Gps not working - Android Q&A, Help & Troubleshooting

Hi All,
I just wanted to share my experience using the gps, at first without trying this, I can't successfully get a lock on gps satellite so gps is not working and can't catch my location but after doing this, it works good now. I can get a lock for almost a seconds.
SET your android device to use GPS ONLY and not HIGH ACCURACY
sometimes cell sites overrides the location throwing by gps that's why it is not accurate!
Voila!

[Q] Another GPS question...

Hey guys,
Here's a quick rundown of my situation: I've had my GPS connector replaced per the instructions in the "Correct Hardware Fix" thread. I've been running tests using both the integrated gps test menu and the Chartcross gps test app.
For starters, I've found something quite curious about the Chartcross app. Despite the fact that I have "Use Wireless Networks" disabled in location & security settings, the Chartcross app does appear to use network assisted gps.
Chartcross Tests
Test 1: Place phone in airplane mode, restart, run test. Finds 3-5 sats, maybe connects, takes forever nevertheless. In other words, sucks.
Test 2: Re-enable wireless data. Restart. Run test again. Immediately sees 13 sats, connects to 7 fairly quickly (inside even). Again, this is despite having "Use wireless" unchecked.
My GPS is obviously working (and working well), so why the hell will it not connect while data is off? I'm totally stumped...any advice would be much appreciated.
P.S. I've tried Nero v5 (awesome, by the way) and stock 2.2. Pretty sure my phone is a July 2010 model, if that helps.
I had some slow connect issues with Nero v5 as well. I got mine resolved by flashing a newer (KA7) modem.

I'm getting awful gps with the ka7 modem. How was your gps before hardware fix?
Get a clue people, read the Vibrant advertisement. The Vibrant has GPS assist NOT GPS. That means without the Cellular connection just relying on the Sats for the connection, the GPS will be sucky and slow, but it will work without the Cell/wireless signal.
i am using KA7 and i am getting 11-14 in view and 5-7 lock, fast locate.
Without Cell signal i get 5-8 view and 3-5 lock takes 45sec-1min
But this could because of where i am and most likely why people have different performance of the GPS

Sorry man, I didn't realize the distinction.
So let me get this straight:
An assisted GPS uses some sort of wireless data regardless of whether or not the "Use Wireless Networks" box is checked in Android settings?
GET A CLUE PEOPLE! lol

Is there a GPS fix for SGS II

Hi all! Is anyone having problem with the GPS? Mine is taking ages (if at all) to lock in on my location. Only Google Maps was able to lock in on my location within a few seconds, but other apps are taking forever to find my GPS location. I tried GPS Status and the waiting circle keeps on circling forever! Is there a fix for this?
Only GPS fix for SGS2 i am aware of is fasterfix and that only changes the NTP time server to a more local one .
jje
Thanks, JJ, you're a great help on this board I figured that it was my firewall which was restricting network access of the apps so they were not able to find out my location. The apps use a combination of GPS & cell/wifi network to lock the location, so I just gave them access and they started working.
Installed Fasterfix too, it's a useful tool.
Cheers!

EDIT: the only real GPS dead zones are underground and on a very rare occurence when your time and date aren't synchronized with that of the GPS sattelite. Other then that, have you tried to enable GPS in settings (would be weird if it was disabled by default). It also matters if you have a data connection when using some apps (I have never gotten google maps to show me where I am when I have no data).
Hope some of this is useful to you

By data connection he means a wifi connection.
GPS uses data always. So it needs a data stream to get and use location services and maps.
On a phone it uses cellular or wifi but on an ipod style device or the galaxy player it needs wifi.
Without wifi it will never work unless your gps config files are modified; which is something i learned when trying to get the Acer Iconia GPS to work. And even then its probably not going to work.
Turn on wifi. I bet it works.
You now may be thinking "then what good is gps when i do not have a data connection!!?" - and my answer is exactly!!!
Gps on these devices is a gimmick and really only works when wifi is available.
True gps like a tom tom device doesnt need a wifi connection because it uses the gps link iyself for the limited data it needs plus the maps are built in.
On the galaxy player and phones the maps are downloaded at needed because they are hundreds of megs .

The Galaxy Player works fine as a standalone GPS without need of a wifi connection if you have the right kind of app. I use Sygic but there are several others. You download maps from Sygic to your player so they are available on your device. Works fine on my 5" Galaxy Player. Also there are apps like speedometers which use the GPS and work fine without a wifi connection.
I use Sygic. And also use pre recorded areas in Google Maps when I need it. No need to WI-FI, etc..
It is a good GPS 5 ".
In fact, very good.
Until now no problems experienced with GPS. If you do not connect may be related to your area.

The GPS technology works perfectly fine without data connection. To speed up the first fix, aGPS was developped and uses a data connection when available, but data connection is not mandatory. It's what is used in most if not all smartphones (search for "assisted gps" in wikipedia).
Data connection are required by some navigation software because they need to download the maps or for some obscure reasons. It's the case with google navigation for example.
But you can use a software that doesn't require data connection and store all its map on the device and only uses the GPS signal to do the fix, as gotok pointed out correctly. An android device with a good navigation software is no different than what you call a "true gps like tomtom".
I think you just don't make the difference between GPS (the technology) and navigation software.
I agree that the samsung S wifi's GPS capabilities are not very useful "out of the box" with the limitations of google navigation, but it can work perfectly fine with a good software. Don't blame this device (or any other one) for the shortcomings of google navigation and some other software.

The software is definitely an issue. The SGP i got for christmas couldn't utilize its GPS at all. Regardless of what app tried to use GPS location services, i always got a location error (E.G. Location unavailable at this time.) After doing a little searching, i found that someone had an app that fixed a similar problem. I downloaded "GPS Status & Toolbox" and let it run. Its primary use is a compass and getting information about location, but after i opened it and let it download GPS configuration information, everything worked perfectly. Maps showed where i was, Facebook gave me nearby locations and so on.
Dont know if everyone figured this out already or not, but after reading over most of the thread, i didn't see a definitive solution. Just thought I'd share what i had found.

Data connection is never "mandatory" but with some GPS chipsets, it effectively is.
Some chipsets are so crippled they are almost never able to get a lock without assistance.
See the original GalaxyS phones as one example.
The Infuse is improved but not much better.
The Galaxy S II is VERY good at standalone operation.
Galaxy Players - ???, no clue
The GPS works fine, without wifi, on the Galaxy Player 5.0. To test it, get GPS Test (free). Of all the devices I have ever had with GPS (including Nokia phones, LG Android and HTC phones, Garmin) the GPS is the fastest I have experienced. Locks indoors and on moving trains very fast.
I use CoPilot mapping and navigation program and it works great.
I use "Mapdroid" (Free) and "Navdroid" (purchased) and both work great as stand-alone apps. The maps are open source maps and can be had for pretty much anywhere in the world.
Just like a real stand-alone GPSr the accuracy and speed of start up depends on a clear view of the sky, enough time to builds it's almanac of Sats and how far you are from the location you last accessed the app ( moving great distances between uses is almost the same as being turned on for the first time). The same can be said if too much time has gone by between use (such as months).
The Sat almanac gets built when your gpsr is turned on for the first time and is used as a predictive way identifying which Sats should be overhead at the current time you turn your GPSr on. Four or more Sataltites locked in gives you a higher degree of accuracy.

[Q] is there a way to improve gps without wifi?

Title says it all.
Thank you for all the inputs.

There are some things you can do to edit your gps.conf file to improve GPS lock times. If you search the forum or on Google, you should find the answers.
Still, I have found that GPS on tablets and phones pretty much requires an internet connection to obtain a quick lock if its the first time using GPS since the device was restarted. On subsequent attempts, it usually locks pretty quickly with or without any internet connection. I think this is because it uses the internet connection to synchronize your phone's clock with an internet NTP server, to ensure the best possible synchronization with GPS satellites which work entirely off time signals.

GPS problem with IMAN Victor

Hello,
Can someone please help me on how resolve a problem with my gps on my IMAN victor smartphone.
When I bought the phone, there was no problems with the gps, it worked perfectly fine.
I am not sure what happened but when I go to use google maps or waze it locates the gps satellites then it loses signal and then it keeps looking for gps signal, locates it and than drops signal.
I downloaded gps status and run the features in this app, but no change in either of the apps.
I did a factory install but still no change.
Can someone help any advise would be very much appreciated.
It is running android 6.0 . The device is not rooted.
