Rogers Dream GPS Problem - G1 General

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?

Just received my HD and having trouble with GPS. I went straight into Google Maps and selected Use GPS but after about 3-4 minutes it says that no GPS was found. Going into External GPS settings and unticking 'Manage GPS automatically' results in Google Maps saying that no device was found straight away rather than the 3-4 minute wait.
Any ideas?
EDIT: going into Google Maps options > GPS Settings and setting it to Managed by Windows results in me getting a 'Seeking GPS satellites' message but it stays on 0.

ok now just be patient and go to a place where you can see the sky
getting a fix the first time takes some time. you can speed this up using the QuickGPS under programs. This downloads a satellite prediction map so the receiver can find satellites much quicker. Otherwise the receiver has to scan for bypassing satellites, which can take a few minutes to complete.

think I had the same problem as you have right now.
Thanks Gogem. I didn't want to but I gave a hard reset a try then went straight to Google Maps and still no luck. After saying it was looking for satellites for 3-4 minutes it said it couldn't connect to GPS, cancel or retry

as 6Fg8 mentioned you have to see the sky, inhouse or between tight buildings or in a canyon GPS isn't working. and.. this is by design of GPS (!) it can take up to 12 minutes to find the satellites! Technical background: all GPS infos streamed by the satellites have a very low power and data rate. QuickGPS can reduce this time. So be patient. Maybe a 3rd party app like "GPS Gate" (commercial, but 14 day trial available) may help.
Do you have another device to check the GPS receiving from your position, maybe your Blackstone is broken?

ps: http://www.kowoma.de/gps/Signalaufbau.htm (sorry, German language)
Thanks. I just installed Co-Pilot 7 and checked the GPS signal. It must be because I'm inside. I can get 3 satellites on the receiver screen so it obviously is working. I'll just need to take it outside and see how I go then.

in theory you need 3 satellites (of total 31 active today) to get your x-y position on earth and (optional) a 4th satellite to get your altitude. each satellit is running in an orbit of 20,000 km. therefore your max height can be 20,000 km ;-)
in praxis you may see ca 6..8 satellites.

yes in theory, but a lot of people mistake that as a hard requirement->when you pass, you must have a good reception for routing and such.
if you have seen the satellite graph, hte one with two or three con-centric circles, and satellite in or around those circles
you need at least two satellites in the inner most circle (45 degrees) to get a good lock, otherwise you woudl need more satellites to get a good lock.
the circles represent degrees from the verticle point of reference, ie think of you as the axis, and your feet is the origin.
Yeah in theory you need 3 points to triangulate. But I've never had a GPS give me my lat and long from just 3 satellites.
When I first opened my Polaris some time ago, it would not get a gps lock either. I had ordered an external gps antenna, so I hooked it up and got a lock real quick. Since then, I guess the gps chip in the phone knows what the gps signals taste like, so it always gets quick locks and works like a champ. In fact, it worked so well, I never used the external antenna again
LOL must be one of those new fangled learning chips you have there

thats the reason why software like quickgps exists, it lets the gps chip smell where the satellites are. kind of odor transmission tool ...
GPS working fine... just no reception indoors that's all. Disappointing seeing as my girlfriend's new kaiser gets a complete signal in a room with 1 window.

my touch HD gets signals indoors in three different houses. i was sitting quite far from the window, one of the building is my office -> thick concrete walls, etc. i know i should be cheering, but i'm very confuzzled... HOOOW IS IT WORKING with out a clear sight of the satellites?!?!
I was stunned (in a scary sort of way) just how accurate google maps got me based purely on mobile signal (before it tracked any satellites)...
It put the blue dot about 10feet to the left of where I was standing!
i dont know but i think gps is broken - i am loosing signal while driving in highway if i dont have hand up almost near roof - i made today almost 300km with avg speed 140km/h and touch hd gps *realyworking time* like 1/10 of whole trip. I realy think there must be some serios problem, because my co-driver with iphone google maps have totaly no problem

[Q] AT&T Streak GPS problems?

I got my streak 2 days ago and have yet to lock a GPS signal after leaving it outside for 15 minutes and keeping it on all day next to a window. I've tried turning on/off the GPS and rebooting with no success. Any ideas?
Have you tried flashing the ROM?
not that it helps but mine locks almost instantly. This was with 1.6 and 2.1 that i currently have. I use GPS daily and this was the first thing I checked...
Have you tried in an open area away from buildings?
You may be near a window but say the satellites its trying to lock on to are come from the other side of the building/house?
For example I used to have an apartment on the 3rd floor facing north and it would take forever to get a lock near a window or even out on my balcony. The second i left my apartment and went down the hallway to the window on the other side of the building (south side) i'd get a lock instantly.
Not saying south is the way the device should be pointing, but your location does help you get speedy locks.
I haven't got my streak yet but i'm pretty familiar with reg-editing windows mobile devices to get a lock instantly (cab in my sig for example).
Make sure you have the correct aGPS server and aGPS is enabled (i don't know how to do that on android yet but look through menus and see if you can find that).

I had a similar issue, I did a factory reset and everything works great now!!! Maybe that will help....
Still no luck...
I tried a factory reset over the weekend and still had no success. My old HTC Fuze works fine in all the same places, so it is definitely an issue with the Streak and/or the build AT&T put on it.
I called Dell about this too - they suggested the device was working fine since it picks up a location when you choose the "Use wireless networks" in Locations. I tried to explain that this data come from Google's database of cell towers and WiFi hotspots, not the GPS signal, but I don't think they understood. I tried several other GPS diagnostic apps and none of them pick up any GPS signal or otherwise work at all, so I know there is something wrong.
I asked to escalate the issue and to get a replacement unit, so hopefully that does the trick.
Have you modified APN? (Remember to enable "supl")
Did you turn on the data connection?
New unit works
The new unit worked right away. I picked up 8 satellites sitting on my couch within 30 seconds - no where near line-of-sight with the sky and where none of my other gps-enabled devices work.

[Q] Its official my new vibrant no gps issue and signal is better.

I've tried every fix, every change and every hand position and the gps was still unacceptably slow and useless. After several phone calls to TMO I finally convinced them to send me a new phone.
I unpacked the new phone put my battery and sim card in booted it up clicked on google maps the gps flicked on and off about twice and then locked gps within 35 meters. Then I double checked the settings and use wireless carriers was unchecked.
Also my signal shows more bars. It still goes from 2 bars to 4 bars if i hold it by the top upside down but it was showing none (still worked) then 4?
This begs the question to me, is this a hardware issue? software? if it is soft why if they can fix on the later batches cant they fix for everyone?
New phone about:
model sgh-t959
firmware 2.1-update1
baseband T959UVJFD
kernel 2.6.29
the tech also told me to periodically do *#*#checkin#*#* on the dialer to be in the first people to get OTA updates when available. Anyone ever heard of this?
Thanks, i've been on this forum since my TMO pocket pc phone but this is my first post.
sax911
*#*#checkin#*#* or *#*#2432546#*#* is technically pinging google, sending your phones info... in the event you are on an outdated OS version you will be upgraded soon. It's not a waiting list, no one but Cyanogen goes first. then he gives google the go ahead to ship it out
For what it's worth, my phone was packaged on 8/19/10, and takes a long time to find GPS signal. I did both fixes, but ended up reverting back to Standalone mode to get semi-consistent results. Once it's locked in, it's very accurate.

does anyone have anything different from this? i picked up my vibrant a couple days ago, and my info is the same as this.
my gps works fine outdoors, sometimes has trouble determining location indoors. signal indoors usually shows 0-2 bars of 3g with consistent speeds, with full bars outside.
i can't complain
^^ The one I ordered from Amazon on 8/31 and got delivered yesterday has the same firmware, version etc. Today morning tested GPS on way to office and no problems. Locked satellite in 2 secs and did good job re-routing couple times when I ignored the GPS lady. I dont know if the problem starts when you use GPS more frequently. Hope not!
mind checking the GPS settings and telling us what they are? maybe some screenshots with drocap?
That's great for you but a single anecdotal data point is not an official fix validation.
I just tried *#*#2432546#*#* on my vibrant and got no results whatsoever. I have rooted with the one click root but have not installed any roms. I did do a backup rom with Rom manager and I believe it ended up with clockworkrecovery mode. I have done nothing else. Has something occured that will make it impossible for me to get the OTA? I have gotten checkin successful in the past but now nothing. Any help is greatly appreciated.
OP, this is by no means a flame but locking on with 35 meters accuracy is EXACTLY the issue with the GPS. That's 100 feet, man. Not accurate in my book. With aGPS turned off, my mt3g gets within 2-5 meters in about 20 seconds. Do a GPS stats test and see how many sats you lock on. I'll bet 1 to 3 at best. If more, post pics.
Mine works after using that fix that's been going around. Only thing is that out takes a while for the gps to lock but otherwise its fine. I think lol.
Sent from my SGH-T959 using XDA App
I got a new one, my GPS locked in 10 seconds up to five meters

(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 .
jje
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..

I think i'll keep trying until i get a first lock before i send it back to warranty..
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

Will do.
I'll report back as soon as i test it
Thanks
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!

[Q] GPS Problems

Edit: I actually just though of something, I updated to NF1 about 2 or 3 weeks ago and the problem started happening within the past few weeks. Does the baseband control the GPS radio also?
I know this is a problem with the Note 3 across all carriers, but it also seems to be a stock software issue. I'm on an AOSP ROM so none of that really helps me. GPS will lock on to my current location, but it won't "follow" me and it loses it's connection after about a minute and then it will sporadically update my location. I noticed this for the first time last week (I've had the phone since April/May and it has worked fine up until now) when I was trying to use Maps to get to a town a half hour away. I would open Maps and it would find my exact location and give me point to point directions but before I even moved it would say "GPS Signal Lost" and wouldn't reconnect. After about 3 or 4 reboots I finally got it to lock on and follow me. One the way back I could get it to follow me at all.
I recently started playing Ingress since I work in NYC and live right outside of it so there are a ton of players, the problem is that the stupid map won't update my location so the marker usually just stays in the same location, but will spin around depending on which way I turn. It will also occasionally update my location, for example, on Sunday I was able to play for 2.5 hours because it would actually follow me for a good amount of the time, at about the 2.5 hour mark it pretty much stopped updating. I had walked 3 blocks from where it shows me at that point I got frustrated and went home. During my time where it actually "worked" it wouldn't be that accurate, I know GPS isn't accurate down to the exact foot/inch but this would be pretty far off. I'd be standing next to portal (shown by the picture) and it would say that it was 50 or 100 meters away!
I tried to play yesterday in NYC and it wouldn't even follow me at all over the course of about 5 blocks! I got frustrated and stopped playing the game. During this time I had flashed two different AOSP ROMs and neither have fixed the issue.
GPS Status shows all the correct info, except for "waiting for GPS location....". I saw that someone mentioned checking/bending the GPS contacts but I'm not sure which ones they are and don't want to screw anything up.
Does anyone else have these issues on AOSP ROMs and if so, did you manage to fix them?
I'm currently running:
C-ROM Kang v1.6 20140816
Kernel Version: 3.4.0-gd84d543
Baseband: N900TUVUDNF1
