Why does my GPS STILL not work? - Fascinate General

Loving the phone and the community here, but I'm starting to get frustrated with this thing. Before DL09, I could never get a lock. After updating to it (manually, before it was an ota), my gps worked for the first time ever. However after switching to DL30 and subsequently EB01, I can no longer achieve a lock. I thought this fix was already taken care of? How come the newer radios aren't working on my phone?
I'm currently using the EB01 radio on Superclean 2.4

You turned on all of the GPS settings (Google, verizon, standalone) and cannot get a lock?
Im getting a lock on EB01 way faster than DL09.

I'm on super clean 2.2 and I have no issues with GPS. Have you considered that your phone's GPS may be faulty? I'd exchange it.

I leave the GPS on all the time. In most buildings it keeps the lock. I really hope that leaving it on makes it easier to live with.

In my foray into EB01, GPS was flawless... for a day. After that I couldn't get a lock to save my life, rebooting clearing stats etc.
The difference was four friends came in from out of town with GSM android phones. We all were having issues. It is like they were kryptonite.
Of course it is ridiculous to think that one GPS would mess up another since they are passive devices. I would advise taking this as weak entertainment or with a grain of salt. DL09 is back yup normal, usually 10 seconds sometimes two minutes for a lock.
In my opinion, getting stable froyo on these units won't be so easy, and I hope we get a few timely releases until they get it right. If EB01 does go OTA, I am screaming bloody murder the moment my clock goes out of synch.
Swyped w/ XDA App. When in doubt, mumble.

try turning on your wifi network (even if your not on a wifi network) this gives you a pretty good position.

For positioning, I just use the cell towers. That's fine. Its for turn-by-turn directions where I really want the GPS lock.

After 48 hours or so of uptime my GPS is definitely not as quick to fix as it was under DL09. I'm sitting in my favorite armchair looking at a fix with three satellites whereas I used to get a fix with 7 or 8 and an accuracy of 8 feet. After a reboot my fix time drops to about 15 seconds and I get a lock on 8 satellites.

these have been my experiences with Super Clean 2.x (voodoo and nonvoodoo):
- sometimes turning the GPS off from notification window and back on again will do the trick
- sometimes when the above doesn't work, turning it off and then back on again from within settings (where you need to click "agree") will be more effective. In this case I've even noticed a difference between doing this by going directly into settings vs. letting Google Nav tell me that GPS is disabled, and agreeing to let it take me to the location settings.
- bizarrely, sometimes opening "GPS Test" app (market, free) identifies satellites more immediately than Google Navigation. Then after GPS Test can see them, I go back into Google Nav and it will see the satellites right away.
- if all else fails rebooting the phone has always done it (and then doing the same dance described above)
Don't get me wrong I wish it were more stable/reliable but the above seems to do the trick. When it locks at all - it locks right away. I have just forced myself to make sure that the GPS is working before leaving the driveway, or else I run the risk of being frustrated when I need to make a snap decision to go somewhere that requires navigational aid. For me it's almost as if the Android OS isn't properly wrapping its arms around the GPS hardware than an issue of the apps locking a fix.
Last night I almost missed a flight and even went as far as to say "I really need to start bringing my old GPS around with me again". I really hope to avoid this.

DII8 - back to GPS issues.

Anyone having major GPS issues? Seems like it was worse than before. Took forever to get a lock while I was driving, had to stop and turn off GPS/back out of Google Nav, go back in. It got a signal for about 10s then lost it.. with full bars. Anyone else having this problem?
Mine still doesn't work at all. -_-
No problems here ... I usually have it off but whenever I need it, I've always gotten a lock immediately and flawless navigation using Google Maps. Absolutely destroys battery though
Took me 15 min to get a lock on a clear day outside on a fresh reboot and still was off on my location. My touch pro 2 never had this problem.. I could use it inside a building full of metal and still get a lock.. I love the Epic but I would not use the gps in its current state of function for navigation purposes..

I think for many, it's still having problems on cold boots. Once it locks, it seems to be fine. I never experienced this though, I only have problems getting GPS signal inside buildings.

No the opposite is true, the problem people are reporting, including those above, are on warm starts where, on occasion, old expired ephemris data is in cache and causes problem getting a lock in otherwise good conditions.
This is much tested and there is a good workaround. By setting the Epic to cold start you overcome this problem, it is stickied as the workaround on the large epic forums elsewhere:
Enter GPS debug/settings application by typing *#1472365#
click "Setup" tab
click "position mode"
Click "starting mode
Enable "Cold Start"
Back out.
Whats the difference between warm start and hot start
mine shows me and my wife in texas half the time and we live in florida, never did it before this update. seems to be picking it up from the wifi I use in my house, as thats ATT and they are SBC and i believe they are in texas, but i never rehooked her phone up to wifi and lattitude shows her in texas at different times and the thing shows me in texas as well, its like cell triangulation doesn't work worth a damn.

^ Same for me. Never an issue and even locks indoors. Yes it eats batteries for lunch though.

The GPS is worthless and can not be relied on. Yes, on occasion it does work and on that rare occasion, it seems to work well. However, on the five occasions that I have NEEDED it, it has failed me completely, NEVER locking on my location. These occasions have been outside with clear sky. When I use GPSStatus, it shows 9 sats but 0 lock. I just don't understand how it can see 9 sats and not lock at all. I have a >10 year old POS handheld GPS that with no network, no maps, no anything locks every time within one minute. Samsung must have actually had to try to f--- this up.
Yes I have applied the cold start "fix" and it has made no difference, sometimes the GPS works and most of the time (especially when I NEED it) it does not.
Using the cold start method posted by aero1, my GPS.... sometimes works. Sitting in my car on a clear day with full signal, the GPS can take up to 5 minutes to get a lock. If I'm moving, It will sometimes lock onto me but still say "searching for GPS" so it won't give me driving directions... even though it can see where I am.
In cases when it does work, it lags a LOT. Sometimes it won't update my position for a minute... which is useless if I have a turn coming up that I don't know about. It is always jumping to where I am every few seconds. Google nav on the EVO was perfectly smooth. It stuck with me around turns and never lagged. Always perfectly accurate. It is the only thing I miss from the EVO.
I've completely given up on the GPS and use my Garmin (/wrists) whenever I need something reliable

Same results I'm having now. Using the workaround (cold start) it's hit or miss whether I get a lock or not regardless of how many sats my phone sees.
I put it to "cold boot" and am still getting shaky results. I used it to find my way back to my apartment but it kept putting me on the road NEXT TO the highway and jumping back and forth. Did this again when I was returning from work during lunch just to see if it happened again. Yep, gonna have to lug around my Garmin from now on.
Just sad.
Try this, weird but is working for me.
I installed an app from the market called GPS test to test my GPS signal strength.
Whenever I launch GPS test and then run google navigation it locks on within 10 seconds. If I don't launch GPS test after a cold boot then it takes forever to lock on.
So far this has been working for me for a couple of days. Might be a fluke though.

I've got three epics which allow me to do extensive controlled testing.
before applying the cold start fix my results were as follows on all three when in perfect sat condensations:
a) about 75% of the time no problem with locks
b) about 20% of the time I was getting many sats seen and none locked (expired ephemeris);
b) 5% or less I was getting few sats seen where they should be seen (bad almanac)
I applied cold start method to one Epic and for several days never experienced a failure to lock. I applied cold start to second Epic and now both Epics with cold start applied have gone over two weeks without a single failure to lock. I am now testing some other methods of flushing out cache
Top me this points to main problem being cache which for me ahs disappeared with cold start -- although there are other GPS problems on epic)
Other issues -- not addressed by cold start fix -- are inherent low SNR, SNR thresholds, samsung hacking the difference between fine and coarse results (30 meter hardcoded), these can all cause problems with GPS.
That said there is absolutely a repair of the main cache problem with cold start, I now see my 3g light up every single time I invoke GPS, with non net based applications, reflecting an objective and factual assistance data download --and without cold start I often would see no data usage on invoking GPS meaning failure to pull assistance data.

GPS after the update

I think I've updated my phone with something called Kies mini... I am trying to check my location with the gps but it aint even close to where I live!!!
Everyone talks about how satellites has their gps locked on to but I have no idea how to see that... with gps test.
HELP PLEASE! It has been always showing the same location doesnt matter which city I'm on! (before the update too)...
I think once I have tested this gps fix that was around, but then I went back to normal settings (i guess)... cause it didnt work
Now it it says that I have ECLAIR.UVJI6
I am new to all this
Search the market for an app called "GPS Test". It will show you all of the information you're looking for.
Well, I'm still having GPS difficulties with the newest update (Running Bionix 1.9).
ECLAIR.UVJI6 is the newest update, so don't worry about that.

I have GPS Test and GPS Status... The first one doest even move at all when I start the application and the second one on the bottom show it seems that is loading something forever. Where do I see the sats? Have no idea. From the second one I will guess that it could be that part that says "fix/sats" and right now is saying 0/2.
My goodness... The damn gps would so useful to stop loosing myself on the German streets
Nothing that I can do to fix it? Is there any news about if this is the last official fix for the gps?
My GPS was working great when I first odin JI6, now all of the sudden it just stop working, I try to odin it back to JI6 again and it still doesnt work so well.
I'm testing the GPS out right now. I've had the phone since wednesday, tried google maps and it's never been able to get my location. I just installed JI6 today and ran GPS test for the first time. I got 0 satellites for a couple of runs until my 3rd try where it eventually got up to 10.
Even though I get locks on GPS test, google maps/navi still can't pick up my location so it's useless =\
In my specific case, I found that the JI6 GPS update did not perform much better than the original version. Yes it was better, but certainly not as good as the JI2 update. So, I've applied the JI2 update and things seem to work much better.
Also, I've found that turning off wifi when making the initial GPS lock really helps reduce the amount of time needed to initially lock.
Good luck!
^ second that. Try to turn off wifi.

FYI - Ive had good luck changing to MS Based:
From link-
""In MS-Based mode, the network provides the satellite information to the device, based on a rough estimate of where the device is located, and the device acquires the GPS signals from the satellites and calculates its location. After the initial fix, the device operates like an autonomous GPS receiver, until the satellite information must be refreshed, at which time the device goes back to the network to update the satellite information. MS-Based mode is appropriate for applications that require the device location to be updated rapidly, such as a navigation application. Can the GPS work in autonomous mode? No, the GPS receiver requires the assistance of the network elements to acquire its initial location fix.""
i flashed bionix 1.9 and had more problems with gps than when i was running 1.5. atleast before it was sort of accurate... and found a couple sats after 2-3 minutes. but iwth 1.9... nothing and not even the correct side of the street (showed me east while i was way west). then i found someone who had a gps fix based on j12 and it was in zip so... i mounted that to me SD and reinstalled using clockwork recovery... now within seconds i get gps ... extremely accurate... AND... lock on to most of the satelites that are available. i love it!
Right, so here are my thoughts and experiences while using the new JI6 update:
1) Way more accurate than the previous couple of builds that I have tried. When the GPS does lock, it usually locks onto 10/12 birds and finds my location within 5-6 meters. Not bad! Definitely not as good as when I had GPS working via one of Eugene's Franken-Twiz ROMs (between 2-3 meters), but definitely good enough for daily navigation.
2) The fix for damn sure didn't fix any of the satellite aquisition problems that our phones have been experiencing. Typically for me it will aquire satellites right off the bat about 50% of the time. Other times I'm left waiting 20+ minutes for it to get a lock.
3) Solution I have found to get a quick fix. Type in *#3214789650# (for the new JI6 update) and delete the GPS Data cache. I think it's the last button on the list. After the cache is cleared, use the top button on the list to perform a location test. I've seen this take anywhere from 30 seconds up to 2 minutes... sometimes a bit longer if I am in an area with poor signal coverage. Once I have aquired a successful lock on multiple birds, I simply back out of the application and am good to go. If I leave GPS constantly on, I have found that my phone will maintain the lock almost indef. If I turn the feature off during the day to conserve battery life I have found that it will usually aquire a lock within 30 secs or so of me turning GPS back on IF I am still in the area where I turned the feature off. If I drive to an area an hour or so away from where I turned it off, I usually have to repeat the above process to get a quick fix.
I've tried every iteration of option combinations from the lbltest menu, and have mostly been greeted by similar results, with no one option particularly speeding up the process. Based off of this I am assuming the issue probably lies with the caching of stale data on our phones, and it's inability to purge this data on it's own.
The one thing I haven't tried yet is the JI2 fix mentioned above. I might give this a whirl and see how it works!
BTW, I'm an expat working in Europe, so this might also be the cause of my slow lock times... however every other GPS I own works magnificently over here.

That's the first "fix" for the gps? I tried once but it didnt work.
I have tried pretty much all the "fixes" I can think of and this is what I have found. No matter the source (root mods, Bionix, J12/J14/J15/J16-leaked and OTA), changing from 'standalone' to msbased helps tremendously. Also using the google server and port is much much better for faster locks and maintaining lock even if you are not in clear view of the sky (tree, buildings etc will affect you lock). I willl say the stock JFD with the msbased and google server and port was better than just about all the other ones I have tried with the stock standalone and spirint server.
IMO The OTA J16 is the fastest and most accurate (less than 10 feet everytime, less than 30sec fix everytime) that I have tried, but even that required me to use the google server and port, and also switch to msbased.

finds sats but won't lock on...
I'm still having GPS problems post-update. I've never installed any custom ROMs or any custom GPS fixes other than some tweaking in the LbsTestMode menus, which I have since reverted to the default.
In the LbsTest or the GPS Test app I get the same results: the phone always finds 10-12 satellites just fine (levels in the 20s) but it never locks onto my location. GPS Test will say "In View: 10" for 20 minutes but "In Use" always stays at 0.
Anybody have any ideas here? I was really hopeful that I'd finally have a functioning GPS after this update.

the thing is... mine worked in the states with the stock JFD without any problem. flawless.
it stopped working when i got overseas. and hasn't worked well since. It really seems like it ONLY works well in the states. I mean I can get it to work if I clear the data all the time, reset the phone all the time, but it's not supposed to work like that. It should just find me when i open maps like any sound person would expect from the device. can anyone contend? is anyone having flawless GPS functionality outside the US?

I've rebooted at least 5 or 6 times, as well as clearing the GPS cache ("Delete GPS Data" in LbsTestMode) numerous times as well. Still never gets a location lock despite seeing 10-11 satellites.

[Q] GPS lock issues?

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.

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.

[Q] Does anyone else have this problem with their GPS?

Ok so my problem is whenever I leave my phone on for an extended amount of time the gps just will not lock at all but after I reboot the phone it locks within a couple of seconds. This has been happening with each radio Di01, dj05, and Dl09. I was just wondering if anyone else had this problem and whether or not it is a hardware problem?
Nope. With DI01 I had issue where it took forever to lock, if at all. With DL09 I have no issue at all. Connects quickly and just works.
Sent from my SCH-I500 using XDA App
yeah. I thought I was the only one noticing that.
If I go into the gps setup (Dial: *#1472365#) and then go to command and start the gps, if the phone has been running for a long time, it will just sit there and say Number of Satellites: 0
But if I reboot, it starts finding satellites immediately and gets a fix super quickly.
Di01 was a nightmare with GPS locks...took upwards of 10 min or so. With dj09, I lock within 5 seconds max.

I may be seeing the same thing as you Jaybap. Can you elaborate what a "long time" is since boot that you're seeing? 12hrs? 2 days?
I had horrendous issues w/ GPS on OEM DI01 prior to playing around with Adryn's local xtra.bin solution. I'm now on OEM DL09 and for a day or so after the install GPS would lock w/in 10-15 seconds outside. I leave GPS and VZ Assist on all the time. Accuracy is dead-on for me. I'm using GPS Test and GPS Status apps for testing.
I am now noticing that after some amount of time (at least more than 24-36hrs after installing DL09, no boots since install) that my GPS tests took longer to lock (>1 minute). The GPS icon in the notify bar wouldn't animate while searching for satellites and at one point GPS Status seemed to hang/freeze (no FC). So after i saw this thread I booted the phone. Now the GPS icon animation is back when initially searching for satellites and i get a lock in 10-15sec. So ya might be onto something...
BTW - I'm guessing the GPS icon animates when searching for satellites; becomes a static icon once a lock is achieved.
How do I dl and install DL09?
Having GPS capability was one of the reasons I upgraded from a non-smartphone to a smartphone. Just my luck that the smartphone I choose has serious GPS issues.
How might I go about dling and installing this fix for the GPS?
Thanks.
keena It's the same way with my phone the gps icon stops animating and this occurs after i leave my phone on for a few hours and it takes minutes to lock when it used to take seconds.
I have the same issues. I can get a lock in seconds after I reboot, but if my phone has been on for more than 10 min getting a lock can take as long as 45 min or more, if at all.

Did you guys get your phones in September because I have a feeling they launched some of these with faulty hardware and that's why these updates aren't helping us.

Yeah, I nabbed mine on October 1st, so basically September.
But I'm still wondering if it's software related. Like maybe one thing (app? system?) in the background is trying to access the gps and won't let go of it for other apps to use.
Also, possibly unrelated: are you guys using Task Killers at all?
I also have the same issue as the OP. The only time I ever reboot my phone is right before I use Runkeeper... otherwise the Gps never locks.
I'm on dj05 using jt's clean rom & voodoo.

I bought my phone the 2nd week of December. I don't run any task killer or battery minder apps...basically just a rooted OEM DL09.
I noticed that if you turn on the GPS and leave it on all the time. It will always lock on fast whenever you turn on Google Navi/Maps. If you turn on the GPS, turn it off for a while, and later, turn on Navi, it will sometimes take forever to lock on.

DL30 and GPS

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.
