Hi all,
I've read through a couple of the really long threads about GPS here but can't seem to find an answer. The problem I'm having is in TomTom (latest version posted here) it can see several satellites, and they keep going up and down, but it doesn't seem to actually lock on to them, they all remain gray. It takes about 10 minutes or more to actually get a lock.
I'm using the Blackstone radio 1.10.25.25 but it doesn't seem to help.
I've tried all the cabs in a lot of those threads, but still no change.
Am I missing something really obvious and is there something I can do to fix this?

Hiya,
Yeah, I've tested those settings from other threads. Didn't seem to make a difference to the lock time. I also use QuickGPS and have tried both on and off aGPS.
What I did just notice was that it had all the bars grey in TomTom, and wouldn't lock on. I quit, went into GPS Test and it locked on quickly. Then went back into TomTom and it locked on pretty much straight away. Any ideas what might cause this?

I always use GPS Test till it locks on. Then I close and load up the nav software. Otherwise I get mixed results. Da_G is making some progress as I type into the cause of the lag issues. It looks like we should set the polling back to 1000 since the gpsdriver.dll is telling the radio to only spit out data every second. That may help you out also. If I figure out anything else I will post back....good luck..I think we are getting close to a fix for these GPS issues....
I think this is the first GPS thread I found here going through the pages.
Fuze/TP sometimes take a full timeout in google maps the first time after a flash/reset. Then it's hit or miss. It can be fast in a field or fail.
I'm only adding this because I bought a new unlocked 3G Diamond. I've done some rom flashes, and with NO gps data downloaded, it never takes more than 6-8 seconds to lock on gps. And that's no matter where I am, in the house, at work, in a field. There are no exceptions at all.
This does lead me to believe it's the hardware, not the software. Diamond stock radio is 1.00.25.08.
Just my 2 cents.
please give a shot
Oh I threw that phone away a long time ago. Someone else can try, and maybe it'll help.
TURBO GPS fix on Touch Pro
(contrary to many of the GPS fixes offered on the net)
I read a lot of fixes on how to make the Touch Pro lock on to GPS faster. Being an ex-owner of toshiba G810, which is the fastest GPS PPC i tried ever before, and noting that it uses the same GPS chip as in the Touch Pro. I tried to emulate the settings in the registry, and i got an excellent result, so would like to share that with you.
1) Many of the fixes on the net talk about turning off the A-GPS , i think this is "wrong" thing, cos when A-GPS is turned off, it would not be able to use the valuable satellite data downloaded from QuickGPS. Therefore, i use Advanced Configuration Tool to turn it back on (ENABLED).
2) I changed the HKLM\SYSTEM\CurrentControlSet\GPS Intermediate Driver\Drivers\GpsOneDevice\PollInterval -> 500 (default is 1000),
which is the same figure as in my Toshiba G810 before.
3) keep the log files untouched, i.e., DO NOT delete:
\windows\GPSLogFile.txt and \windows\GPSLogFileBack.txt
(if you have deleted those 2 files before, just create 2 blank .txt files with those filenames and put them back in \windows. When new GPS data comes in, it will append to the blank files, older data get deleted once reached the 32K limit set below.)
4) keep maximum size of logfile to the default which is 32K
Voila, now my Touch Pro always get 4 to 5 BLUE bars on my mapking (which mean dead lock on!!!) And it it wont fluctutate lock on and off intermittently.
Really urge you to try it, and let me know if you get the same results~~
Cheers everyone!
(For those who dont like tweaking with registries manually, krish_nank has been kind enough to make it into a .cab which i attach here.)
nice experience, i'll try it

Please write back to see if it works welll for you. And make sure you use QuickGPS once afterwards to get the satellite data before you start GPS.
I don't have any kind of data connection with my network so AGPS is useless for me, however I did try changing the polling from 1000 to 500 and I managed to get a lock with GPS test within a few minutes inside my own house! Can't remember getting the same results before.
I can only agree that
1 - touching log files is BAD.
2 - reducing poll interval will improve the GPS lag slightly
3 - keeping A-GPS up - in my country there is no A-GPS data available since thats the data provided by the provider over the local network cells. I dont think it has anything to do with the data from Quick GPS. But i might be wrong. Anyway, Quick GPS is your friend.
4 - if you have fix problems its usually either not having Quick gps data or trying to get a fix in a bad area or under a shielded windscreen.
overtweaked?
I changed the pollig interval to 100... is it milliseconds?
I haven't tried it yet but would it be a battery drainer like this (100)?
Actually I was hoping to reduce the delay of map in garmin or oziexplorer (which are my favourites) in higher driving speeds. I tried garmin while driving over 200 km/h and there was a damn nasty delay on the map. Of course it was a stupid risk to watch the screen during these speeds
I tried 1000 (default), 250, 125, and 64 Pollinginterval and none of them were as fast as 500.
well it would be slower because you are polling to often then. best thing to do for your gps speed is update your radio to 1.12.25.19. it doesnt take long to do. then make sure agps is enabled and update your quickgps data. increasing polling from 1000 to 500 might help but i havent tried yet.
ok i changed the polling and with my radio and quickgps i got a lock in under 2 seconds. i havent seen any gps device that could do that.

Thanks for your testing.
It seems that Toshiba G810 polling setting (i.e. 500) really works for a lot of us.
I was originally so amazed at how G810 could do it, and was so sad to see how bad my Touch Pro (which costs twice compared to the G810) is performing.
I'm glad at least now i can make my Touch Pro just as fast.

I have not had issues with mine with warm or hot starts (most was 30 seconds). What I need to know is from a cold start, how long it takes to perform a fix (you can verify using the HTC GPS tool).
To do a cold start, reset the unit with the button near the USB connector or if you have StartXP, use that.
I think wildboy did do a soft reset, it's kind of standard on XDA.

Without AGPS? Or is quickGPS similar... can't remember I forget now
agps needs to be enabled for quickgps. agps hindered gps on older radios. the newest radio works really well with agps and quickgps.

I kinda figured as much, but I just want to be sure. Mainly because with my current settings I am getting the same performance, except when I have a cold start. I am trying to figure out a way to get better cold start performance.
Thanks a million .. your tweak is working great. now i can get my GPS locked in 7 seconds
Once again thank you.
omg, this worked for me indoors
I never played with the Log file....
I do not have a GPS*.txt file in my windows folder, using EnergyROM 2.0 4.12.09...
Will those/can those files be generated by a program other then quick gps or visualgpsce?

Just install AdvancedConfig, this will allow you to edit the buffer size of the log files and verify their are log files in that ROM. Then you just need a Registry Editor to adjust the polling time.
Pretty strange but I haven't modified mine at all and it locks on in about 10-15 seconds which I think is pretty good, or isn't it?

Sorry, slight miscommunication..
I'm using EnergyROM 2, and i'm familiar with Adv. Config & Registry editing..
Default setting was no logging, and I can't point adv. config to the log file that doesn't exist.
If i just make ablank log/text file, and point it, will that work? Or do the log files need to have certain information in them in order to not screw up?
I am currently following a few websites to keep my news upto date with my ATT fuze. I have tried just about every single possible solution to get my GPS to work. Disabled aGPS, tried GPSTest, flashed various ROMs, tried various GPS programs, change poll interval to 500 ms, etc, etc.
I have owned this phone for 4 months now and I have yet to get a satellite lock to work. The closest I ever got was GPTtest running showing 6-7 different satellites in view, trying to connect to about 3 of them. I left that running for nearly 2 hours, and no luck. Whats the deal?
Please do not tell me to use the search function because I have searched XDA as well as google, and they all end up in the same place of speculation on why the GPS might not be working, but none of the said methods actually make it work.
It works man. I ran 6.5 beta with Google Maps installed. Took me to a location I've never been to and back.
xgm541, before using AGPS, do you have the right gprs settings for your phone? Have you confirmed that your gprs works?
Anyway, for the gps, read up on my thread about me finding an alternative way to get a better fix.
HERE:
http://forum.xda-developers.com/showthread.php?p=3514443#post3514443
Also, make sure you flash your radio if possible. Read up on the radio thread and i am sure other ATT users have posted the performance of GPS based on the Radio.
I am not an ATT user, as i am from Malaysia. So i am unable to help you on the AGPS part.
I second arvin's suggestion on flashing a radio. If you're in the US, I highly recommend 1.12.25.19, I have AGPS and GPS logging disabled, use GPS Test and always get a cold fix in less than a minute outdoors.
yeah ive got no issues with it, used it last weekend in the car and worked perfectly.
GPS definitely works. Flash the latest leaked AT&T rom, and just try it out. Don't flash cooked ROMs but the stock leaked ROM. If GPS doesn't work in that ROM then something is wrong with your particular phone. I'm in California and I get locks in under 7 seconds, and I'm using wm 6.5
GPS is about all that im unhappy with, on my fuze.
It does work, i placed a 3 stage multicache using only my fuze with googlemaps/GCz last week and everyone whos found the cache say my coords. were almost dead on. (coords were an average of around 20 readings at each site)
My trick (doesnt work fast but it works) is to turn on gmaps let it sit there for
1 min while it gets a lock, then switch to my gps (geocache) program and i have nps. I cannot get any other programs to lock or hold the gps without first running the googlemaps program. And everyonce inwhile as soon as i turn it on ill lock up 10 birds. Doesnt make much sense, and i too have played with all i could find (agps,baud,comport, windows settings etc)
good luck
I am using the standard HTC-ROM. All of these settings have been extensively tested in Europe the Netherlands. These are really the optimal, after testing many buffersizes, pollintervals etc. The most crucial one is PollInterval and SleepOnNodata needs to be equal or larger than PollInterval. Disabling or enabling windows GPS logging does not matter, as it is only used for debugging according to MSDN. If you start using AGPS (I Don't!) then make sure all settings are correct to download the info from your provider (mine does not support this and thus it is turned off in these settings).
0) Assuming that the hardware is still OK do the following:
1) Go to settings > System > external GPS.
Check if all options are still normal.
Program port is COM4.
Hardware port : none.
Baudrate : 4800.
Access: Check automated GPS control.
NOTE that an external connected GPS (e.g. Bluetooth device) unit will have a baudrate of 4800. The internal which resides at Com4 has a standard baudrate of 57600. These settings need to be checked to make sure they are still this way and it will also give Windows automated control of the GPS system.
2) You need to install Advanced Config 3.3.
http://www.touchxperience.com/fr/out…ol-32-cab.html
With Advanced config 3.3 under GPS:
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
After these settings the tool will soft-reset your mobile.
3) Then edit registry with TotalCommander
http://ghisler.fileburst.com/ce/tcmdpocketarm.cab
Don't make any errors here, check your steps carefully.
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, make a Dword value)
After these settings are in place, restart / soft reset your device.
4) Run the program QuickGPSfix and download the new data.
This step needs to be repeated anytime it is outdated.
5) Download and install the HTC GPS Tool.
http://rapidshare.com/files/84815853...C_GPS_TOOL.cab
Upon starting it should show COM4 and a Baudrate of 57600.
Go outside the house, preferably with good weather.
Hit the "Open"
Hit the "Nav. Int."
Leave all as is, no need to change the options.
You should now start to see the GPS data flow over your screen in the grey area. Wait patiently, the first fix can take up to 10 minutes (afterwards it wil go faster). If it fails it sometimes seems to help to move around a little bit and to reboot your device if it takes way to long (+10 mins).
See if you have any red bars below the satellite numbers (signal strength per satellite) When you get a fix, the bars and satellites to which it is connected will show up green. If there are no red bars here, no data flow etc then there is something wrong with the ROM / radio combination and your phone.
Close this program if you have a fix.
6) Start-up Google maps. Wait for it to download the basic map information, so you don't have any interference from the "now downloading data" message. Then start the GPS use. Fix should now go fast. Once it has a fix you can start moving towards your destiny.
From now on use HTC GPS tool to get a fix.
Close this program, start the program with which you want to use GPS.
Good luck, Jouke.
GPS works good enough.
I definitely suggest radio 1.11 or later.
Of course best to get the whole 5.05 ROM.
Work great! To nearly perfect location!
I'm using the ATT test ROM and google maps with street view.
Works better than any phone I've ever owned when the test ROM or a derivative is running the show. Matching radio must be used. I've tested the Ralphael 1.12.25.19 (shipped with test ROM) and the Blackstone 1.13.25.24 so far.
Messed around a bit more and got instant 10 sats after changing to
baud rate of 9600 on com4... i guess the windows management of the gps is most of the problem (?).
I had the same exact problem as you. I couldn't get a lock no matter what I tried, I was thinking of going back to the Kaiser. I then decided to change my radio from the .32 to the 1.12, left GPS Test running for about 30 minutes, still no lock.
I was standing on the balcony of my apartment....
Then..... when I got into my car I tried again and I got a lock in under 30 seconds..
Not to insult your intelligence by any means. BUT, are you outside in the open?? Because once you have set those settings that everyone here has asked you to do. It should work.
Here is what I did.
Change the stock radio. I believe this to be the main culprit. 1.12 works good. then set your standard GPS settings to Baud 96**** and to COM 4. Run GPS test in the open, outside.
It should work. I sometimes mess around with the AGPS settings. I mainly leave it off because I honestly have no idea what it is.
I get a lock in under 1 - 2 minutes every time. However, I am having a problem with the speed of the GPS. I use TomTom 6 and sometimes my triangle cursor wiggles oscillating from left to right. I don't know why. and also sometimes it is delayed.
I have yet to find a fix for this, I would be glad if someone can please help. I'm not sure if this is a video problem or a GPS problem.
Worked Both Ways
I've had my Fuze since just before ATT released them, and the GPS worked fine for me, once I could get a signal, obviously a big issue. I followed all of the GPSidfix cab etc and they helped, had to load GPS Test to prime, once it got a full lock and said running I could use Google, TomTom 6 or Livesearch and get instant locks.
I don't flash ROMs, but finally broke down and put the ATT Leaked Rom on my Fuze, and bammmmmm. GPS is almost instant in every single one of those applications, we're talking 2 or 3 seconds when I'm outside. I get locks in my house when I'm by the windows as well.
I haven't driven today, so I can't speak to lag etc or other issues, but once I knew the lag it never bothered me that much. Overall, the new ATT Leaked ROM has been awesome for GPS.
i never changed my radio, am using the stock radio on a fuze bought 1 1/2 months ago, i disabled agps and am using com4 baud 9600 super fast gps now.

I can second or third... that.
Firstly, I don't mean to invalidate any previous comments, posts or fixes, or insult anyone's intelligence. I just merely report my VERY UNSCIENTIFIC findings.
I've had my ATT Fuze (HTC Touch Pro) for about 3 months now, and I've tested various GPS apps in the quest of finding out whether the hardware is the one to blame for the GPS POSITION LAG. I'd like to share my personal findings so that it may help others.
The ONLY GPS application that I can say that come very close to NOT having GPS POSITION LAG is Mobile Navigator 7.3.1 (build 137). On top of that, this version of Mobile Navigator is the only one so far to be ALMOST right on when the destination is reached. Other applications that I've tried always show the destination is 2 or 3 houses down the street.
The following applications I've tested all have position lag: one previous version of MN7, IGo8, TomTom 7, iGuidance, Garmin XT, and NDrive.
Did I use the registry tweak as suggested in previous post and did it resolve the lag?
Yes, I did try the tweak. But personally, I don't think it solved the problem.
Did I change to different ROM or Radio?
No. Everything on the phone is stock ATT Fuze.
So, is the hardware or HTC the one to blame for the lag?
Sorry! YOU have to come to the conclusion on this one.
I have a related problem, with the GPS device freezing (?) at high speed. I drove recently in Germany, and up to 120km/h my navigator (HTC-TP + Destinator 7) worked fine. When I drove faster it just stopped tracking, and resumed when I slowed down below 120km/h resumed.
Anyone experienced that or has an idea how to fix it?

TomTom7 also isnt working perfectly for me. It seems to be about 3-5 seconds too slow. It shows me at the street after I have already passed it. I made the registry setting changes that were posted earlier and will test the lag this afternoon ( it may be the Polling Interval being set to 1000 vs 100 i hope. I will report back to say if it has helped
Ok, I've moved from a Touch Pro to a ex-AT&T Fuze so that I could get 850Mhz band I needed on Telstra (Australia). It's all working awesomely thanks to the guys help here and after a diversion where I had to get my SIM card holder replaced.
Now the remaining glitch is that the GPS is totally unusable Which is a show stopper since I use it a lot. I had it in the car for a 2 hour drive, and it only found one or two satellites the whole time, and they were not strong enough to get a lock. Most of the time it showed zero. Sometimes I eventually get a lock, but it doesn't last.
By comparison the Touch Pro has no problem getting and keeping a GPS lock under the same circumstances (with the two units side by side). They are both running Tael's ROM and the same version of Tomtom. Google Maps has the same issues.
Two possibilities I can think of are:
1) The Fuze has a bad radio ROM and upgrading/downgrading might help
2) When the phone repair place replaced the SIM holder, they didn't connect the GPS aerial correctly - so I'll need to take it back
For #1, I'm a bit doubtful as it is reporting v1.14.25.35, protocol 52.64c.25.35U and this thread seems to rate the GPS reception as one of the best. Also can I put any Raphael radio ROM on the Fuze? Or do I need to find an 850Mhz AT&T one?
#2 is going to be awkward as I'll have to convince them they have done something wrong and get them to repair it free of charge. Can anyone tell me how likely this is? Has anyone pulled one of these units apart? Is the GPS aerial something that they may have just not plugged in?
Any other suggestions would be appreciated. (I'd be over the moon if there was a simple software fix. Anything else I should check? (I have updated QuickGPS with the latest data etc).
Thanks in advance!
I'd say run GPS Test while standing still and wait for a lock - I'm not sure what conditions you've tested in, but I've had experiences in the past with the Fuze (and a magellan) that if you were driving, the thing would take forever to get a lock if you didn't get a lock before moving.
Also; I'm running 1.14.25.05 - I ran .35 for a while, but reverted because NRG uses the .05 rilphone.dll; you could try that....
Thanks for the reply, but I've tried it standing still. Very occasionally I can get a lock, but it takes about 30 minutes, and doesn't seem to matter if I am moving or not. My Touch Pro is running a really old radio (10.x from memory) and it can lock and hold the satellites fine.
Has anyone pulled one of these things apart and can tell me what could be a hardware issue? Is the GPS aerial something which needs to be plugged into the mainboard for example?
Does your quick gps have the correct regional setting? Check HKLM/Software/HTC/QuickGPS. There is a value for region-I'm not sure if it updates automatically or not for your location. All I know is that my fuze's GPS sucked donkey balls in the UK. Normally, it just sucks French Poodle balls. I don't use A-GPS, so that wasn't the issue.
Hmm...ok. I had assumed that A-GPS was the technology, and QuickGPS was HTCs implementation. Are they different things?
Anyway, both the Fuze and the Touch Pro are running exactly the same ROMs (Tael's latest) with the same QuickGPS software and identical registry settings (but different Radio ROMs).
I just did a refresh of the QuickGPS data and put them side by side on my balcony for about 10 mins. Ran Tomtom with the GPS diag screen. Not a great view of the cloudy sky, but...
Touch Pro:
Shows a number of satellites, and finds reception from 3 or 4. The dots move around the compass a bit. Not as many detected initially (grey dots down the bottom of the screen is only about 10). Still can get a signal from one satellite sitting inside on my couch.
Fuze:
Full bottom row of grey dots, but didn't get any signal from a single satellite the whole time. Nothing. Also, the positions of the satellites on the compass seem to be in different places than the Touch Pro.
Re the region settings... the registry on both devices doesn't have this entry. There is a curRegion=dword:00000000, but no region at all. I'm wondering why this would be needed since the Touch Pro doesn't have it either and seems to work, but suggestions are welcome.
I notice there is no Services key either, like I found in some other posts. eg:
[HKEY_LOCAL_MACHINE\Services\QuickGPS]
"Keep"=dword:00000001
"Index"=dword:00000000
"Order"=dword:000000FF
"DisplayName"="QuickGPS app service"
"Description"="dll for icon in TodayScreen"
"Context"=dword:00000000
"Dll"="GPSAux.dll"

Again, the Touch Pro is working fine without this, but is this still needed in modern ROMs?
Still wondering if this is a hardware problem. Can anyone tell me how likely it is that the phone repair guys forgot to plug an aerial in or something?
Also, is there any better GPS diag software or is Tomtom the best bet?
Thanks.
A-GPS and QuickGPS are unrelated. A-GPS uses cell towers to help get a fix. If you've got the same roms on each device, I'd guess they're working the same. I think the gpsaux.dll service just warns you when the data expires, but I'm not 100% sure of that.
Try different radios; that's all I can suggest. The GPS on my fuze pretty much blows, so you're not alone.
Ok...how do I turn AGPS on again then?
By "pretty much blows" I assume you don't mean you can drive on an open freeway for 2 hours with clear skys and only faintly see one satellite the whole time do you?
I was kinda happy with the GPS on the Touch Pro even though it would sometimes take until the end of my street to get a lock.
Wonder if I should do a hard reset before taking it back to the repair shop... sigh.
You can turn A-GPS on with advanced config, and also enable logging, which will tell you if it's working or not. These are the keys for logging (I don't use it, so mine are blank).
Code:
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver]
"MaxLogFileSize"=dword:00000000
"OldLogFile"=""
"CurrentLogFile"=""
I think that A-GPS is HKLM\software\HTC\SUPL-AGPS\enabled=1, or something like that.
I used to get pretty good cold locks, like in less than 2 min reliably, but now it seems to take forever, as much as 30 min. It seems like my gps has gotten worse over time. Once it's locked, it works fine, though.
Ah yep - thanks. Advanced Config says "Assisted GPS = Yes". It's logging, but for some reason I can never open the log file (error, cannot be opened). The backup log file opens, but I'm not sure how to read it. About 4 lines with seemingly random text and lots of commas...
Ok, this is still not working...
I took it back to the repair place, who opened it up, did a visual inspection and told me there was nothing wrong with the hardware. They said it is a software problem (which it may be, but faaarked if I can work out what)
I have downloaded the HTC GPS Tool. I don't exactly know what the log data that it shows is, but I'm guessing since it seems to connect ok to COM4 that it is finding the GPS chip in my phone, just not getting anything useful as far as a signal goes.
Does anyone know how to read the logging data from this tool? I'm guessing that just because it is receiving data doesn't mean that it can see any satellites (since it performs just as well indoors)
Next I tried loading 'Raphael Radio 1.08.25.20M1' and the relevant Rilphone cab - when I read up about Rilphone cabs I started to wonder if that was the source of the problem, since I assume TEAL's ROM doesn't include the specific version for my radio. No luck though.
Next I put on the latest TEAL ROM, mainly just to set everything back to defaults in case I had screwed anything up. Updated the QuickGPS and then spent ages standing on the side of the road with my fingers crossed...
Nothing. Not a single satellite signal.
Any suggestions? Otherwise I'm going to have to buy a new phone. Should I keep trying different radio ROMs? Is there any way to check the hardware is actually ok?
I don't know if the microsoft gpsid.dll is included in the rom or not, but you could try switching from using the HTC intermediate driver (gpsidhtc.dll) to it. I've been using the gpsid.dll for a few weeks, and it's not worse, but may be better than the HTC one (tough to say, really).
These are the reg keys for gpsid.dll:
Code:
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID]
"Dll"="GPSID.dll"
"Order"=dword:10
"Keep"=dword:1
"Prefix"="GPD"
"Index"=dword:0
"Context"=dword:0
"Flags"=dword:2
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers]
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Multiplexer]
[HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Multiplexer\ActiveDevice]
"Dll"="GPSID.dll"
"Keep"=dword:1
"Flags"=dword:2
"Context"=dword:12344160
Here are the ones for the HTC driver:
Code:
[-HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID]
[-HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Drivers]
[-HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Multiplexer]
[-HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver\Multiplexer\ActiveDevice]
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\GPSID]
"Dll"="GPSID_HTC.dll"
"Order"=dword:100
"Keep"=dword:1
"Prefix"="GPD"
"Index"=dword:0
"Context"=dword:0
"IClass"="{A32942B7-920C-486b-B0E6-92A702A99B35}"
If you try it, do a full backup beforehand. I had trouble trying to get the HTC driver reloaded once. You may need a hard reset/restore.
Hi to everyone,
I recently obtained an i9003 (It was probably manufactured a year ago, however I dont know to check it). I'm very happy with everything but the GPS.
I know that it has been debated a lot, I read all guides on this forum and others, I followed this one:
http://forum.xda-developers.com/showthread.php?t=1069416&highlight=gps+improve
and then tried with this one:
http://forum.xda-developers.com/showthread.php?t=1032034&highlight=gps+improve
I even installed GPS Aids v2 (but my phone is not rooted!).
I tried this fix (the piece of paper to put pressure on the antenna):
http://forum.xda-developers.com/showthread.php?p=13133654#post13133654
Then I decided to open my device, and modify for the connection between the antenna and the board, like explained here for a similar device:
http://forum.xda-developers.com/showthread.php?t=878970
You cannot say that I didn't use the "search" button
So far these changes were not successful, at least the performance did not change perceptively.
Near the window, in a tall building (6 floors above) I don't get any satellite on view, on the balcony I get 3-4 at around 30dB (and I get a lock in with a very poor accuracy, like 300feet). Is it normal that the number of satellites is so low? I was wondering if the LTO file is the correct one, it is called north-america and I live in Europe... Is it normal?
Do you think that rooting my phone would help? I'm happy with the stock ROM so I would not like to root it just for fun.
Which additional info do you need to help me?
Thank you very much,
Michele
Its done and verified.
Root, Flash XXXKB3. Tats it.
20seconds max to get gps.
I evn use GPS Aids 2, LTO method. 15seconds...
U did use search bt u shld hv posted it to one of d already existing GPS threads....

Do you mean that you're confident that my issue is software?
Thank you man!
Michele
I also tried all the software fixes mentioned here and nothing worked so i flashed XXKB3 and now it locks instantly. Also, since you do get a lock, i doubt its a h/w problem.
Yea i tried evry damn possible settings at LbsTestMode and evrytn up on xda bt ntn worked.
Finally flashed.xxxkb3 and bang! Saw my location using GPS for d first time thn..

You will need root access for this.
Download faster fix from market
Change the server to your country and set the server
If you are in India, server should be in.pool.ntp.org
So you think that the issue is coming from this LTO file? I will try and flash XXKB3 when I receive my USB cable

I finally flashed XXKB3, re-installed gps aids and faster fix, but Im not sure it improved the performance. On sunny day 100% clear sky, near to my window, I get 4-5 satellites max in view, it locks and unlocks intermittently and accuracy is 50m...
I set LTO file to europe also. Maybe my building is particularly rich on concrete?
U gt 4-5 satellites frm inside d bldg? Tats insanely freakish. I get 0.
Use GPS Aids 2 and Download LTO file.
Wen i first flashed xxxkb3, d gps locked in 30secs max, bt a few days later it stpd workig all together.
Gps Aids2 and bang!
No sorry, I'm in the balcony with a good view on the sky. What I meant is that I'm next to the building wall!
Wait for sometime
First time might tak smtime

Getting 4-5 sats in a balcony is perfectly fine. Doesn't mean hardware problem. But getting a fix using only one view of the sky is difficult.
Gps fix needs 3 sats minimum to get a 2D fix (without altitude). But the sats need to be well spread to get quick fix. Accuracy of 50 mts is best u can hope on non-us-military devices regardless of whatever accuracy reported by software or others.
Try a location where sats hav about 90 degrees seperation or more. Remember just 3 good sats are enuff. Most of the time gps rejects data from other non-geometrically-optimul sats.
Let me know if this post is any help.

My question is what is the max number of satellites were you able to lock given all ideal conditions, for me the max was 4 (took 5 mins to reach this figure under open sky) on this phone while Xperia arc and HTC wildfire were able to lock 20 satellites from the same location. Is the GPS on phone really a piece of sh1t ? Just confirm this and I am prepared to sue Samsung in consumer court over this.
Adding to this, while traveling in a vehicle the other two phones (mentioned above) were showing realtime progress of the vehicle on the road, whereas Galaxy SL was highly inaccurate and even the wrong position shown was not updated constantly.
In stock condition of d phone, GPS is really a piece of sh1t....

gps fix
hello
I hope i am in the good discussion,i am not very confident with the forum.
I have now 2 i9003,ifound the gps was working like my stand alone garmin gps,taking sometime a long time to fix some time not ,depending of the time it was swithed of or where i was.Like a gps without Agps.
So what i did is:
go to setting with dialing on the phone *#* #3214789650#*#*
I did some test and now for me it's obvious that the operation mode in application should be "MS assisted" (stand alone means that it doesn't use at all the data network to help for the first fix)
accuracy should be put at 100 ,it doesn't means that it will be more or lest acurate,i understood that if the value is lower that this it give data to your application(sygic or other).If it goes over 100 you will get something that "waiting for valid signal"
There you can do some test like i did :
-put opération mode to "stand alone"
-go back and "delete gps data"(so no satellites history)
-get position test ,in that case it can take 15 min to get a fix depending where you live.
go back to setting:
-put operation mode to "ms assisted",so it use satellites and network for the fix
-go back and "delete gps data"
-get position test,in that case it take less than 2 min.
If it's not the case check :
-go in supl/cp settings ,check the serveur ,i don't know if we can put the same serveur all over the world but i think yes,for me it work well with the default one
supl.google.com port 7276 ,secure socket off,agps mode supl
-remember you need to enable data in android menu :wireless and network,mobile network,network connection enable (that a traduction of my french menu)
for info,i have the original rom xwkb1
I hope it helps.For me it was night and day,now it works as well as my desire which was very good.
I just forgot to mention one thing,if you switch data to wifi and go inside house through a router,i think agps cannot locate you with the network,so they can't send you data,not sure about that,but that's the way agps works.(so no wifi)
For the 1st time i use GPS in SL.. I waited for 10min or even more with the orignal server which set to north america.. And i tot the gps for phone is so always like that.. but when i see this forum gps fix.. i just "whoa".. i dont even know there is gps problem in my phone..
SO.. i str8 root it.. flashed to XXKB3..
gps fix set to Asia.ntp ( i from Malaysia)
and i try get sattelite signal from outside of my hse with clear sky..
LOL --> result : none.. get 3 satilite but didn't lockon even with my wifi switched on
and then i go download gps aids .. switched on my wifi download the LTP file.
and try get sattelite signal
Result: 10GPs in 10 second and lockon immediately
I open my papago.. lOL.. position fix..
I didn't touch anything on the SUPL setting or standalone or wat
I didn't even go open my phone and put aluminium foil
Just like that..
GPS fix.. I think the gps aids is to use for searching satelite signal and lock on your position.. so when u open up the papago.. it will str8 lock on your position without waiting 10min or more..
Haahah..
edmund~ u r right!
