[Q] [Samsung i9506] GPS bug - drops out regularly in morning - Galaxy S 4 Q&A, Help & Troubleshooting

I have a strange bug on my Samsung Galaxy S4 i9506 and am hoping other people here have experienced and are able to solve the following:
I use my phone extensively for navigation whilst driving. I use Sygic as my sat nav app.
I have noticed that the location on the navigation app has been freezing at the location for a period of 2-10 minutes and then regains location for a minute before freezing at the last location again. This seems to happen every morning on my morning commute to work, however 95% of the time it works flawlessly on my return trip home!
I have tried using other nav apps such as Navigon and even Google Maps to isolate the nav app as the problem but they also seen to experience the problem. GPS Toolbox also loses location and regains when used.
I have found that if I exit my nav app and then re-enter it, the location appears to update for up to a minute before losing gps connectivity again!
I am running stock Android 4.4.2, Baseband version: I9506XXUCNF3, build number: KOT49H.I9506XXUCNH4. Phone is NOT rooted.
I am based in Brisbane, Australia if is a location-based issue?
I have even tried doing a factory-reset and reinstalled only the apps I use and the problem still appears!
I would really appreciate it if anyone could help here with useful suggestions and solutions as this has really been frustrating me for the past couple of months and searching for help!

[Q] GPS doesn't work after flashing CM11

So I recently flashed CM11 on my LG G2 (Verizon). After some initial troubles, I managed to get everything working just fine, except for the GPS. Even when I turn on high accuracy location services, the GPS will place me within a few hundred feet of my location at best when I'm not connected to WiFi. If I try using maps to navigate somewhere, all I'll just get a GPS lost notification soon after I start it, and then my location will randomly hop around as I drive within a few thousand feet of my actual location. I'll never actually get a GPS lock or have it be accurate enough to give me directions. This all worked perfectly fine on stock, so it can't be a hardware issue of any kind. Has anyone experienced a similar issue or have any idea how I may go about solving this?
Thank you
bump
I'm having a similar, if not the same issue. New D802 Intl LG G2, GPS was fine in stock.
I installed CM11 Snapshot M11 and GAPPS, and Google Maps is unable to use the GPS. Interestingly a 3rd-party apps such as the popular "GPS Status" and Co-Pilot apps work fine.
When I load Google Maps and it sits there looking for a location, the location icon doesn't appear in the notification bar. However when I use "GPS Status" the notification icon appears instantly and gets a lock quite quickly.
I notice a few mentions of GPS issues on the CM11 bug tracker but they say resolved -- https://jira.cyanogenmod.org/browse/NIGHTLIES-199
I just tried the latest nightly 20141022 (dirty update), but still the same issue.
I only just spent the necessary couple of hours to get the phone setup so I'm a little unwilling to do it again until the weekend.

I have the same problem. I have a rooted SM-G530H which worked fine locking onto GPS until this month (August). Lately, it takes a long time to lock on to GPS with Waze. I've tried factory reset but still the GPS lock takes so long, even on a clear and sunny day. I have GPS lock installed but don't know if it really speeds up GPS lock. I also noticed that when using Ulysse Speedometer pro, the GPS is ok (sort of) and can tell my car speed via GPS. If I have waze running in the background, I can hear it also locking to the GPS and giving me turn by turn directions. But if I return to waze as the main program, the GPS lock will be broken and will stay broken. Then if I return to Ulysse again, GPS lock will be restored after several seconds, and waze (in the background) will also lock and resume giving me turn-by-turn instructions again. So I don't know if Waze is the problem. But GPS lock really takes a long time compared to the previous month.

Reading about this and searching around, I found that somebody suggested going into Airplane mode and that doing it solved his gps problems. I tried it and all the times that I've used it in airplane mode it hasn't lost gps fix once. I used primarily for running and jogging applications, so I don't need internet or data when doing it.
Hope this helps!!!

Hi sickofgalaxy! I use gps for my running apps, Nike+ and Adidas Run and Train, most of the time. When I am home I'am connected to my home wifi and before leaving home on a run I go into airplane mode. Once in airplane mode I run GPS Status App and it locks into the satellites very quickly, I then start walking to the track where I jog; once there I start Adidas Run and Train App and use it without a problem.
Hope this helps!

I've the same problem...

GPS service stops after a random time

I have a P1640 TN7 and used it as my sat-nav device while I was in the UK the past few weeks. I used co-pilot as the offline software, which worked wonders, but the GPS kept dropping anywhere between 15mins and 60 minutes. Sometimes I could cycle location services off/on and resume the sat-nav, but most other times I had to reboot the tablet.
I changed all settings, but the GPS still dropped after a short time. It wasn't just co-pilot that lost GPS, but gps-status and G-maps also couldn't pickup a location until it was rebooted. I recently re-installed 4.4.2 stock just before the holiday.
Any ideas as to why GPS service decided to freeze up?
I have the same problem, GPS is randomly dropping signal and device cant be found. Rooted tablet.

Have you experienced GPS lock issues?

I've found that sometimes I can't get a GPS lock and have to restart the phone to get one. It makes using Waze a pain.
No.

I'm having the same issue. Annoying.
Never had any issues. In fact this is the first phone in a while that does a pretty decent job of it
on XT1575
checking my gps using "gps status" app (https://play.google.com/store/apps/details?id=com.cochibo.gpsstatus&hl=en)
GPS is on, able to see 20 satellites. I have a lock on 0 / 20.
No GPS locked quickly
You been outside or inside house?
Outside
I've had to toggle from the settings to get it to work without rebooting.

I've never had an issue with my GPS. You should go to settings> location and see if you phone is in high accuracy mode. Both my moto X's came with battery save mode as the default.
Tried.
I've also factory restored. I will try again this evening.

It was already there. I use Waze every day. Sometimes it won't lock. I have to toggle GPS to get it to work again.
I think it might be a Waze problem. When it happens to me I just close Waze, start GPS Status app, and restart Waze with both running, and it locks right away. No other apps have this problem. Waze still hasn't fixed the semi-random shutdowns that it does in the past 2 years of use, so I don't expect a fix for this GPS problem either.
I never had the problem with my 1+1. It was always immediate. Waze hasn't shut down on me with either phone.
Random GPS lost fix during Waze navigation - suddenly Waze reports GPS lost fix - only happened to my with my Sony Xperia Z3. It happens when I put the phone on my lap - I guess putting it in a mount close to the windshield will improve this issue.
Still very disappointing as OPO, Meizu and other cheap chines phones never gave me this issue.
GPS lost
I'm experiencing the same issues since the beginning. It happens in all GPS applications. Not only in Waze.
I'm using Endomondo to track my runs. I have gaps of several kilometers. Sometimes, the lock won't come on without switching the GPS off and on.
The same issue for Pokemon Go.
I returned my phone and they replaced the mainboard.
That didn't fix the problem!
Did anyone fixed the problem?
I frequently get a message in Waze about no GPS. Typically if I kill Waze and restart then I get the GPS signal.
I only see GPS problems in Waze.
I got this all the time in Dirty Unicorns 10.6, when I switched ROM's I had no more issues.
I'm still on stock image. Not rooted yet.
I applied
Code:
fastboot erase modemst1
fastboot erase modemst2
which is suggested for Moto X Play (http://forum.xda-developers.com/moto-x-play/help/gps-issues-x-play-t3248283) and Moto G (http://forum.xda-developers.com/mot...-gps-custom-rom-backup-special-t2909768/page3).
Simioni (post 15 http://forum.xda-developers.com/moto-x-play/help/gps-issues-x-play-t3248283/page2) suggests it's related to 3G connection.
I will do some trials.
If your rooted try FasterGPS, if not GPS Status & Toolbox can update aGPS info... Might help too.
I went for another run today and the part that was missing was now tracked perfect.
"Erase modemst" seems to fix my problem.

GPS not locking on after 5.1.1 update

After updating to 5.1.1, the GPS on my N910G is useless for navigation. If I am still, it can pinpoint my location on "High Accuracy" setting but when I'm moving i.e. when using navigation, it never locks on. Setting location to "GPS Only" does not help either. Does anyone else have this issue?
I have a similar issue. After a reboot, the GPS locks for 2-3 minutes, and then stops locking until next reboot.
I just posted a thread about this!
I also can't get a lock after the update.
I tried so many things and I gave up , everything was fine before
I had terrible fix issues with my GPS. I switched from wanamlite rom to sweet rom, now my GPS works again!
