problem with gps - Desire HD General

after my phone update to 2.2.1
i can't seem to connect to the gps
The navigation application is always "searching for GPS"
sorry for my english

No need to apologise, your English is perfectly understandable.
How long has it been searching for a fix?
Usually your GPS has to download a file called an "almanac" which tells your gps chip where satellites will be at certain times. This can be a slow process and is only done once as your phone will keep it updated thereafter.
Your phone should use your data connection to speed this process up (A-GPS).

about 15min still can't connect...

It usually doesn't take that long. Are you outside?

at home

Your GPS fix would normally take a lot longer if your not outside. Stick it on a window sill/ledge for a bit. Or sit outside.

Lucky guy, i almost all the time w8 while GPS fix (even when the sky are blue and sun is shining) and even when 10 and more satellites are available, for 1-2 mins . Yeah, it's not a long time but when i'm driving or even walking i need it to be done in second not minutes... I have a device to compare with that's why I'm so critical in this question... Almost forgot... the device is iPhone 4.... I hate iphone after he is beating my GPS like a boy..

GPS problems numerous. Sticky?

I propose that one of these GPS problem threads be made sticky since we cannot simply search "GPS" here and the GPS problems seem to be accumulating.
With that said, I would have to say that my GPS performance is pretty terrible. At first, it felt like doing the QuickGPS thing and/or deleting the xtra.bin file helped. For the most part, though, getting a lock has proven quite sporadic. What should the expectation here be? Should I expect the GPS to work reliably indoors? What about if I am near a window? Why would it work in some buildings near a window and not in others?
My personal opinion is that the GPS should work within 15-20 feet of a window. Using Chartcross GPS Test, even when the GPS is locked, I am getting mostly yellow bars. I am not exactly sure what a good reading looks like on Chartcross, but there appears to be a 25%, 50%, 75%, and 100% bar. Maybe the 25% bar is 100%? In any event, I rarely have a satellite that is getting above what I suspect to be 30%.
Is there a thread somewhere that details what the various fields mean and/or should read in Chartcross or a similar utility? I am coming up on my 30 days to return the phone, so if someone thinks that my device may be defective please speak up!
Thanks as always XDA-ers!
GPS signals are not strong, you have to be near a window (e.g. less than 50cm) or outside to get it to work properly. Inside I get 8 sats with too little to lock, outside I can get up to 11 locked. I use modified GPS settings to improve the lock. I've created a CAB for you.

Try them and then tell me how it works.
No you cant use it inside, but this has nothing to do with windows. Think of it this way:
To use the GPS, you need a line of sight to the sky, small barriers it will work through (like car roofs). So even a "line of sight" to a window, wont help you because of the thikness of the house roof. To be able to use GPS inside, you need something else, like a big antenna
Anyways, the GPS is for outside/car use only.

That is partially true. The signal can "reflect" off surfaces as well, though - as with light - weaker. And it does have to do with windows simply because a window has a lot (lot!) less density than say, a brick wall. Less density means easier path for the signal. Being near a window does indeed increase the chance of signal lock.

hah, I did not know that! Thanks for informing me
I have a lock when I am inside all the time, usually about 5 satellites or so... out side that jumps considerably, in fact I was very impressed with the speed and sensitivity when compared to my Kaiser/TyTN II/MDA Vario III and I havent used quick gps yet... of course now I said that its going to be sods luck and it will [email protected] out on me...

Well, it depends on several factors. If your home is made of wood instead of brick, that'll make a difference. If you live higher above sea level, it might make a difference. If you live on the countryside, that will definitely make a difference. I happen to live below sea level in a brick house in the middle of an average sized city. My reception won't be something to write home about

I've only had signal ONCE so far with my X1
It was at my living room window.
After that, no signal, ever. Not even out doors.
Im in NYC, plenty of buildings, but cmon somethings gotta be wrong. I even tried a hard reset to get it to work again. Nope... Bastard GPS ):

Run quickGPS and install my cab. Try again and let us know!
Nippero:
you wont get any signal (or good accurate location) if you are in a big city.... your best bet is using google map w/ agps and let the cell tower locate where you are at
another thing I want to point out.... I tried using the gps on x1 when I was on the plane... while it was always able to lock on to a couple sats... it wasnt able to locate where I was at .... and the worst part is after I get back on the ground... the gps stop working and I had to hard reset my phone .... I tested it twice and both seems to be the case... so if you dont want to hard reset your phone.... I suggest you not to try it next time when you are on the plane
You guys must have really big houses to need GPS to work indoors

I really appreciate the quick reply and cab file. I will load it shortly. Is my understanding correct that A-GPS is turned off by default? If so, does this cab enable it? What improvement did you see with your cab file? Lastly, do you use Chartcross GPS test? I'm trying to figure out what the different fields/values mean in it.
Thanks!
Careful with changing the A-GPS to on by default. You can do this through Schapman's advanced configuration tool too, but I've had nothing but bad luck with it.
I use iGO8 and after I turned A-GPS on, the gps signal would drop every few seconds and would have a hard time finding satellites. Switching everything back to factory "defaults" and just using quickgps updates, I've had zero issues. Apart from the initial sat discovery, it's always fast to start and fast to pick back up (maybe 2-3 seconds) again.

Speaking of iGO8, does 8.1 work with the Xperia or only 8.3?

GPS is only able to keep a lock under a certain speed. Airplanes are fast, so you will lose the lock. Once on the ground you can get a lock again by running QuickGPS. As your location has changed tremendously (depends on how far you fly ofc), the sattelites aren't where your phone thinks they are.

You're welcome. My CAB does not enable aGPS, as it sometimes causes problems like quoted below. It changes some registry settings that basically tell your phone to keep looking for a better lock, for a longer period of time.

Do not that your individual experience with aGPS doesn't generalize to everyone. I've personally tried aGPS here. It made 0 difference (as far as I could tell), so turned it off again.
If you wish to try aGPS, feel free to do so, as it can be disabled as easily as it can be enabled, a hard-reset should not be neccesary.

are you on a vibrant or galaxy s?
Go to
Setting>check use wireless networks and gps. Download update for google maps and you good to go. Also install speech synthesis. Btw this is on the vibrant.
My gps works good and fast as soon as i click google maps for the first time it knew my exact address
guys thank for ur replies ..i have the Vibrant & the GPS is working now... i did nothing to it ..but i am happy also be looking out for my wallpapers coming tonight for the VIbrant
I'm having problems with the GPS.
I have two G1s and got two Vibrants to replace them.
The G1s CPS lock easily and give you 12 feet precision very fast.
The two Vibrants take forever to lock and stay at 35 feet precision, sometimes going down to 30 feet.
G1s are miles ahead in the GPS department.
I'm dissapointed.
^ I'm not seeing those results and my Vibrant locks in quicker.
If you're going to compare it to another phone, then clear all of the google map cache before you start comparing.
My G1 and Vibrant took about 1 minute to fully lock on into my location and both were accurate. Sometimes the G1 is slower though.
Yeah maybr Cellular Data enables A-GPS instead of regular GPS. Not sure but now I get a lock in my house! Phones always suck without AGPS. 10 minutes to acquire a signal without it.
my gps has been snappy... interesting that there have been problems (compass has a slight jitter... but its almost imperceptible)
Nevermind Think I got it
i have yet to have GoogleMaps successfully find my location, both inside my apt and standing outside. My GoogleMaps updated itself this morning. Any tips?
Have you enabled cellular networks for location services?

This shouldn't be necessary. I know aGPS helps, but pure GPS should work anyway, albeit taking more time to lock.
I bought two Vibrants and left hem out in the backyard for 1 hour, over a table, and they could not lock on the satellites. One hour!
The GPS ship in these unites are either second class or there is a bad batch.
The old G1 locked in 15 seconds.

sadly, i did not. I'm very very new to android and didnt know something like that wouldnt be on. That certainly did the trick, thanks!
P.S. anybody put in the gps test code and play around with skyhook? i just turned it on. In addition anybody know what changes the accuracy value does (default is 50)?

15 seconds without aGPS is better than a standalone GPS system. You must've had aGPS on..
@jblade1000 Yeah I didn't even think to check it. I think it was left off unintentionally by T-Mobile or Samsung. It works for me. We might not even have standalone GPS. It's not out of the question.
My GPS won't lock for the life of me. Thought it might be due to being inside, but I went out in the middle of a field and got no lock.

GPS UK

right I have to know if its only me but even after editing the gps config file it still only works every now and then and even that requires gps status and tools? At the moment using WP7 and gps is lightning fast (fix etc) but switching back to android as android is most definatly superior in most cases at the moment. Especially the camera quality is bad and battery life is ok but better on android
Is there a rom with a WORKING gps not one that works under supervision? as I like to use the gps apps like maps and copilot etc
OK well just changed a couple things and now gps is working
I dont know whether Radio revision affects it but downgraded it to 2.12 from 2.15 and left my gps location as europe after clean flash and now getting a gps fix under 10 secs mass improvement to before (2 mins to never)
might try with UK ntp.pool settings, and see the results
Edit as you like, but < 10 seconds is about as good as it gets, don't fixit if it ain't broke!
well tried it anyways and it is even better >5 seconds is this a radio related. If so gotta write down this radio version for future reference
You get quicker fixes when you've already recently had one, I don't think a <5 seconds cold fix is possible.

This is intresting.
Is it possible to keep us updated in a couple of days to check if the quick fix is consistant with radio 2.12 ?
I think it would interest alot of people.
My phone was also with 2.15 previously, as willzrocking i experienced mixed result with this radio and long time locks in any case.
This morning i was encouraged by this post and gave 2.12 a try, unfortunately for me it seems tobe no go, it seems worst than 2.15 on my phone.
In the same road to my office (10 minutes by car) 2.15 was able to lock 1 or 2 minutes before i reached destination (not really usefull...), 2.12 was not able to catch the signal.
I'm going to try have a lock in a plain surface later on today and will let you know the results.
Cheers.
Still working good for me... I am using the Cleandroid Rom but even though the gps is now very good the network keeps dropping alot and sometimes randomly the H signal disappears and replaced with G sometimes until I switch between flight mode so think I am gonna have to sacrafice the GPS until I find a better radio/rom
I've just put on 2.12 here in the UK and don't notice any real difference at all
EDIT: ooh think i've now solved it for me!
I also have an Orange San francisco ( ZTE BLADE) and that always locks on GPS very quickly...
so i had a delve into the blade's gps conf and i notice a few parts were commented out that arent for my HD2.
the parts i just added/commented out are.
I added
INTERMEDIATE_POS=0
and commented out the following to look like this
#SUPL_HOST=supl.google.com
#SUPL_PORT=7276
Now after locking/unlocking the phone and rebooting i get a lock onto GPS in under 10 seconds every time, whereas before it was very hit or miss!
Out of curiosity, those who have problems, how many have the app GPS STATUS installed? i'm wondering if it is causing a problem too.
this thing is driving me crazy... as the gps is!
2.12 was worst than 2.15, then i tried 2.08, same as 2.12. So i did a roll-back to 2.15 and tried to put crunchie's settings into my gps conf.
Didn't notice any difference so i tried to remove gps status.
After reboot i made the following test:
launching google navigator 3 times, every time i placed the phone in the same position where i was sure to get good signals.
Between each tentative i removed the phone from its position, closed navigator, turned off and then on the gps, replaced the phone back.
It took 20 secs to do this operation.
I got a fix each time, which is good, but look at locktimes...
1) around 90" (good)
2) around 3 minutes...
3) around 4 minutes...
It seems like it doesn't save gps data previously scanned, every time it's like a cold start...
I really don't know if there is any way to fix this at the moment but i would really like to know which is the difference between my phone and yours. Maybe 'cause mine is brand new? (i received it the 4th of jan)
Very important for me too. So my parts:
RADIO: 2.15.50.14
ROM: MDJ's CyanogenMod 7 v. 2.6
COUNTRY: Latvia (EUROPE)
Actually this is the only Android build where I got any week GPS signal. Previously - nothing.
Well, on WM 6.5 GPS works extremely good and stable with the same radio.
I am using GPS Status (to download some A-GPS data, which really does not helps).
I live in Latvia, but my gps.conf was set to europe.pool.ntp.org. I was able to get some week connection today with a fix in approx. 10 minutes. When I changed my gps.conf to my country: lv.pool.ntp.org GPS stopped working. Will try now to revert back.
P.S. My friend with Desire HD also living in Latvia has north-america.pool.ntp.org, but still gets fix in about 30 sec. And changing gps.conf and downloading A-GPS data does not help at all.

That sounds promising, so I've edited my gps.conf to match and I'll get back and let you know how I get on with it.
Incidentally, I used Navigator today for the first time in ages and didn't expect it to work as I flashed a new ROM over the weekend, but it worked a treat. I'm in the UK but it was set to use a North American NTP server, so I'm surprised it worked!
Glad it did though

This 10 sec. story was only once. Now I again can't accure sattelites. Will try to launch with gps.conf file fully empty. Will see, what it does.
Mine seems pretty stable now, but gps status seems to screw it up so for those still trying I'd advise you don't open gps status at all and/or force close it

I'll bear that in mind - thanks. I don't tend to use any extra apps anyway. We all know from WM days that the GPS in our phones is pretty good without it.
I'll try it tomorrow, when I drive a mile down the road to my local shop. And yes, I do know the way

Do you mean program GPS Status? Well, I'm using it to find a sattelites and then quickly switching to Google Maps. )))
Why do you think it can mess up the GPS reception? I'll try not to use that. Thank's.

When I open it to see what satellites are connected then go back to maps, maps is no longer as accurate even though gps status says it's locked.
It looks like it makes maps revert back to wifi or gsm triangulation.
Then if I go back to gps status, force close it then reopen it, gps status is no longer able to lock on nor Is maps.
So, I open maps, leave it for upto 20 seconds (usually under 10) it locks on to 2M accuracy
If I then open GPS Status, it says no satellites.
Exit back to maps and I'm no longer locked on and it doesn't seem to lock on again (cold start maybe.)
Then , force close gps status
Force close maps.
Reopen maps and I'm locked on again after a 'cold start' and then maps behaves itself again with under 5-10 second locks even after reboots and gps off/on

Oh, well, thank's. I experienced it today on a road, that after GPS Status, my Google Maps were jumping from GPS sattelites to Mobile Network Stations.

Actually not having anything with t-mobile, but I still managed to connect... after a while, after a long while....

[Q] GPS problems

My GPS drives me nuts ... the signal is weak even outdoors on a sunny day. GPS Test shows maximum levels of around 25 on the street and even less on the balcony.
From the reports and Youtube videos I saw, the TF should do better than this, instead of constantly loosing GPS signal, shouldn't it?
Btw, I tried all available settings.
Might my TF be faulty?
PS: Is it normal, that the TF has less GPS problems in the late evening?
I haven't been all that happy with the GPS performance either. I haven't managed to get a lock when starting from a cold start at all, it sits there finding no more than 3 or 4 satellites at low levels, even after 20 minutes. By cold start I mean the satellite data wasn't updated in a long time, and therefore the TF is searching on his own for satellites.
When I was connected with Wifi and launched different GPS apps, I was able to get a lock in about a minute or so, which is more normal.
Unless you have the ability to tether to your phone, or or are connected to a wireless router, I think it's absolutely necessary to keep your TF's satellite list up to date manually, or before you leave and know you will be using your TF as GPS device.
I don't think late evening has to do with anything, but the weather can definately interfere (think fog, rain, lot's of clouds).

Currently in the late evening that's what happens with my TF ... I even get a low level around 20 sitting on the sofa 2 meters away from the window.
This afternoon I even had problems in front of the house with a clear sky, where I also had WiFi connection. Yesterday the same experience.
Why is it better in the evening in my case? Strange.
But maybe I have an explanation: On the roof of the house on the opposite side of the street is a large cell phone antenna. Might this cause my problems? Maybe because there's less traffic in the evening?
Problem solved !
I downloaded MapDroid and tested the GPS in the car ... voila ... worked like a charm.
I drove 20km with the TF switched off, stopped, loaded MapDroid, waited until my position appeared on the map, which only took 1-2 minutes and drove back, checking the map at every traffic light.
So it seems, this cell phone antenna on the neighbour house caused my GPS problems at home.
Nice one. I don't think I've actually noticed one of those towers or know what they look like.
ehow.com 's suggestion on how to acquire a GPS signal:
http://www.ehow.com/how_7315691_acquire-gps-signal.html
"2. Get away from anything emitting electronic signals. Radio towers, cell phone towers, and other electronic signals can cause interference with GPS signals, leaving your receiver with little to no reception."

Just google images for "cell phone towers" and you'll find tons of examples. The one on the house is one (!) of this flat long things. The huge masts with lots of antennas you see in most pics are usually not found in residential areas ... at least here in Germany.
well..a trade-off for getting a strong cell phone signal!
GPS Fix worked for me.

Not in my case, but who knows, maybe it helps someday on the road.

I uninstalled GPS Fix, because GPS Status & Toolbox gives me the fastest fix and has more features ... highly recommended

gps not good at all

I hate to start a new thread, but this problem is driving mad. I have spent 2 days researching and I can't seem to find a fix for my problem.
This is it. When I open maps GPS takes about 15 to 20 seconds to fix... Not to big of a deal but what kills me is the GPS will just lose its signal for no reason and then just hang.... Or if I am sitting at a red light the position keeps moving. So one second I am here, and the next second I am there... And it keeps moving about 3 meters.
I find if I reboot then it is good for about 10 to 15 minutes and then it starts all over again.
I am running rooted 4.2 slimbean. 33 radio. But the problem persists no mater which ROM I install. It was also happening on stock before I rooted.
One more thing. I have tried all of the market apps like faster fix and so on. Nothing helps.
Anyone have the same problem or a solution.
I am going to have to sell then phone if I can't get GPS to start working properly.
Thanks to anyone who can help.

Hi,
I'm not sure how you are determining when you have a fix but in any case don't use maps to try and diagnose, use "GPS Status" (https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2) or a similar tool so you can see exactly what is happening.
If you have many tall trees or buildings then any GPS will lose its position and may need to start using network/wifi information.
Hope that helps,
Dennis

Well I consider a GPS fix when the symbol stops flashing and my location is shown on maps. that takes about 10 to15 seconds normally. i am trying to use GPS in the open no tress no buildings, also my previous phone SGS2 never had these issues so I know it is either hardware or software related but as I stated, I have tried different ROMs and different modems including stock before I rooted and I have the exact same issue.
This is unacceptable cause I travel a lot and I need a working GPS. I even use a T-Mobile sim when I travel to the states

I have a Nexus 4 on stock 4.2.2, I normally get a fix within a few seconds when out in the open. I have had no issues with the GPS and in fact its better than any previous Android phone I've had previously (Samsung, HTC, Motorola, I suspect the CPU speed helps here a lot).
I mentioned buildings because traffic lights are generally not in the open country.

Well I drive in city and outside of city. The problem presists either way. I never had these problems with my s2.
If i reboot it could be great for 10 or 15 minutes. Then it starts acting up. I know i have a problem when i see the halo circle around the arrowhead that represents my position. This is indicating that the gps fix is not great and there is uncertinty as to the exact location. Then it starts jumping around.
I installed the gps status app as you suggested and i can see the location jumping around in that app when i am at a stand still. Also it will show that i am travelling 10 km/h as it sees my position is constantly moving even though i not.
Again if i reboot everything will be fine for a while then this all starts to happen. After a bit it will loose my position completly and say searching for gps... Then it will never finf position unless i reboot.
It sounds like a hardware problem with your device.

That is my biggest worry is that it is a hardware problem.
I bought the phone off of kijiji and I don't have original receipt. Don't think I could get warranty claim.
