The GPS will find and get a fix on anywhere from 5 - 9 satellites in 3 or 4 seconds but will not get a lock for anywhere from 4 to 20 minutes or sometimes I give up after about 45 minutes. I have read these forums until I'm half blind and have replaced the gps.conf file in /system/etc about three times with improvements/modifications suggested by others. And still the GPS will not get a lock most of the time. On a couple of occasions it locked on in a mater of a few seconds, but that's rare.
Could this be a bug or is there some setting I'm not aware of? A couple of threads have said the com port needs to have the right address, but I cannot find any com port references on my phone using root explorer. I did a google search and could not find any GPS/com port settings.

It all depends on what rom, kernel, radio, ril you are running. Sometimes it's as simple as matching the radio to the correct ril file. Or other times, it can be a kernel issue.
So basically, for now are you rooted? List what rom you are using, current radio and ril file. Also list which kernel you are using.
I have also recently learned as well that the superuser has a factor as well if you are rooted.
I'm using the ARHD 3.6.2 XE ROM and the recommended radio which is 10.58.9035.00P_10.15.9035.02_2. The kernel is 2.6.35.14-sensation-faux123-v0.2.1 (all from Mike1986). I did some testing a few days ago and found that superuser Ver. 3.05 did indeed interfere with the GPS. SU has been updated to V 3.06 and I haven't had any issues with FC or permissions since, but I have not tried testing to see if it still interferes with GPS.

LOL I thought your nick seemed familiar. I remember you testing out that SU issue.
First off, have you tried different kernels at this point? Go back to a htc kernel and try the gps, then if you get the same results try different gps.conf files.
I have been testing out different kernels on an agps beta file test. Try the fix, make sure on the /system/etc, there is no suplroot file in there and push the gps.conf. I'll attach a good gps.conf for you to push over from this thread http://forum.xda-developers.com/showthread.php?t=1262652.
Use the "generic" one first. You can either push the file in the zip or flash it in recovery.
Here is an example of the frustration. I took this screenshot just a few minutes ago outside under a clear, cloudless sky. The GPS found and fixed on 8 satellites in about 4 seconds. There was no lock after 15 minutes so I quit and came inside. With that many satellites and that pattern I should have had a good lock as soon as they came up.

Actually that is the gps.conf file I am using now. I installed it a few days ago. There is no doubt it helps find and fix the satellites in quick time and is a vast improvement over over the stock, but I still have the lock-on problem.
Any suggestions on which kernel to try?
P.S. Told you I had been reading these forums

I would say try the stock htc kernel first but if you want to just jump into another kernel try the bricked ones. I personally didn't have great luck with the faux kernels at all. Shame because it was really good. Anyways, here's the link to the bricked. Also make sure you don't have that suplrootcert in the system/etc folder either.

The suplcert root is not required. In my beta testing, I tried with and without and in my testing, I ran it without it. You can just move it to your sd card for back up if you want to revert back to it.
But I never use it and it is optional. It's supposed to connect to the servers quicker, but it never did in my testing.
Wow, this is weird. I installed the bricked kernel in your link and guess what - the GPS came right up. The bad news is WiFI did not. I looked at settings -> wireless & networks and the first thing on the list is Airplane mode and it is flashing on and off. I can get wifi to work for about 30 seconds then airplane mode cuts it off. Ever seen anything like this? That is really strange.
Just found out your link is for a CM7 ROM. I'll try something else.

Well at least you know now that the kernel can be the cause of your gps probs. You just have to check which kernel combo works for your setup.

Everytime I flash a new ROM 9/10 times my GPS won't lock the first time I use it. MY FIX: I go to settings>applications>maps> and clear cache, then reboot. When I open navigation it locks in less than 10 seconds 100% time. Try it before a new kernel or radio, it's easy and almost always effective.

i don't have gps icon in the status bar, and gps can't get any locking at all. it worked once before i flashed a new rom a few days ago, now it just doesn't seem to work anymore. is the gps module broken? i tried reflashing the radios and different roms, nothing worked.

I had something similar to you but I did see the flashing GPS icon, but it just wouldn't lock. Like in GPS test app it would not see any satellites. It didn't matter what ROM i was on, or even if I tried to flash a backup where the gps worked, it wouldn't change anything. I tried the before mentioned re flashing the radio and it didn't find it on my sd just like you, so what I did was redid step 5 in the hack kit. This essentially does the same thing that you were trying to do with the PCIMG.zip file. Give it a shot it should be easy if you rooted with the hack kit, just plug your phone in with debugging enabled, set as charge only, change the directory (cd) to wherever you saved the hack kit, and then run the sh hackerize-ace.sh setup-radio, then run the sh hackerize-ace install-radio(for me because I was on a mac I had to use the sh hackerize-ace.sh install radio), then follow the instructions in HBOOT. It worked for me when nothing else would.

I have been having this exact problem, no matter what ROM I use GPS will not see any satellites. I have tried everything, including redoing step 5 of the hack kit. Is going back to factory settings my last resort? I would really rather not have to do that, but I will if it's the only thing that will fix GPS.

I thought my gps was back to normal but today on the road it was hard to get a lock again. It would see like 3-5 satellites, but wouldn't obtain the lock. I don't know what to do now, after re flashing the radio from the hack kit, I have a feeling one of the roms is breaking the gps for some of us. My guess is that it is changing something in the gps module which cannot be fixed easily. Will be looking forward to a real fix for this as gps is something I really need.

Update: after a few days my gps seems back to normal, I can even get a lock to 30m inside. Hopefully it stays this way. The best answer for me is redoing step 5 of the hack kit. And for me it was getting a weak signal at first but after a few days it seems to have stabilized.

OK, so I've dug around the forums and have yet to really find anyone who had a similar issue and wasn't able to fix it with either FasterFix or GPSStatus so thought I'd start a new thread. If anyone knows this answer and knows it's in another thread then let me know and I'll shut this one down...
Anyways, the issue in a nutshell is that Maps refuses to work without "Wireless Networks" being checked (it throws up an error that tells me to turn on My Locations or to turn on either "Wireless Networks" or "GPS satellites" even though GPS sats is checked in the settings) and even then the accuracy is horrible (on tower-based, which is more or less to be expected since it's a triangulation, I believe), Navigation/Locations will both get a location but it appears to be "Wireless Network" based, GPSStatus shows a max of only 3/3 sats even outside on a clear day but no other app sees those even those 3 sats. I basically think my GPS chip is locked up. (Is that even possible?)
The GPS issues started one night on CoreDroid's V5.0 after working for quite some time on CD's various builds, including working on 5.0, so I flashed up to 5.1 and still no-go. Wiped everything, reflashed 5.1 and still nothing. Moved over to RCMixHD 5.9 and it still acts up. It used to be that I could uncheck "Wireless Networks" and it would just bounce off of the GPS sats but now nothing seems to see the chip. I've wiped everything, reflashed numerous times, flashed a new radio (the latest Mar leaked GB radio), gone inside, outside, around the house, around the town, etc etc etc, cleared the Maps cache, uninstalled/reinstalled Maps, reinstalled Locations several times, reset the GPS state with GPS Status, redownloaded the GPS data w/ GPS Status, changed out the gps.spade.so file in CoreDroid 5.0/1 with one from the Inspire Dev Forum (I think, may have been General) that modded files based off of FasterFix files that were supposed to fix the GPS if FasterFix doesnt (the files worked for a whole one test...then everything quit working right again) and I've reset the NTP to North America's server via FasterFix and STILL nothing. I'm getting rather frustrated at this point and any help would be appreciated. Thanks guys!
How about flashing back to stock Rom?
Sent from my calculator
What would the advantage be? I mean I've already flashed different ROMs and gotten the same issue so part of me doesn't care to flash another couple of times but another part of me wonders why it'd help any since it's just going to be overwritten when I flash back to RC or any other custom. Will flashing to stock somehow reset the GPS. I know flashing to stock is generally one of the first suggestions but I've always wondered how it actually helps. Guess I'm off to hunt down the stock on my computer while I wonder lol...thanks
Did you use RUU to get back to stock Rom and radio? RUU does more than just flash the Rom. It flashes the radio to stock. Only reason I'm saying this is cause someone else had Gps issues and when they went to stock unrooted, everything worked as it should.

Do a forum search for inspire RUU. Should come up.

Awesome, thanks. I was unaware that the Inspire had an RUU. Well, most RUU's I've run across have been packaged into a program like ODIN but I think I can do the RUU manually via ADB. Hopefully they have a program out, though. Think all my stock stuff has been done via ADB and the Hack Kit so I'll dig around for an all-in-one program. Thanks!
Sadness...no such luck even on RUU stock.
Just curious, what method did you use to do this?
Is this the same one you used?

I have been having similar GPS issues on my stock Inspire. After a long HTC customer service call, I was advised to do a factory reset on the phone. Voila, the problem appears to be solved. I now get 8 or 9 satellites and lock in about 30 seconds. Also, after this reset, my battery life is much better. So, I am not sure what bug I eliminated in the factory reset, but I accomplished something. What would affect both battery and GPS? I know this is not the same as for a rooted phone, but perhaps there is some connection. By the way, just what SNR do users with solid GPS performance get on GPS Test? I never get SNR over 25 on any satellite, whether indoors or out...
HtcOmega,
I helped another person with an inspire, so maybe it might work for you too, Try the link in my sig and see if replacing the gps.conf with one of mine may help you. It has been very successful so far, it might help with your dilema as well. And if your going to ask whats different about mine then fasterfix app, the answer is alot.
Let me know.

I was having the same issue as HtcOmega and decided check out your link. I must say that my GPS is working as it should now. Takes at most 30 seconds for a lock without the case on. I flashed the north america zip instead of choosing the north east version. Is there any reason why you wanted people to choose their specific region?
Primarily the reason is I broke up the USA into 6 regions and made a script for 62+ individual countries because I am not using the generic ntp servers from the pool, these are ntp servers specifically for that location, and by narrowing down the location and not using a general ntp it should make lock times faster. If you read the thread for the most part quick reading you will see that the NA script is made primarily for people who travel to many places frequently and do not want to keep changing scripts, as well as people in the common wealth countries would use the NA script.
I am currently testing out 1.2 with a handful of beta testers to see if the new script can be a little more consistent, there are new commands in the new script, which is phase one at least for the HD2 since the HD2 is a prt and lacks the support for true agps.
OK after doing some research and testing on over 10 devices I have came up with this MOD , that has been working for me for 2 days now. This should work on most devices. We all no Samsungs GPS hardware is not the greatest. Some with the S3 have no issues some where in the same boat as me. For myself I could never get a lock in navigation, if I could it would take 10 min up to 30 . If I ever got a lock ,it dropped signal frequently or was inaccurate, so much that it was no of use. Now on maps it would eventually show my position but it would be off , for example, show me on the next street or on the other side of the highway. So If you find yourself in this situation feel free to give it a try.
★★★★★★★★★★★★★★★★★★
You need to be rooted to be able to grant R/W capabilities. To be safe , always make a nandroid backup and back up the original file you are replacing. My self or XDA are not responsible for any malfunction to your device or anything else that may occur, while hacking your phone.
★★★★★★★★★★★★★★★★★★
1) Download new gps.conf file>>>
http://db.tt/5xvFneRt
2) Replace it in /ect . Rename the original one from .conf to .bak. using a file explorer with R/W enabled , so yes you have to be rooted!
3) Download GPS toolbox https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
4) Reboot.
5) Enable standalone GPS and Google services NOT Verizon services.
6) Open GPS status select options/tools/reset . Then options/ tools/download
7) Reboot
8) Open GPS status and wait for lock . Mine took 5 min a friends took 3. Then open up navigation .
9) Profit
★★NOTES★★
Always enable standalone GPS and Google location services ,FIRST! Then open up GPS toolbox to get a lock. The first time you do this it might take up to 10 to 15 min based on your location. After getting a lock threw the app, then open up navigation and you should be good to go. After using this yesterday I'm locking on in under 5 sec with 9-15 sat locked on. If you have bit used your GPS in a while, open app and reset and download again , then reboot. Then wait for lock threw app and your back on track.
Hope this helps a few and I will be updating this when I finish implementing other things.

just saying, but shouldn't you go get your phone replaced, have verizon check it, if you have gps issues? many GS3 owners including me have zero issues with GPS. I did have GPS issues with 3rd party roms, synergy and clean both. once back to stock rooted, no problem.
The gps on the S3 is the quickest and most reliable i've had the pleasure of using, out of the box. I can't express enough how impressed I was by this, because i've become accustomed to having to fix it to make it work properly, and have done so for a variety of androids for my random co-workers I meet on the road.
That said, if people are having issues - and lets be real here, once you start flashing stuff anything can happen - it's good to see people diving in to work on the problems.
To that end, OP (or anyone else interested), here is a thread with a very detailed explanation of what I did to fix gps for another device:
http://forum.xda-developers.com/showthread.php?p=16822068
...which may be of some value to read through in your research for this issue.
Please forgive the dead links, I was away from dev for a while and didn't realize goo went down and lost what I had there. I am working with another forum member to get my works hosted again.
Meantime, the text of the gps.conf file is in code blocks in the op of the thread I linked, so in this particular case the dead links shouldn't be a problem.
Hope this helps a bit.
I'm beginning to think it has something to do with Google maps. Downloaded map quest and it locks on quickly.

Hello,
Acouple days ago my GPS decided to stop working. I can no longer get a GPS fix on my phone, even if Maps says it has a fix its not accurate. (shows me driving on 3-4 roads over from where I actually am)
I have tried tightening the screws as outlined here to NO effect. http://forum.xda-developers.com/showthread.php?t=2201668
And the fix listed here
And finally manually editing the GPS.CONF file to include more specific NTP servers for the US, after that didnt work I tried an APP called FasterGPS that did more of less the same thing I did. My GPS did work for a short period after using FasterGPS but now has returned to not working at all.

Maybe something software related got messed up. I noticed that you are on Build 4.0.4 VRALF2. That is quite a few versions from the latest. Maybe factory resetting and updating to the latest version out would help?

That was my next step.
However Ive been thinking of just flashing CM10.1 for awhile now so I might just do that.
Just want to see if I can get this resolved without the need to reflash.
Hallo everyone,
after many years of use without problems and with the Stock Android OS my GPS stopped working. I noticed that using first Google Maps, then I had the confirmation using the app "GPS Status" (Screenshot here: https://www.dropbox.com/s/5xikt3yd4fz4sen/Screenshot_20190113-135600.png?dl=0).
I tried to use the "Hard Paper" fix under the GPS contatcs, but It didn't change anything.
Any tipps?
Update: I changed the Backcover (inclusive GPS antenna) with a new one, but It didn´t change anything. Could maybe be a software problem?
The contacts may be busted. Neither NFC or GPS work on my N5 anymore. The contacts failed after the years of use/abuse. I didn't dig much deeper into fixing it than just confirming the problem as I only use my N5 as my snowboarding phone/media player.
Thanks for your answer. I checked the contacts of the Motherboard too, but the seems completely fine. I didn't had any Problem with the NFC, but the GPS still doent work. I have done a factory reset of the whole OS, hoping it was a software problem, but there's no difference and the GPS still doesn't work.
I still want find the cause of this. Any other tipps?
Maybe the gps.conf file is broken (it usually happens when you install a custom rom but maybe it happened on stock aswell)
Try to replace your gps.conf file with this one here. (need to be rooted)

Thanks for your tipp.
I first installed Lineage 14.1 (the OS works really well in comparison to the old Stock Rom) but the GPS still didn't work. So I tried first to install the new gps.conf via this guide, with no change. Then I tried the the app TopNTP, seems that it doens't work. So I gave a change to another App, GPS Fix/Optimzer, but even if it install of the .inf file succeded, the GPS don't work.
Im running out of ideas an hoping for a miracle. :angel:
Sorry, I thought that with the Lineage OS installation there was an automatic root of the phone. Of course I was wrong, and that's why the TopNTP and GPS Fix/Optimizer didn't work.
I rooted the phone right now, and tested the Apps in order to fix the GPS Issues, sadly without much success.
I tried different combinations with TopNTP, then used the GPS Fix/Optimizer standard options for my country. With both the Phone GPS can't reach a better accuracy of 1,5 Km. I don't remember if before was better, but the GPS is still not usable.
Still looking for help, every tipp is welcome! :good:
