G1 GPS

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.

I have just upgraded from v2.1 with a wipe, thus this is a wierd problem for me. Any Idea, besides hardware problem? Thanks

Did Froyo include SPP for Bluetooth GPS?

Android so far as far as I can determine does NOT support using a Bluetooth GPS for the location data but I'm hoping maybe Froyo does..
The GPS built into phones is fine for car nav and some low-resolution stuff, but to have any accuracy or hold a decent lock under heavy foliage or urban jungles a bluetooth GPS with a dedicated chipset is necessary.
I geocache a lot, and my Holux 236 has never failed me, it always has lead me right to where a geocache is, yet my Nexus One tonight the heading and distance stuck, stuttered, seemed to be 20+ feet off at times, and almost IMMEDIATELY went stupid after going under foliage.
I've seen a few programs that'll use Bluetooth GPS themselves, but they are one-off programs which use the GPS directly, not replace the internal GPS data with the Bluetooth GPS data which is what I really need.

Anyone with Froyo and a bluetooth GPS?

i would like to know to

The answer was no... Still an open issue, probably will remain an open issue.
http://code.google.com/p/android/issues/detail?id=9057
Looks like there's maybe two possibilities, one open-ended "I have solved this" with no real info, and another "Bluetooth GPS Mouse" app in market that is said to work. I'm going to try.

So far this seems to work! I've got an email out to the author, I'll post some more on it soon.
Pretty slick the way he's done it, I have a question out to how automatic the GPS connection/redirection is upon reconnection of the device (ie: do you need to reconnect it manually or is it automaic) and if it's not automatic right now, I'll stress that it needs to be.
It did immediately get coordinates when I connected it to my Holux 236, where the internal would take 10-15+ seconds and the coordinates would wander around for a while. This got coordinates and they stuck... I watched carefully and I saw the latitude go .605 to .606 then back to .605 a few times.. I didn't make sure they were accurate yet, I'll do that later, but by eyeball they were.
It doesn't seem to report sats fixed nor sat signal levels.. I'm concerned this might make some apps think there is no fix and wait forever for it. GeOrg and GPS Test seemed to not care, they reported the right location and it seemed to work.
I did not put it through any real life tests, just sat in my car in the parking lot at work and checked out my location.
I'm concerned if other important info like altitude, bearing, and speed are reported. I'll update when I get a response to the email of course.
One more thing I forgot to ask but I'll see in practice is if using this I can still use the electronic compass. Not that it's great, but it is convenient. Honestly though I'll still be happy without it.
There is a free trial that disconnects every 10m, or a 2 euro paid version. Very reasonable.

Author responded, he sounds right on top of the current limitations and is working on them. I suspect once he has worked on this a tad more, it'll work great. Give the trial version a try and see how it works!
I found that nearly all of my geocaching programs "just work", no fuss. I found that Google Earth gets an accurate fix but can't seem to find "My Location". Both seem to be because he's working on getting the satelite fix data into the program, if possible. Right now it reports 0.
Built-in compass still works fine!
He'll be working on automatic reconnection after he tweaks a few more things and sees what kind of efficiencies he can make and bugs he can drive out.

I was successfully using GPS Mouse with stock Eclair 2.1 & my GlobalSat Bluetooth GPS with my running program.
I have since flashed to Froyo JPO rom & now when I try & use the program I feel a vibration in the phone, the screen soon goes black & then does a mini re-boot & back to my home screen again??
I done some google searches but cannot seem to find an answer to thsi particualr issue

I'm using Bluetooth GPS Provider now, it works FLAWLESSLY, start and forget it while I'm using the GPS. Even if the GPS disconnects, phone is in standby extended periods, etc, always immediately reconnects and works.
As for your specific problem, dunno, but give it a try.

I have the same problem, anyone a solution ? Please ....

Try Bluetooth GPS Provider, it works awesome for me. Reconnects immediately, works great.
If you have a ROM-specific issue, you need to talk to the ROM cook.

[Q] Problem With GPS

Hi guys,
ok, my GPS has not worked on my Galaxy S for a long time now. I am always flashing new roms, kernals and it may be something to do with that.
Currently I am running the MUIU Beta rom, but it hasnt worked on previous roms like Darkys.
I decided to download GPS aids from the market ro run some tests.
It downloads the LTO test file, but is unable to copy it.
It says "The application cannot copy files from SDcard to a SYSTEM folder. Maybe it is a busybox problem"
Busybox 1.18.4 is installed to /sbin/
GPS aids has superuser permissions
Google maps hasnt been able to get a fix for a long time. GPS Test cannot find any satelites.
Not sure what I did to cause this problem, but can it be fixed?
Is this a hardware issue?

I know it sounds silly, but do you have your wireless turned on when you are trying to use your GPS? After flashing to 2.2 on my Galaxy S, I found that I couldn't get a GPS lock without having my wireless turned on!
Edit: My original thread is here: http://forum.xda-developers.com/showthread.php?t=986151

Thanks for the quick answer.
Yes the Wifi is switched on, but nothing. Not even one satelite.
The funny thing is that the GPS used to work great. A lot of people werent happy with it but I had no problems.
I got a lock within 10 seconds. I just dont know what I have done to stop it working! lol

Flashing roms you may now have a bad modem or wrong set up especially as you have a beta rom and darky rom .
I would flash stock with pit 512 and reparation checked in other words build a clean phone .

Have you tried the gps test app to see if it is at least seeing the gps satellites or possibly getting a lock?

Hi, yes Ive tried that app. It doesnt find any satelites at all. Nothing!

Unfortunately, I really can't think of anything else. Sadly I believe JJEgan's advice above maybe the only other option
This thread has another possible option http://forum.xda-developers.com/showthread.php?t=974702
You may also want to check out the GPS settings on the phone. I'd have to search the forums for the code that gives you access to them.
*#*#1472365#*#* for 2.1 Eclair.
*#*#3214789650#*#* for 2.2 Froyo.

Not sure, but give this a try... my i9000 can get a gps lock in about 5 seconds with no wifi.
Download Fasterfix from the marketplace.
Run it and choose the region that you are in.
In the Location settings, turn off "Use wireless networks" and turn on "Use GPS Satellites"
Go into the LbsTestMode
*#*#1472365#*#* for 2.1 Eclair.
*#*#3214789650#*#* for 2.2 Froyo.
Application settings - Operation mode - Standalone
Application settings - Accuracy - 100
SUPL/CP Settings - Auto Config
Re-boot your phone
Go back into the LbsTestMode
Get Position Test - Let it run for at least 3 minutes while your phone is outside (clear sky view).
Delete GPS Data.
Hopefully that will work for you as well. I was unable to get a GPS lock without wifi prior to this, and now my GPS locks perfectly on its own.

Galaxy S GPS Can't find satelites

I Deffinitly Tried everything, I tried the hardware fix, Change The Pool To Israel, France, Europe, everywhere, I tried the gps doctors , nothing works..
I just can't find any satelites, in the gps aid app when i press the GPS doctor it's telling me that the gps status is off.. is there anything that I didn't try and could work?
Please, I'm Desprit..
I Tried and the problem is at every rom
I'm Right now using ICS RC3.1 By onecosmic..

try gps status , to see if is an app error from navigator and other gps programs or RC3.1 probleme , and if are ICS probleme try first to flash devil led kernel
and a wipe cache

I though onecosmic's RC 3.X was only for the i9000 and not i9001.

Well I Tried and looked at the gps status, I didn't really get what am i sepoused to do there, I reset and cleared all gps data and downloaded it after wards..
the app didn't show any errors ..

Try to get GPS Aids from market. Had the same problem and that fixed my gps

Tried the gps aids too... Ain't working.. anything else?...
When I tried the gps doctor at gps aids, it showed me that the gps mode status is not working (the cube near it is red) and after trying the setup and the fix everything possibility it still ain't working... any idea?

Try to download the GPS test and install it, then go to settings and select clear agps, then update agps.
Oh and dont try the gps inside your house! Try it in the middle of the street! Gps signal is always reeeally weak or undetectable inside a house.

Unhappy to say, still didn't work!

Can you post the exact ROM and kernel version you are using?
Also try the following. Disable wifi, reboot phone, try GPS test.
I had GPS problems a while ago and the workaround was to boot the phone with wifi disabled. Something todo with init scripts messing up GPS/BT.
When in Google maps do you get the GPS icon in the status bar when trying to GPS fix?

try this http://www.youtube.com/watch?v=STlb...xt=C3c039cbUDOEgsToPDskJOGd0pTyqyB6SPWL6OcwDB

Better to just send it back to samsung for them to fix if it's under warranty. If not, just sell it and get another one. I really like my SGS but i've given up hope for gps. I've just accepted it doesn't work and be happy the phone's great in everything else (like sound). Was kind of gutted having paid so much for a phone with a non-working gps but to be honest i have little need for a gps so when i need one i just use a dedicated one.

Now I'm using RC4.2 ICS By Onecosmic, Gps Still aint working well, I do get the gps icon... but still, my location ain't really accurate and I cant navigate or anything..
I tried the video that have been posted, None improvment...
Is there any thing else?..

The GPS issue with the i9000 is a mystery to me. I've tried software and hardware fixes to no avail with GB based ROMs. However, when I switched to Slim's ICS ROM my device started to register satelites again with the GPS test app from the market. Despite this when I open the maps app it takes forever to get a fix, so long infact that I give up long before it ever does

Same issue AOKP Milestone 4 ICS. Nothing on GPS Status.

I use market app GPS aid.

[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.

I have the same problem and think I have the solution (I am still testing, but sofar so god).
Use Keep My GPS Alive (testing) or GPS Keeper Lite / Keep Alive (still to try). Look for them in google play.

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!

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)
