Enough satellites but no fix

Hello all,
I am using Froyo XXJPO on my Galasy I9000. My problem is, that I cant get a GPS fix. But I can see 9 satellites if I use a GPS test tool.
Any idea what I can try? Thank you.

Well this is a first, someone having a gps problem.....you tried any of the million suggestions already posted?

While it's true that GPS problem has been discussed at lengths, people normally complain about poor accuracy and intermittent fix.
OP here is talking about another problem which I now experience myself since upgrading to Froyo. Quite often, SGS sees plenty satellites with SNR above 30, but just doesn't use them. At the same time and place my friend's Nexus sees less satellites but gets a fast and sure fix with them. This seems to be a driver problem in Froyo, not a hardware issue.
Edit: Forgot to mention that SGS usually gets the fix eventually, it just takes up to 15 minutes sometimes.

No fix issues have been done to death as well. Normally sorted by dicking around with your supl settings in the hidden menu.
Gps is just ****e on this thing, hope one of the solutions works for you.

Get GPS Status (from the market)
Reset and redownload A-Gps from the menu (menu, tools, Manage A-GPS State)

It was the first thing I tried as soon as this issue appeared.
Doesn't make much difference if any.
By the way, on Eclair GPS worked just great for me (with JM7, that is. Before JM7 it barely worked at all).

I got the exact same issue, I can see like 8-10 sattelites with plenty of +30db and can't get a fix. My TomTom gps from 3 years old only sees 4-5 but gets instant fix.
Before I was on JP2 and this didn't happen > it fixed fast and sees the same amount of sats.
However, I must say that accuracy is great, when I do get a fix, accuracy goes up to 16 feet within the minute ands stays that way.

can you look into the LBS settings and tell me what is the accuracy used?

In my first tool I have written something about "GPS test tool". This GPS test tool is GPS Status. If I download A GPS data again make no chenges. Just a lot of satellites wihtout fix.

Well, to both
LBS Menu: *#*#1472365#*#*
Standalone + "Hot Start" + Accuracy More than 15 + "Automatic" in SUPL settings.

Actually, it's now *#3214789650# (since Froyo or late Eclair ROMs)
I'm using accuracy 30 now. Was testing it with 50 some time ago with no noticeable difference.

Weird, and it was working before right?
Have you hard reseted the device prior and after the rom upgrade and cleared the caches?

when i try to access this LBS menu in froyo i hit the final * key then it all disappears and no menu pops up.....
What am i doing wrong?

Same problem here.
GPS was great and dead-on accurate on 2.1 (O2 UK official firmware) and now it rubbish (O2 official froyo).
This is not a hardware issue.

same problem here, just that there are no values in gps test (time is always 00:00 as well as all others and the compass is jumping back and forth.. the day before yesterday before i've had used faster fix it worked great =( ) anyone knows how to fix without reflashing?

Weird, I got the exact same firmware as a collegue and he gets a fix way faster than me, he even sees sats inside our officebuilding (I see none).
However, using the 3214789650 code and doing the Get Position test, he gets a weird orange text where I just get regular information.

[FIX]GPS Dropout Fix

If you're having problems with your GPS continually dropping out, particularly on the new Gingerbread release, try downloading GPS Status from the App Market and reset your AGPS data.
In GPS Status,
hit [Menu],
then [Tools],
[Manage A-GPS state],
[Reset],
Optionally you can [Download] for new A-GPS data
I tried it on CM7 nightly 36 and apparently I'm getting quicker locks.
[Update 01]
Apparently, that first method works for some, but not all. There is a second method, but it requires you to be on a Sense Rom (Stock HTC based). I'll add it here. More people say that this works better, but I was reluctant since I was already on an AOSP Rom (CM7), so I would have to flash back to a Sense Rom.
You will need your MSL code for your phone
Using a Sense Rom,
go into the Phone Dialer,
and Dial ##GPSCLRX# (##4772579#)
(Reboot)
Here is the original post by SantinoInc: GPS Fix (GPS Reset)

Were you driving? That has been stated numerous times to only work while not moving. Or to only work for a short period. I did the ##GPSCLRX# fix and have not had to worry since. Getting down to 6m accurate whole driving.

Please forgive my ignorance, but how do you type letters on the dialer? I tried using the number key with those letters (works out to ##4772579#) which didn't work. So I feel appropriately humbled. How does one run that code, please?
GPS Status works fine, but I only use it for this; so, if I can not have another app on my phone that would be great.
Thank you for your time.

I was also having GPS problems with the CM7 ROMs. I restored a Sense ROM and ran the fix using the dialer, then restored my CM7 ROM and my GPS worked perfectly. However, I just flashed to the lated MIUI ROM and now my GPS is taking a long time to lock. Had maps open for 10min on my drive into work before it locked on. It did eventaully lock but it doesn't seem to work as well as it use to. Wondering if this is a MIUI thing??

Im in Japan on a seasonal stanby for three months
so i dont have service, just paying 9$ a month
Im trying the ##GPSCLRX# on a sense rom so i can switch over to a 2.3.3 rom
I put in my MSL and did the reboot
i opened maps and have been waiting for around 30 mins for a lock
and NOOO success
It just will not lock!
Is it because im on Seasonal standby?? and not using phone service
My GPS is on and im using wireless networks turned on
its still moving around not locking
ahhhh!!!

My gps would not lock and the icon would just disappear after a few minutes. I was able to get it to lock using the steps for 'GPS Status' app, but I had to do it again the next day. But after closing out of all the apps, the gps icon was still there and would not go away.

There was no need to start another thread on the GPS fix; it's been posted for quite awhile now.

No, even from Japan with no service you should be able to get a lock. In fact you should be able to get a lock from anywhere with NO data at all, but you do need a data connection to download the map data and see a map overlay of where you are (obviously), and also you need data in order to download the GPS "cheat sheet" A-GPS data. But it sounds like you have other problems, perhaps your ##GPSCLRX# code didn't take. Did you reboot all the way through? try it three times in a row and make sure that you do NOT use any app that can access the GPS device after the last reset before flashing an AOSP rom. That includes the market, the web browser, maps, latitude, navigation, etc. After the second time you reset it, try shutting it off entirely in the control panels.

GPS fixed on CM7
Hello,
I tried everything said in forums about gps fix but I had no gps on CM7 nightly and had no problems in sense roms. I do not remember where I found someone recommending a kernel for gps fix and another people said ##GPSCLRX# solution should be apply 3 times in a row to be effective, so I tried both, I have gps working perfect on CM7 but I cannot say which method was the solution.
This is what I did:
- Made a backup, of course.
- In Ginger-AleV2 (sense rom) I dialed ##GPSCLRX#, then enter my MSL, reboot automatically. Returning from boot I repeated this step other 2 times.
- Go to recovery (I have Amon-RA 2.3) and restored my CM7 nightly #86, then I flashed #87 (in same session, just wipe cache & dalvik before), then flashed GoDm0de-v8 kernel (in same session too).
- Reboot and checked GPS, working perfect since more than 8 hours.

after you do the gpsclrx command and it reboots you NEED to open the google maps or similar software, let it lock and track for a few minutes, then reboot and nandroid back to cm7

Just for giggles, leave your GPS on when you flash CM7. That was what finally worked for me.

GPS fix CM7 DHD

After endless searching for the gps solution i've found a solution.
I've tested it and can confirm it works.
All credits go to the developer of faster fix (Bernard Bekker)
So here are the steps:
1. Download the CM7 rom ( I'm currently running the built #15 nightly)
link:http://mirror.teamdouche.net/?device=ace
2. After installing the rom and gapps set it up as you normally would.
3. Download Fast Reboot from the market (and install it).
4. After installing the Fast Reboot, download Faster Fix from the market (and install it).
5. Now turn off the gps (not in the notification bar, but in settings).
menu/settings/location
6. Run Fast Reboot
7. Run Faster Fix, and select your country and hit Go
A pop up should say: for example "Done set to:nl.pool.ntp.org" as I live in the Netherlands.
8. Turn on your GPS and reboot.
Now when you use the Google Navigation you should have a fast and steady fix for your GPS.
This won't work if you turn off GPS and on again.
In this case you have to reboot your phone!!! Remember to turn on the GPS bevore you reboot your phone!
It is not nessesery to repeat steps 1 to 7, just 8.

Just tried this and got instant GPS lock when I walked outside of my office. THanks for posting this.

Seems to work. Thanks for the information.

Maybe I am doing something wrong but I just followed these instructions and when I rebooted the phone froze on the splash screen. Had to recover and flash my nand. Have you heard of this problem?

No, i never had this problem, mostly if you make a lot of changes, reboot in to recovery and flash a .zip and than reboot, you might end up with a bootloop in the splash screen.

Just to inform you guys, if you are using a gel case on your Desire HD, it's going to have a noticeable impact on the GPS lock time, from two minutes down to only several seconds.
I have confirmed this with my Case-Mate Gelli, and there is also a video by someone else on YouTube showing this.
http://www.youtube.com/watch?v=bUyhxm2NtDU&feature=youtube_gdata_player
Faster Fix will still help with the lock time in both cases, so thanks to the original poster.

Unfortunately, it didn't work for me. I have an HTC Desire CDMA from USCC with CM7 RC4 running.

?permanent fix
It worked but is it a permanent fix or every time you want to you GPS do u have to turn it on then reboot to get it working again? Thanks

Evo4g / Sprint, worked pefect (saved me from a lot of reflashing)!
Tnx

I still find the GPS to be very poor on my DHD. updated the radio, applied this fix and it still takes a long time to lock, even when outside. Its almost as if agps isn't working at all.

Just a thing to test
Menu>settings>applications>development
Make sure "Allow mock locations" isn't checked
I suffered with terrible GPS reception for weeks until I noticed this was checked. Now I get on average 3-7 yards accuracy, fixing in about 3 seconds

Also didnt work for me. Have flashed a few different Radios and ROM's, does anyone know a highly recommended Radio for CM7 and gps? (preferably on UK Orange if that matters / makes a difference to gps).

Worked well for me! Got an instant lock in my house after doing it. Used to take about 2 minutes outside. Cheers

Hello!
What is in the gapps file and how do you install them?
Is it possible to use them with another rom or is they locket to CM7HD?
For the moment I am on RCmixHD.

GPS is not even locked while iphone did that within 3 sec

Dear users ,
as i told , i have a big problem with the GPS it take LOOOOOONG time to fix
i did google the problem thy advice to tried *#*#1472365#*#* and *#*#3214789650#*#* but nothing happens when i type the numbers
is it software or hardware ! and what is the fix

The answer is all over the forums. But some more information about your device would be helpfull. Ill assume that you are running a stock ROM. Many people have had great success fixing the GPS by flashing to XXKG6 firmware. That worked for me. Give it a go.

sometimes i can get a lock in 30 seconds and sometimes it take 5 mins and that`s with a clear sky, and i have tried must of the gps test apps with downloaded assistance data.

What version firmware version are you running? Do you have a custom ROM installed? Rooted? I to had the exact same issue with my phone. I was running the stock Bell ROM from Canada. Firmware was MUGKG2 standard on Bell/Virgin Phone. I rooted my phone with CF roots available for KG2 and had used all the GPS data tools that I could find. Then I flashed my phone with Cognition ROM which is using XXKG6 and BOOM GPS working. I found all this on this very forum. I will search and and post it for those who cant find it.

In order to get the most help possible instead of saying not work, why don't you say what you tried to do, what happened when you tried, and then say it didn't work. That way you can get the most help as possible.

Update your firmware to a newer version.

I did install :
GPS Status app and the Faster Fix app.
point Faster Fix app to Asia.
restart the phone
open the "GPS Status" and open google maps !
still the locator blinking for more than 30 min !

Try updating your firmware. As i stated I tried everything as well. It wasnt until I updated the firmware did I get consistant GPS connections.

Mine locks within 5 secs without any firmware change, a Galaxy S II right out of the box. Maybe you're in a place without much satellites or you're indoors? Or maybe there's a malfunction with your network an A-GPS.

Hi I had the same problem - GPS could see plenty of satellites but would not get a "fix".
I then rebooted the phone and then within a few sec it could get a fix even indoor.
So try to reboot.

Atrix - GPS Problems!!!

Hi guys,
I'm totally confused and frustrated.
I used Runkeeper on my first Atrix succesfully for 6-months - the Atrix then died and I had it replaced. The new Atrix still worked brilliantly, getting a GPS lock almost immediately, but over the last month or so, the CPS seems to be all over the shop.
It takes an age to lock on and then the accuracy has dropped off.
couple of thoughts:
1) I use Google Latitude, it also worked flawlessly on my first Atrix, but the new Atrix didn't update my position on Latitude anywhere near as well as the first Atrix from day one.
2) I installed the Great Land Grab and also MapMyRide a few weeks ago - these worked really well first of all, but in the last month have been rubbish - not seeming to get a GPS position without endless rebooting and restarting of Apps etc.
3 Using GPS status - if I stand in a middle of a field, reset the datat and download new data - the quickest I can get a GPS fix recently has been circa 50 seconds - I've no idea what the time was before this all started happening.
Is there anything else I can do other than reformat the phone (I've already removed MapMy ride and several other fringe apps that I thought may have had a gingerbread issue or similar)
Cheers
Wilf

If this is a question then use Q&A section and if its not then plz give little more info like ROM, Kernel, Bootloader (locked or unlocked) and finally plz dont take this the wrong way but have u used the search option of xda-developers. Trust me its free and fast and if u use it correctly ull find out that almost 95% of the problems u might have are already addressed.

Start reading up on the different radios available for the Atrix. I have read some since my gps takes a while to lock on too. Reports of increased gps fixed times seem to be rampant if you find the right radio for you.

I had exactly the same problem and solved with flashing 36p radio. Now GPS lock is in few seconds with all satellite visible and accuracy is great.

Original uploader made it private for some reason. I uploaded it again on my account: http://www.mediafire.com/?7y8k6f6797bw3bf
In my previously post you can find link for servers where is hosted a lot of radio and other files. Currently is down.

I did exactly what Zeljko1234 said and I will test out the 36p baseband on my lunch break with GPS Status and see how long it takes. This morning in my car it took 143 seconds.

37P did the trick. GPS lock in like 6s or less all the time now.

36p vs 37p
I'm using baseband 36p currently and the gps has worked flawlessly, my girlfriend has an unrooted atrix which is on 37p and was having major issues with finding location on maps, so I figured maybe is was the baseband. I switched my rooted atrix over to 37p and didn't have any problems with GPS either. Then she insisted it has to be a hardware problem, I figured "user error" was more likely, but instead of pointing that out I wiped her data on maps and BAM! her location updated for the first time in 5 weeks.

How did you wipe the data?
And which data exactly?
Is baseband 36 or 37 better for GPS ?
What's the best one?

I just went into manage apps and cleared data for maps in there. I have been using 36, but they both seem very stable.
