Does anyone also notice that the S10 drops the GPS fix for several seconds when passing a loop on the highway (german Autobahn has many of them)?
When I'm in the middle of the loop the fix drops and google maps navigation freezes and then jumps around in the map for about a minute. This is a serious problem when you need to know the path in an unknown region. I tracked this with several gps tools from playstore, they all show that the fix drops from minimum 10 to 25 satellites to 0 immediatly.
I already tried to delete A-GPS data and refresh them and recalibrated the compass, but that didnt help.
Any solution or workaround?
I think you are going way to fast on the Autobahn. The gps cant catch up with your car
Yes, you need to slow down. GPS satellites travel at approximately 14,000 km/hr so you're out running them. ? I'm not sure there is a fix because I imagine those coils have a magnetic field. Maybe try making a little tinfoil hat for the phone which would probably also block the GPS.

as per subject what is the reasonable time for gps fix? can installed applications effect gps fix? what about clouds? could it be hard to get fix in cloudy whether?
Don't know whats normal but sitting in my house with TT I get 3-4 bars in about 5 seconds once I open TT. This is on the kaiser not the fugly

goto www.gpspassion.com and you'll find a wealth of gps info. Reasonable time with quick gps is about 5-20 seconds with a good signal (outside) on the kaiser. Clouds can affect things but I've never seen it hamper anything.
I wonder if there is a difference in aquiring signal between the Kaiser and tilt? I have not seen much issue on the kaiser but there are alot on the tilt on several boards?

my kaiser takes very long at the moment
It can take up to a minute or so if you haven't used it in a while. Sometimes it pretty quick (like <15 seconds, esp when it has been used in past hour or so).
I used the GPS today for a road trip. . . fired up QuickGPS and then launched my mapping software. It only took about 10 seconds for the software to "find" the onboard GPS -- and this was the first time I had used it in the 24 hours I've had it.
You need to use QuickGPS first.
I have had GPS receivers previously as well as used some, both normal consumer as well as aviation grade GPS systems. Now I have the Kaiser/TyTN II and I am impressed with how sensitive it is! For not losing signal or dropping position I am amazed, good stuff!
BUT ... since it uses so much battery when the GPS is running, I sometimes turn it of for a while, then on later on again. Especially when moving a lot while being turned off (flying or driving), turning it back on can sometimes give problems getting a new fix! Sometimes it gets a fix quickly, but it is hundreds or thousands of miles off. I know it is complicated 3D math for a GPS to aquire its position, and I know it is possible to get a false lock, but the GPS receivers I have tried and had previously never accepted a bad fix.
The unit knows where the satellites are supposed to be, given the time and approximate position, so that is what it assumes. But when it has been off, and then on again and only moved some hundred miles, it can get this false position fix that it cannot get out of easily. If I turn it off again and wait until none of the previous satellites are in view (flying for another hour for instance), it finally realizes it has to start over with a new fix. Older GPS units I used/had often had an option of making a cold start fix (search the sky, autosearch or other names for basically the same thing). It is also sometimes possible to specify or change the last "known" position of the GPS to make it easier for it to get a new fix again. The latter requires that you either can find your rough position in a map or you know a rough lat/lon position.
So, two questions:
1) How do I break a bad fix, tell the unit it is on a wrong path - do a renewed search the sky?
2) How can I change the "previous GPS position" so the GPS unit is forced to assume another position?
I have some GPS applications where you can change the last know position, but it only seems to stay in the program, it is not fed back into the GPS receiver.
No comments here? Must be others with the same problem. Even the oldest, most basic GPS units had an option to enter position manually, or to enforce a new search from scratch. There must at least be some kind of reset function! (NOT hard reset, thanks!)

I tried google maps and discovered that my actual position was off by some 50 meters from where I actually was. Then I also discovered that in the area I was, if you superimposed the roads on top of the satellite image in Google maps, it was also set off, by about 10 meters only.
Ever since I tried Google maps, my GPS fixes correctly and updates data all the time, but with some programs speed remains 0 and direction remains north even if I move around. After re-flashing the original rom everything is back to normal. Do you know why this happened?
I have got the same problem.
Once after using TrackMe and once after getting my position in Virtual Earth Mobile.
Both times i have used the gps only for a short while and then closed it. On the next start the position has been several hundreds of kilometers off and the speed shows several hundreds kph although I stand still.
Both times the gps has not been ok until the next day.
I have tried to soft reset and also updated the Quick GPS with no result.
I found this thread Kaiser GPS positioning problems which looks a lot like the same.
I have been using the GPS a lot more frequently recently and at first I thought it was these two apps, but now it seem more general. Before I used TomTom on a few occasions with no problem, but then the GPS was on for a longer period.
Anyone else?
Well i have a question.
When i use TomTom or IGO the position on the screen is always about 50 meters off to where I actually am.
So since IGO & TomTom Both have the same behaviour i guess i should look at the GPS module.
My old S730 was always spot on... when i looked at the screen and saw a turn on the left, there actually was a turn to the left.
Anybody knows how this can be solved ?
My TD2 does not have this problem, perhaps there is an issue with your particular phone?
I thoght about it before and found out that it was not inaccuracy but the delay GPS chip needs to calculate your position. Do one test. Some time when you stop at a red light and you know you've waited for about 5 secs, check your position then. I believe it will be accurate then.
I noticed that some GPS's try to calculate your current position based on direction and speed you had few seconds ago. I found out about it one time when I waited at the red light in a long tunnel. Obviously there was no signal there, but when I stopped, GPS kept on showing that I was moving about 40MPH for several seconds before it finally showed lost signal message.
Some GPS's do calculate your position ahead of time and some don't.
Maybe it was because i had assisted GPS turned on...
If you do a search on AGPS LAG (ANY HTCPRODUCT WITH AGPS) then you will see enough posts that speciffically deals with this problem...
My old phone is SPOT ON with TT and my new 2 times faster phone is less accurate, and in a street with lots of turns, take a-lefts etc it's quite important to rely on the machine. And when the machine says turn left on the next corner, is that left the one i am currently at or the one 20 meters ahead from where i am now....
It should be just as with my old phone spot on
Well disabeling AGPS definitely works...
I am now about 20 meters behind all the time. This seems acceptable although I keep finding it strange that my older phone was way more accurate.....
you mean disable QuickGPS or disable AGPS in Advanced Config??
It is definitely a lag issue, not a precision issue: my TD2 internal GPS is at least as accurate as my Qstarz bluetooth GPS logger, and this one has a dedicated large antenna and good GPS chipset. TD2 sensitivity is also comparable, maybe even better inside building, and the time before locking a signal from coldstart is also comparable or better...
BUT there is a lag of maybe 30 m around 50 km/h in my car, and it is is indeed quite noticeable for driving directions...No big deal for me, as I do not rely on voice instruction but always have a quick peak at the screen (I was bitten by ambiguous instruction often enough in the past with other GPS system to have developped this quick peak habit ;-) )..but this lag is indeed anoying...
I'd like to try the TD2 using the external GPS through bluetooth, if I find time to do it this WE I will post my conclusions...

I use to have the same problem as you, so, I've tried the tweak referred in this post http://forum.xda-developers.com/showthread.php?t=514912 and it did the trick for me.
I use iGo8 and NDrive and the accuracy improved a lot, it's almost spot on, no matter what speed I'm driving.
Regards,
I was in my mates Audi TT the other day. He has the built in GPS in the dash board. I noticed there was as much lag as you see on an HTC device.
Also was in a car a few months asgo with someone who had a stand alone TomTom device and that too had lag.
Unless you're paying thousands of Dollars for millitary grade navigation equipment, i wouldn't spare the lag issue another thought.
Not long now ...
There's a bigger lag comming if the media are to be believed (and based on everything that comes from the tele, radio and newspapers these days - there're probably not - they can't even get the weather right)

"

Diamond1 paid £150 was spot on. No Lag. The speed indicator on tomtom was very accurate, not like on the diamond2 where it takes over 2 seconds to show a speed change. I am surprised that not many people have noticed the slow and inaccurate GPS performance of the D2.
Hello all,
After 2 week I bought my G800H, the GPS star to take too long to get GPS Signal. Some times more than 10 minutes
Even with 3G (H+) working well and the configuration in "High accuracy".
Other thing that happens is the GPS notification keeps blinking even when no app running.
Anyone with the same problem?
Thanks and B.R.
I have the same problem. Didnt find any solutions yet. Reboot, apps, settings. For me i could be the OS or the sensor. I have a S3 Mini and the gps signal works as a beauty!!!!

Happened to me also few times, but it happens only when I try to use GPS in car. Outside it works without any problems and gets lock within a minute.
Sometimes in car it gets lock and then looses it after few seconds and has to reacquire it again, which takes few minutes.
Maybe there is some interference?
i've similar issue with my sm-g800 f with 3g connection disabled (ten minutes to fix), when i enable connectionless tha n 1 minute.
I my case problem is wrong server in gps conf file (north america server), but i'am in europe. I dont' know any method without root device to fix it
(changing server with right one, and reset agps data with gps test is the ony way to fix i know)
I have narrowed down my problem to Sygic BlackBox.
If I disable this addon, GPS works correctly and is able to fix quickly. When enabled, I experience poor quality of signal for the first 10-15 minutes, even with data enabled.
Create an issue with sygic, hopefully they will have some tips for me
Today I was experiencing GPS issues again but unfortunately it was not related to sygic.
I have searched around internet a found a bunch of people complaining about GPS signal on S5 mini (both single and dual sim).
Reset of AGPS data and restart helped, but that's not really useful.
Anyone else here experiencing weak GPS signal? I will try to ping Samsung support on Monday...
Here the same problem. G800h mini on my s5. poor gps fix and very inaccurate. I flashed to firmware G800HXXU1ANK2_G800HXEO1ANL1_G800HXXU1ANK2_HOME.
Anyone a solution?

Hi! Same problem on my S5 mini duos using MAPS ou WAZE. Any news about a solution?
It seems to be fixed for me, at least last 3 days I didn't have problems and I was able to navigate with sygic without any issues (2x 150km trips).
I tried GPS Status application and that was not able to get signal also, so I have tried to do factory reset, whether this is software related problem, but that did not help either.
So I though it might be some issue with antenna and connection to motherboard. But S5 mini does not have any bolts or anything like that, everything holds together by strong adhesive.
So I decided to heat the back side around GPS antenna (left upper corner if you are looking at the back of cell phone) with hair drier and push it hard inside when it was warm.
After that I have tried GPS Status application and it locked in 21 seconds and was able to lock on 15 satellites (Before I didn't get more then one or two satellite after 15 minutes even with data enabled).
Don't know if it will help anyone else, but might be worth a try.
that sounds interesting.
Guys, any news ou resolution about this issue? I bought mine few weeks ago and the GPS is the worst i' ever had! I can't use WAZE ou GMAPS properly because of this!!! First time this is happening to me....

i could fix my wifes s5 mini too with the hairdryer, thx for the idea :good:
1. remove backcover, lay it flat on a towel (face down)
2. heaten up the upper left corner (backside) as described above,
3. then push it hard down for about 5 minutes til cooldown to be sure it is fixed in position
4. profit
:laugh:
edit: before the procedure the phone received 4 to 5 weak satellites in gps test, now the phone receive 16 satellites after 10 seconds.
Glad to hear it helped to someone else also.
I know it sounds stupid but works
@dawaldi Please can you portray a picture of it?
Gesendet von meinem SM-G800H mit Tapatalk
Here is picture of the phone with the back cover opened up, there are some kind of springs and glue inside the "doors"
Personally I have pushed down both side, just to be sure.
thank you! Today I had tested on my phone. Heated with a hair dryer and then the finger pressure on the body. It is better but the pressure is not sufficient permanent.
I will test tomorrow.

Oh my god! I live in Brazil and I hve been strugling to find a solution to my GPS issue for 3months . It worked In the third attempt of pressing it down after hairdrying it!! Now it gets locked within 3 seconds inside my house! !! Thanks guys!! Im so happy!!! No I can go to short hikes and travel with it again!
CHEERS MATES!!
after 20h n back to the begining
Bad news. After 20h my gps came back to where it was.... i tried the hair dryer again a few times but with no success..... i believe i have to send it to repair
Best of luck for you guys....
Well, it worked for me ate least for 3 days... After, the same problem.how about u guys?!

Here too!
I have a strange problem with my Z3C's GPS (note: running CM12.1 nightlies). The problem did not occur when I used the phone for navigation last year, I first noticed it some time in January. So either my hardware has broken since last year or some upgrade broke my GPS.
Symptom: GPS does not work reliably when stationary or moving at slow speed (i.e. hiking or running). It takes forever to get a fix. Literally, many times I can put the device down outside with completely free view to the sky and after 15 minutes and more there is still no fix. The number of satellites picked up according to GPS Status&Monitor varies, most of the time 0 to 2, sometimes up to 8, then dropping again to 0 for no obvious reason, but even with 8 satellites no location?!? If I get a fix and record a track with OruxMaps, the quality is bad, many dropouts, very often the fix is lost. The GPS location and heading is drifting around when I'm standing stationary.
However, when I drive in car and use Here Maps or OruxMaps, the GPS is perfectly usable: Fix after about 30 secs in motion, good positioning quality, good tracks. Even when the car is standing, the position is not drifting. As soon as I leave the car and walk around, the positioning is soon degrading.
An issue with might be connected is that I cannot calibrate my compass: Every compass app claims that it has to be calibrated (even if the compass bearing itself seems to be pretty OK - every direction is where it is supposed to be). All the methods given on the net - waving 8, turning in all three axes - never got me the compass calibrated. I also refreshed AGPS, cleared caches and dalvik, regularly flash an upgraded CM nightly, no change.
As I'm using CM12.1, I cannot get into services menus, it seams.
Has anybody an idea what could be the reason for this strange behaviour?
