[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.

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.

Are there definate settings for TomTom7 without Phone being on?

Hi all,
I have been searching this morning and found some possible solutions (most notably this thread) however I still cannot get a GPS Fix in TomTom 7 with the Phone Off - I get the "All connections disabled" message.
Reason for no phone is I am giong to America on holiday tomorrow and therefore will not be using the phone due to the charges etc.
Are there any definite fixes for this yet? I used the same reg settings (minus the IP and port ofc) from post #3 in the above thread but it still did not work. I also tried GPSMode = 1 with no luck.
I am on a VF ROM - could this be the problem?
MAny thanks,
DW

Just turn on bluetooth alone....should work....

Bluetooth On, Phone Off, Flight Mode Off - Still All Conn. disabled message
Thanks

indeed......you are right.....used to work on previous devices....
Sorry I couldn´t be of any help....

No problem, thank you still for your suggestion

Add a PIN to your SIM.
Switch phone on but don't enter your PIN. This disables the phone, but enables GPS.
Don't know about power drain though. Never measured this...

Don't pick up any phone calls, send any text messages, or use any data and you won't get charged.

Strange I have just tried mine in plane mode and google maps still uses gps picking up 10 sats, but TT7 cannot receive anything, so the receiver is still working, just a case of making it work.
Like you on my Tytn2 I used to switch the phone off whilst using tt abroad, fortunately I now have integral sat nav in the car, so no longer rely on the phone for sat nav.

Help Needed with X1 Garmin Applications

long time reader...1st time poster!!
Hey Gang,
I'm from India & bought x1 2 weeks back. Installed Garmin xt on x1.. tried using it..thought it shows everything POI, every time I click GO TO a particular place... it always come with "AWAITING BETTER GPS ACCURACY".
Do anyone know, If it can be resolved!!!
Thanks IN advance!
Sachin Ghai

click on the signal bars at the top left corner of the main page, then GPS info. Do you see your coordinates or do you see "acquiring satellites"? I only get the "awaiting better gps accuracy" when theres no satellite lock.

look at sky if ther are clouds it makes GPS hard to work.
but my X1's GPS works great and fast
but my GARMIN has 1 mistake
when I'm riding to my car and car shovs speed about 80km/h Garmin shows me about 60km/h
but on the map all streets and cordinates are very corect

Hi there,
There are still several issues in GarminXT on a windows phone! I always used garmin before i tryed tomtom and several others. at first i didn't like tomtom, but it doesn't have any problem with anything! it's alot faster and more reliable! I think you must try tomtom version 7.916. this is the latest

Hey there. I have Garmine xt too, and it didn't came with California, Oregon or other big states are missing... is this normal? i bought used one from this owner and doesn't come with the states that i travel most!! i was like wtf... even California was not in there. If this is what Garmin Xt offers, i'm changing it to tomtom or other gps systesm for my x1!! hmmp!

You install it? Or you pay for it?
To be able to "see" satelites from this app, you must register it

I'm using Garmin in my X1 for quite long time without problems.

This is not normal with Garmin. The map is just not complete. you can use Garmin City Navigator to update the maps. Other option is to look for a map for North America witch is activated already.
Good luck with it!!!!!!

You may use and SEX1_HTC_GPS_tooll too.

I am not shure if is it allowed on this forum to talk about warez...?
Anyway, you have to find keygen with instructions (it is tricky to do it but can be done).
Untill you got registered version of Garmin app with map on your device you will not "see" satellites. Also, when you all done with registration and all that, go outside and do some "where to" route and wait to find satellites for first time...it takes for minute or two (with QuickGPS installed and updated).

WM6.5 and GPS

Hi, I just upgrade my touchpro2 to wm6.5 and found the google map cannot use GPS, it can connect to GPS but said cannot find any GPS signal. Anyone have same experience? even I install other map program and the GPS didn't work......

Hi
I had the same thing. You can leave it outside in clear daylight for about 15 min as this is sometimes how long it takes to pick up the GPS after a ROM change. Also ensure that you have done the QuickGPS download beforehand.
In my case my phone was faulty from the start but after they replaced it it still took a while before it picked up the first time.

You could try HTC GPS Tool (attached). First, make sure there's nothing blocking your view from the sky; it's best to be outdoors. When you open it up, on the top-left there's a button "Open Port." Press that. Then press Menu > Satellite. This will now show you satellites near you (red). When they turn white (it might take a while), you know you are attracting a satellite. Now, without closing HTC GPS Tool, open Google Maps and hit Menu > Use GPS. It should now get your location.

I had the same issue after recently upgrading my 'stock' T-Mobile (US) TP2 to WM6.5. For me, this was resolved after a radio update. Am currently using 4.49.25.57.

check out the aGPS cab in my signature,really speeds up the lock time dramaticly, highly recommended.

Thanks for all your help! Thankyou!

Did you come right?

it seems get better but it need some more time to test!

I have a TP2 (unlocked European version, WM 6.5) and I have no problems getting a GPS signal. I always use the Quick GPS application before powering up my GPS software but when that's done I have GPS signal lock and location lock within 2-4 seconds, whether I'm using CoPilot Live 7 or Google Maps. I've also tried Navigon MN7, same thingm very fast GPS signal lock and location lock.
However, if I don't use Quick GPS it can take several minutes before I get location lock although it will find GPS signal.
All this is tested several times sitting in a moving car in both clear weather and cloudy weather. Also tested from within my apartment, although near a window.

Thanks for your suggestion but I already use quickGPS and still found the problem.

I flashed a new ROM today and the ROM only came with QuickGPS. I tried that, and I still couldn't get a lock. The only way I did get a lock was by installing the HTC GPS Tool (which I talked about in post 3) and using that app. Once I opened the GPS Com Ports, I got a lock in 20 seconds (indoors). I'm not sure if you tried it yet, but the HTC GPS Tool is really the only way I get satellite locks (with any ROM).

[Q] Few problems with my Desire, any ideas?

I'm using unbranded Desire with no mods/rooting, udgraded to the latest official Android 2.2 version.
Here are my problems:
1. People say that they couldn't reach me (number unavailable) while I was on the network all the time. Doesn't happen very often (or I just don't know that) but is really annoying when it does.
2. I am connected to my home WiFi but browser/other programs say that network connection is not available. I have to turn wifi off and on again for it to work. Can it have something to do with the "energy management" widget?
3. My phone is calling people. I get a callback from people saying I called them but they couldn't hear anything (phone was in my pocket). I was wondering if it wasn't the case when I am finishing a call and pressing the red button to end the call but someone on the other side hung up earlier and when I press, the "call" function is activated. However I remember 1 or 2 times when it was definetely not the case.
4. I desperately need a PDF reader that allows to continue reading a book in the place where I finished last time. At the moment I need to be very careful not to close the pdf reader app. When I do I need to look for the page, really annoying. This should be a free app (Google doesn't want my money, they don't allow people from my country into paid appstore )

Hello, 1&2 are really weird problems, they might be connected with the radio, can you check your radio version in settings\about\software\baseband. Some people had problems with the official OTA. Just to be sure - is your wifi alright on other devices and are you sure you have sufficient network coverage. If you download torrents with a crappy router you are likely to get problems. If you're in a low signal area it is possible to lose signal while your device is in your pocket e.g. closer to the ground, when you pick it up you see the bars, when it's in the pocket the network dies. One thing you can easily do is a factory reset , this way we'll find out if any software is causing the problem
3 - you might be turning your device on and then pressing the screen and then calling people, it is not unheard of . Ask them if they hear any noise like cars, people passing by and other stuff, if they do then that's the case
4 - search the market, there are a few, you'll need to try them to see which works best for you

If you only have a 2G connection, and are actively using data, all incoming calls will get diverted to voicemail because 2G only supports voice or data - not both at the same time. This is not an issue if you are in 3G coverage, when you can have simultaneous voice and data.
Note that this is a network side issue - 2G networks can be configured to prioritize voice over data, so that if a call comes through data is suspended, but as far as I'm aware most networks (in the UK at least) do not support this.
Regards,
Dave

I guess there is no point going to the store with a problem that cannot be reproduced :-/
Anyway I don't think it's something physical, I suppose software reset will fix everything.
I had that with Nokias, there was a main board problem (every now and then it said "invalid sim card"). Every time I sent it back to the manufacturer, it came back saying "software replaced, tested, everything ok".
Thanks for help anyway ;-)

Thanks Dave, actually my phone is set to automatically choose network type and I am using a widget to turn off mobile data since I have WiFi at home and only turn it on when I'm outdoors.
I heard that some phones cannot decide whether they should log into the 3G or 2G and that may be the issue. I have changed the settings to use only 3G, we'll see how it works.
BTW: Dave, is it London Ealing? I used to work in Ealing O'Neill's pub back in my student days :-D
