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] Is anyone having problems with Google Sky after the JI6 Update?

After updating to the latest Samsung firmware, JI6, I noticed several things. On the positive side, the GPS and the Compass both perform better than the original JFD firmware.
On the negative side, I noticed that Google Sky is showing up approximately 180 degrees out of phase. (Best to think of this orientation problem as the need to look through the back case of your phone rather than look at the screen). I noticed this problem because, last *night*, Google Sky indicated that the sun was above my head, when it should have been on the other side of the planet.
I elected to apply the JI2 GPS patch to see if that might help with this problem (because I didn't have this problem with JFD). As expected my GPS and Compass continued to perform better than with JFD. And, the good news is that this fixed the Google Sky orientation problem!
Just curious to know if anyone else is having this problem with JI6.

Did you have any problems applying the ji2 fix over the official ji6 ota update?

@jstein222, I didn't have any problems applying the JI2 patch on top of JI6. That said, I backed up everything first just in case it didn't take.

cool, i'm going to give that a try my gps actually worked with the ji2 fix and gets absolutely no locks with the new ji6.

I noticed that even with the JI2 patch applied to the JI6 build that I sometimes also have trouble getting locks. I think there is some RFI going on between the different radio components in the Vibrant.
I've found that if I turn off WiFi before using the GPS, I get locks much, much faster.

I checked the Google Night Sky app since you asked and I'm having the same issue. It's not a deal breaker for me, but I'm going to play with the stock JI6 for a few days more before I install the JI2 files. Maybe Google will release an update in that time.....maybe.

Calibrate the compass using the figure 8 motion. I had the same issue after the update until I calibrated the compass. Now works fine.

Had to do this for regular Maps as well, not just for Sky Maps.

@inverseflux & avogl, Thanks for the calibration idea. I tried to calibrate using a Compass tool from the Marketplace. It seems as if my compass is actually working fine in both JI6 and JI2... That's to say that it points N/S/E/W regardless of how I'm tilting the phone. That is a far improvement over JFD. And when it points N in JI6 it also points N with the JI2 GPS mod.
In JI6, it seems as if things are 180 degrees out of phase vis-a-vis the front-to-back orientation of the phone. In JI2, this problem didn't occur.
It is possible that I haven't properly calibrated, so is there a specific tool you can recommend?

GPS Issues still...

When I made the switch to android one of the things I was most excited for was google maps and free turn-by-turn. I have tried everything to make this happen on my Fascinate. I upgraded to 2.2 and even tried the GPS Aids app. So my question to you guys is will the GPS ever work properly on this device or is there any other tricks I can try?
Thanks!

Did you update the radio?
My gps work great. Even the voice is much better.

Uh. What issues are you even having? Although I do have some minor issues also. It connects perfect but every few minutes it drop GPS signal for about a minute and then picks it back upnot sure when this happened or how long or what version it started on as I barely ever use it.

I can never get a lock on my location, even after letting it sit for several minutes. It is always in the right area but off with a massive blue circle.

He's got at least VZW location services on due to the massive blue circle, which uses cellular triangulation. Wifi can get you a smaller circle, but doesn't work as well as GPS.
My phone has been totally unable to get a GPS lock for quite a while (since upgrading to EB01 based roms, but even on DI01 and DJ05 it was incredibly pathetic), even with updating the A-GPS data and having VZW & Google location services on.

I have tried all suggested issues. Do you think it is a hardware issue with my phone and I should trade it in or am I still missing something?

Sounds like you might have bad hardware. Since EB01 I just recently realized I didn't even need to have vzw or google locations checked. I get a lock just using stand alone service. 8/11 birdies locked in 18sec with an error of 13ft inside my house with GPS Status. And that was after a full wipe and rom flash.
good day.

Since EB01 happened I've had a near instant lock every single time.

I had the exact same prob. My gps problems have been completely intermittent, sometimes it would lock on and other times it would not. No matter what rom or radio I flash. But this is what seems to work pretty well.
1. Don't use the gps toggle button on the pulldown. Use the settings.
2. Use google maps v4.7 and don't let it update.
Hope this helps...
Sent from my SCH-I500 using XDA App

I've been using the option from the pull down menu with mixed results.
I've started going into the location & security and enabling/disabling gps from their with much much better results.
Thanks for that tip .

With SC 2.4 ROM GPS was working GREAT!!
I updated to SC 2.6 and I cannot get a lock at all.
With Wi-Fi on the best i can do is get my location and the directions. I can only guess that maybe the clock was changed / tweeked in the later versions.
When I get time I will be rolling back to SC 2.4 ROM.

I have determined it is not a hardware issue as someone else in my area is experiencing the same issues. I updated to EB01 and super clean 2.6. My lock is about 50% now. Either the service is great and locks right on or doesn't at all with the massive blue haze. Someone suggested going back to super clean 2.4?
Once again thanks for all the help guys!

this is the key. and one of the main reasons I went back to DL09 on my phone until the next build comes out.
if you turn it on in settings-->location&security it will work, and then you can turn it off/on via the notification bar for a while, until you reboot your phone...

Is it google navigation having the issue?
I continue to play around with this issue, and am noticing people talking about still being able to be picked up through GPS tools, but not get locked elsewhere. I am assuming that, like me, they are referring to google navigator giving the message "Searching for GPS". Oddly enough, Google latitude is accurately showing my location even when google navigator is telling me it is "Searching for GPS" and drops my turn by turn instructions. I saw one post from cableguy1 to use google maps 4.7 and disable updates, which I would be interested in trying. Anyone know where I can get v4.7?
*Never mind. Didn't pay attention to the fact that my Wifi was on, and the location was a couple houses off. It simply looked precise in comparison to the big blue circle I'd seen while driving. Sorry for the misinformation.*

SC2.4 doesn't have any locking issues for my wife. Good to go there, but not sure if we're just lucky.

2.4 working well
After finding a couple other threads addressing GPS issues, I've noticed people with sc2.4 to have the least problems. Flashed the AIO Odin version, and have had an instant lock so far all morning. Very nice to have google navigaion back

After Flashing to Overcome 1.2.1....GPS is not working correctly.

Ever since I flashed to Overcome 1.2.1 the GPS has been VERY wonky and just plain WRONG. Maps says that I am in the next TOWN which is a good ways away.
GPS Locks are extremely few as well and takes forever to lock on to.
Can anyone else confirm this and or help?

Bumping this up.

When you flashed, did you wipe your cache? With a new rom it always takes a while to reaquire your location. I use the app HereIAm2 from the market to get that first position lock after a rom flash.

Yes I did wipe the caches. Will try that app out if it is free.
Thanks.
EDIT: Noticed that the compass seems to be very inaccurate as well. Weird.

Oh well, that's the least of my probs;-/
i have installed OC 1.2.1 and at one point the whole tab became very sluggish....and all sort of issues appeared such as slow browsing.......then the tab would simply freeze! Reboot did not help at all....
I have since installed OC 1.2.3 with the new kernel and it went ok-ish. But today after rebooting i have all sort of errors (broken messaging service, when i click on the wifi tab to switch on, it says 'error'.etc).
I wonder if others have this sort of probs. I cannot understand how it can work fine for a few hours and then.....kkkkkkkk.
I have the UK tab version with firmware JK5; Also cannot figure it out why it does not show 'overcome v1.2.3 on the build number...it still shows v1.2.1, kernel overcome 97.
I'll have to reflash the lot now.......how annoying.

I am sorry that you are having problems. However hijacking threads is frowned upon here.....
Welcome to the XDA Forums otherwise.

The app is free.
How many roms have you flashed? Maybe it's time to do a factory reset, then flash the full version of the rom/kernal.

Well it did the trick and put me in the correct spot but the compass is still completely wonky.
Oh and this is the first ROM I have flashed. Overcome 1.2.1.

There are apps in the market for that. You want to calibrate the compass, so look for a gps utility. Sorry I don't have one to recommend to you.

Not a problem. I appreciate your advice and welcome any others as well.

One thought about the compass - do you have your tab in a case with a magnetic clip?
Mine works fine out of the leather case, but not when it is in the case.
Just a thought.

No I don't.
To test the GPS to see if there was any interference I put my iPhone 4 into compass mode in maps and did the same with the Tab using the Maps program.
The iPhone 4 was spot on....however the Tab was wrong yet again.
So that means there is no interference.
I am stumped here....and the recalibrate apps did not work either.

Just thought I would try a catch-up.
Since my last comment I moved from Rotos JMIv2 to Overcome 1.2.3 and my GPS also stopped. After 24 hours however, I have got it going through a the use of GPS Status (free from the market) and the LbsTestMode which you can access either through a dialler code or through SGS Toolbox, also free from the market.
To cut the story short, I went from just finding about 3 satelites (with no connectoins), to finding and connecting 10 satelites.
I must say that I am very happy with the current ROM and with the GPS Status program.
Hope this helps if you are still having problems.

I believe that if you dont have wifi or 3g on the tab GPS will not work..

Yes - I've always had the wifi going, but found that unless I had a phone (modem flash) and inserted a sim card, I could never get GPS to do anything.

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.

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.

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.
