Edited 30/1/2012: My GPS 100% fixed (21/4/11 PICS ADDED)

EDIT: 30/1/2012.
Just a follow up on this fix. Well, got sick of constantly having to replace the tape under the battery cover. Over time it flattens, so since I now use the S2 as my daily phone I decided to open it up.
First I found the GPS connection on the motherboard. It connects to / touches a small metal piece on the inside of the rear housing. It's like a U shaped connector so I decided to lift it up with my fingernail.
For a little while it worked great but the problem returned. So I decided to open it up again and lift the connector even higher. Unfortunately I broke it leaving only a flat bottom metal piece on the motherboard side. There was now no way for the 2 pieces to touch so I screwed it completely.
So I then decided to solder a small bit on the rear housing side. I did that and put it back together. Ever since then the GPS has truely been 100% fixed. It hasn't missed a beat over the last 3 or so months of trying.
END EDIT.
NOTE: This is a hardware fix for those whose GPS is completely busted (NO sat views & lock). It is NOT a fix to improve tracking or lock or make an already working GPS better.
After flashing every modem, fw and kernal version I had completely given up on my galaxy s GPS. It had to be a hardware fault.
Back when I first got it, it was OK but a few months later became useless. This fix is hardware related and takes only minutes to diagnose and fix.
It's also probably more useful for pre-October models (i9000 international) which had this fault.
I do not take credit for finding out the fix. Credit for that goes to member 'allottios' (who heard about it from 'cbdrift') for bringing it to my attention on another forum topic.
The fix is simple. Remove the back cover and to the right of the speaker is the GPS antenna. It is covered by what looks like some sort of soft plastic tape.
Now open a GPS test app and then apply light pressure to the very top of the antenna with your finger. NOT the middle or bottom - that makes it worse.
If, like me your GPS shows instant improvement then you have just worked out your problem.
Simply attach a small piece of double sided tape or similar to the top of the antenna so that when you put the back cover on again their is pressure on that spot.
Hope you get the same results I did.
Edit: PICS ADDED: 1ST PIC - AT THE TOP RIGHT CORNER, YOU CAN SEE A WHITE STRIP WHICH IS THE DOUBLE-SIDED TAPE I ATTACHED TO THE TOP OF THE GPS ANTENNA. I DID NOT PEEL THE TOP LAYER FROM THE TAPE SO IT WOULDN'T STICK TO THE BACK COVER.

Edit (03/05) - If this fix doesn't help, you may also want to try out another fix posted by 'stockie78' (post 209).
There is also a link below for more detail, including pics for this fix.
It is not as simple as the above fix and it involves removing the housing. I have not tried / tested this myself and am not responsible if you break your phone.
"stockie78
Unfortunately the g-spot trick did not work for me, so I decided to look a little closer and removed the plastic housing.
Another guy installed on the metal thingys there a cable and I did some test, too. Again no improvement with different cables and lengths.
But while fiddling around with the metal connector I thought maybe lifting it could help and indeed this was the trick for me. Improved my gps dramatically!
So instead of something pushing the antenna tighter, the metal connector now pushes harder and improves the signal quality.
Maybe a solution for some of you too..."

I can confirm that this works for me! Got a lock in two seconds and the arrow followed my path perfectly while I was on the bus, a feat that seemed impossible before! Thanks a million!
If I let go of the antenna the gps loses it signal straight away..

Seriously this deserves a bump! Got a lock on 12 Satellites(!) when putting pressure on the top of the antenna and lost it as soon as I let go.

I`m seriously impressed. Tested on Sygic Aura, iGo and CoPilot and they localyze me immediatly !!!! THANKS A LOT !!!!!

Tried on my SGS and can't honestly see and difference

I did something similar a while back by taking the phone appart to access the interior parts of the phone. I then bent the connector for the GPS up so that more pressure would be applied. It worked great at first then started to get worse after some time. I'm guessing this is because the connector reverted back to its original position (kind of like an elastic).
I suppose this is a similar trick, but instead of applying more pressure from the connector, it does it from the cover. I'll try to get hold of some tape to try this.
By the way I have a Galaxy S from July, and GPS sucks badly on mine.

Need detailed pictures!
Hope it works!!

THANK YOU VERY MUCH!!!!
My jam just dropped. I just got gps lock within seconds... in my living room, where I had occasionally one sat in sight.
Just applied a small piece of that blue sticky stuff on the very top of the gps antenna and voilà. Cover on and lock is a go go.
Thanks for sharing this

nice one! locked 12 sats after 5 secs!
so a small tape should do the trick eh?

Getting a lock as soon as I start GPS Test! No more jumping around in Google Maps either! This is THE best fix for the SGS yet! Finally I'll be able to use my phone as my primary GPS navigator!

Is it possible for someone to post picture of area that needs to be pushed! Thanks!!!

same here too, wtf if i knew that before ... i would not have so many gray hairs
thanks for sharing
p.s.: connection stays good without any further pressure here, put the cover on again, gps still great

I can't believe this all these months, kernels modem and all kind of fixes and the solution is a duct tape, wow!
Thanks works for me!

You should see an elongated rectangle shape on the rightmost part of your phone after removing the back cover(just to the right of your speaker and sim card) - just apply some pressure on the top part(for me it takes a fair bit for it to work) and voila you're done. I'll try to post pics soon!

That would be most appriciated. I'am visual person!

This actually works!!! I bought the galaxy s back in july and the last few months I have been unable to get a gps fix no matter what I tried! After reading this thread I went outside and pushed the top of the antenna. In a few seconds i got 5 meter accuracy and 8 satellites in use! Now I have to find a way to keep the antenna pressed! Thanks a million for the tip!

Samsung should buy you more than one beer!
How much money did they spent to fix that issue?
Thanks man!

This must be the sweet spot?
Edit: ops, to late ; )
/qsec

Well guys, I would like to try it, but my display seems to stop working as I remove the back cover?! Anyone has same issue? What could be wrong?
With backplate cover on, everything works just fine, but without....black screen. Although that phone seems to be responding

GPS Antenna Hardware Hack only 2 seconds to fix GPS status ;)

This thread is only interesting for technical gifted people, because you can brick your device !!!
I would like to share a GPS Antenna Hardware Hack i found here "http://www.androidpit.de/de/android/forum/thread/435065/HTC-Desire-HD-Hast-du-GPS-Probleme-mit-deinem-DHD"into the internet some time ago.
I tryed allot of fixing apps and software modifications but nothing works realy good for daily work with gps so i started to soldering a cable (0,8mm) to the GPS Antenna contacts (have a look to the picture)
after the assembly and a new start I had after 10sec sat-fix from 5-6 satellites in the room!!!
Outside I have sat-fix within 2 sec
Here some steps how to do, but be carefull you will lose the warranty of your device
1. open the device like in the youtube video described (http://www.youtube.com/watch?v=7qm_z65LA8k)
2. solder a cable to the antenna contacts like the picture shows

of cause it had a antenna, but the oryginal antenna doesnt works realy good
i had no gps fix without my cable here and after soldering the cable i had a satfix within 2 seconds outside

Great mod!
Yep, GPS is probably the biggest problem in the DHD.
In my case, I usually get fast fixes in GPS Status, but then CoPilot or Sygic take forever to pick up the signal
The solution seems to leave GPS Status opened in the background and then opening the gps program.
Other times, rarely though, not even GPS Status can get sat fixes.
I'll be trying other radio versions. But it's annoying stuff.
Sadly, I'm not very good with soldering.

with my hardwarehack u can delete faster fix and every other gps fix apps, i tested something around 10 fix aps and mods but nothing works realy good for me.
after soldering the cable to the device it works like my garmin gps system
and hey u dont need to be a soldering good, have a look to the contacts and think about it

If I could find a way of isolating only the pins while soldering, that would protect the motherboard from any mistake I make. Like a piece of aluminum foil with two little holes in it or something.
Hmmmm... Might try that.
Thanks!
By the way, what kind of cable did you use? Anything special?

Hi, I had the idea of this set several months ago. It works fine but the signal quality is not as good as an original antenna that works well.
After 2 months of use, I bought a new GPS antenna DHD and I withdrew my cord.
The signal with the original HTC antenna is better (available on Ebay).
My Fr Tutorial (april 2011)

thats a nice mod, but really dangerous for non technichal used people.
but really interessting!!

Ok, tried this yesterday.
No soldering though, as I was scared to ruin the phone.
Grabbed a 3 cm cable from a 12v car leds and just hooked them up to the 2 pins, just twisting a little so they don't come off.
At first the results where not much different. Opened it again, rewired them and voilá.
It's like magic. Just got close to my window and bang!, less then 5 seconds.
I even wiped the phone and installed the rom again and still works!
By the way, I looked at the contacts of the cover itself and tried to rub a little bit with a screwdriver to remove possible rust. Bad news.
Most certainly, the gps problem lies with these contacts. They are too thin!
When I tried to rub a little, I started to see the plastic underneath!!!
So, maybe, the little dark dots we see in them are just the plastic showing up due to use. That's why gps doesn't work as it should.

The GPS chip will store satellite location data (in itself) even through a ROM wipe, afaik. So once you get a fix once, it will usually be much faster to lock thereafter (for a day or two, in the same location). You can use GPS Status to wipe the GPS chip's data to get a true cold fixes for testing.

I don't remember if I wiped the gps data with Gps Status.
Going to try it now.
---------- Post added at 01:17 PM ---------- Previous post was at 12:38 PM ----------
Reseted the A-GPS data, didn't even dowloaded an updated one (my monthly data plan is over for this month) and I can confirm that the lock showed up in less than 10 secs, both in GPS Status and CoPilot.
I'm indoors, on the second floor, with big windows. Phone was left against the window glass.
Brilliant stuff.

Not really. Use a small customized tool, slightly bent at the tip and insert it carefully through the battery compartment, aiming at the cover. Just a little effort will do. The cover will pop up sligthly, just enough for you to put your nail in it.

Wonder how easy it would be to get 2 of the small ipex connectors and make a small cable yourself?
would be a lot safer then soldering it...

Firstly this "hack" takes longer than 2 seconds...
Secondly a large majority of GPS reception issues in DHD are related to bad contact between phone and antenna.
So check this connection before voiding your warrenty.
otherwise thanks for the info.

so i tried this, and i had to solder the contacts on the antena to have contact with wire and little doohickey thing that pops out of the motherboard, it works better but its not that big of a difference sure i get 3 more satellite locks, unless you guys are using a patch, which i don't know about, plus sometimes it takes more than 10 second to find satellite, are you guys using a patch??

Big thanks. My GPS works again and faster than ever !

This is really handy as I have bent my contacts up so much now that they have snapped through weakness, which means I get NO signal at all. I was thinking about trying to replace them with small springs or something a bit clever like that, but this idea is even better!
Thanks for the idea

[FIX] i9000 i9001 gps final fix

Before to procede, remember all electrial component can have fault so exist warranty. If you want, procede at your own risk loosing warranty
For this tutorial is raccomanded professional leadfree soldering iron
i solved my gps problem, it is hardware problem, so no settings, gpsaids and no other solution helped me.
Problem is caused by bad gnd conductivity between mainboard and antenna. It is conduced by:
1) CONDUCTIVE GUMMY (suggest me better name if you have ) This kind of rubber was used for old nokia 8210 for connect display to mainboard. It was the mayor fault for nokia 8210.
2) back cover gps antenna: When phone become hot, antenna go back and not good touch with motherboard. Then, when phone isn't hot, gps antenna remains with a kind of "hole"
First try software fix (it not helped me) then try my solution
Solution:
Attention: it will avoid warranty, do it at your own risk, i'm not responsable for any fault.
SOLUTION: ​

here is antenna contact not used for my european i9000
Please check by yourself if it touch with your variant antenna,
if it is not used, you can remove and solder where was rubber
Now gps signal is immediate for me
Best regards
Leeno

The first picture is before and the second afterwards?

i moved in this third post the other solution,
it is easyer then solution in first post but i not like it because is not clean
Attention: it will avoid warranty, do it at your own risk, i'm not responsable for any fault.
For solve it i just removed rubber and soldered antenna to gps gnd mainboard like the picture.
Attention: if you use unprotected wire like picture, make sure it touch only gnd, not other components or you can damage phone.
Gnd require hard conductivity so
DO NOT USE VERY THIN WIRE

Where do you find the "third antenna contact"? I guess there are three and I do not want to take the second ...

here is antenna contact not used for my european i9000
Please check by yourself if it touch with your variant antenna

I thought that the other connection was for GPS

What is the reason of this post? This fix is well known. A search might be helpful from time to time. The only useful info in this thread is the fact that you figured out that the other antenna is not used.

No, sorry, you're wrong.
THIS fix were not known at all! The thread you linked just refer to pull up the OTHER contact of the gps antenna, not the RUBBER ONE, which actually is the source of the problem.
So the next time please read carefully before suggesting someone a search.
This thread is VERY USEFUL! This man deserves all the praise and should be acknowledged of the REAL FINAL GPS FIX which turned my phone into what should have been since the first day!

I was skeptical to say the least.
but this time, I have to admit: this solution works INSANELY WELL.
I made my own modded version, though. I removed the third unused antenna contact, and placed it over the conductive rubbed. no soldering involved. pressure keeps the contact in position and enhances the connection between antenna and mobo, similar but more effective than the other older solutions.
btw, I also changed server from europe.ntp.org to xtra1.gpsonextra.net, just like in my old acer liquid which locks really instactly.
connecting now in seconds in my living room (!!!) with 7 to 9 satellites. awesome. never happened before.
you deserve a huge thanks.

I did it this morning. I removed the rubber and soldered a wire between the contacts. I never had such a signal on my i9000, the gps works perfectly.
Huge thanks from here too.

anyone can post a picture of the contacts to connect on european i9000 ?
any screenshot of gps test ?
thx a lot to everyone

pictures in first post are self explaining.
I did not bother soldering anything. Just removed the unused antenna with some tweezers and placed it on top of the existing conductive rubber (but reversed upside down, though, to keep it level), I used a tiny bit of duct tape to hold it in place and to be sure it does not touch any other contact on the mobo.
I cannot exclude to solder it or use some conductive glue in the future, anyway, it sounds safer.
I can confirm this is THE solution. I am really astonished.

gps.conf in /system/etc, you need a rooted phone the mod this file.
default server in sgs1 is "north-america.pool.ntp.org" which supposedly is not correct for european users. following suggestion here at xda, I changed the line to "europe.pool.ntp.org" months ago, and now after givig a look to gps.conf in the acer liquid to "xtra1.gpsonextra.net" and live happily with that.
I do not think this is the point, anyway. My old acer liquid uses "xtra1.gpsonextra.net" and locks sats in the blink of an eye, ditto for my wife's htc desire which has "pool.ntp.org". Any software related mod could be just placebo.
as far as I know (google search..), hot glue is not conductive. if so, you are not fixing anything. but I might be wrong.

I use hot glue just from side to fix connect in place and check with multimeter all good. In my gps.conf i change from "pool.ntp.org" to "europe.pool.ntp.org" voila first fix time 00:31 and also me not use any help like wifi or mobile data just clean gps. However this fix work...

Hmmm....
I will give it a try soon.

How do you know if your GPS Hardware working or not

How do you know if your GPS working or Hardware defective
I install Dr. Ketan L16 version ROM for my note 4 and did all the instruction to full wipe and install clean ROM but my GPS not working properly ( it s keep bouncing while I drive my can and never stayed in the road but when I reach my destination GPS helper sound say you arrived to your destination although the arrow for direction does not accompany me and there is no one telling trun right or turn lift even though I make sure that I did on the helper to speak while I drive) so my conclusion is it is not working as it should be I contact Dr. Ketan and he replied to me that there is no problem and no one report that tere is a GPS problem so I would like to know and want your help on how to discover if it is GPS haredware or software problem in my note 4 my device is N910f please I am really disparete to know the solution.
please help me I do not want to change Dr. Ketan ROM it is really rock if you have a similar powerful ROM tell me it's name I tryied Kuby rom also it's very good but I notice some battery drain even though I do not use my phone and no wifi and I am not using it it drop down from 100 to 90 present in one hour also I want to mention that my Battery is brand new.

I had the same problem. My GPS used to work well but someday when I needed it, I discovered it was not working anymore. I tried many different roms, many tweaks, many apps, nothing helped, my GPS was next to unusable. I finally found the strength to crack it open. The GPS connectors were not touching the back of the phone where the antenna is, no connection was made and so the GPS was not working. I raised the pins just a little and now everything is perfect. It seems to be a common problem among Note 4 users. Opening N4 is not the easiest thing in the world, but if I have made it, then many people should be able too.
First thing to do is try this app. If you cannot get a strong lock in 1 minutes max, maybe you should consider the hardware problem.

thank you man I will try but please tell me if you have a trusted apk that can tell you weather your GPS hardware is working or not. or something similar to this.

See after installation this is what I got

I do not think that there's an app to definitely tell you that your GPS hardware is faulty. The app you used gives only clues and your picture indicates that your GPS is not receiving any satellite signal. Mine used to show the same thing. The GPS pins are located on the upper right corner of the phone, as you watch the phone from the back.
This video shows how to open Note 4, it helped me a great deal.

This video shows how to open Note 4, it helped me a great deal.

Many and many and so many thanks to your help today I am going to take my phone to a work shop and I will try the app after that and post a screen shot after that
You really helped me a big deal and a big time. at least now I know what I should do. it's all thanks to you. man

You are welcome my friend. If this is actually the problem, then it's easy to fix, once the device is open. And maybe you should tell the technician to put a tiny piece of paper under the GPS pins, so they cannot loose connection again. I did not do that and now I'm just waiting for the pins to get loose again, so I can open it again and fix it once and for all.

In any case ask a moderator to move the topic to Q&A section!

please do not move it just yet today I am going to a workshop and if it's a GPS pin problem I will report with picture then you can close it and remove it... please just wait

How I fixed my bad GPS..

Hello guys,
following these steps solved my bad GPS as you can see with the screenshots.
for each GPS test i used "Gps status & toolbox" and i tested gps fix outside, on a balcony.
Starting situation: 6/24 satellites found.. no fix.. sometimes 8-10 satellites and then fix with about 80meters error

the idea is that GPS antenna lies on the detachable module and LG did a mess designing it.
basically, if you take out your module sometimes out, probably you'll result in bad gps behaviour.
here a pic of GPS antenna's contact/hook
i taped it with electric tape in order to test if effectively it was GPS antenna
and, as expected, my gps signal went worst than first.
then i prepared a little square of aluminium foil by folding it about 4 times in order to get a certain amount of thickness
i also prepared a slice of adhesive tape by making a hole on the center
and finally i attached them to GPS antenna contact
after this i tested GPS in the same place and...et voilà!
which is exactly the same performance the phone had on the first weeks!
maybe this fix is not as elegant as possible but my aim is to make gps working before getting mad.. maybe you could simply change the module but i think that responsibility is of the other side of the contact, located on the frame. it's aluminium and maybe for warm and other reasons it loses his shape by making difficult communication between antenna on the module and phone.. take my theory as it is.. and enjoy!

Awesome guide

Verification
Can anyone else verify that this is indeed a gps contact on the bottom module? I'm using the Hi-Fi module and it doesnt have a pin like the standard chin piece does.

I believe that this is unfortunately not the gps contact .
I have tried this fix now and it had no effect on me .
But let's wait on the experience of other users .
And thank you for your efforts, albenex!

to be honest i'm not sure too..
i made this fix and noted so much differences on gps quality so i had to share it with you.
maybe this could be a starting point in order to understand why (in my opinion) every G5 at first has perfect gps and then after normal use get worst G# series GPS ever... any help/add will be appreciated

I've written to ifixit to get their impression. If I look at the teardowns for this phone, there is an antenna inside the bottom module and the lead does connect to the phone's metal back. But then again, there are multiple leads on the motherboard which does the same! As others have noted in other posts, opening the phone and raising these leads has provided positive results as well, so could it be a combination of both?
Will keep everyone posted on what ifixit says.

For me the Fix didn't work at all. I still get no GPS Connection....

GPS is NOT in bottom cover cuz camplus and hifi dont even have that + you would hold antenna in your hand ( doesn't make any sense ) , there are multiple threads overhere and no one even reads them... USE YOUR BRAIN GUYS

no it doesn't hook to the metal back.. it hooks to a while flat *Something* which is electrically conducive (tested with a multimeter)
you can note a black line which i assume is scratch made by detachable module contact when it enters and exits

Let me get this straight, the bottom part does contain a antenna, it is connect by the PCB that you see sticking out within the phone, the wide one is the connection for mic, speaker and charging, whiles the thin long one has 2 copper conductor is for the radio antenna, I have opened the bottom unit, but if people who has the hifi plus or cam plus, the manual does state it contains the anttena for the radio, meanning the GPS antenna is within the phone.
Hope this clears up any misunderstanding.

i tried again isolating the mysterious hook and got not gps signal at all for all day long.
reversing back lead to immediate gps fix.
maybe it's not gps antenna but definitively is a gps-related thing!
i guess gps signal is in such way interfered with that and maybe cleaning up the connecting spot on the white-thing attached to rear case would be a good fix. just try and explore yourselves!

interesting:
i tried some aluminum foil and I got about the same amount of fixed satellites (7) and same first fix time but there were only 16 satellites available instead of 22-28.
Just maybe there are different antennas in our phone, one for gps, one for glonass (russian) and one for bds (chinese) as they all use different frequencies. That by the way would support the fact that those 3 little pins are indeed for the positioning system

yep, surely both things are mixed.. little 3pins and wide white antenna hooked with module.. if you isolate one of them you'll break gps signal

On my G5 H850, I had a few cases where GPS was having a problem getting a position.
In all of these cases I used GPS Status and Toolbox to reset the A-GPS state.
GPS Status and Toolbox, "top left hamburger menu", Manage A-GPS state, Reset.
After doing this GPS Status was able to get a fix quickly.
Following this, the Google maps and navigation worked normally.
The H850 comes with the gps.conf file set up to use NTP_SERVER=europe.pool.ntp.org
If you are rooted you can change the gps config file to use NTP_SERVER to be something in your region. They are just commented out.
This obviously won't help if you have a hardware problem, but some might just have A-GPS issues.

thanks for reply.. but g5 suffers from hardware problems.. further tests showed me that even cleaning the hook point between module and white antenna, helped a lot.. a g5 of a friend went from +-80m error to +-4m !
besides this i'll try this gps.conf thing

Hi all,
Thanks for this topic, just see it, after receiveing my G5 coming back from french LG'service (SBE by Allo PSM) for this problem
Default was : MKGF - GPS out of order. It takes 9 days to come back
Last time (I hope not) try first this solution
Mine wasn't rooted so warranty worked and pay nothing
See ya

Hello. The gps problem is a hardware issue, not software. I had the same problem, but it's now been gone for over a month and so far gps works like it should. There was a solution for bad gps on this forum, it included opening your device and pulling gps antena contact pins, located on the back of the display a bit up in order to make a better contact between the pins and gps antena contact pads which are placed on the inside of back cover, but people reported it only helped fo a day or two, probably because those fragile pins went back to their previous position, and that means bad connection with the antena pads. Now i took a bit different approach... If those f....ing pins are so fragile that putting the phone back together pushes them back down and gps gets broken again afted a day or two, why now make the antena pads a bit thicker. So i did.... I bought thinnest solder i could get (0.3 or 0.4mm wire diameter) to be able to be super accurate with the solder dosage, and i put a little solder on each pad, making them stick up about 0.1mm, maybe 0.15mm higher. I put the phone back together and voila.... Over a month later and no issues with gps at all. It connects to satelites quicker than my wive's G4 which does it super quick.
If you decide to do it with your device be very careful. Too much solder on the pads can cause a shortage in your device. Better to put less, then test, then put a tiny bit more etc. Than put too much and destroy your G5

Considering this phone is on warranty for most people, just SEND IT BACK! No point in finding weird ways of working around poor design from LG... They replaced the motherboard on mine and GPS locks just fine now. My Z force is still faster, but it's less of a pain than it used to.

Well... Weird or not, it works and about poor quality... I'd rather have a phone that needs a bit of tweaking done, than a device that can set my hands or trousers on fire without a warning
