GPS receiver chip is not the cause of the problem

Guys,
According to this site, the problem with the GPS is the software Google Maps
Read this:
http://samsungi9000galaxys.com/galaxy-s-gps-review-sygic-gps-signal-and-gps-lock-times/
So it seems that using other Navigation software gives very good GPS performance.....
But how come using the GPS TEST software also shows that the GPS is loosing sattelites lock and erratic performance? I mean if the cause of the problem is the Google Map, testing the GPS receiver using GPS TEST should show good signal lock and stable reception isnt it?

It's a software setting: http://forum.xda-developers.com/showthread.php?p=7281059
Other android devices have the same problem with a wrong setting.

Its not true, I tried google maps, co-pilot and NDrive and all gave really, really crappy gps performance. Upgrading to JG5 firmware has improved things a lot but its still pretty unusable for me.

You know I was just about to post that I think the issue is with google maps and not the phone. If I apply the ntp europe fix my gps locks very quickly and stays locked to within 16 feet in gps test when driving about.within google maps navigation the performance remains as shocking. Arrrggghhh!

I wish i could help testing the phone with different GPS/navigation software to validate the analysis, but I already sold my phone last week out of desperation due to the the GPS problem and lag problem and phone freeze problem and signal drop problem when you hold it a certain way....
but i love the design, size of the screen, the thinness of the phone and the super amoled display.....

Ouch...
Why did you not return your phone instead? I have never had my SGS freeze and I have never been able to drop a call by cupping the antenna, altough the signal strength does go down, wich it will on ALL phones with built in antennas since you are shilding the antenna... ( NOT SAME AS IPHONE4 design flaw where you shortcircuit 2 different antennas and that part seems particulary hard to grasp for some on this forum....)
But, to get on subject again, the GPS has been bad, that is for sure and I hope this is a step in the right direction.

Its clear that testing the gps is waaay too subjective and subject to too many factors. Applications have no effect on the gps performance.

My gps has been working perfectly with 3 firmwares.. it's much faster then the one on my old iphone 3G

My GPS seems to be very hit and miss, but it has worked on the several occasions that I have really needed it (getting lost).
And widjaja why are you still shambling about this forum when you sold your phone? get back under your bridge.

Once again, another thread started because someone made one change, tested it and it worked, then posted how great it was. Trouble is since the GPS can work fine for days on end, and then not work for days on end, these supposed cures are pretty much all wrong.
The GPS doesnt work, and so far there hasnt been a public explaination as to why, just lots of guesswork, and no fix has been released (in any of the firmwares available today). It's coming, but its not here yet.

Seems some phones work some dont.On jf3 my gps was shocking but on jg5 it has always been spot on with google navigation and co pilot and ive tested it a lot in all weathers.It has never lost lock and is always bang on with position.I even tested google maps satalite view in the car parked next to a tree and it had me right next to the tree-within 10 feet accuracy.I dont change any settings just leave it on whatever settings jg5 uses.Im in england if that makes any difference

Found a fix on another forum and its been working pretty well for me.
Enter *#*#1472365#*#* in the dialer to enter GPS settings and change the following:
Application Settings:
Operation Mode - MS Based
Use SkyHook - ON
Accuracy - 30
SUPL/CP Settings :
Server - supl.google.com
Server Port - 7276
SUPL Secure Socket - OFF
I was having problems with 3G and WIFI with these settings at first, so I left Operation Mode on Standalone and Skyhook OFF. Works great now. Just tested it and got 9 satellite locks and 5 in use.

I'm in Hong Kong btw running local JF7 firmware. Hope this helps.

I'm almost convinced that most of the problems people are having is down to google maps. I'm not saying that tweaking the settings as people have, inc me, doesn't improve maters, but I believe there is an underlying compatibility issue between google maps and the galaxy which is making the issue seem worse than it is.
If I leave gps test running while driving I get at worst a lock down to 32 feet, speed is accurate and never lose lock even when on roads totally covered with big wet trees. It looks spot on.
Google maps navigation can't even get me in an accurate position when stationary, start driving and its bloody awful jumps all over the place and sometimes doesn't even move for 30 seconds after I've pulled away from a junction.
I've updated my supl settings to use google (manually edited the conf file, I don't use the hidden menu screen because even if you change nothing it makes changes to the conf file on exit, delete the file and reboot to refresh it) and updated my ntp settings to use europe.
In the jg5 rom google maps is built in, so I can't reinstall it or seem to be able to clear the cache to see if that helps in anyway.
It wouldn't surprise me if any gps fixed rom released by samsung contains a tweaked version of google maps that works.

[Q] Sygic Aura for Android

I’m using Sygic Aura.
Have a few question. I guess they are pretty general:
Can I change voices in some way?
When I try and navigate to a contact, I have to update its position in the program. Is there a way to get it to understand the contact address right away?
When I’m using Sygic Aura and is logged in to their live service I see pictures of certain locations (they appear as icon sized pictures). Can I preview the in a larger format in some way?
Anyone here have a clue?

I'm having problems with mine. The software installs correctly, but cannot get a GPS fix, which keeps flicking on and off so that the map display constantly jumps between active coloured map and greyed out maps when the GPS signal disconnects. I'm using LeeDroid ROM. I have used the same trial on my Desire HD with no problems (also LeeDroid ROM).
Anyone have any ideas what might be the problem? No point buying the software if I can't get it to work...

That's interesting - it suggests the software is a bit flaky. I left it running whilst I went for a drive, and it did the same for about 40 minutes, and never got a full fix. Worked perfectly on the Desire though. Very strange. I won't be buying the full version at the moment that's for sure!

i got aura fully working on my DHD with fast gps fix
i have read some tips and tricks
install aura apk
reboot
download map
start aura and setup to your needs and likes
reboot
before using it to navigate, let it atleast fix once (stationary) completly
than you should have a fix almost directly(i have, even in my appartment)

Thanks I'll give it a try
BTW in my original post I should have said the trial works on my Desire, and not on the DHD. However, I have tried the above suggestion, and got the whole thing working. It's interesting that you can download the entire world in maps if you want, for a 7 day trial period. need to drive fast then!

I'm not happy with Sygic Aura at all.
First I really liked it and bought it but there are now 'bugs' introduced which renders this door to door gps software as useless.
Since ver2.1x you do not get arrival time (owww small bug according to the support team)
Last couple of weeks I noticed that in some big streets there is no way to insert a house number, euhm excuse me on a road that is about 10km long in the middle of Brussels, not so funny if you have professional contacts and you have to drive in that jungle staring at house numbers.
I just tried another couple of my other addresses and no house number, just unbelievable.
Tried my colleagues Navigon and tried iGO on my WinMo pda and house numbers everywhere, so software bug.
The support says that they are working on it and that it would just take weeks to solve the 'small bugs'.
At this moment I am so angry that I am going to claim my money back via paypal.

I can't even get it to run.
It was all ok for a while and then I flashed a new rom and it started force closing on me after I reinstalled it.
Can't really be bothered with it since the routing was gimp anyway.

I think Sygic have some work to do...
Latest version of Aura is still way to buggy for everyday use.
It has, in my opinion, the best looking UI of most (maybe all) SatNav apps for Android, but it has some serious flaws when it come to giving directions.
I have previously written a post on my views here:
http://forum.xda-developers.com/showthread.php?t=874988
Dazultra and I have also done a SatNav comparison:
http://forum.xda-developers.com/showthread.php?t=902264
Please have a look

I tried Aura on my DHD for some time. Did every tric I could find to get a stable GPS based position, but my location keeps jumping around or is lagging behind for sometimes 30 second.
Driving in the city this is unacceptable. I'm missing turns because Aura thinks I'm still 50-100 meters back.
I installed GPS Status and used it to force a cold boot for my GPS. Put it outside on my gardentable for 1 hour (10 min would have been more than sufficient, but I forgot all about it )
No improvement with jumpy and lagging position in Aura.
So now I removed Aura again and thats too bad. Sygic Aura is at this moment the nicest looking and most complete (incl. rather cheap traffic info) nav. system.
On the other hand, I would realy like IGOmyWay or IGO PRIMO on my DHD with full resolution. I threw out my WM (Touch HD) phone some weeks ago on which I had PRIMO including working TMC. That was fantastic, and fully configurable (sys.txt).
Let's see what the next months brings us.....

Sygic Aura on Desire HD
Hi everyone
I've just started using Aura on my Desire HD - impressed with the UI etc, but have a couple of niggles which people may be able to help with...
I've got the paid version 2.1, build R-20021, running on stock Desire HD, android 2.2
Changing voice - I've browsed the files using Astro and I have a female voice (amongst others)... how do i change the settings to use this voice file?
On my version, I can only turn on/off voice navigation, though i can change the different alert/warning sounds.
Re: speed camera/speed limit database... does anyone know how often this is updated? I'm based in UK and a local mainroad is indicating the incorrect speed limit (it changed from 60 -> 50 about 4years ago)...
Thanks in advance

Does someone recongnize the lagging behaviour of Aura as I describes 2 posts ago?

Me too. I drive with constant speed and the cursor freezes or de-accelerate then accelerates... then de-accelerate again... etc.. With navigon and Igo everything is fine! I have DHD with leddroid but It was the same with stock 1.72

I have exactly the same GPS-lagging problem with this program. Really odd though, as you would expect that the program gets the GPS info from android, just like any other navigation program (i.e. google maps).

GPS not working, Wi-Fi picky, Problem with music player

Hi guys!
At first I was surprised by the Defy after switching from a iPhone 3G. It's much faster, better camera and battery etc. Although don't get me started on syncing the Defy to a Mac...
Now I do have some problems that really give me headaches:
1. GPS not working
I think the GPS stopped working when I took the phone to the US (I'm from Germany). Which sucks because I wanted to use it for navigation. I Installed the GPS Test App, erased and refreshed the A-GPS Data. Doesn't help. I switched it on and off several times, went into Airplane mode and so on. Nothing.
GPS Test tells me that there are usually 1-4 satellites in view but non in use.
Any help here?
2. Wi-Fi won't connect sometimes
It feels like the Wi-Fi has worse reception that the iPhone anyway but it sometimes just won't connect. Might take 10 minutes until it suddenly does.
3. Music player
This is a minor problem but it's still really bugging me because I'm a big music buff. I have a couple mixtapes and compilations on the phone but I'm not able to play them as they're supposed to be, since the phone splits the Albums into several albums due to the Interpret-tag being different. It still does that after I edited the Album Interpret-tag.
I'm happy for any help. Right now I'm a little frustrated since with the iPhone everything has been so easy and, you know, just worked!

What rom are you in? Rooted?
Sent from my MB525 using XDA App

The regular motoblur that comes with the phone. I just updated to 2.2.2. and at least the GPS is working again. That's the most important thing.
Any recommendations for a slick looking music player that gets the tags right?

Ok, so GPS again not working anymore. Only finds one satellite and does not use it. I crossed the border from Canada to the US, could that have anything to do with it?

which rom have you flashed？
GPS with problem maybe your rom is broken.

As I said, it's the default ROM. Recently updated to 2.2.2, not rooted or anything.

You're using default froyo not rooted? Are you using tmobile usa? Have you check the settings-location and security, make sure gps and network are checked. What app are you using for gps, because some app turn gps on/off so you hane to check again.

Id3 issue on original update
The problem with id3 tags after update to official 2.2.2 is a known and annoying one. Sometimes a whole album is not recognised, but usually its just few songs from it, random track numbers.The bug is with Android's library, so it prevails in all the players that work with it... It goes to such extent that in some music players you look at the song-no tags, you select edit tags and all tags are properly shown in the editing window.Save and than boom, unknown artist, track again.
My solution: Use folders instead of library (powerAmp player or other)
As for gps, just today I stopped getting fix on satellites (after a month, so I hope it will come back)...

Android virgin questions :P

Hi there, i got desire HD with Android Revolution HD 7.0(2.3.5 (Gingerbread) + Sense UI 3.5 )
and i got some questions.
1. I have installed CurrentWidget in order to check on my battery and i set the log correctly but the application is not making any log ? Do i need to keep it running or its running by it self?
2.I got Samsung ue55d8000 TV and i connected it to my wireless AP(phone also connected to it) and Samsung Remote cant seem to find it?
ps. Connection works on TV and on phone.

ok i fixed the samsung problem, it was firmware upgrading to new got it working.
anyone for this current wig. ?

If you have any task killers exclude Cur. Widg. from it, and be sure to actually place the widget on the home screen.

Goto Curr.Wid from Settings-> apps. Clear the data and force close. then restart the application. probably this might work.

canabi 1859
ok i kinda fixed it dont know how
one some more questions coming
3. ok after cleaning my antenna contacts i get better gps reception i can fix on 7-9 sats. in like less then 30seconds, but when i keep start walking(was in park trees only 500m around me clear no buildnings) i start losing sats one by one.
i installed igo my way 8.4.3.179971 put maps on it and everything else i started it and i got fix on my location but when i started walking (same in park) it says gps lost and gps off.
So my question is this rom related problem or hardware or even application?
4. How can i force phone to install applications on Sd card?

The same with my device at first.
I used the rooted ICS 4.0.5 and GPS Status from the market and started some experiments.
There'd been no response from the GPS part at all.
After some time i used a serial port api tool to directly connect to ttyO0.
Though the GPS part uses some hex protocol i had been able to get a response from the chip, but it was not human readable.
So this way i made sure there's no hardware damage on my UART interface or GPS chipset.
Afterwards i did some hard resets and checked settings of the UART by typing:
Code:
stty -F /dev/ttyO0
I started to run GPS Status again and also deleted my AGPS data by using the tools menu. Then i changed GPS Status setup to stay active and prevent device from sleep.
I took a while, but then the first satellite came in sight, still no fix.
Next day i did the same after some time more and more satellite where seen, but still no fix.
I restarted my device again to boot stock firmware.
Same again... more and more satellites became visible... but then... suddenly a fix. In fact it took very very long and i'm not very satisfied with the situation.
After i re-booted to rooted firmware again i was able to get a fix here as well.
The signal reception is still far from being nice though.
Try to get a fix with stock firmware first, then reboot and check again with rooted firmware.

Should be no problem with this setup.

Nice thread, but people start to mix things up at some point.
Though the GPS and location service on Android OS is quite mystic, i'll try to concentrate on some facts.
Hardware:
- NL5550 chipset used on Archos Gen9 is up to date and not that bad
(merged into WL1283 chipset, see http://www.murata-ws.com/com7.htm)
- Due to hugh shielding areas, GPS reception is not the best with tablets (if compared to handsets).
- GPS antenna and position of the antenna seems to be problematic
Software:
- Firmware setup changed form HC to ICS
- size of the patch file for the chip had grown in ICS
(mabye they wanted to make thinks better, but they got worse)
So what could be done...
Hardware:
- I started searching for a better antenna to be placed in the housing
(e.g. helical/helix antenna)
- Place a HF-connector on the mainboard to use an external antenna
Software:
- Extract the firmware files from HC and try this setup for ICS
- try to find other devices based on the navilink chipset and compare their firmware setup
Basically GPS works on ICS and things in fact are not related to ICS itself.
Some firmware tweaks might be the cause of these issues.
The basic construcion of the hardware could have some side-effects on this as well.
Some people seem to have no trouble at all, so at least GPS reception is of course little bit depended on the weather and the area you live in.
I may post the HC firmware files here, if you like to try the HC setup on your device.

GPS lib loops
Hi,
I can ONLY get my GPS to lock on if the wifi and location services are enabled and working.
This is because, the gpslib tries to speed up the lock and position information by going out on the internet and firstly fetch the time from the main European ntp server.
Looking at the system logs, it appears to get into an infinite loop waiting for a time update.
Therefore my gps WILL NEVER WORK if actuated with NO wifi.
However..... If I start the GPS application, (I am using mmaps) with the wifi on and the locaation services on I get a good lock, with 10-12 satellites with the Archos INSIDE my house, within a few minutes. (There is nothing wrong with the sensitivity of the GPS engine!)
If I then stop the app and turn off the Wifi and location serves and restart the app it will get a lock in a few seconds and stay working until I power down the Archos.
This is OK apart from the problem that I want to use the Archos in my car with no wifi.
cheers

Yes, thanks for pointing at this.
Try to disable automatic time sync in time & date settings menu and check again.
You should definitely get a fix without setting the other location services or having wifi enabled all the time.

seems like a complicated science for a simple functionality
my older external sirf 3 receiver need only 5 minutes for sat fix after cold start (very cloudy!) and 10 up to 15 seconds in warm state. i wonder why the archos is much slower.

Assisted GPS !!!!!
Hi,
Unfortunately The Archos uses assisted GPS
I am not allowed to post links yet so see:- the wikipedia entry for assisted GPS
The Archos "might" use the Qualcomm chipset "GPSONE" , I am not sure but a lot of phone makers use it:-
see the wikipedia entry for GPSONE
Like I said in a previous post in the other place, I wish Android tablets were not still so mobile phone centric.

Archos uses TI NaviLink chipset. GPSONE is Qualcomm only and there's no Qualcomm chip inside our units.
TI NaviLink supports AGPS as well but it does not rely on that.
In other words even without assisted data you'll get a fix... sooner or later
Assisted GPS is always an option to get faster fix.
Did you try again with disabled automatic network time setting?

libgps loops!
Hi Scholbert
Thanks for correction re type of gps chip. Why I thought there was a GPSONE chip in the Archos was because the /etc/gps.conf uses the Qualcomm extra server site , see below.
However I still maintain there is an infinite loop in the ICS (or Archos modded) libgps. I have left the machine on for 8 hours and never got a lock without wifi.
I cannot post the /etc/gps.conf and the log here because I am too noob yet.
Instead have a look at my post here:-

I guess you're right... I made some further tests and must confirm, that i observed the same behaviour. This in fact is really annoying...
The GPS receiver receives satellite information (satellites can be "seen"), but there's no fix without beeing connected to the networks.
This is acceptable. We should contact the Archos developer's, especially user courville who has joined this forum for bug fixing.
He's an employee of Archos and one of the chief developer's, very friendly and helpful as well!

Had a view at this thread and read your posting.
If the described behaviour is compiled in the lib, we can't fix it ourselfs.
Archos needs to fix this problem by tweaking the library.
If it is related to a setup option, we might easily fix it at least on a rooted device using a customized image.
Had anyone tried the 4.0.6. firmware test release yet... maybe GPS got fixed as well.

Since GPS is integrated into wlan chip it may be necessary to power on wifi to power on also GPS part.

On 4.0.6 GPS works exactly the same.
Some observations (GPS Test)
-it takes quite a while to aquire lock even with "fresh" aGPS data
-lock is not stable- it likes to dissapear even if I don't move tablet
-catching new sattelites "unlocks" the lock
-accuracy seems poor- GPS Test didn't report anything less than 80 meters (Xperia Arc S in the same spot has <20m)

I get a lock within 10 seconds with my G9 inside my house. The accuracy has gotten down to under 4 meters. On my particular tablet, it works fantastic. I never had to clear AGPS data. I think this is luck of the draw. Some work great, some not.
My ASUS TF101 has all the issues you guys describe. Unreliable and slow. Most people with the TF101 do not have my issue.
My wife's LG Optimus One GPS works great, locks in under 20 seconds and never unlocks. My Samsung Galaxy Ace struggles to get a lock but can maintain it once lock is achieved.
All these devices are running different Android versions so I agree that it is not a software issue. I tend to believe it is the fact some get better build quality antennas than others making some of the same devices work better than their twins.

i have tested copilot on 3 different archos G9 80s. All have gotten a lock in my house. I have tested one while driving to work and it maintains the lock.

anybody want an archos 101g9 ?????
hi,
i'm back here after testing my 101 and i'm not really lucky
thanks to all here first. i pursued the discussion with interest.
my archos did not work with gps at all!. i checked with gpstest and gps status apps indoor and outdoor several hours/days. no satellites found! nothing, zeroooooooooooo. clear sky, no clouds and NO satellites. i'm alone in the universe
what i did:
- device cold start (many times)
- switching on/off date and time from ntp server
- wifi on/off
- google location service on/off
no idea what happen. this is not my first archos. my older g8 had broken usb ports and was changed 2 times. the g9 freezes very often in cpu state "hotplug", run stable only with half speed and gps don't work. why gps need an internet connection?? i have no 3g stick in my tablet and no wifi in my car. yes, i can connect my phone with wifi tethering but sorry, that's not what i have planned. puuh archos, what do you think what customers tolerate. i love android, but the next tablet should be better an ipad
seems, there is a defect. how can i check my hardware before i put it in the trash?
thanks,
4carlos
by the way, my htc legend with froyo works great. it beams my to every point i wish!

Sorry to hear all you guys are having such problems with gps lock.
I have an original 8gb 9g classic. I have taken it through Honeycomb and up to the last ICS update. I have rooted it, over-clocked it and it has taken everything that I have thrown at it!
In every case, the gps has been first class. Using gpsstatus from the market, it locks on to 9 sats from inside my house within 30 seconds.
It was originally set to europe.pool in the gps.cfg file and I got a good lock with that. When I changed to rooted custom fw, I downloaded fasterfix from the market and used it to change the gps.cfg to uk.pool. This speeded up the lock and increased the number of sats to 11.
One thing that may help, has anyone tried toggling airplane mode on then off again. Whenever I install a new rom, on phone or tablet, I reboot the system at
least twice after setup and then toggle airplane on/off. This was an instruction in some roms that had wifi issues and I now do it as a matter of course.
It may be worth a try.
I use Co pilot live as satnav and it has never failed to lock on within seconds of being set up.

GPS on G9 still behaves strange...
First of all, thanks for posting your observations.
The GPS issue remains little mystic though

I just got a fix within a minute, yesterday it was a no go!
The device actually needed a reboot before. What is responsible for this locking???
I got the fix by...
- deleting the AGPS data in the settings menu of GPStool
- setting the data update interval to never
- unchecked set system time from server in the device settings
- Wifi and 3G were disabled as well
So it's possible to get satelite fix without network connection.
But something may lock the interface. Afterwards it seems to be impossible to get a fix again... at least things get worse.
BTW, GPStool and the AGPS "framework" of the G9 use definitely different data bases for the assisted data. Maybe this causes locks as well...
So from what i can tell... disabling the AGPS function in GPStool definitely helped to get a fix.

O.k. might try fasterfix... though it seems to set the timeserver to another domain... What else does it do?
We need more understanding of the mechanism in general.
Did anyone try the Gingerbread setup on ICS yet?
I may post the files here...

Maybe it's worth a try but maybe it won't help anything.
As far as i can tell, a reboot certainly fixes some kind of lock on the interface.
But as long as we always guess there will be no improvement, nor we'll find the real reason for the missbehaviour.

I can't find GPStool in the market - is that the correct name?
I would like to try your procedure to find out if my GPS is working at all.
Thx.
Don.

i guess :
GPS Status & Toolbox (author EclipSim, can delete agps data)
also nice
GPS Test (author Chartcross Limited)
GPS Status (author espresso3389, nice graphical tool but only portrait mode)
btw.
upgrade to firmware 4.06 (fix for increasing gps stability) did not help in my case. only my problem has more stability now. still no satellites in sight. my htc legend shows a minimum of 5 satellites with the tools from above at my location (indoor) but still nothing with my archos. disappointing.
the better way is to check the gps functionality before rooting the tablet (loosing guarantee!). seems a weak point of tablet.
i'm searching for an external bt mouse. any recommendation? the mouse should be bought in germany.
