I've seen lots of people complaining about poor GPS performance - slow to lock, not finding many sats, lag, etc.
But I can't get anything at all from my Touch Pro. I've tried several radio roms, no difference, tweaking the registry settings, and programs called GPSID Settings, GPS Test, and HTC GPS Tool, all without any success.
I believe I should be able to use the HTC GPS Tool to debug, and see the actually serial output of the onboard GPS? But I can't even do that, whatever serial port I try to open I get the message "Failed to send NMEA command...". This suggests to me that the onboard GPS is not giving any response at all, rather than not being able to lock?
Can anyone confirm 100% what com port and baud I should be able to find the on board GPS with? Is there anything else I can try?
BTW, my external B/T GPS works fine with my touch pro, but it would be nice to have the onboard GPS working too.
TP GPS always uses COM4 and any baud (I've tried 4800 to 115200).
Your post is not a "thread" yet and I doubt it will be.
Just search the other threads.
a bit dettered when reading all these GPS problems. Once I've got mine I've had no problem at al besides it showing me a bit off the road in Google Maps. as far as for settings its always been the same COM4 Baud 4800

The default com port is 4. Usually most GPS application should be able to detect it automatically.

Sorry, I thought I did start a new thread, and I have searched - that's how I know about other people's GPS issues. But I haven't seen anyone else with the same problem as me yet.
I get nothing on COM4 at any baud rate.
TomTom says 'NO GPS Device'
HTC GPS Tool says "Failed to send NMEA command..." on COM4 (at all baud rates).
Google maps - when set to "Managed by Windows" just says Searching(0) and gives up after about 5 minutes.
When Google Maps is manually set to COM4 it says "Initialising.." in the top right corner then hangs, and then refuses to reload until I do a soft reset.
Is this what's supposed to happen?
No it's not.
You could have a hardware problem.
I had that issue after uninstalling google navigator 4 trial.Hard reset helped.
Also check Start > Settings > System > External GPS and make sure the Program Port is set to COM4, Hardware should be Port None and Baud at 4800 and Access tab should be checked to Manage GPS Automatically.
I have the "dreaded GPS lag" issue. I don't have this issue but I have found that my GPS is best with the Blackstone Radio 1.10.25.25. I still have to wait sometimes upwards of 3 minutes for a lock sometimes when the sky is cloudy but it seems to work pretty well.
I suggest you try the following
1. Flash to the radio I mentioned above.
2. Go to Start/Settings/System/AGPS Settings
On the General tab, uncheck "Enable AGPS
On the privacy tab, select the following options:
1. Enable AGPS location information to network services. Operator can get your location information.
2. When send location info. to network services: Send postion info directly
3. Close confirmation message after: 10 second
3. Go to Start/Settings/System/External GPS and make the following changes:
On Programs tab: set GPS program port to: COM4
On Hardware tab: set GPS hardware port to: (None)
On Hardware tab: set Baud rate to: 4800
On access tab: check: Manage GPS Automatically (recommended)

A lot of people have problems with the TouchPro GPS especially for pedestrian use...
From stock the TP GPS is quite unsable in car especially with TomTom 7 and totally unusable for pedestrian use.
After 2 weeks of reading and testing tweaks, here are the results of my tests and the applied tweaks to enhance the GPS performance
A. With Advanced config 3.2 http://www.touchxperience.com/fr/ou...ads/9-advanced-configuration-tool-32-cab.html
1. disable A-GPS
2. disable GPS logging
3. logfile name must be empty
4. old logfile name must be empty
5. maximum size of logfile must be 0
6 delete the files : \windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt
7. it seems that if TomTom is installed on a fast microSD decrease the lag(have to test to be sure)
With those changes car usage will be quite perfect
B. Then edit registry with TotalCommander http://ghisler.fileburst.com/ce/tcmdpocketarm.cab
Under: HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\
- Drivers\GpsOneDevice\PollInterval -> 100 (default is 1000)
- Drivers\InputBufferSize -> 512 (default is 4096)
- Drivers\OutputBufferSize -> 512 (default is 4096)
- Drivers\SleepOnNoData -> 100 (default is 1000)
- Multiplexer\MaxBufferSize -> 512 (by default not present, you have to create it)
Tests to be done with buffers at 256...seems to be a little better
Tests to be done with other PollInterval value...seems to "drain" battery
With those tweaks pedestrian usage will be much better but not perfect...I explain.
You have to walk for a least 250m in order to have a reposition with mouvement on the map (before that, speed is always 0km/h) and then if you continue to walk there is quite no lag...and the speed reflect reality
...BUT if you stops you have to walk again for a least 250m in order to have a reposition with mouvement on the map and then if you continue to walk there is quite no lag...
Very strange indeed...
I hope this will help people...please test and feedback.
PS : tests were done with
TomTom_Navigator_7.450.9028_R3_VGA_black_edition
GoogleMaps 2.2.0.16 -- http://www.google.be/gmm/GoogleMaps.CAB
GPSTuner 5.4 -- http://www.gpstuner.com/download/GPSTuner_v5.CAB

If that doesn't help you get a better, if not good, lock with your Touch PRO then you have to have some kinda of hardware problem.
I have an HTC Fuze from USA AT&T activated on T-Mobile USA and I don't even have access to T-Mobile's AGPS Servers and my GPS locks are usually relatively quick.
Good luck!

Rechecked all my settings, but they were all already as above. Still no joy. Only other possibility is that it's being crippled by the ROM I'm using - stock 1.90.206.4 WWE O2 UK variant, although no one else seems to be having the same problem. I am trying to avoid reflashing the main ROM, as it would take hours to get all my programs and settings back to how I want them. Maybe when the 2.0 firmware is released...
I guess it could be a hardware fault, but it seems a bit of a long shot. I really don't fancy my chances of trying to convince o2 that it's a hardware fault.
Try this...
1. Install and configure SecondToday to the left soft-key
2. Install HTC Home Plugin for VGA
3. Install GPSToday plugin and configure it to 5 minute manual-on
4. Go to Start/Settings/Personal/Today and disable all but TouchFlo 3D
5. On your new SecondToday, enable HTC Home and GPSToday
6. On HTC Home's Programs Tab, add your favorite GPS program(TomTom, Garmin, Google Maps, Etc...)
7. Start GPSToday by clicking on the little red box on the far left. It may take about 2 minutes on the first try(it's this way after every soft-reset) but after that it should be much faster. As soon as you are locked on to 4 or more satelites start your favorite GPS program that you added to the programs tab of HTC home.
If it works like it did for me, you should be set. I now get GPS locks in less than 10 seconds every "second time" since it takes about 2 mins after each soft-reset.

Thanks for that. I've given it a try and it doesn't get a lock or even see a single satellite for me. I assume the number in the green box that appears next to the satellite symbol is the number of satellites it can see? It never changes from 0 anyway.
I've never seen a single satellite with the onboard GPS, nevermind gotten a position locked. Beginning to think it's a hardware fault, or my phone got missed when they were putting the GPS in! Convincing O2 that there's a fault will be one thing, then I'll have to flash it back to stock, including the stock bootloader before I send it in.

That's why I put a string of dots on the end ot it...
Don't you think it's imminent, why would they release it for diamond and not touch pro?
I had the same problem for about 2 months, could never get a signal. It was solved when I changed ROM's. I actually tried like 7 ROM's and GPS didn't work in 6 of them. Once I tried RSW's ROM with updated GPS Drivers,,, I am able to always get a GPS signal now.
I do use 2 programs though.
1. QuickGPS to download GPS data.
2. Chartcross GPS Test to open my GPS Port.
Then I open up any GPS program and they all work. (Google Maps, Live Search, iGuidance)
COM Port should be COM4 obviously. When I've used a few GPS programs that "scanned" my phone, they all set the baud rate to 9600. You can't change the baud rate in Settings, but if you have to manually set your baud rate in your program, set it to 9600.
GPS reception significantly affected by case.
Just a FYI. I was a Fuze owner with significant problems with GPS. Could not get it to connect to anything for anything with anything. After trying everything I found on the forum I followed the instructions on this thread ... http://forum.xda-developers.com/showthread.php?t=473481&highlight=lock. and got a lock in under ten minutes. Put my phone back in the case and could no longer get a lock. It then dawned on me that my aluminum case was interfering with the gps chip. Did a bunch of tests which confirmed the reception improved drastically outside the case. It doesn't seem to influence the radio reception however which I find a bit strange. Anyway. My gps works reasonably well and I think people will benefit from knowing something as simple as the choice of case could have something to do with their gps reception.
Recently my Google Maps has not been able to lock in on my location closer than 1500 to 1900 meters. I have hard reset and reinstalled GMaps with no luck. I have seen tweaks for Sprint and TMo users and have read that most VZW users are having no problems locking in. Are there any tweaks that I can try for the VZW TP2?
there are numerous gps tweaks to change the cache settings if you search for them. also try using the program quickgps which comes with your phone it will download the closest satellite info. inside my building i cant lock on any sats but outside i can get between 8-9 and within 10 meters of my location
Make sure location is turned on.
If you do the quickgps program on the phone it will turn location on for you and download the closest satelites for you and you should get a lock in like 10 seconds when you are outside.
Unless you turn on location you will just get your general location with google maps, mine said within 2800 meters till I used QuickGPS.
I have duplicated your problem by unchecking the gps option after you open google maps and pressing menu and the down arrow. Make sure the location setting is on as prior post stated and then after you open google maps make sure gps is checked in the menu and it will say that it is searching for satellites.
also make sure you change your gps settings in google to com4 and a baud of 4800
you also have to re-enable the "use gps" after changing this
I was able to dublicate the problem aswell, by accedent >_<, anyway, make sure the location setting for google maps is selected.
confirming what others here are saying, that's pretty much what I experienced with GPS unchecked in the main right softkey menu. If you don't have that checked it's using cell antennas or wifi to approximate your position. "Menu" > "Use GPS" and it should work by default.

Leaving it set to the "Managed by Windows" setting works just fine for me. No issues, and definitely use the Quick GPS program, it saves a headache. In fact im sitting on my couch in my appartment on the bottom of three floors built on the side of a hill with 2 sides of earth, and I have a strong 8 to 9 sats.
I just got my TP2 yesterday and one of the first things I did was install google maps and I was getting result like the title of this thread "within 1800 meters" and it could be a mile off. also the sats were not locking at all. I realized that my position was based on the tower that I was connected to. By the way the google maps on my VX6800 never used the towers to triangulate a position but the gps lock were much slower. Once I ran the quick GPS in the programs menu it turned on the GPS to the right setting and now I get an accurate lock even inside within seconds.
Go to settings-all settings-personal-phone-cdma services-location setting and make sure that it is set to "Location On". If not, you are not actually using the GPS. With that on and with QuickGPS doing it's thing, you will lock instantly.
I have a Verizon TP2 that is two weeks old. It does not have QUICK GPS! Oh yeah, and the gps does not locate.
Do I?
Return it?
Hard Reset? (sounds like a lot of work)
Get the file somewhere?
I have had it twice to Verizon. They have no suggestions but are happy to see the device and get their hands on it.
Leaning towards exchanging it for a new one.

Hi everyone
I have a P3470+ (HTC clone from China) Phone (Hisilicon K3, 460MHZ, WM 6.1) and my problem is that whatever navigation software (or Google Maps) I use, the phone doesn't find any satellites anymore :-( It USED to work but now it doesn't?!?
Anybody know how to fix that problem?
Also, can I update the ROM? Where do I find an ENGLISH ROM (WM 6.1 or even 6.5?). I know how to set this phone into an "update mode", I also have a software called "IDT" from Hisilicon, the only thing I am missing is a ROM. Maybe this is the only chance to get the GPS working again?
Anybody know how to do a hard reset on this baby?
Thanks for your help and greetings from Germany

Download GPSToggle CAB from this link http://www.megaupload.com/?d=7VRBH5RS . It is called GPSToggle and is a Today screen app. It works best when installed to main memory.
Once installed, you will need to add it to your Today screen. From your Today screen go to Settings, then choose Today settings. Go to the Items tab and you should see BAF GPS Toggle at the bottom of the list. Click the box to have it added to your Today Screen. Close the Settings screen and go back to your Today screen.
Now, a little bit of info about your GPS. It will work best when it has an unobstructed view of the sky overhead. It should stationery (not moving) and uninterrupted from the time you turn on the application.
Some people can get satellite signals inside a building. I can because I live in a one-story condo. If you can sit outside with your phone for about 30 minutes, GPSToggle should do the trick.
On your Today screen you will now see an item called GPS with the word OFF next to it. Click the word GPS and the word next to it will change to On indicating that the app has turned on your GPS.
Now sit back, be patient and wait. If you're lucky and outside, the SIRF III chip in your phone should lock on within as little as 42 seconds (doubtful in your case) and as long as five minutes.
Attached to this message are four screens showing what your screen will look like:
GPSToggle 01 - Initial turn on. GPS is in search mode (no satellites detected).
GPSToggle 02 - GPS on. Communication beginning. 12 satellites possible.
GPSToggle 03 - GPS on. Four satellite bars displayed. Satnav not possible yet.
GPSToggle 04 - GPS on. Four satellites locked on. 3D satnav possible.
Note 1: I had not turned on my GPS today which meant it took about 2.5 minutes to lock on. This is not bad considering I am sitting in my front room. Normally, it takes about 60 seconds when I have turned on the GPS previously in the day and eperemis data which is satellite position and timing information is available from a previous session.
Note 2: According to most SIRF manufacturers, it takes three satellites for 2D satnav to occur. Most GPS programs can operate with that mode. Four satellites provide 3D satnav which is preferred.
See if this works for you. If it does, whenever you need to use your GPS, go to the Today screen and use GPSToggle to turn on the GPS for you which will quote warm it up for your GPS program. Once you see four green bars, you can turn on your GPS program and navigate like a champ!
You can read further about GPSToggle at this URL and thank the developer: http://www.freewarepocketpc.net/ppc-download-gps-toggle.html
Good luck!
Thank you so much for this detailed instruction, I really appreciate it!
I tried it, unfortunately it didn't work for me
After + 1 hour it still says: GPS on Seek: 0
I'm starting to believe that this phones actually has a hardware defect?!? Whatever navigation software or GPS tools I use, GPS is ALWAYS found, Comport is open and it looks like data is flowing but never does this phone find any satellites
Anything else I might try?
Thanks
There are two more things you can try (actually three but I will save the worst for last):
#1 - To help your GPS, it is best for WM to manage it (a recommended feature from Microsoft). Go to the Settings tab, External GPS (why it is called that on my Settings tab is beyond me). Then click through the screens to have WM manage the GPS. On one tab you will asked to choose a Port from which all your programs will access data. You need to use an unused Port. I recommend Port 8 but that is up to you. Previously Ports 1 - 4 have been used by other programs. 5 - 8 are free and supposedly TMS uses Port 9.
The reason for doing this is if WM manages the data, it will keep the GPS on and provide the resolved info to all applications. If the programs managed the GPS, they could selectively turn on and off the GPS and also block each other from using the GPS. You don't want that to happen. That is why MS recommends WM manage the data.
#2 - While I have never used this option, Assisted GPS (AGPS) is the second option. You activate Assisted GPS by going from the Today screen to Settings and then System. AGPS is one of choices on this tab. Once selected, AGPS settings page will offer the chance to Enable this utility. Click the circle next to Enable to activate this feature.
Assisted GPS will use an internet or cell tower connections to download Epheremis data to aid your GPS to determine what satellites are available to you during a given time period which is why charging is recommended. Be advised that AGPS can your data plan to access the internet and could cost you some money. Supposedly AGPS should be able to download epheremis data within a short period. The file is a small text file. But I don't do it this way and can't really advise on this although I do know theoretically how AGPS works.
#3 - While this is not the worst of options, you can plug in your phone nearest a wall that is not obstructed by being in the middle of your house or apartment and turn on the GPS. If there is a room with a window where you can leave the charging phone, that would be a preferred location. In some cases, it can take hours for a phone GPS to be found. You could do this overnight if not having use to your phone is a pain for you. Yes, you might to leave it unattended for a long time.
There is one more option but that involves downloading another program which hopefully will not be necessary. Please try the options one by one and see what happens.
Good luck!
Correct time set and its importance to GPS position resolution
Pardon me for what I now say but, I made an assumption and would like to cover that base. Is your time and time zone correctly set?
Global Positioning Satellites (GPS) use the time set by a GPS receiver as the entering argument to determine where your GPS is. When your time and its time zone settings are received, the overhead GPS will transmit to your receiver the epheremis data which is the location and times satellites will be overhead where your time is set.
Being off one minute, a couple or even an hour *might* not be too bad. But three hours (a time zone) or using AM versus PM will seriously affect what epheremis data is transmitted and used by your receiver.
Time zone is also a similar error. Off one or two zones and the wrong epheremis data will be transmitted and used.
To use an example, this would be like telling a friend you will be in Paris at 10 AM sharp when you actually are in Milan and it's 8 PM. If your friend were to look for you at the Eiffel Tower at 10 AM, do you think they would ever find you if you actually were in Milan?
GPS receivers suffer too when incorrect time or time zones are set by the user. Granted, the user should sync the time with their computer but even some users have incorrect time set on their computers.
Hopefully this is not one of your problems.
Thanks again for putting so much time into my problem!
I just checked the time, date and time zone, it's all correct.
I tried it with and without having WM manage the GPS, right now I have this function ON in the external GPS settings. Program port 5, Hardware port 6, Baud Rate 4800. I KNOW these settings are supposed to work because they did when I first received that phone. Igo8 worked perfectly with these settings
about #2: This phone does NOT have any A-GPS settings. I'm SURE I looked into the right place, I have another phone (a T5355+ Touch Diamond2 clone), that phone does have A-GPS settings and they are found right where you wrote they should be. So, nothing I can do about A-GPS settings on my P3470+ phone with the problem :-(
about #3: I have my phone in a room right under my roof right now, underneath a huge window, charger connected, hoping for a positv result. In that spot I was always able to find some satellites
What else have I tried before:
I tried using Quick GPS, I downloaded the data, no result. I also deleted the Quick GPS data, just in case, but it also didn't do the trick.
Anyway, I'll leave my phone under that roof window for the night, I'll post the result tomorrow
Thanks again for all your help, I really appreciate it
You're welcome, Colonel. Every time I see a post like this, I thank my stars that I have not had this problem. I was a Mod on another GPS forum and saw this frequently but half the time it was what we called in the military "operator error" or self-inflicted.
I wonder if you have installed other GPS apps and removed them? Reason I ask is that I've noticed with WM6.1 and above, that WM seems buggy when apps are installed and removed. I don't think it's MS's fault but what I call "crippled ROMs" that we are seeing. Not all ROMs are created equal if you get my drift. If you have a backup program like SpriteBackup or SPB Backup, you might want to do a backup and then a master reset or Mass Clear to bring your phone back to an initial state where the GPS drivers should all be present. I would save that for tomorrow if I were you.
I know it's probably about beddy bye time if you're in Germany. There is two more utilities I can recommend. The first I have a doc file on which I will paste here.
Winfast Navigator (WN) is the easiest to use in my humble opinion (IMHO). I have a Holux GR-271 that connects to my PDA as a NMEA receiver on Port 4 at a baud rate of 4800. Once installed, you can use your values to test your receiver from the first page displayed.
I have attached the zip file to this message. I think you can install the CAB file to your storage card. Once you do, you can use the settings you quoted in the first window.
Here's how another member reset his GPS using WinFastNavigator and how to set your values on the first page:
http://tjworld.net/wiki/Howto/ResetGPSReceiverToNMEAMode
While I would not recommend setting your SIRF chip to NMEA, one of WN's utilities will reset your SIRF chip if you want to go that route. I would have reinstall it to my phone as I did not need it for my phone.
Not sure why but xda could not attach the file. Here is a link to it:

I have the same problem with a phone like, ask the chinese rom, but not how to install on the phone , because apparently I need the driver (my pc does not recognize the pharos downloading clone mode), you use if you send the original ROM?
Hi everyone and especially Ronp76
The night under ste stars didn't do the trick
I was suspecting I might have a "crippled ROM", so I did a Clean Boot a "long" time ago, with no success.
O.k., I just installed WN, clicked on Port Setting, selected SiRF and tried to set it to Port 6, Baudrate 4800. I got an error message:
"Couldn't open the Serial_AGPS COM6 port!"
Same error message on COM1 and COM3, the only port I don't get that message is "Serial_BT COM2"
Bluetooth????
When I select that Port, WN tries to connect but nothing happens :-(
EDIT: I still had BAF GPS Toggle runnning, after turning it off, I didn't get the error message on COM6 anymore. But still WN is trying to connect to COM6 and is getting nothing :-(
EDIT2: I tried a tool called "GPS Port Scan" http://www.51spsoft.com/DownInfo/info30767.html, it searches for GPS, finds it on port 5 AND (?) port 6, when I open Port 6, I can see "data flowing" (see attached picture). But that's it, when I check the GPS status with this tool, it shows no longitude, latitude or anything :-(
While I would not recommend setting your SIRF chip to NMEA

@ssccll
I know what you mean, when I put my phone into that "download mode", connect it with my laptop, Vista is trying to find a driver which I also don't have. Since I couldn't find an English ROM for that phone, I haven't really worried about that (yet)
SatCE rogram recommendaton
ColonelZap,
I am sorry to hear that Plans One and Two did not work. I think you're right that something drastic has happened to your GPS and now it is not being found. Hopefully you got a one year warranty with your phone and can return it if my next couple of plans do not work.
I have Plan Three ready now and will work on Plan Four later. Plan Four involves WinFastNavigator and resetting your GPS. I will have to reinstall it on my PDA as I took it off when I made it a dedicated iGO8 GPS with TTS support. iGO8 and TTS use just all available memory. Plan Three is a program called SatCE.
SatCE is a pretty smart program that usually finds a GPS regardless of whether or not the user knows how to find its settings. Download the CAB file and install it to SD card memory. Start up SatCE and you will see the Initial Screen. This screen has interesting information once the program is locked-on to satellites. Please note that since I launched my SatCE from a cold start with my Clone's GPS, it has no satellite information.
From the Edit menu on the taskbar, choose Location. The SatCE Location Screen will appear and you will see that SatCE is using the GPS location for its eperemis data. Change this Location to the city nearest you. Then tap the Calc button on the same screen and go back to the Initial Screen.
If your GPS works, the numbers should begin to change with the Sun and Moon information the easiest to verify. Based upon your time, you should be able to see that the Sun's azimuth and elevation are correct. By setting the Location, SatCE will force your GPS to use this Location as its present position in the epheremis data equation to locate satellites.
SatCE works really well and displays some pretty neat pictures if you click on the Icons next to the Edit menu.
Good luck and I will work on reinstalling WFN.
I am just about done setting up my PDA with WFN. In the meanwhile, I will post a more detailed URL for WFN as there may be more info there that I have glossed over:
http://www.pocketgpsworld.com/winfastnavigatorppc.php
To get back to one of your questions about changing from SIRF to NMEA, I am unsure because we are dealing with Clones and I yet do not know all the specs for SIRF III which is supposedly the chip used in our Clones.
Supposedly with previous or older SIRF chips, you could change back and forth between NMEA and SIRF because that was built into most chips. I don't know if SIRF III has this capability.
One thing unknown to the average bear or GPS user is that programs can tweak your GPS chip. GPS chips have flash ROM memory like our Clones' memory. Instructions or new data can be written to flash ROM which can affect how your GPS chip operates. OR, instructions can be written and cause your chip not to work.
I hope that maybe one of your programs wrote some bad instructions which did not damage your GPS chip but reprogrammed it making it invalid. Since it worked previously with other programs that is the more likely scenario versus it failing but hey stuff happens!
I will leave you with these thoughts while I go "play" with WFN on my PDA. Colonel - this is going to cost you beer (just kidding)!
WinFast Navigator Reinitialization of GPS chip
ColonelZap,
I think you broke the code on using WinFast Navigator BUT just in case and to allow others to follow along, I will now detail how it can reset a GPS chip.
From the previous Initial Screen, a user selects Port Setting and inputs the appropriate values. If these values are unknown, they can be found by going from Today/Settings/System/External GPS. These values are set from the Initial Screen using the attached WFN Port Setting Screen. Select SIRF and your appropriate Port which can vary from Clone to Clone and HTC to HTC (this stuff does apply to HTC regular phones too).
At this point if you had a working GPS chip, you could click Connect from the Initial Screen and should get a message to the effect that your GPS was found. If not, then we will now get into some of the tweaking found from this URL:
http://www.pocketgpsworld.com/winfastnavigatorppc.php
Once you have set your GPS chip values AND know them to be correct, you will reinitialize your GPS chip using the WFN Reinitialize Screen Page. This page is found on the Initial Screen by going to Command.
Click Command and you will see the WFN Reinitialize Screen. You will select Factory from the Reset Modes available. Click OK and go back to the Port Settings page to see that the values are what you initially set.
Click Connect again and cross your fingers that your GPS chip was reset and it now back to a working Factory Mode.
BTW, WFN's Reinitialization page is good for other things too. If you ever travel more than than 10 miles with the GPS chip off, epheremis data will be written to your GPS track log with your last known position. This last known position is used to locate satellites.
Like the previous example of telling someone you're in Paris when you're actually in Milan - if your GPS thinks it's in one place when it's actually in another, this can delay the Time to First Fix (TtFF). Basically your GPS chip is going from a Cold Start with bad data.
You can force the GPS chip with WFN to first Connect using the Initial Screen page. WFN remembers the values you set. If by chance, the Connect is taking too long OR you have travelled a long distance say by plane, you can exit the program and start it again.
Then you will go to the Reinitialization page and do a Cold Start. This will clear the track log and force your GPS chip to use its time + time zone to communicate directly with overhead GPS satellites.
One more note and I found this by accident. In the same way GPS chips can be tweaked incorrectly, they can be tweaked in a positive manner. If you look at one of my PDA's WFN Initial Screen, I tweaked the GPS chip from a baud rate of 9600 to 57,600.
Older GPS chips were set at lower baud rates when they were fully capable of higher rates which is kind of like a modem that can use various baud rates. By using the WFN Reinitialization Screen page, I reset mine on the NMEA tab to 57600. I have not checked this with the SIRF chip on my clone but will do so later this afternoon.
Good luck again to you. Hope this works!
SatCE Mission failed
I followed your instructions, my city was even listed Clicked on calc and numbers started to change on the main screen. No satellites, though
I couldn't tell if the sun's position is right, it's pretty cloudy, I couldn't see the sun.
When I clicked on the sat-symbol in the taskbar it reads
"GPS not activated"
WN Mission:
Here's what I did:
Port Settings – SiRF – Com 6 – 4800 Baud – ok
Then I clicked on command, selected Factory, selected 4800 in the SiRF settings, pressed ok.
Now, here is the "funny" thing: As soon as I pressed the ok button, the main screen came back up and it reads NMEA in the bottom left corner? WHY NMEA????
Other than that, nothing happened
Man, I really owe you more than just one beer

Rule of thumb regarding Sun:
9 am - 090 degrees East
12 pm - 180 degrees South
4 pm - 270 degrees West
I think SatCE had the same problem as the other programs - your GPS has been reset.
I don't think I remember reading or seeing a WFN Factory Reset not bringing a GPS chip back to its original settings. On the WFN Reinitialize Screen page (attached), go from the Reset tab to SIRF tab. Insert your proper values and click OK.
You could go back to the Connect feature but if it was me, I'd do a soft reset after exitting the program. Do a soft reset and then run the program again. You may wish also to repeat setting up the SIRF values on that tab and then doing a Factory Reset to see if that helps. I seem to remember doing different combos but it has been a year or two since I did all this "black magic" but it was PFM when my GPS came back.
You might also want to look at the URL in my previous message to see if I missed something. I know that that URL reads like a doctoral dissertation but it saved my bacon when my PDA's GPS was reset by a program.
Then you can look at this page:
http://tjworld.net/wiki/Howto/ResetGPSReceiverToNMEAMode
That user wrote about how his GPS chip worked with both SIRF and NMEA. I would think our Clone's SIRF do the same. If nothing else works, you could set NMEA and use the values he suggests for making a SIRF act like NMEA with these values:
GGA 1
GLL 0
GSA 5
GSV 5
RMC 1
VTG 1
MSS 0
User 0
User 0
User 0
I have to run but will leave my computer how so I can tap into it and maybe respond on the fly! Good luck!!!
BTW, on one of your combos, please make sure you check the SIRF tab and then ACTUALLY do a Factory Reset by clicking the OK on that tab. I know you probably did this but just want to make sure you clicked OK on this tab.
You could also do a Factory Reset followed by a Cold Start immediately after that.
Gotta jam!!!
Hi again
I re-did everything, softreset and EVERYTHING.
The "bad news" is, when I use the Post Scan Utility (see my Post #9), NOTHING is found anymore
I also have the feeling, that WN is not really doing anything? Whenever I restart it, the baud rate is back to 38400, it doesn't take my 4800?!?
I'm also a little confused why I only get Port1, 2 ,3 and 6 offered when I go to the Port settings. The only port accepted is port 6 and this port is called "Serial AGPS" why "AGPS"?
I'll play around a little more, maybe I'm doing something terribly wrong?
UPDATE:
After I did the NMEA thing, I used the port scan tool again, this time it found GPS on Com5!!!! Too bad WN doesn't offer me that Comport
UPDATE 2: This port scanning tool always seems to find the GPS at the port I set under "Programs" in the external GPS settings, NOT the hardware port.
Looks like the Colonel is getting plenty of help!
Sorry about the problems though. But this has been a really interesting lesson in how GPS chips work. Bookmarking this thread right now so I can come back to it later (here's to hoping that doesn't need to happen! )
BTW Colonel.. I forgot to mention to you (and in my little video) that I am also using the Windows Mobile utility for managing my GPS connection. I think its called GPSID Settings (cab attached). I have the checkbox clicked to manage the connection automatically. After doing that, I open the GPS viewer to bring the GPS chip to life before launching iGo.
AGPS usually stands for Assisted GPS which means that your GPS is being "assisted" by your data plan and/or cell towers to get epheremis data. I did not think about that. You will find AGPS on Settings/System/AGPS. If it is on, I'd recommend turning it off as it should be "helping" you. You can about SIRF and AGPS here:
http://en.wikipedia.org/wiki/SiRFstar_III
http://en.wikipedia.org/wiki/Assisted_GPS
I noticed in your second picture that the GPS was found on Port 5 but you say that you have been using Port 6.
If and I do recommend WM6.5 being set up to have manage GPS data, WFN needs to know the real or actual Port when you do a Reset.
Serial GPS also means something but I have my mind on what I'd doing right. I've seen it some context and feel it may be a factor. . .
SIRF, Port 5 would be my bet if GPSViewer found it there.
Colonel,
When you go to Settings/System/External GPS, what Port does WM report your GPS as? That report or Port should be the one you focus on resetting or re-initializing.
I'm aware of the GPS issues with the Samsung Galaxy S. I have the Samsung Galaxy S 4G and I'm wondering if anyone with this phone is experiencing difficulties getting GPS to lock in.
Within approximately 10 minutes, I can see in the GPS Test app about 3 satellites in view. Given enough time, it picks up a few more and eventually locks in.
I've read about the Super GPS fix and the hardware fix but I'm not sure if it would be wise to try it on this phone since the fix was meant for a different model and I don't see any mention of anyone trying it on the GS4G:

Locks quickly for me without any "special" settings or apps. I even have network-based location always off on my phone since I don't want Google tracking me all the time.
The first lock may be causing you problems if the orbital data hasn't been loaded recently enough.
I have read that GPS Status has helped some by causing the orbital data to be refreshed.

I have a Samsung Galaxy S 4G and a Vibrant, both are horrible with GPS, they both take forever to get a lock and many times they never get a lock and Samsung is less than helpful. They had my Vibrant for three weeks and sent it back with nothing changed.
mine has never taken more than ~30 seconds to get a lock, even if that 30 seconds sometimes feels like "forever".
this is my first GPS-equipped phone, so i don't have anything to compare it to, but once it's locked, subsequent locks take less time. maybe i just got a "good one"?
I have a Vibrant and an sgs4g. There is no comparison between the two. The sgs4g takes about 5 seconds to lock, The Vibrant I've waited literally 40 mins and still never got a lock. It could be the app. Are you having any trouble with google navigation taking along time or just the gps test app?
I know this wasn't directed at me, but I share the same GPS problems.
This issue occurs in all GPS Apps, including Google Navigation. It simply says acquiring GPS....
The GPS icon flashes like it's working, but its not doing anything.

Just kidding, I bought the app. So far it seems to be working well; after doing everything my phone was actually picking up FIVE satellites.
Not working right now, though. I contacted the developer for some help, and I'll post his reply/an update soon.

Remember, credit goes to "Bade" (which credited XDA forums anywho) of samsunggalaxyforum.com
Running Copilot Live (GPS Application) and finding location took less than 5 seconds indoors.
To check some info out, I ran GPS Test, and saw "In View" Satellites was 9, and "In Use" was 7. (both were 2, to 0 respectively...previously.)
Running GPS Test (another app, different) came up with my location in less than a second.

My GPS was working but I wanted to mess around and check on your findings. I tried to get this to work but it took quite long looking for Satellites.
I noticed when I went in to modify the SUPL settings, it was set to custom config. Made the changes according to your post and like i said before, it took a while so I stopped it. changed the settings to auto conifg and BAM! pulled 13 satellites and locked in within seconds. I do not know if its due to my location but Im working great on Auto Config.
this post is more of an FYI rather than a fix. Hope you guys get yours fixed either way.

On the first try, you have to let "Get Position Test" run for around 10 minutes (The 3 minutes on the original post I said might've been a stretch).
Trying Auto Config, I'm getting similar results, though with the custom settings I had more satellite lock-ons.
Custom:
12 SAT, 10 CONNECT
Automatic:
11 SAT, 7 CONNECT
After doing this, the GPS data should stay downloaded on the phone so future satellite searches are MUCH quicker.
Thank you for your input by the way..I appreciate it
My phone has always find satellites and locked within 30 secs. One day I started messing around with settings and came to find out my gps was no longer locking on any satellites at least for 10 mins. I bought the gps aids v2 app from the market then tapped on gps doctor and tapped on "regenerate" (it regenerates the gps data folder) it made my phone boot up. Since then my gps has been workin excellent after that.

I have the gs4g and tried GPS AIDs with some improvement . At the most I would lock onto 7 satellites when it felt like working. I lifted the contact as indicated in the thread above. I then deleted the old GPS data. Then in GPS AID I regenerated the DATA and rebooted. Now i get 12 locks on satellites all with green signal status. Very please. Google maps Locks on with in seconds....

I think I spoke too soon. I tried this in Calgary and it was great. I'm now in Toronto and I haven't gotten a lock since I got here on Monday. Tried messing around with the settings again, but just won't lock on. Also tried auto config to grab SUPL info from my provider, but that didn't work either. Still working on it.
Start over and flash krylon deoxed with odin, cwm, bionix. This resolved my 10-15m lock times completely. Now I get a lock in seconds.

Amazing!
I tried this and got accuracy within 3 meters off 10 satellites. Before, it was about 80 meters. Just awesome.
You don't need launcher pro to get into LbsTestMode. In your phone's dialer, just type *#*#3214789650*#*# and it'll go into it.
As for what you suggested about going in and messing with the settings, the first lock takes forever because you've wiped out all the ephemeris data by deleting. It starts looking for satellites for your first lock which takes a while with no ephemeris data. Once it gets a lock, it starts downloading ephemeris data and subsequent locks are significantly faster because your phone now knows where the satellites are.
AGPS helps reduce the lock time a bit (by using mobile location and the SUPL server), but not by a huge amount. The largest reduction in time is due to the fact that you have updated ephemeris data. If your ephemeris data is outdated, your lock times will go up again.
If you don't believe me, try this: get your lock. Then shut off your GPS by using the pull down panel. Leave it off for at least 24-36 hours. Then try to get a lock again. It's going to take a long time again...
I've been tinkering with the GPS on this phone for a while now as well as my GF's Vibrant. There's no doubt in my mind that the SGS4G is improved over the Vibrant, but it's still not great.
I've also pulled apart both of these phones and done the hardware fix by bending the little tab every so slightly. Made a significant difference on the Vibrant which was having a problem maintaining locks and the GPS signal was bouncing all over. No noticeable difference on my phone.
My only conclusion is that the antenna on these things are poorly designed and just take a long time to get an initial lock. Once locked, it's pretty solid. Other phone manufacturers have GPS that work better though. No reason why Samsung couldn't do better.
Hello all, I got a brand new Nokia 3 couple of days ago and today I enabled the location but it doesn't work. The location in the map is jumping like crazy. Even in the country with open sky I am not able to get the accuracy better than 50 metres. The location sometimes improves for couple of seconds but then seemingly resets to the original large error of 100 metres. Battery saver is always off, Location mode: High accuracy.
I tried the following steps:
1) turn Location off and on
2) turn Airplane mode on and off
3) turned the phone off and on again
4) updated Google maps, cleared Google maps cache
5) installed GPS Test app and it shows that the satellite s get poor signal 13 visible, 6 used but only orange quality, no green. Even outside city on flat terrain. An the satellites occasionally disappear.
6) turned of Battery optimization for GPS Test app, Google maps.

So I tried some more steps following the guide at "Technobezz - How To Fix Android GPS Issues" but with no sucess:
7) run Google Maps in Safe mode
8) clear GPS related apps cache data
9) clear all apps cache data
10) wipe cache partition using recovery mode
None of these additional steps led to success. The GPS position is still hopping like crazy.
I got pointed to a wider problem on another Android forum. The issue is likely due to the use of the Mediatek MT6737 chipset. Mediatek chipsets are infamous for GPS problems for several years. I was not aware of that when buying Nokia 3 as it is my first Android phone. There are many Youtube videos suggesting fixes for various Mediatek based phones, but none of these actually work on my phone or they require root access.
I am confused by the fact that NONE of the reviews I have read had ANY complaint on the GPS performance, except the one at "Trusted Reviews":
GPS proved wildly innacurate, often pinning my location a few streets away in Google Maps.

The quoted behavior is basically what I am seeing with my Nokia 3.
This is especially worrying because I had absolutely no issue with my previous budget windows phone. There are no complaints on the GPS quality whatsover. Are the reviewers even trying the GPS outside? Or is this a "standard" behavior on Android phones?
Can any Nokia 3 owner confirm their GPS works flawlessly? There is no hopping, the get GPS FIX quickly and don't lose it?
Am I the only one with my Nokia 3 being defective and should I return it back to the shop? My Nokia 3 GPS (Mediatek MT6737) is constantly getting weak GPS Fix losing it in a few seconds just to get it back for a short period of time rendering it useless!
Hi,first sorry for my English.
I have the same issue with GPS, I return my phone back to customers service, now i recovered it, ans they said "problem solved" . I try the gps 5 min later with google map, and they solved nothing...i have the exact same issue, it is hopeless. I plan to go back again to the customer service.
I had this issue wit nokia 8. On the Nokia forum ( link below ) there are other cases ( at least for Nokia 8 ).
Unfortunately, I returned my phone.
In addition, there is no Nokia response up to this moment regarding this issue that seems to be cross model.
GPS issue on Nokia 8 ( Nokia Forum )

Hi, I'm having the EXACT same problem on my new Nokia 5. Worse is that I'm a surveyor by profession, so imagine using a phone with messed gps. I've tried all "fix gps issues" suggestions I can find, still not working. I'm definitely returning the phone!
P.S: there is also the really annoying LOUD push message beep at the end of calls. It's so LOUD and ANNOYING, like wth?! Turned off sound notifications I can find, still there.
UPDATE: Nokia GPS Issue FIXED!!
So I did some more digging around and I found this Nokia Forum discussion topic on the same GPS issue: (oops, I'm new on XDA, seems I can't post outside links. No link to Nokia forum then). Anyway, thanks to user1511570178684 who somehow traced the problem to Android 7.1 Battery Optimisation settings. In his/her words: "...Yesterday I disabled battery optimization for LocationServices which seems fixed the issue. Also earlier I disabled optimization for Maps. The Optimization menu is a drop-down in the top right corner under the Battery... One or the other had fixed the problem."
Basically, go to Settings > Battery; from drop-dwn menu at top right, select Battery Optimisation. You'll likely be shown "Not Optimised" list first; change the list to "All Apps" (from drop-down menu), then look for 'LocationServices' and 'Maps'. Change their options to "Don't Optimise". That's it, GPS issue fixed!
My GPS (on Nokia 5) is now working ok. GPS test still takes a minute or two to locate satellites, but accuracy is much better ( up to <5m in open sky), and no more jumping around like Mikey mouse.
I also changed my Location settings to Device Only, so it uses only GPS signals in positioning (instead both GPS, WiFi, network signals, etc, which may introduce errors - never mind that "High Accuracy" nonsense).

I'm also facing the GPS problem with my two-months-old Nokia 5 - the phone doesn't see any satellites. I sent it to Nokia Mobile Care to fix the problem, they returned the phone after a week as "Returned unrepaired - fault not found"
NOT FOUND? Have they even tested it? I doubt that...
Now I tried what you wrote here but it still isn't working I will never buy a Nokia phone again. Two months and no GPS
