I'm on NottachTrix. No OS, firmware changes were made to cause this issue. No new apps. It just started on its own.
I've had similar issues twice before. First time it was fixed with a Google Maps update, second time it was fixed by turning off "use wireless networks" under location.
Neither fix worked this time (Maps were out of date).
Symptoms are like this:
With "use wireless networks" OFF GPS not able to lock in at all. Been testing it for hours. With "use wireless networks" it gets within about a 1000 feet but never locks in.
In the past even if Maps was not able to lock in, Navigation did. Now its seems to be having issues too.
I tried GPS status, cleared A-GPS data. I've tried changing the radio. I was on N_01.77.30P originally. GPS status was able to find 6 satellites but not lock into any, I Flashed N_01.77.37P, no luck, was not able to find a sat in 5 min test. Flashed N_01.77.36P, able to find 3 sats not lock in. Tried to re-flash N_01.77.30P but it gives me an Install aborted message (can't downgrade that far)?
Any suggestions?
I dont see how it can be related to the ROM as it worked perfectly fine before so i did not try complete wipes or factory resets, i dont this they would help.
I have also tried using the libnmea.so from:

I would try 3 things... first wipe dalvik cache and then check gps, reinstall rom without wipe and see if that helps. If it doesn't then I would do a full system wipe and install a fresh version of your rom and see where that takes you. Software can become corrupted even when we change nothing.
I recently ran into the same problem with GPS not locking on my Atrix. Here's how I solved it after trying the things you mentioned which didn't work:
Turned out the antenna contacts were loose. After opening the phone, I disconnected the antenna connector from the main board. Then pulled out the antenna cable from the silver clip. There is a third contact point on the other end of the antenna (opposite end from the connector) that is bent up to touch the antenna. This contact had bent back down over time. I bent this back up (very gently) to make sure it made solid contact. I also 'tighted' the silver clip contact by pinching it slightly before re-inserting the antenna cable. Then I re-connected the main connector. I also cleaned dust buildup. Closed phone and powered up. GPS now consistently locks within 10s with 3-6m accuracy! (Note: Radio is 38P running Epinter's 10.1 Rom 072013 build)
I solved this problem by replacing the gps.conf on this ( Only change location on yours)

I can never get my GPS reliably. I have tried various DCD roms and various Radio versions. Currently i am running DCD 3.1.2 and Radio 3.39.10
When i run my applications such as GPs viewer and Visual GPs i notice that the sattelites appear for a split second and then they go away for another 10 seconds. Almost as if i cannot maintain a solid connection to the Comport. I hard reset the phone and it worked perfect, but it seems that i need to hard reset it every time to get the GPS to work.
I tried soft reset
pull the battery our for 30 seconds and back in
turn location to 911 only, reset and turn back to location on. Still no work.
I am running the standard settings of Com4 4800 and let windows manage
Any ideas?
Sorry to hear that. What phone you using? What carrier?
The GPS on my un-rooted Vibrant has been working quite well since the JI6 update. That update changed several of the dialer-accessed settings, and I haven't messed with any of them since the phone was finally working. I also didn't do the GPS Restore app because I figured why try to fix something that's not broken.
However, today, for the first time in two months, I couldn't get any locks. The GPS found a dozen satellites and showed normal signal strengths (25-40%) for the majority of them, but it kept losing and finding them, and got no locks. When I tried using Google Maps, it thought I was around Las Vegas (I'm in the Pacific NW), and the accuracy circle was probably 500 miles.
I rebooted the phone, but that didn't help. Then I decided to go into the GPS settings and found that there were two changes that I hadn't made: the Server FQDN type had switched from Auto Config to Custom, and the Server had switched from "h-slp.mnc260.mcc310.pub.3gpp" (which first appeared with JI6) to "www.spirent-lcs.com." I changed back to Auto Config, but didn't change the server, and re-booted. Then I went to the GPS Test app again and got a lock on 7 of 11 satellites in about 20 seconds with 20' accuracy.
Finally, I went back into the GPS settings: it was still set to Auto Config, but the Server had mysteriously switched back to "h-slp.mnc260.mcc310.pub.3gpp."
I had assumed that once I made a change to the GPS settings they stayed thay way unless I went back in to modify them, or I installed an update or the Samsung GPS Restore app. So, was this just some weird hiccup where my phone reverted to some old settings on its own, or what? I'm also curious to know what info is stored in the GPS Data Cache (which I've never cleared since I've had the phone)...in particular, could this be the source of the switched Server settings?
This is very odd however you'd get better help in Vibrant section tbh.
Seems like this was a problem for many people regardless of the configuration of their phone. Check out this thread:

Hey there.
I'm having some GPS problems with my Galaxy SII running Resurrection Remix rom.
It can hardly find any satellites. Most of the time it takes around 1 full minute to get 0/1 and after 2-5 minutes I have 0/2. After that, nothing else happens. I have tried installing the aGPS fix as found in here, but this doesn't help either.
What else can I do?
Thanks already!
Get GPS Status if you don't already have it. Then make sure you're outside in a clear area that has good line of sight in all directions. Also make sure you have data connectivity.
Turn data on, fire up GPS Status & go into tools/manage a-GPS state & press reset to clear cached GPS data. Then press download to get fresh data/ephemerides. Then stand there for as long as it takes until you can get a good fix/the phone 'learns' where the satellites are (can take up to 10 minutes in extreme cases).
Once you've done this, you should get a fix fairly quickly for at least a few days (and probably longer), tho once you get over a week or so, it will start to take progressively longer to get a fix as the ephemeris data ages. Simply repeat whenever the time it takes to get a fix becomes intolerable.
I've done this whenever getting a fix has taken ages, and after getting a fix even indoors has always been fast.
Edit - If this doesn't work, it's probably something funky on the rom/kernel side. I'd do a completely clean install of the rom/kernel, and if it was still not playing dice then a completely clean install of stock to possibly rule in/out a hardware issue.
I lurked and this reminded me of the fix.
To make it even clearer,
what this is doing is resetting
/etc/gpsd.conf
but not touching:
/etc/sirfgps.conf
Both are included with the ROM as far as I know.
For testing it can be useful to have Droid VNCServer. Android Screen Monitor with adb enabled over WiFi is a security risk because afaik

There's a megathread somewhere with all the different things involved with GPS. I think I may have even written a summary somewhere myself but can't seem to find it.

Hello everyone. I'm having this problem for a couple or days now. My gps takes too long to find satellites and get a fix, and it loses it constantly. I noticed this behavior is similar to what it was before I set it from "battery save" to "high precision" for the first time. I started playing a GPS based ARG called Ingress by google and my gps was erratic at first (I thought the game or gps precision were like this anyway), then I found changing gps to high precision made it perfect. It showed my exact position all the time, even when I was riding a bus or car it was literally where I was. Then all of a sudden, 2 days ago, it just won't get a fix. It moves to my position, gets a lock for a few seconds/minutes, and stays stuck there. Until it gets another lock a minute later and stays there for another minute, even on high precision.
I rooted my phone last week and flashed stock 4.4.4 KitKat and it was fine, it really started all of a sudden. I flashed BlissPop 2.2 with 5.0.2 lollipop, and the problem remains. After I changed my gps.conf to my regional configs (South america/Brasil NTP servers, ROM standard was North america) it improved a little but it still doesn't work properly (I've messed a little with gps.conf and nothing happened). I downloaded the GPS status and toolbox APP to reset and download AGPS data, nothing worked. But I noticed through it that it's always stuck on "Looking for GPS", when it finds it, it's when my position in ingress moves and gets stuck. When I go back to the GPS toolbox APP, it's " looking for GPS" again.
Moto E (Condor), XT1022 (dual sim) 5.0.2 lollipop BlissPop custom ROM (based on cyanogenmod), all stock hardware. I didn't change anything before the problem started, and a few other players had it too (though most are fine now except me and another one), any ideas?

I resolved this issue on my XT1021 running CM12.1 (5.1.1). The following is quoted from XDA member @BubuXP:
To make integrated GPS working you need to reboot in bootloader mode (hold volume down while turning on the phone), then attach the phone to the pc with the USB cable, and from the command prompt use fastboot to erase modemst1 and 2:
Code:
fastboot erase modemst1
fastboot erase modemst2
It will not erase anything tangible for the user (apparently). I did the test on a fresh install of the last nightly (20141206), flashed above a stock GPE rom. Edited by BubuXP, 08 December 2014 - 01:00 AM.

NOTE: If your GPS doesn't lock immediately, download GPS Test from the Play Store. Click "Clear AGPS" and then click "Update AGPS". Then your GPS should be working just fine
[Q] [pseudo-solved] Device occasionally loses Internet connection for WiFi & cellular
The Problem:
I recently upgraded to the Motorola Moto X Pure Edition and have got almost everything running smoothly except for one thing - every so often, (between 2 and 8 days) the device will completely lose its Internet connection for no apparent reason, displaying the little exclamation point next to either the WiFi or cellular signal strength indicators. It usually happens after transitioning between WiFi and cellular (leaving home, arriving home, etc.).
Once the device enters this state, no amount of toggling WiFi, data, or flight mode will allow the problem to be resolved. The device will simply refuse to cooperate with any type of Internet connection at all, even though it still has an IP address, as reported by the ifconfig command in the terminal. No addresses, local or otherwise, can be pinged.
Rebooting the device always brings it back. Clearing the cache and dalvik cache seems to make it last a bit longer, but this has yet to be confirmed.
Troubleshooting efforts and device configuration notes:
A web search turned up nothing at all, although two other people in the original thread on the Moto X Pure Edition Q&A forums revealed that I'm not the only one with the problem. My device is running the stock, Android M Rom, (rooted) but others have reported the same issue with a non-Motorola Android N ROM as well as on the stock un-rooted Rom.
This leads me to believe that the issue isn't Rom-specific, and may not even be device specific. With all this in mind, does anybody have any good tips for troubleshooting this? Any ideas for what could be causing it or how to fix it?
Thanks!
TL;DR? Device loses all Internet connectivity on all connections, usually after transitioning between Cellular & WiFi, on stock-rooted Rom, problem reported on stock and non-Motorola Roms as well. Software or settings conflict suspected.
Update: Hard reset; problem solved. No cause was ever uncovered. See post 7 for all the details.
Internet loss breakage Logcat
Here's the Logcat, if that helps. I tried getting a complete one, but had to cut it off after close to 45 minutes, so there still should be plenty there to go off of.
Any ideas?
Anybody? Any ideas at all? I'll even accept shots in the dark at this point. Made it a record-breaking <9 days, but the problem came back again, even with "Cellular data always active" switched off.
anything? anyone?
Ran into the issue again today, even having left WiFi manually turned off. Any ideas on this? I'll even take shots in the dark. Anything short of hard resetting and reinstalling apps & reinstating settings one-by-one.
Internet dropped out again...
Had the issue again today, but this time caught it "as-it-happens" (as I have only once before). This time, I woke the phone up and saw the exclamation point over the WiFi signal strength indicator, but was still able to use the LTE data connection. Resetting the cellular radio put a stop to that as well.
Any ideas at all? I'm taking complete and total shots in the dark at this point too.
Still losing Internet connection on WiFi, then cellular as well
Same deal again today. Any ideas at all? Anything I can do short of pulling the plug and hard resetting?
Hard reset; fixed
Well, I ultimately pulled the trigger and hard reset the device. The problem appears to have permanently vanished, but we will unfortunately never know its cause.
