I was messing around in the Android Apps and Games forum and found this post. So then I wanted to share it with you guys.

My question is... could this be used in any way to improve our development?
As if this "fix" could be built into our ROMs or radios or SOMETHING to connect to a GPS quicker?
Just a thought...
I think the agps pstch does the same thing. Also GPS status from the market can do the same thing.

I think all these GPS fixes dont do anything personally....a long time ago someone suggested to get a satellite fix, then reinstall the ROM and it will lock almost instantly every time. And it has been working for over a year. I have done it to 3 different thunderbolts besides my own and worked. I never use these "fixes." Im no pro at this software stuff but trial and error is my expertise and when it works perfectly every time on multiple of the same device, id say thats the best way to do it.

I mostly agree. I just went through this process, having gone from a Sense-based ROM (BAMF SOAB 1.4) to an AOSP-based ROM (Thundershed 1.6). Despite the new ROM having the AGPS fix baked in, I still wasn't getting a GPS, so I made a nandroid, flashed back to an old nandroid I had of SOAB, opened up Google Maps, to get a satellite, then opened up GPS Status (from the Play Store, free) to find the strongest lock I could (9 out of 9 satellites), then immediately went to reboot into recovery and restored my Thundershed nandroid. I then opened up Google Maps then GPS Status again, found I was locked onto 10 of 10 satellites, and I was good to go.

I agree with him. GPS don't do much anymore. The 4g signal does more than the GPS. You could not run a GPS app without data connection. basically all they use gps for is to find exact location. And soon i think that they will probably discontinue gps in a phone!

I am using ROMeOS and can only get GPS to connect 1 out of 20 tries. It is beginning to look like It is a hardware issue since so many people are having trouble and they all have different situations-different ROMS.
Is there a particular ROM that is having luck with GPS?
Hi,
there are several threads on the GPS issue. It's not hardware. Search for "HTC GPS Tool" and run that. It will get a lock within a few minutes and after that your other programs should be fine.
I have switched to NATF's ROM and am having better luck. If it is not a hardware issue than I bet one of the cooked ROMs is better than another for GPS.
What I dont know is how well a particular ROM works with GPS. I could flash every ROM and find out for myself, I could read all 200 posts in every cooked ROM thread to see if anyone is having good/bad luck with GPS or I could ask;
"Is there a particular ROM that is having luck with GPS?"
I'll go first. I am now using NotATreoFan's ROM http://forum.xda-developers.com/showthread.php?t=444784 and am now locking on to GPS with in 1 to 5 minutes.
Any other ROMs working better for GPS?
I am using PROven's 1.03 and get the lock every time in about 10 seconds (with latest iGO).
I applied some tweaks mentioned in GPS lag threads.
I've used both NATF and ROMeOS and both I get a lock within a 1 minute if that much. Before I ran HTC GPS Tool, it took a very long time to get a lock. After I ran it, I can now get a lock in TT very quickly. I also get a lock in Google Maps fairly quickly.
One other thing I did do was within the WinMo Systems, there's an External GPS setting. I changed the hardware port from Com4 to Com1. Not sure if that helped also. Give that a shot.
My Vibrant's GPS only works fine with Macnut R10, no other version of Macnut or any other ROM (Team W,ASOp,Axura,JK2 stock, etc). Only works with Macnut R10. I checked the GPS files and they seems to be the same, so I'm going crazy trying to figure out what else is different so I can make my GPS work on other ROMS...
It's like this,,, After Flashing any ROM I go to lbsTest, Delete GPS Data and then Test GPS,,, I'm using the same exact location to the the test with all the ROMS, after 1 minute I only get 2 or 3 birds, but non in use, after 2 minutes I get between 6 to 10, but still non in use., after 4 to 5 minutes I get connected to 3 or 4 and thats it...
Now, If I flash Macnut R10, and do the same steps,,, in less than 3 seconds I get 10 birds in view and in less than 10 seconds I got connected to 6. This happens every time I do the test.. I have done the test several times with the same results.
At first I though it was the kernel... but after flashing the JK2 kernel the GPS still working just fine.
I'm running my Vibrant on At&t if that can help to find the answer...
Thanks...
PS... before someone else say it... Yes I did the steps to Delete the GPS Data, change to Cold start, get the birds, reboot, etc,etc,..... that does not work as soon as I restart my phone its gone...
Thanks
Interesting! Considering my only disappointment with this phone is the GPS and I am having the same issues with Obsidian and every other ROM, I will download Macnut, that I haven't tried.
Did you Odin in between ROMs?
most of the time settings carry over even after the system has been wiped. Odin is a surefire way to get a clean install on a phone.
I've run most ROMs and on all of them my GPS has worked without a hitch, I can usually get a lock in less than a minute at the most.
If it's not working out for you at first, drive around in your car with GPSTest running so it can re learn. You probably don't even need to clear out GPS data under lbstest

Be sure is R10, that's the one that worked for me
no one?..............
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.
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...
Okay, I have done the following things:
1. I have soldered the connection inside the phone. (Yes very nicely I might add as I solder a lot at work.)
2. I have the Sub-Zero build 75 kernel.
3. I am using Slim ICS Rom from the android development forum.
Why in the hell does the GPS lock on instantly sometimes, and other times I have to restart the phone 20 times before it will even thinking about locking on again?
What is wrong with this phone's GPS? What else can I do to get this GPS to work all the time. The programs that "clear the GPS data" or the phone code that does it, does not work. There is no message and no sign that it cleared anything. The "secret code" program just crashes of course, when I try to use the GPS clear data.
Is there anything else I can do, besides throwing this phone against the wall. I actually NEED the GPS sometimes because I travel a lot, and I can't even rely on this phone.
Here is how I understand this:
Since we never got an official release for gingerbread we won't be getting one for ICS either. The problem is that all releases for our phone for GB+ are hacked together from the source released for the other phones in the Galaxy S family. Also, since the actual guts are slightly different between models, we don't have the actual Samsung drivers for these releases on our phone.
Another problem is that the GPS chip they used on this phone sucked and was sub par at best when released. Most vibrant owners had issues.
The only way to guarantee the best GPS performance on this phone is to stick with the stock Froyo firmware. Everything else is hit or miss since we got the step child phone off the Galaxy S family.
I was lucky enough to buy my vibrant several months after release, so my GPS was revised by then and better than the release models, but it still flakes out on custom ROMs sometimes.
For now, I am on Slim 3.5, and sub zero 80 kernel.

GlobeSpy detailed this in his post here:
http://forum.xda-developers.com/showthread.php?t=1550327

I flashed the yags and experia GPS fixes, made sure to install angryGPS and faster fix.
Angry GPS settings changed to MSBASED, cold start, and Xtra=off.
In supl settings, I selected Google server.
In Fasterfix: selected custom and set to us.pool.ntp.org
After rebooting the phone, open GPS test and let it lock birds.
After that, I can exit out of GPS test and run navigation. GPS will lock later in day too.
The same settings worked on the stock slim kernel to, so sub zero isn't a requirement, but I have made it work on both kernels. In my expewrience the stock Slim kernel worked better for GPS.
Hopefully this helps, but each phone is so different, the results are not guaranteed.
It really is too bad that Samsung dropped the ball on the GPS in this phone. It's the only weak bit of the device.
