[FIX] Updated: GPS Tracking Issues (Optional FIX) For Stock Phones - Vibrant Android Development

Team,
boodies posted this in the General section and thought it should be here as well, due to its nature.

I tried this and all GPS and compass issues are now fixed. GPS locks on accurately in just a few seconds.
***This fix may not work if you live outside of USA.***
##You can play with the settings if you want to. If you FUBAR your GPS a simple factory reset will return your setting to default. You can do this without going into recovery buy going to Settings / Privacy / Factory data reset.##
Edit:
***************************************************************
Tested Procedure:
1 - Disable "Use Wireless Networks" - Settings / Location & Security
2 - Dial *#*#1472365#*#*
3 - Under "Application settings" Change "Operation Mode" to MS Based
4 - Under "SUPL/CP Settings" Change the SERVER & PORT to supl.google.com and port 7276 [ Do not use www. in front of supl]
5 - REBOOT
6 - Turn back on the "User Wireless Networks"

*****************************
Optional New Fix:
1 - Dial *#*#1472365#*#*
2 - Go outside to get an unimpeded GPS fix.
3 - Choose Delete GPS Data button.
4 - Choose Get Position Test button. Let it run for 3 min or until you have 10 to 12 Sat locks and back out.
Thanks goes to Onlyloki for this method.
You may want to do this in conjunction with the first procedure and then do the optional if the first procedure did not work for you. I did both and my GPS is locking even faster. Let me know what you think...
Just some more info I dug up:
Quote from http://www.vzwdevelopers.com/aims/public/menu/lbs/LBSFAQ.jsp
"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."
With the rapid updating we could see an increased drain on the battery. I have not confirmed that yet. If anyone can let us know.
Edit #2:
I was informed by a sales rep at T-Mobile that Samsung is aware of the issue and is going to fix the GPS and the compass issue in their first update.

does everyone have the gps problem or just some cause to me it doesnt seem like i have it just wondering

Mine were working ok, but compass was all over the place. After fix it was alot faster locking in and compass was fine. Noticed it using skymap, layer, etc...

fix worked great for me. All I need it to be semi close and this makes the lock within seconds. Before I couldnt even get a lock.. Awesome XDA

My gps takes awhile to lock. But before i try this.
What is the orig settings? Can someone post?
I dont want to do this and then if it doesnt work i cant revert

Don't you lose out on better accuracy by disabling wireless networks?

What are your settings set to?
Also check out a compass app and skymap are they throwing you all over?
I'm curious.

This is a shining example of what makes it great to be an Android phone owner, the outstanding community support that XDA has is second to none in my opinion, even to carrier/vendor support. My Vibrant should be arriving Tuesday or Wednesday (can't wait). I used to have Sapphire, then switched to the HD2 because I'm bound to T-Mobile and Windows Mobile was more horrible than I could have imagined. I can't wait to see CM6 with Froyo on the Vibrant...makes my mouth water thinking about it. Thanks again for the great work.

compass and skymap ARE acting strange... guess the nav was working because i happened to get a quick gps fix? i'll choose to believe that over the possibility i could have jinxed myself by saying i had no problems...
i have noticed that the battery drain is much higher (like abnormaly so) if you have the gps toggled on through tw and have something like beautiful widgets on...

would something like the QuickGPS app on HD2 solve some of these problems? anyone familiar with that app and what it does?

I did this *fix* and it killed my GPS.
so, I have reverted back to normal.

I noticed I'm getting a much better GPS lock in maps. The problem with skymap appears to be unrelated to GPS and appears to be something with the compass. On my G1, it tracked as I turned it with fairly precise accuracy. With the vibrant, it has a 5-6 second delay on tracking movement on the horizontal (up and down tracking in near perfect). However, the compass app seems to function just fine in that regard, oddly enough.

Same here. The compass was not affected by this fix, it is still acting like garbage.
The GPS does lock faster now, but before this it was working reasonably.

I will remove compass fix from my title. I saw an improvement but can not prove this fix will correct the compass issue.

Thought I'd chime in here.
With the default settings my GPS and compass seemed to be working fine, but I thought I'd check these new settings out. I have since reverted back to the original settings b/c the change actually made my GPS less accurate and my compass seemed to get a little funky.
GPS: Original settings is showing my exact location; down to the actual room in the house. New settings I wasn't even on the correct street!
Compass: Original settings in Skymap the compass is steady. Once it finds it self it sits there. New settings the map was rotating without me moving.
Figured this would be helpful to those out there who's GPS/compass seems to be working fine with the stock settings!

Just out of curiosity what are your original settings set to?

The same listed by the OP. I checked them before I made any changes.

Try these GPS settings

Disable (and do not enable even after we're done here) Use Wireless Networks under Settings ---> Location and Security.
Go into LbsTestMode (*#*#1472365#*#*)
Go to Application Settings
Enable MS-Based Mode
Increase Accuracy to 100
Leave the rest stock
Return to the main LbsTestMode menu
Go to SUPL/CP Settings
Select the Serve FQDN Type drop down menu
Hit AUTO Config
Exit to the dialer and reboot your Vibrant twice for good measure.
If the accuracy of your location degrades try using the stock www.spirent-lcs.com settings again.
Now from what I can tell, Google Maps works much better with these settings. The first lock takes 15-40 seconds depending on your view of the sky(indoors/out). You may get a "Location Unavailable" message from the first hit of My Location but it should come around shortly after.
The accuracy is good enough for in-car tracking. Haven't testing walking yet
I'll report back if I find that the GPS eventually ****s the bed and takes much longer for the subsequent fresh fixes.. which seems to be the trend for a new Vibrant. Also, moving your hand away from the GPS antenna will make things quicker. It's to the far right of the camera.
lemme give this thing a shot...hope this works

I must've deleted which MS - Mode but make sure it's MS-Based and not Assisted. Make sure you leave Wireless Networks off completely as well because this will prevent a GPS fix in GMaps for some reason.
Let me know if it works any better!
I gotta say so far this is the best fix yet I did everything but had to reboot a third time cause for some reason I wasn't connecting to data, but after that it was golden I did the satellite test and it got 14 satellites in about 5 seconds so it seems to me that this works the best. Thanks for the find, but what does skyhook do you have the option to turn it on or off what's the difference?
Thanks
Thank you sir for this fix..i just tested this and i got my gps lock with in 10 sec...Cheers!

seems to be some sort of location based software...might be worth a shot
Nice Fix - thanks, works well
will this method help at all with My Location being set to Pawcatuck, CT (when I'm in Houston, TX) while indoors? Problem occurs randomly.
WOW it works took less than 10 seconds to get a signal indoors.
Thanks.

I can't say for sure since I've never had this problem. Maybe someone else has and will try this otherwise, the only way for you to know would be to try it out. If AUTO-Config gives you these problems move back to spirent-lcs

I live in Houston, and I get that randomly when I'm at work. I have that problem with the old and new Vibrant. The new Vibrant, locks on my location when I step outdoors though with no problem at all. I'm just testing this FIX to see will it fix the indoor problem, but so far, it just showing me I cant find a location.
Edit: After 5min it found my location... Running the GPS Test and it actually locks on and off 1 Satellite..

Cool, doing the fix now.
For indoor the new method does not get me a GPS lock. For outdoors I didn't have problems using the previous fix.

Samsung has now officially acknowledge this problem and has promised a fix
See:

So I did this change and got 11 satellites in my office in the GPS Test option from those test mode settings BUT GMaps still says unavailable. Any advice?
Man I am so bummed...i really wanted this to work...i don't use the gps sll the time but I use it enough that I am almost regretting my purchase..i hope I can get a gps lock tonight so I can actually find my way...this is really frustrating

What is it with people in Houston all having this problem. I wonder if it is just the area we are all in (I work near the Medical Center.) I want to trade my phone in for a new one but if its going to have the same problem I am not sure it would be worth it. Are you having the problem still after you switched yours out? Is anyone else getting the error of "Not enough space in music database" when trying to listen to music and selecting the "Artist" category?
I'm in Houston and its always saying I'm in Houston and I tested the gps while in my truck and its great but indoors its not that great... but is need it more in my truck anyway so who cares lol
Anyone else having issues with the settings in the LbsTestMode menu not sticking? I was able to implement one of the posted fixes here before, but not this one as the settings will not stay. They change successfully on each screen, but as soon as I go back and then return to the screen, they are back to where they started. I can even confirm the settings did not change at the bottom of the main LbsTestMode menu with the status display. I've turned off the Wireless Networks setting under location before trying this many different times, reboots out the wazoo and at different stages(tried changing the setting, rebooting immediately without checking it again and no go). Also did a 'Delete GPS Data' with no help.
*edit* It appears I can change the SUPL server address and port just fine, but the operation mode change from MS Based to Standalone does not stay.

[Q] My GPS hasn't worked since updating to 2.2 - help! - RESOLVED

Hi,
I got a Samsung Galaxy S here in Australia, rooted it and upgraded from 2.1 to 2.2 I know that GPS worked just fine with 2.1, I was able to walk home and see my position updating very nicely on Google maps
Since updating to 2.2, GPS hasn't worked at all. When I turn it on, and start an application that uses GPS (Navigation, Maps, etc), the GPS icon sits there and flashes back and forth between those two types of icons and I don't get anything on the maps which shows me where I am. I haven't chased this up since upgrading, but it's starting to bug me now
After searching these forums for 'gps not working', I've pulled down the 'GPS test' application and I don't know for sure, but it appears to find one satellite:
PRN SNR Elev Azim Flags
2 11.0 74.0 150.0
But the GPS icon just sits there flashing back and forth.
I may have missed something since upgrading, do I need to do something to the phone to get my GPS working again?
Thanks!
OK, I seem to have fixed the problem I turned on "Use wireless networks" and voila! I now have successful GPS lock and position in my maps
I would have thought that you could use GPS without having "Use wireless networks" turned on!?

Wouldn't call it a successful GPS lock. Since you got it with the mobile networks. (in my case when I use it . the accuracy in my village is about 1000-1500m since the BTS is that much far from me )
So if you get into an area with weak mobile networks, wont help you much .
Wouldnt call this as resolved with "BAD GPS" cuz your GPS still sucks as before (and doesnt work , you just found a workaround that was there also before , 2.2.1 has even some other function for GPS that tries to fix it (or help?) )
But since you can use it now, its ok I guess . OH and there are kinda almost no real fixes for this. Most of SGS GPS suck . There is GPS aids, shutting down wifi, GPS status app, changing the something according to your country.
Ok!
I got the same problem as the user from the post.
GPS worked like a charm on my Galaxy S (NDrive or Google) running 2.1.
I updated it to Froyo 2.2.1 JS7 and since then it doesn`t work anymore.
I can't get a fix.
I did the GPS position test and It locks on 8 satelites. Why the F%CK it doesn`t work anymore?
I am almost going back to Eclair.
Any sugestions?
TY!
So you get a lock when doing the GPS test, but no luck in any other applications? I couldn't get a lock at all until I turned on my wireless as well as the GPS, then it worked for GPS test as well as applications...
I get a lock on 8 satelites on the Location Test with and without "Use Wireless connections".
BUT
I can't get a lock when I am using Google maps, with or without "Use Wireless connections".
I bought the AIDS GPS app on Market, but it did't work neither.
PROBLEM SOLVED!
I updated to Gingerbread (2.3.3) and my problem was solved. Hope it helps somebody!

[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.

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)

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.

[9001]GPS Lag

Hi, i have a nasty GPS lag, on some Days GPS works fine and on other Days i become a fix and then i lost the fix, all the time. Thats anoing!
GPS Fix is realy fast - 2-5 Seconds. I have tried Android 2.3.3 - 2.3.5!
Anyone else with this problem?

Me too, i think that the gps is very poor, at least for me. Yesterday the sport tracker gps doesn´t worked fine.
Do you know if are there any fix for that?
With Android 2.3.6 i have reboots when i using my gps...i think it's a hardware Problem...
Me too, gps taking fix and then lost and repeat again... and other times woring fine. I not have idea at this
Sent from my GT-I9001
So noone using SGS+ can tell me that their phone's GPS is working properly? On any ROM (including the stock ROMs, even the branded ones)? And that apps like FasterFix do not help?
i have used FasterFix to change NTP server to europe.pool and then used GPSAids with "Other" selection in Setup, then downloaded GPS aiding data.... TRY
...for me this helps a lot.i get fix to 1 minute, and that is very good with samsung
I'm using i9001XXKP4 and the GPS takes a long time to get a fix. I was walking to work today and after about 8 minutes trying to get a fix it didn't.
When i first upgraded to i9001XXKP4 (the phone came with some 2.3.3 version i cant rememer not, bought in the UK) I noticed that the compass wasnt working and the GPS coudln't get a fix but after a reboot (i didn't reboot since installing the new version) the compass started working and the GPS got a fix while outdoors holding skill in about 2 minutes.
still compared to my previous budget ZTE blade, which got a lock in seconds, this galaxy is waaaay slow.
i've used the instructions found on the web to enable something called GPS Plus.
aparently it was a feature of the i9000 but can also be found on the i9001.
(remember, i'm on i9001XXKP4)
basically:
dial:
*#*#3214789650#*#*
this will open an activity called AngryGPS
Go to Settings> General Settings and set:
Operation Mode: MSBASED
Start mode: Hotstart
GPS Plus: ON
Accuracy: 50
then to go back to
Settings > SUPL Settings
and set:
Servert FQDN type to: Auto.
Just in you need the original settings, here they are
Server
supl.google.com
7276
UMTS SLP
OFF
SUPL
VerSign
but the software saves the original settings and changes back to the google server if you choose custom again.
Reboot the phone and that it.
It got a lock in about 20 seconds with me walking with the device in hand and eventually locked on 10 sattellites. half of them were high quality signal.
worked inside the car in my hand no problem but the signal is a little stronger if i put it below the windshield.
anyway... hope it helps.

when I dial that number it opens the normal GPS settings. No extra settings for operation, start mode, etc...
are you on i9001XXKP4?
I'm usinng a rooted i9001XXKP4 maybe thats it.

hmm, I see what was wrong. The settings page came in front of Angry GPS so I had to quickly tap the back button twice.
(Same ROM as you, also rooted)
It works now! Thanks
Will try this..hehe

[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)
