[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.

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.

Intermittent GPS Problem

Hi there.
I've searched for this problem and hadn't found much information, maybe some of you had this problem.
The problem is: The GPS software don't receive signal from the GPS receiver, sometimes 1 (to a max of 3 bars) on the satelitte options of the GPS software go up, but no fix. Other times with no apparent reason it works correctly until it goes out again (from some minutes to some days).
I've tried with this softwares, and the same results:
Tom Tom navigator 7
Garmin XT
Ndrive (don't know the version)
and
NoniGPSPlot (it's not a navitation software but should work to test)
I've tried several ROMs, same results.
I've tried to clean the internal antenna contacts and bend them in a way to make a best contact.
Any guess?
Best Regards.

Have you tried updating the quickgps to get a better fix?
Also where are you running the gps from? (home, outside etc.)

Hi, thanks for your reply.
I've tried that, but I think it wouldn't make wonders anyway. One of the times I was able to put it working, was after updating QuickGPS, but now I see it was a coincidence.
I make most of the tries at a balcony I have in my apartment where I can see about 70% of the sky (it already worked there before).
Any more guesses?
Best Regards.

Depending on the location, i have realised you have to move around to get a good fix.
If you move around, say around 2 square meter in you balcony you wont be able to get a precise fix as the satellite will think your are still in the same place. Try walking around with it on the road and see if you get any improvements.
if you still have no luck and since you have tried various roms i would suggest you send it for repair?

I thought that it would be better to be still to get a better fix... It seems I'm wrong.
I'm now trying the original ROM from HTC.
BTW, "as the satellite will think your are still in the same place", I thought the GPS system only receives information from the satellites, am I wrong?
Best Regards.

Sorry i meant the gps reciever

Finally I solved the problem.
Sent my Artemis to service
The main board was replaced, now it works as a charm.
Best Regards.

GPS slow getting a fix

I have noticed occasionally my HTC TP2 is very slow getting a GPS fix using the built in receiver (up to 25 minutes to get a fix whereas normally it is under 1 minute). This can happen at the same location as previous days or hours use in open sky area. Running the built in program QuickGPS successfully has not helped. It seems as if any current built in GPS almanac is not working?
Any idea what key data files if any are needed to enable a fast GPS fix? Maybe they are being deleted by memory cleaners? What could be my problem? I get this problem once or twice a week and use the GPS daily.

Have the same problem here but not all the time.

You may want to check that warranty information. Dead TP2 GPS units *do* exist -- I had mine replaced after the GPS simply stopped working after 4 days. If a hard reset + GPS provisioning CAB doesn't work - your device has issues. I did not need QPST on either of our TWO Touch Pro 2's in our household here.

My TP2 is branded Orange. They manage the warranty. I did 2 hard reset to be sure that is not the result of a bad tweak. No result. The only one problem is low signal received. If you are in a kind of desert, the fix works after few minutes but it's not a standard usage. Friday in my car, during 1 hour, no fix. I start the Gsat receiver 5000km of the last usage (Montreal), it works after 1 minutes! I don't expect this result but I expect the same quality of my kaiser (just correct).
What do you mean by "GPS provisioning CAB" it exists cab?
I can't upgrade the radio (see my signature) because the HSPL fashing is risk for warranty of the device
Thanks

There is very minimal risk to warranty of using HSPL as you can flash the original SPL back if you need to return the device.
Try using the HTCGps tool to Warm up the GPS first.
I have issues with mine if I am travelling and attempt to get a fix from cold, if I obtain the fix before moving, it's fairly quick, max 1 min from cold, and never an issue. if I attempt to get a fix whilst moving it takes forever.
ps, GPS is NOT as good as Kaiser was
Cheers,
Beasty

Yes maybe not better as Kaiser but look the two screens on my previous post (the first from me)! You can see the result for outdoor and not in so bad condition... With only two sats at 30%, the TP2 will never fix.
If I need a desert area to fix GPS I prefer use the GSAT module. It's easier to use!

Yes, I think too! The problem, is that I get my TP2 with a small contract. They manage it as free contract. I need to send the phone order before (by mail, not by fax or email). I think, this return will not easy.
Today I will check the antenna plans, just under the back cover, with chance, one is not correctly connected...

Are you sure that the level signal was very low on your device before reflash radio?
Which radio have you now?
The Problem if I flash is the waranty and return back to the original radio If the problem is HW. I don't have the original orange radio ROM.

Hmmm. GPS Provisioning CAB seems to be CDMA specific when I look at it -- http://forum.ppcgeeks.com/showthread.php?t=78592. May or may not be helpful for you there.
My Touch Pro 2 got into a funk after 4 days of use and no matter what I'd do to it - hard resets, advanced config, QPST settings I could never bring it back to working. Now, if you're on Orange, then I believe you're using one of the European GSM flavours of the TP2 -- one that has an 'official' ROM update from HTC on their site -- before going back to warranty, reflash that phone to see if it resets the radio firmware.
I have also seen things like this with my HTC Touch (Vogue) when I was running NFSFAN's ROM on it. The GPS died, and the fix was simply to reflash the 'official' ROM on it --- TWICE --- before going back to the NFSFAN ROM. HTC devices do weird things sometimes.

I have branded Orange TP2 with custom ROM. I didn't found this ROM. I dumped mine but I don't know how to rebuild it. I cannot reflash with the standard HTC because it's not the same.
For the cab I don't know if it can be dangerous for the phone.

GPS Patch !

first we are sad that a cople of users are against us!
For this reason we are stopping with the project.
we want to help the communitie but some people dont want to help to this and want to block this kind of users.

What is the fix for?

What problem is this patch supposed to address? Slow/intermittent GPS lock, Lag, or some other problem?
As far as I can see it is simply an animated GIF set to display during boot and changing some registry entries relating to the GPS intermediate driver and increasing the file system cache.

yes tom,
the reason i added the gps is that the stupid microsoft visual studio wont allow to build cab files with out a file in it.

Do you know if T-Mobile TP2s need the new radio driver, or is the included radio up-to-date?

if yours works out of the box, don't patch it.
mine is Tmo TP2 and get almost instant sat lock, so I am not going to patch mine for now.

That's the radio version I have. What does the cab file do? Does it automatically change the registry settings for the GPS Intermediate driver? If so, I have made those changes and I still get GPS lag.

gps lag
i work at a auto repair shop and on occasion i get the oppurtunity to drive a customers car that has a dedicated gps. what i have noticed is that the lag time with those dedicated units and my old touch diamond and touch pro is that the lag time is about the same. i have not tested it with my current phone (tp2)just yet but it seems about the same maybe a little faster. imho i think it has something to do with the lag time with the gps signal having to travel so far. if we think about it, the signal has to travel out into space and then back down. things no matter how fast are not instantaneous.
btw i love this phone. i just typed all this on my tp2! great keyboard.
just my two cents

GPS is another reason I miss my HTC Dream. It was fast and worked indoors. SO far, I see no improvement with this radio and .cab. Of course, I already had an alleged GPS fix with a different radio (3.44.25.27 +A-GPS hot fix). I will test outside now. So far nothing indoors. update: well... it does seem to pick up faster outside now. good fix! not great but a bit better than before. good find!

This Fix works great in my TP2...
Question: Installed but my free program down 6MB..? BTW I'm using Miri V 1.1 Manila 2.5
Edit: My Garmin 5.00.20w works better than my TyTNII... It locks inside my house within 5 second.. More amazing in my bed room which I never get any GPS signal... Antonius .. Genius...

Sadly, mine's not working un-patched. TeleNav and Google Maps both are having a hard time getting satelite locks, indoors and out, moving and stationary

[Q] Another mysterious GPS thread

Yes, yes, I totally should have done the search which I obviously totally didn't, otherwise I totally would have found the solution. Please spare me these kinds of answers, I did my research as much as I could...
Now, the outline of the problem:
-I cannot get a gps fix. I think I probably managed get an accurate location with google maps. Once for 10 seconds, and then it was gone.
-The phone cannot see satellites.
-Antenna, GPS antenna and antenna cover have been replaced, it was repaired 3 times with the same no-lock issue. It did not fix it, tho.
-I tried stock roms, cooked roms, different kernels and different radios. It still could not see a single satellite.
-I tried the "wipe this-install fasterfix-gps-status-enable that" stuff I stumbled upon so far.
-The most accurate position I can get is around 600-1500 meters. No change if I enable the GPS satellites.
-I tried Ndrive, IGo and Google maps, under open sky for long minutes. Nothing.
Any ideas?

lol it sounds me (i had a lot of problems with my gps...)
1- u tried flashing the recommended base band radio?
2-u tried (IMPORTANT) to flash the correct RIL?
3-u tried to warm up the metalic contacts that are under the gps cover?
4-try it and then use GPS STATUS to fix it....
5-post the results please

1- u tried flashing the recommended base band radio?
Yes.
2-u tried (IMPORTANT) to flash the correct RIL?
AFAIK I need it only if I don't use recommended radio. I used recommended radios with sense roms, as well as I do now with MDJ's UD 1.8+kernel+recommended radio.
3-u tried to warm up the metalic contacts that are under the gps cover?
The phone is on the sun when I'm leaving it out to get a fix. Also, I hold it in hand, which supposedly warms it up.
4-try it and then use GPS STATUS to fix it....
See above.
5-post the results please
Still :/ http://db.tt/qH2YCbW

i´m not fully understand your post but raising a bit the contacts i was obtained better gps fix (weird but true)....
in adition... i think you should try ALL THE POSSIBILITIES... in a few words... flash the RIL

HTC policy is to replace the handset after 3 repairs. Send it back. That's HTC UK anyway.

Hi to all.
Erm.. what do you mean by warm up the metalic contact?

Woah, it would be awesome. I had it reapaired in Carrefour, France. So I don't know if it stands for those repairs too. Now I'm home in Hungary, so we'll see. I will definitely keep returning it if it takes that to get a working phone...

Same problem here, except my GPS worked perfectly fine until I upgraded to Android 2.3 last week. Since then I can't get a single satellite to lock.
I've used GPS Status to reset and download A-GPS data to no avail.
HTC told me to factory reset my phone which I've done. Nothing works!!
Tried with and without SIM. Various combinations of WIFI on/off with SIM inserted and removed.
I'm really angry.
Any ideas?
Thanks
Matt

Have you been SFR? Just asking, my phone was SFR, and I read something in french about some messed up stuff of SFR software... it was long ago tho.
