Rogers Dream GPS Problem

So I've had my dream since launch day in Canada, and the gps has been working fine until about a week ago. Recently my gps mostly refuses to lock, and when it dose, google maps shows me as being roughly 600km away from where I am.
I just went out for a walk to an area with no buildings or trees to block the sky, (I have had success locking from within my apartment building before, but just to make sure...), and it took about 30 min to establish a 'lock' on my position (600km away 5 km below sea level and moving at around 150 km/h).
GPS status showed between 5 and 6 satellites that it could see the entire walk. I then installed gps test and got roughly the same. I've tried rebooting several times, as well as leaving the phone off for about an hour.
Nothing seems to clear this issue up.
I was wondering if anyone else has had this problem, and if they got it fixed?
I'm currently running a rooted phone, did that several weeks (and a few reboots) before the gps issue cropped up.

Take it far away from tall buildings. Signals can reflect off of buildings and give you incorrect readings.

I used to be able to lock under a minute, now I can't lock at all. Same here.

hmmmm, I just opened up GPS Status 2 app and I'm not getting a lock either.
I'm guessing google maps is just using phone towers to approximate where I am.

I hope Endeavour didn't crash some sattelites on it's way to the space station lol

turns out my GPS is fine. I thought it worked inside my work place but it does not. It had no issues connecting while Iw as outside.

so I got in touch with rogers technical support, they put me in touch with HTC technical support. they said that it's most likely a hardware issue, and told me to get back to rogers. rogers is now saying it's an application issue, and are directing me to talk to google.
yey rogers....
sigh...
..EDIT..
and three factory resets later I have gps again...

GPS not working

Hi...
Up until Sunday, my Sat Nav on either Co Pilot or Google Navigation was perfect - it knew exactly where I was and was incredibly accurate (and I use it a lot!!).
On Sunday, for some reason, both sat nav apps can't seem to pin point my location and think I'm up to 30 metres away from where I actually am.. which then has a problem with navigation as it thinks I'm on another street (or if I'm on the motorway then it thinks I'm in a field!!!)
I tried re-installing the phone software (using PC Companion, so it was completely a clean install) and this still hasn't helped and it has happened for the last couple of days.
Can anyone help me?

Do you have AGPS active?
It might help.

Hi TuxStyle,
I've got all the options active..
It has been working without problems since I got the phone, I travel A LOT, sometimes I think too much, but it's never done this..
Since Sunday it's just become very inaccurate and annoying as it thinks I'm on a different road.
None of the settings have changed and I've re-flashed the phone using SEUS and re-installed the apps to make sure it wasn't a setting.
Still having problems...

This exact same thing happened to me on Friday.
After many months of my GPS working impressively flawlessly,
suddenly it is totally useless...
Loses signal a lot, cannot accurately locate me, etc.
No change in settings, no new apps installed, nothing...

HOW STRANGE!!!!
Sorry to hear that My_immortal, though I'm glad someone is experiencing this as well.
Don't flash your phone again, it doesn't help!!!
It might have happened earlier for me, though I hadn't used my phone for sat nav since Thursday (when it was working fine)...
Do you think there is something with the satellites? (Highly unlikely since there's just 2 of us experiencing...) or something to do with hardware?
Mine is R2BA026 as well, UK, Unlocked

hmm.. i suppose a lot of factors affect how accurate gps is... like.. how many satellites the phone is using for triangulation.. any buildings/obstacles whatever nearby that can cause interference(?)
mine works great though, 10m accuracy. without gps, and just 3g alone, it's a crappy 500m.
you can download an app called GPS status from the market (free), shows you how many satellites your phone is locked on (mine usually fluctuates around 10~11) BUT i'm not sure if it's a fluke or real, but i think it is real, because it showed me 10m accuracy, when i checked on google maps, it mentioned 10m too.

Hi Tookieboy,
Yeh on G Maps, I get accuracy of 10m, but when using Google Navigation or Co Pilot for actual sat navigation, it thinks I'm on another road (or in a field next to the road I'm actually on), so before it was pristine and knew exactly where i was, but now it doesn't..
no settings have been changed so it seems strange..
Co Pilot shows good signal from 11 satellites so again... confused :s

clearing the cache help? maybe a bad byte somewhere? i dunno..

Seems to be fine here in Canada thus far. Used it today and it was spot on. I do not use the AGPS just gps and so far so good.

Hi Rockjock, thanks for your input, but I'm still having problems.
I have 11 satellites showing, so technically it should be positioning me on the correct road.
I have tried all variations of the location settings.
I had a look at the cache and it appears empty :s
Any other ideas? It's just strange that it started randomly on Sunday..
My_Immortal, have you had any luck?

AGPS helps to get the lock faster.
I didn't try driving navigation. Only walking and from what i see, i'm about 10m away.
Maybe if two roads are close i would have the same problem.
I'll do a test in weekend.

I tried it yesterday, still unusable.
Oddly, it could locate me accurately when still,
but when my car was moving it lost signal often
and the accuracy grew smaller and larger,
so no use in navigation...

tried it out last nite and again it was spot on. Speed was almost perfect and it did find me n the right roads and was dead on. If it just happened all of a sudden it could be a satellite issue. But you need only 3 for a positive lock. BTW I using co-pilot live 8 ... have you another handset to try out?

i'm havin same issue today with google navagation but everything is workin alright with co-pilot.. since google nav is beta version here in canada, that could be the issue for me...

Did you try the GPS test from the Phone's service menu?

just in case you don't know, the combination to access the service menu is..
m b b m b m m b
m: menu (left most button)
b: back (right most button)

searching for GPS

had the phone a couple of weeks and never tried the GPS on it ,so this morning decided to give it ago
in premuim navigation or google navigation it just says searching for GPS all the time with m3g on or off, out side with 3g on i get a spot on fix in no via that in no time but if i try to get the gps to get a fix it just keeps saying searching for GPS
i know it normally takes longer for its first ix and then should be ok but i cant get a gps fixe and yes GPS is enabled
any help would be great thanks
Just a update with 3 g on good navigation provides a fix and directions but with 3g off Google says mobile data lost,on premuim navigation it just searches for god and can not provide directions even with 3 g on
Sent from my Desire HD using XDA App
just a update after a bit of trying things out today
got GPS in car panel after a while and now it gets a fix very quick
premium navigation works well on 30 day trial and is very acurate for proximity to junctions etc,this does work with 3G turned off no problem (although 3 g does need to be on to activate the trial)tried it tonight in awful weather and never once lost the GPS during the journey
google navigation again gets a very quick fix but will not work unless 3G is on other wise you get the voice saying loss data connection when trying to plan the route
google maps very quick fix and only needed GPS on
locations, not sure how this is working but im sure even with just GPS on i was getting acurate info or maybe it was pre-cached info not sure

Thanks, this helpful.
So after you got your initial fix, the next time you start navigation, the fix was quick?
Did you also test that without using 3g, so creating a fix without 3g, and if so, was that quick as well?

mine just will not fix the GPS....it finds 8 satellites in couple of seconds, but then just keeps "determining position"
without a determined position, my nav app can't do anything (copilot btw)...
Anyone any suggestions?

Locations sadly does not work without data connection, even with gps turned on.
So whats the use of preloading the maps?

Exactly! I pre-loaded with maps of Europe so as not to incur data charges - but Locations is useless without a data connection. How do you use the maps with GPS only? Does anyone know??

You guys are doing something wrong. I'm in Australia and Locations works fine without data connection after having downloaded the maps. It just takes some time to get fix (some 2 minutes) if it was a long time since I last got one. I can get directions fine without any data connection as well.

I'm also having problems with gps, worked fine when.I got the phone but now after I think the third ota update it just keeps searching if I only have gps switched on and not wireless networks. With wireless networks one (with or without gps, dosnt make any difference) I'm consistentlyplaced 2km away and it dosnt.improve the accuracy with time.
So I'm thinking that the updates have messed it up? Did email HTC support but nothing yet from that.

I'm always unable to get GPS fix, even if I'm in an open space. I used an app called "GPS Status", I was connected to 7/8 GPS satellite, but I wasn't able to get my position (in Maps, Locations, Latitude and Nav). How is that possible?

So you're not able to use navigation stuff? I'm still waiting to get mine, no availability here in Milan, but for me GPS is a critical feature, so if not works properly it will be a big deal!!! Let me know on that!!!

I've noticed that I am unable to get any GPS fix indoors, even when I am sitting close to a window. I presumed it was because I wasn't outside but this thread is worrying. I'll try to get a fix outside and report back. One thing's for sure - the GPS on the HD doesn't seem as good as the one on my Desire, which found GPS indoors.

I can't get the fix even if I'm outside. I was in Rome in the past 3 days, and I never got the fix! The iPhone 4 worked fine...

UPDATE: I got a fix, pretty quickly, outside (in a city) but it is still unable to get one indoors - including on buses and trains. My Desire managed this.
Does the HD's sat nav work in a car? Are people using it for in-car navigation?

I had problems getting my GPS to get a fix, so I downloaded GPS test from market and noticed I actually had 11 satellites that i was connected to. When GPS test showed how accurate the tracking was I exited out of GPS test, and to my surprise I got a fix almost instantly in Google Maps/My Tracks and even Locations.
I then took a drive, first with my DHD laying in the passenger seat on the first trip, and then with the DHD in my inner pocket of my jacket. Using my tracks I recorded the route and it had tracked me perfectly on both trips. Only time it stopped tracking was when I went in to a mall, but it picked up again when I left.
I live in sweden and the car is not a convertible, and 3G was off.
If the gps test thing actually helped I do not know, so feel free to test and report.
edit: I tried it again and the only thing about gps test "helping" is to see when the DHDs gps actually get a fix. It seems to be slow as crap on fixating but once you get the fix it tracks you very good. Right now I'm indoors(wooden house out in the countryside) and I had to wait about 2-3 minutes with 8-12 satellites in use and standing near a window before it got my position. After that I went back to where I tried before and it is still tracking me with 15-30meters accuracy and currently 7-8 satellites in use.

Those with GPS issues can try this, remove the battery for 10-15 mins then try GPS app again, ports can get messed up if we try out multiple GPS apps, removing the battery for a length of time should clear cache and or memory. Just try it and report back.

I tried alreay couple times, no luck, only fix is reset phone, but not happy, working fine couple days, and issue again, reset again, really not happy, this only one thing i am not happy on my dhd. ANY ADVICE or HELP ?? thanks..

Hello,
I have some problems too with my GPS. Some times the fix can be very quick but it’s not systematic.
What I noticed:
- When I activate the GPS option all the time, the fix is almost always fast. Sometimes it’s still very long: so in GPS status I reset the cache and the fix is after very quick.
- When I activate the GPS only when I need (turn on and turn off before and after using Navigation), I never get a fix. Resetting the cache in GPS Status or restarting Android does not solve the problem. So I launch several times GPS Status to reset cache and several times Navigation and after a while I can get a fix…. I think there is a real problem with the management of the GPS, because in GPS status I can see 11 satellites and Android is still searching!!!
Is there anyone who noticed that turning on and off GPS can seriously degrade the performances to get a fix?

I done few very similar things, clear cache, reset phone, but still I had feeling something was wrong, then I find I had faulty gps receiver, hardware issue, replaced for new one, thanks to very good store manager, and now I have black DHD, before was brown, and already new one is have all latest update installed, GPS lock in couple seconds anytime on open air, inside house It will lock in around 1 - 2 minutes longest, no more resets, no more clearing cache, working on 100 %..., this is just what I find myself, and I glad I had replaced mine old for brand new - and not just repaired..

Damned, I hope this is not an hardware issue ! Maybe you have some updates installed on your new phone which solve the problem ?
Is there anyone who noticed the same issues or I am the only one ?

(SOLVED) GPS signal lock issues

Since my phone arrived that i can't get a GPS signal lock.
GPS Status can indeed see the sattelites but phone can't lock a signal...
After a lot of cache and factory wipes still no luck.
Anyone else having this problem?
How fast can you get a GPS signal lock?
I would like to see some other opinions before i send it back to warranty because it might be something fixable..
P.S: I've searched all around the forum and the web and i couldn't find a solution for this.

Cold boot lock 180 - 250 seconds .

I had similar strange issues the first 2 days.
Then when I finally had a lock, I started using gps more and it works fine now.
It's almost like the gps module had to be warmed up
I read somewhere someone had a similar issue in the beginning and then it worked fine.
I'm also keeping an eye on my gps functionality..

Just flashed back to KE2 to see if it's really not fw related.
I'll post the results after some tests

Do you guys have location service turned on? Not the one based on wifi but cell service?

try the following and tell us if it helped:
1) turn off the wifi- and cell based gps support (this doesn't help you much and sends your pos data to big G)
2) download "GPS Status & Toolbox" app from the market
3) download the actual satellite vectors with this tool (this you will have to do regularly, around once a week)
4) go out, start your nav app, do NOT move (easier for the GPS to get a fix)
5) come back in and tell us if that helped.
Cheers

Also make sure you have 3G data (not wifi) turned on.
I noticed that when 3G data is not on lock takes ages.

Everything works fine now.. I didn't know that was necessary to have 3G enabled.. At least the first lock.. After that, with 3G ON i was able to get locks within <15 seconds. Also, after this, with 3G OFF, and after rebooting phone, i got a lock within <15 seconds..
I guess my GPS is not broken after all
Thanks everyone who helped

I don't have 3G and neither do I enable any network. Here is a screenshot i took todays while sitting at a caffee. Maybe the fix takes a minute or two, but then it's very stable, does not loose the connection easy.

ive always locked in about 10 secs from day one every firmware ive tried, always held a solid lock too,best gps ive used yet phone or otherwise.

I'm now having fast locks too without 3G.. Even inside my house, on a 4 floors building (i'm on first) with all windows closed, i'm getting locks within 30 seconds.. Not bad. With 3G ON, it gets a lock within 20 seconds max.
Haven't tried outside yet though.. Will do tomorrow with 3G ON & OFF so i can compare both.

it may have been the timing but i couldn't get a lock as soon as i got out of the subway station on saturday within 20~30 sec ish. So i closed google maps and enabled location service and bam 5sec and lock
I tried it with wifi earlier this evening and it jumped around a bit (never had this issue before)

Haven't tried google maps outside yet, but inside i can say it takes forever to get a lock.. even with 3G ON. However, when it does get a lock, accuracy is really bad (>60m).
On GPS status, GPS accuracy is also kinda bad.. I can't get down of 20 m of error (20 m min.. usually it's around 40/60). However, lock times are faster than on goole maps.
Is there a way of improving accuracy?

Being inside and trying to get a better accuracy is not really possible. With 3G on the GPS will use Cell tower triangulation to get A-GPS which is not very accurate indoor.
Use GPS outdoors!

GPS- success with phone orientation...

I know this sounds crazy.. and until I tried it over and over.. I did not believe it either..
I did the hardware fix , where you bend up the gps antenna a bit, so it touches the cover when closed. but I litteraly had almost no change in signal.. like I could not even get the GPS restore to work..
I was pi$$Ed..
so I took another look at the phone / antenna etc.. got be thinking about signal and its orientation.. the GPS ant. is on the back of the phone, where it gets covered by your hand faces the ground or whatever is under it.. so I turned it- landscape..screen facing me.. clock wise... so the e from tmobile is top side..
guess what.. it works
I am locking on to 9-12 sats..every time..
let me know what you find happens..

How fast are the locks. Te issue is not how many sats since it only needs a few to get an accurate signal. The problem is that the phone takes 1900% longer than any other phone I've ever used to lock, which makes the GPS functionality virtually useless for geotagging pictures and posts to Facebook, twitter, google+ as well as checking into places.
Until it gets a decent lock the bubble around your location is miles in diameter.
Phone literally take upwards of 10 minutes to get a lock at times.

a little exaggerated perhaps? my phone is the original batch and i've never had it take ten minutes for a lock. i mean i'm in Manhattan so the wifi assist probably helps it alot in terms of lock. the gps on the vibrant was never good enough for navigation but good enough for everything else imo.

I don't know about you but all my gps successes didn't last. first time i did all my gps fixes, it worked great. as time went on, went back to sh|t.

10 minutes it about right for me at the moment... ill try the orientation thing lol

Yea one of the members here found this out a lonnnng time ago ever since then I always face my phone with the back facing the sky to get that first lock. Most of the times it works

Agreed, same experience I've been having. There are some good days and there some days that it's flat out stubborn like a bull. It won't even lock even on a clear night sky.
