[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.

I've seen this happen quite a bit recently. I wonder if they backtracked on that really great idea.

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 Issues still...

When I made the switch to android one of the things I was most excited for was google maps and free turn-by-turn. I have tried everything to make this happen on my Fascinate. I upgraded to 2.2 and even tried the GPS Aids app. So my question to you guys is will the GPS ever work properly on this device or is there any other tricks I can try?
Thanks!

Did you update the radio?
My gps work great. Even the voice is much better.

Uh. What issues are you even having? Although I do have some minor issues also. It connects perfect but every few minutes it drop GPS signal for about a minute and then picks it back upnot sure when this happened or how long or what version it started on as I barely ever use it.

I can never get a lock on my location, even after letting it sit for several minutes. It is always in the right area but off with a massive blue circle.

He's got at least VZW location services on due to the massive blue circle, which uses cellular triangulation. Wifi can get you a smaller circle, but doesn't work as well as GPS.
My phone has been totally unable to get a GPS lock for quite a while (since upgrading to EB01 based roms, but even on DI01 and DJ05 it was incredibly pathetic), even with updating the A-GPS data and having VZW & Google location services on.

I have tried all suggested issues. Do you think it is a hardware issue with my phone and I should trade it in or am I still missing something?

Sounds like you might have bad hardware. Since EB01 I just recently realized I didn't even need to have vzw or google locations checked. I get a lock just using stand alone service. 8/11 birdies locked in 18sec with an error of 13ft inside my house with GPS Status. And that was after a full wipe and rom flash.
good day.

Since EB01 happened I've had a near instant lock every single time.

I had the exact same prob. My gps problems have been completely intermittent, sometimes it would lock on and other times it would not. No matter what rom or radio I flash. But this is what seems to work pretty well.
1. Don't use the gps toggle button on the pulldown. Use the settings.
2. Use google maps v4.7 and don't let it update.
Hope this helps...
Sent from my SCH-I500 using XDA App

I've been using the option from the pull down menu with mixed results.
I've started going into the location & security and enabling/disabling gps from their with much much better results.
Thanks for that tip .

With SC 2.4 ROM GPS was working GREAT!!
I updated to SC 2.6 and I cannot get a lock at all.
With Wi-Fi on the best i can do is get my location and the directions. I can only guess that maybe the clock was changed / tweeked in the later versions.
When I get time I will be rolling back to SC 2.4 ROM.

I have determined it is not a hardware issue as someone else in my area is experiencing the same issues. I updated to EB01 and super clean 2.6. My lock is about 50% now. Either the service is great and locks right on or doesn't at all with the massive blue haze. Someone suggested going back to super clean 2.4?
Once again thanks for all the help guys!

this is the key. and one of the main reasons I went back to DL09 on my phone until the next build comes out.
if you turn it on in settings-->location&security it will work, and then you can turn it off/on via the notification bar for a while, until you reboot your phone...

Is it google navigation having the issue?
I continue to play around with this issue, and am noticing people talking about still being able to be picked up through GPS tools, but not get locked elsewhere. I am assuming that, like me, they are referring to google navigator giving the message "Searching for GPS". Oddly enough, Google latitude is accurately showing my location even when google navigator is telling me it is "Searching for GPS" and drops my turn by turn instructions. I saw one post from cableguy1 to use google maps 4.7 and disable updates, which I would be interested in trying. Anyone know where I can get v4.7?
*Never mind. Didn't pay attention to the fact that my Wifi was on, and the location was a couple houses off. It simply looked precise in comparison to the big blue circle I'd seen while driving. Sorry for the misinformation.*

SC2.4 doesn't have any locking issues for my wife. Good to go there, but not sure if we're just lucky.

2.4 working well
After finding a couple other threads addressing GPS issues, I've noticed people with sc2.4 to have the least problems. Flashed the AIO Odin version, and have had an instant lock so far all morning. Very nice to have google navigaion back

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?

After Flashing to Overcome 1.2.1....GPS is not working correctly.

Ever since I flashed to Overcome 1.2.1 the GPS has been VERY wonky and just plain WRONG. Maps says that I am in the next TOWN which is a good ways away.
GPS Locks are extremely few as well and takes forever to lock on to.
Can anyone else confirm this and or help?

Bumping this up.

When you flashed, did you wipe your cache? With a new rom it always takes a while to reaquire your location. I use the app HereIAm2 from the market to get that first position lock after a rom flash.

Yes I did wipe the caches. Will try that app out if it is free.
Thanks.
EDIT: Noticed that the compass seems to be very inaccurate as well. Weird.

Oh well, that's the least of my probs;-/
i have installed OC 1.2.1 and at one point the whole tab became very sluggish....and all sort of issues appeared such as slow browsing.......then the tab would simply freeze! Reboot did not help at all....
I have since installed OC 1.2.3 with the new kernel and it went ok-ish. But today after rebooting i have all sort of errors (broken messaging service, when i click on the wifi tab to switch on, it says 'error'.etc).
I wonder if others have this sort of probs. I cannot understand how it can work fine for a few hours and then.....kkkkkkkk.
I have the UK tab version with firmware JK5; Also cannot figure it out why it does not show 'overcome v1.2.3 on the build number...it still shows v1.2.1, kernel overcome 97.
I'll have to reflash the lot now.......how annoying.

I am sorry that you are having problems. However hijacking threads is frowned upon here.....

The app is free.
How many roms have you flashed? Maybe it's time to do a factory reset, then flash the full version of the rom/kernal.

Well it did the trick and put me in the correct spot but the compass is still completely wonky.
Oh and this is the first ROM I have flashed. Overcome 1.2.1.

There are apps in the market for that. You want to calibrate the compass, so look for a gps utility. Sorry I don't have one to recommend to you.

Not a problem. I appreciate your advice and welcome any others as well.

One thought about the compass - do you have your tab in a case with a magnetic clip?
Mine works fine out of the leather case, but not when it is in the case.
Just a thought.

No I don't.
To test the GPS to see if there was any interference I put my iPhone 4 into compass mode in maps and did the same with the Tab using the Maps program.
The iPhone 4 was spot on....however the Tab was wrong yet again.
So that means there is no interference.
I am stumped here....and the recalibrate apps did not work either.

Just thought I would try a catch-up.
Since my last comment I moved from Rotos JMIv2 to Overcome 1.2.3 and my GPS also stopped. After 24 hours however, I have got it going through a the use of GPS Status (free from the market) and the LbsTestMode which you can access either through a dialler code or through SGS Toolbox, also free from the market.
To cut the story short, I went from just finding about 3 satelites (with no connectoins), to finding and connecting 10 satelites.
I must say that I am very happy with the current ROM and with the GPS Status program.
Hope this helps if you are still having problems.

GPS cannot lock on signal on Trigger 3.2

Hi guys,
I've installed Trigger 3.2 and flashed the S.GPS fix, im trying to use the GPS using the "NAVIGATION" app but it wont lock on signal... it keeps showing me this "сhecking navigation availability" message while the gps icon on tray keeps flashing...
i left it a coupe of times for half an hour but it still wont lock on signal...
the starnge thing is i tested it using "GPS TEST" app and the apps shows that the GPS DO work and it allready found 12 birds and is using like 8 right now...
what do you guys think could be the problem?...

I just tried it on trigger 3.3 beta. At first it did as your saying. I reflashed the s.zip fix, went to gps test after reboot got a good lock. Then ran navigation no problem.
When I was still stock gps test was the only way I could get mine to work. So its habit for me to use it to get a lock then go about maps/navigation.
Dunno might work might not.

The fix does it itself. No need to do it manually.

Same problem. Ether way the GPS on the Vibrant sucks monkey balls. Horrible compared to other android devices! And there is not a good fix for that! Tried about 20 Roms and GPS still sucks even tried 4 Vibrants devices. Sh*t out of luck! Nice screen but crappy GPS.

I don't know what they do over there but it sure works.. I need to find out what are they fixes and see if they are able to work on my Vibrant or not.
Seriously GPS lock in a few seconds for Galaxy S device is just simply magic. Let me know if anyone know what they did on that rom that make it sooo much better.
