i originally posted this in the radio thread, but after finding this on twitter:
Twitter / Josh Fleischmann: Fixed froyo/incredible gps ...
...i thought maybe i should post it here because it might be a bigger issue. i upgraded my radio to 9.01 last night, and this morning found that while standing still my gps location is off by a good bit (2-3 city blocks, small town). when moving it seems to be much more accurate, but as soon as i stop it's way off again...
i downgraded back to the official 2.15 radio to see if that would fix it, but it didn't...the issues persisted. so i tried the fix above from twitter...that got it a little closer, but i'm still off by a block or two.
anyone having problems today, or have any ideas how to fix this?
oddly enough, upgrading back to the 9.01 radio after doing the twitter fix (unmount gps, power off, remove battery) seems to have fixed it...either that or it randomly fixed itself. very strange...

Hi all, i have tried to find similar thread with "search" before opening this one, but this function is not working right now to me.
The problem: usually my Artemis integrated GPS works very very well, for weeks (cold fix in not more than 2', also without downlaod of efemeridi, and hot fix very very fast, with 7-10 satellites hooked). But in some days/weeks/periods the gps doesn't work well. In particular the cold fix (first fix) needs some minutes (5'-10'), and once the fix happened, the signal of each satellite hooked is really poor, or the number of satellites hooked is low and instable; for eg the gps hook not more than 3-4 satellites, and loose and find the signal continuously. And also other fixes during the day ar slow if made just after few hours from first one.
The strange thing, as said before, is that usually the gps works very very well, for weeks. But expecially during the winter it happens that it works bad for days/weeks. And without any operation after some days/weeks it turn working very well again.
The issue don't seems to be linked with bad weather days. Can it be related with seasons and relative different position of satellites in the sky?
Untill now i never found other guys with a similar problem on their Artemis device. So now i ask here for support.
Which could be the problem? And which is the solution?
Thanks in advance for support!!
PS i use WM5 original. The issue happened since first year of life untill now (i just did an hard reset). And the issue happened both with TT6 and TT7 (just installed).
Yeah, I know that seems to be a pretty common issue with the Desire HD, but hear me out!
I had my DesireHD for about a month and I love it. Been trying various CustomRoms and so on. A week or so ago I noticed that my GPS is no longer working. I think I was using CM7 back then. I decided to flash a different rom to see if that fixes the issue. Well, unfortunately not. I then tried a few different Radio images, but that also did not fix the problem. I just can't get a fix. It did work fine with different ROMs previously though. I went back to the very first RUU update (which includes 1.32. or something and the radio) BUT I still can't get a GPS fix.
Is the device "broken" or is there still anything I could try? With all the wipes, restores, different ROMs, I should have "replaced" all software parts that could cause issues, right? I read that there is something like GPS cache that could be deleted, but not sure if that's done with full wipes etc, anyway?
Any suggestions? I'd hate to send the device in as it's likely going to take "forever" to get it repaired.
Thanks in advance,
BoB!
Hi Bob.
How long do you wait for it to get a fix? As far as I know, the first time whenever you flash new ROMs, it will often take much longer than usual. After the first time, it will normally take about less than a 2 minutes.
Got try using FasterFix to set your ntp?
Do you install GPS Status from the market to perhaps monitor the amount of satellite found by your device? You can also use to download A-GPS data.
I used to suffer a lot of problem waiting to get a fix (I hate waiting especially when it comes to GPS). But now it seems to be behaving. Lol. Could get a fix between 5-15 seconds. Now at most it will take is still less than a minute. Hopefully this will go on. Lol.
Hi, I had alot of problems with my GPS. Tried with different radios and ROMS. Found satelites but could not get a fix.
Unrooted and sent my phone to a repair shop. They found out that there was a problem with the GPS antenna and changed that. Will get my phone back over the weekend. Hopefully that fixed the problem.
This could also be your problem. Unroot your phone and send it to the guys that now what they are doing
I was out using my phone GPS on 3 local golf courses and noticed my GPS was always 10-20 m off from known distance markers on the course. I had been using my GPS and a few different golf apps early in the season, March and it was always right on 0-2m difference. I did update to the newer radio since march from 7.28, would this cause an issue? I am going to try GPS status app and reset Agps data as suggested by a few others, but thought I would ask if anyone else is seeing this consistent offset?
I am now using
CM7.1RC
Incredikernel 6/272011
radio 2.15.10.05.06
Very well could be the new radio. I'd flash back to 7.28, I've found it to be the most solid.
i've had all sorts of GPS issues with cm7 and the newer radios...cardiotrainer and google nav (and maps) always seem to jump all over the place. this was with the newest gingerbread radio, i've also used either 11.19 or 09.01, i can't remember which (i might have even tried both).
i just flashed back to 07.28 (from the newest gingerbread radio) in an attempt to resolve it. i'll let you know tomorrow what i find when i drive into work...
edit: after just going outside, i don't hold out much hope for this having fixed it. it's almost like every time i turn the screen off or put an app in the background, i lose gps lock. if i'm in maps and it sees my location, and i go back to the home screen then back to maps again, it'll see me a few yards away then quickly jump back to my current location. it's really annoying...
I am going to give that radio(7.28) a shot as well. Any update on your GPS, did you get a chance to try it on your commute?
I've got a really short drive (only about 5 miles or so), but the results so far look promising. As soon as I pulled out of the garage and opened maps, it got a gps lock within a few seconds. Tracked me all the way to work and seemed to be spot on the whole time. Even checking into foursquare once I got here it was on the mark more so than it had been lately.
Like i said, promising ....but I don't wanna say it's fixed for sure yet. I've got a longer drive coming up this weekend that ill test it on.
Also, I'm wondering how it would fare if I were to turn the screen off (like I would if I were running with cardiotrainer) ...
EDIT: Well I took a drive with gingerbread radio 2.15.10.05.06, had me off the road on google maps. Flashed 7.28 and had me in the correct lane. I will check with my golf apps tonight and see how it is looking.
Dan
Good to hear, I am going to flash old radio in an hour and try on the golf course, and I will track in google maps as well and see. I'll post tonight again with my results.
Thanks for the update

GPS working with the 7.28 radio. My GPS went from 10-20 yards off any marker on the golf course to 0-3 yards off.
Same here, I think.
Standing inside subway, went to check in on foursquare...says I'm 43 feet away. Other radios would consistently have me anywhere from a few hundred feet to a half mile or more away.
Seems 07.28 is the best radio for GPS.
On my long drive this weekend (2.5 hrs roughly), GPS was pretty much dead on the entire time.
7.28 seems to fix GPS issues, at least for me.
i tested on to road trips over the July 4th weekend and GPS was working perfectly. I guess we will have to wait for a new radio from the upcoming Incredible update everyone keeps mentioning. Guessing the leaked Radio still has some bugs to be ironed out.
Perhaps I spoke too soon, my run today with endomondo was off by a bit but only in one direction (ran around a track, had me on the track for the length of the field but the turns on the ends of the track were off by about 10 feet).
I'll check it again tomorrow if I get a chance to run...
Edit : much better today. Yesterday must have been anomaly, although I did clear the gps earlier today. Perhaps that helped.

Have you been ok since? Endomondo is jumping all over the place again today on my run...
Seems clearing gps data fixed it, at least momentarily. Went into gps status app, cleared gps data then downloaded a gps data, then did a quick reboot and walked a mile...dot was spot on every time I checked it.
I'm having a problem with my GPS saying its working but not actually picking up any Satellites. I'm using LeeDroid 5.1.0 and its not working with any GPS program.
I have tried testing it with GPS Test and get the attached image below.
Hi,
Posts here goes into some detail - seems to be some doubt whether its a hardware or software issue at the moment (see the last post in the thread about my recent testing).
I'm having mine replaced by the carrier in any case (when they finally receive stock), as it appears worse on some hw than others.
There are some fixes around since you're rooted, which change the gps.conf that might be worth looking for. I think they are linked in the ARHD thread somewhere.
If it is hardware, could be something like the issue I've read about on the DHD, where the contacts for the antenna are not connecting properly. Since the case is sealed, not sure it is one that can be fixed by the end user though.
Having said that - even though my GPS was flaky, it did lock on to some satellites - the issue was that it randomly locked on to a different 3 or 4 at low SNR, which means the location wanders a lot and makes navigation useless.
If you're locked into as many as ten satellites is there any reason to have erratic GPS performance?
I got a refurbished S3 from Sprint and the GPS is a freaking mess. I can be standing perfectly still and the map starts moving around erratically, sometimes even straight backwards. Other times I'll be driving and it will show me on a totally different street or moving in a totally wrong direction. Sometimes this is going on when I'm locked into as many as ten satellites.
Shouldn't that be enough to get a good fix? Does this suggest that the GPS receiver is working well but there is a software problem? Or is this a hardware problem that can't be fixed?
I reset/downloaded agps data with GPS Status, I've tried TopNTP and I've tightened every visible screw. Nothing has helped. I also can't get a fix indoors like I used to be able to with my original S3.
Any suggestions on other things I can try to make my GPS work or is this a hardware problem that can't be fixed?
This is the fourth or fifth refurbished Android phone I've received from Sprint over the years and not a single one has worked right. It's like they don't ever really address the reported problem. They just factory reset the phone, give it a cosmetic facelift and then ship it back out without any testing.

What Rom are you using ? Did it behave like this before rooting ?

I'm totally stock 4.3, just rooted. I rooted it pretty soon after I got it so I don't remember if it was like this right off the bat. I believe it was.
Weird thing is that today I tried turning of Google location services and that seemed to help a lot. It doesn't seem to be getting a lock while indoors but when I'm driving around I'm not getting the erratic map behavior I had before. No idea if it will work for long, there have been a few other times when I thought I fixed the problem and it came right back.
I know on my previous phone I had Google location services on and it worked like a charm. Anyone have an idea why turning location services off helps and what I can do to make GPS work right with location services off?
Any real downside to keeping location services off?
I've always kept it on. But if your Stock rooted, and have that big an issue with GPS. I would almost be inclined to say it's a hardware issue. You could always Nand, and flash a coherent Rom. Just to see if it resolves the issue.
TEAM MiK MikROMs Since 3/13/11
After driving extensively with Google location services turned off I did not experience any more erratic behavior. Problem solved but I'd like to have location services on.
Tonight I turned location services back on and it still seems to be working fine with no erratic behavior. I haven't given this as thorough of a test but I'm optimistic.
I have no idea why turning location services off fixed things but if anyone comes across this thread looking for a solution to GPS problems try turning Google location services off and see if that helps. It looks to have done the trick for me.
