Hi all,
I am new to the android OS, got my galaxy s a week ago.
I still keep my HD2 and to be honest I may sell the galaxy due to the poor gps reception and keep the hd2 for the next year.
The other thing I do not like is the fact that I cannot program the buttons behaviour.
Any way my question is, is it possible to disable the build in gps and use an external Bluetooth GPS Receiver?
The gps on my hd2 is miles, miles better.
I dont think its possible in this version of android. There is no way to tell the app to use the external gps instead of the internal one.
All we can hope for is a fix from Samsung.

what is all the fuss about android then...
it doesnot support such a basic thing...

GPS won't start
Hello, I am experiencing an issue with my phone and I was wondering if anyone knows a solution.
Basically the GPS receiver won't turn on when an application requests it, so it won't get any location information (the gps notification icon doesn't appear at all). This is definitely a software issue, because if you go to the settings menu and keep fiddling with the location settings (gps on<->off, wireless on<->off) at some point it WILL turn on and work correctly (and the gps icon appears), but randomly afterwards it will go back to not starting up again and you have to go back to the settings menu.
Is there a workaround for this? I'm hoping that a firmware update will fix it, but in the meantime is there anything that can be done? (I'd prefer to wait for the official firmware before flashing it).
Not really a fix but Extended Controls can make a switch on your home screen that will flip the gps function on and off, that will save some time if you have to go into that menu a lot.

I can confirm the same issue, rumour is that the upcoming firmware is going to improve the GPS a lot.
You can also use the 'Power Control' Widget that comes with the device.
Here you can turn On/Off a number of items, one being GPS.
I had this issue but it's just a case of going into settings and toggling the gps off and on again.

Good to know about the GPS on/off switch.
I was always rebooting my phone to get the GPS back to work.
There is an option in the secret GPS menu where you can set it to cold start, instead of hot start. Fixed it for me.

Bluetooth External GPS
Hey guys. I wanted to know if we can 'natively' from within Android 2.1 / Samsung Galaxy S use an external bluetooth gps...
In the bluetooth menu I can conenct to the TomTom bluetooth gps module but it can't be paired...
however after some digging I found this app:
http://www.androlib.com/android.application.googoo-android-btgps-AtDE.aspx
It does what it says. I get satellites straight away.
Now one big big problem with this app is that it closes as soon as I try and open another app by pressing the home button or even holding down the home button to switch between apps...
when the app closes it ends the connection between the TomTom bluetooth gps module meaning by the time a satnav app has opened the message box pops up and says 'do you want to enable gps'
why does this app close when you try open another app? No other apps like Asphalt etc close like this...
is there a way to use the external gps?
many thanks
From my limited understanding, no it's not possible. I don't know why, but Android has been a bit slow on the uptake for Bluetooth.
It's taken to FroYo to actually get Bluetooth Hands Free dialling - we'll see how good Google is in interpreting what you say to it, so far, it hasn't been successful for me on the phone itself let alone Bluetooth.
With regards Bluetooth GPS, I understand that it isn't possible. There would at least have to be some kind of underlying interface to overrule the internal GPS and feed the Bluetooth GPS information into the OS in place.
I want it to be possible, then we wouldn't care so much about broken GPS's.

Another GPS fix
Hey guy give this a try and let me know if it works for you.
http://theandroidrevolution.blogspot.com/2010/07/android-tips-tricks-samsung-galaxy-s.html
working like a charm, faster fix and i can actually use the GPS while driving (EU)
Isn't this like turng skyhook on?
Ie ,..whilst locki it uses wifi to identify where u are?
this fix it seems very accurate in Maps, whereas all other "fixes" did not work for me.
i don't notice anything different in GPS tester (i still hardly get any satellites if any) but in Maps my position seems to be very accurate....i'm just inside in my flat, but all other fixes never helped me before even in this situation.
Hello
Thanks for your suggestion for a GPS fix
Immediate I can not see the big difference in standard configuration and the change which you refer to.
I still have a unsettled GPS fix when I use Google maps.
However, I think I can see a slight improvement in the Google navigation. Now I remain almost always in the correct lane.
I use (default) I9000XXJF3
I've read that a newer version should resolve the GPS "problem", but is it possible to change the parameters of GPS I9000XXJF3 match the parameters of the new versions. ?
And just one question more.
If I close the GPS from the phone to calculate my position after mobile mast or WIFI.
How do I get it to find my location by WIFI.?
Hope for a response.
Thanks
Herman
This fix gives an instant , i mean instant gps fix with a clear sky.
on gps test gets 8-9 satellite now , when previously i could max get 1-2, that too not connect.
thanks a ton for this.
outside this fix i also had operation mode as ms based and had skyhook on.
I found this suggested fix a few hours back as well and have been trying it out.
I didn't get much better results from it to start out with but having played the accuracy setting I've found putting this up to 150 seems to make a big difference. Once I made this change GPS Test seems to show that the Galaxy is a bit less picky about the signal strength it needs before making a lock.
I've not gone any further in testing accuracy numbers beyond 5, 20 (the default I believe) 50 and 150. It might be worth trying other values.
Hey guys I am new to the community and just recently picked up a vibrant for being a loyal T-Mobile customer haha.
Anyways I just wanted to point out something that I noticed while trying yo fix my GPS issue or non-issue. I have detailed my steps exactly so please read below:
1. Got vibrant out of the box and after 5 tries connected it to mini kies and updated to 2.2.
2. Applied GPS restore from market. It did not work at first, but after stepping outside it worked.
3. Tested the GPS and it works, I am amazed and thought the issue is fixed.
4. Went to my other residence 50 miles away, tried GPS, big fail.
5. A week later I remember the GPS issue and try it again at my place, fail again.
6. I became curious and tried Google sky, with GPS on. Google sky reported longitude and latitude. I am in shock because I thought the GPS was broken. I turn on Google maps and bam, location is found again.
7. I become more curious and try the same approach 50 miles away at my other residence, bam location is found again.
My conclusion is something is up, can any of u guys explain and/or try my method?
Thanks!
I've found that google maps doesn't like a cold GPS start, that is, the first time used after changing locations or waiting a few hours. But if I use another gps program, like gps test, wait for it to lock (which is usually pretty fast), then close out and open google maps I'll get a near instant gps lock since it's a warm start. Something about google maps doesn't seem to want to convince our phones that it should get a gps lock.
Google Maps is terrible with cold starts. The solution is to use GPS Test to lock into more than 4 satellites and then open Google Maps. You were basically doing the same thing with Google Skymap, but Mike Lockwood's GPS Test is better because it keeps polling the GPS while you check Maps.

+1 I found this to work the best as well. I use Ulysses Gizmo though
Either way, with the New KB1 modem (you can flash that by itself) this REALLY improved the GPS
thanks guys your input helped me clarify alot because i always thought my GPS was broken because of google maps didnt show my position.
The iPhone I had and my mytouch 4g and g2 both do not have this problem, this is vibrant isolated, correct? I mean the cold start to the GPS from Google Maps.

Plus 1 - KB1 has great GPS.. I did however have the hardware problem. So the combination of fixing the hardware problem and KB1 has my GPS running better then ever.
I'd like to make a unique single thread with all the issues related to gps on DHD and the procedures/tips to make it work better.
MY EXPERIENCE
I was ready to go to dinner to my girlfriend's uncle (50km far away). I bought my DHD two days before. Ok, let's try gps. Google navigator. Started driving and my phone didn't get a lock. After five minutes of driving, i needed some help from navigator. Nope, still no gps lock. I stopped the car, got out with DHD in hand and lock again in two minutes with the sky in sight. No problem until destination. At the end of the dinner, on the road again. For the first 3 minutes, gps lock. Then lock lost, gps icon blinking and nothing. Tried to reload the phone. Fast boot first time and complete reboot the second time. I didn't stop the car this time, tried while driving (my girlfriend handled telephone while i was driving ).
It took 45 minutes to get lock again. Thanks god, i learned the route on the journey there.
The same thing happened again three times in the next days.
I thought that some software installed corrupted my phone.....(sorry, i was used to the windows mobile whims!!!!).
Hard resetted, but the problem was always there. Without logic, sometimes i had gps lock, sometimes not. Sometimes my DHD was keeping the lock until destination, other times gps lock was lost while moving.
GENERAL CONSIDERATIONS
Not all the people complaints about gps on DHD. I don't know why but there are many people who have problems using it. I think that, except for the faulty devices with defective gps chip, the behaviour is the same for all devices. Only the people perception about the performances of gps are different, and their behaviours of use. I had different expectations about gps. I was used to start driving without gps lock, my HtcHD would have always found lock in one minute anyway. Even if moving, even if many clouds or raining.
People who arrived to Android coming from Windows Mobile do experience a general lack of speed in locking gps position and a very different way about gps is handled by the OS.
My DesireHD hardly locks gps where my previous HtcHD locked gps in few seconds.
The same difficulties I have now with DesireHD, I had them too when I installed Android on my HtcHD. But I thought it was the unstable Android SD ROM's fault.
Another issue is the speed of hot start: DHD seem to have a very very short term memory in fact of gps. Hot start is really hot only if you reconnect within short time.
My HtcHD was able to reconnect in few seconds even if hours passed from the previous lock, if not moved.
My new DHD needs more time to lock, even if the previous lock was 30 minutes before. It happens to take 45 seconds or more to lock again if the sky is not completely in sight.
Even if I get lock with GPS Status, shutdown the program and I reopen it few seconds after, gps lock is not immediate. It takes almost ten seconds to lock.
I think I have to forget the Winmo performances in fact of gps, on Android.
(I think it's the only thing i'm gonna be missing, anyway......)
I think i'll have to wait for the lock before start driving from now.
ISSUES EXPERIENCED BY USERS
- DHD locks gps but when moving it loses the lock and it stays for minutes (from 10 to 60) looking for it again. -
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock. Phone never ever locked gps, whether indoor or outdoor, with the whole sky in sight.
Try resetting AGPS data and let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
If you never ever succeed to get a lock, you should consider to have a faulty chip on your device. I think it's better to contact HTC Repair service.
- DHD behaves with no logic. Sometimes it finds a lock in seconds, sometimes it takes ages to find a lock.
Let DHD get an outdoor strong gps lock for some minutes before starting to move.
- DHD is unable to find a lock if any data connection is available.
Try resetting AGPS data e let your phone get a lock without data connection, outdoor with the sky in sight on a plain stable surface
TIPS
Do all of these steps. And, except for the first, try to do them all the times you use gps. And evaluate the improvements, if there are.
One time procedure:
- Force the phone to lock gps without any data connection and check APN type (see below for the link to step-by-step procedure).
It is important to put the phone outdoor on a stable and straight surface in order to get a strong lock, with a complete view of the sky.
My advice is to empty a-gps data BEFORE doing this operation (this can be done with GPS Status - Menu => Tools => MAnage Agps state => Empty data - The program is free and doesn't need root permissions)
Before every use of gps:
- Use FasterFix (needs root permissions) to change NTP server zone. The system/etc/gps.conf file contains parameters for NTP server and AGPS data. In mine i find that the ntp server used is located in northamerica. I live in Rome so I use Fasterfix to change it, forcing to use european ntp server. I don't know why but Android changes by itself this file, putting again north america server, so i have to change it more than once in a day to keep it using european server.
NOTE: Fasterfix gives back an error the first time you open it, choose the seerver and try to apply it. Only the second or the third attempt, it returns an ok result. Don't mind error. Don't worry about it. Even if returned error, it did its job anyway.
- Synch Device clock with atomic time. I use ClockSynch (needs root permissions), but every program capable of doing the same thing can be used. This is intended to help device in calculating your position. More accurate time means less corrections by the software, faster position calculating and a more accurate position.
- Let the phone get a strong lock BEFORE starting to move with your car. A couple of minutes before, you should let your phone on a stable surface, with sky in sight. Outdoor, obviously. Better if outside the car.
This thing could seem stupid, i know. But let your DHD get the lock in a place where it has a good view to the satellites. Let it acquire precision (you can see it in the left middle part of the screen, using GPS Status). Start moving only when precision has reached a minimum value (expressed in meters/feets - lower value, more accurate). You will see that gps lock will be more and more stable than before.
- Use a task killer program to kill all the processes which may use gps. I noticed that if one or more program able to use gps have been left opened in background, sometimes, without logic, something goes wrong and Gps receiver is no longer reachable by software.
In this situation if I open GPS Status, I see gps icon blinking, but in fact no satellites are seen by the program. I mean that on the screen is not shown 0/3 or 0/5 satellites. On the screen i see nothing about the number of sats, neither 0/0, empty. And in some situations this thing cannot be true (i.e. if i am completely outdoor with a perfect sky view).

Just 1 possible solution for you, have you tried to upgrade your radio? This may sometimes help solve GPS problems.
Sent from my Desire HD using XDA App
No, I didn't upgrade my radio.
I'd like to do it but i'm very hesitant to mess around with my phone like this.
P.S. Let me know if you had some improvements.

Updated radio can make a MASSIVE difference. One of the best things you can do to your phone if you're having any kind of GPS / 3G / Wifi issues.
Go to:
Menu > Settings > About Phone > Software Info
Where it says Baseband Version, this is your radio version.
For me the most annoything that happens with GPS is that when playing a music and using at the same time an offline map gps program, when a voice or some ding dong sound happens, the music played stops and resumes after those gps sounds ends...
I think this is due to Android sys... even WinMobile it's better on this...
Thanks for the tips. My GPS is locking on very quickly now and even inside buildings. I used clocksync + GPS status + Fasterfix. Fixing to around 8 - 9 satellites indoors and 12/12 outdoors.
Done.
Great.
It Works!!!!
initially it would take me a good minute or two to acquire a precise location INDOORS, now it does it in 10-15 secs!!!!!!
i was already using GPS Status, this is with FasterFix.
Thanks.
so strange I never had problem with GPS, always fixes in less than 10 second and never loses as well.
I use iGO and it never let me down.
I had problem with gps-lock from the beginning.
Tried the link above "gps-lock without dataconnection"
Now it locks within seconds
Sent from my Desire HD using XDA App
Personally, I've had no problem with gps for apps such as Google navigation where the screen stays on.
It's a different story, however, for apps like cardio trainer where the phone loses gps lock when the screen is off. I understand this is a known issue with Android 2.2 and has been fixed for 2.3+. I don't know if anyone else has problems with this.

but mine desire didnt work? first when take out the sim card ,reset and download data ..it work like charm..lock around 10 sec..then put sim card back it took age cant find satelite to lock..
anyone know what wrong?
On my DHD, indoors, GPS sucks badly.. apps such as "aroundme" its pretty useless, just hangs finding a signal. but outdoors when I use navigation, etc it works okay. I dont use GPS that much anyway, so cant complain. It is a tad annoying when your indoors and cant find stuff though.
I've had really big problems with my GPS.
Could not get a lock so I rooted my phone and upgraded the radio. Changed the gps.conf file and reset A-GPS settings and tried GPS without a dataconnection. None of the suggested things above did work, so I downgraded the radio to stock and unrooted my phone and sent it to a repair center.
Hopefully they will fix it.
I have a Hero (root) and a Desire (stock) and they get a lock on within seconds and works flawless even indoors.
I guess HTC has a lot of faulty GPS modules in their Desire HD mobiles, but not all are using GPS so therefore we only hear about some of the problems.
Trying the Nexus one fix as in the first post, after taking SIM out, I do not get any GPS signals on GPS Status, if I put SIM back in I get fixes but GPS unusable as it keeps losing connection whilst in journey. The steps I have taken so far are as follows:
* Take your SIM out of the Nexus One
* Power on the device
* Turn WiFi on
* Turn GPS on
* Open application: GPS Status (ver 3.4)
* Go into its Settings menu
* Click on GPS and Sensors
* Click Manage A-GPS state
* Click Reset
* Click Manage A-GPS state again
* Click Download [You'll see a message telling you that a data connection is needed, ignore it]
* Now put your phone on a stable, straight surface in order to enable the phone to get a lock, within GPS Status. This time, you’ll see your phone get the lock way faster than before.
Any help will be appreciated.

There's some developments about this issue...
Or one use the nice HTC Gps Software (at least the version that cames with gingerbread) or use the iGO Amigo.
I tried the iGO Amigo and I finally can listen to music at same time when the voice from iGo speaks!!! There's no interruptions at all like on the majority of GPS softwares that I tried on my DHD (don't know how it works on another devices)
I think that this issue is something that is only developers fault cause initially I thought it was due android design, maybe it was only possible to play something only from one app at a time. (ie. not play two things from two different apps simultaneous) but I figure that after all that is possible.
Bad developers!!!!
GPS Problems: finally the solution
Hi all,
Here I want to tell my experience with HD Desire GPS to help all those who were (like me) desperate.
The way to solve exists ! Read to the end to know how.
I bought my HD Desire in January 2011 (from Euronics in Rome - Italy) and after one week of use the problems began with the GPS.
It did not fix more ... but above all there were more than 1 or 2 visible satellites ... even in open sky, in good conditions, even outside for 30 minutes.
The phone was obviously still immaculate (without root and with the original ROM and RADIO) then I went back to the shop where I bought ... and using GPS-Status the seller has found that actually did not work.
Very kindly he changed my on the flight the phone ... I installed GPS-Status on the new phone just replaced and now everything works fine (fix in less than 10sec and 7 / 8 satellites visible).
I came at home and for 2/3 days it worked wonders but soon it began again with the same GPS problems.
No more fix and at maximum 2/3 satellites visible.
Building on the fact that the phone had been replaced and ... GPS Status actually had made a fix in less than 10 seconds ... (When I had replaced) ... I said, Sure ... is certainly a software problem and not an hardware one ... because the phone is a new one.
So I did a factory reset ... reset all settings as the original ... and retried. Nothing.
The GPS was dead for the second time in two weeks.
Then, I began a careful search on various forums (both Italian and international).
I've tried everything ... really everything ... but nothing. It does not work !
Tried GPS-Status (A-GPS Reset, Download), then fasterfix (it.pool.ntp.org) then I started to change ROM (root, S-Off and ENF S-Off), then I tried all possible Radio and RIL in all combinations. Sometimes happen that the fix was very fast and this gave me the illusion (temporary) of having finally found the solution. However, on time (sometimes even after a few minutes) the problem returns back!
I also tried to clean the contacts of the GPS as shown in this video on youTube(h**p:/*w*wdotyoutubedotcom/watch?v=7qm_z65LA8k).
At the end ... after 4 months of trying all... I sent back in warranty the phone to the HTC service (S-ON and leave to unroot because it was under warranty).
After 10 days of impatient waiting, HTC gave me back the phone and say that the GPS was faulty and had been replaced.
I redid a restore using Titanium Backup Pro ... restoring back all in the exact same conditions I had when the GPS was not working.
Now everything works wonderfully !!!
Im using the original ROM (RUU 2.36.405.8), original Radio (12.54.60.25U_26.09.04.11_M2) and the original Kernel (2.6.35.10-g0956377).
Fix in 10/20 sec (everytime), with at least 7 / 8 satellites (tested for several days now).
Moral of the story ... There are lots of HTC Desire HD phones (probably the first stock) that today are still in the form of stocks and inventories in some shopping malls / shops with the GPS module that is broken !!! (it works for a few days and then no longer works).
The only way is to send back your phone in warranty and ensure that GPS module is replaced (having first restored with all unroot and S-OFF as otherwise the warranty does not apply).
Believe me ... if you have tried everything ... this is the only way!
Now I'm an happy HTC Desire HD owner (with Gingerbread) with a GPS which is a splinter.
Im currently using Navigator, Google Maps, CoPilot and everything works great !
I hope this post may help and comfort those who are desperate and can not run the GPS on the Desire HD.
Greetings to all.
Andrea.
GPS not working on SM-N910F. Show much "In view" satellites, but 0 "In use"
Have problem with GPS. It never can find satellites, even under clear sky. "GPS Test" application always show many "In view" sattelites and zero "In use" satellites.
Changing android version (even CM) doesnt help.
Anyone help! How to fix this problem?

Same issue here, I'm starting to think hardware issue, did you find a fix?
I had the same problem and I tried everything, different ROMs, different programs, to no avail.
It probably is a hardware issue. The GPS connectors inside the phone do not make contact with the GPS antenna on the backplate. Open the phone and raise the connectors a little, very gently, so you don't break them. Before closing it, put a tiny paper under the connectors, so it won't happen again. It's not very easy, but not too hard either.
Thanks
I ordered a phone repair kit (small screw driver etc) yesterday as I suspected the same. I'm going to open her up when it arrives, I'll let you know what I find.
Cheers for the reply

Took mine apart, extended all the pins I could see bilut same issue. Where exactly are the GPS pins and antenna? All I could find online was stuff for the note 3.

To the right, as you see the device from the back. It's the two tiny pins on the up-right corner.

I'll take another peek tonight
Just opened it up again, give them a good extend but the issue remains. I think I'm a special case though, I got mine from Hong Kong (sent to UK) and then through a custom ROM Modem/Bootloader on without testing anything - idiot. So after further reading I think my issue may be related to CSC stuff, although I'm not sure exactly what that means yet - I'll keep reading.
Cheers for prompt reply.

Hello, I had the same issue when running android 5.1
It was after waiting a long time to get some good gps lock. Assuming it was an hardware problem I also checked out the 'pin' issue.
But amazingly, when flashing a android 4.4.4 rom, the gps is now awesome!
It now has almost instant lock everytime and I use it all the time for tracking my running and cycling. So I noticed the difference quickly between android 4 and 5 with the gps. It's like there's a big software bug in the 5 version.
Thanks choko, the one good thing I did before the flash was take a picture of all the info in "about phone" and a full backup including efs etc, so one of my steps when I have more time is a full roll back to stock (4.4.4).
Just need to locate the stock bootloader and modem for my "special" Hong Kong device.
Cheers all

I couldn't get a GPS connection on my Note 3 and was about to take it apart when I came across GPS Status Test and Fix I ran it and then everything was sorted! I've just bought a Note 4 and thankfully the GPS worked first time (I'm on MM now)
Thanks wold
I tried that and clicked the buttons at the bottom and it just varied between 0/19 and 0/24, not sure if that means my phone is "seeing" the sats but just not locking or what.
Feel so close to a fix yet so far away as I've tried everything apart from a CSC reset thing I read elsewhere. But that formats your phone so waiting for when I have more time.
Cheers all

Okay all - tried flashing back to my original backup from when it was new but it got stuck in reboot loop. I found the exact firmware online that came with my phone, flash it including modem etc and the phone booted as new, no warning sign it had been rooted or any recovery's installed. Even got offered some security updates once I'd logged in. Even after all that and comparing my ABOUT PHONE info to my original screenshot and confirming they all matched exact, I still have the same problem.
Some times when it's broke, I guess it's just damn broke!
Good luck with your journey's my friends, may the odds be forever in your favor.
This solution is the one that finally fixed the GPS on my Note 4 (currently on Android 5.1.1).
I had tried all the other options I could find on the internet (clearing cache, removing SD card, removing/reinserting SIM, calibrating compass, changing location modes, clearing AGPS data, etc., etc., etc.). None of them helped. Powering down, removing the back, then removing all the screws (about a dozen I think), then twisting the case gently several times in a "hand wringing" motion, followed by pushing firmly around the back to reseat anything that may have come loose inside (I did get a satisfying click of something snapping back together around the camera area), and then reassembling everything finally fixed the problem.
I now get a GPS fix in 3-4 seconds while inside on the main floor of a two story home. I get a signal-to-noise ratio that ranges between 15 and 30 and typically get a fix on around 10 satellites now (while indoors). Outdoors the performance is outstanding; the SNR is even better and the time to fix is nearly instantaneous. Before the fix I was lucky if it even got a fix on 3 or 4 satellites and it would often take several minutes, if ever.
I use GPS Test by Chartcross Limited to confirm satellite signal-to-noise ratio and time to first fix. I used to use GPS Status & Toolbox, but I prefer the GPS Test GUI and it has many of the same functions (including clearing and updating AGPS data). Incidentally, before the fix if I cleared the AGPS data I was lucky if I ever got a fix indoors; usually I had to go outdoors and wait many minutes to get the first fix. Now, I will get a fix while inside within 15 seconds after clearing AGPS data.
My Note 4 is like new again. And, as an added bonus, my battery life seems to have improved immensely. I suspect that the poor satellite reception made the GPS run nearly full time trying to get a fix. Now it seems to have dramatically reduced the battery drain required to run the GPS. I suspect that many of the reports of poor battery life are actually Note 4's that have poor GPS satellite reception problems.

Have problem with GPS. It never can find satellites, even under clear sky. "GPS Test" application always show many "In view" satellite and zero "In use" satellites.
Changing android version (even CM) doesn't help.
Anyone help! How to fix this problem?

I had the same problem it shows many in view 20 OR 26 but doesn't fix to any of them. SM-N10F
1-Opened my phone clean all the points pins No avail.
2-Forced Stop the location services then In view 0 in use 0 (google play services and google play-store)
3-Changed online found GPS drivers gps.default.so etc..... Goes to boot loop.
4. Still waiting for solution.
Test Apps ---- GPS STATUS AND TOOLBOX PRO GPS TEST AND FIX FASTER GPS
PUT MY IMEI TO IMEI INFO AND IT SAYS THAT ITS SM-N910C OR SM-N9108V MODEL PHONE.. STRANGE I DONT THINK SAMSUNG KNOX WILL LET OTHER MODEL FIRMWARE BE INSTALLED ON THIS HARDWARE. PLZ CHECK YOURS AND REPORT.
AND DONT SAY ITS A HARDWARE PROBLEM IF IT IS THE GPS IS INTEGRATED IN QUALCOMM SOC SO IT SHOULD BURN ALSO.
Curious if someone else has this issue:
My location using GPS, High Accuracy or Device Sensors is consistently off by several miles several times a week. Coincidentally, it likes to stick me to the same location that's along my commute to work. It does not update or change from this location.
If I select Battery Saving, it updates and is correct. I assume since this doesn't use the GPS receiver, which may be the source of my pain.
If I go back to the other modes, it goes back to the erroneous location. Recalibrating doesn't seem to help as this may fix the compass, but my location is still wrong. This happens every couple days, not all the time, but it is the same location it likes to stick me to, as if it's offset by my current location (since that location is work and that's the same daily then it makes sense the offset location is always the same.)
I don't know how to resolve that or discern a cause. And of course, if you don't use High Accuracy, most everything is designed to complain over and over again that you're in the wrong mode. You can imagine this make getting a Lyft or Uber a bit of a pain and interferes with Smart Locations. Anyone have a similar experience?

I'm having some issues I don't know if there is a fix I remember you use to be able to flash a file back when I had galaxy s5 to make the GPS more accurate
i have some problems with my gps too... it's totally unaccurate, can't track my position fast enough while i'm driving... but truth to be told, i haven't looked into it enough to say if it's fixable or not. last time i tried Here maps it was pretty much unusable...
