[Q] Gps losing signal after an hour of good working - Android Q&A, Help & Troubleshooting

Hello, I'm basically new to this forum, but I used it a lot for many questions that I wondered. I have a strange issue with gps on my Jiayu G3T 6589t mobile phone. I start gps navigation app, little wait, get signal, and it is working really good, but after an hour of using, gps start to loose signal every 2 minutes, and get it back repeatadly. All what helps is that I go out from navigation app, turn off gps, open aplication and start gps. Does anybody knows what may be the cause, and how to fix it. I already have epo file and full agps. I used copilot, here beta, and sygic, and always the same..

GPS Instructions w/ new Rom for TomTom and LiveSearch

Everybody has been stating that they got GPS to work, but only some left instructions. I hope this helps. Thanks to those that gave me advice on how to get this working.
Make sure unter "External GPS" that the "GPS Program port:" has "COM4" selected. Leave "Hardware" alone which is the next tab over.
Then under "Access" make sure "Manage GPS automatically" is checked
Live Search for some reason wouldnt work until I got in my car and drove away from my house. Right when I drove away, the GPS kicked in, and worked as if I had an external GPS. My settings for Live Search are "GPS COM4".
In order for TomTom to work, you first have to get your GPS location in Live Search, then launch TomTom, and then TomTom will work fine as if you had an external GPS.
My TomTom settings are "NMEA GPS receiver" then "com 4" then baud is "9600".
These are the steps i took to get GPS working with the new ROM update using the internal GPS. Havent been able to test the Rev A yet. But it seems everybody is stating that is working fine, but only some were able to get GPS working.
Hopefully this will help you all to get GPS working with the new ROM. W/o me doing these steps, I wasnt able to get GPS working. Also please note that I had to leave my house for it to work. With my Bluetooth GPS receiver I could get a location in live search or Tomtom w/o leaving the house. But for the internal GPS, i had to leave the house.
Have you tried with google maps. For some reason i can get GPS signal in my house with google, but not with live. Also, under the GPS hardware, does yours say none, and baud 9600 or 4800?
Edit:
Never mind, I got it working, live just connected in my house. I have baud set to 4800, don't think it really matters. (anyone know what baud is anyway, and what the best settings are?). I wish there was a way to do this without live though.
baud is just another word for bits per second, its the connection speed of the hardware, since its internal it probably wouldnt make much of a differnce

I have everything working but tom tom 6. It says no GPS device what gives? Do you have to have Live search running in the background for tom tom to work. I close Live Search after aquiring five satellites then launch tom tom 6 and all I get is no GPS device. hehe I know this is a beta and not a release rom. I have no Idea how people can aquire a satellite in their home. Shesh I have a huge solarium and still have to go outside.
what do u mean you get five satellites? Also to answer your question, what i do is after getting the GPS fixture in Live Search, I just click start and go to Tom Tom, without doing anything to live search. It seems to close automatically when I open Tom Tom.
Does anyone know if the GPS signal comes via the Sprint towers or is my phone communicating directly with the satellites in the sky? I ask because getting a signal inside my house seems unreal.
GPS signals come from satellites which is why the signal degrades when you move inside, eventually becoming nonexistent or unreal.
When someone says they are getting five satellites it means that is how many signals their device is receiving and using to triangulate its position. It requires at least four satellite signals to triangulate a current position and the more signals it can pick up on the more accurate the triangulation.
Ks.
when i said "unreal" i meant unbelievable i have a globalsat BT308 (which is kind of old, i bought it in 2000 or 2001) and theres no way i would ever get a signal inside.
so even if i go out of sprint reception area i can still communicate with the satellites right?
For some reason I always have to setup the GPS device in TomTom. It works but as soon as I close TomTom it looses the GPS settings. Then I have to run through the setup again...
Anyone else having the same issue?
My GPS wasn't working at all until I turned on GPS location under the phone menu. Location Settings under services.
Once I turned that on my GPS started picking up satellites with in 5 seconds sitting in my house.
Does Anybody know how to get the GPS to work with iGo 2006? I am having no luck at all getting iGo to recognize the GPS device.
TomTom appears to have a bug where it does not see the port windows gps port sharing is showing because the hardware port is set to none (I think it's actually com1 for the real hardware). As a result until something OPENS the port for tomtom, it's unable to attach to it. Until this is fixed you have to launch some other program that does work first and leave it open for tomtom to open the port.

Theoretically, you should be able to get a GPS signal anywhere in the world.

I understand that they can selectively disable regions now. (read about it in the paper when they unfogged the signals) so conceivably,we wouldn't be able to use our moguls in iraq or afganistan.

I think what they do is place devices selectively in those locations that send out false GPS signals to confuse the NAV devices. (probably from ground based stations or on moving convoys that are trying to NOT be detected)

Has anyone gotten Garmin Mobile XT to work with the internal GPS?
I am going to hold off on Flashing and give DCD some time to mature the release since I already have a G10 bluetooth reciever and have no issues but it would be nice to be able to leave that in my car and use internal when I'm not in my own car.
As far as i know...these are govt sats that are "open to the publuc." In a state of emergency or other situation, they can be blocked or certain areas can be blocked so only, say, certain govts/military could use them. This was the only way the us govt was willing and able to let the gen pop use the sats.

GPS Problem

Hi
Seem to be havin a great deal of problems getting the GPS to start in programs, like TOMTOM and google maps. I have installed and tried gpsplex and gps gate. and have had some connection success then nothing.
What are the best settings to have the com port on or none or gpd etc.
When updating gps position it will do sometimes then it says failed to save then it does sometimes.
Getting tired of this phone and weakening for the nexus one or back to apple.
search the forum you will find it.

Set com port 4 in External gps,then set gpsgate. Enter Intenal gps and download(check your internet connection if on , if not, try once again,if still no positive result , soft-reset,try again.) After getting gps-data, power on gpsgate, check for incoming data(OK),power on tomtom, get in open air until you got a gps-fix(depending on certain factors it can take a while 2-3 minutes), everything should be fine.
Let me know your progress(or not).
Hi
Thanks for the reply, ended up doing a fresh install of everything and after boot gps worked first time with google maps with gps on default setting of GPD9 in external gps setting, did the internal gps update over wireless lan as it seemed to work better than cell connection.
Installed GPSMod driver and bingo tomtom found it and everything ok.
But later after a few active sync sessions i went outside and again nothing off both google and tomtom, no sats found. Did a power down and again everything seemed to work, strange !!!. So that where im at, a not to reliable gps connection.

I was really frustrated with gps disconnections at first, was the only thing that bothered me in this phone, other than that i loved it. The problem is clearly a matter of rom's radio. When i had a rom with radio version 5005.1600.05 i had disconnection in GSM phone mode but steady signal and no disconnections in HSDPA mode. Problem fixed in 3G/HSDPA mode. Since i flased a rom with radio version 5005.1700.05 i had never gps disconnection problems in both GSM/3G mode. Problem gone!
If you have the stock rom installed, try turning the phone to 3G/HSDPA mode if it's in GSM and check again. But i advise you to install a rom with 5005.1600.05 radio version, great call sound quality and great satelite connection. I personaly found this rom Revamped Release 5 Loaded Radio 5005.1700.05 05/21/2010 best for me and will stick with it for a while.
The phone is ok, this is not a hardware issue it's clearly a matter of radio driver. Don't quit on this phone yet, it's a great device if you can cope with charging every day . But this is the case more or less with big screen-1ghz-small capacity battery phones, except if they have led screen

GPS In Optimus One

guys, i can't let the gps using satellite in my optimus one to work...
always says "Waiting for location" .... like using the carhome or the navigation bundled applications pre-installed...
any fix please?
You have to wait for a lock. That's normal.
Also, Try waiting for a lock outdoors. GPS signals aren't as strong as the ones used in SMS and stuff.
@ kp
ive tried waiting for quite a long time but nothing happened...tried also outdoor but the same...
ive tried using GPS Test application to located GPS Satellites, and indeed it can locate some with low to average signals...but when i am going to use the pre-installed applications for tracking my location, it still can't.
ive searched the net and someone also is having the same problem using LG Optimus One as well.... >.<
Depending on your firmware this might be a bug. There were GPS problemes reported with certain firmwares. But you have to be patient too, because sometimes it takes a while until 2 or more satellites are found and locked.
You can try using free app like "Ulysse Gizmos" on monitoring gps, especially on lockon status.
& also try this tips to access the internal gps test menu @ link: goo.gl/ZFs6D
Our LG Optimus One P500 code is 3845#*500#
Do let us know how it goes.
Good luck!
I use the P500 whitout a data connection. So does have a sense set the gps in A-GPS or if i have the data not active i have to set it in a GPS Standalone?
restart phone and try again
are u using da stock rom?
@Hesediel
If you don't have data conection you cann't receive any maps, but it's no problem to use a-GPS. But without data you will simply have the geo-data, no maps. So that seems to make no sense.

Yes but i would like to buy an offline navigator like sygic, copilot, ndrive, something like that not the google maps/navigatopr for now, so it's better i use gps as standalone or is the same setting it as a-gps ms based?
it's a known problem.
I've got a p500 without data connection (I'm using wi-fi only).
The first week after flashing my phone the gps works fine.
Then afer a week the gps fix begins to be sloooow.
After a month it is very slow.
So I have to do an hard reset to turn the gps works well again.
Any utility (like gps status) that try to reset the gsp... fail.
The only known solution... is a ... sadly... hard reset.
I hope the someone will be able to write an application to do the same thing like the gps hard reset.
Use fasterfix, you can find this in android market.just search for "fasterfix"
Requires root, busybox and data connection during the initial GPS lock time.
Your gps will get a fix within seconds.
Sent from my LG-P500 using XDA App
I have a problem with custom rom ( openoptimus) and gps.It takes to much time to lock to gps and sometimes i have to reset the phone in order to work...I have download the faster fix but it hasnet work

Well, i have the same problem and used the same solution. But now I just wait. Sometimes I "cold start" gps with GPS Status or even the "hidden" gps test menu and after waiting a little or a lot (30s or 10min) I get GPS fix. Anyway, restarting the phone seems to work well too.

GPS Problem

I have a GPS problem / question. I'm on Galaxy Note fre3 Hybrid De[Odex] v2.11 but I don't believe this is a ROM issue. I have certain apps that require location services and GPS to be on, example would be the WWE app or even our SBarometer app. If I turn GPS on and enable location services, the apps do not detect that GPS is on and I have no GPS icon in my status bar. If I use GPS Status it's fine. Any ideas? It's not app settings because on my Mega when I open the same apps the GPS icon comes on immediately and the app works properly.
Have you found a fix for this? I am on stock 4.4.2 with root, and I have been having the same GPS issue for several months now. Whenever I use Waze, it's constantly looking for a GPS signal, and MapMyRun will find it and drop it several times while I run making it impossible to track my runs. One other thing I did notice, is when I'm using Waze, if I turn the screen off, it locks on to the GPS. I can tell it's locked on because the voice commands start giving me directions, but when I turn the screen back on, it looses the GPS signal again. I would really like to get this issue fixed. The only other option will be to take it back to Sprint for an exchange.

I too am having a GPS problem. I'm Stock and not rooted with the most recent Sprint OTA (NK4). I've been suffering with this since NH7 came out and no ROMs, stock or otherwise have fixed my problem. Any recommendations on what I should flash? I'm considering doing an Odin Flash of NC5 just to see if that would help.
I have read through this thread, the first thing I would try is to update your PRL and profile. If GPS works on some apps and not on others I'd be willing to bet there's nothing wrong with the device or a stock rom running on it. I would try and contact customer service for the app and see if others are having the same problems with the apps., and see if there is a fix.
https://play.google.com/store/apps/details?id=com.androidlab.gpsfix I've heard people say this app has helped them with there GPS issues. Hope it helps

UMI Plus - GPS/Navigation Problems

Hello,
I get a GPS fix within 10 seconds. But with Maps, however, the signal jumps back and forth. Also, the signal does not show exactly the location, or a few meters away. These problems are probably also known to the UMI users. Somehow I have read what of MTK tools, where this problem can be fixed. Can someone post a tutorial, or link?
Thx.
Hi, looking forward to fix the same issue... Any news?

Gday mate,
I was having similar issues with my GPS jumping to the street next to me whilst driving and getting itself all turned around. The other issue I had was bluetooth would not connecting to my car, so I tried a few things on this list: http://www.theandroidsoul.com/fix-nougat-bluetooth-issues/
Specifically what seemed to fix my bluetooth AND GPS was this: (I also set the passcode on the car to '0000')
"This is a really good fix, confirmed to work by many people. To reset your Bluetooth settings, fire up the Settings app, and locate and tap on Backup & reset option. Now, touch ‘Network settings reset’, and then ‘Reset settings’. Confirm this on next screen. Note: This will reset all your settings related to WiFi, Bluetooth and mobile data. Keep that in mind. If you need WiFi urgently, then better do this later on."
The above made my GPS a bit more stable. Since then I have updated the device to the latest beta: PLUS.V3.02_20170208_c239v55_kw_u3_no-DB and GPS is working perfect now. Link from bencebacsi on UMi Forum: http://www.mediafire.com/file/hh1069alx7v8i6i/PLUS.V3.02_20170208_c239v55_kw_u3_no-DB.rar
Best of luck mate!
hello guys!I bought the Umi plus a week ago.The device is pretty cool but i have issues with the gps.I tryed fix it with some youtube videow but still nothing.Can please anyone have found a solution for this problem?

It's not usable for this problem.
I tested Faster GPS after rooted, MTK tools, Engineering Mode, and another more tools and tricks, and nothing helped me with better gps signal on my UMI plus.
In enginneering mode I deleted data from hot, cold, warm and full gps start without A-GPS started, A set position from detected position, download new satellites positions, then start A-GPS and it was same how before. GPS signal on Mediatek chipset is bad.
Sometimes I have fixed 12 satellites, another time zero satellites. Gps signal jumping from zero to good in the car, or outdoor.
