When using any version of the CM7 ie... PUR3AO5PTH3ORY V1.2.2X [AOSP/CM7] I can't get an accurate GPS lock without using WIFI. I have been all through this forum and tried all suggestions and my location is still off by a mile or so unless I use WIFI then it is right on. I have not had this problem with other ROMs so I know it is something in the ROM and not my phone. I love speed of the CM7 ROMs and the simplicity, no bloatware, but I do need a functional accurate GPS without WIFI on my phone for my job. I hope this gets fixed soon as I flash every CM7 update I see hoping this problem gets fixed. For some reason I am not allowed to post in the ROM Developers section so I hope this gets to the right people to make this fix. I have been flashing ROMs for almost 2 years now and have helped a lot of people with ROM related issues but I can't seem to figure this problem out. Please HELP!!
Have you tried the Sense rom fix yet? And as a new user, you must have more than give posts before you can post in the development section.

I concur with the GPS fix that has been posted in the thread on the development forum. I had the same issue until I tried the GPS fix.
THE GPS FIX:
-Download DroidTh3ory's 'Special' sense build, stripped down and built for this purpose alone, posted at the bottom: http://forum.xda-developers.com/showpost.php?p=16305878&postcount=1
-Turn on GPS
-Boot into Recovery
-Nandroid Backup your AOSP
-Flash Th3ory's Special build
-Reboot
-Turn on Location and Open Maps
-Wait for GPS lock. With a GPS lock, boot into recovery.
-Restore your AOSP Nandroid
-Reboot
-???
-Profit!!!
I've been having an issue where it thinks I am in Lithuania or Oklahoma instead of Maryland where I am. Seems to be a known issue with CM7, and sadly, this GPS fix only fixes the inability to get any GPS not inaccurate GPS like some of us are experiencing. I heard that turning off Mock Locations has helped some people, but it didn't do anything for me.

I created a well-received and ever-growing solution to GPS issues for the Inspire 4G and the DesireHD.
I'm wanting to determine if it works well with this device.
I believe it will and should work well with almost any Android devices. But, I don't have them to test from.
If anyone is willing to test, you can download the patch and read notes and details on http://forum.xda-developers.com/showthread.php?t=1250226 thread.
It would require backing up your existing configuration and flashing a ZIP using Clockwork Recovery. The only thing the patch does is REPLACE your GPS.CONF with a properly built one.
This can be a useful patch for anyone using custom ROMs.
Respond here to tests and successes!!!
THANK YOU!
What problem with GPS have you been experiencing? Every once in a while I lose GPS signal on longer trips and I just have to restart the map program. Very strange.
I constantly receive the "cannot get gps signal in this area" using telenav. I will be following this thread
ah I never use TeleNav so I wouldn't know...
I just need someone to test that and work with me, and I think I can port this sucker over to the Evo 3D...
Hello,
This is nothing new - this device has GPS problems with custom firmwares. However, I wanted to share my experience and thoughts and clarify a thing or two. Tried different ROMs, radios etc. with no success to get stable GPS for daily use with latest ROMs. So I discovered that GPS on older ROMs works differently than on newer ones. For example:
On CM 7.2 - GPS Status&Toolbox gets green even with one sattelite (fix/sat - 1/1) - it can get fix to 10+ sattelites but will never get a lock no matter how much time I'm waiting on it.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix. Once it gets a fix (for example 4/4) it changes to green color and gets immediate lock. This is also how it works on my Hero and usually is pretty fast.
So could this be a GPS driver/software problem in the ROM and why can't we get it to work on CM 7.2 the same way it's on 6.1?
I really want to be able to use newer, beautiful custom ROM like HomICS, AOPK, but since there is GPS problems on them I'm stuck on 6.1 or stock.
Cm 7.2 is one of the few roms were GPS actually works properly for me, I've written much about my GPS experiances in quite a few threads and some of my own threads, have a look around, they might be worth a read.

Yes, I did read some threads even yours and tried practically everything mentioned there but without any luck. I've got a few locks with CM 7.2 but it was couple of times when I first flashed it (mobile network was active (3g), however, I dont use it, ever) and the next day it would fix to 10/10 or more but without any lock.
Even today I got practically immediate locks with 6.1. in 10 to 20 seconds. Frustrating that this is not working the same way on 7.2.
How about you, in GPS Status&Toolbox, is your device fixing to satellites one by one (becoming green) without getting a lock? Or it needs couple of yellows before it gets a fix?

I have found that GPS status and toolbox doesn't fully work with the legend, mainly using the clear GPS data and for downloading a-gps data. I used quite a few different apps and basically pulled my hair out through shear frustration till I found something that seamed to actually work.
I use GPS test by Mike Lockwood from the market, this seams to work for clearing GPS data and download a-gps, but generally don't use it as my primary GPS app,I use AndroiTS GPS test free from Alessandro Bonetti also from the market, but for some reason is very hard to search for.
Personalty on my device these apps are the only 2 that give me constantly good results were all the other GPS apps I've tried didn't.

Yes, I did read your thread and tried these apps too. With AndroiTS I was getting elev azim data but no success in getting it to lock.
What about your lock time in daily use, seconds/minutes/ tens of minutes?
I use cm 7.2 (latest nightly) out in the open my lock time can be any where between a few seconds (maybe like 10 seconds) and a few minutes (2-3).

To make things a bit more complicated, after using GPS once, I have to restart the phone. Otherwise, it will not lock again. The first time it will lock in under 1 minute.
On CM 6.1, B 0.8.4, and probably stock - GPS Status&Toolbox firstly discovers sattelites (yellow), it needs at least 4 or more sattelites (yellow) to get a fix. Once it gets a fix (for example 4/4) it changes to green color and gets immediate lock. This is also how it works on my Hero and usually is pretty fast.

That's why I´m still using BlaY0´s ROM, I need GPS!
gpsfix works good for me!
I am on the brain's rom which is based on ics stock. I have a problem that most of you should be facing. My gps works great at first time I use it. It sees 8-12 satellites and locks quickly using 4-6 of them. The problem starts after I finish using it, 30 minutes later let's say. Phone enters deep sleep while I don't use it. So when I open an app that uses gps, this time gps sees 12 satellites again, but no matter what I do or how much I wait, it doesn't lock. Having wifi on makes no difference. Either clearing agps data and downloading it again, using gps status or similar apps. What does help is rebooting or switching flight mode on and off. It is like agps data or gps cache distracts gps instead of helping it. I would call it a gps deep sleep of death bug. Tweaking gps.conf file doesn't make a difference after deep sleep of death bug is encountered. I wonder if something is wrong with gps lib files.
Does anyone else have this issue or is it just me?
Have you managed to find a walkaround?
For other devices the fix was switching to an older radio or a hybrid one or changing gps lib files.
Is there a chance it is kernel related?
If anyone can help, please do.
Thank you everyone.

I used to have a note 2 a couple months ago and every AOSP/AOKP ROM that I flashed, there was issues with the GPS and the navigation didn't work. I am currently running an s4 on the latest stock ota and there is no root method yet, and I'm sure there won't be a boot loader unlock method for it. So I'm considering going back to a note 2. I was just wondering if the GPS issues had been fixed? Thanks guys!

I had that problem after flashing Carbon. I made a nandroid of Carbon, restored my fully functional JellyBeans' nandroid and booted into it, got GPS lock, went back into recovery and restored Carbon, rebooted and got GPS immediately. No GPS problems since.
Yeah I remember being able to get a lock after running GPS in a touchwiz ROM, but I was wondering if anyone had ever gotten a fix for the entire issue. I know GPS works on the S III for AOSP ROMs. Just curious. Thanks guys!

I have not had that problem in a long time. I don't even think it was a problem for everybody.
After rooting I cant get a lock indoors.
Before rooting it could almost tell me which room I was in.
Outdoors its fine.
The compass is another story.
In vehicles the compass is WAY OFF, but indoors or out of the car its fine. :screwy:
Looking for a fix as well
i have tried so many ROMs to get this GPS working and nothing has done the trick, not even a TouchWiz based ROM. I flashed 'clean rom' yesterday from CM11 (which i miss) so I could have gps for my holiday travels but it gave me not a drop of connection. I might as well just go back to CM since it's not working...
I have been searching Google all morning for a fix with no solutions.
It is a well known issue for GPS to not work in AOSP roms. Always before you flash CM/AOKP or any AOSP rom you MUST get a GPS lock in a stock based ROM, then boot into recovery and flash the AOSP Rom. Should fix it, every time. Then you should be able to jump between any AOSP Roms with no issues.

If you are having trouble getting a lock even in the stock TW rom, try downloading this app... https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
Install it, open it, you will find a setting in the menu called "clear a-gps state". That has fixed it for me in the past.

This has been the most persistent bug for me just as with the OP. This app was unable to fix my lock problem and I've flashed a couple of times to get a lock in CleanROM, a stock based ROM, and then overlayed my Nifilim on top. Fully clean wipes each time but no luck.

This isn't unusual as a compass is always affected by close proximity to large metal masses (your car) and to other field generators (power lines, antennae, etc.). You'll see the same behavior in physical compasses so don't break a sweat trying to correct firmware for this behavior.
The GPS problem is another story, of course.
Hey guys, ever since flashing a custom ROM onto my Verizon GS4, I've had issue with getting my phone's location. Given the location options on 4.4.3, the phone is able to get a rough location on the High Accuracy setting but can't do anything under Device Alone. As such, I'm pretty sure it's the GPS having issues. Others have had compass problems with the ROM I'm currently on, but everyone seems to be able to get a GPS lock when I can't. I've done a dirty flash, a clean flash, and even redownloaded the .zips from other locations in case the file was bad, but nothing has solved my problem. I use my phone's location settings for a variety of apps, so I'd really like to get it working again. Does anyone know of diagnostics I could perform? My hope is that it's just a software issue, and that I didn't do any permanent damage to the hardware. Thanks for the help!
(also, I'm posting here because I'm new to the forum and can't post in the developer threads yet)
Try faster fix in the play store. I've used it with several roms on several phones and it is very good

I looked up the fix you're talking about. Others seem to have had success through the gps status apps available on the playstore. Unfortunately, they didn't have any effect on my phone. I'm still stuck at searching for GPS on any app that uses it. Those who had success seem to have had it with a ROM that originally worked, but lost the ability to successfully connect. My issue seems to be in the ROM itself, or at least that's what makes sense to me. Thanks for the advice and trying to help.

I have tried faster GPS (running 4.4.4, so faster fix is a no-no) with no success. It replaces the file detailing GPS information and the like, but I'm still stuck searching for GPS permanently.
