Just curious if anyone else has issues with GPS reception on their sprint touch. I upgraded to the latest htc rom earlier in the week and everything is great except I cannot get GPS to hook up - I've had it work only once.
i upgraded too and i'm using GPS with GoPilot Live, iGO8 and Garmin Mobile XT and it works without issue.
what GPS program are you using with your touch?
Google maps is the only application i've tried. It will search (and search, and search) but doesn't find any or only 1 sat.
Make sure all your settings are correct and try using something like GPS Viewer to get the initilal lock.
Any hint on which settings, and what the the correct values for those settings would be?
Thanks for the tip on GPS Viewer - I will def check it out!
Thanks,
Tim
First, make sure you have the proper Radio/ROM, I assume you do.
Second, under System Settings>External GPS
Programs>COM4 Port
Hardware>(None) Baud Rate>4800
Access>Check Manage Automatically
Third, under Personal Settings>Phone
Services>Location Setting>Location On
Fourth, the Registry
I know of only one value that may help if you change, there are more, but haven't seen them, and I believe it's different on some carriers, like Sprint
HKCU>Software>HTC>SUPL AGPS>GPS Mode
For the inital sat lock, make sure you stand outside on a clear sky and wait at least 5 min, if it takes that long.
The first time I did this, I was trying from inside, finally tried it outside after 3 days of no luck, but now it works quite well. I usually get connected under 30 seconds. As long as your in the same area when you reconnect it should be quick, the first is usually the longest. And I personally use LiveSearch for the directions.
Change from 2 to either 4 or 1, this may help, never really guarenteed though
I was in Boston this weekend and noticed the GPS on my Touch would not lock in a signal in the financial district surrounded by tall buildings. But when I have a clearer view of the sky it works fine. Are you in an open area when you are using it?

It surely helps! Any obstructions will make it harder to pickup the signal.

I was having problems with mine too until I did the 4th one and changed it to a 1 from 2 and it works much better. Try it and see you can always turn it back to 2
This helped me

My apologies if this has already been posted somewhere. I did a search and came up empty...
So like a lot of people, I've been having some major problems with the GPS's reliability on the Touch (yep, last week's flavor of the week). It connects only when it feels like it, and numerous resets seem to temporarily solve the problem. Well, changing the following registry value seemed to solve all of my problems:
[HKEY_LOCAL_MACHINE\Comm\ConnMgr\Providers\{7C4B7A3 8-5FF7-4bc1-80F6-5DA7870BB1AA}\Connections\Phone as Modem]
"Enabled"=dword:00000000"
Change the value to 0, and soft reset.
It appears that the GPS, by default, makes use of the "Phone as Modem" data connection to take advantage of aGPS, but if a "Sprint PCS" data connection is already active, the GPS doesn't swap connection methods and ultimately hangs. This problem is exacerbated if you have Push services or other data connections running.
I personally haven't noticed any problems with disabling PAM, but as usual, your mileage will vary. For me, I get GPS locks within 15 seconds when I'm in a reasonably accessible location, and I no longer have to reset-and-pray to get this thing working.

Link not working, repost.
hate to tell you this, but if you are using the builtin GPS, a clear view of the sky does nothing to improve your gps position locking. our phones have AGPS which means it is fake GPS. It uses the distance from cell towers to triangulate your position, not satellites. Thats why you can get a lock inside with no view of the sky.
some ROMs have different settings on them so following the above directions should work. Or you can do like me and find a better ROM

Hello!
I'm just back from a trip from london. I brought with me my P4000 thinking that I would be able to use it's great GPS abroad.
It never worked once.
I thought this thing had an aGPS chip, meaning it was a true GPS that could be assisted by cell towers to find a fix faster. So, my understanding was that it should have worked abroad, albeit slower to find a fix then here.
As soon as I got back home, it started working again.
Any ideas?
Mod Edit: Moved from Titan Upgrading

If you were roaming overseas, then you won't be inside Verizon's firewall, therefore you won't have connectivity to the PDE server. The standalone GPS should have still worked, though it probably would take a lot longer to fix due to the fact you moved a great deal since the last fix. Did you try to use QuickGPS to download the ephemeris data? That probably would have sped up your fix a little.
I'm using tomtom, so, I don't need access to verizon. Anyway, I'm with Telus.
I've let it stand by the window for hours and it never got a lock. I didn't try QuickGPS.
Should I have switched something in the registry to have it work in standalone mode instead of assisted?
Well, i'm living in Republic Of Moldova. WE have no aGPS here at all, but i still can use GPS function on Titan. I have to wait about 1-3 minutes for lock.
I have installed DCD 3.2.6 rom and 3.42.50 Radio. Use SeaSGEE to download ephemeris data and Navitel Navigator. But Tom Tom and any other programs work fine too.
PS Sorry for my English.
I recall having a similar discussion in an earlier thread.
See if any of this info helps:
http://forum.xda-developers.com/showthread.php?p=2538917
If you do that right, i'm pretty sure it won't even attempt to connect to a PDE server (when u change GPSMode), so you should be able to get a *slightly* quicker lock, as it won't waste time looking for that server.
I do also suggest using some other tool like QuickGPS to retrieve the ephemeris data before trying to get a lock; it *should* speed it up, but I don't know how true that really holds.
Ok,
Thanks for all the infos. I'm going to Madrid next month, I'll try again there.
I was able to get GPS locks all over Europe no problem this past July.

Well it doesn't matter whether you have Verizon or Telus when it comes to aGPS. I was referring to aGPS. If you aren't inside your carriers internal network, then you won't access the PDE.
The GPS should still work regardless, just in standalone mode, which is why I asked if you tried QuickGPS to try and speed up the lock times.
I was under the impression that there is a registry setting for the global "zone" for our GPSr to look for and that it was set to US.
From the posts I reviewed few if any folks have been able to lock overseas unless they got locks while traveling
GC, have you found any settings in the registry for this?
In QuickGPS I think the setting is as follows:
[HKLM] - Software\HTC\QuickGPS\region
Its set for US for me here in TN and I think someone from Holland posted on PPCGeeks a long time ago NL worked for him to get a lock once he found and got it via trial and error...
I am sure you are onto something here
I think you guys are really onto something here. I have had the most frustrating time with my titan because of this very issue. I travel outside of the USA frequently and in all my travels have only managed to get a lock once! All through Australia and Thailand with no phone signal I was unable to get a lock with either flight mode on or phone mode on. Even in Taiwan where VZW has some modicum of representation (i.e the phone function worked but zero data) I go no lock.
gc was right about the agps thing. Outside of Verizon network you will not get assisted gps (although strangely when in "extended area" roaming inside USA it still seems to work).
in the end i tried a hundred things to get a lock including leaving the phone out in the full view of the sky for 6 hours. Nothing worked except the gps mode that scrawnyb talked about. I finally got a (very slow) lock after what seemed like hours.
I really believe that osteo's answer about the zone (i.e. "US" here in USA) is also part of the answer. I can only assume that the ephemeris data has to be relative to where you are on the earths surface, so the phone having some idea of where you are surely would help (especially without cell tower help from agps).
Targitai, if you visit this thread again can you please check the setting in your phone to see what zone setting you have that assists with locking. You need to look in [HKLM] - Software\HTC\QuickGPS\region and check that you are not set to "US" or similar.
I wont be traveling OS for a few months now, so I cannot confirm any of the above. I hope others who are traveling see this thread and can report back.
Thanks for the helpful info on this thread. This problem has been bugging me for months. Strange this is that my bluetooth gps never takes more than about 2-3 minutes to get a lock, even after crossing to the other side of the earth, over 9000 miles to Australia.
Well,
I'm here in Madrid now and it doesn'T work.
I tried changing the registry key of the GPS mode and it didn't help.
Any other things I can try?

How long did you wait, and do you have a clear view of the sky?
After traveling a long distance it can take some time to download the full catalog info on the satellites.
I waited a few hours in clear sight of the sky.

I have had my gps lock over the ocean in an airplane. I dont have navigation software installed other than google maps so I just used Visual GPS to verify I had lat/lon fix and a gps speedometer app to tell me I was going at the same speed the captain had said. No wireless data connection at all.
Hi, I have a similar problem, but when I'm in a no service area, the GPS locks in 2 minutes. When the phone gets a cell phone tower, never gets a lock unless I let him overnight catching sats. I'm from Venezuela, may be the cell phone towers or the network, I don't know, induce some kind of conflict in the position calculation of the GPS. In the flight mode the problem persist.

Most PDA GPS's do not turn on automatically by themselves unless instructed or invoked by a software application. I have not looked carefully at my Jade clone's SIRF's specifications but most GPS under ideal situations can take as little as 42 seconds when warmed up to get four satellites to lock on to. Four satellites are necessary in most sytems are necessary for 3D satellite navigation (satnav or GPS).
What are ideal situations? Glad you asked. Basically, one of the most critical needs for a GPS is accurate time. This is the first item that must be sync'ed by satellites. To use a gross example, let's say your clock is off 60 minutes. In a car that could equate to roughly 60 miles. Satellites need accurate time because when they begin to sync, they will compute what satellites are available to sync with your GPS. Just like the sun, moon and stars are only in the sky at moving intervals of time, only a fixed amount of satellites are overhead at any given time.
Once your GPS begins to sync, ephemeris data (which satellites and the times they are overhead) is transmitted to your GPS. When combined with accurate time, the resolution of where your receiving GPS becomes easier.
The next critical issue is where does your GPS think it is. If the GPS was last turned on at the factory (testing), then it will store that location as its last known position. Guess what? If you're in Paris, France and your GPS was made in Malaysia, your last known position known now as initial positon to the satellites will tell them based upon time to use satellites in the Asian area to compute your satnav position. A GPS without a good initial position will make it difficult for satellites to accurately determine your location which could now takes a minimum of four minutes as long as ten minutes and maybe even hours.
Finally, where is your GPS physically located? In ideal conditions, it is outside with clear sky overhead in a stationary location. It's easier to shoot a sitting duck; a moving target or a GPS on the go complicates all the issues of time, location and signal acquisiton.
To help you, I recommend you download a small cab file that be used in your Today screen. It is aptly called "GPS Toggle". In essence, like a mechanic warming up your car prior to you driving it on a cold day, this plug-in "warms up" your GPS for you prior to needing it.
There is one thing you need to do to help your GPS - it is best for WM to manage it (a recommended feature from Microsoft). Go to the Settings tab, External GPS (why it is called that on my Settings tab is beyond me). Then click through the screens to have WM manage the GPS. On one tab you will asked to choose a Port from which all your programs will access data. You need to use an unused Port. I recommend Port 9 but that is up to you.
The reason for doing this is if WM manages the data, it will keep the GPS on and provide the resolved info to all applications. If the programs managed the GPS, they could selectively turn on and off the GPS and also block each other from using the GPS. You don't want that to happen. That is why MS recommends WM manage the data.
GPS toggle, when installed on your Today screen, will have an ON/OFF switch. When you turn it on, it will on the same line tell you how many satellites it has found and when it has sync'ed with them. When you see that four satellites are in the green (meaning your GPS is found ready for 3D satnav), then you can use satnav program of your choice.
The GPS uses battery power and supposedly is a big drain on smartphones. You want to turn it off and on only as necessary. Hope this helps (it's sticky stuff good info)!

Cloned HTC Touch 3G
I went through the posts - I guess even I have landed up with a cloned HTC Touch 3G. Wonder what the drawbacks are. Somehow after a lot of tinkering I have been able to get my GPS to work (yes it has a built in GPS antenna) and it's accurate!
I set the hardware to COM 3, baud rate 4800
application to COM 0
In Google maps>options>GPS settings>manual settings (COM0 baud rate 4800)
IT WORKED!!
The WiFi can't be turned on with TouchFlo. Anybody has a solution to that?
I can't get a satellite lock on my HTC Snap.
I have enable "use GPS" in google maps. google maps will search for satellites and after sometime come back saying weak signal & some recomendations to look for clear view of the sky.
Garmin XT also can't search GPS satellites. I install GPS Test, it seems that there's a GPS hardware but somehow the signal reception is super weak.
I have sent my Snaps to HTC service center and the best thing they can do is change the mainboard. This also show no result.
Anybody, please help. i'm starting to get frustrated with this GPS issue...
Bing GPS
I use the Bing app and have similar issues establishing GPS signal. This is my first GPS device so I'm not sure if this is normal, or if the phone is crap for GPS, or if I'm doing it wrong. I try to keep the QuickGPS updated, but that doesn't seem to help. I thought AGPS was supposed to be fast, but faster compared to what? Maybe this is 'fast' for GPS. I have seen friend's full on GPS devices and they seem to pickup pretty quick. So... who knows?
One thing to definitely try is make sure quickgps is up to date and automatically downloading. garmin could NOT find my location without that up to date and it would show one red bar signal strength. once i loaded up quickgps, updated it, and ran garmin again, full green signal.
It's The GPS Hardware ...
I've tried it all with my Dash 3G -- and concluded that it's the GPS in the phone that is garbage. I've since switched back to my trusty OnCourse Bluetooth GPS and I get a lock in Google Maps in less than 30 seconds and in Garmin XT in less than 10. IMHO, the GPS is certainly a weakness on this phone.
It finally sunk in for me when I lost signal 9 times while walking a few miles down Beacon Street in Boston. Holding the phone in my hand it kept dropping the signal over and over again. So I gave up. Built in GPS is handy in a pinch (when you have 30 minutes to wait for it to find a signal) but for serious navigating I use my Bluetooth GPS exclusively now.

I completely agree. Simply because something is not working like it should for these others does not mean that the GPS is not good. I use garmin xt with my ozone and its is extremely fast at updating my position as i'm driving along.
Problem solved
Let say that i'm in a really bad luck. this is my first GPS device and its not working. After the 2nd time come out from the service center (2nd concecutive mainboard), then the GPS is functioning, normaly....
my maple can get lock on GPS signal quite fast. with AGPS updated, it can get signal lock within seconds (given you have a clear sky view). i found that it could takes some time for Garmin XT to get GPS signal, so I use GPS Test to speed up the process then start the Garmin XT.
so for those who can't get GPS signal. it's definitely your hardware. I also found that the online customer service officer at HTC is just a mere lips service / useless. they keep telling me to be patient and patient without real action.
There's a free GPS testing tool for Windows Mobile called GPS Test. Once that set up, you can find out which serial port is used by the GPS receiver in your Windows Mobile, and set Google Maps GPS setting accordingly. Once it's set up, Google Maps can easily find multiple satellites if you're on open space. Once it's using GPS, your location on Google Maps will be a pin point, rather than a large circle denoting your approximate location.
PS: Found out with GPS Test that my GPS receiver in my Snap is using COM4 port at 9600 bps
Sincerely,
Paul Pambudi
WIND Mobile HTC Maple users not getting GPS working PLEASE READ!
I went through four HTC Maples (two accounts each 1st phone was a warranty exchange for another non-related problem). Each of the four Maples could not lock in single GPS satellite. WIND tech support had no clue after many calls and tests run at their tech support offices in Toronto. WIND recommended that I get in contact with HTC directly to see if they might have a solution.
One call to HTC started the ball rolling and setup a trouble ticket. Within 3 days and about seven call backs to trouble shoot, HTC had the solution and both of our Maples now have fully functioning GPS with Google Maps.
The problem was in the ROMs that had an old version of Google Maps (both their WM 6.1 and WM 6.5 HTC Maple ROM for WIND accounts).
Solution: using the Maple's browser go to m.google.com/maps and install the latest version. Problem solved!
HTC customer service in North America ROCKS!!!!!!!!!!
Will I buy another HTC product? HELL YA!!!

My Snap used to take 30-40 seconds on a cold start to get a location lock (with aGPS turned on).

Thanks for updating the link.
I have tried both of the CABs for the non Nokia and both make no difference if you
can't get a GPS lock. AGPS simply does not work using the latest Google maps CAB
available.
The "FF Ultimate aGPS Tweak_supl.google_Generic.cab" actually makes Google Maps
take forever to just start up after being installed and still no location is updated
indoors. Also, the phone will not snyc now with the desktop and this is after three
soft resets.
Even worse is the fact the phone now runs slow as hell. Everything takes forever
to open and is VERY sluggish.
Installed the other CAB "FF Google aGPS Settings Generic.cab" and still the same
problems. What could be the problem?
Finally got fed up with the POS CAB and uninstalled it. So far I've notice that the
phone has recovered its speed opening items and the right ones not like before
with that POS CAB which would cause all kinds of problems. Snyc now works
and so this looks like I'm back in business minus the fact I still can't get the aGPS
to work.
Oh well, you can't win them all...

Why is the Focus' gps so slow? I don't know what's wrong with my focus, I mean it just takes so long to get the coordinates of my location. I even have to go to a open sky area then wait for few minutes before it can successfully get my coordinates. Its just so annoying, this is a post ipad product, how come an ipad 1 can get my coordinates even inside the room without any difficulty?
Is this a hardware issue or just a firmware fix is due?
my focus gets a very quick lock about 90% of the time, every so often it will take a mintute or so to lock, but i've had this happen with pretty much every phone i've owned, so it seems about average to good for me...
the ipad1 (unless a 3g + wifi model) uses your network to locate you, which is why it's quite fast.
We have 2 Focuses, one AT&T and one Rogers. With both I get about the same time to get a fix, and that's slightly under a minute, in my location (several tall buildings near).
With what app do you check your GPS? I recommend GPS App
It's an AT&T. My ipad is a 3G+Wifi. It gets gps coordinates via gps chip and not A-gps. Most of the time the ipad gets coordinates very fast in span of 20-25 seconds, boom you know where you are in the map.
I am using the built in MAPS software to track my location. Does the software matters? I mean if the chip is really weak, what can the software do ?

Sometimes it does. To give you an example why: GPS without efemerides take several minutes to get a fix. GPS with efemerides take 20s to 1 min to get a fix. Efemerides are downloaded via software.
As for the app I found it to be good enough for testing the GPS part.
I can agree with you. Sometimes while driving if I take a different route than the one the phone provided for me, it will either fail to locate where I am for a few minutes or just fail completely.
I think it's time for a small update.
Is it just a minor driver issue? I hope so , otherwise, we have to live with it or change to another device.

Again, other people (including me) haven't experienced any issues.
In fact, it works great for me with Turn by Turn Navigation, even inside the car on the passenger seat (not near the windshield).
Try changing some GPS settings in the focus diagnosis app
Sent from my SGH-i917 using XDA Windows Phone 7 App
what are the settings in GPS I have to adjust to make it perform beyond expectations? Which specific diagnostic option I have to tweak?
Did the OP ever find a solution to this? I'm having some slow locks and the occasional non lock.
I know in the diagnostic app you can get to the GPS with*#1575# but I'm unsure of what data can possibly be changed.
I'm having the same issue on my Focus (Rogers). It never connects to sattelite and always uses aGPS. It's very annoying. I tried many different gps apps and get the same behavior - very innacurate. Garmin allways says "Can't connect to sattelite", gMaps always shows cell tower icon. My phone is unlocked using original Chevron method (not Chevron labs). I also tired to change settings in *#1575# and turn ON/OFF TLS and GLONASS but nothing helps. Should I try hard reset?

I did a hard reset last night and it seems to have cleared up. I also installed this app, have to click the link in the post, searching for it didnt work.http://www.wpcentral.com/new-samsung-high-fidelity-position-enhances-gps-modifies-settings
Not sure if it's a placebo or not, but it seems to be working better.
is Focus GPS native chip or just a-gps?

Assisted GPS, which includes standard GPS in Standalone mode, so it's better than any native GPS.
after my hard reset the GPS locked much quicker for about a week, then it started acting up again.
my new solution seems to be much easier than a hard reset. Just briefly switch to airplane mode then re-enable your data and open maps up again. Been working great for me.
Faster solution that's been working for me. Turn on and off location services. My phone never locks without this, which is sorely annoying.
I had this problem on 7392 rom. After updating to mango 7720 and 8107, I get fix in 3 to 7 seconds in my room Tested with gpsinfo, it's real satellite data, not agps. I have also installed high fidelity position settings app. Don't know if it's helping.

Seems to have GPS lock problems after kk update. Very difficult to get lock, and even when lock is eventually found, signal drops off easily. Anyone with this problem and have a solution for this?

To be honest I have seen that on my 4.3, where GPS lock takes more than twice longer (sometimes 5-10 times) than on my S3 - there is another thread on that somewhere. I was hoping 4.4 to come with improved firmware on that one, but apparently not so much
i'm not on kitkat, but i have problems with gps.
however, problems occurs only when recording a track with "my tracks" from google.. as navigation apps works fine, no issue with the signal. only my tracks is giving me huge gaps between checkpoints..
I dont have gps locking problem in kitkat, but with directions while navigation, gps marker points in opposite direction.

I have actually had the same problem, I thought it was only me. I ran stock Italy ROM 4.3, but don't see any improvement under 4.4.2 Poland. Even GPS Status app does not seem to help.

Interesting, my GPS lock in MapsWithMe Pro is almost instantaneous. About 5 seconds, usually. Unless I'm indoors, but you can't blame a phone for the laws of physics.
N9005 DBT 4.3 MK2/MJ7/MK2
If I use Google Maps, it will only triangulate if I turn on 'Use WiFi', 'Allow Google Location' and more of that rubbish, and even then it takes about 5 minutes to get a lock.
My advice: Stop using Google Maps.

1. I almost NEVER use Google Maps (OK, maybe for testing stuff) - and I can only wonder how you got that idea anyway Generally I am very happy with Sygic and I also use GPS Test for quick testing, also Accurate Compass (for very quickly calibrating the compass).
2. I have now tested MapsWithMe for like 2 days and I can guarantee you that the "instantaneous GPS lock" is COMPLETE bullsh*t - the program is only caching your last position (which generates huge problems if you move between locks), then it tries to use location data from your WiFi connection if that is active; if not it then tries to use some very basic and EXTREMELY INACCURATE positioning based on GSM cell towers (at which point the error displayed for my position was in the order of 1-2 km); during all those steps the program also fires-up the GPS - but it acquires the lock EXACTLY with the same speed (or complete lack thereof) as any other program attempting GPS lock
3. What still remains a little surprising for me is that sometimes (like well over 50% of time but NOT 100%) my GPS lock is MUCH, MUCH faster (in any program) if I have the Mobile Data connection active (which normally I rarely have); once I have the GPS lock I can then stop the Mobile Data connection and the lock remains perfectly good. EDIT: However the WiFi connection does NOT seem to make ANY difference on GPS lock whatsoever.
Isn't this basicly what AGPS should be doing. It requires a data connection to get the positioning fix faster than just using the GPS. once it gets the location it does not need the data that much. Except for google maps to download the map and navigation information, and this is why it needs a data connection all the time.
Sygic does not need a data connection for the map nor navigation. But, of course, having a data connection well get the fix faster.

Oh, I had no surprise from the fact that aGPS can work
What I might have not mentioned above (fixed that now) was:
- a WiFi connection never improves things
- my old i9300 never needed the mobile data connection (or any kind of connection - that made basically no difference on it).
Those two seem to suggest that the Note3 "GPS driver stack" is worse than the old i9300. Also the fact that the mobile data connection does not improve things in 100% of the cases was IMHO interesting to note.

Ah, miscommunication. I did not mean you used Gmaps, I meant people in general. Gmaps is a nightmare, on 50Mbps LTE it still barely loads... Even on my homenetwork of 120Mbps WiFi it takes ages to load the map itself, surely the packages are not 1GB a piece?

I travel an average of 600KM a day.
Yes, MWM caches the last position. Which is hilarious from time to time, last week it thought I was still in Zurich when I was actually in Berlin. If you click the gps icon three times again, it repositions. Waiting for it to refix automatically takes ages.
I do not have WiFi on the Autobahn, (If only! ) and 70% of the journey I do not even have a mobile signal.

Nothing suprising about that. It uses the celltowers to triangulate by sending a data package, as opposed to attempting to connect to three satelites. If the network is fast enough (UMTS and above) it is much easier to get an accurate position. GPRS doesn't work all that well, nor does having 1 bar of signal on anything but LTE.
WiFi only helps if there are active points nearby (no need to connect to them, detecting them is sufficient) and you have 'use wireless networks' enabled under Location Settings.
I just tested: WiFi and Mobile Data off, No network signal, on the Fyra (Highspeed train. Or as much as the NS can manage, anyway.) from Schiphol Airport to Breda @160kph. Got a lock with SpeedView in 15 seconds, detected 24 sats. Not instantaneous, but then you can't ask for that at such speeds.
I do have to say, on the previous firmware it took much, much longer. About 1-2 minutes. And I tried a Dutch Note 3 yesterday, it required almosylt a minute on the same firnware version.
The weather also influences the signal, clear skies vastly improve things. As does solar activity. Last October you could wait an hour and not get a lock, due to a solarstorm causing too much magnetic interference in the atmosphere. Even my GPS locator itself took almost half an hour.

Actually original aGPS doesn't quite work that way at all - here is some info from some of the guys doing some of the Linux kernel drivers for aGPS devices (I can not guarantee it is 100% accurate but fits OK with other info that I have seen):
http://wiki.openmoko.org/wiki/Hardware:AGPS
And another thing to remember when testing GPS - after a successful GPS lock it is very likely that you will have a MUCH faster 2nd GPS lock for up to about 2 hours. So any such immediate 2nd lock should be see in the above context, also the lack of it
Least this problem isn't just me. Always used to track my rides with Endomondo without a hitch but I went out for the first time since KitKat and I couldn't tell you how many times it dropped out on that 2 hour ride ... but it was alot

Seems to be a very common problem. Read somewhere that this is a software issue and there is a fix if the phone is rooted by flashing a patch on it. But I'm not about to root my phone and lose the warranty. SAMSUNG please release an update quickly that fixes this problem.

I am rooted (with knox 0x0 ) and I have looked into that patch - the one that I saw only sets a different AGPS server address and has minimal or no impact - actually I have a strong feeling that there is something in the CSC that overrides it, which explains why the AGPS server only improves things for me when connected only on mobile data and not over wifi.
IMHO that seems to be mostly a firmware / software driver issue - on my old S3 it looked like there was a lot more "caching" of the "GPS almanac" and slightly more pre-calculation of the "GPS ephemeris", possibly on the application CPU on the phone (which has humongous general-computing power compared with the CPU used inside the GPS circuit, which however is highly more specialized). On the Note 3 it seems to work in a "safer" approach in which older (than like 2 hours) GPS almanac data is considered inaccurate and so is the time otherwise used to pre-calculate GPS ephemeris (which time to be honest I have seen WILDLY inaccurate on some carriers, something like 27 seconds away; and of course if the time is not carrier-set the phone time can easily be tens of minutes away ).
