[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.

JI6 GPS still has major issues

Got excited after updating to JI6 this afternoon and the GPS locked on with 10 seconds, however tonight I went on a drive and the GPS wouldn't lock on after minutes. Finally gave up and rebooted which resolved the problem.
I'm also seeing some issues with the GPS being off by 100's of feet which is causing maps to reroute. Seems like mainly when stopped at a signal light.
Hopefully rebooting solved the first issue, but I not happy that there is still problems with GPS after waiting 2 months for a fix
Also the LAG seems worse. LAG needs to be the next top priority

That's a drag man, sorry to hear that. Maybe consider installing a custom ROM? I'm running Bionix 1.4, no lagfix because I'm getting zero lag. Rooting and flashing was very quick and my phone is now very responsive.
GPS is still hit or miss, but it's mostly hit and overall is working much better.
To be honest flashing this ROM has improved my phone ten fold.
Maybe give it a try. Just a thought, and sorry again to hear about your issues.

fix: flash (clockwork) "Vibrant-JI2-GPS.zip"
ji6 gps BLOWSSSSS

enter *#3214789650# and switch to MSmode, This solved the accuracy problem for me on JI6.
I don't know why samsung insists on seting Standalone mode for the GPS, Swiching to MSmode was the first thing we did to fix the GPS months ago.

Very strange. My phone is significantly faster, even better than before with OCLF. No stuttering at all.

Bionix 1.7 is the answer to your woes

Did you **** with any of the GPS settings prior to updating?
My GPS is working great, tracking, navigation and all. Lag? What lag?
Also, why did you think this topic deserved another thread? We already have one on this topic.. thanks.

Is anyone seeing their GPS just start wondering off? I'll be setting perfectly still and the GPS will start jumping in one direction by 100+ yards each time and it'll keep going, like yesterday I ended up over 200 miles away from where I actually was. Oh and instead of being on the street it has me in parking lots and fields. Not seeing the fix on my end.

It's working like a charm for me after JI6 !!!

GPS is fine for me and even better after enabling agps
For some reason agps is disabled by default.

Can you guys tell me your exact settings on the LbsTestMode? Not just the usual ms-mode/ supl.google.com/ 7276.. I need to know all the settings you have cos I messed with mine and want it back to stock

No problem here
I must be lucky, I am using Frankin Twiz final and a simple fix and i have 5-7 sats locks and 10-15 m accuracy. From all the reading...... depending on how you customized your phone, it seems to me that you have to customize the gps fix as well, as I see no absolute fix by anyone that works for all.

GPS
I got the update. The GPS worked for awhile but now it doesn't lock in. What's the best way to solve the problem?

Yes I have the same issue. I also noticed that when at a stoplight the gps will drift which causes maps to recaculate routes.

MS MODE helps only in decreasing the TTF/TTFF. it won't help with the accuracy issue both the OP and myself are having.

I don't see the USB icon after pluggning the cable. Anyone seeing this issue?
Preface: I was rooted with lagfix using OCLF. Prior to the OTA, I unrooted & uninstalled lagfix. My phone got locked up in Vibrant/Samsung screen during the OTA installtion like many others.
I used Odin to return the phone to stock, then download & flashed the JI6 file using Odin. GPS, compass, Task Manager, HD Camcorder, Youtube HD, Media Hub, etc are working fine ... however, no USB icon.

Has anyone else still not received this update?

People put your phone into fight mode and see how accurate GPS is after

Mine works perfectly, I am digging this update specially the new task manager. I can't wait for froyo.

[Q] GPS reset utility?

Does anyone know of a utility to reset the internal GPS completely?
I use location-based tools all the time, and this annoying GPS failure in EC05 is a real PITA.
I know some folks have had some luck doing a "cold start" using the GPS Status utility, but this has not worked for me.
Symptoms are that the GPS works fine for a while, then loses lock. Going into GPS status reveals no satellites visible at all, and the GPS icon on the notification bar is gone..
Using Menu/Tools/Manage A-GPS state I have tried both reseting the state (cold start) and downloading assistance data. Turning the GPS off and on again also does nothing. OTOH, if I simply reboot the phone, the GPS comes back right away.
Many have reported this issue was fixed in EB13, but came back in EC05. I'm running SRF 1.1 right now, but I also had this problem in the stock EC05 that I received OTA.
Having the GPS just work properly all the time would be ideal. But short of that, being able to restart it from scratch without having to reboot the phone would be an acceptable workaround. Even a command-line utility would be better than nothing.
-Sean

It's aggravating... I have the issue and I too am waiting for some kind of fix/workaround.

I use my GPS at my evening job pretty extensively. I suffered from this issue on DI18 ROMs daily, but I haven't experienced it yet since the dk17 froyo beta.

Exact same problems here. I am on Bonsai 4 but have also had the same problem with all the other EC05 roms I've flashed and the stock EC05. It was fantastic while it was working in EB13.

To those still having this issue, what method did you use to get to EC05?

It came back in ec05 because people didn't use the fixes we used in going from di18 > dk28 > eb13. Search these threads and do what we did and you won't have the problem either.

I was on whatever the stock Eclair release was out of the box -- bought the phone literally the day after Sprint suspended the EB13 OTA rollout.
I got EC05 pushed to me OTA a month later. GPS had the same issue on Eclair and EC05.
To get from the OTA EC05 to SRF I had to Odin back to EB13, but I only had EB13 on the phone for a few minutes -- did not test the GPS behavior.

I've tried a few things.. but at present, I went back to stock Eclair through Odin, then took the OTA to EC05.
Basically, I installed clean, so it's a mystery to me why others don't have this. Actually I think quite a few do, but haven't realized it yet... because the first time you get a fix after boot, it works magnificently well... 3-10 seconds. Great.
It's the down time after that, the hours that pass after that first fix that seems to change things. Without doing anything specific, just using the browser and other things.. the ability to AGAIN get a fix is hindered. Sometimes the GPS doesn't get one at all.
I'll let all the smart guys work on this one. I'm just a competent end user with no real knowledge of how the GPS works.

Just wanted to chime in..
I was waiting for someone to bring up this issue. Symptoms identical to OP's. Stock eclair worked perfectly, and this problem appeared in eb13, after a manual update. Ec05 did not change a thing and Gps status cold start did not help either.
This sucks since I use gps all the time.

As I noted above, I'm not a real gifted technician.. but I'm guessing this issue has something to do with the internal compass. I noticed that my two co-workers who both bought the Epic based on their favorable impressions of my phone, had issues with screen rotation after going from stock Eclair to EC05. Neither are advanced users. Neither rooted or otherwise messed with their phones. I too have tinkered with the compass.. the upside-down calibration and the terminal command pertaining to Yamaha.
I can effect the quality and time of the fix by waving the phone in a figure eight pattern in an attempt to calibrate.. so I'm thinking it's all related.

Running SFR 1.1.0 and I haven't experienced this yet. Took a three hour walk yesterday and CardioTrainer locked me the entire time even through the trails.
How long does it usually take for GPS to lose lock?
If it matters, I only enable GPS, not network-based location.

On DI18 based ROM's, the GPS data cache would not flush itself properly and you would lose GPS functionality usually within hours after it seemed to be working fine. My evening job I work as a delivery driver, and I would have to reboot my phone a couple times a night because of this bug. But as I stated earlier in this thread, I have not experienced this bug since dk17. I did experience some issues in DK28 where the GPS signal would drop out for a few seconds here and there, but since EB13, it's been perfect. No issues. My other Epic is stock EC05, so I will run some tests with that one tonight to see if I can get it to foul up.

So is anyone running Bonsai 4 experiencing this problem at all?
My understanding is that Bonsai uses an EB13-based kernel with only select EC05 elements, so perhaps it is not prone to this issue. If that's the case, that may be enough to make me switch to Bonsai from SRF.
It would also appear that the problem is not universal across all EC05 (and EC05-based ROM) users, as there have been several reports in this and other threads from people with no GPS problems at all. This makes me wonder, among other things, whether or not some specific app or module is either causing (or clearing?) the problem. Since lots of folks on stock OTA have the issue, that would likely be an OEM app.
This problem is a real PITA for me as I use the GPS all the time. Really, really want to find a solution.

If you just want to reset your GPS cache data, there is an onboard utility invoked by a dialer code. Open your phone dialer and punch in
##GPSCLRX#
That opens a dialog that requires you to key in the MSL code for your phone. Normally the Sprint support desk has to give this to you. (If they do, write it down for future use.) There are other methods to find the MSL, including this one.

Thanks, I have the MSL. I've also now placed a shortcut on the home screen directly to this utility, which actually bypasses the MSL. From Launcher Pro, long press on a blank area then select Shortcuts/Activities/com.android.hiddenmenu/GPSCLRX.
We'll see if using this GPSCLRX utility brings the GPS back to life next time it locks up.
While I am on the hiddenmenu subject, does anyone know which module is the GPSsetup utility? Supposedly this ships with the phone, and was previously (pre-Froyo) invoked with the dialer code *#1472365# but, according to threads on some other Galaxy-S forums, Samsung changed the code due to customer abuse. The alleged replacement code does not work for me, and I've tried all the obvious modules in hiddenmenu with no success.
In the interim, I've flashed LBSTestMode, which seems to work fine for reading and testing the GPS chipset, but is purportedly for a different chipset and so it is not clear if it can actually change settings (see androidforums.com/samsung-epic-4g/308885-gps-aquistion-ec05.html).

I could not find anything. The only Activity I saw with GPS in the name was the aforementioned GPSCLRX. However I should note that I am on SRF 1.1.0, and it is possible that K0nane removed this module from the ROM. Does anyone know if it is in the stock EC05 build? Also, what's the .apk named, so I can try to find it and load it?

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.

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

The Stock Roms works fine!!!

+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.

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.

GPS never works after Froyo

hi all.
Ever since I went from Froyo to Gingerbread-based ROMs (and since then to ICS) my GPS has never worked.
AngryGPS doesn't find a single sattelite after 15 minutes, it just like the GPS is dead.
All ROMs I try claim to have a good working GPS, however none actually works.
The GPS lock icon, which should be blinking, is there but not blinking.
Since most people claim to have a working GPS with ICS, could it be a problem with the phone itself?
(I always try the GPS after a reboot)
Thanks for your help.

Been having the same issue, i have tried tens of solutions and flashed tens of fixes, i even opened it to try to fix it and it still doesnt work like its suppose to. Google maps never get my accurate location, its usuallly about a mile off, mapquest however is able to give me turn by turn navigation albeit its often late in its guidance. Very frustrating.

Ics has had good gps for me since day one with ics passion....
Gb had great gps after jagf on eugene's kernel

Well, I do use ICS passion right now and I did use eugene's kernel at some point in the past (maybe with MIUI, don't exactly remember).
Anyway none of them had working GPS.
My phone was manufactured at July 2010. Could it be some old revision with GPS problems? Although I did apply the hardware fix back when I was using 2.2, which did help back then.

This is why I'm sadly back onto 2.2. GPS still sucks but better than on GB.
I did everything possible to get GPS to work on GB. I've done the hardware fix, I've flashed everything possible, and the only time it worked was after each reboot, and only then temporarily.

Agree 100%
GPS in ICS is flaky. It usually works right after reboot then it's a gamble. A few times it would work for me for a day, sometimes second run of GPS Test doesn't bring GPS icon up at all.
To make things worse, external GPS support is equally bad. I have a feeling it uses the same driver/daemon.
Obviously there's either not-so-compatible driver in kernel or the API is broken.

Try a app from the market called GPS Aids. It does help for me.

Unfortunately the "donate" version does nothing but ask for donations.
I would kick in something if it actually worked, but not on speculation.
GPS at least sort of worked with stock (whatever was on the phone when I got it used) but never at all with any CM build, including with various fixes applied. It at least sort of worked with Onecosmic's ICSSGS, at least once, maybe with some fix or other applied.

A quick update : Turns out, I need two conditions for the GPS to work:
1. The phone needs to be after a reboot, so it didn't go to deep sleep
2. Data connection (WiFi / 3G) should be enabled before you try to get a lock. Even when you use a satellite-only location! I think it downloads the satellite data from the internet. When you get a lock, the data connection can be disabled.
This is the only way I could get my GPS to work in ICS. Even in ROMs that promise the deep sleep problem was fixed.

Cyanogen never let me down, I was usually using some kernel that a worked with the ffc mod, but I literally never had a problem. Also try any miui with angry GPS

H ave any of you tried this? You just flash it from CWM. Worked wonders for me.

I did the this (kept stock kernel though) and flashed the files from this post...

The trick that worked for me was to get a GPS lock as soon as the phone boots up but before the screen shuts off (see Post #26 by dark79 in the above link). Usually takes about 30secs to look but works great even after deep sleep.

same here! doing this CM9+SZ work like a charm

CM7+yagf patch

My stock roms (Eclair & Froyo) never locked satellites properly until i started using CM7 and other patches. Worked OK for me but still it wasnt a very good solution.
