Hello:
I try use the GPS of Sprint Hero in Argentina (there are no operators that use CDMA)
and I can not find the satellite signals, what I can do?
Thanks in advance
Gps will not work without a network location first. You may be able to connect to a wifi and it work, maybe.

Are you using a custom ROM, or just stock 2.1?
Probably nothing you can do. The gps hardware is not powerful enough to work without a network location.

my thoughts are...
GPS works.. but without data it has no reference.
Maps must be downloaded via some internet connection. Maybe a wifi can help u.
or
you can download a stand alone GPS map app. CoPilot is a good one, but cost $30.
Yeah, but the gps can't even find a lock without a recent network signal to tell it where to start looking. It's not a full on gps antenna.

I have been traveling around the world recently with my EVO and using the GPS to do so. It's GPS chip is no better than the Hero's I believe.
Things to keep in mind, without aGPS help, it can take these things up to 30 minutes to find your correct location. Usually it takes 4 strong signals to pinpoint it. Download GPS Status from the market and it will show you all of the satellites it is picking up as well as the strengths and you will know when you have a lock. It will also allow you to keep the phone awake and the gps active until it gets a fix. This is probably your main problem. If the phone is not actively using the gps, it turns off the chip and never gets a chance to get a fix.
You need to run GPS status preferably when you are connected to a wifi signal and outside with a clear shot of the sky. It can take anywhere from 10 seconds to 30 minutes depending on if you are on a wifi connection, how far away you are from the last known lock stored in the chip (GPS Status will display this for you) and also how far from the equator you are, etc. If you are very far south in argentina it can be a LOT more difficult GPS to work... I noticed my GPS had waaay more trouble up in sweden than it did down in central europe.
Also, Download mapdroyd and get the maps for the area you are in. It works pretty well for a free locally stored map app. GPS Status also allows you to add pins/labels to gps coordinates and then do a radar type guidance back to them. Between these two tools and now knowing how to connect your phone, you should never get lost again, providing your battery does not die. Luckily I brought 4 extra batteries with me!
I cannot get the GPS to work correctly on any ROM that I flash. It either never finds the GPS and says searching for signal or finds it and cuts out really quick and gets stuck on searching for signal.
Ever thought its a hardware problem and not software?

Which ROMs are you flashing? The only one I've had trouble with GPS has been CyanogenMod, but it's a known issue there that the GPS doesn't work right.

Download GPS status from the market. Hit menu then select tools. Open manage agps state. Click clear data. Then download agps data. See if you get a lock then.

If that doesn't work, then try the CM7 GPS fix.
First make sure you are on a Sense ROM.
Get your MSL using the MSL reader app from the market.
Open your dialer and dial ##GPSCLRX#
When it asks for a password, enter your MSL and then your phone will reboot.

Hi to all, today i installed the 3.1 Stock ROM rooted wtih CWM and now i have the 4.010.05 COM GEN 1.
All perfect, i use it for 1 hour, but only the GPS have some problems to fix location.
With Honeycomb 3.0.1 I had the same problem but I thought that version 3.1 would solve it.
The GPS in this Tablet is a real hardware problem or software problem????
I must contact ACER to change my tablet with a new Iconia Tab A500???
Where is the problem with GPS????
Help me please.

A few seconds of actually scrolling down the forum page would have found you this...
I applied this update last night and had the same gps issue.
FYI, Although root is there, busybox is not....
My gps fix was to install faster fix (busybox required) from the market, loaded and locked in under 10 seconds.
Everything works great so far.....
Ok i copied the HD2 file "Gps.conf" in "Europe.zip" and seem that work indoor after a Reboot in recovery and Delete Cache and Delete Dalvik Cache.
This evening I test in car with Sygic and i tell if work.
My Iconia A500 has rooted and have Busybox and CMW.
I must use Faster Fix or not????
Thanks.
P.S.
The GPS problems is a software issue not an corrupt hardware module, it's right?

Since fasterfix simply replaces your existing gps.conf, you can always roll back to your existing if you have a copy. I would give it a try, cant hurt.
Ok this evening i try Iconia A500 in my car witg Sygic Gps Navigation.
The fix work but the signal isnt constant and sometimes it lost position and fix after few seconds, i dont know why!!!!!!
Now at my home outdoor the fix is slow after 3 hours without gps activity, Google Maps at start show me a wrong position, it give me the position of my parents house, why???
It's normal?
My Nexus one is more quickly and stable of this Gps and i think that this Tablet isnt a good solution for car navigation.
Any suggestions to solve my Gps problems???
Thanks

Yes, Sygic is my GPS app of choice as well, and this works with the newer releases.
About the gps i can confirm that while i was running virtous rom asus based 1.08 my gps was blazing fast I mean 10 found 10 fixed on gps essentials.. now with stock rom i still get a fix within 30 seconds but i only see 5 or 6 sats and lock on 2 or 3 so ..i would assume software is the problem or some app interferes with gps ....
I decided to use the solution of daveid and work perfectly in car.
One only thing, i must set 100% of screen brightness to see it during the day with sun or there is a lot of reflections....any solutions???

Make sure you select a country/region and set it which should be reflected in the 'current status' dialog.... Its not harmful but good for me may not be for your area of the world?????

The GPS for the LG GT540 is only supported for UK and US. As I live in New Zealand, it doesn't work for me unless I use the mod.
If you do live in those regions, see if it is receiving enough signal for it to make an assumption of the location. Wi-fi or cellular data makes the location more accurate.

It works for me, I live in Indonesia. I have compare the coordinate result between GT540 gps and field gps which was Garmin GPSMap and the result is quite good. In the format of Degree-Minute-Seconds, they're only slight different in 'seconds unit'.

After a long time (1 day) with the mobile switched on the GPS doesn't work, with any app, google maps, gps status or runtastic, I wait for the GPS fix status but the GPS system doesn't detect any satellite. Only few times works properly.
When it doesn't work I need to make a long batch to make it work, switch GPS off, run "fasterboot", run "GPS fix", switch GPS on, reboot and try it again... after this process some times works, and some times not... so I need to repeat the process until it works and it's a desperate situation.

Do you have data assisted location on? Go to --> Settings --> Location and security and then check if 'Use wireless networks' is only on. GPS will work with that on but will be less accurate that the use of an actual GPS connection. Also try it with both 'Use wireless networks' and 'Use GPS satellites' (if not already) and then try it with only 'Use GPS satellites' (to see if it actually determines location from satellites.
My GPS module seems to be also [email protected]#d up :/

I know what are you talking about... but the problem is when i'm running with runtastic software or walking with navigation the accuracy is horrible! I need that the GPS works properly, is one thing really necessary for my hobbies and job.
It doesn't work from the SwiftDroid with CM7. I read in other forums that the problem comes with CM7, but the fixes only works well with another brands of mobile phones. I'm thinking about to change to the [AOSP][v4.1] Android 2.3.5 or downgrade the Mur4ik version...

I use it sometimes of the road or while walking. I use it about once a week, but the frequency can fluctuate. I use MapDroyd. It's free on the Android Market and you can use it offline with a downloadable map.
I haven't had any real problems with the GPS and 2.3.5 although it seems to get a bit jittery occasionally (sometimes jumping up to 3 miles away from the current location) and every now and the GPS seems to shut down and restart.
I use Sygic GPS Navigation but it also happens with Google Maps as well.
Do you have or had 'Use wireless network' on. It happens to mine too. It seems like the location of which it used a data connection on is first used and then the actual location by a GPS.

Hi,When I use my phone for finding my location without using data connectivity - without relying on A-GPS so my phone finds my location after a lot of time or sometimes google maps can't find my location.
How can I solve this?
Thanks.
After day or so it won't get fix at all. Samsung just did something wrong I'm afraid. Looks like the GPS in SG2 NEEDS data to work. I found the hard way on my trip to Japan. I know no solution.
So I cant change my gps settings?

GPS in the S2 is weird. Some days it locks in seconds other times it takes forever. I never use A-GPS.
Today I couldn't get it to lock but last night it was instant. So I restored a CWM backup from last night, rebooted and it locked instantly.
I played around with MIUI for a couple of days and found lock time much better than stock or custom rom.
Also, changing server with fasterfix makes no difference when its having problems locking.
I just don't get it.

How do you 'never use AGPS' ? Btw. my problem is not time of the lock. But the fact, that without network, I don't get fix AT ALL. With network AGPS reset helps (many apps can do that). But without network GPS works only for some time (AGPS data still valid). After that you just won't get fix. It even looks like wifi connection won't help, it has to be mobile network.
It's because of crappy gps reciever or it can be improved by another rom?
Thanks
Sent from my GT-I9100 using XDA App
It seems the problem is that GPS is in mode, where it simply relies on AGPS. In older ROMs there was app called LBSTestMode where you could change the mode to stand alone, or just AGPS based. This application is not in newer ROMs, so it cannot be switched. It clearly is just a software thing. Except it looks that there is no solution which does not involve flashing roms and/or rooting.

Yeah I never use it. I don't tick 'use wireless networks' at all. To me that's fake GPS.
Since my last post, GPS has been perfect. Am able to lock up to 11 satellites sitting on the couch. On average it takes about 10 seconds to lock. Tested it at least 20 times today.
But who knows what will happen tomorrow!!!
Man, if you can only get a lock using wireless networks then I think your GPS might be stuffed.

That does not mean you don't use AGPS. AGPS is method, where data about GPS satellites are not downloaded from those satellites via GPS receiver, but rather from server via. mobile network. So I'm afraid you do use AGPS, unless you disable mobile networking (and wait about day for current data to become obsolete).
One thing I've noticed is that when I run Z-DeviceTest and bring up the GPS status display, it shows that none of the satellites have almanac data, and very rarely have ephemeris data. If that's accurate, that would suggest that if you've turned off AGPS and mobile networking, you could have some trouble.

Ok. So does that would mean it's impossible to get a GPS lock without data enabled? Or just harder to?
Maybe I shouldn't have mentioned AGPS, but instead wireless networks which show your position even though GPS is not locked.

It seems it may vary with ROM, and it is possible to switch it, at least older ROMs contain service menu module (LbsTestMode) to switch it. But my SG2 seems to be unable to get a fix without network. It simply does not even try do download Almanac or Ephemerides data from the satellites.
Also for AGPS, mobile network must be used, not WiFi. As I understand it, those AGPS server names are virtual, and network provider redirects them based on location .. which is not possible via WiFi.
I wonder WHY there is such option at all. Do mobile network providers want us to be unable to get a fix without them ?

Hey Dr, I think you have diagnosed my problem
Every so often I turn off data and use only wifi. One day my GPS locks in seconds then the next it takes forever.
So I have now tested it a couple of times over the last couple of days, when I can't get a lock I turn off wifi and turn on data. All of a sudden GPS locks again. Interesting!!
Hopefully that is it. Will test again the next time it won't lock.

Ha ! Breakthrough. I could get a fix without network ! But ..
I used newer version of 'GPS Status' app. It shows state of unconnected satellites with gray/blue/yellow based on how much data it has - none/almanac/ephemerides. So you can see if there is some progress or not.
So I disabled network (both wifi and mobile), disabled location from mobile network, left just GPS on .. run GPS status and used 'Reset AGPS'.
The connection has few 'phases':
1) you get signals from satellites .. you see it in power meter .. all are gray .. and their dots on the 'sky' view are all in the N. Sure, GPS does not know where the satellites are, and does not know where you are .. so it can't know where on the 'sky' they should show.
2) Some signals/dots turn blue. That means you have almanac data. Rough position of all satellites, which is transmitted by all satellites. That already means your GPS receiver was used to download some data from the satellites. Based on this, GPS can tell very roughly where you are, and will paint dots on the skyview.
3) Some signals/dots turn yellow. That means you successfully downloaded ephemerides data from that satellite, and it can be used in fix. Have enough of them, and you are done.
4) Some signals/dots turn green - you have fix. The error will get better over time as more satellites are used.
I took me over 5 minutes .. but thanks to this tool I could see I'm indeed receiving some data and there is some progress. Also it only worked outside, under open skies. I tried that in a car, in a bus, in a train .. after 10 minutes I did not get over phase 1. With AGPS I get fix in all such situations in few seconds.
It just looks like the data decoding module for almanac/ephemerides is not the same as for the time (which is used in fix itself). While time channel is quite sensitive and fine, data channel seems to have troubles with even slightest disturbances.
Still I'm happy I made it work in the end !
Btw. the fact that AGPS does not work over WiFi still holds.

Hi,When I use my phone for finding my location without using data connectivity - without relying on A-GPS so my phone finds my location after a lot of time or sometimes google maps can't find my location.
How can I solve this?
Thanks.

I rarely have the data connection on (just to save battery) and WiFi is only on where I know I have a known connection - thus it is off when outside.
I put on the GPS then immediately run Sygic satnav program. I will have a fix normally within 30 seconds and a worst case of about a minute (that I can remember).
I have just tried switching off and on my phone, putting on the GPS (from the Pull down menu) and run Sygic. From switching on the GPS, I had a lock in about a minute.

Could you try that with AGPS manually reset ? I recommend 'GPS Status' tool to do it, it's in 'tools' menu.
GPS lock time seems much improved in KJ4 firmware for me (i'm on orange 2.3.5)
all three DOP values in GPS Status now show figures (instead of infinity for two of them), and i'm getting reported accuracies of around 5 metres, instead of 14 - 20 metres on the older firmware.
