the GPS is not accurate at all! - AT&T Samsung Galaxy Note I717

Yes it locks on instantly and to a lot of satellites, but from there it goes to hell. I just completed my first run using this phone. The route i take is 5.5 miles but the phone said i only did 5.0. The app i use is called MyTracks and it overlays your path with Google maps. Normally with my old phone it lines up nearly perfectly, showing my path as being on the sidewalk. Well with the note it shows my path as running through front yards and houses, which of course i didn't do. All of that cutting through yards and houses is why my path appears to be half a mile less.
Fyi it is a sunny clear sky so no issues that way.
Has anyone else taken their Note running and experienced similar or opposite issues?

Using Navigon on both S2 and Note. Very accurate except my maps a bit old. So it shows to one way street sometimes. The Note lock within 3 seconds. Don't have your issue

I've taken my note in my car, and I can tell you that I've never seen a smartphone's GPS perform as well as the Note does. I get a lock in 5 seconds or less, and I've seen as many as 25 satellite locks, with a position as accurate as 5 feet for a long duration.
Do you keep your Note in your pocket while you're running, or is it exposed/attached to your body somewhere?

MyTracks and Navigon differ in that Navigon locks to streets, eliminating spurious off-path tracks while MyTracks saves every position report if you have it set to do so.
I used to use MyTracks to diagnose GPS issues w/captivate etc.
So far, I haven't seen any of those issues with the GPS in this phone, however, it is always spot on for me. Actually the best GPS i've used in a phone yet.
I am leaning more towards a faulty unit than a design issue..

The note is in my pocket at all times. I did The same with my old phone. The issue could be that, or maybe it just can't track slow speeds very well but it works fine at higher speeds like when driving. I am going to take it in the car later and drive that same path with it exposed and then again with it in my pocket and see what happens.

Maybe i need to change a setting in MyTracks since this gps is supposedly so accurate? I use all the default settings other than setting an audible alert for every 5 minutes.

No problems with GPS at all here. I've had 10+ satellites locked on inside a building with lots of glass. It was able to pinpoint my exact location within the building.

I'm getting absolutely amazing GPS performance here gets a lock almost instantly and is very accurate. Maybe try turning off mobile networks and just using the satellites. I did that and still get a lock just as fast and is far more accurate at least for me.

worked beautifully for me today in the car

Have you changed any settings in mytracks or do you use the defaults? Is your phone in your pocket or out in your hand?

I did turn off wiring before my run, maybe there's a bug when you do that?

Just got mine yesterday. I had a Galaxy Tablet, used it with WAZE for navigation of sorts. The SGT would always show me not on the exit ramp at a particular exit, difference distance was 100 feet.
The Note shows me on the exit ramp every time, it is much better GPS

So driving down the road with the Note in my vent-attached phone holder, the GPS works flawlessly. When I put it in my pocket, it started getting inaccurate again. I'm not sure why this is the case since my old phone worked in my pocket just fine. I am hesitant to carry the phone in my hands for the 5-6 miles I run, in fear of dropping it. If others report that MyTracks works flawlessly with the Note in their pocket, I may return mine and try another.

18 sat LOCKS indoors. 3m accuracy instantly.
Best GPS performance out of any phone.
I think it's just your app.

I have Runkeeper Pro and Edmondo so I'm going to try one of those next time. I don't like those apps as much because they don't let me see a granular breakdown of my speed throughout the run. Meaning, I can see a chart of exactly how fast I was running all throughout my run. With these other 2 apps it just shows you a total speed at the end of the run, Maybe I can find another app that does what I want.

I use my GPS quite often and I will say there is absolutely NOTHING wrong with this GPS. Best phone GPS I have ever had.

I've narrowed down the issue to it only occurring while in my pocket. I am going to try some other apps or buy an armholder.

How is ATRIX GPS? Can someone do a review for us?
It works very well, smooth & very accurate. I haven't experienced any issues with it.
Its much better than the captivate. I used Google Navigation to go somewhere the other day and it stayed locked pretty much the entire drive. It took a couple of minutes to get an exact lock (not that that was an issue) but after that it was pretty smooth.

GPS on Captivate was a joke, it never worked for me.
It seems really accurate and fast. Google Maps/Navigation is smoother than ever on the Atrix. I received my Vehicle Dock yesterday and it's great. If you aren't using navigation the car home app shows your location on the map and the direction and even the speed you are traveling really accurately. Overall it seems even more reliable than either of my former phones the Dell Streak and Nexus One.
Extremely good. I get a 9ft lock, indoors, instantly.
Coming from a Captivate, I am extremely impressed. It seems to lock even faster than my old iPhone 3GS. Needless to say, when going from the iPhone to the Captivate, I was very disappointed in the GPS.
Best GPS I've seen on a phone, ever.
I was pretty happy with the GPS on my G1, but I LOVE the GPS on this. Very fast acquisition times, even in hotels and parking structures.
I've used it a good amount and it's been flawless. I use it with the Atrix car dock. I've used it for nav while streaming Pandoro through bt in the car and had zero issues with it. Mapping is quick and accurate. I can't say enough good things about the Atrix/car dock combination.
tks guys... I'm coming from a Galaxy S, actually I'm suing Samsung Brazil. They didn't want to exchange to a new phone or give my money back cause technical assistance (don't know if you guys call companies that fix defective stuffs) said my GPS was ok. I heard "hey look, you got 1 satellite fixed... it's not a GPS issue"... damn it...
I wish in Brazil companies respect us like in USA.

That sounds more like scary lol
very quick compated to my old captivate
It was wonderful for me when I tested it at the AT&T store. It nearly immediately had a lock even being inside the store.
Had a Captivate, and the major reason it went back was the poor GPS. Outdoors with a clear sky view it showed 30-35db signal readings, a full 10-20db less than an obsolete (two generations back) Deluo Earthmate usb "puck" gps sitting right next to it.
The Earthmate and a Nuvi both had signal and position, the Samsung kept saying the signals were too weak to use.
Switch to the Atrix: Outdoors, position within 10 feet (so it says) just like any commodity-grade GPS these days.
INDOORS, in a room with a steel shutter over the windows, it showed 30-35db signal strengths, equal or better to what the Cappy showed OUTDOORS with a full sky view.
No question in my mind, the Atrix has a commodity-grade GPS that works perfectly well. Whether they've done any tweaks or cheats in how it works, I don't know. I find the accuracy reading surprising, since that's pushing what a WAAS-enabled GPS would get and AFAIK no cell phones use WAAS GPS.
Checked position on Google Maps, and it is right on. I'm a HAPPY CAMPER and I'm not an easy customer to please.
Also, when the battery is fully charged on the Atrix? It doesn't wake up and ring and complain it needs to be unplugged. The Cappy tried to wake me up every night. Bad Cappy!
Now, if they'd only enable the FM radio...

Just came back from a 3.5 hour trip, one way, round trip (left last night and came back tonight), and the phone "lost" me twice - once was a typical SGS-style issue where it kicked me off the highway I was on and said I had to get back on at the upcoming exit, and the second time, for no reason whatsoever, the GPS kinda turned off.... I say "kinda" because it was still on when I checked my GPS widget but the GPS icon was gone from the notification bar. It wasn't searching for GPS, it just stopped showing up there. I turned it off and then back on, found me again in under 3 seconds.
Those were the ONLY issues I had in 7 hours of using the GPS during the last 24 hours. Tell me that isn't the best data you've ever heard on a cell phone's GPS unit???

If by accurate you mean reading you as 3 streets over...
not sure
I use mine with a running app Runkeeper. It was very good the first 2 times I used it showing 3.08 miles for a actual 3.1 mile distance. But yesterday is showed 5.37 miles for the same 3.1 route.
I hope it was just a glitch which happens depending on clouds but yesterday was clear.
meh
Meh, it gets poor signal indoors. Outdoors, it's often off. To truly test the GPS, you need to disable WIFI, otherwise it will use the BSSID's of nearby wifi hotspots to show your location...
I noticed that on the OG Evo in Maps (Maps, not Navigate), it would usually snap-to-street while i was driving. Now it doesnt seem to, i could be doing 50 down a side street and the map shows me driving through people's back yards on that street...
I use mine for logging runs and workouts. I wasn't too impressed yesterday when Cardio Trainer logged only half of my run.
NS4G didn't do that, lol. You could see where it would pickup and drop some sort of signal, and it repeated it numerous times while walking.
Running, it seemed to hold signal decently.
::EDIT::
Went running and I think its a CardioTrainer issue, not GPS. The GPS is constantly updating it seems like, just with CT I had a setting (auto pause after 5 seconds of no running) and I don't know if because of picking up and dropping satellites or what, but it was in and out of that mode.
Disabled that option (no big deal to me if it doesn't auto pause), and had a CONSTANT lock for the rest of the run after I did so.
I can get a cold lock inside within 10secs. Outside cold lock almost instantaneous. Gps rocks in this device.

It's really good and accurate. But, I never really use it so I can save some battery life.
I've been blown away on it. Google Maps on my Palm Pre used to take over a minute to load, and in some cases wouldn't load at all. After it did, it wouldn't aquire a GPS signal. On the 3vo on the other hand, maps opens up within seconds and it also aquires a GPS signal right away. The arrow even moves around depending where the phone is pointed. Can't say I have any complaints. My favorite feature is being able to stream pandora music and telenav at the same time, and it actually fades out the music while GPS kicks in.
I've been having all sorts of trouble with GPS locks. It'll lock on fine to start, but within a few minutes of driving I'll get GPS signal lost and it'll take a long time to re-acquire. I wonder why. I may have to consider taking it for a repair/replacement if I'm the only one seeing issues. It reminds me a lot of how my 4G acted when I was using an earlier CM7 build so I attempted the ##GPSCLRX#, but that didn't seem to solve anything.

I drove from Buffalo, NY to Summerville, SC and back last week (900+ miles) and my GPS was spot on the entire time. While in SC I used it to get everywhere and it was perfect.
Mine grabbed me within 5 meters. Spot On.
I used Cardio Trainer also and it was very inaccurate. I watched the signal jump all over the place, it was terrible. I took it back to Sprint and they reluctantly swapped it out. I haven't tested it yet. Others, please test walking or running. I will be taking it back and going back to my EVO 4G if it is not fixed. My EVO 4G worked flawlessly.
you can only test something like gps when your driving and have time to set it up, wait for lock, yadda yadda yadda...
on the three occasions that i have used it it consistantly dropped signal and was a PITA. as for gps... I prefer the 4g not the 3d
Strange...

My GPS has been working flawlessly since purchase. I play golf and use the Golf Card app and was very happy with the accurate results. However, today....the GPS was acting wacky. It was jumping all over as described above. I reset the GPS and that didn't fix it. After playing around with the phone for awhile, I finally got it to work as normal. Keeping an eye on this in case I need to get rid of this phone.
My GPS has been about as temperamental as the OG Evo on CM7. It sometimes has trouble locking and often is fairly inaccurate (it seems to work better in Google maps than other apps). The OG Evo on sense was definitely better IMO.

The GPS is very inaccurate and jumps around constantly on Runkeeper. For example, see these runs:
http://runkeeper.com/user/rcrockett/activity/41894800
http://runkeeper.com/user/rcrockett/activity/41487967
Zoom in and you can see how it's jumping around all over the place. It makes it seem as though I am running faster and a longer distance. The first link is a 10k, but it reported it as 7.15 miles. I thought was kicking butt!
I have not taken any OTAs. I hope this is fixed sometime soon. I wonder why this hasn't been reported more.

Is Galaxy S2 GPS Navigation worthy?

Is Galaxy S2 GPS Navigation worthy?
Recently, I owned a Samsung Jack, Samsung, Captivate, and Samsung Infuse. Here's how I rate their GPS:
Jack - 8/10 - Navigation worthy
Infuse - 5/10 - Works unreliably, need to carry a 2nd GPS as backup. Infuse gets a lock in 10-15 seconds, but has a mind of it's own when it comes to tracking.
Captivate - 2/10 - Good for checking what town you are in...nothing more.
So, how's the GPS on Galaxy S2 in comparison? Do you feel comfortable taking long trips without feeling the need to carry backup GPS like Garmin/Tom-Tom?
Thanks in advance.
The GPS accuracy is good enough, but I think your question really depends on what navigation software you use.

I plan on using Google Navigation or COPILOT
The inbuilt google navigation I find excellent I drive a lot for work and it's yet to let me down. I also have the Co Pilot live app and it it's poor, often taking me strange routes and more often to the wrong destination.

Google Navigation and PAPAGO never let me down.
For me very much a working tool .

Even though my GPS accuracy is poor (according the stats) the navigation is excelent, using Google Navigation as well.
I won't lie it's piss poor compared to just about any other Android device including 1st gen devices but
with GPS status and some tweaks I can get a 5 metre "lock" which is good enough for google navigation.
Sent from my GT-I9100 using xda premium
never had any issues, locks onto gps within seconds even when im indoors. I like playing with different sat navs and have tried the google one, co pilot, ndrive, navigon, sygic and igo. All seem to work fine and keep their lock. Only difference is some slight changes in routing and graphics. I still generally go back to the google nav and /or co pilot though.
For some reason the S2 looks poor on GPSTest app which leads some to believe it's unreliable. However, using tracks and google navigation in particular it's accurate and never let me down. Much better than my SGS and ZTE Blade which both show better accuracy on the GPSTest app.
works great for me for the most part. Can be a little off i.e drive another 15 seconds up the road before the destination has arrived-thats very rare though.
i haven't used it for driving, just for google maps usage but its been pretty damn accurate
I had a slight issue where it took up to 5 minutes to get a GPS lock. I installed faster fix and change the NTP server (From US to EU) and it now gets a lock in seconds.

Very interesting. It probably means the GPS chip on S2 is better than Infuse. Infuse locks within 10-15s but is very poor when it comes to tracking. Google Navigation, COPILOT, or Tracks are not really useful in cities because they keep bouncing in a 40m radius. It can be used on a highway in limited capacity. Samsung seems to have improved the GPS chip in S2.

40m lock is what Infuse gets us while Navigating, 5m, even 10m would be sweet.
GPS works like a charm. Only issue is that sometimes it takes a little longer to lock, and I have to run Tracker Booster to lock properly. Then I can use all kinds of software (google maps, sygic, sports tracker, mytracks).
Here´s a bike ride tracked with mine. I´ve just reviewed the entire map, and can assure that it´s 90% correct. It was a cloudy day, by the way.
I press on navigation and I get Google maps navigation is not availabtle in this location (Get directions or cancel) so If i press get directions I guess it turn me into google maps, I can see myself if connected to the internet without it its bad, maybe gps is broken ?

Map My Ride woefully inaccurate?

So is this a problem with the Rezound, or the program? I went for a short 20 mile ride today, and Map My Ride showed it to be 28 miles. It's a 20 mile loop by my cycling computer and by google maps, and this is hardly a small margin of error. I've generally had good luck with the GPS but this is a little extreme.
well, one time just using the standard gps, i punched in an address & it showed it to be in the middle of a lake on the screen... õ_Ô
Solar flares interfering maybe. No, seriously they're high at the moment.
Rezound GPS is not very good with any of the sports tracking apps. Someone posted a thread where clearing agps cache helped but it didn't work for me. I still use my incredible for logging my runs. I haven't tried any of the ics roms but I'm hoping they address the problem.

The GPS on the Rezound sucks! I came from the Samsung Galaxy S and it had its GPS problems as well but it got better and better as time went along. Hopefully this will happen again. But I can be in my back yard and when I start Maps it locks right away and says 5meter accuracy, yet it shows me 100-150 feet away from where I really am. So its basically worthless. While driving it shows me driving through buildings and people's yards all the while saying its got a 5 meter accuracy lock.
Part of the problem may actually be solar flairs, but it does seem to be a larger issue of the Rezound doing fine-grained tracking. Here's my supposed ride yesterday--I was riding like a drunk sailor, apparently!
This problem has definitely been happening since before the current solar activity

I will have to try this.. I've never had a gps problem on HTC phones. On my Samsung charge.. if the wind was blowing you couodnt get a lock.. my buddies Samsung captivate can't get a lock unless he's holding still in clear view of the sky. If he's driving.. it won't lock at all.
Every HTC phone I have used locks in seconds.. every time, all the time and always accurate.
And you guys realize that if for whatever reason the GPS connot find.you, its going to triangulate off ccell towers, which is never accurate.

For clarification, this is the solar activity being referred too - http://news.blogs.cnn.com/2012/03/08/solar-storms-causing-few-problems-on-earth/
I just noticed that in GB and ICS, it seems to be having the problems start up around the same time (a little more than a minute after the screen goes off, it always seems to start out right though). I'm wondering if it has to do with the phone going to sleep or the apps not being able to prevent the phone from sleeping. I'm going to see if the problem happens if I set the phone to never sleep.

The phone was in airplane mode because there's no signal out where I was riding. Wasn't triangulating.
I think it's probably the uptick of solar flares, or there's a problem with how the Rezound tracks w/GPS. Or both.

Note that aGPS (the a is the assist part) uses the network to provide the assist to the GPS to get a lock. If you turn Airplane mode on, you are turning off part of the ability of the Assist in getting the lock faster. So you can be making the use of the GPS much less accurate as it takes longer for the GPS to get a lock.
Once the GPS gets the lock, it doesn't need the assist again, but some apps don't keep using the GPS steadily, and need to reacquire the lock over and over.
Example, if you are using Gmaps, you will notice that the GPS satellite image will show in the top of the notification area while you are using the app. But when you move away from Gmaps, the symbol disappears. That is because it stopped accessing the GPS.
If you don't see the GPS satellite in the notification area, the GPS chip is not currently being accessed and it is is using next to no power during that time.
Not being familiar with the app mentioned in the OP, you would need to check that the GPS is being used continually.
It is not unusual for stand alone GPS trackers (non-phone types) to have glitches in their tracking as you travel, depending on the speed and access to the sky for the GPS signals. Devices like Garmin compensate for that by keeping you on the road, even if the temp position places you a distance from the road so you don't notice it much there. But if you are just tracking position (no locking to a road), you will end up with jutting points that can be a distance from where you were at the time.
A nice thought, but all these app should be pulling accurate gps even if the app doesn't have the foreground and they should prevent the phone from sleeping.

So I tested the app, 'Myrun' And I found your problem. when the app is in the background, it does not update at the same rate as it does when it is in the foreground.
On my attachment, the green dot is where I started, I went out, up the road, and turned around. The screen was on this entire time, notice how accurate it tracked me. It even has me on the correct sides of the road..
at the Yellow dot, I turned the screen off, notice how it jumps from point to point , making it very inaccurate. If I had to guess, I would assume that the app either A, does not utilize the GPS radio while the phone is 'off', or, it polls it less frequently. Either way, this is not a fault of the phone, as you can navigate with the screen off accurately with google nav/maps. So the phone is capable of allowing apps to use GPS data even in an 'off' state.
I would contact the App developer and see if they can fix it. In the mean time, make sure your phone is charged 100% and set the screen to never time out, and turn the brightness all the way down and you'll get accurate tracking with those apps.
Personally, my phone is set to never turn off, and my bike has a phone mount with a charger that gets power off my front wheel hub.
So all the tracking apps have the same problem and only with the rezound but it's not the rezound?

I can test it on my DINC of you want, I have it laying around here somewhere.. give me a bit and ill run the same route using it instead
unless you want it to be the rezound and not the app
I know for a fact the incredible doesn't have a problem, because that's how I've been tracking my runs.
You should still test it though.
I wish it wasn't a problem, I love everything about this phone except for the fact that I can't use it for my running program.

What is your GPS [GLONASS] lock time?? +info on GLONASS

In case you didn't know, the Note can use GLONASS instead of GPS (Click on the words to read more).
People use GPS like "Xerox", "Coke", or "Kleenex"... but nevermind that.
What is your GPS/GLONASS lock time with A.GPS (Assisted GPS (network location)) and sensor aid on??
Please describe whether you are outside or inside. I am also particularly interested the lock time from a fresh boot or if you're using GPS from a new location.
IMPORTANT: Please note (excuse the pun) down, when you launch Maps or Nav and the arrow shows up almost instantaneously, I would like to know IF *sometimes* the GPS reticle on the status bar continues to flash/blink for a while.
Why do I ask? My Note takes anywhere from 3-12 seconds to lock when GPS is "hot" and takes 10-25 seconds to lock from a reboot in doors while stationary.
Compared to my Sprint Evo 3D, GSM Galaxy Nexus, or the iPhone4s that I never use, that is slow. When I powered up the Galaxy Nexus for the first time, it locked under 5 seconds! My Evo 3D would lock from a boot in under 5 seconds. The 4s is super fast also. The Note, with GLONASS, is supposed to be faster and more accurate...
Thanks.
Edit: Interesting discovery today--the slow lock and low precision in my car may be because of my car--but it may also be revealing limitations in GLONASS:
Every piece of glass on my car is double-paned (twice as thick as the typical car glass), sandwiched with a polymer layer, along with an IR rejecting coating. This is designed to keep the interior very quiet, makes the glass theft resistant, and the IR coating reduces the heat that enters the cabin (heat travels in the form of infrared). The IR coating, unfortunately, also rejects other radio frequencies in the electromagnetic spectrum. That, along with metallic particularized tint, causes a reduced radio performance for any device that is in the interior of the vehicle.
I usually don't have any problems with the GSM/UMTS or CDMA phones, and GPS has no problems either (although I notice a reduced s/n ratio). As I indicated before, other GPS-based phones lock fine, and the GPS+GLONASS iPhone works fine also.
As I was driving home today, I tried opening the window. I noticed that every time I opened, the phone would get a quick and solid lock. Every time I closed, the uncertainty circle appears.
Is it possible that GLONASS, operating at 1.6Ghz, using FDMA is less able to penetrate certain objects than GPS operating at 1.57Ghz using CDMA? I presume civilians are still only using the coarse channels so that doesn't help. It is interesting to see that GPS have no problems in my car while GLONASS does. I will drive another car tomorrow and see if there is a difference.
My Note locked within 2 seconds this morning, on my way to work. I was outside in my car.
When opening google maps, I get a lock before the app is fully open, ie. I'm already locked by the time I can do anything in the app even. Compared to my Captivate and Infuse, the lock times on my Note are godly.

I lock before apps load that can use it such as maps/nav. I came from a Vibrant that even after numerous "fixes" it still could take a couple minutes to lock.
Wow... That is what I expected from my phone. Are you guys all using the stock ROM? If not, what ROM are you using and who is your carrier?
Thanks.

same experience here,running stock
No, not stock. I'm highly modified. I installed a screen protector that I suspect is giving me increased GPS/glonass capabilities.

Hmmm... maybe it's *my* screen protector that is killing the GPS...
A follow up to those who responded:

Thanks for the information.
I was excited for the GPS capabilities in this phone before I bought it, but my experiences have been far worse than everyone elses. Google Maps is loaded for about 5 seconds before it even STARTS trying to acquire a position. And even then, while indoors it takes a good 20 seconds to lock on. My iPhone 4 locks on indoors in about 3-5 seconds.
With the note, many apps think I'm 10-15 miles away while indoors. Especially with weather apps that just want a quick location fix but don't leave the GPS on during use. At first glance everything thinks I'm far away. Chat apps that only use GPS when sending a message have the same problem. Navigation apps that leave the GPS on during use are accurate. It's annoying. Never had an issue like that on my old phone.
Outside though, the Note seems to lock on nice and quick, within about 2-3 seconds upon starting acquisition, and my accuracy is generally at 3 meters or less. Even my $650 handheld GPSr doesn't have that level of accuracy.
EDIT: The notification bar icon DOES continue to blink for several seconds after achieving a lock.

As for accuracy, this is a function of the number of satilites that you have locked onto. I believe all you need are 2, possibly 3 for accurate elevation, however the more you lock onto the more acurate you are. This is why "quick" on and off checks are rarely very accurate. however, with weather, the phone grabs your location and then queries the closest whether center, which is very rarely in your neighborhood. Typically it's your closest airport or military base, so this will atleast be 20-30 miles away, but often in same or neighboring zip codes.
For the indoor, thing, I never expect (nor really use) reliable GPS signal indoords. Just because you get a lock doesn't mean it'll be enough locks to do much. I rarely get lost going from my kitchen to the latrine anyways, but I suppose with enough beer it could happen. I would suggest (and you probably already have) check to make sure you make use of "use sensor aiding" option.
If all else fails, I will loan you my vibrant and you can experience a man-tantrum in your car when the fking thing wont lock after 5 minutes and your lost as **** and late as hell and google maps keeps freezing and FCing. That'll make you want to wine and dine your other devices for treating you so well.

I believe you need at least 3 for triangulation (location) and 4th to give elevation.
Another interesting thing I noticed about my Note--even if it locks quickly while I am stationary, it looses lock when I am moving (driving). I had my Sprint Evo 3D, Verizon Galaxy Nexus, Sprint Galaxy S Epic 4G, GSM Galaxy Nexus, and the Note side-by-side on the dash. The only phone that keeps losing and reacquiring the lock the the Note (especially while traveling at freeway speeds).
my note locks on really fast
under 10 seconds for sure.
If im out side its within 5 seconds.
My Skyrocket usually locked in around 10-15 seconds
my inspire....30 seconds.
my nav in the car....30 sec

Very useful tool. In addition to that one, I also use GPS Test, GPS Essentials, and GPS Status. Each brings something different to the party.

Sounds like you need "Kick GPS - The 12 Step Program"
Really? Your complaining about 12 seconds to a gps lock? (regarding the OP)
Give me a break...
My DEDICATED GPS Tomtom unit takes over 2 minutes to get a lock, I consider it a blessing that my phone locks faster than a dedicated gps.
Good Lord...
My guess is you are one of those that complain about your browser taking more than 2 seconds to load as well.
Regarding gps stability, there are a couple of different things to try, namely one of the more rare things is calibrating the compass. There are many videos on Youtube, just search 'smart phone calibrate compass'. You'll find 3-4 different methods, any will likely work. And yes, the compass does affect the gps keeping a lock in speeds higher than 20 mph.
Another thing to try is downloading the latest gps satellite data. There are several apps available on the market that can do this (GPS Test, GPS Essentials, and GPS Status all do this).

Why so excitable and quick to judge? "Give me a break..."? "Good Lord..."? Really?
Your TomTom uses GPS, not GLONASS and does not have Assisted GPS. GLONASS and A.GPS should allow a faster fix. With these new and additional technologies, the phone SHOULD get a much faster fix than your TomTom. You're comparing apples and oranges.
My Evo 3D, Galaxy Nexus, and other phones I metioned, with GPS (no GLONASS) and A.GPS will almost ALWAYS get a fix in 2-5 seconds. If enough research is done here at XDA, you will find that many newer devices, if working properly, *should* get a lock in under ten seconds. Your "DEDICATED GPS Tomtom" [sic] is a different and arguably less advanced animal.
Another example--the built-in GPS in my two vehicles lock IMMEDIATELY when the car is on. Why? Because they remember the last location, use brake sensors, steering angle sensors, and accelerometers to determine location. If they do not lock immediately, something is wrong.
If you re-read my original post--I am trying to figure out if others have the same problem, and attempting to understand what others are experiencing. At the same time, I provided information on GLONASS, in case other owners didn't know they had it.
For a just-released, $650 device, I expected mine to perform on-par with other phones. Perhaps mine is defective? I wanted to find out if I need a replacement. Last checked, this forum is about people asking questions, sharing information, and learning something. To that end, I am puzzled at your comments--it seems like *you're* the one who is complaining...
So yes, really!

Yes, I suppose...
While I'm her--there is also F GPS (fake GPS, provides coordinate of your choice to the location manager), GPS to MMS (allows you to send a text/MMS with your current coordinates), and GPS Speedo (a nice GPS-based speedometer).
See the edited OP. I made an interesting observation today. It seems like GLONASS signals are less able to penetrate objects...
My Note's GPS performance is flawless and is my most loved feature of the device. Superquick and very accurate.
I use the GPS all the time for backpacking, motorcycling, running and of course general finding all the stores my wife makes me take her shopping on the weekend.
Even better than my previous iPhone 4 and 3g.
My Samsung Infuse's GPS was a disaster taking forever getting a lock, loosing it, placing on the next road over, and not performing if sitting in the middle of my car...constant frustration so I REALLY am happy with my stock Notes GPS.
