For those of us that are not getting better gps on EC01 or various Rom's like me this fix is for you.
Instructions: With Root Explorer (or similar app) go to /etc/gps.conf
In Root Explorer long press on the file and select open in text editor
Change the first line from: NTP_SERVER=north-america.pool.ntp.org to NTP_SERVER=us.pool.ntp.org
Then Download GPS aids from the market and run that for even better results
Save changes and reboot
ENJOY
What exactly is an NTP server, and why would this edit make it more accurate?

I sort of want to try this...
Is there any way this can mess up GPS even more?

I think it might be time to just face the fact that the Fascinate's GPS chip sucks.
Would like to try this, but when i try to open in text editor
in root explorer, it says read-only.
Top center, there's a gray button. click that to go to r/w.
I tried this inside, in the basement while it's storming outside. Haven't turned on GPS all day and it seemed to work. GPS lock w/o Wifi TTFF in 12 seconds. GPS lock w/ Wifi TTFF in 2 seconds (Using GPS AIDS GPS status test).
Time before was around 30 seconds and 10 seconds respectively.
Ahhh of course. Thank you!

I don't think it's the chip, it's how the nav or map app tries to access the information and turns the chip on that's the issue. When I turn on Gmaps, it sometimes sits for a full minute before locking. But sometimes, it takes a second or two. Its got to be because the communication already happened between the app and the reciever.
Here's why this is my opinion. Reboot the phone and start the GPS Test app from the market(sometime within seconds even indoors), watch it find satellites and lock. Usually does it much much faster than maps. After you do this open maps, voila instant position. Theres some kind of issue with how maps initiates the GPS reception on this phone. So I keep GPS Test installed, and when I know I need to know where I am, I turn it on for 5 seconds, then open maps.
If anyone who actually knows what the hell they are doing knows how to edit the commands that Gmaps uses, you could be immortal.
Well wow, gps lock beat me before I even opened up
gps test. Amazing. Thank you!
No luck for me (everything in GPS Test just ramains at '0' or equivalent... no sats even detected!).
north-america.pool.ntp.org seems to have a fair bit higher latency than us.pool.ntp.org, but that shouldn't really make too massive of an impact. This isn't, though, gonna change your GPS from not working at all to suddenly working, just increase the lock speed a bit.
Interesting, I thought that GPS only used the satellite clocks!
GPS has almost always been livable with my Fascinate. I don't know if I am just very lucky, or if it's because I leave it on all the time.

Yeah the fascinate chip does not suck this fix is great even when I reboot my phone still locks great everytime any time you change roms re do this fix

Yeah I know GPS is based on time delays between satellites, not entirely sure how it works so it would make sense that using a different time server might help? Just chiming in so people can hopefully understand what NTP has to do with GPS.

You and i need to knock on wood, I am in the same boat as you. Never had serious issues with it and really worry about that the most when I flash something new...
Tried this with EA28 and EC01, no luck on it for me, my GPS is fairly good, other then it my condo. Just a little frustrating when my Eris worked fine, and my wife's Droid works fine.
This cut the time to lock in half for me. Thanks.
Still not instant but noticeably faster.

Hi there,I'm in mexico celebrating my honeymoon and I'm getting huge waits for gps connection,i can't upgrade to a different rom being away from home,i was wondering if the gps fix had been singled out into one fix update. I've had a search via xda app but can't find much other than whole roms
Sent from my GT-I9100 using XDA Premium App
Try gps status and toolbox from the Market. it donwloads gps assistance data that reduces lock time and gives you more gps info. It might help.
Happy Honeymoon!

Nuno

are you using network assistance to get a gps lock or are you trying to do it without using data? try to get a lock when you are connected to wifi (use wireless network and use gps satellites both checked in settings). next time you go out you should get a faster lock as it will remember roughly where you are
No GPS fix in any rom as no GPS problem reported to Samsung .

My Galaxy S2 has been working great until today. Suddenly Google Maps will not open. I've cleared the cache, data, removed it from the phone rebooted and then reinstalled the application. It starts up, freezes for a moment and then crashes.
The other problem is my phone no longer get's a GPS signal. Before and after rebooting it. I downloaded a GPS tester and it's showing 1 satellite in range, which makes no sense.
My phone is rooted, stock.
Anyone have any ideas? I googled the google maps crashing issue and there's hundreds of threads but no real solutions.
I just uninstalled the Chainfire3D Pro drivers and google maps now opens. Why would those two conflict?
Edit: Still not picking up any satellites.

No. I would like to try to solve the issue before I give up and resort to that.
My old phone used to be able to download the satellite positions to help improve the speed at which it got signal. Does Android have anything like this?

Seems to be working, I will update if I get anywhere. It's at least showing more than one satellite now.
Didn't work.
The only solution was to take out the battery and re-insert it.

Yeah. Use GPS Status and Toolbox.
All of a sudden my phone is taking very long to load a web page if it'll load at all. The load bar will move a little bit and than it'll actually go backwards and just sit there. Even some of my data apps won't open. I've do e several reboots, sometimes it'll be OK but for the most part nothing loads. I did get a security popup when I was reading a DIYS article but I ignored it. I've done a scan but it came up clean...any ideas??

Well I just realized that my girlfriends stock note is doing the same thing, not loading anything. I use my WiFi at home and I've rest my modem and router...still not luck. Some data requires apps seem fine, like the forum and Facebook, took me a few attempts to install an app a few minutes ago. Odd.

A reset of the house modem will help I'm sure, and of course the network may be undergoing a maintenance phase etcetera.
Either way, the report appears to be a service issue, and not device related...g
Perhaps clear the browser cache.
I did everything last night and nothing worked but when I woke up it seemed fine...odd.

Possibly your local cell tower was jambed up somehow, but now ok. It happens.
Hello friends,
I am actually a Sense convert, thanks to the combo of CM10 and AOKP, found in ROMs like JellyBam and PAC Man...
The ONLY thing that's making me unable to use those ROMs as my Daily Driver, is the following issue:
1. Turn on 3G and GPS togther
2. Launch map and choose a place to Navigate to (Navigation is launched)
3. EVERYTHING LOCKS PERFECT! My turn by turn is now ready
4. Give it a minute or two on the road and BOOM! The phone loses signal, 3G is cut off, GPS loses its lock, and I am stranded in the middle of my destination
Give it a minute or two... sometimes minutes on end, and the GPS locks again (after signal is restored and 3G returns), but shortly soon after, the issue repeats itself.
Now, can someone please confirm for me that that is indeed a CM10/AOKP bug and all of you have this issue? Trust me, I have tested it in MANY areas, it's not a weak signal issue. If I only have my 3G on, the connection is RARELY lost (probably with bad signal), but when GPS is used WITH 3G, it's almost UNUSEABLE and dangerous to navigate with, due to the loss of attention from the road and losing your turns ALL THE TIME!
I would appreciate any help on people confirming that I am not alone on this one, and that if you guys know any fixes or workarounds for this? I would love to offer a Logcat even, but personally, I have given up on Devs never willing to do that for the issues I have reported in the past. Not complaining, just saying they are busy or just don't want to help me with Logcats.
Thank you and I hope everyone is well. Appreciate you guys reading the message.
I've been on cm10 for over a month and have never had that problem. I've used navigation for 2 hours straight without a hitch.
Are you on the cm nightlys? I use the irc builds.

Download GPS status and toolbox from the play store. Menu, reset, then you're good. I've had this problem once and it hasn't come back since doing this.

I am suffering from the same issue, it persists for me on all CM10 builds and JellyBAM. I think I did what you said, but the bug did occur again (while using nav, gps and 3g signal goes out for a few minutes). I just wanted to double check what you were suggesting. When you say menu, reset, do you just mean reseting the phone after installing the GPS status and toolbox, or is there a menu option in GPS status and toolbox I'm not seeing?
Thanks,

He means download the app. Open the app. Then hit menu from within the app. Choose reset. Then close the app. Then reboot your phone and try your GPS.

Thanks for the quick response. Maybe I'm being stupid (I hope I am), but I do not see the reset option when I hit menu from within the app. I see Tools, Share, Radar, and Settings. Is it the Tools-> Manage A-GPS state -> Reset?
Thanks again.

Yea I'm thinking that's it. I'm not a 100% sure as I've not had this issue or a need to use the app. However that would seem to be it. If that fails look threw the settings for anything that has the reset option. Also being cautious is never stupid. Hope this helps.

Yes, that was it. How on earth did someone know to do that based on just that symptom?? Why is there no way to do a GPS reset like that via the system menus?
