[Q] Does JI6 OTA update fix the GPS and Compass?

Hey XDA community,
I have been reading a lot of positive things about JI6 and that the GPS is finally fixed. I am kind of a sceptic because I have been reading for a while that compass is seriously messed up on all Galaxy S phones and that it may actually be a hardware issue that can't be fixed with software. I have read that people are getting locks to satellites and that it locks quickly, but has anyone tested the compass to see if that has been addressed also?
If anyone has tested this on JI6 can you tell us how well the compass is working with the GPS and also how the accuracy seems after updating?

The compass was perfect in the JI5 release, so it's not a hardware problem. I'm running the leaked JI6 and the compass is ok, but not as good as it was in JI5. I'm going to flash the official JI6 tonight...hopefully it'll be good again.

Compass is prefect on official ji6. Gps is as good as from ji2 on which is not perfect but reliable...

GPS is working great. If it's bugging out disable Wireless Networks and make sure all of the settings under LbsTestMode are stock.. they do carry over if you update.
I can open up maps and expect a fix. Compass is working.. it has been changed for the better since JI2. It's not a "hardware" issue.

I can't open LBStestmode anymore with this new update, i think my settings are still screwed up from last time when i was messing with it.

The new code is *#3214789650#. The settings are exactly the same as JFD, Spirent, Standalone, etc.
You might want to delete GPS data, disable WiFi and wait for your first fix.

My GPS has always worked pretty good and on JI6 it seems even better but I haven't had a chance to do a lot of testing. My compass so far is finally working. It wasn't working too well at first but it started working great after calibrating it.

My settings are different now. My server shows:
h-slp.mnc260.mcc310.pub.3gpp
and I'm now MS-Based.

Are you sure you didn't change them prior? I flashed from a complete wipe and they are most definitely not like that.

GPS definitely works much better after the OTA update. However, i'm still curious as how it holds up to other smartphones. I created a thread for people who have another smartphone to compare JI6 GPS to other smartphone GPS performance.

my odin update went smoothly. the gps is perfect now, but the compass still has a few issues. seems like i have to calibrate it every time i use it. after that its ok, usable, but not perfect.

I just noticed that myself. It's like it doesn't want to save or keep the calibration setting.

I'm trying to upload a video showing how fast I get my lock over WiFi or the GSM network but Youtube keeps speeding it up. Coming soon..
I flashed the "OTA" JI6 recently to avoid any problems. The file sizes are exactly the same. The GPS performs the same.

Can someone post the stock settings?

Like I said above, they're the same as they always have been. Standalone, Accuracy @ 50, www.spirent-lcs.com 7575..

Compass and GPS perfect for me after the update (used ODIN, didn't feel like waiting).

That's the weird part. I did play around with settings; after the Captivate OTA I managed to get those guys to post their GPS settings and I applied them to my Vibrant. Here's the server they gave me:
- h-slp.mnc410.mcc310.pub.3gpp
I tried it and it didn't work so I thought (not quite sure) I had gone back to spirent.
But my auto config settings after JI6 is definitely
h-slp.mnc260.mcc310.pub.3gpp
Not quite the same, and I didn't input that string, so it came with the update.
Now, I tried inputting spirent-lcs and also did a toggling of Standalone vs. MS-Based... no significant difference in GPS performance. I did think that I was able to get lock quicker on Standalone when Wifi was on, but I'll have to test that out more.
Regardless, I can use spirent or the mnc260 server and performance is the same. The GPS fix is definitely not in any user settings.

Thanks for all of the replies everyone.
I finally got tired of waiting for the OTA and I flashed JI6.
In my experiences the GPS does perform better than stock but it definitely doesn't seem 100% fixed. If I am stationary and I use the GPS Test app I have about 11 satellites in view and I would consistently be locked to 7-10 of the 11. This is an improvement from my stock GPS especially for the amount of time it takes for the GPS to lock
I took the GPS for a drive though and the accuracy seemed bad. The GPS seemed to lag about 30 feet behind my actual location. Halfway through my drive (it was only a 10 min drive) my GPS completely lost me when I made a turn and then navigator froze until I locked the screen and then unlocked it.
Before upgrading to JI6 I reset GPS data, rolled back to full stock except root, and did a factory reset under the privacy settings.
Is anyone else having accuracy issues and problems with the GPS losing its lock while driving around or is it just my phone?
I will test it more and report back.

JI6 Problems
The GPS locks good sometimes but then it is terrible most of the time. Signal drops still occur & I was going down a street (Google Maps) & the video had me visually going the opposite way.

[TempFIX] For those GPS still suffer for locked

Just wanna share with u guys regard my finding on how temporary fix the GPS issue. Just follow the step below:
1) Install the GPS test app from market.
2)Open the GPS test app and let it search for the GPS signal and locked it. (this step take few minutes.)
3) after get locked on the GPS test app and open the google maps. you now should be able to get GPS lock in few second and enjoy ur navigation.
my testing rom detail as below:
Sombionix nero beta3 rom
Baseband version: JL1
kernel version: 2.6.32.9
Hope this can help u guys and kindly share ur find out too with diff rom u have by the method I given.
Thanks.

Before anything, thank you very much for sharing with us.
But is this any different than actually waiting to get a lock on Maps? I mean if the GPS test takes "a few minutes" why not just wait for Maps to get a lock instead? I just want to clarify things.

Based on my find out, if just open the maps, it will nvr get locked. while using GPS test app, although still take few minutes but at least can locked the signal.

Running Axura 2.1 and my GPS never works. Attempted your method and no avail.

This method works for me, may be its just placebo effect, but still thanks a lot.

you could have got a lock with lbstestmode(*#*#3214789650#*#*) and then opened maps.

Funny thing is I was using nero 1,2,3 and the obsidian ROMs till now..but I just installed Master's latest AXURA 2.2.5.8. I flashed directly from nero 3 to axura 2.2.5.8 via rom manager without odining back to stock or anything..and magically my GPS locks now in 5-10 seconds.

My gps NEVER worked until I installed Axura 2.1 AND the JL1 baseband.
since then my gps works flawlessly.
it takes about 1-2 minutes to get a lock but then it works perfectly.
try flashing the baseband since AXURA 2.1 comes with JK6 if i'm not mistaken.

do you axura 2.2.1 source? what base is using? I do want to try also...

I don't mean to troll, but this isn't really a "fix," all it does is "prime" Google Maps/Nav so Google Maps/Nav won't give up if it can't find a lock in a set period of time.
There are 3 real "fixes" that exist:
1) Flashing to a newer modem (JL series, take your pick)
2) The hardware fix posted in General from plato which involves improving the contact on the GPS antenna
3) The software fix from the Captivate forums from Da_G that involves changing the jupiter.xml settings for a) removing post-processing and b) using "true" AGPS settings optimized for your network
There are "mini-fixes" that help improve GPS performance (changing SUPL server to supl.google.com:7276, disabling WiFi antenna to reduce EFI), but again these are not true fixes.
Aside from the 3 fixes above, the rest are really just beating a very dead horse.

I dont think its a placebo effect. My GPS was dead until I performed the hardware fix early last week. But even then GM didnt seem to want to lock until I got lock in GPS test first. Someone posted about it in the hardware fix thread. We may have found the hardware problem but apparently there is still a software problem . No matter... Ill take running GPS Test first over no GPS at all.

This method works. I posted about it in General about 2 weeks ago to see if anyone wants to test it but I didnt get any response.
Yes GPS test locks quickly with the JLX modems on the different roms. 8/9 birds within 20 meters in about 20 seconds..blah blah blah. But how many of you actually try to use it during navigation. It works for a while then goes nuts and thinks you are on a street 200 yards away. Sometimes it corrects itself, sometimes it doesnt. Either way it is not reliable.
If you run GPS test and get a good lock then switch over to Navigation. Set your destination. Look back to GPS test to make sure it is still lock then drive. You do not get the jumping around effect. Been doing this constantly for almost a month now without that jumping effect. The key is to make sure GPS test is locked on in the first place. It keeps Navigation from losing that lock and jumping around.

One thing, there are two GPS Tests. Both are nice apps, but for the best lock use the one developed by Mike Lockwood. Open it, start it, and when it locks simply go back home and select Google Maps.
The best true fix is the hardware one. Whatever you do with software is just improvements.

yup. been doing this method for quite a while now.

For me what works and give me a quick lock is going to the GpsRestore Application by Samsung let it restore settings. i don't wait for it to get a lock. I switch to Gpstest application and get a fix very fast most of the time. After that any application that use gps will lock fast.
Hope this helps!

Wow! I can't believe so many people are still spinning their wheels on GPS when a definitive thread which fixes it has been sticked for so long. Especially after someone posted a link to the thread with the fix in this thread.
Heck, the link to the GPS fix was even covered on TalkAndroid in the news section a while ago.

Running Stock EB13 or DK28 ROM with Root? GPS Works? PLEASE READ

It may not be EB13's fault but I'm having a heck of a time getting my GPS working. At this point nothing I've seen has been able to hlep so I'm posting a plea here for information.
I'm asking for people whose GPSs do work to send me the contents of some files related to Froyo's GPS settings. These won't be affected by custom kernels, recoveries, or roots, but WILL be affected by ROMs so I'm asking for stock only.
The two files I'm looking for are
1) /data/gps/secgps.conf and
2) /system/etc/gps.conf
.conf files are simple text files that can be opened in programs like notepad and gedit so please just post the text contents as a reply, no need to clog the system with attachments.
Feel free to ask me for help on getting these files, but I'm not looking for people to root solely for this purpose.
Thank You!
PS for those who wish to point out there is already a thread with configuration settings that are supposed to fix GPS, I have already tried these settings and am asking so I can see some more information.

Mine also has been accurate and connects quick with lock times of within 5 seconds and 10+ sats locked with 10+ seen, even with wireless networks unchecked (using GPS only).

Thank You!
Thank you very much.
For those looking here for answers, unfortunately this didn't provide any clues. I'm done for the night, but supposedly there's a ticket on my account with Samsung to get me straight to level 3 support if I get a chance to call them during business hours... I'll keep you posted.
To summarize what I've tried (in almost every logical combination):
*#GPSCLRX# and reboot
*#7780#
##786#
*#767*3855#
Probably some other 'reset' type dialer codes.
Re-Flash EB13 modem 3x (with full reboot)
Re-Flash EB13 3x
Re-Flash DK28 modem 3x (no reboot) then EB13 modem
Re-Flash DI18 3x then Update.zip
Re-Flash DI18 modem 3x (no reboot) then EB13 modem
Modifying secgps.conf to various combinations of recommend settings, most notably AGPS_MODE<-1, SESSION_TYPE<-1, OPERATION_MODE<-MSBASED, START_MODE<-HOT,SUPL_HOST<-supl.google.com,SUPL_PORT<-7276
Side note the last two are logically alternated in pairs
PS: I wasn't clear before, but it's not that I'm not getting a fix, I am seeing NO satellites while outside etc. etc.. I know the hardware in there is OK somehow because I got it to work ONCE under DI18 but only after playing with lbstestmode settings.

Not to be a party pooper, but have you considered an intermittent hardware fault? One in which you have a power management system that is faulty or unable to keep the GPS working properly? Case in point, I had a Palm Pre (I got the first one in West Nashville) that would maintain Bluetooth connectivity for a few minutes - even an entire phonecall. However, as soon as the phone went to sleep, Bluetooth would disconnect. No matter how many times I flashed or reset, it always did this - my replacement unit worked perfectly as far as Bluetooth went.
So, perhaps you may have an errant/intermittent power issue for your GPS chipset. Do you have TEP?

Ironic side-note, btw - I've had flawless, constant GPS locks every day with WiFi turned on since EB13. I kid you not, after I ran cat /data/gps/secgps.conf, it has stopped working consistently. Twice now. Of course, I know this is an impossibility - those files are locked and uneditable, and I didn't have root - but what are the odds?

I'd suggest flashing back to 2.1 stock with odin or heimdal(including modem), getting a lock with gmaps and reupdating to 2.2 after. This was the solution to the gps issues for most people with the leaked froyo builds who had issues.

TEP = Total Equipment Protection? No, but I shouldn't need it... this would fall under the Galaxy's warranty.
Hardware failure (intermittent or otherwise) is what I thought it was form the beginning (NO satellites shouldn't be caused by any software problems a re-flash couldn't fix), this stopped working when I got my phone back from Samsung for an RMA on the speakerphone... they could have (and probably did) copy my MEID to a refurb that wasn't fully refurbed. Problem is going to be convincing Samsung of that fact... Tier 2 (the 24 hour tier apparently starts at 2) tried to convince me it was an issue with my Sprint plan... only after much insisting and say the words "it comes form satellites, not sprint" a few times did they even offer to move me to tier 3... we'll see what happens with them tomorrow.

Good luck!

Status update
I called Samsung today and after arguing with the regular tech support for a few minutes they bumped me to "senior support" who agreed this would have to be a hardware problem and gave me another RMA... in addition to being without my android for another week it's just pathetic that it took a senior support staff member to acknowledge that GPS came from satellites and not Sprint... Should have gone with TEP.

I don't recall seeing this listed in what you tried, so here goes...
Have you tried doing an ##RTN# (##786#) reset on your phone (as per this thread: easiest way to fix gps using DK28) to see if that helps?

First GPS Problem on my Epic!! Are you having the same problem?

Hello,
I am running EF02, I odined it, and I just found a huge issue, GPS Stops working after like 30 minutes of use. It basically turns off if you have it on too long.
Heres a way to replicate it:
Open Telenav, Enter an address, let it guide you for 30 minutes, and before that, you phone should vibrate (force close vibrate) and the voice over will say "cannot get GPS Signal in this area".
Is anyone else having this issue?
Thanks

I will try that tomorrow on my way to work. What is a good test and signal quality for the GPS? I downloaded GPS Test lite from the market. I am running EF02. I went in my back yard and the test program tells me 7-9 satellites in view, using 2, accuracy 18ft. Does that sound like a healthy GPS signal? Is there a better testing program?

That's a good program, the gps location and tracking works fine,but it stops working after a certain amount of time, and can only be fixed by reboot. I've never had this problem on froyo or eclair, I just hope sprint realizes this issue and fixes it

I actually had this same issue on 2.2 while i would use google nav. I noticed it when i took a several hour road trip about every hour to half hour id have to disconnect my gps and reconnect it.

I have the same issue too. For me GPS stops working in about 10 minutes of use. Google Nav would just sit there with trying to reconnect to GPS and says GPS signal loss. Tried EF02 and EF10 modems.
Used GPS Status & Toolbox app from market to get it working again instead of restarting the phone, but GPS still stops working in about 10 minutes of use.
In the mean time I might just flash back to ACS 1.1.1 or the new one just released 1.2

Yep. Mine does the same.

I'm having a couple of these GPS issues as well, never had them before. I've always been able to get GPS functional on every eclair, froyo, and gingerbread release until now (ef02).
GPS Test app shows around 8-9 satellites in view, and only 1-2 in use. Previously, I would always have 8-9 visible and 8-9 in use. I think this is causing my second problem which is:
GPS accuracy is way down over previous releases. It used to be near-pinpoint accuracy, now it's much less accurate. Today driving in to work, the accuracy was so bad that when I was on the highway and if there were secondary roads close to the highway, maps would often place me on those secondary roads and start telling me how to get back to the highway. I've never had this problem before. I'm also getting the telltale large blue circle in maps depicting the poor accuracy.
I'm also having the problem where GPS signal will just totally drop after 10-15 minutes of navigation.
I've tried the usual tricks with resetting agps, etc., nothing has worked so far.
Edit: I'm on the EF02 modem, not sure that it matters though

Wow that really blows, if this the case, I'm going back to Froyo ... I rarely use the GPS but when I do, it's for long trips and I can't have it dying on me traveling to places I am unfamiliar with. Thanks for the bug report on this OP, it seems everyone is having the problem, regardless of baseband EF02 or EF10.

Glad to find out it is not just me having this issue.

Same problem here. Went back to Froyo EC05, no problems again.
I guess I'll be waiting for them to make progress. GPS is essential for me, I use it on a daily basis.

I had the same problem and eco3 modem works for me
I have been using it mon,tues.wed all day 700am till 800pm and it never disconnects on me.
So far so good

After trying everything on Anonymous to get gps to work I finally gave up. Odin'd ef02 stockplus and gps works flawlessly...used it for an hour drive today without any hickups..give this rom a try....very smooth and fast for Rfs

+1 on that my brother! I believe the problem lays in the Ext4 Roms and the other modified roms. The stock roms work perfectly. This is the first time I am endorsing the stock roms. I believe our developers are trying to do a lot without the source code.

Any solution for this issue yet? I rely far to much on my GPS which is why I can't use EF builds is simply cause of this one issue.

Odin the EF02 stock roms. They have a lot of work to do on the Ext4 Roms to get them to work properly.

Just had to vent (at myself, for not having the time to delve into non-stock ROMs the right way but still installing the leaked EF02): my GPS is completely wonky with EF02, and I've tried the EC05, EF02 and EF10 modems. None make a difference.
Now I'm debating whether to go back to EC05 and wait for the official link, or just live with it. Kicking myself...

It happens on EF02 stock as well. I had the same issues on a road trip I took after switching to EF02, would have to reboot constantly in my case to get it working right. Then tried flashing the EE03 modem, still had the problem. But as goku said, flashing to the EC05 Froyo modem seems to have resolved it.

GSP working under JB rom

I'm not sure if this is going to be considered advertising, but I finally got my gps working and I'd like to share my experience with the rest of the people. so if anyone is curious, I'm using JB v20 with thor2002ro touch recovery 1.7.3 and kernel 3.7-rc8. I used FasterFix to set desired server for downloading gps data and than GPSfix deluxe to get a lock. it took me about five minutes to get a lock on my location with 5 satelites under a cloudy winter sky. after that it now takes only a couple of seconds for a fix. so that's it. hope this helps
