[PROB] TouchPro GPS lag problems

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

I noticed GPS problems yesterday with Route66. Havent have time to test GPS lot before, just checked that it can find satellites and really works with Route66.
First while driving, Route66 got fix to satellite pretty quickly, but drop it then after couple seconds. Then couple secods of lag, again found satellites, couple seconds ok, drops again. This keeps going over no matter what, moving or staying stopped.
I then did soft-reset, no help. Then tried Google Maps with GPS, that worked no prob. After using Google Maps I returned to Route66 and strangely satellite fix was ok...
This might be just random satellite fix problem, but strange enough

Many of us have/had that issue so I can confirm you Its a device issue, not a satellite situation. The registry tweaks minimize that problem but I hope HTC solves the problem in his next driver/radio rom/... and the users hasnt to tweak their devices (95% of the users probably will never read this forum and they dont know how to "tweak" their devices

Thanks for sharing. I 'll check it.

Thank you!

I applied all the patches, my TP still doesn't want to find the sattelites...

F.....g hell!!! I tried anything,and morning I've got a fix with 5 satellites in 20secs,so it looks nice(yesterday evening I did the tweaks). But after 4 hours it can see 1-2 satellites,sometimes 3,very rarely 4 under blue sky. So 2 hours of my travelling from city-to-city I didn't get a fix! Co do pici s tym je!!??(sorry for slovak lng,but I cannot speak it english,because so wrong words english language doesn't have). I bought an useless technology and HTC is rolling on the floor laughing,how the customer is stupid. F..k them all with their technologies. Another thing is wifi...no comment is better. I will maybe buy an crazy Eten with Sirf3 and HTC with their stupid Qualcomm can go to hell. For what are all the technologies here,when they are working <20% of time? I am so angry on HTC,so when my kind of device will appear,I will immediately sell the Raph.

For those how have still problems
1. Hard reset
2. Applied the tweaks
3. Download last QuickGPS
4. Install TomTom
5. Have a little more patience...
Gook luck.

Did all that and the bloody phone is still not getting a fix on satellites...

I am confused in other way...
Why it does lock the satellites in 30seconds and it sees 8 sats.and few hours after it has problem with seeing 3 of them at the same place with same weather conditions? I believe,that tomorrow(when I will not needed to have the fix,anyway I will try it) will fix the satellites ASAP. Do the Raphael have a status-sensor,that knows,if I need it right now or not? That's my opinion,while it doesn't work,when I need it and works when I testing it...
I will s..t on whole GPS technology and I will trust the plain maps as before(unfortunately,that costs me some money/energy that I spend for that).

Totally amazing
This is just amazing. Thank you!
Now I get a fix in 10-15 seconds. Earlier it took several minutes... totally amazing...

tried this also and been driving around for almost an hour without results is that enough patience?

hmm, my gps was working normally, applied these patches and nothing changed..still working normally (no lags etc.)

Applied all the patches except one (I kept A-GPS on), and after testing with iGo it's working like a charm. With the latest QuickGPS data downloaded, it can still take - seconds to get a fix, but the positioning is accurate (no more 100-200m lag), the devices sees 4-6 satellites in the Belgian sky, and the navigation is finally usable on the Touch Pro. I'll make regular checks in the coming days and I'll report the results. Thanks for the tweaks!

With A-GPS enabled the GPS works great. I had it in my pocket with GPS tuner running while running in a forrest and he didn't lose my position and no lag. The problem: with A-GPS enabled TT7 loses the fix every second. Like 1 sec there is a fix, next there is not. And it keeps doing that. When I disable A-GPS it takes way longer to get a fix with TT7 but it holds the fix.
Tip: driving around makes it harder for the gps to get a fix.

Odd GPS issues

OK, so I've dug around the forums and have yet to really find anyone who had a similar issue and wasn't able to fix it with either FasterFix or GPSStatus so thought I'd start a new thread. If anyone knows this answer and knows it's in another thread then let me know and I'll shut this one down...
Anyways, the issue in a nutshell is that Maps refuses to work without "Wireless Networks" being checked (it throws up an error that tells me to turn on My Locations or to turn on either "Wireless Networks" or "GPS satellites" even though GPS sats is checked in the settings) and even then the accuracy is horrible (on tower-based, which is more or less to be expected since it's a triangulation, I believe), Navigation/Locations will both get a location but it appears to be "Wireless Network" based, GPSStatus shows a max of only 3/3 sats even outside on a clear day but no other app sees those even those 3 sats. I basically think my GPS chip is locked up. (Is that even possible?)
The GPS issues started one night on CoreDroid's V5.0 after working for quite some time on CD's various builds, including working on 5.0, so I flashed up to 5.1 and still no-go. Wiped everything, reflashed 5.1 and still nothing. Moved over to RCMixHD 5.9 and it still acts up. It used to be that I could uncheck "Wireless Networks" and it would just bounce off of the GPS sats but now nothing seems to see the chip. I've wiped everything, reflashed numerous times, flashed a new radio (the latest Mar leaked GB radio), gone inside, outside, around the house, around the town, etc etc etc, cleared the Maps cache, uninstalled/reinstalled Maps, reinstalled Locations several times, reset the GPS state with GPS Status, redownloaded the GPS data w/ GPS Status, changed out the gps.spade.so file in CoreDroid 5.0/1 with one from the Inspire Dev Forum (I think, may have been General) that modded files based off of FasterFix files that were supposed to fix the GPS if FasterFix doesnt (the files worked for a whole one test...then everything quit working right again) and I've reset the NTP to North America's server via FasterFix and STILL nothing. I'm getting rather frustrated at this point and any help would be appreciated. Thanks guys!

How about flashing back to stock Rom?
Sent from my calculator

What would the advantage be? I mean I've already flashed different ROMs and gotten the same issue so part of me doesn't care to flash another couple of times but another part of me wonders why it'd help any since it's just going to be overwritten when I flash back to RC or any other custom. Will flashing to stock somehow reset the GPS. I know flashing to stock is generally one of the first suggestions but I've always wondered how it actually helps. Guess I'm off to hunt down the stock on my computer while I wonder lol...thanks

Did you use RUU to get back to stock Rom and radio? RUU does more than just flash the Rom. It flashes the radio to stock. Only reason I'm saying this is cause someone else had Gps issues and when they went to stock unrooted, everything worked as it should.

Do a forum search for inspire RUU. Should come up.

Awesome, thanks. I was unaware that the Inspire had an RUU. Well, most RUU's I've run across have been packaged into a program like ODIN but I think I can do the RUU manually via ADB. Hopefully they have a program out, though. Think all my stock stuff has been done via ADB and the Hack Kit so I'll dig around for an all-in-one program. Thanks!

Sadness...no such luck even on RUU stock.

Just curious, what method did you use to do this?
Is this the same one you used?

I have been having similar GPS issues on my stock Inspire. After a long HTC customer service call, I was advised to do a factory reset on the phone. Voila, the problem appears to be solved. I now get 8 or 9 satellites and lock in about 30 seconds. Also, after this reset, my battery life is much better. So, I am not sure what bug I eliminated in the factory reset, but I accomplished something. What would affect both battery and GPS? I know this is not the same as for a rooted phone, but perhaps there is some connection. By the way, just what SNR do users with solid GPS performance get on GPS Test? I never get SNR over 25 on any satellite, whether indoors or out...

HtcOmega,
I helped another person with an inspire, so maybe it might work for you too, Try the link in my sig and see if replacing the gps.conf with one of mine may help you. It has been very successful so far, it might help with your dilema as well. And if your going to ask whats different about mine then fasterfix app, the answer is alot.
Let me know.

I was having the same issue as HtcOmega and decided check out your link. I must say that my GPS is working as it should now. Takes at most 30 seconds for a lock without the case on. I flashed the north america zip instead of choosing the north east version. Is there any reason why you wanted people to choose their specific region?

Primarily the reason is I broke up the USA into 6 regions and made a script for 62+ individual countries because I am not using the generic ntp servers from the pool, these are ntp servers specifically for that location, and by narrowing down the location and not using a general ntp it should make lock times faster. If you read the thread for the most part quick reading you will see that the NA script is made primarily for people who travel to many places frequently and do not want to keep changing scripts, as well as people in the common wealth countries would use the NA script.
I am currently testing out 1.2 with a handful of beta testers to see if the new script can be a little more consistent, there are new commands in the new script, which is phase one at least for the HD2 since the HD2 is a prt and lacks the support for true agps.

[Q] Weak GPS signal, long satellite search [SOLVED]

Problem solved. Fix: http://forum.xda-developers.com/showpost.php?p=25128818&postcount=15
-----
It is as the title says. Actually I am a huge fan of Endomondo app and running, skating activities, that's why this feature is very important for me.
I have a Desire S on MIUI 2.3.16 rom, flashed radios aswell. Usually it takes approximately 50 seconds to find satellites, sometimes it can't even find anything at all. It's so annoying! Had no problems on stock HTC rom.
So far I have tried this fix, but results are the same: http://forum.xda-developers.com/showthread.php?t=1493695
Any exits?

Try this thread instead - as it is for the Desire S;--

But read it fully first

Okay, I have tried this method.
First of all I started to managing how to replace that gps.conf (located in /system/etc) from custom one to original, but it does not allow me to copy & paste there. Nevermind...
Then I installed zip from sdcard via Clockwork Recovery. Switched off my Desire S and removed battery for 1 min, just by time, then assebled it back and switched on. Turned GPS on and entered for ex. Endomondo app, yes it really showed "GPS o.k" after 2 seconds of sattelite search!! Before it was those 50+ seconds. Well, I was happy and sure that everything went fine and now I have superfast GPS responce. But not so fast! I did a trip for few km's and the app counted no kilometers at all! Then I entered Google MAPS app and GPS could not be able to show my position. But at the same time GPS icon on notification bar was not blinking anymore saying that device is searching GPS sattelites. Why so?
Are my GPS settings ok? (my location is Europe, Latvia)
NTP server adress:
us.poo.ntp.org
SUPL server adress:
supl.google.com
SUPL server port:
7276
/HTC Desire S, MIUI rom 2.3.16

try the free application FASTER FIX that assisted me.

Faster Fix works for some people, but all it does is changes the one line in the gps.conf file to reflect the local NTP server for your region. My understanding is that makes very little difference in most situations, but some people certainly do gain from it.
The AGPS fix has seemed to be much better - it actually tunes the whole GPS setup. I used the "Google Specific No-SSL v3.1 build" and it made a massive difference to my GPS system. I also installed "GPS Status & Toolbox" from the market and use that to reset my AGPS data and then download AGPS data as well. This seems to need doing from time to time (I do it every day) just to keep it fully in sync.
Like most fixes, different people experience different results - but looking at the thread and the information that way seems to be the most reliable.
Also, if you use any form of AGPS fix then make sure you uninstall Faster Fix as it will attempt to overwrite the changes if you run it.

I also recommend Fasterfix download it via Market.

Hello gentlemans,
Looks like my HTC Desire S GPS has totally stopped working! Nothing helps, even flashing from MIUI or Cyanogenmod to Reaper etc. I have a feeling it might be a hardware problem, because I have faulty dropped it, not hard, but still. Does DS have GPS module flex cable? If yes, it might be loosen, if it really is there. Any ideas?

I think i have read somewhere on forum that GPS antenna is in top back plastic cover of DS (where the camera and flash are). It's connected via sliders like WiFi antenna on battery cover. If you dropped your pet "head first" it maybe loosen the contact...
Don't know if this helps you, but i wrote it anyways
Hope you fix it! Good luck!

Did you wipe everything before flashing? I had same problem with internet access with different ROMs until I made full wipe and now all works fine.

Search the older posts. I wrote once: the problem might be HW. Your GPS antenna contacts might be bad. If no SW fixes help you - look it up.

I have disassemble my phone. But maybe somebody could say me corectlly where GPS module/antena is located in HTC Desire S?

GUYS!!
I have just noticed that GPS signal improves a lot when I take back cover off. It even connects to satellite while with cover phone sees 2 satellites max and does not connects after multiple tryings.

Finally, GPS works great! I simple applied 2 layers of double side tape on contact to isolate it from back cover. Now everything works fine. Few months of managing and works great, I didn't notice such changes before.
Another contact stays for signal receiving.

Hey, that's a neat trick man... how'd you figure out which is the GPS antenna and which on is the mobile one? Kinda counter-intuitive right, that disconnecting the GPS antenna gets you a better satellite lock! HTC would be hiding their faces if they found out, LoL!!!

That's like that, thanks.
I used a wire to make connection by step with first and then with second contact. Then I noticed that by touching one of them mobile signal improves. Applying wire on GPS signal contact give almost no improvement. And it means that I should lock the unnecessary contact by method I described below.
I hope this somehow helps for similiar experience users.

Hey dude, I had exactly the very same GPS problem with my Desire S. The GPS antenna is right below the camera lens and definitely not where the battery lid is. Anyway, I used the tape stuff and it works. For the first time I have a stable GPS fix after few seconds, even without data connection, meaning pure GPS and not A-GPS. However, there is no way I can explain this. THIS IS INSANE!

They probably would be surprised a lot! It's hard to explain, but seems like there is some kind of interacting between transmitter and cover. And contacts there are not made just for look.

So all you have to do, is make sure that one pin can't make contact?
But why did they put it there?
That is very strange!

GPS really messed up

The problem I have is that sometimes GPS will not get a lock even after an hour or more. Other times it will lock on to 9 or 10 satellites in 3 or 4 seconds. I installed GPS status & tools and when I can't get a lock it shows all the satellites stacked one on top of the other located at the tip of the North arrow - I attached a screen shot to show what I'm talking about.
I tried putting the phone in airplane mode and rebooting and GPS seems to to work, but I'm still testing since the error is intermittent.
I was getting the error before upgrading to ICS 4.03 and thought the new software might correct the issue, but it's still there.

Try Faster Fix in the market. Make sure that the location you're in is set to the location that you live at.
I used to have issues where roms would have a European base and I would have to download the North America GPS config for it to work. Haven't had those issues since Gingerbread, but it's worth a shot.

I've tried faster fix in the past and all it does is modify the gps.conf file and I still had the issue. Since I still have the problem after updating to ICS 4.03 I'm beginning to think it's HW related. Just wonder if anyone else has seen this and what they did to correct the problem - new phone?

At this point, especially considering you had the issue before the update, its probably hardware related. You could open it up to see if there are any loose connections, but other than that I'm not sure.
Sorry about grammer, posted from phone.

try cleaning the contacts with rubbing alcohol and a qtip. also make sure the contacts are good as well.

[Q] The GPS is driving me nuts...

To begin with, I got my phone rooted with CM10 on it - I don't remember how well (or if at all) the GPS worked under that one, because I found it laggy as all crap. I went back to Gingerbread and have LOVED the increased responsiveness, but the GPS is now flaky as all-git-out.
Here is what I have tried:
Old baseband plus...
Eagle's Blood
CM7 7.2 "Stable"
CM7 7.2 Latest nightly (2013 march something, iirc)
I dropped it back to stock and let it update to the new baseband, then...
CM7.2 Latest nightly (ye gods that sounded awful. Oh, and the GPS didn't work.)
HellFire Phoenix reborn/reloaded/whatever the latest one was - I followed all of the "THIS ONE IS DEPRECATED, FOLLOW THIS LINK INSTEAD" links.
I have used the following kernels, more or less randomly, in addition to the ones that came wrapped into each ROM...
MazKrnl v1.0 rc2
Trinity T15
Trinity ELP
MazKrnl and ELP gave me sleeps of death in addition to the GPS not working.
Now, my first GPS lock after loading HFP (my latest ROM - and I am just trying T15 with it as I type this) took about five seconds and held solid. I was SO FREAKING HAPPY! But that was yesterday.
This morning, according to "GPS Toolbox" it can see anywhere from 9-11 satellites - and has a lock on all of them - but won't give me coordinates at all. This is true even after about 30 minutes sitting by a 7th-floor window.
IT'S MADDENING.
I've been googling. I tried messing with the GPS.CONF file, adding and replacing north-america ntp servers. I've tried downloading and re-downloading AGPS info from the GPS toolbox app. I flashed the "for_old_bb.zip" that I found somewhere - even though that's supposed to only affect audio - and GOOD LORD THAT WAS A MISTAKE, given that I'm now on the new bb. (The "new_baseband.zip" which is its alternative seems to have vanished utterly from the internet, sigh.) So yes, I'm down to grasping at straws.
Did I mention the maddening part?
I'm aiming to put together a for-real, once-and-for-all solution to the GPS issues here, because everywhere else it's 2-3 years old and nothing referenced anywhere has worked for me. I know this phone is a little long in the tooth, and dev has basically stopped, but am I really the only one still in this boat?
Thanks - seriously - for ANY help with this.

Update:
T15 kernel (?) caused a sleep of death over lunch.
Completely eliminating the GPS info (App "GPS Status & Toolbox" -> Settings -> Reset) and letting it sit with no internet access for oh, about an HOUR led to a post-reboot fix in a reasonable amount of time.
Oh, also I removed the "SUPL" info - per this post.
Of course, then my battery was wasted, so I'm recharging to test again later.
Honestly people - is this phone worth it? I only "upgraded" from my HTC Thunderbolt for the 4G - which, I admit, is nice when I'm not on wifi...

This phone has always had GPS issues.
The last baseband helped a bit, but it was never fully resolved.
I still use this phone, and still use the GPS on it nearly daily for tracking my hikes and bike rides.
My steps:
Run GPS Test.
If locked, great, done.
If not, wait about 10-15 seconds.
If it doesn't lock within that time, it will never lock without a reboot, no matter how long you wait.
Reboot.
Run GPS Test again.
<Repeat the above steps>
Generally I have noticed that 95% of the time, that a lock will happen after a reboot.
The other 5% of the time, you will have to reboot again.
The other annoyance for me is that during runtime, while you are using the GPS, it will just lose lock.
If that happens, you are toast. It will never come back without a reboot.
I don't even bother waiting, hoping it will come back.
As soon as it loses lock, I do a reboot.
On reboot, it generally locks right away again.
