GPS locking phone up

Drove home tonight and had to avoid an accident, turned on Tom Tom 7 and the phone locked up after a few minutes requiring a reset. Tried again, same thing happened.
Tried google maps, again same thing happened after a few minutes. This happened to anyone else? I have TouchFlow 3d installed (but same happened without it loaded). I was able to use TomTom for half an hour a few weeks ago with no issues.
Anyone else having an issue or know of a problem?

No, I am driving with bluetooth on and connected to my Parrot CK 3100 and Navigation with Navigon MN7. I can make and receive phone calls without problems while navigating. After the phone call the navigation is shown after a few seconds again and at the right place (not where the call started!).
Just as it should be...

This happened to me on Sunday when I was using Copilot 7. I then tried Google maps and it froze again. To solve this I reinstalled Copilot and this seems to have solved the problem.
Only reason I could think of is that I had just transfered the files across to a bigger sd card and thats why it kept freezing. Not sure how it was related to google maps as it was only the copilot files I had on the memory card.
All this could have effected GPS in some way but I'm not sure.
Hope this helps...

I noticed that if you don't connect to GPS via com4, but rather GPS Intermediate driver, this will hang.
What's the GPS setting of your Tom Tom?

TomTom just shows it as "Built-in GPS receiver". I think the COM4 is only for external GPS?

COM4 can be used for apps which don't realise that there is a built-in GPS. If TomTom is playing up it's worth trying it.

Tried COM4 setting but TomTom still locked up the phone after a few minutes(I'm in the office with poor GPS visibiliy also). Soft rebooted and tried Google maps which wouldn't recognise COM4 so went back to normal setting. Google maps then continued to work with no issues this time. I hadn't yet loaded TouchFlo 3D panel. Could this be a resources issue, is just having Touchflo installed a likely culprit? I haven't made any "tweaks" to performance/memory, was also thinking of installing the custom rom (itje?) with TouchFlo included as I hear it runs better than installing the cab?

gps problems
I have had gps working perfectly with copilot 7 in fact been amazed how fast the lock is etc but now it has stopped worling altogether for no apparent reason. No hang ups or freezes just not getting a lock at all on either copilot or google maps. I have even tried a hard reset and reinstalled everything and despite wandering about outdoors for ages, still nothing. Anyone got any ideas before I have to send my phone back? Thanks.

same problem here, tomtom 7.4 and 7.9 hangs the phone. If i don't activate intermediate driver ("manage gps automatically", I suppose) tomtom can't find gps receiver
also, it isn't a tomtom problem because demo mode withot receiver goes very well (tested 1 night while sellping, no hangs)

Are you using XperiaTweak and changing the graphics and system cache values I had the same problem with tt7 after changing system cache too high, if you are try lowering system cache value.

also, no tweak, so it isn' graphic related. It's a gps driver issue. ****

although i don't use tomtom, this is consistent with my observation that using intermediate driver will hang the phone (I use Garmin MXT)
did you try using com4 instead? it should work.

hard reset seems to fix the issue... have to test more before declare it definely solved but now seems to work (30 min without freeze...) I pray

have you ever used Advance Config to enable Quick GPS? I noticed that might have created compatibility issue. Couldn't prove it though.

hell I don't think I've seen the GPS get a lock once... on google maps it always had "searching for satellites (0)" and it never increased. I usually found what I was looking for and closed the app by then. I installed Advanced Config 3.3 and saw that it said A-GPS was disabled, so I enabled it and made sure QuickGPS was updated with info and tried google maps again. Still... it can't find any satellites. My HTC touch diamond would get a lock in seconds on the stock ROM, even indoors. I think SE really dropped the ball with the X1 =\

as I mentioned earlier, I observed that my GPS reception/fix is more stable if I do not enable A-GPS via the Advanced Config method, but just download the data from the program.
now I can even get fix indoor or my underground carpark (not totally covered so signal reception is still possible)!

I had this problem for the first time today.
Both iGO and Tomtom would freeze after a few minutes requiring the battery to be removed to gain control of the device again. I did a hard reset only a couple of days ago so it should be relatively clean.
Eventually I found that downloading the latest QuickGPS file appears to have solved the problem (even though the previous one still had 5 days to run). I wonder if the QuickGPS file was corrupt?
Does the system use QuickGPS only once when starting up the GPS, or does it continue to consult with it during navigation? My experience suggests the latter, or it may just be coincidence...

First, make sure you test w/ nothing being install to make sure no other conflict.
I've been using Igudiance4(w/ GPS gate), Igo8, Garmin Mobile XT 5.020 (TomTom 7 not tested because it's suck compare to others) more than an hour (Los Angeles to San Diego) without issue (and I am using CorePlayer to play music in the background too).

I have nailed down the issue to the GPS setting applied by the Advanced Config Tool (ACT). Will probably have to go deeper to understand the registry value it sets so that I can simulate the same w/o the ACT to prove/conclude the point.
But before I undo the setting by ACT, I frequently have drop GPS signal (Garmin will always complain lost satellite, takes a few minute to acquire before losing the satellite signal again). If I switched to GPS Intermediate driver, instead of COM4, I would get the hung situation.
After I have undone the ACT's GPS setting, my Xperia now has NO drop signal, nor will it hang when I access the GPS through the GPS intermediate driver port, instead of physical com 4.

I am having the same problem again now after I updated the QuickGPS yesterday. And I can confirm this is not related to bluetooth or xperiatweak or TouchFlo 3D or intermediate driver or the navigation softwares.
This is the problem:
Start Igo8 -> GPS gets coordinates -> working fine for 2-3 minutes -> THE PHONE FREEZES
Start Tomtom 7 -> GPS gets coordinates -> working fine for 2-3 minutes -> THE PHONE FREEZES
Basically, after using the GPS for like 2 - 3 minutes, the phone crashed and needed to be soft-reset. I think running the QuickGPS caused the problem. I had the same problem last time I updated the quickGPS. But after like a week the freeze problem had gone. Since then I had not updated the QuickGPS for a long time until yesterday and my igo8 and tomtom had been working fine last week without any freezes.

GPS

I cant seem to get my GPS working all the time. I've got some Freecaddie software but the GPS seems to work when it wants. What do I need to do to get it to work everytime I use the software?????

It should work out of the box, and works very well.
For the first fix though, stand under open sky for a while.

Are you using the GPS indoor? Getting a fix indoor is quite difficult and not possible in most cases until you are not standing next to a window.

i have a similar problem, i´m using igo on my hd and it worked very good in the beginning, but since a while when i start it, it gets a normal gps fix but then the gps connection only lasts a few seconds (5-6) and then looses connection for about 30 secs and when it finally finds it again it lasts again only 5-6secs...
can anyone help me? it´s very annoiying when i´m in a foreign town where i don´t have a good orientation and my navi system won´t help me at all

Hmmmmm - this should work "out of the box" whenever you use a GPS application.
Try this free app: Chartcross GPS Test 1.04 http://www.chartcross.co.uk
It will scan for a GPS device if you have one (as HD does).

that´s not my problem, igo finds my gps receiver...

GPS signal dissapears for 30 seconds then re-appears.
This is resolved by a soft reset, although in one case (When I actually was lost) it took 6 consecutive soft resets to finally start working whereas normally it only takes one or two...
I would be very interested to hear if anyone has a resolution to this issue?? or any idea's what may cause it not to work properly before one or two soft resets??

mine kept stopping for 30 seconds while I was driving, soft reset is a bit of a pain.. does QuickGPS help ?

Definitely, having QuickGPS updated won't hurt. Some people says it doesn't help much, but it should. It downloads updated data from satellites so that the internal GPS does not need to wait for that info. Anyway, GPS worked for me out of the box, without QuickGPS; it does the work very well and is quick fixing the position. Try GPS Test, as said above.

I have Duffy's 1.7 ROM (and admittidly this issue has only started since I loaded this ROM, Quick GPS is on, but shouldn't affect anything ONCE the satalites are locked... what happens is the satalites pick up for 30 seconds then off for 30 seconds then on then off ad infinitum. I use Tom Tom 7 and CheckPOInt, other than that fairly standard apps... core player etc. At the mo I'm just in the habit of soft reseting before starting GPS, from a soft reset button in touchflo programs its not so bad. Anyone else experiencing this exact thing of 30 on and 30 off??

The problem of losing GPS regularly happens if you have assisted GPS active. Uncheck this and all will work fine.

Does it still lock on fairly quick without Agps? I must admit I have not tried yet.
I have a problem where I've tried TomTom7 and in the GPS status screen it shows up to 7 or 8 satellites really quickly (maybe 10 seconds) then they all disappear a few seconds later, and it says something like "Are you sure you aren't inside a building?" (yes, I just didn't notice obviously!), then a few seconds later they all appear again & then off & on etc.
It's annoying but when they are showing they give a relevant position and speed.
Is this the same problem? No-one knows what is causing it I assume?

Crett, ( and a bunch of you above) sounds like you have AGPS enabled. AGPS (assisted GPS) must be disabled or it will do exactly what you are describing.

Cheers, and yes, I have got Agps activated. But it doesn't explain why it happens though.
Does the gps still work well without the download assistance?

It works flawlessly without AGPS and from what I remember (not 100% on this) , the AGPS is a bug through all HDs (drivers prolly) might even be throughout other htc phones

as i understood it, if your cellphone provider does not submit a proper agps signal, the htc always resets the gps with the faulty data. so switch of agps.

how do I disable agps??
cheers

Start, Settings, System, AGPS Settings, Disable.
And yes, it's working fine with it disabled.
Thanks

hmm haven't heard that but good to know. Now is the problem that htc coded it wrong (waiting for a wrong signal that doesn't come?)? That would be my take on it, since i haven't heard of anyone having the agps working (otherwise I'd think it would be the cell companies fault).

not sure if this helps, but i was just pratting around with settings in tomtom as mine was loosing signal every 30secondstoo. changed to max baud rate on com 4 and its now working sweet as

GPS not locking satelites

Hello. I own a HTC HD 2 and my GPS seems to be malfunctioning.
I am trying to search for sattelites and it doesn't find anything.
I tried GPS test and Igo, nothing works.
Tested outside.
What should i do ?

I had a similar problem with my HTC Diamond. Try Turning off, take the battery out for 5 mins then turn back on. It worked for me.

It is not working for me

Try to get out of the house

right .. hd2 have one of the best gps receiver... igo8 for me is working faster than my ex-tomtom 520.. i think kpyhere needs to change his sys.txt and delete the content of the save folder ... do a search, under the thread of apps will find some good sys
PS - i never used QuickGPS, not even after a flash of a new rom

I got outside, staid there for a couple of cigarettes, but the gps was not locking to the satelites.
Tried GPS test. This doesn't want to work either...

Maybe a Fix for GPS not finding Satelites
I had the same problem, I tried all the suggestions in this thread and even from the entire forum.
I finally decided to turn AGPS off and amazingly, IGO8 and TOMTOM now find Satelites within 10 seconds. My thinking about this, is that AGPS is trying to find a lock using Cell towers first and this is causing the delay.
Anyway, my two cents worth and maybe it will help.

I'm just using the stock ROM on TMOUSA, but I get a lock on a cold start in about 10 seconds. It is so much better than the Touch Pro 1 or 2.

where do you turn off the AGPS? Thanks a lot!

I would like an answer to that question too.
Seems to be working with this one

So, no solution to this.

If you go to Settings, then to Location, it should be there or you could use the tweaks program in the previous post.

Update
I have just arrived in New Zealand (Auckland), started up iGO8 and within 10 seconds I have a lock on 5 satelites. Still have AGPS turned off.
When I get back home (Melbourne), I will turn on AGPS and report back how long it takes to find lock.

I have no AGPS setting in Location from Settings.
Can it be found elsewhere without using a tweaking program?

Here's how to get te best from this cute app
I found here http://htcpassion.wordpress.com/2008...indows-mobile/ a procedure that allows to get ULTRA FAST GPS FIX. I tried it and seems to work! I'm really astonished. Note: all benefits will be lost if device is switched off or battery is removed.
Let me translate the procedure and add some personal details for non italian mates:
1. Download and install .cab file.
2. Start application and set port (my Artemis default is COM4) and baud rate (my setting is 4800 but 56000 works too).
3. Place your device in a good position for gps fix (open air possibly, not under trees, not close to tall walls,buildings..).
4. Click Open and wait 10 sec.
5. Choose Clear Memory from the scroll-down menu.
6. Click Nav. Init.
7. Wait at least 5 min.
8. Click Close and wait 10 sec.
9. Close application, turn off the device and remove battery.
10. Wait 10 min.
11. Put battery back on, restart device, start HTC GPS TOOL.
12. Check the correct port and baud rate.
13. Click Open and wait 10 sec.
14. Choose Warm Start from the scroll-down menu.
15. Click Nav. Init.
16. Be patient (can take up to 10 min.), relax watching the Satellite Tab and wait for a fix (satellites will turn to green and you'll hear a beep).
17. Click Close and wait 10 sec.
18. Soft-reset your device.
19. Start your favourite GPS application and enjoy LIGHTSPEED FIX!!
Thanks&Greetings to fAnThaMaN.
Feedback will be appreciated aswell as an explanation of what really this procedure does to improve GPS performance so much..if anyone has suggestions..As far as i can understand it clears GPS memory and sets a Warm start..Anyway all the above mentionned waiting times of the procedure (except step 16...) can be drastically reduced if your time is gold

I am now back home, turned on AGPS and iGO8 and all my other GPS related apps do not get any satellite locks, I left iGO8 running for 30 minutes and still no locks.
I turned off AGPS and iGO8 found them within 10 seconds.
For me this is working. It maybe worth a try.

Still having problems with the gps...
Seems that i can;t get it working

I had similar problem with Asus A696. One day, it saw satellites (red bars in iGo or proper GPS receiver on in GPSTest), but without positioning.
It was dead amplifier (unfortunately) so if nothing else will help, I'd send it to HTC back...

HD2 GPS issue: failed to send nmea command????

I cant get my GPS to fix. I used HTCGPSTool and it came up with
failed to send nmea command
my GPS is set to COM4, all the usual settings...
Anyone know what this means?

After upgrading the ROM to 3.14 I am also getting issues with GPS.
The GPS gets hang after using for just 5-10 mins. The HD2 restarts and then doesn't work.
This happens even I am using Google Maps or other navigation software.
Sometimes HD2 doesn't found any GPS satelites also. Even I restart, no GPS gets found.
All settings are default and I haven't done any changes to the phone GPS settings.

Does anyone have solution for this problem?
Thx

Hi every one
I've got the same problem updated to 3.14 and Hd2 heats up a lot i know that from battclock software which monitors temperature and cpu% and device it self on lower part is getting very hot after that happen Hd2 restarts on and on.....
I've found that if battery is above 30 celsuis internal gps stop working and the only way to get it back is lover the temperature which is hard when you're driving
I've also got an bluetooth gps and works perfect no problems with this device maybe there is a problem with rom what do you think???
BTW I'm just downgrading Rom will post info is there any difference

GPS issue - satellites in use, but no position

Hi everybody.
I have SM-N9005 phone, currently running Temasek V16.0.
My GPS usually works fine, however sometimes it finds the satellites and uses them but doesn't get GPS fix for a long time (actually - never, as far as my patience go, which was about 15 minutes). After rebooting the phone the GPS fix is almost instant, with no problem.
So, what can cause GPS to be unable to get a fix, while it can use the satellites. Seems to be software related as reboot makes it fine. It is not ROM related, cause I've had it on stock as well as custom ROMs. Anybody can think of a fix that doesn't require me to reboot?

No, I have given up on GPS of this phone, Snapdragon variant. As you said, rebooting the phone makes the GPS lock fast/ instant, but for normal usage sometimes GPS just won't lock. All I can gather from my personal experience is its about Assisted GPS. When you are restarting your phone the AGPS data is being downloaded automatically, that is how Android works anyway, and that's probably why the phone gets a super fast lock after a reboot. Use app like GPS Status or something to have the phone download AGPS data at short interval, see if that helps in anything or not.
However I have never had any problems when I am outside, the GPS locks within 30-45 seconds no matter what, its the inside problems which used to bug me, but as I said, I have given up.

Hm, I've never seen such a problem. I use my N9005 for travelling across Europe quite often, and it usually locks within 10 seconds to 2 minutes, depending on the location and the number of satellites.
Aside from the occasional glitch, of course. Like going backwards or sideways. :silly:
And it seems to think I'm somewhere off the coast of Norway right now. That one creeps me out quite a bit...
The thing is that when you reboot, it uses all available connections to pinpoint your location. Including your mobile data. (And WiFi if available.) So if you turn on location services right after rebooting, your approximate location is still in the cache.
Triangulation Over Data works within seconds, as opposed to the time required to lock on to the satellites in orbit when it is only allowed to use GPS. If you turn on the higher location modes, it locks much quicker. You can turn it back to GPS once your location has been established.

I am talking about GPS only. I use GPS Status app for a long long time (with my previous Android devices as well), so I can monitor the GPS fix. After reboot I get GPS position almost instant or sometimes I need to go into GPS status app and re-download A-GPS data (which is max 1h old, because of my settings) and then I get my fix.
When my problem occurs NOTHING (short from reboot) can get it to get a fix. I tried deleting and downloading A-GPS data, turning location on and off and from high precision to power saving - it just won't work. Of course I'll get postition from WiFi or cell towers, but GPS just won't fix, even with 12 satellites in use, after waiting over 15 minutes (which should be more then enough, cause whole GPS almanach is transmitted over 12,5 minutes and I get it from A-GPS anyway).

I would start by wiping the phone installing stock rom and testing . Still a problem then its hardware .
