It's been a while. I miss my GPS and compass working right. Any Ginger roms made improvements to GPS or compass accuracy since last I looked at roms in early summer?
If not, I'm ready to go back to Froyo.
Short answer, yes.
Long answer, search
I searched and read for a half hour. Only thing I see is that GPS works, sorta, if you don't turn it off and compass is still wonky. Nothing new I guess.
stable cm7 with streamline kernel will give you really good gps. first time I was able to use navigation on gb rom. my phone is from original june batch so that saying a lot. compass never really worked on our vibrants.
Yea compas dont work but gps on cm7 with streamline works great ccan be turned off and on at will without adverse effects... its performance however is a bit subpar.. takes a Long time to lock and can sooometimes lose a lock temporarily

thank you. Just wondering. I was trying to use google sky the other day and it was completely unusable. At least it worked well when I was on froyo.

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.
Hi,
I've been constantly having issues with the GPS on my vibrant. I got a replacement vibrant from t-mo about 3 mos ago because the GPS rarely locked on my original phone. This new phone's GPS worked fine for a while with the stock Froyo ROM. It always seemed to lock in less than 1 min. After a few weeks, the GPS stopped locking reliably for me.
I tried an update to CM7.1 and didn't see any improvement with the GPS.
So, here's my quetsion:
1. What is the best ROM for GPS usage on the vibrant?
2. Is this GPS Fix still relevant?
I'm running CM-7.1.0.1-Vibrant.
Kernel version - 2.635.12-gdf10700 [email protected] #1 (that's a mouthful).
Thank you.
If GPS needs to be absolutely 110% working, then MIUI (if you want GB) or any 2.2 ROM will suffice. As for the other GPS fix relevancy, it can be really hit or miss. On some GB ROMs it works, on others it doesn't. It's really by chance that the planets align and the powers above grant you vibrant with working GPS

I have a similar problem, I found a solution in ICS ROM.
When you turn on the phone, before it finds a network, you need to run any diagnostic applications of GPS, for example GPSLB TEST NB and immediately start the GET POSITION.
You will find that it finds satellites at once. Turn off the software.
you have GPS working until the next reboot...
The vibrant has always had gps issues. Theres a fix somewhere i cant remember where. Havent had a vibrant in awhile

I never managed to have an accuracy better than 140 or 150 feets.

That means it's quite hard to use GPS while walking or driving in the city, because it will randomly jump from street to street.
Am I the only one with such poor accuracy?
Search the dev boards and you will find this to be a common problem for the vibrant. There are several fixes for non-working gps, but I don't know that I've ever gotten better than what you posted.

Yep, I did both sofware and hardware fix. That's a shame...
What ROM are you running? The ones in your signature? Check out the link in my sig and see if that works. Might also want to download Fasterfix from the market and change it to something closer to Italy.
Yep, all the details are in the signature... thanks I've already read that guide in your sig.
I'll try with Fasterfix (My current SUPL address is supl.sonyericsson.com because supl.google.com seems not to work here in Europe) and will let you know.
What's your GPS accuracy?
When on Froyo, I can get it down to 20ft and under. When on ICS usually about 40-60ft. Now that we think that we have figured out the GPS bug that should get smaller.
My GPS didn't want to work the best on CM7 either. It did work, but not as good as other ROMs. I'm running Euphoria and locks are pretty good, 20m at most and usually in 10-15 seconds. Worth a shot.
I had no luck with Fasterfix. I may want to try ICS Euphoria as soon as it goes out of RC-cycle (probably with the next release).
You should give it a go now. Not really sure what they could imporive on at this point other that some data storage issues. But really everything works as it should. No mute/unmute and GPS issues seem to be linked to Launcher Pro.

^^^This. I cannot think of an issue that I've encountered with it. Once you go ICS, you won't go back
I hope so
We'll see in the next weeks
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.
http://forum.xda-developers.com/showthread.php?t=1239713
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 searched through some threads and I couldn’t find a definitive answer on this that was recent.
I am currently running ICS Euphoria on my phone, but I recently started having issues with my phone missing calls intermittently. What happens is I will get a voicemail from a call that never came to my phone (no ring, no missed call). Since it has been awhile since ICS was released, I figured this would be a good time to upgrade to JB.
I’m looking for a slim, fast, and functional version. Don’t care about customization, just need a good daily driver. Specifically I’m looking for a ROM with decent GPS (as good as it can be on the vibrant anyway).
What do you guys recommend?
Slim bean, I know the final jb41 build had solid gps, not sure about jb42 beta builds. CM10 stable also hassolid gps.
Sent from my GT-P5113 using xda premium
Slim Bean seems to come highly recommended, but when I looked at it originally the big complaint was no GPS, maybe that has changed?
I have stayed away from CM roms since they seem to be more on the bloated side of things, but offer lots of customization. Really what I'm interested in is a fairly vanilla experience that runs fast and doesn't eat battery like crazy.
There are some flashable files that will help gps, yagf2, experia gps files and gps wrapper. IMO, slim is your best bet.
What you don't know could fill a book.
You can look at the thread I started here with the same Q and my experience: http://forum.xda-developers.com/showthread.php?t=2040685
Bottom line (for me so far) is that NONE will have a working GPS,
and if you do get a gps it will eat your battery with all the Kernel Wakelocks caused by the gps.
Again, this is MY experience, I know others have better exp, would appereciate if you could update what you found...
BTW, on Bionix (Froyo) my GPS worked OK, so I don't think it is my device, but who knows...
Interesting points guys. I have had a few different roms on this phone, and the best gps so far has been ICS euphoria.
I think I'll give slimbean a try. I still need to do the little hardware mod for the GPS as well. Hopefully this will net me somewhat reliable GPS.
I have a copy of PA 2.54-360 with ICS GPS files that jrongi1 sent me. If you would like it you can PM me.
The GPS worked great for me!
And I still got love for the streets..
Gps is tricky with our phones. Each is different it seems. I have an orriginal T959 so I did the harware fix. The hardware fix combined with my use of angrygps.apk. I use "supl.sonyericsson.com" port 7275 in both gps.conf and angrygps.
I dont have DS issues with 4.1 or 4.2 roms. never had.
I installed cm10 and kept the gps.conf that came with it, it looks working OK, not the best signal but that might be phone fault.
Its IMPORTANT to use port 7275 in the supl server and not 7276 as some other posts suggests, the 7276 port was the reason for the kernel wake locks and GPS drain...

RemICS-JB v1.0(Team Remics) has good GPS. Doesn't lock as fast at first. Then after few seconds it kick ass. Great rom may I say.
