Which radio are you using?
Mine takes couple of seconds max.

I think it depends upon the radio a lot. Some radios are very quick (I am currently using NIKI XX.17 as I need quick GPS locks - now takes seconds not minutes), others are not.

When I first got my kaiser, T-mobile vario III the GPS was very quick to get a fix taking less than one minute to get the first fix after boot up and subsequently a matter of a few seconds.
Unfortunately this was about the only thing that was quick though, so I installed one of Dutty's ROMs which vastly improved the overall performance of the device for most tasks, except getting a GPS fix which all of a sudden was intolerably slow, sometimes almost impossible.
I experimented flashing various radios but nothing seemed to make much difference so I kind of gave up. The other day I upgraded again, to Dutty's latest ROM and all of a sudden my GPS performance is back to how it was when I first got the kaiser, despite the fact the radio version included in the rom is the same as the one I had before. So I'm very pleased about this, but also perplexed. I don't know what factors influence the speed of getting a GPS fix but for me Dutty's latest ROM is good so maybe you should try that.
One thing that I did notice is that getting a GPS fix was always quicker when travelling in the car not standing still.

Which is strange... Normally GPS's are quicker to fix when stationary rather than moving...
I'll be getting mine soon, so once I have it, I will test with the T-Mobile standard and - if I get it installed, being a WinMob n00b myself that is by no means certain! - with Dutty's latest...

It is strange isn't it? But I'm sure it was true in my case. For example I once walked to work with the GPS switched on as a test, I was holding it in my hand so it had a direct line to the sky at all times. When I got there about fifteen minutes later it still hadn't got a fix. The next day I drove somewhere and after about two minutes it had a fix.

As long as I'm outside (or in the car) under clear sky, I get a lock in Google Maps or Telenav in only a few seconds. Inside my apartment, but near a window, Google Maps will eventually get a lock, but it can take it 3-5 minutes to do so. In my office, which also has a window but which faces out to a courtyard surrounded by brick walls (and up 5 stories above my floor), I just cannot seem to get a fix at all.
Outside with clear sky above though, moving or stable, it is very quick - never more then 10s and usually far less.

What kind of buildings and other obstructions were around you? In order to get enough fixes to pinpoint your location it will often have to see sats out to some pretty steep angles. One guy we met who does commercial GPS systems showed us where the birds were from out on a beach. The 4th one was only something like 20 degrees above the horizon out over the ocean.

[Q] S3 Mini - gps inaccurate while running

Hi, I purchased S3 mini around december 2012, one of the main reasons why I bought it was the gps/glonass-feature, since I figured it would provide me with more accurate tracking while running. Previously I had used a Samsung Galaxy Gio phone for running, and with rooting and a gpsfix (changed the server) it provided accurate gps in long half-marathon runs and so forth. The issue with that phone was that the battery life was terrible.
Now, the S3 mini is brilliant in battery consumption, but the gps accuracy has been horrid. It locks a satellite within seconds, several satellites are in use immediately. So, nothing to complain there. However, it is almost one street off, throughout my run. It tracks usually 1-2 kilometers less distance than the Gio, which manages to stay on the road I'm running on perfectly. If I'm to believe the S3 mini, I frequently run in water and through people's backyards...
Now, I have attempted the usual tricks, cleared agps, updated it before runs, calibrated the compass with GPS status indoors and outdoors. But nothing seems to work. Many times the gps will track perfectly when I'm headed, let's say northwards for several kilometers, but then when I turn to go west-east or southwards (for example) the gps accuracy goes off. I'm hoping this is an issue that could be easily fixed, since it's a shame that such a fabulous phone like the s3 mini fails to be a good running partner.
My S3 mini is not rooted, most of the gps fixes only fix satellite locking. My issue is inaccuracy, and yes, many people think it's normal, but having had perfect tracking with an entry-level smart phone like Samsung Galaxy Gio, I fail to understand why my S3 Mini does not excel in this area.
What else should/could I try? or just use my gio while running and hope it doesn't run out of battery in 1,5 hours.

I have also noticed the inaccurate gps of the s3 mini. After some positional testing I have decided that the gps is just not V good on this phone including being mounted on shoulder.
I also have an issue where gps locks up and freezes when the phone sleeps. I have yet to overcome this. I'm hoping it's a kernel issue brought about by flashing.
After years of smartphone soul searching, I now use a Garmin 405cx for sports, etrex10 for work and hiking, and a tomtom for sat navigation. I only now rely on the shoddy gps for View ranger Os mapping on the phone. Based on its performance I've started purchasing paper maps and now use those to navigate while walking and hiking.
This makes me very sad. I love android and like the s3mini. However yesterday I contemplated throwing it across lane 3 of the M20.

Hi, I have a same problem with my new Samsung Galaxy S3 mini and Sports Tracker. And many other reporting this problem. Sports Tracker works fine with my ZTE Blade. The first I thought that the fault is in bad GPS module in my phone. But the GPS work fine with Navi software. I realized that in Navi software the phone screen is always on and with Sport Tracker go in stanby. And when the screen go in standby the gps stop working. And when the signal is repeatedly interrupted then for a long time does not want to connect. Solution is that you in Sport Tracker settigs set Screen backlight to Always on. Now the problem is that the random clicking Stop suspended yor current workout. I do not know if fault is with Jelly Bean ROM or with Samsung Galaxy phones. Later I again tested navi app IGO Primo and if I turned off the screen GPS also go on off.
Phone screen always ON is also not an ideal solution. Because the signal is still losing, but every once for a second.
I tried various apps: GPS Status (settings: Background behavior/The app will keep the GPS running even the device screen is turned off.
But it does not work).Tracker Booster, Keep My GPS Alive, but without success
Is there any solution for this?

I've got the same problem while using GPS in a running application (like runkeeper, runtastic or endomondo).
I know this is an old thread, but I want to ask if anyone has found a solution for this problem.
I would be very thankful!

I have the exact same problem. After two months of GPS hell with my SII I got a new SIII mini. Initial GPS lock and detection goes really quick (22 satellites). If I do a quick turn in running it seems that it tracks a bit of until the end. It may be 100 meter or 200 meter on a 10 kilometer (and people indeed say it's normal, but with my SII it was perfect)
Could it be processor related? I run with a bluetooth heart rate sensor, google music, running app, etc. I tend to believe if I switch of 3G that it goes better.
Any other suggestions on this?

I have basically come to the conclusion that the GPS on this phone is ****, primarily due to the OS sleeping it. Which is a battery saving strategy. We do have very good battery life on these devices.
The GPS doesn't have any issues if an app is using it, like (Viewranger recording a track). This prevents the OS sleeping it. However accuracy of the GPS on SGS3M is poor. But really if you after doing serious tasks that require even a hint of accuracy then purchasing a dedicated device is the way forward. If you run try the Garmin range of fitness devices. If it's work try a hiking GPS I use a etrex 20 for assisting in surveying trees. Recording my movements across a site and the locations of any trees with works associated.
I think the phone manufacturer decided that the accuracy issue was not a concern as many navigation apps would snap the users location to roads and such.
Don't hold out for any solution. I can say the only thing to ensure is the latest firmware. I have the latest which isn't available on the "BTU" location code. However the German firmware works fine with my UK device. Check the Dev thread for latest stock rom, (pretty rooted).

I don't know what to think from it. If I track a car drive with it (using Endomondo), it uses a perfect track to road tracking.
Also initial running tracking using Endomondo is fine. It seems that a sudden change in direction (eg a sudden change from south to nord) let's down the accuracy. It's strange because the device has a very good satelite detection and fast lock.

This morning I had a spectacular improvement.
What has changed:
I installed the latest 4.1.2 official build from sammobile.com
I ran without 3G location services. (pure on GPS)
I also switched the device from being upside down on my left arm, to being straight on my right arm.
Possible something that has nothing to do with it: my work e-mail policy was not yet enabled on the device.
I also ran a slightly other route (but there was still a sharp turn halfway involved), and the signal corrected itself perfectly.
My bluetooth heart rate was enabled, 3G was enabled and google play music was enabled.
So the thing I'm eager to try is: enabling location services again, and doing the route that caused trouble again.
But to be honest ... I think it's the new 4.1.2 build that solved it.

My gf's phone has XXAMG1 build and it has exactly this same issue. GPS shuts down a couple of minutes from start.

Recently I found out that my GPS becomes inaccurate when I enter into the forest. I use it mostly for navigation while mountain biking. The position defers after 10 to 20 minutes for 200 to 400 metres. The position error direction is almost every time in the direction of departure point that means that GPS position stays behind me. When I check GPS reception with GPS test, there are always 5 to 12 satellites in use with estimated error up to 5 metres. The interest thing is that if I switch GPS off and then again ON, the new first fix is very accurate. After that, if I continue cycling, the position becomes inaccurate again. I have tried different programs (sports tracker, view ranger, orux maps, Google maps) with same results.
Any suggestions very welcome.

Same issue here (example included)
Same issue here. S3 Mini and Endomondo. Tracks start to differ after a certain amount of time (refer to attached JPG)
Chatted with Samsung about this issue and they told me that this is caused by the fact that all Galaxy phones have AGPS, where an internet connection is neccessary for the GPS to work. But I am not sure that this is the problem...
Samsung told me that I am the only person indicating this is a problem so it's probably my phone. Perhaps good to file an official support request at Samsung?

My few thoughts on this...
On stock rom everything was working well. except for the rom itself.
On maclaw cm 10.1. gps worked well until after an hour or so of use for tracking. then gps decided that I'm cca 100 meters away from spot where I was standing. it just translated my position and stayed translated the whole time until I turned gps on/off.
On Stock i8190XXAMJ3 gps was amazing, it was locking onto satelittes even inside the house, but it had the same issue like cm10.1 rom.
Now I'm on S5style_i8190XXANA2_v1 and for now gps look good, didn't have any issue, hope it will stay like this.
just to say, I've played with gps.conf, with various apps like gps status, gps test, resetting agps data, trying different apps for tracking and nothing worked. after a while, gps simply translates my position and stays like that.

to reply to myself...
for some reason every stock rom I flashed with cwm apparently didn't flash baseband with it (or something went wrong), so phone was showing original baseband version. then I flashed baseband ANA2 separately and now gps shows no problems stated in previous post.

I've had the same problem on my S3 mini. I'd tried a few apps to track my sport activities before I've found working one - Navime Sport Tracker. Since then I've been using it and faced no problems with GPS and tracking. Unfortunately app only works in Poland. So you may ask why I'm writing about this. I do so because I reckon that problem sometimes lies in a tracking app itself. E.g. in the same place where Navime was detecting 7-13 satellites Endomondo (with identical GPS settings) managed to find 1 or 2. That's how I solved my problem. And one more thing - I use stock-Samsung Android 4.1.2 (newest).
My usual GPS config:
- GPS is ON (obviously)
- using wireless network to fix GPS is OFF (option on the top)
- GPS data available for Google services is ON (option on the bottom)
- data connection is ON

Hi pcm266
I know this is a reply to a post a year old, but this is the closest description of the problem I continue to experience. Perhaps you and others are still looking for a solution.
This is NOT simply a matter of poor connections due to loose screws. I tried a month ago tightening screws, checked every setting but the problem persists. Loosened then tightened screws again yesterday. Today I ran with both my S3mini and my old Samsung GIO. The GIO recorded perfectly!
Your sentence "Many times the gps will track perfectly when I'm headed, let's say northwards for several kilometers, but then when I turn to go west-east or southwards (for example) the gps accuracy goes off. " is pretty well what I see happening.
What is puzzling is that S3mini worked perfectly in a race on 29 March. ??? Have not been able to repeat that.
Tightening screws is certainly not helping me. I am sure that this is a software error. There is a consistency in the type of error that is not is the type of error I would expect from intermittent connections.
Another strange thing is that the S3mini tracking is pretty good when travelling in a car. It is when I ran - which is of course much slower than a car - that the tracking is worse. Something to do with collecting too much data and doing some sort of averaging????
My son runs with an S3. Never had a single tracking problem.
A tip re the GIO battery: The Lithium-hydride batteries in laptop battery packs have the same charging characteristics as the batteries in the Samsung phones. I simply soldered wires from the contact points in the phone to a battery taken from an old laptop pack. (Usually when these battery packs fail, most of the individual cells are still good. I use them in all sorts of applications. ) The battery is fastened to the back of the Gio with duct tape. The phone no longer has a simcard in it, so I keep it on airplane mode. The battery stays charged for days!

Guys, I've never experienced this GPS problem. My S3 Mini has completely accurate readings both in car and while walking. You can try and update your phone to a newer firmware version if it's still on a firmware from a year ago. Don't know what else to suggest, God bless my S3 Mini for not having this problem, 'cause I use GPS frequently

Hello, I have the same problem with inaccurate gps after some time. Is there any solution. I use this phone only for running, so for me it is not a problem to flash another rom. I hope someone can give me a solution or a rom that works while running.

GPS issues

So I got my note the first day it came out and a couple days latter used my GPS and noticed it was off a little, anyways I downloaded GPS status and thought it'll fix it but I never used it or tested it to see if it got fixed or not.
I used my GPS a couple days ago and the GPS seemed to be worse than last time, if I stopped at a stop sign or a light the GPS would freeze for about a minute or two and then catch up, I'd be in the highway and it'll show I was getting out in an exit even tho I was still going straight and it would really route and te route again. So is my GPS just faulty or is there a way to fix it?
Ps. I uninstalled GPS status since it looked like it made it worse

What kind of case are you using? I am using the official Samsung blue protective case and it makes my GPS barely work. As soon as I use the phone without the case my GPS locks in to 10 ft no problem.

I am using the tech 21 case from Tmobile most of the time.
All I have to do when case is on and GPS isn't working is shake the phone and it works/locks.

GPS issues, still haven't found a fixable solution after 9 months!

I've been having GPS issues with my Mi5 since I got it last July. Issue is simple - it takes a very long time to lock a signal, then it never stays locked for much longer after.
I've tried all sorts of gps.conf edits (including the recent Magisk fix), different ROMs (MIUI, LOS, RR), different MIUI firmwares, and still the same issue. Using GPS locker, it views about 25-30 satellites immediately, but can take a while to actually "use" any of those satellites.
The GPS works fine if I'm standing outside on the street (locks in about 15-20 seconds), but if I get in a car or on a bus, then it can take up to several minutes to lock and does not stayed locked for more than a few minutes. I was using my GPS on my bike and it worked fine, but as soon as I passed under a bridge, it lost signal.
I find this whole thing very strange and I've searched everywhere for a solution with no results. I almost seems like it's something hardware related but I have no idea what. Any help would be greatly appreciated. In fact, if anyone can find a solid solution for me, I'm willing to reward you with a gift. I'm serious - because it's so frustrating that I've even considered buying a whole new phone.

I really think it's an hardware problem my friend. GPS shouldn't even take 20 seconds to fix on a Snap 820. My cheap Huawei smartphone locks in literally 3-4 seconds (when it's slow) outside. Maybe the gps antenna on our Mi5 isn't well placed or doesn't have a good sensitivity compared to other devices. Flashed back the stock miui, didn't have an improvement so I think we can jump to a simple conclusion....

Hello vorsprungtechnik, got exactly the same issue as you describe, do you found something to fix this ?

its hardware problem. antenna doesnt enough. we had two choices. modify antenna or improve with software. my advice is try some custom rom because xda devolopers really good at this. i prefer Syberia Rom, give a chance. My gemini already have this rom and agps integration no any problem about GPS.

Anyone having GPS issues?

I have a Note 9 on Sprint, and everytime I go to use Waze, or Gmaps, I do not get a GPS lock. Restarting the phone fixes it, but by the next day, the issue crops up again. Anyone else seeing this?

I too have issues GPS, my. device is constantly loosing its fix. It aquires 20+ Sats very fast, then fix within a few seconds (what is absolutely fine), but a few seconds later it loses the fix for a few moments, fix again, lose again, and this then goes on forever...
I now have the device (512 black Exynos ATO) since a week, but I started to observe this behavior since today!
How is the GPS performance of other users?

Had it happen again today. Went to use Waze, and it would not lock on. Installed GPS Test, and it shows no sats, nothing. Restarting the phone does fix it, but it's a pain. May have to contact Samsung/Sprint.

Done a bit of geocaching and it was spot on the whole time. Also used at work , both trouble. US unlocked 512gb

Note 9 gpsfix lost
I have the sane issue..i have tey many thinks but i havent locate the source of the problem yet

I had similar issues but it turns out the location method is always set to "phone only", changing back to "high accuracy" fixes it.

GPS signal is lost in Goolge Maps after update N960FXXU2ARJ1
I have a Note 9 since a few weeks now and it worked perfectly until I installed the latest update (N960FXXU2ARJ1), the one with the fix for the photo quality.
Now when i'm using Google Maps or Waze in my car with Android Auto my GPS loses fix. Google Maps constantly says that the GPS signal is lost.
GPS Status or GPS Essentials show 10 to 15 satellites in seconds with a GPS fix. So GPS seems to work fine. Only when driving the signal is lost.
Maybe there's a bug in the update?

Note 9 on ATT, sporadically it will ask me to turn on high accuracy setting and submit random anonymous data, but it keeps asking me, even when I haven't turned the GPS on. When I hit accept it turns the GPS on, I assume it's the weather widget or something like that needing a location.
My actual issue is I already hit accept and don't want to keep hitting accept and on top of that it will sometimes default to battery saver GPS which is useless.
I dont know how to keep it at either high accuracy or phone only when I go to turn on GPS.

Still having the issue....happened yesterday.

No issues here so far. I'm inside my apartment on the third floor, so sandwiched between apartments. I turned off WiFi to make sure it wasn't using my router. Opened Google Maps and it immediately locked on to me. Right down to what room I'm in.

I still don't know why my gps keeps trying to randomly turn on and asks me to accept or deny, regardless what I choose my GPS turns on without me turning it on.

Same issue here. Losing GPS and the finding a fix again shortly after. Happens in locations with no problem before and changes status rapidly. What's going on?

Looking for this problem in another forums I've discovered that the problem is related with Power Saving Mode in Samsung phones.
Yesterday I disabled the power saving mode and it worked flawlessly through Android Auto, even with the phone at the glove box I had a consistent and precise GPS fix.

The answer is easier (and more disappointing) than anyone might guess.
The phone simply, has a mediocre GPS unit.
But it's a PREMIUM DEVICE?

And? No one cares. OnePlus has been featuring horrible GPS units since forever.
How do you know?! Can I verify?

Of course, you can verify. Install GPS Test (or any other GPS app from Store) on two or more phones of yours (including the Note 9, duh) and see the results.
Inside your house, outside, in a car.
So other devices have better GPS?

Only Notebookcheck (from what I saw) features GPS reviews, and they don't check all phones.
My experience. (from the phones I tried, owned, had. DB = Dual-Band GPS.)
Note 4: 5/5 || Always worked superb.
Note 9: 3.75/5 || Bit better signal than the 7 Pro, but puts you off by a street or two in the car. It's nothing good/great.
OnePlus 6T: 2/5 || Horrible. Even on a plain street has difficulties.
OnePlus 7 Pro [DB]: 3.5/5 || Not bad, not good. Has trouble finding you in the streets. Works OK until you enter a place with various roads (like an interchange).
HTC 10: 4.5/5 || Good. Stable, solid. Works great really.
Huawei Mate 10 Pro: 5/5 || Perfect.
Huawei P10 Plus: 4/5 || Had some trouble on foot, but okay-ish.
From what I saw, learned:
- Dual-band does NOT matter. If the module is bad, signal will be bad.
- Car glass can block out a good deal of the signal. Heated glass, heat-reflective glass. Ford, for example, uses both on cars. Does not mean it will like reduce signal by a LOT, but will make it worse.
- Phone cases matter. Even thicc plastic cases can reduce signal.
From what I read lately... the following high-end phones have good GPS modules.
- Pixel 3a: Good, thought not flagship SOC/internals/ram/storage. Only 1 camera.
- Huawei Mate 20 Pro: Great phone, albeit bit dated by now. Huawei updates are erratic, support/warranty is horrible. I had huge fights with them, since my family had 4 flagship Huawei devices. Court was always there, legal actions, threats. It's insanely bad. And now they have the Google problem (US vs China), and the phone is 100% locked down, no unlock possible. Unless you buy at external shops - but then you can't get warranty on them.
- Samsung A70: The horrible in-screen fingerprint reader ruins this otherwise perfectly great device.

GPS signal lost a few weeks ago and I tried everything but no signal. Is there anyone who can help with this topic? Galaxy Note 9 - SM-N960FZBDDBT
