What is your GPS [GLONASS] lock time?? +info on GLONASS - AT&T Samsung Galaxy Note I717

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.

A follow up to those who responded:
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.
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

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!

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.

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???

[Q] question about GPS - why no lock at 4 sats?

it takes a while sometimes to get a lock (other times very quick) but once it gets a lock, it takes a lot to get rid of it.
my question is, why can't it get a lock at say 4 sats after turning on gps ? there's enough data there, it would just be inacurate
i'd also like to know if there's a way to force a lock asap as opposed to waiting for a decent level of accuracy
lock does not happen merely because your device can "see" 4 sats. for example, while in a plane at 10k meters, i can see sometimes even 11 sats but there is no chance to get a lock. so i guess there are a lot of factors that influence getting a lock.

Well, attached are two screenshots made with my ex-HTC Desire I made on my flight to Hannover...
How/where can you see the number of sats your GPS has locked on? I never found the option on my phone...
yea, and my desire got a lock on flights to cuba and canada.
afaik, it should be able to get a lock based on seeing a few sats. gps is based around the time it takes for a signal from a sat to reach your phone and comparing the difference between the connection time of each sat the phone can see right?
even with 4 sats, there should be "some" data. it would be ranging to a few hundred meters but should still have something.

what app do you use? pretty much everything i've seen/used tells you.
Your question is not about SGS2 but about the GPS-system.
In order to calculate position the receiver needs certain information, and it takes some time to send out this data. The data rate from a satellite is only 50 bit/s!! (yes, I mean only fifty single bits per second...).
And when you only see 3 or 4 satellites, then it is often satellites that are visible in the same area of the sky, and that makes it difficult to calculate the position.
Here are some information how this works:

The only apps I use which require positionning are Google Maps, and Dolphin HS browser (some websites, such as google, give you informations adapted to your position). I did not find, in Google Maps, any info on the number of sattelites.

That´s the way GPS-positioning works.
Your device measures the time the signal takes from the satellite to the GPS-reciever.
The time it takes for the signal is dependent on the distance between you and the satellite.
But calculate the distance and make something useful from it the device needs some information. First it needs to know the actual GPS-time. This must be very accurate, as the signal travels with the speed of light a very small error makes a big difference. Therefore it can´t simply use the internal clock.
It also must know the exact position from the satellite, so the distance can actually be used to calculate your position.
So the satellites constantly send a signal consisting of their ID, the time the signal was sent (all GPS-satellites are synchronized) and the current position of all GPS-satellites in the air. GPS-satellites aren´t geostationary, they are constantly moving around the world. Therefore on the same position on the earth you can experience very different GPS signal-strengths and different numbers of satellites you can receive, depending how the positions of the satellites are when you are using your GPS-receiver.
But GPS is very old and the signal is very weak, the data-rate is very very low. It is so low, if you had a GPS-antenna in your body, you could nearly count the bits yourself.
So it takes a lot of time to get the whole position-data transmitted and until the necessary position-data from the satellites is not on your device it is impossibly to calculate your position.
There is no backward-channel, so you can´t tell the satellite "please send me this", you simply have to wait until the satellite sends what you need. And if the signal was interrupted for a short period you can´t tell the satellite to resend the necessary information, you have to wait for the next round.
This is also what assisted-GPS can speed up. With A-GPS the satellite-positions are sent over the data-connection to your device, so it can speed-up the lock quite a bit, because your phone can almost immediately begin to calculate the position and does not have to wait for the satellites to send their position-data.
In the end you have a system of equations with 4 variables. The variables are the 3 space-coordinates, and what many people forget in first sight, the time.
To solve a system with 4 variables you need 3 equations -> 4 satellites.
More satellites can be used to increase accuracy, but they usually won´t speed up the initial lock a lot.
After the initial lock your device can interpolate the travel of the satellites, as well as the time, so 3 satellites are enough to recalculate the current position.
This is also the reason why the initial time for the initial lock depends highly when you last used the GPS. The satellite-positions can be interpolated with reasonable accuracy for a few hours. So if you use the GPS once every hour, lock usually will be quite fast. If you didn´t use the GPS for several days, the lock will take longer.
my question is, why can't it get a lock at say 4 sats after turning on gps ? there's enough data there, it would just be inacurate
Click to expand...
Click to collapse
Read above, there isn´t enough data there, as long as the device doesn´t know the position of this 4 satellites.
Also it doesn´t really matter how many satellites you have to get the lock, actually 4 strong signals would be better then 10 very weak signals.
You also shouldn´t move around until you get the lock. Getting a lock in a driving car can take a very long time. First of all, the car blocks much of the satellites signals, the windows are the only chance to get some of the signals into the car, and if you drive around you will constantly lose one satellite and get to the next one. So much of the position-data will have to be sent several times, until your device gets all the necessary information.
i'd also like to know if there's a way to force a lock asap as opposed to waiting for a decent level of accuracy

No, not with GPS, you can use Cell-tower information, which allows positioning with very low to medium accuracy. WLANs could also be used, but aren´t always available.
thanks
so, do you think galileo will be a better alternative once finished?
more probs with this today.
stood still for about 5 mins and no lock. tried different roms, data on, no diff
gps just sucks
Get GPSTest app .. have data active (wifi works too) .. go to gps test app settings, select clear agps, then update agps .. then you should get fix in few seconds.
got em. a few of them actually. did that. doesn't work at times. it's annoying.
thankfully i don't use gps properly all that often but if i ever really needed it (for work or soemthing) i'd get something standalone. can't rely on a mobile phones gps at all

Moving to Q&A

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.

can you elaborate?
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.
Sent from my GT-I9100 using XDA App
Google Navigation and PAPAGO never let me down.
For me very much a working tool .
jje
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.

with GPS status and some tweaks I can get a 5 metre "lock" which is good enough for google navigation.

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 ?

i had that no matter what i did.. sometimes up to 1-2 minutes to get a lock..
it is finally fixed in ics.. in lp6 i get locks in 10-15 secs. as i should and get on my old sgs.

More GPS info please

With the results of the vote in the GPS (possible issue) thread running at 30% functionality, left me asking what are the other 70% of us doing wrong?
I thought this would be an opportunity to gather data for analysis. It is not a chat thread or for discussion on causes, or trouble shooting.
Just maybe something well show up, as it appears Asus doesn’t have a clue and keep blaming the case. While the case does seem to be attenuating the signal compared to my Samsung Galaxy S2 it doesn’t explain the hit and miss nature of the TF201. And we all have the same back panel on our TF201’s.
On one occasion with the TF201 sitting on a park bench found 9 Satellites and used 5. (Using GPS version V 6.8.13) Without touching a thing they all disappeared. Then nothing!
The best I can do now is 1 Satellite found.
Test procedure:
Outdoors only in a wide open space.
Use “GPS Test” from The Market.
Update AGPS then turn Wi-Fi off.
If all reports could be posted in the following format.
1. Model:
2. Build:
3. GPS Version:
4. Satellite’s in view:
5. Satellite’s In use:
6. Time to first fix:
7. Has the GPS worked in previous builds of ICS
8. Did GPS work in Honeycomb
9. First 8 digits of serial No
Just maybe a pattern will emerge.
Thanks all.
1. Model: 64Gb Champagne
2. Build: IML74K.TW_epad 9.4.2.11
3. GPS Version: V6.9.13
4. Satellite’s in view: 1
5. Satellite’s In use:0
6. Time to first fix: N/A
7. Has the GPS worked in previous builds of ICS: Yes briefly
8. Did GPS work in Honeycomb: Not tested
9. BCOKAS08
Not sure what you're trying to accomplish here.
There isn't a single Transformer Prime on this planet where GPS works great.
So It is what it is: the metal design is beautiful, but it restricts GPS signals. And as there is no real a-GPS for Wifi tablets(as they have no cell-site triangulation possibilities), this becomes a real and unsolvable problem.
And Asus DOES has a clue, according to Asus there is no GPS on the Transformer Prime. The same as there is no GPS on other Wifi tablets like the iPad's. Asus made a big mistake advertising with GPS before release though.
So if you really want to use GPS on the Prime, you're out of luck and should return it. A full refund would be fair if you bought it early.
I've never been able to lock onto more than 3 and then for only a few seconds. That was with HC and now ICS. If I use my Prime for navigation I use my BT GPS receiver and a full mapping capable app which I've already tested and works great. I suggest if anyone bought a TP for navigational purposes return it immediately.
Non-issue (for me at least).

Ohh really.
Please explain TF201 sitting on park bench found 9 satellites, using 5.
Without touching the device all satellites lost and no further seen.
Don't like the odds on those condoms.
The aluminium case explains the poor signal to noise ratios, not the sudden loss of all reception on a stationary device.

The same reason when you are on the edge of losing a FM or AM radio station it can be crystal clear with a inch of movement. Try to navigate turn by turn with the Primes GPS as soon as you start moving signal is too weak to keep it. If your device just dropped all satellites without any movement it's just a glitch and has nothing to do with the overall problem of the Primes GPS.

Because it sees them but fails to hold them when moving because the signal is weak.. Why can't people accept that?

Yes, this has been pointed out about the aluminum back. But as mentioned we all have the same aluminum back then ...
WHY are some Primes always able to see and get a GPS fix.
Why is ASUS even bothering with updating the GPS driver if GPS in not in the spec's?.
WHY has someone not show GPS results with the aluminum back off?
Off topic WIFI why the frack would I want to use G setting to get good WIFI? That's like not using my 5th gear in the car and staying in 4th.
I love the Prime but the aluminum back shield is a frack up period. Stock seems to have dried up around here (impossible to get). I wonder what's up.
My new Prime had never seen 1 single satellite for the 4 days or so I have had it.
Last night, I open Google Maps and click on Resteraunts and simply pick a Pizza Joint nearby. Then I click on NAVIGATE for it to navigate me there (I was just playing around on my couch in my living room, not in my car).
The bottom of Google Maps said "Searching For GPS" and I said "Fudge It" and just laid it on the coffee table. I closed my eyes and about 12 minutes later (I looked at the clock) my tablet says in a woman's voice "Turn Left on Birch Drive!"
I couldn't believe my ears. I quickly opened GPSStatus, GPS FIX, all that. Then I noticed that Google Maps said "Searching for GPS" again. Google Maps needs a lock to navigate you so It actually got a lock for a split second, which was exciting.
However, the other apps were showing 4-5 Satellites, and they have never shown one before. It wouldn't lock, but the fact it was all the sudden showing some satellites was quite exciting since my GPS had appeared to be Dead on Arrival.
So, if you have time and can stop playing with the tablet, set up a route on Google Maps, choose for NAVIGATION, and set it down, maybe by a window, and wait 15 minutes. Maybe you will get a lock.
In my opinion, my GPS works VERY SLOW. It took literally 10 or more minutes to see any satellites, then started loading a few more slowly till I got up to 5. Again,I couldn't get it to lock onto any anymore, but I was in my living room and I have 14 mature trees in my yard (I am talking BIG trees).
Maybe give that a shot and see what happens. Because my tablet had seen NOTHING ever, but I was only trying it for 5 minutes at a time then I would get pissed.

All Primes will see and get GPS fixes NONE of them will keep it awhile moving.
No one wants to destroy a $500 device but if your willing feel free.
G gets better range with Wi-Fi in general and the Prime lacks good range with it's Wi-Fi for the same reason GPS sucks the aluminum sheild if it's not good enough for you return .

Not true!
My Prime must be bad unit because 97 percent of the time it never sees any satellites and it has had actually only had a fix maybe three times out of 100 tries.
I'd be happy to get a fix period each time I tried
Hence my original WHY with the same aluminum back can some Primes get fixes while others don't even now satellites exist in orbit?
My bad unit is going back. I'll wait for the 700 series or a revised TF201 with a new back. Until then My HP Touchpad running ICS will do for now. Yes, no HD video or camera but that's fine.
GPS works on all other sanctioned Android tablets (with market access).

Sorry I forgot to mention asus terrible qc on the primes I'm sure there's plenty where gps is totally borked bottom line is gps will never function as a turn by turn on primes with aluminum backplates. End of story
look at my youtube video... it was honey comb and nearly perfect...
with new updated ics its worthless...
I don't see any satellites and I have never seen any on either of my TFP's. I have owned 2 so far and they both didn't see any satellites period. My GPS light stayed yellow and never went green no matter if I used wifi or not. So why is mine not seeing any Sat's, but you guys complain when you have a weak signal. I am in the process of trying to return mine I bought from BB, but I am waiting my 14 days to see if they will get some in stock. If they do, the customer rep will send one out to me or the store nearest me, and then I would have to send mine off. That's what the customer service rep told me to do. It's not that big of a deal to me, but the unknown serial was, so that's why I got rid of my first one.

wrong. I get no gps satellites period .. no fix no nothing... no matter which configuration i try
Well generally not the responses I had hoped for.

What does stationary device, placed on park bench, mean to you?
Not moving...9 satellites, with a fix, then suddenly nothing. No satellites in range. TF201 still sitting on park bench!
As an aside my Wifi is perfect. In fact better signal strength and bandwidth better than both my phones and similar to my laptop.
I don't want turn by turn navigation (have TomTom for that). Just a occasional fix on Google maps. Wifi is generally too inaccurate.
And I do know a little about GPS. RAIM, FDE and Baro aiding help keep me alive in my 9-5 job.
If you are happy with your prime great.
But do check the bottom of the box your Prime came in. The spec still show GPS. Mine is a late model Prime. So regardless of Asus removing it from the web site I feel I am entitled to some form of GPS functionality.
Happy to do that Wifi assisted and it should work in a wide open space. But it doesn't for 70% of owners.
So my question once again why are the other 30% of TF201's offering some sort of GPS functionality?

I also wonder about this. Why waste the time and effort?
Here's how i fixed my GPS problem:
I pulled out my Galaxy SII. Got a fix in 2 seconds.
True Story.
i can get about a 20m accuracy lock while indoors in a matter of seconds, but it never improves in accuracy.
Satellite’s in view: 0-4
Satellite’s In use: 0
Time to first fix: 2minutes
1. Model: 32 Champ
2. Build: IML74k.US_epad-9.4.2.11-20120117
3. GPS Version:V6.1.1.17
4. Satellite’s in view: Fluctuates but up to 11
5. Satellite’s In use:Fluctuates but up to 6
6. Time to first fix:3 mins
7. Has the GPS worked in previous builds of ICS: n/a
8. Did GPS work in Honeycomb:Yes and Much better before
9. First 8 digits of serial #: BCOKAS02
In Honeycomb It was working very well but since the update its way more flaky, as it will go from 9 sats in view and suddenly lose them all.
#### Any one else notice that the GPS Icon Doesn't Blink anymore unless you click the clock menu and then go back####

the GPS is not accurate at all!

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.

Ya man. Something, whether a setting or hardware issue, is definitely buggered. My GPS is hardcore accurate. I've done 2 runs with mine using MyTracks and its dead-on accurate.

I used it with telenav from NJ to NY and it worked great!
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.
What do you have in your pockets?????!!!!!!
