I have had the same problem as most people with the 10 + minute lock time on gps for google maps. I have tried the gpstest trick and it helped. Today as usual I was reading and rereading posts here and tried out the secret codes. I used the gps code and changed the gps boot from hot to cold and now after several tries about 10 minutes apart and 1 with gps off for over an hour and turning phone off and on a couple times. I am getting a lock in less than 30 seconds every time.
Sometimes initial lock is off by 100-150 yards but within a few seconds it drifts to proper location and locks.
I know that this takes a lot more testing and I may not have actually fixed anything but wanted to get the info out in case I stumbled onto something that could help someone.
Who knows maybe I got lucky and now some of the amazing brain power around here can work on something else or maybe tonight the gps just likes me.
Someone give it a try and let me know it it helps.
i havent had any problems with getting a lock. i turn the GPS on, then use "GPS test" and usually have 4-5 sats locked in under a min. then in the next 20-30 sec it jumps up to 8-10 sats. i think the problem might be with google maps and not the GPS itself.
That's about how it is working for me now, without having to open gpstest to get the lock. Now I just turn on gps and open google nav.

Just curious but did you turn off gps, drive to a different location, turn on gps and get a lock in less than 30 seconds? If so then maybe you are on to something.

how about a link to the how to or give us some steps to follow...
I have not tested this in different locations yet. I will be driving around a lot tomorrow and will try it in as many different locations as I can.
As far as what I did I followed the instructions for unlocking secret codes here:
Go into the Dialer and enter *#83786633 then press the Home key
Go back into the phone dialer (delete old code )and enter *#22745927
Now a box will come up asking for the SPC code. Enter 000000
Press the Hiddenmenu Enable radio button.
Now you can use these codes.
Then I entered the gps code:
*#1472365#
after that I went to "position mode"
then starting mode
and changed it from hot start to cold start
I was just guessing that if I was cold starting my gps and the software was expecting a hot start that might cause a problem with it gettting a fix before the gps warmed up. I may be wrong in my "logic".
I have several stops between 5 and 20 miles apart and I will turn on gps and google, get a lock, then turn it off do what I have to do. Repeat the test, turn it off drive to the next location and do the same thing. That will give me 2 locks in each location several minutes apart.
I will try to post back sometime tomorrow afternoon about my results.
I hope that will be enough of a test. Should I also turn the phone off and on between tests, not just the gps?

What's more important is, can you turn off GPS, wait several hours, turn it back on and still get a quick fix?
Once my phone knows where the satellites are, I can be anywhere (reasonable of course, not like a bomb shelter) else and get a quick fix. What really slows me down is leaving my GPS off, like 3-4 hours, so it doesn't have up to date data, then test it.
It probably won't lock fast when turned off for a while and in a different location.
You don't actually need the dialer to do this. Long press home screen/shortcut/activities/gpssetup
good to know, that is a lot easier than using the code.
Looks like I didn't fix anything. I woke up and turned the gps on. No lock yet after a couple of minutes.
Yeah don't feel bad dude I did the same thing and got excited
I couldn't even get a lock in gps test this morning had to turn phone off and back on then was almost instant. Not a clue what happened.
It seems that the majority of people have absolutely no GPS issues. But I notice every time that I factory reset, I can't get a GPS lock, which is absolutely weird. I can't acquire location on GenieWidget either initially. If anyone else out there is having GPS issues or Location issues then try this.
How to fix for both:
1. Download GPS Test from the market (the free one)
Run it, and leave it running until the GPS On light turns green and it has satellites in use and tells you the meters accuracy. That means a lock. This can take a few minutes.
After this happens, GPS locks very quickly even after reboots, very weird.
Now even after this, GenieWidget still can't acquire location.
2. Turn on WiFi, but don't connect to anything, you don't have to.
When WiFi is on, go back to the GenieWidget and hit refresh.
It'll find your location even though you're not on a WiFi network.
Now disable WiFi and it'll be able to acquire your location every single time.
Weird stuff.
damn... sounds like Samsung is STILL failing with LBS. It's very frustrating on my Captivate.
I turned it on before and got a fix in about 45 seconds. About the same time as my Slide.

It's a one time issue though it seems. I think actually it all depends on getting that 'first' lock. The phone will go to sleep if you wait on maps too long. So I just use that app, go into settings, and hit Keep Awake then leave it sit til it locks. After that, I can get a lock in 1-5 seconds every time after reboots upon reboots.
It locks just as quick as my Evo, 10-15 seconds for me. I use my GPS so much if its not getting a good lock I would return the damn thing over and over until it work how it should. Even 45 seconds is a stretch...my G1 locks faster than that...

Quite right. There's a big difference between "cold" and "warm" GPS startup.
When the phone is brand new, or after a hard reset, it will always be a "cold" start. The phone has no clue about where it is in the world, or even if it has the correct time. So the very first thing it does is to look around and try to spot any GPS satellites. Then it tries to download the almanac data.
For GPS to lock, quite a lot of data needs to be downloaded from the satellites. This takes between 30-60 seconds uninterrupted view of at least 3 satellites. If you're moving around, the view of the satellites may be interrupted, and the phone will have to start over again. This process can be speeded up a lot with A-GPS.
After the first lock, things go much faster. The almanac data is already on the phone, and the position of the last GPS fix is known.
The thing that confuses most people is that an Android phone will try to navigate by other means when there's no GPS lock. By cell tower, or by WiFi hotspot. Cell tower gives your location instantly, but with a very large margin of error. If your position is way off, then you're not navigating by GPS, but by other, less accurate means.
I actually can't get location from the cell towers >.< But yeah my GPS is locking in 1-5 seconds now.
Still no luck with above... will not turn green just stays yellow
Anyone else having issues getting a GPS lock? I'm sitting inside a building but my Hero would always lock here, especially after resetting the AGPS data with GPS Status program. Tried that with the Shift, and still not getting a lock even after a minute. Not sure what else to try.
Typically I keep mine turned off, but I just turned mine on and went to Maps and it locks my location in.
mine took a little while to initialize (indoors) but it locked in within 30 seconds.
No issues here. Inside my GFs apartment it locks very quick and is probably about 5-10 feet off according to google maps. My moments GPS never locked or worked so I'm extremely happy with the GPS quality on this phone.
The first lock took around a minute to get. Now it gets a solid lock in just a few seconds, if that.
A little off. Not as bad as my gfs Samsung Instinct, but it does often have me a few hundred meters from my actual location.

Me and my girlfriend are having constant problems with the gps lock. Seems to work when it wants and disconnects randomly.

GPS is spotty for me as well. GPS Status won't even get it working for me when it won't work.
When it does work it is not as accurate as my Heroc was. Hopefully this gets some love in any updates.
GPS is great for me. The only issue I've run into is that when I go from Maps to Navigation, my SD card gets mounted as read-only for some reason.
I know a couple of days ago I tried to use my Google Maps/GPS and it couldn't get a lock on me. It was like going crazy or something. However, it was snowing and kinda foggy so maybe that had something to do with it. It worked the next day though when the sky was clear.
No gps lock on my end either. Also tried the gps status clear....nothing so far
EDIT: just opened maps for about a minute or so and it locked finally. Closed maps then opened again, locked within seconds.
Bumping this thread: I have issues with getting a GPS lock. If I open Google Maps, I'll never get a lock (at least not before the phone goes to sleep - 60 seconds). I open up GPS test, which I downloaded from the market. It gets one satellite to lock right away. Sometimes two. Then it takes forever to get 3-4 more (at least 60 seconds). I can then go into google maps, and it will get a lock within 15-20 seconds. But if I let the phone go to sleep, and open up maps again, I don't get a lock, unless I do the GPS test. And sometimes that doesn't even work. I've done the GPS Clear thing, via the epst codes (##GPSCLRX#), and that doesn't seem to do anything. I'm running the MikShiftG 1.1 rom. I'm going to make a nandroid backup, and see if that happens on a stock 2.3.3 rooted rom.
I still notice the gps still takes long to lock in. any suggestions?
Strange, Mines been locking on in no more that 45 seconds, Usually 10 seconds since DJ05...
DLO9 - using leaked 2.2 Rom
My GPS is taking much longer to lock also - i guess its the trade-off for getting 2.2.
The leak 2.2 rom run better than the other Roms I tried.

Odd, mine locks on better than any 2.1 rom and almost instantly.
Oddly enough, got worse on superclean 2.2. With DL09 and superclean (with help from gps status) i was locking within 10-15 seconds, now it takes upwards of 45s-1minute, if it locks at all. A little disappointing, but nothing to make me dump 2.2. Crossing my fingers that it'll get better....
My experience with all 2.2 ROMs so far has been that GPS either locks near-instantly (<15s) or absolutely will not lock at all. It seems to be about a 50/50 crapshoot. If it doesn't work, turning GPS off, waiting a few moments, and then turning it back on and trying again *usually* gets it working.
Granted I haven't tried since jt released the updated recovery, so I'll have to check a few more times and report back.
Try flashing the DJ05 GPS fix that was tested on people with Dl01?
I've long given up on the GPS, I just use my Iphone 3GS that without data connection still locks on really fast.
I tried DL09 when first going to Superclean 1.0. The GPS would lose the signal then regain it. This happened about three times during a hour long route.
Flashed DJ05 last night and tried the GPS again this morning and not once did it lose the signal driving into work.
My gps doesn't WORK AT ALL with DL30 superclean 1.0.
Mine locks in 10 seconds or less running DL30 SuperClean 1.0 with DJ05 radio.
I have been having a problem with GPS on DL30/DL09 also. Here is how I got it to lock today in less than 10 seconds.
1. Download GPS Status from the market.
2. Run GPS Status and let it download the AGPS data.
3. Go into settings>GPS & Sensors>Auto-download AGPS data and set it to never.
4. Close GPS Status and reboot phone with GPS turned on.
5. Once booted, run GPS Status and hopefully you will get almost insta-lock.
6. Open Maps or Navigation and you should be good to go.
Next time you try GPS and it doesnt lock, go back into GPS Status>options>tools>download and manually download the AGPS data then reboot.
Its a pain but its the only way I know of thus far to get "insta-lock" after going Froyo on my phone. I dont use my GPS all that often so this method isnt a big deal for me, but if I relied on GPS daily, I would seriously consider buying a different phone at this point. That or try and get a refurb that has a working GPS like some people here seem to have.

Didn't work for me. installed DJ05 and still nothing :[
Ive had some weird experience with GPS. DI01 My gps was garbage. like 2 mile blue sphere. DJ05 my gps was pretty good... locked accurately but took about 2 minutes. Borked my phone trying to edit some stuff... redid DJ05... GPS didnt work again... did DL09... GPS still didnt work... redid DL09... GPS worked pretty well again... DID DL30... GPS locks nearly instantly and almost perfectly.
It seems like every time I flash I have different results...even when sometimes I'm flashing the same roms from the same sources. I don't really get it... I'm almost in the same areas so it should be consistant.
I always clear all the caches and everything :\
Ive done many different gps tests and here is whats happening...if you try to turn gps on through the notification pulldown...it takes a while. If you turn gps on through settings...location and security...standalone gps...its instant. After turning gps on through settings, it will work from the pulldown every time instantly. Basically it needs to be turned on from settings for the 1st time after a reboot...then the pulldown will be instant. To test this, reboot phone with gps off, when it boots turn gps on from the pulldown...it wont lock...go to settings and turn it off then on...it will lock instantly. Like i said, it seems to need to be turned on through settings initially, then it works instantly any way you use it...hope i helped.
That's strange. I haven't had an issue locking on since DI01. I also love how fantastically loud the Nav directions are now. I agree that gps status can greatly accelerate the locking on process.

daym you!! lol. maybe it's time to go get a replacement?
I couldn't reply in the developers area because I haven't posted enough, but wanted to say thanks to Raptorseye for the following:
"download gps status in market, run it, wait till it locks, then you can use your gps/maps..."
Ever since I moved to Gingerbread I've tried everything to get my GPS to work again with no luck. I've tried the ACS GPS fix, I tried remounting the file system and modifying the permissions, I've tried going back to an ec05 rom, and also swapped out the ec05 modem and ee03 modem.
But by running the gps status application from the market as recommended and letting it sit there for about 8 minutes, it finally locked on to over 5 satellites indoors. I was able to then run other gps apps and they worked.
Unfortunately, you have to repeat the connection to the satellites every once in a while using the gps status app.
There's a setting for gps status to download a gps data every hour if u want it to. In gps status click menu tools manage a gps state. Clear the do it again and click download. But as I said in the settings you can have It download assistance data every day or even every hour. Open gps status push menu settings. Gps and sensors. Then auto- download agps data and set it too what u want.
I too use GPS status, but it does take a long time. For me, the quickest solution is to power down, pull the battery and reboot. Takes less than 8 mins (which might be important if you're trying to get somewhere!) and you'll get a virtually instant lock when you go back to your favorite nav app.
Here's to hoping this gets fixed in GB!

This means you're not getting the ephemeris (Xtra) assistance data on boot, or at least it's not being used.
Are you able to get fixes faster using the Settings -> Update AGPS option in GPS Test? GPS Status has a similar option, but that may crash the GPS if the crash bug hasn't been addressed in EE03.

Does an assistance update from GPS Test help here? Or does only a reboot fix it?
It does not take a reboot to work for me. I just reset a gps then download agps assistance. And close gps status and I lock fast every time. Of course as I said I have it set too download assistance data every hour

The assistance data is supposed to be valid for a whole week, so it shouldn't have to be done more often than that. Although it wouldn't surprise me if it needs to be.
I am curious as to how often folks find themselves needing to update assitance data. Once a day? Once every few hours? Last time we looked into this there wasn't a clear answer.

Hm, never have used GPS Test, but I have it installed now and will give it a shot the next time it gets hung trying to get a lock.
The cold boot wasn't my idea, but I heard it mentioned on here months back. I was getting late for an appointment, so I figured, what the heck, i'd give it a shot. The OP mentioned that the battery-pull method is the only way to really clear the GPS, and I'll be darned if it didn't work. It's solved the problem every time I've run into it. I'll be sure to give GPS Test a run and see what happens.
Thanks!
I have been plagued by the no lock/10 minute lock. GPS status didn't help. None of the patches have helped, in the long run...so I just down loaded GPStest Plus, the newest one, and it seems to do the trick. Instant lock the first time out. Tried again a few hours later and nothing after a few minutes so I reset and redownloaded agps and bam, locked within seconds. Will try again in an hour when I usually would not get a lock or a very, very slow lock and see how it goes.
