[Q] GPS sometimes can't locate despite having fix on 8 satellites

My almost brand new Desire HD just can't locate me sometimes, despite having fix on 8-10 satellites.
I use GSP Status, A-GPS is on.
One day it locate me in a few seconds, and on the other day it takes 10 minutes, sometimes even more.
Just before I wrote this post, I've reset my A-GPS data, downloaded new and went out to try it. I was walking for 5 minutes and I've got fix on satellites, with good signal strength. So I've switched of the phone,reset A-GPS, download again and still can't get location.
My brother with his HD2 has no problem getting location.
Do you think that I should contact HTC???
thanks

its normal...it all depends how fast the sat..communicates with dhd... i too have same issue...but it is place specific issue not dhd... enjoy man

My one tends to behave like that too. There are many environmental factors that affect the signal of the satellites seen. Also I find that if one app gets a GPS fix, switching to other apps seems not to pickup the coordinates from previous fix.

Mine is faulty too...!
Yes I say faulty, becource my sonyericsson x10 ALWAYS get a lock on the location within 10 sec...
Even when I compare them side by side, the x10 works MUTCH better...
By a 10:1 factor or so...
And it is also mutch more accurate when it is locked on to the gps...
Also about 10:1...
Htc make fine phones, not so mutch gps...
I had a thread about this, here a few days back...

A longshot, but would plugging in headphones help increase GPS signal? I always wondered whether they could make such a mechanism for even boosting the 2G/3G/Wifi signal. Given they've already exploited this for FM antenna...

My gps locks in 3secs in my back garden with only 5 satellites turn satellite layer on and it shows location it back garden not the nearest road SO IT'S NOT FAULTY IT'S NOT THE HARDWARE. It's the silly gps apps you using you don't need them just turn on gps open Google maps that's it the only gps app I use is gps toolbox for calibration that's it as for comparing to the x10 haha a great phone NOT
From England with leedroid dhd techo!

Just reboot your phone, make sure your in the car or clear view of the sky and try again.

Probably wont work as the antenna for GPS, WiFi and Bluetooth is under the battery cover.

Are you shure that the gps antenna is there ?
I have tried to remove the two covers on the phone and didn't see any difference in the gps signal...
But I have been thinking about why there is terminals on both covers...
- any one know for shure ?

Well, I'm not too sure where the GPS receiver is located, but I'm definitely sure that the GSM antenna is under the SIM cover and the WiFi/BT antenna is below the battery cover.

The GPS antenna is in the plastic cover surrounding the flash LEDs.

I've tried to get a lock on DHD and HD2 phone by phone and HD2 got lock in a few seconds and my DHD just couldn't. So it's not place issue.

How is the GPS on this beast?

Can you lucky bastards with one of these in hand post some GPS test screen shots please? And overall GPS performance ....I'm an owner of a vibrant and need a working navigation phone ...also does vzw let u use Google maps or is there some fee for using GPS?

Navigation is great. It takes about 30-45 seconds initially to figure out its compass direction and then it's perfect from there.

Apple hand picked their hardware for a reason. Android devices have to follow in line with "But are there drivers for Android yet? If so, we'll just go with this GPS module."
Plus, ICS should be a lot quicker polling for GPS anyways. It's probably mostly OS related.

Went out to my backyard to attempt my first GPS lock on the phone. Took about 5 sec for a full lock with multiple sat. (Not complaining, since my g2x would take like 40 sec.)

Check out: http://forum.xda-developers.com/showthread.php?t=1360278

It has a barometer, which helps with super-fast GPS lock. Even indoors (google indoor maps for malls, etc, is useful finally).

Just installed GPS Status, instantly locked and went from about 15m to 10m in a second.
It's overcast/rain and that's from my screened in porch. It got 9/9 sats right away.
The best from the same location/clear day with a charge or bionic is 5m.... but that's waiting for a while and holding it still.

i´m impressed
get my phone last week and atm sit down in my rom, playing with google maps and after 5 or 6 seconds wtf o0 ?!?! what is going on?!?! i got a gps signal in my rom?!?!?!
it´s my 5th android phone and bevor that i got 3 nokia phones with gps and non of this was able to get a signal in my room.
it´s funtastic

Coming from a moto phone that takes 2 minutes on a good day, it's solid.
Have only driven maybe 100 miles with navigation, but it's been stable so far regardless of where it is in the car.

2 minutes? be glad
my last phone was the optimus 2x and i´m glad to be rid this piece of ****.no more words for lg software developing.nice hardware but fail software.
2 weeks ago i was in spain (Teneriffa) for one week and it needs between 5 and 10 minutes to get a signal and lost it every 10 or 15 minutes...
In germany the same.itßs nice to have a phone with gps and you can not use it
i´m glad that i can drive now with my gn and my holidays are safe

Excellent GPS specially when coming from Captivate with a busted chip.
sitting here in my room ... I got 9/9 in around 10 - 15 seconds.

No faults whatsoever!!!

Hello everyone I havent posted for quite a while.
I recently bought a HTC ONE X white serial number HT23SW.
simfree. network O2
When I first turned it on it immediately powered down since there was only 3 % battery charge. I plugged it into a power source then powered it back on.
Connected it to my wifi n router 5 GHz (I've renamed both my 802.11n SSID channels with the suffix 2.4 and 5.0 GHz respectively)
It then prompted me again that a 33MB software update was available.software 1.28.161.9
I charged from 3 percent to 60 percent then applied update.
Inital impressions ..... I had my phone plugged in for the majority of the day even though it had 85 percent charge I do beleive there is an eeprom which contains battery calibration data. Now my battery life is stellar.
No problems whatsoever after the 8th day. This phone is a beauty! ( I hope I am not speaking to soon)

If you have the time please post some screenshots of especially screentime. But also the total hours and other details would be cool. I would love to see a 4 to 5 hours screentime.
Cheers

Have you tested the GPS's ability to make an accurate track with an app like RunKeeper or My Tracks?

I also have a flawless grey HT23SW HTC One X

I thought mine is flawless as well until I saw how ridiculous GPS behavior is. On Google maps my position is just floating all over the screen...

Had no problems with mine everything working great battery life took a while to pick up but seems to be going quite well at the moment very happy with my device

I hAve a white one which so far has no issues.great gps,screen, sound and Bluetooth.battery life seems on the up as well.
Sent from my HTC One X using Tapatalk 2

Yes I will post the battery statistics. If I remember correctly I had over 5 hour screen time and 33 percent battery left.
What was quite strange is that I left my phone at 89 perecent a couple of nights ago and woke up the next morning and stranglely It was still at 89 percent. This must be where the companian core comes into play with negligible quietscent current drain.
I have used the stock maps programs to check the gps hardware and it locked onto the satellites in under 20 seconds maybe earlier, The program mentioned that the accuracy is within 20 meters but what I could tell it was accurate within a meter (I checked the accuracy at each junction/intersection I came to)
so yes it working flawlessly. I played teeter (level 21) and checked the gyro no problem there. I am really impressed with the wifi n 5GHz browsing speed (unsure whether it is dual band) but it like its on steroid faster than my i7!! laptop in some instances. no over heating when playing soul craft THD.

I'm not sure your testing method is sufficient to declare the GPS as flawless. You just sort of spot checked.
Would you mind downloading the free app called Run Keeper and using it to record yourself walking around the block or something similar?
Check out the consistent results I get doing that. For any kind of tracking app, the GPS in my HOX is just about useless. A half mile walk records as three miles with a walking speed of 2 minutes per mile. Not even olympic athletes can walk that fast! LOL
For perspective, I walked a straight line down the sidewalk from where the pin to where the 2 mile flag is. Everything else is just BAD data.

in relationship to the testing of the gps I didn't do a spot check. I did a dynamic test at full zoom and the result that the arrow was moving smoothly at the correct speed. . I will down load this program today and post a screen shot

I use Endomondo to track my runs and it is prettty much perfect. Have also used the sat nav for around an hour and found it to be spot on.

Had no problems after 1 week but then started noticing a screen flex and back light bleeding. Gl for now guys

No screen flex.light leakage or flickering, Bluetooth A2DP works fine with my SONY DR-BT216.
tested the Near field communication and that works. oh I forgot the compass works perfectly it didnt on my htc desire.
Btw my phone is unrooted. My friend at work also has the same model with same serial prefix. he had it 6 weeks. and he also has no problems also. I just cant understand why people have so many problems.

I haven't found the plethora of "GPS Sucks" threads that we used to see on early Samsung phones like the SGS and Fascinate, but there are enough random comments in the forms about GPS flakiness to show it's not just me. Someone else mentioned issues in this very thread. Perhaps we're just a few unlucky folks with bad hardware.

Sorry, I misunderstood how you tested. Read it as you just checked your location when you reached intersections.

I also tested with Endomondo Pro. Actually, it was Endomondo that made me first notice the error; Runkeeper was the "second opinion."
Here's a track made with the HOX of the same walk going the other way.

How would you rate the GPS performance of your nexus (poll)

Please vote (1-unusable, 2 barely usuable, 3 adequate but not great, 4 good, 5 awesome)
Ive had this phone for about a month now, and i love it, but the GPS for me has been awful.
When i first got the phone, it would work - but not great, sometimes not locking, losing signal while driving frequently, etc. Then i went on a period where it didnt work AT ALL. Randomly that started to work again - but only as good as it was before.
Currently:
Takes forever to get even a mediocre lock
VERY inaccurate - usually around ~30m at best
Loses lock
I thought maybe it was just my device, but i met a couple the other day who both own the Verizon version, and they were running ICS, so i ask them if i could run a few tests, and to my surprise, both of their phones were just as bad as mine. Ive heard a crappy GPS might be a JB bug, and will be fixed with the next update - but they were both using 4.04 - so no jellybean bug there.
Basically - for me the GPS is unusable, because if you cant count on it, whats the point. I had a doctors appointment the other day, and luckily i knew the general direction - because by the time the GPS kicked in, i was getting off the highway. I was about to just type in directions manually, and then just find the place like that. Maybe samsung just sucks at making GPS's (i used to own a captivate )
I also have started using endomondo to track my runs, and even that sucks. I started and stopped at the same point on my street, but according to the app, i stopped running about 30m short of where i actually did. (GPS gave out, or just never realized that it moved.)
How is the GPS for you??

Voted 4. I geocache, so I need a decent GPS receiver. Since the "Great Nexus GPS Outage" a week or two ago, the GPS has been adequate. It locks within about 15 seconds, and the lock has good accuracy. Lately I have noticed that even a "warm" lock takes 10-15 seconds. Warm locks should be basically instant.
I'm in the habit of launching GPS Status and allowing it to download the assistance data and get a lock before using other GPS apps. Not sure how much it helps.
Yesterday my data connection was unbelievably slow and GPS accuracy was awful. I had nearly full bars of HSPA reception, and 9 good satellites, so it didn't make any sense. Rebooting fixed that, thankfully, but it was odd that both features degraded at the same time.
I do wonder if the GPS subsystem relies on communication with some site on the 'net. Maybe that would explain why the "Great Outage" affected only Galaxy Nexus devices and not others. During that outage all of my Garmin handhelds and several other Android devices got decent locks in good time, while the GNex took ten minutes to get a poor lock.
Edit: why the heck do I have to wait 2 minutes to submit changes to a post?!

This whole situation reminds me a lot of the galaxy s1 bs that i went through. The gps clearly sucked but some defended it. People came up with a bunch of hacks that did basically nothing, and the problem was never fixed.
How is it possible that the flagship android phone has terrible gps ? How are developers supposed to design apps on it that use gps? I think the nexus s was the same way. Wtf Google. I might be returning this if it's not fixed completely with the next official update. According to whoever i talked to in customer service, should be within a few weeks.

I voted a 4.
I usually get a GPS lock in under 10 seconds if outdoors and under 30-ish seconds indoors.
Outdoors, I typically get an accuracy within 10 feet. Indoors, it can get a bit worse, but is still usually within 30 feet.
I've never had the GPS lose lock.

Voted 4. GPS locks come pretty fast for me. Accuracy is also OK, but it does lose its lock once in a while during a bicycle trip. I do have the phone in my pocket, to be fair I should test it when it has a clear view to the sky (mount it on my steer or something).

4-5 for me. It works pretty good for me and acuuracy is there.

5. Went on a thousand mile road trip and never lost a lock for even a second. Navigation worked flawlessly.

I can't use navigation it says Google Navigation can not be used in this location (Turkey)
I can just take rooting.

Used yo be really good but since the outage its been crap. It'll get a lock and give me directions but then randomly it thinks I'm two blocks away and start rerouting. This happens a lot.
Sent from my Galaxy Nexus using xda app-developers app

I travel a lot with the Nexus GPS. It serve me well all the time. Takes about 10 seconds to locate and never loose signal. I give it a 5.

I have no need for the GPS and such but I decided to open the navigation app and boot the gps, i waited for 3 minutes with the screen saying waiting for location till i just gave up and shut the gps back down

Voted 4/5. Out of the box, it took forever to lock and even then was only hitting on 4-6 satellites. My previous phone (Epic 4G) was notorious for this as well. Used GPS Status and all is well again (lock usually within 5 seconds).

I am a car parts driver and i constantly need the use of my GPS one thing i noticed about the Gnex is that, the GPS VARIES ON the phone provider and plan you have the faster and beter your mobile network the better your GPS WILL work for you! NOW the reason i gave the Gnex a 4 star is because even with 2G edge networks the gps will work while driving within a minute but the process will lag a bit longer not due to finding the direction either but due to locating the gps signal..

GPS sensibility ??? His there a problem ???

Hi
I'm using my GN for the first time in holydays with GPS fonctionnality...
GPS statuts, icoyote and sygic...
There is no real problem with GPS fix but the gps signal is worth ... precision is 15 or 25 meters. My wife with her Motorola atrix dont have GPS problem !!!
The navigation is lost to many time

It's hardware problem, i also tried all latest roms and kernels and the result is the same. My problem is very difficult loc with the sats. i can see different number between 8-11 sat but loc is forever and accuracy is 5 meters. for example my old nexus one loc for 3-15 sec outdoor @ 2 meters. and indoor 5-30 sec. @ 10-15 meters. The GPS of Gnex is shame. I'm very disappointed from Samsung.

Just tested mine and got it accurate to within 5 meters, took less than 10 seconds. But I've had GPS problems before... sometimes it takes waaay too long to find a lock, sometimes it can't find it at all within the first day of flashing a rom. I would recommend trying a different rom. The GPS worked for me decently well with Vicious AOSP and is working flawlessly now on CM. As I said before, I used to have issues with it right after flashing a new rom and would have to leave the GPS on for a while before it eventually found it (sometimes like 30 minutes) but after that it would always get a lock relatively quick. I haven't flashed any GPS fix or anything like that. Hope that helped.

As i saw better than 5 meters outdoor nobody can do. Indoor what is the situation?
