GPS locking time - my suggestion - Samsung Galaxy Nexus

Hi all,
after upgrading to JB 4.1.1, my GPS performance was terrible.
I tried every post available on different forums doing:
Flashed 4 ROMS - didn't help
edited and swapped 4 gps.conf files
eventually one thing made the difference.
I unmarked the "Google's location service" under the Location services settings.
now the GPS is locking in 5 sec.
I hope it will help you all.

The reason why the GPS isn't working well is because Google pushed out some bad A-GPS data, not necessarily related to you flashing 4.1.1. It seems to be fixing itself now, and you should be able to re-enable Google location services. Especially because the location services is required for many apps to get your location, such as Google Now.

Unable to fix satellites for GPS

I've tried a bunch of things from the GPS tweaks provided in the sticky (To help reduce the lag) and also hard resetting twice. I'm still unable to fix onto a single satellite as google maps keeps saying "Seeking GPS Satellites (0)".
After hard resetting (both times) the first thing I did was turn on 'A-GPS' and than ran 'QuickGPS' to downloaded what was needed. Right after I'll open the HTC GPSTool' to open the port before opening up Google Maps to let it run for more than 10 minutes on both hard resets yet it is still unable to lock on to a satellite. Even with the GPS off google maps is unable to triangulate me to the right position (it's always off by two streets or so). It's just very frustrating and making me wonder if it's a hardware fault. The same thing occurred when I was using the stock TMO Rom. Also on 'GPSTest' it stays at "GPS Starting Up" with just all red bars and nothing moving but the numbers on the bottom.
I'm on a T-Mobile US Touch Pro 2 flashed with EnergyRom (Genesis) (23016). I've tried both 2.1 and 2.5 and Google maps just pinpoints me to the same location (two streets off).
Any help would be great as this is my first smart phone and first time introduced into the xda world and have liked the experience thus far.
Thank You!
*Sorry if this is the wrong forum to put this in. You may move this wherever it needs to.
Did the GPS work with the stock ROM?
No, the stock rom did the same thing my current rom is doing. It's just pointing to a location two streets away nor was it able to get any satellites. :l
I used these registry settings on my stock sprint.

BTW, if I understand this correctly, you don't need to configure any ports or do anything special to use the internal gps. The only thing needed is to make sure that the location setting is turned on (the emergency locator option in Settings/Phone/[your network]/Location-Get settings.)

[Q] Nexus won't see GPS satellites

I've had the nexus toro (LTE) for 5 days now and have had issues with the GPS since the start. It simply says 'searching' all the time and will not lock. I've installed GPS status, and it shows that it rarely if every sees a satellite (one might pop up, be gray for a second, then disappear).
Here's a pic comparing my OG droid to the nexus right next to each other:

(sorry i'm not allowed to post links yet)
Anyone have any ideas? I've turned GPS on/off, reset the gps cache using GPS Status, and can't think of anything else.
I have the same problem gps locks less than 50% of the time.
Galaxy nexus s LTE.
Its the same on the GSM version. Not much you can do about it unfortunately.

I feel like a dolt because I chatted with Samsung support and they had me soft-restart which fixed the issue.

Click to expand...

Don't; that is not a solution. On my Samsung Fascinate soft restarts would help get a lock on, but shortly after the GPS would lose connection to satellites.
Having to restart your phone every time you need to use GPS is a ridiculous inconvenience. This seems to be a major flaw in the chips / radios that Samsung chooses for GPS.
i get gps locks in 2-3 seconds.works fine.
I'm glad to see others are noticing this problem. I posted a thread in another forum complaining about this:
http://www.droidforums.net/forum/ga...ssions/189067-problem-nexus-locating-gps.html
Does anyone know if this is definitely a hardware issue? Is it possible that it's a bug in Google Maps that's causing the problem with ICS?
It doesn't have to be Google Maps it self. I have it in other apps as well which use the GPS.
Might be hardware, might not.
One of the main reasons I upgraded from the Galaxy S (fassy) was that it's GPS chip went from working not very well to not working at all. If I'm paying for a smart phone, I would like a to have GPS and maps.
So far I have not been disappointed with the GNex's GPS at all. Maybe I lucked out. Try downloading GPSfix from the market and see if that helps.
I have the exact same problem here in Sweden, went for a run and it would not lock on to any satellites at all during half an hour. Really disappointing, thinking of returning it due to this...
Has anybody found a solution to the problem maybe???
was having same problem
Hello fellow GNex users having the GPS issue.
I was having a GPS problem as well where when using Google Maps or Navigation, the GPS status would say 'searching for GPS' forever.. maybe after 10 minutes it would get a lock and operate normally after that.
I downloaded an app from the android market called GPS Test to try to get some better idea of what could be going on.
When I ran the app, I noticed my phone would pick up a few satellites (satellites in view) usually 4 or 5 satellites, but it would never use them, they would just appear as in view without being used for a location, and the GPS test app was never able to report my location. From within the GPS app settings I was able to clear aGPS and update aGPS, but the same behavior would reoccur where the satellites would be in view but would not be used for location.
I tried toggling Wi-Fi, clearing out other location methods, and even going into airplane mode to use GPS only, but same behavior.
What I finally did was clear aGPS once more and then immediately power off the phone, pull the battery, wait a couple minutes and then replace battery and power back on.
Upon going back into GPS test, I did an update aGPS, and then I started to immediately pick up satellites and use them for location. Toggling all the same data connectivity settings (Wi-Fi, location using towers, airplane mode etc) I was continuing to get the same positive response.
I have tried to use google maps and google navigation again and am getting near immediate GPS locks. Comparing this to my Nexus One, the lock is much faster and with about the same accuracy.
This seemed to solve my problem for now, I hope it might help anyone else.
Phone information:
Verizon Galaxy Nexus
Stock Android ICS 4.0.2 Build ICL53F
subsonicbug got it right...
I had the same problem of never syncing GPS, I follow the suggested method and voilà 2 secs GPS sync...
You save my day
Thank you
My gnex was having similar issues, after reboot it would lock quickly, but after a while it would take forever and never lock
Been using this to reset / download agps and it helps a ton!
https://market.android.com/details?id=com.eclipsim.gpsstatus2
subsonicbug's method was the only thing that got my GPS back to usability after several very frustrating days during which my GNex could barely see two or three satellites (and not get a fix on any of them) even under an open cloudless sky.
He or she is clearly on to something...now let's hope that we (and by "we" I mean people way more knowledgeable than me) can figure out why a significant number of Galaxy Nexus devices get so far out of whack that only a soft GPS state reset followed by a battery pull can get GPS working again.
there's actually an easier way that doesn't involve a battery pull. download the app "gps status & toolbox", press menu, tools, "manage a-gps state", reset, after a soft reboot go back into the app, follow the same process but instead of pressing "reset" press "download" after the download you should be good to go. hope this helps!
FasterFix works for me, make sure you have busybox installed.
The unit I'm currently using says location unavailable after resets, pulls, wipes. Hardware problem? I do get intermittent flashes of use.
Here is a fix that may work. I had the same problem and this worked for me, got a gps lock with gmaps in less than a minute. I have the VZW GNex, rooted bootloader unlocked, works with any rom.
Conditions needed:
1. Phone needs to be rooted, I believe, if you have success with out root please share.
2.file explorer, I use root explorer
Now follow these steps:
1. Open root explorer, or any other file explorer
2. Navigate to /etc
3. Ensure the system is mounted r/w, if using root explorer press mount r/w
4. Open gps.conf with text editor
5. The first line will say NTP_SERVER=north-america.pool.ntp.org. Where it says north-america it could list a different continent depending on your location.
6. Edit this line by removing the north-america
7. It should now read NTP_SERVER=pool.ntp.org
8. Save the file and exit
Now open open any app requiring GPS and you should get an instant lock, or pretty close to instant.
hmm my issues seems sorta wiered too -.-

tracks seem always loosing lock and so does navigation and other tools

GPS Location

Ever since the latest updates, our GPS Location service has no longer been functioning. Unlike before where the GPS + Data updated me of my location in real time, now the GPS shows "No Service" or "No GPS" (Waze), Ive tried numerous GPS Apps like GPS test, GPS Location fix, and so on to no avail of a fix, it also shows No Fix on GPS Test (Meaning that it doesn't detect any GPS Satellites) unlike before. When I was on the very first stock rom firmware, my GPS locked immediately at the same time updated me in real time of my location, whereas now, without GPS my location skips from one place to another as it base's my location through Data connection.
This isn't only for me, I have three other friends as well who own ZE550ML's (As we bought all at the same time), and this is our biggest concern right now as we travel with a car.
Any manual fix or latest update for this will/ shall be greatly appreciated.
P.S.
• I have tried flashing the latest firmware as well and still my GPS wasn't working. We all tried.
• I've also tried asking via ZenTalk to no avail...

GPS not getting a fix (HTC One M9) but seeing satellites, GPS.conf file

Hi – I've recently started using a HTC One M9 (himaulatt, developer version). I've realised it won't connect to any satellites and so navigation doesn't work (not accurate enough just using mobile data to track my route). It was originally on MM but I went through all the OTA updates to bring it to N (7.0), version 4.30.617.12. I then unlocked and rooted, installed lineage 14.1 and all seemed well until I spotted the navigation issue. I tried the latest Venom ROM that offers some GPS initialisation. I've now returned the phone to stock 4.30.617.12, again with no improvement.
I've followed all the steps for resolving I've been able to find, including at https://www.technobezz.com/fix-android-gps-issues/ - and I've been using the GPS Status & Toolbox app as well as GPS Testing Tools. I've repeatedly cleared AGPS data and downloaded it again using GPS Status. I've removed other apps that access GPS and cleared cache on those remaining (Google Maps, and the two mentioned above).
The apps report very occasional single satellite fixes being made, not sufficient to help with positioning. The phone detects that there's as many as 25 satellites in view, once AGPS is loaded, but doesn't use them. On GPS Status, some are reported in blue (“only rough orbital data (almanach) is available”), and sometimes some in yellow (“all orbital data is available, but the satellite is not used” - THIS IS VERY PUZZLING). Another phone that works well with GPS reports the same / similar satellites above, with compass giving a 10deg different result even after several rounds of calibrating..
I'm now looking at the GPS.conf file, have tried several available online for UK, and have edited it myself in response to online advice. Any tips? The one given via stock has the following last few lines, does it look OK? )...
SUPL_VER=0x20000
PHONE_TYPE=UMTS
CAPABILITIES=0x33
Advice very welcome and appreciated – otherwise I'll have to sell it on with the fault declared, probably at a quite low price.
Many thanks, Geoff
Flash back to stock and start over. Its a bug. The other symptom is false location reports.

GPS problems

Anyone having gps problems? When Google maps does eventually lock on a position is seems to be miles away from where I am, it takes Google maps a good 5 minutes to actually figure out a route.
Currently on China rom 10.4.11
Works fine here. Did you give all permissions in app settings. Settings>Apps>permissions >accept all
I'm also having the same problem at the moment. But in my case gmaps doesn't even detect my position at all. Also on china rom 10.4.11.
I've enabled all permissions, change gmaps to no restrictions on battery setting, still doesn't work.
Funny thing is, waze detect my location just fine.
Any suggestions to fix this issue?
What do GPS Status apps show that you can download from Play Store (you only need free, ad-less apps). You could compare the GPS signal of this phone to other phones you have around.
I´m using a REDMI NOTE 8 PRO for 4 weeks. I´m having trouble navigation with the GPS. I tested it with Gmaps and Waze. In both, there are changes in the route without any change in the route traveled. I´ve already checked all the settings (Battery saver, precision location on Gmaps...) without sucess. Aparently the accuracy is low.
What worked for me was uninstalling maps updates, clearing maps cache. Than install gps status from Google play and from the drop down menu select manage agps and reset it . Hope it helps.
