Hi all.
I just noticed that with my data connection off the sgs gps locks in 2-3 mintes. t can see most satelites in less than 5 seconds however locking takes forever.
After it had locked and I tunr off the gps in 10 minutes it takes again a long time to lock.
SO I can only guess that he does not remember the position of the satelites and has to connect to internet everytime for a sync.
Wich, indeed is not ok as the satelite info should be the same for a day or more.
So it cold boots every time.
Does anyone know how I acces the gps menu ? Or if there is a software for it ?
I used different gps apps and I could use gps without internet.
I had internet off.
The apps can only acces the gps the way it is set up. It really matters not what gps app you use.
Ofc you can get a lock without internet but it takes too long. I understand about the first lock but the next ones during 1-2 days should be very fast without internet.

Boot to Winmo make sure your weather clock with correct location, tap application tap quick gps check download sattelite fr internet tap download, now back to android check gps on in location setting, now launch google map gps now lock in under 1 minutes tested and worked on all android rom
Or just download the gps-status app from android market (free version) and update your agps settings before you start navigating.
Much less steps to fix satellites and faster.
i dont belive that the gps lib's are stored in the same location, or shared between the os's...
i might be wrong on that, and you might be causeing it to esentialy be a hot boot when it gets into android. if this is the case, then realisticly, you need to add the time for booting wm, aquireing hot fix data etc to your gps start time figures.
personaly, i find that if you have gps turned on, and network location turned on, i get an instant lock with 20m accuracy, first bird locked within 10 sec indoors, and 7 within 30 seconds sub 20foot accuracy.
It seems that the majority of people have absolutely no GPS issues. But I notice every time that I factory reset, I can't get a GPS lock, which is absolutely weird. I can't acquire location on GenieWidget either initially. If anyone else out there is having GPS issues or Location issues then try this.
How to fix for both:
1. Download GPS Test from the market (the free one)
Run it, and leave it running until the GPS On light turns green and it has satellites in use and tells you the meters accuracy. That means a lock. This can take a few minutes.
After this happens, GPS locks very quickly even after reboots, very weird.
Now even after this, GenieWidget still can't acquire location.
2. Turn on WiFi, but don't connect to anything, you don't have to.
When WiFi is on, go back to the GenieWidget and hit refresh.
It'll find your location even though you're not on a WiFi network.
Now disable WiFi and it'll be able to acquire your location every single time.
Weird stuff.
damn... sounds like Samsung is STILL failing with LBS. It's very frustrating on my Captivate.
I turned it on before and got a fix in about 45 seconds. About the same time as my Slide.

It's a one time issue though it seems. I think actually it all depends on getting that 'first' lock. The phone will go to sleep if you wait on maps too long. So I just use that app, go into settings, and hit Keep Awake then leave it sit til it locks. After that, I can get a lock in 1-5 seconds every time after reboots upon reboots.
It locks just as quick as my Evo, 10-15 seconds for me. I use my GPS so much if its not getting a good lock I would return the damn thing over and over until it work how it should. Even 45 seconds is a stretch...my G1 locks faster than that...

Quite right. There's a big difference between "cold" and "warm" GPS startup.
When the phone is brand new, or after a hard reset, it will always be a "cold" start. The phone has no clue about where it is in the world, or even if it has the correct time. So the very first thing it does is to look around and try to spot any GPS satellites. Then it tries to download the almanac data.
For GPS to lock, quite a lot of data needs to be downloaded from the satellites. This takes between 30-60 seconds uninterrupted view of at least 3 satellites. If you're moving around, the view of the satellites may be interrupted, and the phone will have to start over again. This process can be speeded up a lot with A-GPS.
After the first lock, things go much faster. The almanac data is already on the phone, and the position of the last GPS fix is known.
The thing that confuses most people is that an Android phone will try to navigate by other means when there's no GPS lock. By cell tower, or by WiFi hotspot. Cell tower gives your location instantly, but with a very large margin of error. If your position is way off, then you're not navigating by GPS, but by other, less accurate means.
I actually can't get location from the cell towers >.< But yeah my GPS is locking in 1-5 seconds now.
Still no luck with above... will not turn green just stays yellow
I have a I5800L (from vivo brazil), and when im using the stock eclair rom (VIJG7) my GPS gets a lock in less than 20 seconds. But when i update to ANY froyo rom (Kyrillos, InDroid, XXJPM, XXJPN, XXJPQ ... ) my GPS takes more than 15 minutes to get a lock. I've tried every GPS fix i found here, but it still doesn't work. Do anyone have any ideas?
When I had purchased my phone, I never used to get a lock.
Try this...
1. Look through the forum and you will find ways to configure the ntp server.(gps.conf) file.
2. Get this app called "GPS Status" and "GPS Optimization by octy".
3. Start your GPS using the GPS Optimization and then open GPS Status.
4. Go to tools--> Manage GPS-->Reset
5. Download assistance data.
Initially it will take some time to lock, but as u do this more and more, you wouldn't ever require GPS Status.
Just turn on gps with octy and you will get a lock soon.
Have patience.
When i got my galaxy 3 in Pakistan but set was purchased in UK i got the same problem..sometimes i got fix in 5minutes and sometimes when i am in a car i literally try for hour but i cant get lock...
Then i got through one thread sorry i don't know the exact name having lot of coding to fix gps..in this thread i see simple thing..
simple use this code *#*#1472365#*#*
it will open the gps setup2 do nothing and come back to your app it will caught 9 10 satellites in few seconds..
hope this will fix your problem..i am using this trick perfectly on my stock rom use offline maps in maverick..
Same problem here froyo messed up GPS.
Phone finds satellites fairly quickly (GPS status) but to get a fix on them takes forever if a fix at all comes.
Did not have this problem before froyo.
Well I did have some GPS problems but now it has become impossible.
Tried all apps I think, GPS boost, GPS aids.
I think I have the weird of all. GPS doesn't work at all. Network does. When I open Maps aftera long gap with wireless network on, it finds my location within 5 seconds, but wait ................. it jumps into completely different location instantly. originally I am from kolkata, it shows the same at first second and just jumps into JAPAN :O:O .. yesterday got the same thing but in different location, but it was within India atleast .. .. it was @ Roorkee, india. Lost all hopes.......... :|
Hello I'm having a problem with my GPS signal. I followed this guide to fix it but still have the problem: http://androidforums.com/threads/gps-fix-dummies-guide.761247/
I have NO PROBLEM getting my accurate location within 1-5 seconds when sharing location on whatsapp/telegram or other apps. Even opening Google Maps or Waze, they also detect my location very very fast. I'm taking less than 5 seconds and it's very accurate.
The problem comes when I try to NAVIGATE with Waze or Google Maps. This is when I'm outdoors in my car of course. My phone doesn't get a GPS signal. It takes a very very long time, sometimes 10 minutes to get a lock on. The funny thing is that when I followed this guide and I put the airplane mode on, the apps got a lockon on the GPS, but as soon as the airplane mode was off they lost GPS signal and had a problem locking on.
I have the GPS TOOL app installed and outside I get a lockon of about 10-15 satellites of 22 but it doesn't happen instantly. It takes from 10 to 60 seconds to get a lockon. But that is not even the problem. I could live with that, but the real issue is that the signal comes and goes. So sometimes the apps have a lockon for 1 minute and then they lose it for 3 minutes and again and again.
When I'm indoors it takes about 30 minutes to get a lockon on but I get from 1 to up to 6 satellites even though my apartment is the one on the top. There are no other apartments above it so I should have a bit more of a chance to get a signal. But it barely connects and sometimes never. The issue is the same. It may connect sometimes but it loses signal. 1 minute it remains connected and them loses it for 5 minutes and so on.
I attached some screenshots of how waze never has a GPS connection (unless I turn airplane mode on. I'll test this later on the road trying to get some place and I'll update if this really makes the GPS lockon but it's not ideal to have to use airplane mode to get a lock on GPS but not have internet for anyethign else). I have also attached the specifications of my phone. I hope you can help me out. It's a samsung galaxy s5 mini. And mainly I want to know if this could be because of the KITKAT firmware because I have read that many phones have GPS problems now, or if this could actually be a problem with my phone. I hope not becuase it's a new phone. I have one month with it and I'm in Mexico.
Thanks!!
Sorry, this forum covers all the standard size S5s but not the S5 mini. Try your question in http://forum.xda-developers.com/galaxy-s5-mini as there will be more people with the same device as you there.
Hi everybody.
I have SM-N9005 phone, currently running Temasek V16.0.
My GPS usually works fine, however sometimes it finds the satellites and uses them but doesn't get GPS fix for a long time (actually - never, as far as my patience go, which was about 15 minutes). After rebooting the phone the GPS fix is almost instant, with no problem.
So, what can cause GPS to be unable to get a fix, while it can use the satellites. Seems to be software related as reboot makes it fine. It is not ROM related, cause I've had it on stock as well as custom ROMs. Anybody can think of a fix that doesn't require me to reboot?
No, I have given up on GPS of this phone, Snapdragon variant. As you said, rebooting the phone makes the GPS lock fast/ instant, but for normal usage sometimes GPS just won't lock. All I can gather from my personal experience is its about Assisted GPS. When you are restarting your phone the AGPS data is being downloaded automatically, that is how Android works anyway, and that's probably why the phone gets a super fast lock after a reboot. Use app like GPS Status or something to have the phone download AGPS data at short interval, see if that helps in anything or not.
However I have never had any problems when I am outside, the GPS locks within 30-45 seconds no matter what, its the inside problems which used to bug me, but as I said, I have given up.
Hm, I've never seen such a problem. I use my N9005 for travelling across Europe quite often, and it usually locks within 10 seconds to 2 minutes, depending on the location and the number of satellites.
Aside from the occasional glitch, of course. Like going backwards or sideways. :silly:
And it seems to think I'm somewhere off the coast of Norway right now. That one creeps me out quite a bit...
The thing is that when you reboot, it uses all available connections to pinpoint your location. Including your mobile data. (And WiFi if available.) So if you turn on location services right after rebooting, your approximate location is still in the cache.
Triangulation Over Data works within seconds, as opposed to the time required to lock on to the satellites in orbit when it is only allowed to use GPS. If you turn on the higher location modes, it locks much quicker. You can turn it back to GPS once your location has been established.

I am talking about GPS only. I use GPS Status app for a long long time (with my previous Android devices as well), so I can monitor the GPS fix. After reboot I get GPS position almost instant or sometimes I need to go into GPS status app and re-download A-GPS data (which is max 1h old, because of my settings) and then I get my fix.
When my problem occurs NOTHING (short from reboot) can get it to get a fix. I tried deleting and downloading A-GPS data, turning location on and off and from high precision to power saving - it just won't work. Of course I'll get postition from WiFi or cell towers, but GPS just won't fix, even with 12 satellites in use, after waiting over 15 minutes (which should be more then enough, cause whole GPS almanach is transmitted over 12,5 minutes and I get it from A-GPS anyway).
I would start by wiping the phone installing stock rom and testing . Still a problem then its hardware .
