GPS Lock, anyone with issues?

Has anyone managed to get their GPS Locking in Google Maps?
I've used QuickGPS to download the database and set Google Maps to use GPS but it never gets a fix.
When in TomTom it knows theres satalites about but doesn't connect to any.
Wondering if I have a duff.... anyone else?
How fast do you connect to satalites?

Have you been out of the house? Some houses really interferre with the connection.
Also, maybe there are some settings in the application you have to change? It should get a fix pretty quick. (first time from 10 sec tot 60, after that, below 10 sec).
So you have updated the quick GPS? Did you (after running tomtom and getting the update for the first time) do a soft reset?

Yeah, did a soft reset after I turned A-GPS on in Advanced Config program. Have tried it in work which usually gets a fix, but will try outdoors, just thought I'd ask the question first

why did you do it on in advanced config? maybe that's where it went wrong. Can't remember me having to put A-GPS on in advanced Config program.

I had the issue in google maps where I could not get a lock. I had to manually configure connectivity to com port 4 in settings.
After that it has worked perfectly. I cannot say if TomTom works or not as I am waiting for my ne SD card to be delivered.
I have however noticed that everytime I sync with active sync QuickGPS always moans it is out of date even thoguh I might have updated it about 1/2 an hour ago.
Its not a major issue as its connected to my PC and just downloads the data again. i'm just ignoring it.

Do not use A-gps.
I have my TP2 fixing with no problem without it: first fix in 55", then always under 10".
Try and use for first fix Quickgps.

Brilliant, turned off A-GPS and loaded TomTom 7.915/Google Maps, got a lock, even indoors.
Spot on, thanks for that!

Turn off A-GPS?
I keep seeing that to make the GPS work better, while also using QuickGPS, the A-GPS should be turned off?
How do I do this?
I have only had the Touch Pro2 for a few days, but have not been able to get a satellite lock in Google Maps even when standing outside away from many buildings.
If it would work better with A-GPS disabled, please tell me how to do this!
Thanks,
Dazzer

It should be turned off by default, I turned mine on using a program called Advanced Config.

Ok, thanks, just going to go try Google Maps again to see if I can get a lock. Maybe I just wasn't outside long enough, or far enough away from buildings last time.
Hopefully I can make GPS work soon

Ok, I just sat outside for about 20 minutes, in the middle of a field, away from any buildings, and was unable to get any GPS lock!
What is wrong here?
I have not touched the GPS Port settings in the control panel, but Google Maps only says Seeking Satellites (0) all the time.
If I do change Google Maps to use COM 4 Baud 4800, it gets worse and says Seeking Satellites (48037656) or some other equally stupid number! At least 0 makes sense, as there are not millions of GPS satellites, only about 20!
Please help, surely there is some way to make GPS work?
Thanks,
DW

Hi all,
AGPS is not currently supported by any UK Networks, so should be turned off if in the UK.
Cheers,
Beasty

i think i ended up setting all mine to com0 but i think it wasn't working originally coz i was sitting in the car and it badly needs a wash (yes that bad). Just stuck it up by window for around 2 mins and it had 8 satellites but i've reset it so often since i last used the gps i wouldn't have been surprised with around 5 mins ... 20 on the other hand is a bit daft

Yeah, I'm beginning to wonder if there is something wrong with settings somewhere, as in 20 minutes outside it never indicated a single satellite in Google Maps.
I have downloaded the Advanced Configuration tool, and it says that A-GPS is Disabled, which is correct for the UK, so there is nothing to change here.
I have tried changing the Port settings, but I don't know what I should change it too. The Hardware GPS port is blank!
Getting close to giving up for the day, but I really want to get GPS working soon!

Ok, I had the same problems, have you updated Quick GPS? Are you using Google Maps?
If you go into settings and go to External GPS my GPS Program Port os COM4 next page GPS Hardware Port is none and Baud Rate is 4800.
Make sure settings are same and restart phone.
Have you installed anything since getting phone? Might be worth doing hard reset and trying is "out of the box" so to speak.

I could confirm the GPS is working and flawlessly! Much quicker than my old HTC P3600i and the locking is done in the CBD area!
I used the QuickGPS (download the latest update) and then using my GPS software called TechrificWay for Australian (it's a rebrand of NavNGo iGo MyWay 8)
Very happy ^^
(I need to set the TechrificWay application settings to find the GPS unit on COM4 though)

I actually spoke to HTC today and they think it's actually a fault with the hardware, possibly the internal antenna for the GPS is not connected properly.
Slightly annoying as I now need to send it back to get a replacement, or have it repaired, but good in that it's not a problem with me using it! There definitely is something wrong that I can't fix, I just can't wait to get one that works now!

I can get a lock, but get bad lag, and it wonders off course regularly. I wonder if it could be that the radio is not that great for GPS, as many other HTCs have suffered with GPS performance that has gotten better with certain flashed radios?
HTC gave me a generic response of "check these settings" (which were all as they should be in terms of com port and baud rate etc... So I think I'll have to call them if it keeps crapping out on me

(Fortunately) For me it turned out to be a genuine hardware fault causing the GPS to not work. I spoke to HTC and they believe I was the first in the UK to need to get a replacement due to a genuine hardware fault, which I guess is an honor (just a very annoying one!).
Even with the GPS not working for the week that I used it, I loved the handset, can't fault it, and can't wait until tomorrow when I should be receiving my brand new replacement, hopefully with working GPS and no faults!
Thanks for the suggestions here though, I needed to make sure it was a hardware fault before sending it back for a replacement.

I've tested three over 30km trips with Tom Tom 7 installed on the device.
Haven't lost a signal once. So it works fine here in Finland.

[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:
imgur.com/VFc3s
(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.

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 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.

AL00 GPS not working

Got the phone from Wonda in December. Have now just notice that GPS is not working. Haven't attempted to use GPS before so don't know if this is a new problem or not.
Have downloaded several GPS tools but none have helped. One tool (GPS status) does not even show any satellites.
I have previously removed some apps using adb following guides given in these blogs but have not seen any reports of similar problems. So at this stage I'm not sure if this is a hardware or software issue.
Have carefully checked all settings and can't see anything that would stop the GPS function. But, looking on the web I came across an image of the "location access" settings screen. This shows additional location mode settings which includes GPS but these options do not appear in my phone settings? So maybe that is the issue.
Have included a screen shot of my settings page and a copy of the web page image that I found.
Can someone please confirm if Location mode is or is not included in Location access.

what is your phone version number？Is it after the upgrade？

Its an EVR-AL00 and had all updates installed.
I'm not sure what/when affected the GPS. It may not have been working since I took delivery from Wonda.
Did a factory reset today and GPS is now working fine :good: and now I know that the screen shot that I took of my phone location access settings is the standard for EMUI 9 (GPS is not shown as additional location mode settings).
So it will remain a mystery but would edit the title to show it is 'solved' - if I knew how

No. Thought of that at the time. Took it out of its case but still didnt work. Not even outside the house. Only a hard reset fixed it. Now it works in the case, in rhe house, everywhere ?

How you know not work? You can't choose between gps and wifi net?

HTC M9 Nougat, NO GPS

After a whole buncha roms, I have my mystery HTC ONE M9 working, more or less with [Sprint_HTC_One_M9_4.27.651.4_RUU]
IMEI is showing up, as is LTE IMSI and CDMA IMSI, so -- I THINK -- the phone part is finally working (can't test until I wangle a replacement nano-sim
off my carrier, cheapo sim cutters are crap). However.. STILL NO GPS. When I use a simple GPS TEST app, eventually the "sky map" fills up, satellite dots eventually update and change number IN VIEW and position, but never a fix. The only way I get any location is when I turn on "Location=>High Accuracy, which just uses stored google and wifi info.
Somewhere deep in the filesystem is something that handles GPS and it is pooched and has stayed pooched since I had the brilliant idea to install Lineage OS on a Sprint CDMA/LTE phone (had no idea at the time) (It looked and ran nice.. just no IMEI or GPS).
So, I have read all various easy fixes for GPS problems with the M9 and tried all the usual, plus the ad-filled apps but this has remained DEAD even when I started fresh from an 3.41.651.41_RUU. I have wiped everything that TWRP let me wipe. I have factory rest endlessly.
Gotta get TWRP back on it, then Magisk and get rid of the evil self-register thing..thing...thing.
This was a $60 Aliexpress refurb, which means new back case (no sno/ID) and battery and I was more or less satisfied with it until I set out on search for something more than Marshmallow/ Android 6.
Anyone a GPS expert? From the forums, I see that this is a problem for a lot of folks.
Thanks and regards, /Z
