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.

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.
I have been discouraged from the Froyo ROMs for a while due to the problem with calls being dropped but then suddenly they aren't dropped. I really like the Froyo ROMs though so I decided to try it again and the first day I experienced it yet again on CELB 3.6. It only happened a couple of times then 3.7 was released and I flashed that and it happened again on the first call LOL. I then started looking through things in the settings and under the mobile data setting I turned on National Data Roaming, since then I have been on several calls ranging from 20 minutes to an hour and have yet to experience this problem since turning data roaming on, some of these calls were in areas that I know for certain I had the dropped and reconnected calls happen before. Maybe some others may want to try this out and see if it helps you as well. Hope this helps some people that have experienced this as well.
Has anyone else tried this yet? And if so, has it made any difference for you as well?
happens to me all the time. kaos froyo, tazz froyo, celb froyo, nonsensikal froyo. Only at my house tho. i have 3 bars there. not sure whats going on there but i have learned to live with it. Wont be long till we are on 2.3 anyway. deal with it for a month. by the new year kaos should have a completley functional 2.3 rom. maybe without camera, but still fully functional.
I've been messing around with the national data roaming for about a week now. When I have national data roaming enabled it doesn't happen, if I turn it of it does. Try enabling it and see if it makes a difference for you too. It's located under settings>wireless & networks>mobile networks
will enable it and see if it happens tonight.
Same here, after enabling it I have had no stopped call issues. Its been about a week, so far so good
Good information, I think I'm gonna try it, but first does this affect my billing at all? I'm on my parents plan and don't want to give them a heart attack if I incur extra charges

It shouldn't but that would depend on what your plan is. If you have a nationwide plan with unlimited data and no roaming charges then it won't. I'd suggest checking on your plan first. Just a thought though lol.

I also have this problem happen on non-Verizon based ROMs such as RCMix.
The call says it's dropped, but the person on the other end can hear everything that's going on.
Then the phone rings you back, but in reality, they were hearing everything going on around you in the meantime.
I almost lost my girlfriend because of it. Immediately flashed away from said ROM. Had the same problem with Froyo ROMs.
May switch to a CM ROM now, if this is a serious fix. Thanks very much for this.
I was hoping this would be a fix - I upgraded to CELB 3.9 a couple of days ago, and turned on National Data Roaming.
Tonight I had the same behavior - temporary call drop and reconnect along with the same symptoms that usually accompanies it (speakerphone mode toggles off, phone vibrated, yada yada).
Confirmed through examination of the (uncompressed) SYSTEM_TOMBSTONE file in /data/system/dropbox/ that yes, the usual cause is present: segfault crash of the "rild" process.
Rats! I was hoping this might provide a fix... but apparently not for me.

Sorry ut didn't work for you.... so far now im at 3 weeks without it happening to me
I have still had this temporary dropped call problem occur just as frequently on CELBFroyo 3.6 with this "fix". And most of the time I'm in my apartment on the phone for hours when it happens, and it sometimes happens more than once during these extended phone calls.
Just as has been described before: the phone looks and acts like the call was dropped, I can hear nothing but the other person can hear everything, and then after several seconds everything is back to normal.
Oh well. Thanks for the suggestion, though.
Very interesting to hear others have been having this problem. I had thought it was due to my bluetooth earphone, because it used to happen to my wife on her old earphone with a standard cell phone. However, last night I lost my earphone and the same problem occurred while on speakerphone. Although annoying, most of the time I just deal with it. I just installed radio version 2.42.01.04.27 hoping it might help. Various versions of CELBFroyo (currently using 3.9) have done it. I will let you all know if this helps and keep checking back on this string to see if anyone else finds a fix.

Seems like its touch and go now. Works for some but not for others. I haven't had it happen to me in 3 weeks now but this hasn't worked for some others where some it has. Im using the new sprint radio now, I don't know if maybe it has anything to do with what radio you have too? I just flashed this radio about a week and a half ago though. Before that I was on the older verizon radio... not the one from july ota though... the previous one.

Thanks for the leads to the other threads. I had not seen them.
I have not had a chance to test with the current radio installed (2.42.01.04.27), but plan to tonight. Is there a newer radio for the Eris? Looking at the version numbers of some I have seen referenced would make me believe that there are newer ones. Where do you download these?

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.
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.

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...
I recently started using my wifes old fascinate after I broke the screen on my Droid Razr. I had rooted it for her in the past and was running AOKP ICS. The phone was performing well but gps tracking seemed to be seriously lacking. So messing around with it I noticed it was running the ED05 radio. I figured i'd upate to EC09 and see if that would improve anything. I used to Odin to flash EC09 rebooted phone and I had nothing 0/0 fix/sats in GPS status. I toggled it on and off and tried resetting GPS data and let it sit for a long time and got no lock.
So I said what the heck I wanted to update to Jellybean so lets flash a new rom and see if the clean install helps. So I flashed hellybean from recovery and the rom runs great but still no GPS. So i'm thinking okay..weird...let's try another radio. Tried flashing EH03 and same issue. So figured i'd flash back to ED05 and hopefully that would do the trick. Well now I'm back on ED05 and the phones been sitting for 10 minutes running GPS status and still hasn't found a single sattelite.
Any ideas of something to try? I use GPS for tracking a lot and really want to get this thing working. I am out of ideas.
Maybe you should try the app GPS Test by Chartcross. Install it, go to settings, and hit Clear AGPS.

Thanks for the feedback. I eventually got it to work and felt like an idiot. The trick? Walk outside...
I did a full factory reset and reflashed hellybean tried some more radios and was about ready to throw the phone at the wall when I said what the heck lets just go outside and see what happens. Walk outside and was locked within 10 seconds.
For some reason the fascinate GPS will just not work sitting on my desk at work. My razr had no issues here so I guess that's why I was expecting it to at least find something. I guess this GPS receiver is just weak.
The wavelength GPS is on has the property of not being able to go through buildings. While this phone's GPS is pretty rotten in this case it's not really Samsung's fault.
