Hello,
Ive just bought SGS2 and a few hours later I bought Sygic Aura from the market. I downloaded map for my country and... Gps is not able to catch fix. Ive tried with google maps,also very inaccurate reading. I downloaded gps test from the market and 20 meteres accuracy is obtained in a few seconds. What can be a problem?
Does it mean that Aura does not work with SGS2 or Gps does not work properly?
any suggestions?

Either or both.
First step is to lock satellites GPS test.
Followed by let Google maps find position .

Same for me.
Normally I get 8-20m of accuracy
As 8 meters can be acceptable,the biggest problem is that Aura cannot even work. I have tried for 30 minutes to get fix with clear sky without any results.

Even without being very happy with the accuracy of my SGS2 (fluctuating between 8-20m as I told before), I don't have any problem with Aura navigator.

8m accuracy is more or less the best you can get with GPS, please understand that the reported accuracy is an estimated limit of the accuracy, and the position is often better than 8 meter off when accuracy is reported as 8 meter (but you cannot be sure of course). This is simply the limitation of the GPS system.
So an accuracy between 8-20 meter is really good for any GPS receiver.

Yes, but my old HTC Desire had an average of <5 meters all the time.

On my Nexus One, GPS would acquire location within 50-100' accuracy within 15-30 seconds of being activated in Google Maps or the Instamapper.com GPS Tracker App.
On the Thunderbolt, it is taking on average about 2 MINUTES for initial location acquisition.
Has anyone else noticed this terrible lag in GPS?
mine takes about 30 seconds to lock. this is WAY better than my vibrant which NEVER locked be happy lol
Only inside my work building. At my vehicle.. Not bad
Outdoors I lock in less than 15 seconds....
My initial GPS locks were incredibly slow
Initially the first few locks were slow, but now it's not a problem.
Mine is very fast.. just about as fast as my Garmin
Mine locks within seconds in my house, pretty much immediately outside.
In addition to having your GPS powered on, make sure you have Google and VZW location services enabled.
Immediately

No problem.
As I understand it:
Standalone GPS = The actual GPS antenna.
VZW location services = Uses verizon towers to get a general location
Google location services = Uses wireless networks to get a general location (more accurate than VZW services).
Once the general location is obtained, it can get a GPS lock quickly.

I'm sure everyone knows about the GPS bugs that plague the first generation Galaxy S. I've read the SGS 2 reviews and they said the GPS issues have been fixed, but can I get some opinions on whether anyone experienced any GPS issues? Is the GPS on the SGS 2 as accurate and good as the one on the iPhone 4?
Works fine. Faster lock than my IP4.
Its much faster than the Galaxy S1. I found the GPS to be close to useless on S1. On my S2 its close to perfect

Works great and picks up signals inside buildings.
I had the sgs1 for about 6 months and now the sgs2 for about 3 weeks. I was soooo disappointed with the first sgs and like you I was unsure if I wanted to give the 2 a try...
Well I read a bunch and it seems that most people are happy so I bought it...
I can say with out a doubt that the GPS is way better on the 2 than the sgs1. I could not use Google navigation at all with the sgs1... it was useless and could never lock on and would have me blocks away from where I was. I've used my sgs2 GPS with Google navigation on more than a dozen trips /drives and it has always been spot on and never had me in the wrong location.
I will say that lock times are very slow when Im driving

I run every other day for an hour or two, I use runkeeper, also when out hiking I use mmtracker to read my o's maps, I can safely say especially with runkeeper the gpx routes recorded through the SGS2 are far more accurate than the iphone4 even managing to stay accurate whilst running through the forest, actual initial cold starting is about the same if not slightly faster with the sgs2. Oh yes and practically every time I recorded a run with the iphone4 through a certain part of my forest run it would create a spike where I was apparently running at 250mph hmm not sure I am that fast, but the sgs2 always keeps an accurate smooth record, hope that helps
for me, flaky. some days i'll get a lock within a minute and then it's fine. this morn and yest - takes ages to get a lock.
basically, ymmv
Download FasterFix. You can choose from a list of servers. Choose the country closest to you or, if it is in the list, your own country. This way you'll 'half your fixtime' so it connects faster to GPS-Sat.
It's like using the aiding sensors (e.g. WiFi).
I get a fix in >10sec max.
Hope it helps.

i think gps on SG2 is far from perfect. It's "OK" but i had much better gps on my previous phone (HTC Hero)
What is the average time for a fix, for you guys?
Sent from my GT-I9100 using XDA App
Mine takes between 10 seconds and a minute. Sometimes it just sits there doing nowt lol.
Xperia X10 used to lock in 10 seconds every time, but the rest of that phone was slow lol
The only time I have ever had a problem getting a fix, I simply opened up google maps and it seemed to get a fix instantly then returned to my other gps application and all was ok.
First thing in the morning outside fix within a few seconds
Indoors sometimes can take a little longer, but never more than about 10 seconds
I use GPS a lot

I guess you said this to clarify that you've got good statistics, but a very interesting thing is that if you use the GPS often you likely get shorter fix time
The reason is that if you used the GPS recently (within hours) the cached GPS info is more accurate so the GPS doesn't need complete messsages to determine the position (it takes 30 seconds to send one complete position message from a satellite), and if you get interruptions you need to wait even longer, that is why it sometimes takes more than a minute to get a fix.
A-GPS also helps fix time in many cases.

Same thing happened to me.
Absolutely brilliant.
90% of the time it gets a lock within 30 secs , there's been sometimes when it needed a restart to get gps working properly but that's down to an app I was using previously which messed things up a bit, but on the whole I very happy with it.
The seamless integration with google maps is great. The external speaker is plenty loud & clear enough to hear the instructions but would like a less robotic sounding voice, re routing is quick & so far its been 100% reliable.
I have a built in gps system on my Land Rover but I almost always use the SGS2 gps over it. I used to have the SGS1 but the gps on that was a piece of crap. Gps on HTCs, etc, are probably just as good/better/worse, I don't know but one thing I'm sure about is the speaker volume would never be as loud & clear as the SGS2.
I get a lock up to 4m accuracy. My Captivate always had about 1500m accuracy and couldn't use it. Using navigation works perfectly on my sgs2

Excellent
Like others here, i suffered from the original SGS gps nightmare
SGS2 gps has been great for me, able to use google maps/navigation/RAC app all without problem
I didn't realise how much location based services I used untill the problems with SGS gps clearly highlighted this. Now, with my SGS2 all is good.
Is there an app like the LBStesmode for froyo that I can use to change/check the gps settings?
i made a little test with Endomondo sport tracking application to see how accurate my gps is. I walked the straight street for 0.64 kilometers and this is what it looks like:
http://www.endomondo.com/workouts/ilRz0mnqvJA
I was wondering if that is normal or should it be more accurate? Or can i make it more accurate?
edit: don't mind about the duration, i forgot to turn the app off when i got inside!
My GPS isn't very accurate, but I am in the heart of Hong Kong, so I can't expect it to work well with so much interference. It would detect my exact location in Maps, but it the blue arrow won't lock, and jumps around to as far as two blocks away.
I've tried some gps improvement apps, but they do not work for me.
mine sgs2 does not have very good acuracy. My old htc desire was very acurated compared with sgs2

Wow, sorry but i kinda laugh when i saw the ziggyzag lines. No, the GPS shouldn't be that way, I've used mine several times while driving and it just flows smoothly, like a real GPS device! Once I even had 10 out of 10 satellites locked in a few seconds!
Maybe the GPS in your phone is defective or something, I say exchange your unit for a new one. Hopefully it's still under warranty

You cannot tell that from that log. It depends on the circumstances, e g bad reception due to high buildings can easily cause problems like this.
I suggest jankher does some more tests in others locations.

Interested in this thread.
I've had my SGS2 for a couple of weeks and have been testing the GPS for accuracy. From my experiences, the accuracy is OK when you are using a 'proper' satnav app (e.g. CoPilot) as the system knows to try and keep the arrow in the middle of the road.
However, one of my hobbies is Geocaching which I need an accurate GPS for and here's where I have had real problems. At a known cache location (i.e. standing exactly on top of it), my SGS2 showed 5 sats locked on, 25m accuracy & 32m to the cache !!! My HTC Wildfire (in my other hand) showed 8 sats locked on, 2m accuracy & 1m to cache.
Time to read more threads and see if this can be improved by software or if I'll have to think about keeping the HTC for caching (which would annoy my 11 year old who now has it) or consider selling the SGS2 and getting a HTC Sensation or Motorola Atrix.
Hello
Is it only me or I'm having issues with GPS takes a lot of time to fix and also the position is far beyond invalid
It used to be so good with my x10(the only thing I feel it lags on my s2) I'm a traveller and I find Google maps much useful and I'm lost without it. Can anyone help?
Also I've tried changing ndp using fasterfix from the market. Any help would be appreciated

When you bought the phone and got it home did you take the phone outside and wave to the man in the satellite to let him know you should be on his connection list .

Well problem for me too..takes around 5 to 7 mins to get a lock...once it does its fine though...m on stock ke8...should rooting or updating software improve this?

Check your A-GPS server. I had very poor performance using the normal A-GPS location servers but then changed it to xtra1.gpsonextra.net using FasterFix and now it locks much much quicker and the accuracy has improved (my location is no longer 20 meters away from where I actually am).
Hi,
I am KI3 and lives in chennai...
i have no issues with GPS...its gets a better accuracy like 3-4 mtrs outside my apartment.....inside my home, its kind of Ok, but i will live with it...why i need gps inside my home
and i always use directions>maps whenever i want to goto some place and till now my SGS2 baby it never let me down....she will come and direct me whereever i want to go....
may be try flashing KI3.....
Gps works awesome for me in delhi.no issues at all
