GPS was solid but now? )-: - Vibrant Q&A, Help & Troubleshooting

So a little about my phone. I am running a custom ROM Fusion 1.1 with a custom Kernel from Team Whiskey Core V3 2.1 also have OCLF. My phone right after flashing the new ROM seemed to lock on quickly to several Sats 5 plus every time. But for no reason and with no adjustments to the default settings I now have a very hard time locking on to any Sats. Takes 10 plus minutes and only can get a few to lock.
So the only things I have changed on my phone recently is trying a few different Kernels. Would this even effect the GPS sat locks at all? I would think not but??
Anyone have anything new that I have yet to read about that they have tried that seems to make the GPS better?
My phone's GPS might just suck who knows.
Thanks in advance!

Did you try digital toddys fix?

Yea I did.. Just went outside and switched to Cold then delete GPS data ran fix for 10 minutes and got a lock on 4 sats. Switched back to Hot and didn't seem to help much.

You did the reboots and everything?
Odd man, if that didn't work I am at a loss. Hopefully others can chime in for you.

I would think the ROM is what affects GPS signal the most. I was running Bionix 1.9 with KK kernel and the GPS was money. Now running Obsidian V1 (didn't switch to V2 because I read people were having GPS issues on it), and GPS still works great. In fact, when using Car Home, it shows the exact street address I am at.

from what i understand, yes a different kernel can affect gps because the kernel contains the drivers. it is my understanding that this is why the 2.2 roms have working gps now: an 'official' kernel was leaked and the gps drivers were pulled from it. however the rom will also affect gps. for example, i was running bionix 1.9.1 and gps was great, flashed bionix final and gps went to ****, flashed fusion 1.2 and gps was working again.

GPS Question

So I've got a Vibrant running Stock 2.1 with the JI6 OTA update. For some reason, like most others, the gps has never worked nor is it working now. I've done the quick fix for stock users by setting my phone to MS based, switched it to supl.google.com with 7276 for the port and can now see about 9-10 gps's at any given time, (and to add the compass works amazingly) the problem is that even though I see these satellites I never get an official lock. I've done gps test and even the performance test through *#3214789650# and I cannot get an official lock. I've since switched to and from these settings and the original settings with no change, and when it is set on the original settings I only see 1-4 satellites and never get a lock. Anyone have any suggestions or am I just boned till 2.2 froyo and pray that when that's officially released the gps will officially be fixed? Thanks if you can help ^_^
I recently installed the latest bionix ROM and the GPS was pretty much fixed. Locked on in seconds and was not as wonky as it was before.
I suggest you give it a try.

There seems to be a minority, myself included, for which the JI6 hasn't improved GPS performance. I've tried falling back to JFD and upgrading to the stock JI6, as well as other ROMs, including Bionix 1.9.1. No joy.

[Q] GPS signal lost on multiple roms

So I've done a lot of searching and haven't really found anything definitive. I've found that with some roms I'll lose GPS signal after a certain amount of time (say 10-30 minutes) and have to turn GPS off and back on or reboot the phone. I saw something about flashing a different radio may make a difference. Kinda just wanted to see other peoples thoughts on the issue or if maybe there is something else I can do before I go flashing a different radio.
Currently running CELB 4.1 and baseband 2.42.01.04.27 and I have the issue.. I've had it with most of Tazz's roms as well. KaosFroyo is the only one Ive used that I've never seen the issue with, but I'm really diggin CELB right now and this is the ONLY issue I've got with it.
Have you tried GPS status in the market? I know it will help you lock in a signal, so it would make sense that it would also help keep your GPS locked in.

I have now.. I did the reset and download options in the program. Too bad this isn't something I can quickly test. I'll report back with the results. Thanks!
I have noticed this as well. Last time it happened to me it was 4:30 in the morning, and the "GPS lost" message came up about 180 seconds before I had to make two freeway changes in an area I'd never been before. (CELB 3.9 and same radio as your case). Fortunately for me I had reviewed the route, so I more or less knew what to do.
If I recall correctly, it has always happened after the Nav app had been running for a fair bit of time - at least 30 minutes or more.
However, I don't know if it is something about the root ROMs or not - I started using rooted ROMs back in March or so, so I really don't have a tremendous operating baseline on stock 2.1 ROMs to compare it to. Maybe it is a problem there, too!
If I recall correctly, the last time it happened, I just pulled up GPS Status and asked it reload the aGPS state (without exiting the Nav app), and the Nav app seemed to gracefully recover.
Annoying? Yeah. I don't know what can be done about it, though - like the "undead calls" problem, it happens so infrequently that it is hard to know whether or not a ROM change actually fixes the problem.

I had the same problem with every 2.2 rom I used GPS with. I decided to go back to 2.1 because I have been needing GPS alot more often lately but I havent tested it out since I made the switch. I'll try it out today and report the results tonight.
This same thing seemed to happen on the 2.1, CyanogenMod 5 based ELB by Conap as well. If it is happening with all of the 2.2 ROMs, I wonder if it's just a CyanogenMod issue?
See http://forum.xda-developers.com/showthread.php?p=6812308#post6812308 (this was not the only person reporting it, if you search that thread.)
I really don't think it's ALL 2.2 CM roms though. I've gone on 7 hour car trips with Kaos Froyo without a single drop.. to and from. I've seen another theory somewhere around here about it being certain hardware revisions that act this way with certain software builds. At lease we've got a thread dedicated to this issue now.. maybe we can get something figured out.
Still don't know if the GPS status program helps.. I left navigation turned on for a bit sitting in my house and it stayed connected for the half an hour I left it, just don't think that's gonna be an accurate test with not moving around and all. If it doesn't work I will try a different radio.. I saw somewhere one guy had good luck with a specific older version radio. If that's what it comes down to I'll try.
I have been having issues with the GPS working on both of my phones while using 2.2 roms. I switched to 2.1 a few days ago and I used the GPS on my way to work this morning and didnt have any issues. I also had to flash Senseable a couple of months ago while on a road trip because I was tired of loosing the GPS signal every half hour. It may be a CM thing.
Im having the same issues as well. Haven't found a fix yet..
I've had this issue, after I flashed KaosFroyo(v36), and XTR(4 i think). I recently unrooted using Flashback21 v1 and flashed with the radio included. I have gone back to xtr 5 now and have had no lost gps in over a week. Don't have a clue as to why. hope it helps someone.

give us another update. is the gps problem still fixed for you? Thanks!
I have flashed the radio directly with the verizon zip file that is around and I still get inconsistent results But it always drops a signal eventually in about a 1/2 hour

I've seen it on several ROM's as well. From what i've messed with, it doesn't seem to be dependent on the autokiller memory preset, radio firmware, or amount of overclocking i'm doing. It doesn't seem to be dependent on how many programs are running either. I usually have nav and pandora running while i'm in the car, and sooner or later, the gps poops out.
I feel like it seems to happen less, now that i'm back to using the on-demand governor. but that could just be in my head.
I've had to go back to a 2.1 rom because of it. Its very annoying when the goa signal gets lost right before the exit ramp.

Im thinking of going back to a 2.1 rom as well...
I have also seen the same results on any 2.2 or higher rom. I have since returned to XTRRom 5.0 and have not had a single problem with GPS on any of my jogging runs. I definitely think it is a CM thing. At least on my phone.
Using kaosfroyo v39 and I flashed that sprint phone radio on my eris and haven't had any gps issues. In fact, just the opposite. Mine would lock up before the v39 and the radio flash
I flashed that radio as well and today not one issue at all. Will test more tomorrow
I'm using the 2.42.02.10.29 sprint radio and still seeing it drop out.

Today I even flashed back to the July 2010 version (2.42.01.04.27). the gps dropped out almost every 5 minutes while i was driving around. that's the worst i've seen. So i flashed back to the 2.42.02.10.29 sprint radio again. I haven't seen very good navigation performance on the v1.1 gingershedbread overall, actually. my position on the gps nav doesn't update very often, although it seemed like the voice instructions were still pretty well timed as usual.

Rom Kernel Modem, Stable with GPS.

I've tried literally every Rom for my vibrant as they came out over time...and and my GPS sometimes work and don't. Mounting and random little glitches. The most stable rom I've used is 2.1 Stock, and I justed flashed 2.2 Stock. Whats everyone opinions? I thinking decent GPS. XD

Try using gps aids from the market.
Sent from my SGH-T959 using XDA App
Have you tried digitaltoddys fix? It's in the general sticky (signature).
Trigger works perfect for me.
The Trigger or the Axura both provide pretty good GPS. Both, I get 10-15 sats with 5-7 lock 20-40 sec average.
Also, GPS aids and the digitaltoddys fix both work as well. You just have to experiment with them. Plus, when you first test (after fresh flash) you need to let it find for about 3-5 mins for 1st run, after that flawless.......... at least for me
GPS seems very strange in my experience and may depend on your location. Personally I've found KB1 and bionix v 1.3 or trigger to be the best, while others have issues getting locks on this modem. It may be due to hardware differences, but it's tough to narrow it down. Best bet is to experiment and see what works best for you.
I've been using the stock 2.2 and GPS locks instantly. No Mounting issues or data problems. Completely Awesome.
I've using axura without any issue. GPS usually lock within a couple of seconds.

[Q] GPS Broken Broken

Hello well not sure but I think my GPS is "broken broken" like maybe something hardware related but just wanna to check with you guys first instead of doing anything drastic.
I think I first noticed when i was on a build of trigger(cm based) that the GPS kept searching for location and unscessfully tried the CM7 GPS script. I then just decided to Odin back to stock and getting the same results GPS wise. I also tried Nandroiding back to a ROM that knew GPS worked when i use to use it(toxic w7 clone) but still no luck. Also worth noting that while on Stock Odin I tried some different Market based GPS fixes(GPS Restore GPS Aids).
Any help would be appreicated thx
some people have working gps, some dont. mine kind of works but it takes forever to lock.

Did your GPS work in the past?
I used a 2.2 build of Trigger a little bit back, and it did the same thing to my phone. I have a "fixed" hardware GPS antenna (since I did the FFC mod, fixing the GPS at the same time was a piece of cake), so when I suddenly couldn't get any GPS signal, I knew something was most definitely up. I tried the sgps "fixes" to no avail.
Eventually I flashed CM7 (since gps wasn't working either way, at that point), then Odin'd to stock, then flashed Bionix 1.3.1, and suddenly at some point it fixed itself. Now my GPS is back to working on CM7, as well as 2.2 roms.
So, if your GPS used to work fine, there was something software-wise which screwed it up.
Do yourself a favor and call TMobile. Tell them that your GPS doesn't work and you'd like a replacement. Do it three times and get a completely different phone for free.
The Vibrant is a POS at best.

Hmm.. i did see a post where someone said it took 5 minutes to get a lock maybe I'll try the GPS test again for longer period.

Sorry bout that I should of mention that GPS was working in the past, never tried Bionix I'll see if that does the trick.

Yeah this what I meant by drastic but probably my only real solution, wonder how that works though im pretty sure I'm paying for some replacement/warranty but that's only if they find out it is broken or defective right?
So glad i bought a Vibrant for my birthday as my 1st smartphone
Well I think I made some progress here, I Odin back to Eclair and to Bionix. GPS still wasn't working but GPS Test shows that there are some Satellites "in view" but not "in use" weird...

GPS Problems in either Euphoria and Passion on 2 vibrants

I know there's plenty of GPS problems with this phone, but after reading that GPS works in both the roms i've tried, i think im doing something wrong. This is where i'm at:
After using both of these roms on 2 different vibrants, i can't figure out for the life of me why i cant get the GPS to do anything at all on these roms.
I've used ODIN to go back to stock, and then tried flashing the roms but with no luck.
I dont have any clue how to use Angry GPS either, so i haven't messed with that at all. If i need to change some settings within the app, please enlighten me.
Thanks for anyone who helps me with this problem. The only Rom i know of that i have 100% working GPS is with Team Whiskey's Bionix-V 1.3.1.
Anyone? I dont want to be pushy, i just wanna figure out the problem.
And on a side note, i know i posted in the wrong section.
GPS works but it is also a work in progress as no one knows what is really going on with GPS in the Vibrant. The ROM seems to have little effect on weather the GPS works but the "kernel" that underlies it is where the effort is being placed for a fix. While the GPS works on all the kernels it eventually stops working after some time. It is believed to be an issue with how Android starts and stops different services to save power.
Most users have reported great GPS using Kiss 2.2 kernel in combination with either of the Team-Passion Roms (Passion, Euphoria). The most recent kernel is Kiss 8.2. Get it here:http://team-passion.com/index.php/downloads/galaxy-vibrant
For info on each kernel see here: http://team-passion.com/index.php/forum/2-about-team-passion/283-test-kernels
Keep in mind that the developers in my opinion have been working on these ROMS and Kernels like it was their full time job. And they are determined to make GPS work consistently so give them some encouragement to hopefully keep them motivated as they are likely our only hope.
Passion is a faster more responsive but Euphoria has more customizations baked in. The kernels are interchangeable between these ROMs but they have different performance characteristics.
GPS working after deep sleep on Euphoria
After going through 10 ROMs and 20 Kernals I think I may have a semi working GPS. Running Euphoria RC2.1 with stock KB5 modem and gingerbread bootloaders. Installed these gps fixes
http://forum.xda-developers.com/showthread.php?t=1550327
Ran ultimate cleaning script then flashed Glitch then the subzero kernel in the same recovery session
CM9-vibrantmtd-Glitch-V14-B6.zip
cwm-subZero-vibrant-1.1VC_build61-CFS_BLN.zip
Lock immediately after boot with angry gps and phone has deep slept multiple times and gps picks up after granted after 50 seconds
I really appreciate the help guys, the Kiss 8.2 kernel fixed the problem in the Euphoria 2.1 ROM. I get locks within 10 seconds, and also better battery life.
So now as far as im concerned, this is the best combo there is.

8.2 did the trick for me. Locked up in under 20 seconds, and I'm inside my house (by a window) Don't know about deep sleep recovery, but I'll let you know.
You really need to change to Chimera v2.2
