[Q] My GPS works better in Great Britain than Germany? - Galaxy S III Mini Q&A, Help & Troubleshooting

Hi,
I just noticed a curious thing, I can't explain - my GPS seems to work better the farther West I get. I live in Germany (Frankfurt) and went on vacation to London (about 400 Miles west from Frankfurt). There I started noticing that my Galaxy S3 was much faster in fixing my position than I was used to. So I decided to start an experiment - since I was going back by train I started a GPS recording when boarding in London and monitored how the signal quality behaved (To show you how bad my GPS usualy is: I was not once able to get a GPS fix inside a train or bus in Frankfurt - in London it worked almost instantly). As it turns out - the overall signal got weaker and weaker during the journey. Just before Brussels my Phone started to lose the position fix for a few moments, than it happend more frequently, accuracy and number of satellites "in use" went down and just after Cologne the fix was completely lost and I wasn't able to get one inside the train until my destination.
During the journey I switched trains only once in Brussels and the weather was sunny for the whole time - so that should be no reason for the worsening signal.
Does anybody have an explanation for this behaviour? And maybe a way to fix it?
I'm using a Samsung Galaxy S3 Mini with Cyanogenmod (CM 11-20141112-SNAPSHOT-M12-serranoltexx) and had it set to "GPS only"

Anyone have a fix for the Quick GPS problem?

I have tried modifying the registry to the values that should fix it but it does not fix it for me. I still do not get an update. Any ideas?
Thanks,
Dan
I ended up hard resetting my device, I'm sorry to say. When I first got my phone, I ran QuickGPS and it downloaded some data. Ever since then, QuickGPS would not work and neither would my GPS. I tried everything I could find, including *gasp* going into the External GPS settings.
After hard resetting, I will not run QuickGPS again. All I did was fire up Windows Live Search and let it find the satellites. It only took a couple of minutes and I was up and running.
That was 3 days ago and my GPS is still working. Any GPS capable app I run takes less than 30 seconds to get a fix, even inside my house. I have not run QuickGPS since then and I don't intend to.

How can it work inside your house? I do not think that is even possible. Satellite receivers are line of sight. Try putting a direct TV dish in your house and see what kind of reception you get.

Yea I was doubting that too. GPS doesn't work in my house, as soon as I step outside, boom, its on.
It works indoors at my place. Its not line of sight, otherwise even the phone case would be blocking the receiver. However it works much better outdoors. I think the reason is the radio signal from the satellites is very weak and doesn't penetrate obstacles very well.
I have a few windows in my house and I get enough of a signal (usually only 3 or so birds) to track my location. It's good enough to get an initial fix.
.:Christian:.
sad to hear that it doesnt work for some people.
ive used it from the beginning and it works fine. no problems up to now.
"thats not even possible"
cmon... i was surprised, too. but it works in my room (under the roof)
quality is weak (1-2 satellites) but it can get your position.
of course radio or gsm both have more sending strength but they also work in your house, dont they?
hi, hmm.. i have got no problems with GPS at all and to be precize i was really suprised with the speed lock. i instaled tomtom fired it up and then set it up with other NMEA GPS receiver and my device found the signal in 5 seconds !!! and i got 5 satelites in range ...aha im in my house ..maybe cos i am a student and the glazing is single

How bad the GPS problem is?

Lets see if I understand this correctly....
on the samsung galaxy s GPS system, there are 2 options:
1)Use wireless networks: Set the device to use the
wireless networking to indicate your location
2)Use GPS satellites : Enable the GPS receiver to indicate your location
For now, we know that using the option 2 gives us crappy results (loosing signals, cannot lock sattelites, jumping around etc)
Now, for option 1: choosing option 1 means that launching the maps application should indicate where your location is currently by using some kind of triangulation method based on the availability of GSM signal, so it should even work when you are indoor or whenever there is a GSM signal......
But apparently on this phone, it only shows your initial location, then after that even if you have moved 1 km from your initial location, the location indicator arrow is stuck at your initial location, meaning that it doesnt track you and your movement, which means both options simply dont work on this phone....
On my wife's iphone, the GPS functionality works wonderfully even when i am inside a building and it keeps updating your location as you move continuosly.
It just shows you how careless and hasty samsung is in launching this product that even the simplest form of GPS functionality, one that is based on GSM triangulation method, also doesnt work..... and they still went ahead with the launch.....
Absolutely no problems with GSM or GPS positioning now that I'm using I9000XWJG5. Locks on satellites within 22 seconds from switch on. Thats at 30m precision. After 10 seconds more gets to 5m precision.
This is from inside my building. (Using GPS Status to check)
Same here. Your wife's phone probably also uses the mobile network to keep location inside buildings, or wireless networks. Try enabling skyhook, that is all i did.
used skyhook, and assited mode, accuracy set to 50, changed supl/cp settings, but compared to my g1 or hd2 or e61 or 10 year old bt/gps mouse the gps quality is just rubbish. (XXJF3)
no problem even without skyhook, but using skyhook gets locking much faster
i'm comparing it to my old HTC Athena, which takes sometimes over 5min to lock to 1 satellite in the great white open sky.... sigh...
sometimes it wont even lock if the weather is poor, takes like 30min or more to lock, under those conditions.
simply insane.
so SGS i9000 is like a dream to use.
g1 / hd2 / e61 only take seconds to get a full lock with accuracy about 3m. in my opinion skyhook and gps plus are needless if you have a working cb a-gps.
From my experience its the rom. As my gps worked fine with default FE3 (optus au) rom even indoors but when i flashed G5 (latest euro) i could only lock onto one sat outdoors even with skyhooks setting. Then i installed Samset 1.2 update.zip the gps works again, thats just my 2cents

For the record I haven't had any issues with GPS other than it being fair slower than my Milestone.
Didn't you sell your Galaxy S anyway?

Hey mate, I think I've seen you around the WP forums.
Quick question for you - I have a Milestone and am currently contemplating throwing it on eBay and grabbing the Galaxy S. Is there anything you miss from the Milestone?

The same here. The problems start when I go out and start to drive around in my car. My GPS is absolutely useless when you move around outdoors, but locks in a few seconds indoors.

Let me see if I understand this correctly. You have sold your SGS and you are still coming back here to crap on about the GPS and other small things which are only occurring on some people's phones and not others?
For the record, everything on my phone has been running silky smooth since day one. Lag only occurs with too many apps open and this is to be expected from an operating system that can multitask.

I sold my phone at a profit because currently i cannot afford to have unreliable phone in doing my job... then i searched for something better and can't find any.... so i'm still following the forum to see of all the problems i experience have been fixed .... if thats the case, i might buy another one....
and for the record, i didnt crap about the GPS, i'm just investigating it deeper, becase GPS is important for me...
Thats crap for you

Galaxy Tab GPS Not Working

I just got the T-Mobile Galaxy tab, and for some reason the GPS is not working at all... It shows the gps sign on the notification bar, but in maps, gps test, and gps status, there is no GPS data!
PLEASE HELP!
Thank you so much in advance,
Michael
i noticed that GPS perf is average indoor, if not below average. it is comparable to HTC Touch Pro, which is quite disappointing.
If you are trying from indoor, try to take it outside. many apps are saying that GPS works better when used with clear sky and i think it performs much better outside.

I would make sure that I'm not using a case that has a magnet or any kind of metal on it. They interfere with radios and especially the GPS.
A couple of months ago I started using a Zenus case which has magnetic buttons. Almost immediately my GPS stopped working. It took me a very long time to figure out the real culprit. I tried rooting, changing some gps related files etc. None worked until one day when after accidentally leaving the cover at home I switched on the GPS - it started working.
Dude, you should update the maps in your galaxy tab. I updated already my maps and gps is runing smooth.

I bought a tab last week in Germany. The gps work fine in Germany, Holland and Belgium. But right now I am in Turkey and here it just keeps "searching" but never gets a location.
I wonder why and what, but I suspect location has something to do with it.

hello i have a samsung galaxy tab (sprint) i live in malaysia,but when i on the gps it detect my location at hawaii plizz help me!!!
GPS not working
Hi
You definitely need to be outdoor for GPS receiver to obtain signal.
If indoors, you'll get signal if you have tile roof, not steel or concrete.
With a-gps, it might look like you are getting signal but actually, your device is using data to obtain location from cellular towers.
For best and quickest reception, enable your device's location and a-gps. Note, a-gps does not use lot of data, very little.

Question on the quality of the GPS

So I used my Droid 4 for the 1st time today for navigation. I had to go to Downtown Minneapolis and I use Google Navigation. A few times ,in Downtown, I lost the GPS signal and therefore took a wrong turn. How has navigation with Google Maps been working for everybody?

I haven't had any issues with the GPS. You can always improve performance by enabling Google location and WiFi. GPS often works poorly in cities due to poor visibility (tall buildings, etc). Wifi-location helps a lot. I remember my old iPod touch did an amazing job locating me on Wifi alone (in NYC).

I had Google location enabled. What is the GPS chipset on the Droid 4? I don't remember having had problems with Google Navigation on the Galaxy Nexus in Chicago. I believe the Nexus has a Sirf 3 chipset.
Got my d4 yesterday, GPS seemed to lock on quickly and work well for me -- just as good as my d1 if not better/faster.

I haven't used mine in downtown Minneapolis, but I use it in south Minneapolis and the suburbs a lot with very few issues. Sometimes if I hit a fork in the road it'll read me on the wrong fork for the first stretch until the forks are separated enough to read the difference, that's the only hiccup I've had.

The GPS locks on quickly indeed, but navigation is definitely a weak point in my opinion. There seems to be a lag of about 2-3 seconds where the GPS icon on the map is trying to catch up to your true position when driving in the car (similar to the Touch Pro 2 I believe). Also, even when driving in suburban areas (no tall buildings), the GPS stutters where it needs to relock onto your position. Kinda sad since I absolutely love everything else about the phone. I have until Monday to decide whether to keep it. I really don't want to go back to the Nexus with its crappy radio. Has anybody tried out GPS navigation (not just simple GPS lock) on the leaked ICS ROM?

Huawei P9 Plus GPS Quality

Hello everybody,
i would like to get some estimations regarding the quality of the GPS.
Please on the hardware- and the software end.
Last years i used a samsung I9300 and the GPS was fine.
Then i switched to an Elephone P9000. I think from the hardware end GPS was fine, but
it didn't work very well, maybe due to bad software? And it seems to be a common mediatek problem?
I didn't find anything in the internet, what do you think, does the GPS in p9 plus work well?
THX a lot,
Henning
As per my experience my P9 Plus has one of the best GPS I've ever experienced and it even works in the airplane pretty much accurately when comparing to airplane instruments. I'm based in SE Asia and have reception of American, Russian and few Chinese satellites and fix is pretty fast. No complaints here whatsoever.
Yes. GPS is great...
Hi,
in the meantime i also bought this phone.
I can confirm now that the GPS is very good.
It is even possible to see the two tracks on the road next by next if you drive
to a destination and come back the same way.
Also, had never this accurate GPS before...

Henning
Model number?
Great to hear that you all have a good gps signal. I just bought the p9 plus too. But strangely the gps signal seems like "not so good" , in my opinion. The story has to begin with my previous Huawei's phone.
I had previously owned the mate 7, which it was came with KitKat version and the GPS worked flawlessly. I updated it to lollipop then and the GPS still work perfectly, once turn on the gps, it takes only seconds (yes, it's really seconds, less than 5 seconds to be more appropriate...) to locate where I am. Those day I enjoyed using the gps as it was super fast and accurate. But things changed after I updated it to marshmallow recently. It became very unstable, very inaccurate. So I install the app "GPS test" and found that the accuracy is upto 150 feets which is very inaccurate (I can assure that the accuracy on KitKat and lollipop were only few feets or the most 10 plus feets, It was really super fast and accurate previously....). I know that weather, such as cloudy situation will affect the accuracy, numbers of satellites working etc so I tried to find out if that's the case but nope, I compared it with my cheap Elephone gps and under the same time same condition, I open the app and tested the gps, Elephone gave me the accuracy of 12 feets !
Sometimes when I try to use maps, it even can't detect where I am and if it does, it shows a wrong location. So I thought it is the problem of marshmallow as I searched on other forum and discovered that people also facing gps issue on Nexus phone with marshmallow version. I tried fixing it with another app "gps status & toolbox" , and also found out that "use wifi to improve accuracy" had to be turned on but the accuracy still only about 50 plus feets.
Then I bought the p9 plus, and hope that everything shall be very good just like the mate 7 KitKat and lollipop version, but it is not! The accuracy is also 50 plus feets after doing all the improvement work as above. So dear fellows I would like to ask what is your version of marshmallow and what is the accuracy of your p9 plus? Mine is VIE-L29C20B100. I am thinking if my version is not updated to the latest? And if there is a latest version , does the gps work good?
Hey guys!
I´m not really pleased with the performance of the GPS on my P9 plus ... but the app itself could be to blame. I was traveling on the highway and the navigation got confused and thought i´m traveling on the road parallel to the highway (surely minimum 100m distance between them). I´m using OSMand+ for navigation and it worked fine with other phones so far. Which app are you using?
I use Google maps, it works great imho, I came from a Galaxy S5
Try to create a new user profile on the phone. Switch to the new user and check if the GPS still behaves as you mentioned.
Hi all,
just to give some updates on my findings. Recently I went through a youtube video comparing mate 9 and p 9 plus (https://www.youtube.com/watch?v=_0impUegGO0&t=2s), at time 10:32 it showed exactly the GPS app that I use to test the GPS signal and it also showed exactly the same results as my p9 plus. This being said, I believe there is no way we can further improve the GPS accuracy and I suspect it is due to mashmallow problem (as I had said KitKat and lollipop run very well in accuracy and Nexus user with mashmallow also complain their GPS accuracy is not good), not because phone GPS not good. So maybe we will have to wait till Huawei release firmware update for android Nougat and see if it improves the GPS accuracy.
However, having said that, I didn't really find the GPS signal "not good" in real life. I mean, when u use the GPS app test the GPS it gives "not good" accuracy, but when I open the map for navigation, what I experience so far is EXTRAORDINARY GOOD. I turn on the GPS and immediately switch on the map app, it instantly locate where I am, not even trying to "looking for GPS signal", really really fast, really instantly locate where I am. And it is super accurate. So I think maybe the GPS app is not something that we should use to gauge whether the phone GPS quality good or not, the real life performance will tell more truth. Just like Antutu does not always really reflect the real performance of the phone.
So for those who are having GPS problems when using map, I will suggest u all try to use another map app, maybe the problems really came from the map itself but not phone GPS problem. So for this moment I will stop looking for solution to improve the GPS accuracy (on the GPS app wise), and enjoy using my p9 plus, hope u guys too
Hi, as you say, forget tests, how does it actually work in real life.
Bought my wife one a few days ago and last 2 days testing gps driving around was only seconds to fix and no dropouts in about 1 hour driving. Thats my test.
Great phone by the way, and top quality finish.
If only it had an FM radio...

I find it's slow to lock or find a location, compared to my previous phone (Z Ultra).
If I'm somewhere (even outside, away from buildings, with clear view of the sky) it will take a good few seconds to lock onto my location. Old phone, and even my tablet, are almost instant, taking no more than 1-2 seconds.
This is using Google Maps.
Just a minor niggle, but can be annoying when in the car and needing to find directions quickly.

Staying outside, especially without any buildings around or an empty land, could be harder for the gps to locate you. I am guessing... This sounds not logic but let me tell what I found again...
Recently I use an app which provide public transport info. This app needs gps in order to locate where are you and provide the info for the public transport at the area you are standing at. Just when I switch on the app and yet to switch on gps, my gf helped me to press the "locate me" button and I was telling her don't do silly things as I haven't turn on gps. But right after that the phone located where I was! I was like ehhh...... how come.... I double check and confirmed that I didn't switch on gps!
So again, recently I am adjusting the phone settings hoping to lengthen the phone battery (even though it's already very good. I can use it for 2 days per charge ). I found something very annoying in one of the setting - location services. Numeral time I have chose the 1st option "use gps, wifi and mobile networks (high accuracy)" and it keeps set it back to the 2nd option " use wifi and mobile networks ". I thought it was a bug of the phone but then later when I relate it to the event happened earlier (the public transport event mentioned above), I was thinking could it because I never turn on gps? then I turned on gps and yes, it automatically switch to the 1st option, and when I switch off gps, it auto switch to 2nd option again.
I then realized that other day when the phone located me without turning on gps, I was close to the MRT station which provide free wifi. And I am not sure do you guys ever experience that sometimes when you switch on the map app without turning on gps, the map itself locate where u r (maybe not very accurate but it's at the bearby area), just that when u try to use the map it will ask u to switch on gps.
That being said, I suspect the phone continuously locate where we are by using the wifi router(if any, at the nearby place) because wifi router is location specific? (not sure, maybe expert know this...) and that's why when u don't switch on gps, it is already "pre-locate" where u r and only if u switch on gps it will immediately give u the accurate position. And that also means if u stay outside without any buildings (and so without wifi too), the phone could not pre-locate u and it will solely rely on gps and that's why take some time to locate where u r?
Anyway this weekend I will be going for a long distance trip and will test the gps to see if the phone give good gps signal
just back from the long journey vacation. The phone gps works flawlessly without dropping off at all. And time to locate also excellent within 2 seconds
