?
maybe try a different com type under gps settings?

try com 3. it is a popular port.
i havent ever tried another port. though.
so. cant speak from personal experience.

I sincerely hope you haven't got a dud. I had to have my TP2 warranty exchanged after USB sync was no longer working. The first replacement I got would not find any satellites either.
So back it went, only to be replaced with one that had a badly fitted front bezel ... so much for T-Mobile quality

hello. i tried in com 3...same not works

i did hard reset. Installed google maps, activated gps and stay "seeking gps..." for hours=(((((((((((((

I hate to be the one to point this out, but if you are using a stock ROM and it isn't working, perhaps you should think about doing a warranty repair/exchange. That would seem to be the only thing left if, as I said, you are already using a stock ROM and have done a hard reset.

Ill have to live with that. So thanks anyway.

You always have the option of a bluetooth GPS receiver.

There's a thread here: http://forum.xda-developers.com/showthread.php?t=523676 with GPS tweaks. Might be out of date though.
I'm not sure if it's in the stock rom but as previously posted make sure you run QuickGPS and download the latest sats. After that run HTC GPStool (google for the cab if it's not installed), click Open Port (mine by default is COm4, 56700 baud rate), then start test. Let it sit a few minutes in an open area (outside). Once satellite used starts increasing stop the test and run Google Maps. Should lock on quickly.
I don't know why GPSTool makes the phone lock on so much quicker, but without running that first i've never gotten a lock on my phone with google/bing.

hello i already tried with htc gps tools, a few days ago, but it couldn find any satellite in that moment.
Ill try again tomorow, thanks for help

Hmm. If you run the HTC GPSTools for several minutes (~10 minutes) does the device start to get hot? That might help indicate that the hardware is working to power GPS antenna. Just kind of a wild guess though.

This is the simplest way to test for a hardware failure. The GPS in the unit draws considerably more power while trying to locate a signal. If the device warms up noticeably within about 15 minutes or so, this will tell you whether the GPS is even activating at all.

i tried again with the gps tool, and it not works. Device is not hot, and google maps keeps seeking gps
edit: hello i was scared, and maybe i did **** on my pants, but i flashed a new rom on phone, ill try with gps again on the morning
edit2: gps still not working,
Satellite Viewed: 16 Satellite Used: 0

Well, if the device wasn't getting noticeably warmer while seeking, then the hardware is very likely at fault. I would recommend that you try to have it repaired under the warranty. If you would rather live with it, then there are plenty of Bluetooth GPS receivers out there that will work wonderfully.

As i say warranty is not an option for me. Well, i really dont need the gps for now.
And yeah i can live with this sh.. just kidding, i love my phone and always will love it
thanks for all help

I had a similar issue. I installed the Energy ROM and it fixed all my issues.

easy fix
The fix is very simple. Go to start/settings/home and turn SENSE/TOUCHFLO off. Now turn on google maps and set your phone somewhere and after it says active close google maps, turn SENSE back on and repeat the first step. For some reason on some roms the GPS will not work with SENSE 2.1 or SENSE 2.5 unless you lock sats with SENSE off forst then it with work with SENSE on.

wtf!!!! who are youu? a ****in genious
i turned off sence, then google maps, but after 1 minute i was bored. Closed it, and open the GPS Viewer that came in rom. After 1 minute it shows 1 satelite, 10 seconds later 2 sat. Ill try with google again, i think just needing the correct settings. So thanks a lot. Illpost results here, tomorow
