I'm back in a similar boat on GPS and I'm not able to get any GPS Sats to track at all.
I made a mistake and let the Sprint Customizations run from the Sprint ROM and I know that screwed some items up. I went back and reloaded the VZW ROM to get everything back by letting the VZW customizations run. Verified my Internet, etc and everything was fine.
Then, I reloaded the new radio/kitchen. Everything works flawless from Internet, ActiveSyncing, Bluetooth, etc. Except GPS.
I've got Location On, it's set for COM 4, etc.
I'm almost at a loss as to what's breaking the GPS piece since everything else is working fine. I'm perplexed because I've been using Garmin for a few weeks now without issue (minus the lengthy initial sync period).
Edit 3/12 11:43
- I ended up correcting this by going back and redoing the stock VZW Rom, removing battery, hard reseting and pretty much repeating that process all the way through until I got back to 3.5 Radio, same 3.0.1 DCD Rom and I'm back getting 6-7 satellites from my same window spot. Something had to be screwed up from the Sprint customizations, but all is well now.

Are you testing it outside or inside? I have this exact setup working. It started showing me in the wrong location so I had to move around for a minute or so. Depending on weather, buildings, trees, etc.. it may take a few minutes to lock into enough satellites to narrow down your exact location.
Also, did you use Quick GPS? This speeds up the locking in of the sats.
Yep, Quick GPS. Waited for about 20 minutes near my window. Even on the old rom, it used to take 2-3 minutes to sync up with 7-8 Satellites.

Some have said near a window didn't work for them. Others said it worked in their basement. For good measure I'd go outside away from buildings.
What prog are you using. I think the Holux prog I've seen posted around here or PPCG shows the actual locking in of satellites.
Attached is the tool I use to see what the GPS is doing. It's very simple and reliable.
After checking "start NMEA messages" you should see a log of GPS info being generated.
I also let the Sprint customizations run (although it quit on it's own and rebooted at about 2%). My GPS has been rock solid on dcd 3.0.0.
WI-FI forum as gps starter...
i dont'know if-it was told before but i put some additional packages in the dcd 3.0.0 kitchen like wifi-forum (was curious) and it have a gps fonction tath start the gps...it's not a big deal because it's take about 6X the ram of AstroGPSLauncher that i found the way to run with igo...
But if running WI-Fi-Forum anyway you can by-passer GPS launcher to keeps a little 60 k...

It used to take me under 5 seconds to lock onto a satellite using 3.35 radio, now that I upgraded to the leaked 3.39 radio and DCD 3.1.2 rom it's taking exactly 13seconds to lock onto a satellite.
Does anyone have similar results or is it better for you? please post your times and comments thanks!
well it takes me around 10-12 seconds consistently with 3.39.10, whether indoors or outdoors, in any weather conditions. but, thats the best result i've ever had. 3.35 and 3.37 both took a minute or more to lock for me.

Have you tried something like QuickGPS? I know DCD has a cab for it in the kitchen 3.1.2 thread. It speeds it up a lot.
10-13 SECONDS.... are you kiddin me.... My friend, sometimes I have to wait a minute, so if you have to wait 13 seconds, please consider yourself lucky that your hardware locks on that fast....
i agree, the time you use to open up quickgps or some other program would be longer than waiting the 13 seconds...im happy if i get a lock after a minute or two. sometimes takes closer to 5...
10-15 seconds, I would love that on a consistent basis.
Ok I've been meaning to say something about this ever since the leak from Sprint enabled GPS on our phones...just haven't gotten around to it.
I'm willing to bet a MILLION dollars that I don't have that the gpsone chip in our phones has some sort of built in cache memory that stores the last long and lat coordinates.
It's so weird, EVERY time I flash to a new rom, or even flash the same rom over itself, when I load up Google Maps (brand new Google Maps with all the caches cleared obviously cuz of the flash), IMMEDIATELY the map shifts over to where I was last, THEN it tries to acquire satellites. Once the sats are locked, it updates to where I'm actually at.
I just wonder if there's any way to clear the cache LOL
I flashed the "Leaked" rom,DCD was right,it took about 10 seconds to find and locked for me,same as the 3.35 ROM.
I get a lock in 30 seconds using WiFiFoFum
takes about 10 seconds for me to get a lock...
i couldn't imagine getting a lock in under 5 seconds, and even if i did, getting one in 10 seconds, while being twice the time, isn't much of a real world difference.
i guess it would really matter if you were converting phones into missile guidance systems...
nevermind guys...i was testing it indoors and thats what gave me 13 seconds...im now in my car and googlemaps only takes 5 seconds to lock onto 8+ satellites. yay im happy again

No, there's a GPS chip in there. It looks very quickly sometimes under 10 seconds for me when in a decent coverage area.
I recently used it in an area where I had ZERO Sprint, Alltel, or Verizon coverage. Not a wiff of CDMA for many miles. The GPS worked great and tracked us with no issues.

i think you are misinterpreting his question. he did word it weirdly, but he said, hed be willing to be a million dollars that he doesnt have....
that the chip in his phone, etc...
obviously we have a gps chip in the phone, thats how we get gps coverage....
but ive tried to lock gps with no service, and havent been able to.
is this just bad luck on my part, or is there a way to get a gps lock in airplane mode, or in another country where i wouldnt have service.
thanks

Wow, I thought it was just me that noticed that. Glad someone else did too. I thought it had something to do with a small cache in the GPS chip as well.
BTW Speeds to lock:
3.27 - With DCD (Beta kitchen maybe, I forget) Hardly ever locked so I cant tell you. Got Locks maybe twice a day while trying 30 to 50 times a day.
Changed Moguls at this point due to my puppy eating it. Sorry didint think to grab pics as I had other things on my mind at that point.
3.27 - This was a band new hanset now and I flashed 3.27 and got the exact same results I did the with first handset.
3.35 - With DCD (3.0.1) - Not much better but more consistent locking. Times from 30 seconds (rare) to 5 minutes (average)
3.37 - (DCD 3.0.4) - Fast locks nearly every time, 30 to 60 seconds. First time ever reception indoors. Three sats in my basement office.
3.39 sprint upgrade with a DCD 3.0.4 - INSANELY Fast. After burning the sprint radio I swapped over to a DCD 3.0.4 ROM. You wont beleive this but I made my own OEM for GPS Today. It had 4 satellites even before the phone finished booting the first time! I am not joking! I was amped. Rebooted hard and soft, reloaded differnt roms, tried reverting back to old radio then testing then back again to 3.39. Same results I recieved the first time when I went back to 3.37. Then came back to 3.39 and it was just as fast as ever. This the most solid GPS radio I have ever seen, PERIOD. Faster than any mobile unit I have ever used.
Now what I am about to tell is somewhat of an oddity to me. During my flashng and reflashing of the radio I tried differnt methods. First I flashed back to Sprint 3.35 so I could get the HTC boot screens I liked and then I figured I would flash only the radio via SD. Formmated the card, loaded the ROM, rebooted and the flash went perfect. But this is where it gets odd. With all of the same ROMS noted above I couldn't get a lock at all! I actually had to reflash using the sprint 3.39 leak. I then flashed with a PPC kitchen to get rid of the boot screens this time. Then flashed my best brew of DCD 3.0.4 and this thing is still solid. I even let it sleep overnight, turn it on frist thing in the morning and it gets a lock in under 45 seconds!
(And yes I am sure the flash via SD was succesful)

ActiveSync sinking locks?
I've been using all of the DCD Rom's and have had various levels of locking success, but just ran into something odd - If ActiveSync is running - locks take much much longer, if ever, but if I completely close ActiveSync with task manager - I get locks in seconds. Has anyone else noticed this - and - is it possible to prevent ActiveSync from auto-starting?
I wonder if that is my problem. It takes my a painfully long time to get an initial GPS lock with 3.35 and DCD 3.04. Sometimes it is fairly quick, others it is over 1/2 hour.
However, I have Exchange email push running all the time so ActiveSync is constantly up and doing it's thing.
Quick question, Does QuickGPS need to be running in the background for it to help, or do I just run the update then close it down?
GPS works in Flight Mode!
I recently took a flight from Palm Beach to DC and decided to do a little test while on the plane. I turned on my phone and fired up my garmin mobile XT GPS. The first attempt it locked on to about 10 satelites in under 5 minutes and worked perfectly while in airplane/flight mode. Obviously you can't do this with Google Maps because the maps are downloaded via the data connection, which you don't have at 35000 feet! However it was pretty cool to see the speed of the plane (612 mph) and track my flight path. But to all who were wondering it does work!

I believe it jumps near your location because it knows the coordinates of the cell tower you're connected to.

I don't think you read my post carefully...I said it jumps to where I was LAST...not close to where I am. For instance, say I was in Boston and use the GPS, then I turn it off and go home and reflash a rom. All system settings are erased and all system caches are gone and everything is new. I then go to New York and turn the GPS back on, and it jumps to where I was in Boston before it locks any satellites. I was saying that this leads me to believe there is some sort of cache on the gpsone chip that stores last location coordinates or something.

That's weird. For me whenever i flash and go to Google Maps it always goes either to California (I'm in Mass) or it goes to a blue screen with the flashing blue dot. It's not always reliable which one but it's always one of the 2. Once i get my first fix though then whenever i turn my GPS on it DOES jump to the last position i was in.

No, when I FIRST load Google Maps, it starts up in California, but when I activate the GPS is when it goes to the cached position I was in last, until it locks on to the satellites, then it jumps to where I'm actually at.
There's gotta be a cache.
I am having problems with stability with the GPS in my phone. I am not sure if it is an issue with the phone itself or with the ROM but I'd like to ask for some pointers
I am currently running DCD 3.3.4 with Radio 3.42.50.
I can use the GPS on the phone with no problem for one or two sessions and then the only way to get the GPS to respond is to take the battery out and wait a few seconds then put the battery back in. I have tried a soft reset but that doesn't solve the problem.
Any suggestions?
Thanks
Sounds like you have a rom problem. I recommend to reflash. Because I have no problems with gps on 3.3.4.
i've tested all of DCDs roms quite a bit, and generally have always stuck with 3.2.5 and 3.2.6. im running .6 right now, and my gps locks instantly all the time. you can easily lock up the com port for your gps by letting your phone fall asleep while GPS is running, in an app that requires constant data. soft resetting should fix this. and youll know this has happened if Google Maps displays 'initializing GPS' for more than a couple of seconds. have you applied GCs aGPS fix? if so, have you made the necessary changes with new information? i recently noticed a drop in my GPS locks and discovered i had lost all my gpsone settings in a flash where i lost my akey. when i reapplied the fix, the IP address and port had changed.

4.1.2 could have been great. i wasnt a fan of the unread text message issues, keyboard issues, and i experienced random hard resets. 3.2.6 is the most stable and solid in my opinion.

I agree about 4.1.2 and the text message issue. That was the sole reason I went back to 3.2.6. My GPS is a little screwy though. After going through the full aGPS setup, I can get locks, but it can sometimes take 5 minutes to get a lock, which as you all know, can be frustrating. All it takes is 5 minutes to get lost lol.

Yes the 4.1.2 seems to be having GPS issues for me LOL, I will be downgrading to 3.2.6 myself when I have a some time...
I'll try 3.2.6
I'll have to go and give 3.2.6 a try and see if it works out better for me.
kflipproductions - Is there a program to keep the phone from going to sleep? I have one GPS program (GPSed - very nice) that supposedly keeps the sleep function from taking place when it is logging data but if I run more than one program when it is running then the phone goes to sleep anyways.
Sorry about the delay on my reply - I have been Internet Connection Challenged over the last couple of days.
Thanks to everyone for all the wisdom
I downgraded to 3.2.6 as my GPS was not locking on to anything.
No love... lol
Current config:
MIUI 1.9.16
ROM: ED05
Kernel: Glitch v12 HL (9/22/11)
Glitch 9/22/11 has been a HUGE improvement on my phone's speed, stability and smoothness. However, I'm still getting quite a lag time (3-5 min.) before the Fascinate connects to the satellites when using GPS for navigation.
I'm currently looking at Radio EC09.
Are there any recommendations or thoughts?
Do you leave your GPS on all the time? I've found my GPS takes a lot longer to lock if I was only turning it on When I need it. Now I leave it on all the time and most of the time it locks fairly quickly. Some people have better luck with E05, personally my GPS is better on EC09.
Yes. GPS is always left on. I am constantly using GPS to show specific locations as well as Latitude with family and friends.
My fascinate locks a bit quicker than my wife's with the exact same set up. And hers takes more time than mine to find Satellites. She has gone 10-15 min. without it ever finding a satellite lock.
Sent from my SCH-I500 using XDA App
Updated Radio
Decided to Odin EC09 radio.
First GPS lock was nearly instantainiously; however, following uses were not as quick. I'll test it out today and report my findings.
I have tried just about every GPS fix/tweak out there. It seems like everything works well once or twice. Maybe the placebo effect. After a day or two it is always back to the random lock times of seconds to minutes. I have had the best overall luck with the PWGB rom. 9 out of ten times it locks in under a minute which seems to be the best my phone will do.

thats because things get out of wack like the compass or need to be updated like agps data. if youve tried the GPS fixes out there like downloading the gps.conf file from powerwash/geewiz and deleting gps files in miui (not sure about others) then always check out the compass/agps if you arent getting a quick lock.
I usually use GPS status to check it and it downloads AGPS data. I've heard the compass can be a problem but I have seen my phone GPS lock in a few seconds with the compass reading WAY off and I have also seen it take several minutes when the compass is perfect. Seems to be no pattern on my phone.
I have been on EH09 since it came out. Now on PWGB latest version it has consistenly locked quickly since flashing.
I posted a while back with this problem but still with days of searching I haven't found anything to work.
Its my GPS I can't get it to work.
I've wiped several times
Reinstalled several roms
Reverted to stock and upgraded to e5
Tore i777 apart and inspected and cleaned hardware
All seems fine
No damages
All else seems to work just not gps.
Also my signal bars regardless of wifi or network, are
Always grey.
Has anyone else had this issue? My GPS used to work prior to rooting it was accurate to 5m and locked fast but now I can't get any sats in view or even GPS icon in the status bar.
Leaving me to assume my GPS died after 5 months of owning.
Which I hope I'm wrong cuz this phone kicks arse and spanked my sis icrap 4s

Didn't show up in gb kk6 either.
Does this point to hardware fluke?
I've flashed an arse load of kernels, roms, and modems yet can't seem to get any GPS activity
Only maps network loc of 2700 accuracy or wifi lock.
Thank u both for replys
By chance did you have an otterbox on the phone and drop a couple times (mine saw a brick wall on accident it decided it didn't like the convo I was having and launched itself into the wall)? Thats how my GPS died and I took it in and got it replaced.

Has anyone else experience very slow GPS fixes if "Device only" mode is enable (for example because you don't want your data leaked to Google by enabling "High accuracy")? I thought this phone was supposed to support GLONASS, in addition to GPS.
I've always used GPS alone on my old Nexus One, and today I ran a test, with both devices freshly rebooted and in the same location. The N1 took 28 seconds to get a fix. The Xperia Z2 took 2 minutes and 16 seconds. This is with the latest firmware, .402. (With the previous one, FW:17.1.A.2.55, GPS worked a little faster, but still took about a minute or so, in plain outdoors with no trees or tall buildings around).
I'm having the same problem too using Strava. Can't get a fix at all

Based on my experience this is due to gps configuration file: fix that and signal get fixed much more fast and position gets more accurate... Before editing that file you need root and you should know what you are doing, because messing up with its content can bring longer time to fix and less accurate position. A better explanation is long and technical, so I kindly invite you to search more on this topic, if you're interested in
