Bad GPS lock with WIFI off.

My GPS stopped doing accurate readings when i flash roms with the ziggy gps fix. the only way that it gets accurate(within 20m) is with wifi on and connected, if its off it says accurate within 3700m. Thats not too accurate if i might say, anyone else having this problem/ found a fix for it?

Check the following thread:

I've done that, and it knocks my gps off completely. Any clue why its attached to Google location services?

Interesting, I attempted the same thing and I am unable to get a lock when I disable the Google Location Services.
I'm running on Das BAMF 1.3.2 with the kernel update 3a which includes gps fix/enhancement from Ziggy.
I've been testing how quick I get locks when using the Navigation and I am still seeing a considerable amount of time before it finds a GPS signal. I've also used GPS Status from the Market to reset and download GPS data but I haven't really seen a difference.

Used this method and Ziggy's GPS mod and I get a lock within seconds as opposed to 10 minutes. If I turn on Google Services it goes back to a 10 minute lock time so I think it has more to do w/ the Google Services rather than modifying the GPS Config through Root Explorer.
Edit: I will add that initially my phone will say "GPS Location is Currently Unavailable" and 2 seconds later it gets the GPS lock /shrug

Well mine stays searching when the Google location is off, never gets a signal. What is the stock gps server so I can switch it back?

Well I just found that as long as WiFi is toggled on, the gps will lock on no matter if there's a connection or not. Tied into he WiFi somehow?

That is odd that WiFi affects the GPS locking. I'm trying to find anything I can on this. "Searching for GPS..." in Navigation is annoying as heck.

I also had a sneaking suspicion that toggling wifi on and off caused gps lock issues, I was using another rom at the time, but for some reason, all of those problems ceased when I flashed TeslaCoil and completed the gps conf fix.
Not withstanding, gps should lock quickly using only stand alone, and right now, my gps works splendidly

Where can I find that gps conf fix at? I wanna give that a shot.

You can grab it here:
Improve GPS lock - credit Ziggy471
It edits the gps.conf so the NTP_SERVER=us.pool.ntp.org

That comes default on the roms I use tho. Still attached to WiFi switch. What's the closest lock you can get with your gps?

i was having GPS issues with the last two bamf kernels. google maps seemed to lock onto my location after a few seconds or a minute, but other apps that tried to use the GPS would never lock on. i noticed when you go into google mapls, the GPS icon/animation appears on the status bar.
the GPS icon would never appear for other apps that tried to use GPS when using the bamf kernels.
with the stock TB kernel, all is well.

Ok, gps is definitely tied in to WiFi. Without WiFi on its 3400m away and with it on is within 20-50m. That only happened with the ziggy fix so maybe if anyone could show me the original settings for the stock gps server file I could change back and forth and test what the problem is.

So I rewrote the gps.conf back to the original north-america setting and that fixed the problem. Any clue why ziggys rewrite of a word in that setting would mess it up so much? And how is it ppl are supposedly getting improvements with that, like what exactly?
Sent from my ADR6400L using XDA App

I don't know what the rhyme or reason would be for this gps issue, because it's so random, there is no pattern to this mess:
1. Got the phone, gps worked great.
2. Rooted phone, still worked great.
3. Flashed first rom, Virus to be exact, still worked great.
4. Several days later, with no rhyme or reason, I noticed that Cardio Trainer had not picked up location
5. Factory reset, problem still persisted, could not lock on to any birds, confirmed with gps test app.
6. Flashed CWR of stock rom post root, still not working.
7. Flashed RUU stock from fastboot, working again perfectly.
8. Have flashed 2 non stock roms since, BAMF 1.3.1 and first TeslaCoil (current) and gps still working perfectly
I can't think of what could have possibly caused this, but now that gps has been stable for about one week and I haven't been using wifi, over the weekend I'm going to toggle between wifi and 3g and see if it causes any issues.

I'll be trying the new Das BAMF 1.4 to see how it behaves. Wish me luck!

Joanni, I'm having the exact same issue that you've been having. With Google services on, I get the wide area. If I turn it off, I get nothing. The only way I get a lock is with WiFi on. I'm currently running Virus ROM.
I know enough to be dangerous when it comes to digging into my phone. I generally just follow well polished instructions. How would one go about trying your fix?

Joanni just edited the gps.conf file to read NTP_SERVER=north-america.pool.ntp.org
That was the original setting. It has been said that changing the setting to us.pool.ntp.org has fixed peoples GPS locking issues but in my testing I found no benefit either way. What I have found, is that turning WiFi on will enable the GPS to have better accuracy in finding your location (20 meters to 50 meters in my case). This is exactly what the popup says, the first time you launch Google Maps.
If you wanted to check what your gps.conf file has set as the server, you can use Root Explorer and browse to /etc/gps.conf
There is also an app in the Market called FasterFix that will change the server to north-america.pool.ntp.org for you.

Problems with GPS

Hey guys, i had a question, and forgive me mod's if there is already a thread for this. Let me know and i'll post in there. But i was wondering if anyone else was having this problem. My shift's gps is not working, nor has it since i got it about a month ago. I've tried everything from downloading gps toolbox, to trying to to update the gpsone tab in qpst. Now, when i go to enter in the server ip address in gps, and the other settings, i write them to the phone, try turning on gps toolbox, standing in one place for 5 or so mins, nothing, not one damn satelite. I go back into qpst, and all my settings in gpsone tab are gone. Wtf? Anyone having this same problem?

When you flash a rom, do you first thing connect up to your wifi before you sign in to your google account?

In GPS settings turn on "Use wireless networks". Problem solved.

I figured out GPS for the most part. Please read my earlier post:

2) After spending lots of time on GPS I found that getting the first lock is the most important thing and then it just works.
As of this time my opinion on GPS is that I am still unsure as to whether or not fasterfix changes anything but wireless assistance is definitely needed to get a good first lock and is used by some apps in acquiring location.
If you don't get more than 2 satellites in GPS status and it takes a long time to get those 2 satellites GPS hasn't gotten it's proper first lock yet.
This has nothing to do with having the GPS getting a lock in sense. It seems the GPS needs to use wireless assistance first to get the lock (contact sprint servers or something) and then it works pretty well. Still experimenting to figure out how exactly the GPS works and what the optimal settings are for it.

So yeah, try fasterfix and set to north america NTP Server and then in GPS status hit the menu button -> tools -> reset AGPS data and then menu tools -> download gps assistance data

Haha no problem and good luck! Make sure you keep us updated! GPS has frustrated the heck out of me for the past month. That's the best I can come up with at this point. Need to have wireless assistance on and the first time you boot the phone on any rom you should be outside and get a good lock with a clear view of the sky. After that it's good to go.

So, should I flash my rom again? and avoid setting up google account, then run the apps?

No just go to GPS settings, turn on use wireless networks, use faster fix, then open maps and try and get your location while outside and with a clear view of the sky. The GPS icon will stop flashing in the status bar when it has a lock. It will stay in the status bar as a solid icon, meaning that it is locked.
Then run GPS status and see how many satellites you get. You should get at least 4-5+ (up to 9) when GPS is working properly.

No longer than 30 seconds if you have good reception.

Spoke with OP via IRC, he is flashed on Metro PCS. Seems like he isn't flashed properly and also doesn't have MMS working. If anyone has any Metro PCS knowledge please feel free to chime in.

wtf is wrong with my gps---- it thinks im in nevada

Guys , i have done the flash for the GPS fix like 3 times...I have wiped my phone clean , and did a fresh install of ics 2 times. It still thinks I'm in Mesquite nevada. I'm in FT LAUDERDALE FL... help!!!!!
Has anyone fixed this?

My GPS is acting the same way eversince I updated to ICS.
GPS takes long time to lock. My advice is to turn on Location Services as well as GPS.
It's funny that Maps don't work but if you switch to Navigation, it works fine (after a long wait).

I don't want to use wifi to find me. I want to use the gps. This sucks the big one..

Clear data and cache from maps. Clear data from google services frameworks. If that doesn't fix it try GPS Aids from market. It has a GPS doctor button that has fixed this problem on my old phone.

This. The problem stopped entirely once I deleted Maps and started using alternative mapping apps instead.

2 things to try... I had TERRRRIBLE gps status on cm10 when, and the agps fix didnt really change it (it said I was in Africa)
make sure that in the location settings you have: use internal gps selected.
and install gps status from the play store.
open it> press menu>> select mangae agps state>>> select download>>>> then reset
reboot

I've been lazy with the AGPS patches so I've been using FasterFix:
https://play.google.com/store/apps/details?id=com.Double.FasterFix&hl=en
I still get 3-5m accuracy.

Ya the agps patches only worked for me once. I remember on gb GPS was amazing. It kinda sucks not being able to use my phone for a GPS now

I've been reading up and there seems to be no fix for it on stock 4.0.4. I may just go to the att store and tell them to give me a new phone whose GPS actually works.

sorry gor my english. :silly:

Nope.... the problem is it can't find any satellites....
And i want offline gps works. not online AGPS.
tried this one twice but still my gps can't find any satellites

I am in the same situation. My GPS used to work and then it stopped. I can't even remember what I flashed or whether it stopped straight after rooting.
I've tried a whole lot of different ROMs (JB/ICS/GB, AOSP/Sense) so its not a ROM issue. I've used the AGPS patch and all those other GPS apps that are supposed to diagnose and fix the GPS, non have worked. I have eventually put it down to a hardware fault and conceded that my GPS will not work.
I'm not wondering about flashing another radio. Will that make any difference ?

No, radio has nothing to do with GPS. If it's faulty - it might just be a disconnected antenna.

Enable data
I know its not the perfect solution but by enabling mobile data and the GPS you do get a precise fix on your location and it barely drains your allowance.

Mobile data doesn't affect GPS. All it does - it enables downloading almanac and ephemeris (satellite path charts, that tell the GPS where to look and for which satellites) instantly from the dedicated internet servers, and it also allows more precise clock synchronization - all that to make the lock faster. It doesn't help maintaining the lock.
And even without mobile data, at least 1-2 satellites should be visible almost immediately.

GPS won't lock anymore

It can get my location but never locks on. Its always like 100 meter range or so. Can't do turn by turn nav. And it can't really find me while driving. GPS lock apps never lock on but it does see satelittes. What can I do to get it to lock again. I see this on cm or touchwiz/stock ROMs. Please and thank you

I recommend getting from the play store GPS STATUS & TOOLBOX then after running the app go to the menu and select "Manage A-GPS state". It will wipe all cache gps data and download assistant data to speed up your gps lock. It has help my gps issues across various phones and ROMs. Well worth the price if you want to get the pro version.

ive tried every gps fix/lock app i could find. none of them work.
i am going to try flashing back to stock through odin and running a sensor test to make sure the hardware is even working correctly.

which rom are you on?
if you are on 7.1, there is a gps fix you will need to flash in recovery.
