If this helps you I would appreciate it if you hit the "Thanks" button on this post.

I can finally 100% confirm that the GPS signal lost issues we have is software related.

The best workaround I have found for this is to:

Root your phone using Kingo or whatever root method you prefer

install KNOXRAID

[MENTION=4701028]drakeymcmb[/MENTION] made this ROM, so you know it's going to work.

***WARNING TO ALL USERS***

This thread is not a "Best ROM" thread and will NOT be treated like one! Possibly any ROM that's "rigged" will fix the GPS issues, but this is currently the only one I have found that works right every time.

UPDATE: I wanted to add that if you have a AT&T ROM installed (may work on other ROMs, but definitely ask drakeymcmb before trying anything with a different ROM), Drakeymcmb has a fix here I'm quoting.

good ****. got lost a few times because of the gps.
[AT&T Galaxy Note 3 General] MonkeyThumper:
I will 2nd this "fix"...

I actually rooted/SS/ROMed my phone a few days ago because I saw that it did possibly fix the GPS problem.

I was having the issue where GPS would disconnect when changing cell towers, or if I plugged/unplugged the power from the phone. I could reproduce it very easily.

So, I installed X-Note, and did some testing yesterday, and did not have a single GPS drop in over two hours of testing. I was also able to plug/unplug the power without losing GPS signal. On the way back to work this morning, I switched back to my stock ROM slot in SS, and the issue was back.

I do NOT know if the issue is fixed with any other ROMs. I have only tried X-Note at this point.

Would be great to know what is actually causing the issue with the stock software. Samsung still plays dumb about the problem, acting like they have never heard about it from anyone. I was very close to getting a replacement from AT&T under warranty, but just hadn't gotten around to it yet. May still do that if I get the urge/time to put everything back to stock. I just don't want to end up getting a "refurb" from them. I've gotten one on a past phone, and it was a piece of crap that had more problems than the one I turned in. I'm not sure how much testing they actually do on a refurb phone before thinking it is ok to give out to someone else.
[AT&T Galaxy Note 3 General] wiser212:
I exchanged my phone 4 times with AT&T before I accepted a replacement. I complained each time about their lack of testing. The 4th one they sent was brand new. If you get a chappy phone, keep requesting replacements.
[AT&T Galaxy Note 3 General] MonkeyThumper:
Your use of "chappy" reminded me of this:
[AT&T Galaxy Note 3 General] gold3ndrag0n:
I too can confirm it's some sort of a software/app conflict problem. This is what I posted on AT&T's forum:

Like you guys I have been doing the same thing. After wipe it seems to work fine, and I do suspect it's a software issue. I was actually in the process of writing an update here last night, as I was writing I decided to check it one more time to be absolutely sure I'd gotten rid of the problem when it happened again.

At the time I suspected the Flipboard widget that's preinstalled on our homescreen as that was the last app I started up before it happened. So then I wiped my phone a second time last night to test out Flipboard, but to my dismay the GPS continued to work perfectly even after I had signed in to the widget. Then I suspected GSam as that was the app I set up prior to Flipboard. So I left GSam uninstalled since the wipe last night, everything was still working until a few hours ago. I was going to drop by here and give an update when I thought, okay one last test... then boom we're back to square one.

It has to be some sort of software issue as all 3 of us have noticed, a factory wipe without installing apps/backup restore works but after we install our apps and use it for a day or so it bugs out again. But I can't think of what might be causing it, what app could affect the GPS chip like that? Plugging/unplugging normally has NOTHING to do with the GPS, so why is it causing it to shutdown. And the 4G LE to 4G switch too, it's on a separate radio, so how does it affect GPS? This is beyond annoying but at least we've been able to confirm with a 80-90% probability that it's not a hardware problem.

To add to that, once the problem has been triggered, even if you boot into Safe Mode it still exists. So it might even be something in the firmware itself. The only way to get rid of it is a factory reset or flash a different ROM like others have done here. Sometimes I do really HATE AT&T. Seems their ROMs are the buggiest and most untested out of the 4 major carriers and on top of that they lock our bootloader too.

[AT&T Galaxy Note 3 General] dakleenupman:
If it's software related, how do those who exchange their phones get it corrected? My assumption is they set their replacement phone up the same way they had it prior to having the GPS issues?
[AT&T Galaxy Note 3 General] gold3ndrag0n:
Being that it's software, we don't know what the trigger is. It could be any combination of things. For instance, it could need things to be done in a certain way to set it off, like say setting up the My Magazine then hitting My Story then going into Flipboard. And if it's not done in that order it won't set it off. When you reset your phone and set it back up, do you always do it in the exact same order each time? This app first then that app? This setting first then that? No, it's always in a different order.

Deduction tells us that it's software. Can't be hardware if it works right? Hardware either passes or fails, there isn't an in between. So if all of us that do a factory reset and it works until we start personalizing it, then obviously the hardware works right? And those guys that posted above about going to X-Note ROM and their GPS works correctly shows that it's not hardware right? Hardware can't choose to work with certain software and be faulty with others, that's the software's doing. The guys above aren't the only ones to have it work perfectly on X-Note either, a few others on other Note 3 GPS threads and a few on the AT&T forums have said the exact same thing, going to X-Note solves their problem.

One last thing to consider, GPS and wireless radios on our phones are different, AT&T may not have been able to test each model extensively on their ROM and Samsung may have. Take off your back cover and look at the top right corner, judging from the Note 2 that should be your GPS chip, see that number? That identifies the model of your chip, I've seen people say they have 1-4 or 1-3 or 4-4 or 2-2 and so on. Each batch with the different chips Samsung could have tested extensively to ensure their ROM works with all those chips. AT&T probably does not as they probably don't pay attention to those components because they're not the manufacturer.

Everything in this world is based on deductive reasoning, you use it whether you're a car mechanic or refrigerator repairman or computer technician or help desk or even doctors. What do you think House does? That's what most doctors do, they make an educated guess based on symptoms and if they're wrong, they've eliminated one possibility and gone on to the next until they find a cure. Deductive reasoning at work, and so is this thread.
[AT&T Galaxy Note 3 General] xfaega:
This is my thought after reading about simular problems with other brand Android phones and also some iphones. There's a technology used by some but not all phones called aGPS. What this is a gps that relies on cell tower assistance for better gps tracking. From all the simular complaints this theory is a match. Another reason I come to this conclusion is that the gps - cell - wifi - and Bluetooth are all independent components. But if you put your phone in airplane mode and try to use the gps it won't be able to lock onto your location. But other Android phones are able to do this in airplane mode. Then I tested the theory and when I enable the wifi the gps locked dead on my location. Then I turned off airplane mode and let the cell sign connect and I hit locate and it did the same thing as wifi. So some how the gps is linked to aGPS.
[AT&T Galaxy Note 3 General] Walter.White:
Alright so [MENTION=4701028]drakeymcmb[/MENTION] uploaded the fix http://www.mediafire.com/?j9tq965psemg9nv

Flash it through SS and report back.
[AT&T Galaxy Note 3 General] gold3ndrag0n:
This has NOTHING to do with A-GPS, this thread is not about the GPS taking a long time to fix, please don't convolute it. A-GPS has to do with TTFF, it doesn't switch off a GPS chip. I suggest you do a lot more reading on A-GPS and understand what it is. And read what this thread is about, or GPS chips pretty much TURN OFF when we plug/unplug the charger when we ALREADY HAVE A LOCK. And the it does the same thing when switching network from 4G LTE to 4G.

I don't know what you're talking about with your "tests" because first of all they have nothing to do with our problem discussed in this thread and second you seem confused. Let me clarify for you.

Firstly, we don't have a problem with fix or how long it takes to fix or if it even fixes at all. We all get SOLID fix, our GPS loses signal at the plug/unplug of a charger and at the change in network i.e. going from 4G LTE to 4G. Do you see why your "tests" have nothing to do with us? You see why you're confused?

Secondly, you must be confusing not getting a fix with not loading a map. Without mobile data or WiFi your favorite navigation program will be unable to LOAD A MAP, not unable to obtain a GPS fix. And without mobile data and WiFi (here's where the A-GPS part comes in) your phone is not getting A-GPS data which gives you a slower TTFF. But if you wait long enough it will eventually get a fix. Use a GPS test app so that way there's no map to be loaded and just wait in airplane mode, you'll get a fix in less than 30 seconds.

Are things clearer now? Let's not convolute this thread for people coming here seeking answers to their problematic GPS OK?
[AT&T Galaxy Note 3 General] xfaega:
I'm not confused. Loading map has nothing to do with the tracking of the gps. The gps radio relies on cell coverage.

Here read this

http://backcountrynavigator.com/using-android-gps-airplane-mode/

Anyway I hope the fix fixes the gps issue.
[AT&T Galaxy Note 3 General] Agent:
The problem is the GPS radio turns off and stays off when switching from LTE to 4G and vise versa. Doesn't really have anything to do with getting a fix on a satellite.

A bit testy are we goldendragon? Lol

Came back to edit this to say I'm still laughing 5 minutes later lol
[AT&T Galaxy Note 3 General] xfaega:
I read what you posted. When I do the test with airplane mode on I get nothing even waiting after a minute or so. That's why I was under the impression the note 3 gps is a A-GPS. Heres a screen shot I took.

There's no blue dot nor arrow. But if I turn on wifi it instantly locates my location.
[AT&T Galaxy Note 3 General] gold3ndrag0n:
Ok it's not that a phone is A-GPS or not, it's does it use it in conjuncture with GPS. Assisted GPS just means that instead of letting the GPS chip do all the work, your location data is sent to your phone over mobile data or WiFi to Assist the GPS in figuring out where you are. So without the information sent over your GPS will still work but just slower in getting a fix. That's why I linked you that article. And that's why I said you were confused in the first place, I wasn't being mean then, at least not yet anyways.

Wait longer or like I said download GPS Test and see what's going on with your GPS chip. Download it then put your phone in airplane mode then run that app. Wait and see what it says. I don't know how long is the average but my phone gets a fix in airplane mode in less than 30 seconds, but if yours doesn't get it that quickly then just wait longer. But using the GPS Test app you'll actually see the satellites and how strong the signals are, it'll let you know if your GPS is actually trying to get a fix or not. Try it with the app and see what happens.
[AT&T Galaxy Note 3 General] xfaega:
I tried the app my signal is only 22. This is where I get confused my note 2 was able to use gps in airplane mode and without cell service. It was accurate. But for what odd reason I can't even get a location lock in airplane mode on the note 3. I know it's been said it's a software issue so has any tested the gps in airplane mode to see if it is actually working?
[AT&T Galaxy Note 3 General] gold3ndrag0n:
22 what? Take a screenshot. I have and it works perfectly fine in airplane mode.

I was on the phone with tech support and we went through the entire thing. I did a total restart of the phone and reinstalled all the apps. So far so good. Worked fine on a couple of errands today.

I used Dynamic cat, realized had no gps when i needed directions. I then switched to 6.1 Dynamic cat from 7.2, still nothing. Then switched to Firecat V11, still nothing. 4 file Odined back to stock, still nothing.. can someone help ? It locks my location however as i move there is no navigation

edit: just 4 files and pit file odin back to stock, still no gps, signal lost right away. no recent physical damage to phone

I have gotten limited help from q/a and the development sections. So I guess this would be my last hope.. now phone is completely stock restore with pit and 4 files. No gps. What's interesting is the power saving gps mode seems to be able to lock my location. The high accuracy mode just gps signal lost.

I've tried many many things and yet my GPS still doesn't work at all.

I was using X-Note which had no problem, it all started when I flashed CM 11 on it.

Thinking that CM was the problem causing it, I flashed to a Note 4/S5 Themed ROM with AEL Kernel and still nothing.

Finally, I decided to flash back to Stock NH1 and yet still the problem is not rectified.

GPS Status - Does not have any satellites shown, it stays at -/- instead of something like 12/23

GPS Toolbox - Nothing even after an hour.

Tried Reset GPS then re-downloading the GPS Data.

I've also tried SchecterRocker's fix (http://xdaforums.com/showthread.php?t=2729322) and still no avail.

FIX for GPS Directions

The issue I had:

GPS somewhat got my location accurate around 10-100 meters but the compass was so wrong! When it worked rarely, still I had to either place it on a desk or hold it flat level. If I incline the phone to my viewing angle, compass starts circling wrong. But most of the time it didnt show the cardinals at all, the needle just faces somewhere and stayed that way no matter where I face or turn the phone to.

Try this out, This worked on me:

On you dialer type in this USSD *#0011#

Touch menu key > press back

Touch menu key > press key input > Q

Touch menu key > press key input > 0000

Wait for a few seconds until the screen options will change to a new list

Press on UMTS

Press on Common

Press on NV Rebuild

Press on NV Rebuild again

Press on System, Protocol, GPS, IMS

Wait for 30 seconds and then shutdown your phone

Power On phone

GPS should work fine now

Recommend to use GPS STATUS app to reset and download AGPS Data

This worked on my Unrooted, International, Stock Rom

Galaxy Note 3 N9005 LTE

. But I think it should work on all other career variants (my guess is even other Samsung Galaxy phones than the Note 3 (havent tried though))

P.S. This doesnt need Root permission or flashing anything or replacing files whatsoever. Its a hardware recalibration "kind of" thing.

All the credit goes to XinfinityoO for working this out and Stevles for posting this fix on XDA.
[AT&T Galaxy Note 3 General] Gungahlin Al:
I have got this to work fine using stock ROM, but can't get even to the second line using CM ROM. Am I missing something?

Regarding Post #1

"1. Backup the following files

/system/lib/hw/gps.default.so

/system/lib/hw/gps.goldfish.so

/system/lib/libloc_adapter.so

/system/lib/libloc_api_v02.so

/system/lib/libloc_eng.so

/system/etc/gps.conf"

Only the last 3 of those files exist for the N9005 HTLE. So I'm guessing this solution won't help for international users?

This problem has been going on since the stock upgrade to 4.4.2...

As an Ingress player, GPS is everything so this is a real pain. It is also thrashing the GPS trying to get a lock as soon as I go indoors, which kills the battery unless I manually turn off High Accuracy all the time.

The modem in my unit is marked L1 H4_2-3.

I recently got the note 3. Ran it on stock NC2 without any gps issues. When I use navigation I'll turn on location and open up Maps. I'll get a gps fix "Location set" pretty quickly, 5 to 10 secs. While using navigation, it'll stay lock without any interruptions or "gps signal lost".

Well last week I updated to rooted NJ5 and gps acted up. It will take several minutes to get a "Location set". Keep getting "GPS signal lost". Navigation was barely useable.

Yesterday I Odin back to NC2 and gps issues are gone, back to normal. Either the new NJ5 firmware, using safestrap, rooting it, deleting some bloatware, or some process of tweaking it messed up the gps. I'm thinking of trying the latest update without root to see if affects gps or not.

Next time you flash something, read the OP.

This was never meant to be a flash install.

[AT&T Galaxy Note 3 General] Stallione:
As I heard its something to do with some strange use of the magnetic sensor by the new google maps version. Apparently Note 3 Jellybean update had no such problem whatsoever. The thing is Kitkat ships "with" the newer version of the maps app preloaded. So we cant go back to the working version. Unless to install the JB rom/custom rom.

As Ive heard this is a problem for other branded phones too, HTC, LG, Sony users has said the same, whereas everyone of them run the official KitKat update.

And almost all of them who were able to revert back to the JB had got the problem solved. Come back to KitKat, problem comes back.

In my case I say again, My GPS locks correctly if not in 3-5 seconds, surely before a minute. But the compass location is so wrong. Recently confirmed the same problem with my dad's newly bought Galaxy S5 Duos.

Update: My problem kind of came back after a week or so of doing the above mentioned fix by me. Its not fully hectic like it was before. But I have to keep the phone sharply aligned horizontally to see the accurate facing direction. Cant incline the phone. Pinpoint still works fine.
[AT&T Galaxy Note 3 General] kinvid:
What kitkat version are you on? Does it take long to get a fixed gps when you turn on location and open up Maps? Do you have a stable gps fix while on navigation? Pull the battery cover and down below, it should say N900A_#3-4 or ...#2-4 or other numbers...what does your say?
