G1 GPS - G1 Q&A, Help & Troubleshooting

Hi, i had problems with my GPS, i had enabled the two option avaliable in the location settings. However i am able to find my location using the cell tower, but my gps sign just keeps on flashing and it was not able to lock to satellites. May i know if it is hardware issues or software?
I am able to lock to satellites before, however now it takes forever. Thank You.

Are you trying outside? It's difficult to get a signal inside.
"GPS Status" free from the market shows you some good data, like how many birds it can see.
BTW "flashing", the icon itself is appearing and disappearing or the icon is animating? Also what ROM are you on and in which application(s) are you trying.

This may not help that much but I damaged my long coax to the gps chip while I changed my housing. Since then it acts the same as you described, so you could be experiencing a hardware issue. The parts for the gps can be found online for about $40 if you determine its a hardware issue.

Hi, i am on KB7SQI's Rogers Mod 2.3, hmm i did tried it outdoor before and it refuses to lock on to the satellite. The icon of the gps will come on and off, it does not stay fixed, i have also tried on Google Maps App. It cannot detemine my location. Locking onto the satellite should take a few seconds, however mine took forever.
I am hoping it is not a hardware issue, importing parts would be very very expensive for me. I believe if it is a hardware issue,the icon will not even appear. Is there anyway i could test out whether my gps chip is working? Thank You.

Tilt GPS sometimes does not receive satellites

Using IGO (legal).
This happens with the new standard AT&T ROM, and with the previous one as well.
IGO starts and quickly obtains satellites, then every now and then, without any obvious reason, I get a verbal warning that no satellites are found, and the GPS icon turns red.
After a few seconds, or even a couple of minutes, GPS signal is restored.
The Tilt is positioned near the windshield, and the problem does not occur in "urban canyons".
I don't have any other GPS app with maps that I can use to check this.
I'd appreciate any ideas.
Thank you.
You could try a free app like Microsoft Live Search or Google Maps to check against IGO. I haven't really noticed mine dropping signal unless I do go into a real canyon or something like that. One thing - when the phone goes into Standby, the GPS chip turns off for battery conservation. Is it possible that your phone is going into standby when you lose signal?
mine does the same after update to the new att rom, and honestly, i dont have an answer for you.
Live search cannot ever find any satalites, which is why I have resorted to using Google Maps. It works fine for me. So try using google maps. its works much faster and more reliable in finding sats, imo.
try a different radio. it has been reported that it works for some.
replies
snooginsguy: No, it always happens when navigating.
grandpareza: not sur ethere are googlemaps for my country (at least not with any reasonable resolution). Will check later.
P1Tater: Replacing the radio requires HardSPL, which I haven't sone yet. As I said, I'm still with the original ROM. I live abroad, so there's no issue with warranty. It's just that I'm concerned I might brick my device.
i heard that you have to update with quick gps everytime before you use your actuall gps... that would improve the sat tracking a lot better
It's on auto update
So that's not the issue.

Anyone else having GPS problems?

My GPS worked fine all day, but when the phone was sitting on my desk running Google Maps (I get a pretty good GPS reception through a Velux window), I noticed my location rapidly heading off south of France. At that point the phone dropped the signal, and I haven't been able to get a lock since.
GPS Status is only showing the one satellite lock, Google Maps can't get a position fix either. Tried restarting the phone, and have run out of ideas. Just about to try the TomTom to see if it can get a lock here...
From what you're describing, with no software able to get a lock, could be a hardware failure. Try logging a support call with HTC.
Hi Rob,
Just an update to this - I checked the NOTAMs and it turns out the military was conducting GPS jamming trials. The GPS received worked fine the next morning.
Kind regards,
Dave.

[Q] Problem with GPS - never locks

Anyone else having problems using the GPS on this device? I've tried several different GPS apps and none are working. The problem is that is finds 2-3 satellites, but never gets locked.

1 - Download "GPS Status & Toolbox" (EclipSim) from market
2 - Enable Location from Settings in order to use A-GPS data.
3 - Enable Use GPS from Settings
4 - Run "GPS Status & Toolbox" and then go to "GPS Status & Toolbox" menu where you can clear A-GPS and then download newest A-GPS data.
If you can't get a fix after this, you might have faulty SW or HW
You could also try "GpsFix" from the Market.
Sent from my LG-P990 using XDA App
Thanks I'll give them a try.
I've now also tried to pair this phone with my holux m 1000 (bluetooth), but can't even get that to work. I managed to pair them, but it won't connect to the phone.
Is it just mine or is this phone so useless?
i am having the same problem too
Hi,
I'm using Sygic Mobile Maps 10 8.2 and Google Maps (unlocked with navigation). Both work fine with GPS and fix is within 5 sec.
Yet to try my stereo Bluetooth headset, will try in a sec ...
Edit: Headset at work, will try tomorrow...
This phone is very good for gps navigation.
Google Maps Navigation, Sygic Mobile Maps 10, Copilot Live, Navigon and Igomyway are working fine. They give me a lock within a few seconds.
A few tips:
Under Settings - Location and Security:
- enable using wireless networks
- enable GPS-satellites
If you're using WiFi the fix will be faster then without.
Oh yes, and one more thing: don't forget to insert your SIM-card.
For me to get gps fix, i need to stand outdoor without any roof on top of me, this is so bad if I'm indoor and beside a window, i can see a few satellites but it just wont lock on.
Is this software problem? I don't wish that it is my hardware problem

lol its a gps you use it outdoor not indoor. is not designed to work indoor. so i can't see you problem?
Fixed it!
I called LG, and got the recipe for fixing the gps.
Do a "hard factory reset"
Turn off phone
hold HOME and VOLUME DOWN and POWER until you see the android. Then wait.
Done. It now sees 10 satelittes indoors, and uses them all, as opposed to maybe seeing one, and never using any.

LG made a booboo.
There is no gps.conf in /system/etc, so there is no assistance. I pushed the file from a Nexus One (attached) into place and that sorts it.

I tried to use gps.conf and supl method but no luck, the issue weren't there. My gps was a jerk, last week i spent 30minutes to fix the satellite while driving in town. Even standing under the sky, the fastest I am able to fix is 200seconds, not to mention there are many times they wont even fix.
But my problem was stopped once i changed from stock to other rom. so I guess there is something else wrong in the stock rom, as the other roms are able to perform well even without gps.conf. (around 20-30 sec fix time).
So I guess only when your gps is able to lock satellite, gps.conf will help to speed it up. At least that's what happen to me

[Q] Streak 7 wifi, stock ROM- gps unable to lock

My Streak 7 wifi, stock ROM- gps unable to lock. Other than that, device is great. Wifi connected. In settings, Wireless networks and GPS satellites in use. GPS Status & Toolbox app downloaded aGPS data but not helping, GpsFix app not helping to lock also. Any other suggestions? thanks in advance.

Not to be too mundane, but have you tried a simple reboot, or going outside where you'd be more likely to get a GPS fix? My T-Mobile S7 has had trouble getting a GPS fix several times, but other times it locks right in.
How long have you left in in clear line of sight of the sky to get a lock? I use mine as my primary in-car multimedia center/GPS and at first, to save battery, would turn it completely off when not in use. I found that when I'd get in my car to go home from work it could take up to 10 minutes to get a lock. Then I started just letting it sleep, have had no battery issues and GPS lock is nearly instant.
Long story short: Give it a good while to lock after a full shut down.And maybe you have, I just thought I'd share my experience.
Jeff
I have absolutely the same issue. After turning it off completely, the GPS does not lock for ages in any sky conditions, etc. Moreover, I put another two Android devices (Galaxy S and Optimus One) also after complete shut off juyst nearby and they are getting locked almest immediately. No doubts, there is a bug in the S7 GPS. But what is it ? Is it a hardware problem ? Can it be fixed ? Keeping it in a sleep mode for a long time is not a good solution for me, though it works indeed.
Does anybody know how to fix it ? At the moment I am using an external GPS. It works perfect, but it is also not that elegant solution.
Same thing here too. I downloaded "GPS test", and found that it will lock on pretty quick, then fire up GPS, and all is well.

GPS on android devices need the assistance of the cell tower or ISP location to get a quick lock. When you first boot up the ds7 and turn on GPS, make sure you are connected to wifi in order to get a quick lock. If you search this forum you will see a thread that give a fix for this, but I think its too much of a hassle. Just be on wifi for your first lock will do the trick. This is not bug on the ds7, its android.

Really? More misinformation on this subject? No, Android devices do not need aGPS, in this case you're confusing aGPS (ie: download of ephemeris data) with Network location, which are quite different.
And it really doesn't matter if it's the first or the Nth time, if the DS7 is always offline for some reason, it would likely make that first fix take 5+ minutes but subsequent fixes (for 7 or so days) would be fine. However, as soon as he goes online, it's going to download the ephemeris data.
My guess is that his GPS conf is set to the wrong part of the world, so the ephemeris data is basically invalid. FasterFix in the market can help correct this mistake if you're rooted, or you can replace it manually.

I beg to differ with you. When I was on stock froyo, I had the same GPS lock problem on one of my trip. So I pulled into a McDonald and connected to their free wifi and got an instant lock. This morning I tested it again. I have been running honeycomb sine Oct 5th and have never turn on the GPS. I connected to my wifi, turned on GPS, and opened Google map and got an instant lock. I didn't have to wait 5+ min..

This is a little FAQ I wrote up on how to fix this problem. Just a matter of replacing the file that runs the GPS, based off the area you live in.

Good list, although not sure why you're specifying dozens of NTP servers vs the pool server, but I assume t-mobile lets anyone connect to its server to download the ephemeris data? Otherwise, probably better to use supl.google.com
Here's mine, for North America, with other regions commented out for NTP. http://dl.dropbox.com/u/334233/gps.conf
It'd be interesting to know if all of the other dozen or so configuration options are actually used, I've heard they aren't, just part of a spec.
I bought my DS7 in the US and I live in Israel. The above explanations perfectly fit my case. Unfortunately, the given link does not include my region (Israel or Middle East, etc). Can somebody help me ? My DS7 runs a stock HC 3.2. The device is unrooted, but I will root it just for solving the GPS problem. BTW, why my Galaxy S bought in Europe does not have such problem ? Is this gps.conf specific in tablets only or in the US devices ?
Another thoughts. Now it seems to me extremely unreasonable to run specific GPS files in different regions. GPS, by definition is supposed to be used in different regions. Should I replace the GPS file in my every trip? Sounds more than unreasonable. I used a Windows CE based PDA with GPS all around the globe without that issue. It does took me a while to fix satellites in a new region for the first time. But then it was getting fixed fast even after complete shut off.
I can't beleive Android is that imperfect. If this option would be included in the menu (e.g. in Regional settings), I would like it. But performing such complicated actions in each trip ???

Stop your trolling, ephemeris data, ie: what's set up in gps.conf, is to speed up cold starts. it does nothing else, it's not Android specific, in fact all it's doing is downloaded a set of the data that your GPS would otherwise have to slowly acquire from the satellites, which takes 2-10 minutes, depending on conditions and how many sats are seen.
All GPS units do this, but GPS units that have a network available will potentially download ephemeris data to speed up satellite acquisition. Otherwise they just download it. Only time you'll really notice it going slow is if it's been more than 4-5 days (I believe 7 is the official data expiration, but the older it is, the less accurate it is) or you've changed areas since you last turned on the GPS.
Keep in mind that phone-based GPS's suck. They're inaccurate, they're not sensitive, their antennas are not optimal. This is true for nearly all PDA's or Phones, Tablets, etc.. Some may be better than others. They're optimized for space, price, and somewhat for battery life. Not accuracy, precision, or cold starts (beyond A-GPS data downloads, which is an OS function that makes the data available to the GPS)
This means my unit is faulty (apparently it is a common problem for DS7). Otherwise I would have similar cold starts for all three devices I have tested (DS7, Galaxy S and Optimus One). On the other hand, in the light of your explanataion, my tests are, probably, wrong. DS7 is WiFi only, while another two are GSM (no data plans though). In other forums, I read that changing gps.conf file in WiFi only devices dramatically improves cold starts. Apparently they all have been connected to WiFi while starting. I have prepared the appropriate file for my region, but don't know how to root my DS7 with stock HC 3.2. The thread I found here is not sufficiently detail for noobs like me. So, in the mean time I will continue using the external GPS. It is indeed much better than the internal one besides the cold start problem (though much less convinient). If you know a link to the step-by-step instructions for rooting DS7 running stock HC 3.2, I will greatly appreciate it.

Always possible there's a problem with the GPS, maybe the antenna is defective or connected badly. Hope you figure it out.
I have two bluetooth GPS, one Holux 236 I've had about 6 years, another Columbus V900 I was going to replace the Holux with, as it's newer, should have better sensitivity, and has built-in track logging. Except that its accuracy is off, it's precise.... precisely wrong. It's always about 9 meters off. And my primarily use for it is Geocaching, and my Holux 236 is always dead on.. So my new BT GPS is basically used as a track logger. Ah well All that said, I primarily use the BT GPS with my phone while geocaching or hiking or such, but I have used it on the tablet a few times, but most often I just use the built-in GPS on my DS7 because I don't need high precision with it the way I use it.

Thank you, khaytsus.
All this fix does is speed up the initial contact to the GPS satellites for your region. You don't have to use this, you can wait till the GPS in the DS7 makes contact if you want.

The most strange is that the GPS is fine after getting fixed . At least, no difference with Galaxy S, i.e. roughly the same number of satellites, SNR, accuracy. So, the only problem is unreasonably long cold start. I am not sure how it could be caused by a defective antenna. Anyway, in the mean time I decided to use an external GPS. I have three units, two BT and one mouse, which I used to use with my nettop in the pre-tablet era. Yesterday I connected my Hollux 236 to 12 V using a concealed cable and switch. So, now the procedure is reasonably simple: switch on 236, a few clicks on BluetoothGPS and, when the connection is established, I am clicking iGO8. It works like a charm, besides several additional actions I have to perform. When I will sicceed to root my DS7, I will try to play with the gps.conf file anyway.
P.S. I got an idea to connect my mouse GPS using the DS7 docking unit. I have a simple one with two microUSB I/O. Not sure it will work, but, if yes, it can simplify everything dramatically. I will try it on the weekend and let you know about the results.
Thanks.
OK, after two weeks of testing I still don't have a reasonable solution:
1. The USB mouse GPS connected the cradle does not work at all.
2. My greatest disapointment is with the external GPS. It works perfect... when it works. I am using the Bluetooth GPS application to get connected. After several successful connections, without any visible reason, the GPS is not getting connected to DS7, although the application shows many satellites with large SNR (>30-35). However accuracy = 0 and no GPS signal message in iGO8. This happens only from time to time and as I have already mentioned without any visible reason.
Will try another applications and GPS devices.

[Q] GPS dropping in sleep/standby

Hi,
I've done a fair amount of searching on here and google regarding the gps issues with this phone. Tightening the screws definitely helps with the lock time, but I am still having issues with the device dropping gps lock when the display is off.
I have an S3 Mini running stock Android 4.1.2 and mainly use Viewranger for mapping and the GPS status app. Both apps work fine while the display is on, but when it goes off, gps lock is lost after an indeterminate amount of time. Setting GPS Status to 'Use gps when screen is dimmed' makes no difference.
I use both of the above GPS apps on a HTC Wildfire and a Galaxy Tab 8.9 and neither drop GPS lock when the screen is dimmed, so it is definitely an issue the S3 mini.
Here's hoping for a fix on this otherwise great device!
TIA
fourth ooplotel
Maybe I should rephrase the question
Is anyone here *not* having a problem with GPS lock when the display sleeps?
Ta
I hav the same problem which means I'm unabble to use running apps.... Have you found a solution?
No fix yet unfortunately, and it's looking increasingly like there never will be one.
I've been taking a GT8.9 in my backpack for GPS on walking trips. I'll also keep my old wildfire in case I need a pocket-sized GPS device that actually works!

Hi, i've just purchased the S3 mini phone and I have the same problem. Previously I had a Wildfire S one and I've never had any problem, even taking into account I use GPS to track my trip when I sail on the sea. I'll try to summarize some clues I've found:
- Samnsung Galaxy S3 mini with Android 4.1.2
- I usually use "Marine" app, from Navionics join "GPS Status"
- The problem only appears with "track" option, after stand-by, but after an indeterminated amount of time.
- Once we check the GPS is not working, I can see on GPS Status the satellites but no one providing position (i.e. value of 0/12 on pos/sat field). Finally I need to restart the app, GPS Status and the GPS to get the connection again.
- In other forums I've ridden about not to switch off the screen to avoid Android turn off the GPS because of energy safe mode. With tracking function should not be necessary do it.
I hope anyone can give us some light.

Thanks for the suggestion but I tried both of those apps and neither prevented the gps dropping lock when the screen was off. In fact, my gps/map application would stop tracking my location when the screen was on and either of the above were running in the background, so they actually made the situation worse!

- Once we check the GPS is not working, I can see on GPS Status the satellites but no one providing position (i.e. value of 0/12 on pos/sat field). Finally I need to restart the app, GPS Status and the GPS to get the connection again.

Have the same problem. Often 0/12 with "strong" signal. But no FIX. And it happens short time after 11/12 (or so).
This happens with various ROMs (all based on Stock)
