Hi all,
during these months I have had a lot of problems with GPS Fix with my Z3C. These problems occurred after the update to 6.0.1 and I thought that It was a software issue.
In my case, GPS works well after upgrade but It degraded little by little. Applications like GPS Status reported a very very low satellite signal.
Reading every possible forum, I found some guys that explain how to "solve" the problem plugging the usb and powering the phone. An other post specified that the solution was not the "powering" and the fix become better if you lightly pulling the usb connector to you... and It was true! So the problem was not software.
So I opened the phone, disassembled the mainboard from the chassis and tryed to understand what part was involved in the "usb pulling solution".
I found that many connectors (like a little pin) were connected to some particular parts to the chassis (as if it were used as antenna).
In this photo you can see where the mainboard connectors impact on the chassis.
(Sorry the forum prevent me to post link or image)
And this is the specific connector involved in "usb pulling solution"
(Sorry the forum prevent me to post link or image)
It seem that this connector was linked in the edge of connection area, not in the middle as the other connector.
So I gently bent the connector upward and reassembled the phone.
After that, the GPS Status reported a signal very high. Never seen a signal so hight before!
The fix was very fast and the accuracy was constantly under 3mt
I'm not an expert, I'm only a normal user. I hope that this thread can help some other like me that need GPS works very well for run, drive and play.
Thank you for this post - I've been fighting with my GPS for months and am about ready to open up the phone too. Any chance you could post the images externally somehow? It would make this a lot easier to follow for me.

I'm trying to post images but the forum reply me in this way:
"To prevent spam on the XDA forums, ALL new users prevented from posting outside links in their messages. After approximately 10 posts, you will be able to post outside links. Thank you for understanding!"
I'm asking to the moderatos if is possible to unlock me.
I will let you know
Anyway... start watching "sony z3 compact disassembly" on youtube. You need some tool to do this without destroy the phone. But trust me, is not so difficult. In particular, take care about the battery door opening.

I've already disassembled a plenty of Sony phones (from Xperia X10 pretty much to every single later Sony phone that was available in Poland) and the issue with bent connectors is very very common. I also had this problem in my Xperia PLAY where my WiFi and cellular network connectors were bent and were linked on the edges of the plates.

Do you have a connectors map?
Hell. I had the same problem : suddenly the GPS signal became very weak, almost unable to catch any satellites and degrading over time, so since I still had 1 month warranty I sent it to the repair center and they changed my PBA (which is the motherboard, I believe.) It is now working like a champ again. If I were to get the problem back in a few month, after my warranty expiration, I'll definitively try to do what you did.
Thanks for the info.

Unfortunately, no... but I recommend visiting iFixit site where some of the phones are nicely described.
Thanks a milion gepp81!
I ve ordered some replacement parts and tools and I will try to resurrect my z3 gps.

Same with me.
I believe that since we got a new imei number e got new warranty. I have to check the law.

Can anyone confirm this please? It looks weird to me. According to service manual all antenna connectors are on secondary side of mainboard (accesibble without removing battery, just after opening rear cover and removing that frame around, which has 4 screws, if I remember correctly).
It works

It works. All the connectors are on one side of the motherboard (not the battery side). The picture gepp81 posted shows the antenna area where the connectors connect to, so not the actual gps connector.
Thanks a lot!
I had absolutely no GPS signal.
After trying every software tweak / wipe / rom.... (I was hopping it was a software issue) I finally tried your solution, straighten all the little contacts, and now my GPS has a wonderful signal!!!
I destroyed my back cover, but it doesn't matter I prefer that than no GPS
Wow, thank you. I can also confirm this. Despite that official service manual says something different.
Previously zero signal at all (23 satellites with 0 SNR), sometime 1 very weak satellite. Now 9 fixed, another 6 visible. Those 15 doesn't have very strong signal, but it's usable.
I am thinking about using some thin wire to improve it (like this: https://talk.sonymobile.com/t5/Xperia-Z3-Compact/GPS-issue/m-p/1006245/highlight/true#M12642 ).
Another successful story here - gps stopped working, i updated my rooted kitkat to slimm 2.4, opened phone, did the connectors trick, but gps was still dead. Then after few days i checked "Device only" in Location settings and GPS came back to life! Now works with "High accuracy" mode as well

Also had problems with my gps. First I thought it was water damage. But pulling with the usb connector made it work again.
Did the trick with bending the connector. Now I have signal but is is not very strong.
Is there a way to make the signal stronger?
Is the copper strip the antenna?
Can I replace this with another copper strip that works as a better antenna?
Or .....?
If your gps antenna is somehow damaged, you could fix it using silver paint:
http://www.2spi.com/category/silver-paints-pastes/
I didnt try it, but friend of mine uses it to fix broken boards on laptops... Should work in phones too
Same problem. I sent my phone to service. They changed motherboard. Now GPS Works perfect. And my warranty is extended for 2 years, because of different motherboard and IME. Thanks Sony, very good service

Hey Guys,
Well, I'm a bit gutted really! I dropped my XDA Mini S on the floor with the charger in and the connector IN the phone has come apart from inside the phone. The little metal bit is practically hanging out. I'm wondering, if i were to take the phone apart could i re-connect the little part? (I have a soldering iron if thats as simple as its going to be?)
Just wondering if anyone had any guides on how to take the phone apart and take a look at whats wrong?
Any help would be so much appreciated!
Many Thanks,
Tom

Hope this helps.
I suspect you probably broke the socket off, but if you have a soldering iron, you might as well try to get a new mini USB connector to work with.
You might try Pocket PC Techs:

I rang them up about an issue I had (screen on the fritz) and they seemed pretty knowledgeable and helpful.
Alternatively there's a company I found today in the UK. I can't vouch if they're good or not.
http://www.xdarepairs.co.uk/home.asp
Good luck.
Well I also have an issue with my wizzard... the mini jack connector (of the handsfree) is a bit loose.
What I am saying is that it does have a good connection with the rest of the circuit and sometimes the sound of the speaker goes off, then I have to insert the habdsfree and tickle it a little bit until it has a good contact.
? have some basic soldering experience,do you think I should give it a try?
Given my device has been apart too many times for me to admit to I thought I'd crack it open to take a pic for you guys. Not sure if this pic will help for those wanting to do some soldering:
Very large pic: http://farm1.static.flickr.com/216/452691530_f47801708f_o.jpg
Excuse the dust.
Ah! That picture at the bottom is exactly what I needed. The metal but at the bottom (the big sqaure) has totally sheared off....bloody thing. Thanks so much for the info on the repair guides. I may give those repair guys a call if i can't get it to work myself.
Thanks alot you guys
As for you WizeMan, it all depends on if you wish to void your warrenty or not. At the end of the day, I installed WM6 on my device so O2 would give me the finger if i tryed to claim. If I'm honest, I'm getting an upgrade next month so I'm not to bothered if I balls it up! Would be nice if I got it working though....
Lemmie know how you get on

A little bit of a thread hijack but that means it is SIM unlocked.
Let me tell you my news, my friends.
I opened my Qtek 9100 and fixed two serious issues regarding this phone, using... sponge (the one we use to wash the dishes)
1. I put some into the stylus socket (from the thin space it has) and also
2. On the top of the mini jack socket so when i assembled the housing it blocked it from moving (2 of the contacts are no more soldered and i dint have a soldering iron at that time)
Anyway, both operation went ok and my phone is more than fully functioning. Now the stylus is hardly (in a good way) comming out (it first gets longer then comes out).
I wanted to do also the safe singal fix, but didnt find the photos to apply it correclty, so if someone has them, please give link. If you need any info about the "Sponge" Hacks, just post or pm

I'm still trying to get the a new fascia and will probably shove an eraser bit into the stylus spring mechanism to ensure the defect never happens. Also how did you discover the break in the solder joints on the headphones jack? I have a funny situation where the left channel of the headphones doesn't work but I suspected the headphones (the plug has to be pulled at an angle to get any sound out of the left) but now I am thinking it may be the socket itself.
By the way the reception fix pic doesn't load for me either but I unless you truly need it, don't waste your time doing it; I always have all 4 bars and sometimes have 2 bars.

Allright here is the deal.
1. I found out the break in the soldier joints when i opened it. I was really suspicious about it because when i inserted my headphone jack into the connector, i had problem with the contact; the connector was loose and it muted my phones speaker. When i disassembled the phone using the service manual i saw with my eyes that the the joins where f-ed up.
2. I dont really need the signal hack i just wanted to experiment, i have 2.25.11 cingular radio rom and its great.
Btw i suppose you should better use the sponge, because the rubber may wear off but not the sponge...
Thanks for the tip on the sponge. I am going to grab a used but allegedly "like new" body from eBay and also get one of those covers as well.
Here is the Samsung Galaxy S3 (GT-I9300) Service Manual.
Please take a moment to read the notes and issues about this manual in this post.
For some reason Google didn't pick up that post, so I had to re-post here...
Now, if you are brave and happen to have a GT-I9300, you can still help us by posting some
internal pictures, to verify some issues in the manual. If they are good,
some of them will eventually become part of the SGS3 Hack-Pack.
Thanks and Enjoy!
I will be opening up the phone in the next few days due to me managing to damage the sim card holder section(not holding sim card) So at present i have got somthing putting pressure to keep sim card in place. I have a new sim card holder on order so when it arrives i will pull phone apart and take some pictures.
If you have any advice for me before attempting this please let me know via pm
Do you have any experience in this kind of electronics? I mean, are you planning to replace and solder the SIM card holder by yourself?
If you have not done this type of soldering before, I do not recommend it.
If you do decide to do it on your own, make sure:
You are working on a clean workspace
You are well grounded and not wearing wool clothes mixed with synthetic materials to avoid any ESD.
Have the right tools for the job.(Temp controlled SMD soldering iron + flux and acid-free lead-free SMD solder etc.)
A very steady hand with good eyes!
As for the pictures, keep the environment as bright as possible, preferably daylight. Try to keep your PCB on a bright or neutral background. (Bright cardboard is usually good.) Inspect your pictures and make sure you can read the text on the smallest chips. (The big ones we already know about, its the smaller ones that are difficult to navigate around.) Make sure the pictures are well focused.
Good Luck!
From looking at the pictures I was hoping I don't have to solder the sim card slot in. It looks easily replaceable as it looks like it's just a connector and not soldered
Replaced the sim holder. My camera wasn't good enough to get focus of the smaller chips however it is very very easy to take phone apart. And I guess Samsung are expecting issues with sim slot so they have fixed it using one screw and connected to board using a pull off connecter.
Just in case anyone else is interested the sim holder/sd holder cost me £20, delivered.

Hi guys,
Here is my contribution to da community, hope so it helps.
h t t p s : / / docs . google . com/open?id=0B9lrf7AWQW7ETjRZTkFXb1luN0E
On image 20120616_150200.jpg you can see the region jumpers. The images are of a live demo unit - everything works besides the GSM/3G data. Haven't tested to see if the NFC is working.
The real unit has some more antenna connector. The demo one does not have PBA /printed board antenna/ the ANT102 and ANT103 as well as the capacitors and the coils u may seen them market in red cycles (ANT102, ANT103, C102, C191, L103, L102) there is no room on the MOBO for C192 /or at least I can't find its place/.
Thanks.
^^ Here is the link for above! (Thanks!)
Hi again,
I can confirm that the NFC is working on the live demo unites. According to the original S3 user manual the NFC antennas are build into the battery back.
I still can't figure out what is the "W2" antenna connector for. The Live demo unit has no connector soldered to the motherboard and also lacks the small PCB antenna with the white coaxial cable. Some ppl claim that the W2 is for WiFi antenna, but it is not, because I got great WiFi connectivity tho the lack of such PCB antenna. I can only confirm the WiFi working fine, under "G" type of WiFi networks. The openWRT firmware of my current router has known bug and I can't bring up "N" standard in air, to check if the PCB antenna is for "N" type of WiFi networks.
I also did some testing to see if the PCB is for GLONASS or GPS, and it seams that this PCB antenna with the white coaxial cable is not for any of these services. That's why I think it might be for wifi "N" or 3G data/networks. Donno if the 802.11n requires a separate antenna.
^^ Please post a link to a specific image, that clearly show the connector(s) you're talking about.
Hi I have a live demo unit to, so I think I can help about this =).
I can't show you the mainboard back because I' m new user... xD
I don't really know what you mean with NFC (sorry, I'm not really good with english)
But
W1 is a GSM external antenna conection
W2 is a wifi external antenna conection
And the white wired antenna is for wifi to.
After thinking a lot, if you conect an antenna to the GSM antenna conection (external or the internal lacked in Demo unit) you probably can't use phone function.
That function probably was crippled by software or because demo units don´t have imei maybe o.o.
The only thing I need to try is to connect a microsim to the phone
No one has any insights ???

Samsung galaxy S3 i747
i have a Galaxy S3 SGH-i747m that has been water damaged and given to me so i could try and fix it. I can take pretty much any pictures you want, have openned the phone a couple times now to try and clean it up.
My problem is that the works well, it starts up, unlock the screen, plays sound...but the screen is off. Now at first when i was "playing" with it the screen would flicker on and off to show me the battery charging logo when it was plugged in. I've cleaned the phone and all flex connectors with some products. the phone still turns on and works but my screen is off. It detects the touch since i can unlock the screen ( it plays the water sound when i slide my finger on the screen) and speaker works when i boot it up (little booting sounds).
I was thinking there might be a small fuse on board for the screen backlight and that could be blown. I was also thinking my battery might be damaged and is not giving the phone the right voltage to the right connectors or something so i have ordered a new battery on ebay (under 4$) and am waiting for it.
Anyone has an idea to some specific things i should be looking for ? only thing haven't disassemble is the digitizer from the framebecause doing so would surely break the glass. It bums me up a bit since there are some electronics behind the frame that could have been damaged by the water that i couldn't see.

check if you can see anything on the screen, use some extra light, torch for example.
if so - then its more likely that the LEDs in the display panel are damaged, since it flickered, as you said. also could be the driver circuit for backlight. Clean connectors for display panel, use magnifier, or better microscope to check for corrosion. use IPA to clean or scrape off the corrosion.
also - maybe this is not the right place to discuss this.

I have identical symptoms with my i9300.
1. Water damaged
2. Dried in a can of rice etc over several days
3. Cleaned under sim card, lots of debris there, looked scorched, I cleaned with alcohol and a brush in an ESD protected environment.
4. Re assembled, the display briefly flashed on, and showed the expected "Battery is low, an d No Sim Card" then powered off.
5. Now after charging the battery and emplacing my sim card, I hear the proper musical tones when the phone boots but the screen doesn't light.
Where you able to get the screen working?
I am going to try a more throughal cleaning and I will try viewing the LCD under a more power full light.
I too worry that just getting the LCD screen replaced might not work; the screen may be fine but the mother board LCD power supply might be at fault...
I will keep you posted and keep an eye on this forum to find out how to fix this.
This thread has served its main purpose.
OT discussions are prevalent.

!!! 25+ ESTIMATED SUCCESSES!!! (Either reported or from thanks on this post)
_____________________________________________
For TL;DR - start at [[ WILL THIS HELP YOU? ]]
This ABSOLUTELY fixed my AT&T Note 3's GPS. However:
:::: DISCLAIMER :::: I had an unusual chain of events leading up to this fix. I hope it fixes your Note 3's GPS, but there's really no way to tell - unless you decide to try it. It may not help you at all. So, what have you got to lose? Well, take a look at [[ WILL THIS HELP YOU? ]] and [[ RISKS ]].
[[ INTRO ]]
If you're here, most likely your Note 3's GPS doesn't work, and you're desperate like I was for a fix. Here's the chain of events that led to my fix:
1. Got AT&T Note 3 - **out of the box** it had the 'blurry' camera issue, but outstanding GPS (consistent 3 second satlock).
2. Sent Note 3 in for Samsung Warranty Repair to fix the 'blurry' camera.
3. Samsung fixed the camera.
4. Disappointingly, Samsung broke the GPS (by bending the 'leaf' pin circled RED in my pic below, I assume inadvertently during reassembly).
5. Got Note 3 back - camera fixed, GPS broken by Samsung.
6. After observing an iFixit teardown, I followed this chain of logic: A - Since Samsung replaced my camera, and B - the camera is separate from the main board that the GPS is on, then C - Samsung must have only replaced the camera, and left the GPS alone. D - Therefore, Samsung did not replace my exceptional GPS, that, sadly, is now broken. E - Something else must have broken the GPS. F - I read a thread suggesting that tightening the 12 screws on the back fixes the GPS, then G - I decided it's time to check on the leaf pins after looking at the iFixit teardown. Below is what I found.
[[ WILL THIS HELP YOU? ]]
Hopefully. I have no idea. Maybe. Decide if the [[ RISKS ]] are worth it to find out if one of your 'leaf' pins are bent or damaged (mine was bent by Samsung Warranty Repair, as explained above).
[ 1 ] Yes, if one of the 'leaf pins' is bent, dislodged, or otherwise not making contact.
[ 2 ] Yes, if one of the contacts that the leaf pins touch is oxidized. (Remove oxidation by scraping it off.)
--- Thanks to evilpotatoman for reporting this fix! ---
[ 3 ] Yes, if one of the 'leaf pins' is squished and is not pressing hard enough against the contact. (Bend "leaf pin" outward to make tighter contact.)
--- As suggested by evilpotatoman ---
Also, perhaps adding a small piece of stock paper under the offending leaf pin will make it keep contact better. ( !!!! Be careful - don't add too much paper, which could stress the pin or contact !!!! )
--- As suggested by superdookie67 ---
[4] Yes, if a screw is loose. This may happen if you remove the back cover frequently, which loosens the screw that keeps a solid connection between the leaf pin and contact near the back cover fingernail hole.
--- As suggested by yedidi2006 ---
Let's be honest: since Samsung Warranty Repair dislodged my Note 3's leaf pin, isn't it plausible that a maybe even a few Note 3's shipped with bent leaf pins?
I'M WILLING TO BET YES. So please reply and let everyone know if this fixes it.
[[ RISKS ]] (Honestly, this is a pretty basic procedure. But here goes)
1. Potentially voiding warranty, though I have no idea how it can be proven (put some new Loctite on the screws afterward if you're paranoid.)
2. (Only a risk for those who are completely careless) Potential damage to internal equipment.
3. Losing 30 minutes of your life. Personally, I love tearing stuff apart whenever I have an excuse, so for me this wasn't a risk.
[[ INSTRUCTIONS ]] (See attached pics for details)
1. See your favorite teardown site for even more details. Remove the back cover, stylus, SIM, and microSD.
2. Remove the 12 Phillips screws on the back. They are sealed with Loctite, so don't damage your phone with too much force.
3. !!!Carefully!!! remove the inner plastic shell (clipped in).
3a. !!!Only lift up!!!, perpendicularly from the screen to avoid damaging the leaf pins.
3b. !!!Take your time!!! Gently open around the edges until all edges and clips are loose.
4. Observe the leaf pin locations shown below.
5. Samsung bent my leaf pin circled in RED below. This one is clearly related to the GPS, because bending it back restored my GPS to perfect functionality.
6. !!!!Extra Carefully!!!! bend the leaf pin back into position, if you find a dislocated leaf pin.
7. Replace the inner plastic shell, making sure to not damage the leaf pins.
8. Replace the 12 screws (with new Loctite, at your discretion).
9. Obviously, replace the SIM, microSD, stylus, and back cover.
10. Fire it up.
11. MOST IMPORTANTLY, reply back if this helps - maybe this is a fix for many of the Note 3's that shipped with terrible GPS reception.

Nope, I looked in and my 'leaf' pins were all properly shaped. I even slightly bent it to look more like yours, and still having GPS issues.
Sorry to hear that didn't fix it for you. Thanks for posting your results though.
If someone is feeling ambitious (and somehow doesn't care about their warranty), the other thing I was thinking is to clean off / polish the contacts that the leaf pins touch, but that's almost certainly a warranty-voider. Not to mention it could possibly damage or ruin the contacts.

Switched my rom back to stock NB4 rooted, having no gps issues now (if I remember, it worked just fine on NB4 before). Bent pins may be a problem for others though.

Interesting, well at least it's working again.
I'd be stoked if someone else fixed their GPS because of a bent leaf pin, since it's such an easy and decisive fix.

wish i had seen this earlier. I had mine done just like what you did plus the pins from the backside of the motherboard. mine wont lock unless i am outside and had clear view of the sky (no signal if inside the car). and had to conclude that its the hardware and not the software. after doing all of those pins. i got lock in less than 3 secs!
damn note 3.
also, i had to spray those pins with an electronic contact cleaner before I put them back together

Is there a fix for the compass not working correctly? Sometimes when I'm driving, it makes it look like I'm traveling sideways. This is on GoogleMap. My GPS has been working fine since the first day.

My guess is that this fix should work for any subsystem that uses one of the leaf pins (of course only if said subsystem has a bent leaf pin).
We'd have to determine where the compass is located and if it uses the pins. Otherwise, I'm not aware of a compass fix. Mine has exhibited that behavior too. I'll report back if I find anything.

I was suffering from little to no GPS fix. Opened it up per your instructions to find that my gps pin wasn't bent, but the terminal to which it contacts was oxidized. I bent the pin up to ensure a tight fit and I marred the terminal with a razor to remove the oxidation. My GPS works flawlessly now.
would anyone know among those pins, where exactly is the gps antenna connected to?
ok nevermind. i figured it out. its the 2 pin at the top right (where the volume keys are)

This ABSOLUTELY fixed my AT&T Note 3's GPS. However:
:::: DISCLAIMER :::: I had an unusual chain of events leading up to this fix. I hope it fixes your Note 3's GPS, but there's really no way to tell - unless you decide to try it. It may not help you at all. So, what have you got to lose? Well, take a look at [[ WILL THIS HELP YOU? ]] and [[ RISKS ]].
[[ INTRO ]]
If you're here, most likely your Note 3's GPS doesn't work, and you're desperate like I was for a fix. Here's the chain of events that led to my fix:
1. Got AT&T Note 3 - **out of the box** it had the 'blurry' camera issue, but outstanding GPS (consistent 3 second satlock).
2. Sent Note 3 in for Samsung Warranty Repair to fix the 'blurry' camera.
3. Samsung fixed the camera.
4. Disappointingly, Samsung broke the GPS (by bending the 'leaf' pin circled RED in my pic below, I assume inadvertently during reassembly).
5. Got Note 3 back - camera fixed, GPS broken by Samsung.
6. After observing an iFixit teardown, I followed this chain of logic: A - Since Samsung replaced my camera, and B - the camera is separate from the main board that the GPS is on, then C - Samsung must have only replaced the camera, and left the GPS alone. D - Therefore, Samsung did not replace my exceptional GPS, that, sadly, is now broken. E - Something else must have broken the GPS. F - I read a thread suggesting that tightening the 12 screws on the back fixes the GPS, then G - I decided it's time to check on the leaf pins after looking at the iFixit teardown. Below is what I found.
[[ WILL THIS HELP YOU? ]]
Hopefully. I have no idea. Maybe. Decide if the [[ RISKS ]] are worth it to find out if one of your 'leaf' pins are bent or damaged (mine was bent by Samsung Warranty Repair, as explained above).

Where did you go? To an AT&T store or bestbuy?
My phone had no GPS issues at all until a couple of days ago after I dropped it flat on its back (with a thin cover on it) and picked it up with no scratch on it. Now I have NO GPS at all (I'm not sure it is because of the fall or something else. It fell several times before and it didn't mess my GPS). I tried every single GPS fix app in the Play Store that used to actually solve my GPS issues and nothing. I downgraded from KK to JB thinking it might have been KK that was causing the problem and also nothing. Now when I try to use my GPS, it hangs on "searching for GPS" forever. I'm thinking of re-flashing stock and un-rooting to take It back to them (I need your advice on where I should go, please). I don't want to start disassembling my phone first.
Thanks man.
from my 3rd beast of a phone..!!
I'm genuinely glad to hear this has helped at least 2 or 3 others! It was such an annoying issue for me that I hoped it would help someone else.

Thanks for reporting this. I actually bent the top left pin (where the power key is) to fix mine, so it would appear that either the top right or left pins could be causing issues for people.

I shipped my Note 3 to be repaired by Samsung Warranty Repair somewhere in Texas (free of charge, since it's still under warranty) (if that's what you're asking - I didn't get it repaired at AT&T or BestBuy). I am by no means an expert on this, but from what you've described my first guess is one of your pins got dislodged somehow (presumably from the fall). Honestly this procedure isn't overly difficult, but I understand if you don't want to crack open your phone. Until I did open my phone though, I was having nearly identical issues as you are (hanging on "searching for GPS" , the GPS Status app could only find 2 or 3 satellites instead of the usual 12-19, etc, etc, etc).
Samsung Warranty Repair bent my GPS pin, causing it to malfunction. While I sincerely want to recommend that you send it to Samsung to fix, just be aware that things can go wrong - I speak from experience.
Thanks again for everyone's responses!

I appreciate it, man. I heard from some friends that it could be this http://www.androidpolice.com/2014/0...-services-are-experiencing-outages-right-now/
So before shipping my phone, I'm going to wait a little bit longer to see if this is the issue. I still have a long while on the warranty
I would like to say this fixed my GPS on my AT&T Note 3.
I didn't have to un-clip the complete back, just the top left section enough to see the two antennas.
Now my GPS works normally.
Funny thing is my Note 1 had the same problem, which I fixed in the same way over 2 years ago..
What I am guessing is that when we put pressure on the phone we squish the antennas down so when the pressure is relieved they are no longer in contact.
Seems to be a design flaw in all generations of the Note phone.
Samsung should change how this connection is made, as the flaw will continue to occur.
thank you for the post!
Itworked but only for a few minutes

Unfortunately it didn't work... I also found that my note 3 is a little different to your photos where the two leaf-pins are mounted side by side.
I followed your procedure, found what I think must be the same leaf pins you refer to, but they didn't seem to be bent or misshaped. I bent them up slightly anyway,since I'd gone to so much trouble to tear it down, before reassembling the device.
When I first switched it on I thought I'd had a win: Using the 'GPS Status' app I quickly acquired 4/ 23 satellites, where normally I see 0/23 (or 0/xx) the xx number varies.
That soon increased to 11/ 19 and I thought yes its fixed AT LAST!!
For once I was even able to locate my device in Google Android Device Manager too - it rarely ever works. The only one that does is 'Where's My Droid' as it can find it using the WLAN and the mobile phone towers that my SIM is connected to. It appears that Google's ADM MUST use GPS only, because whenever Where's My Droid finds it via GPS (which isn't too often), Android Device Manager also works (finds it ok)... It was this constant failing of ADM which eventually brought me to the conclusion that the problem is to do with GPS (I've tried EVERYTHING to fix this over several months) and how I eventually found your post, which unfortunately doesn't seem to have helped me.
It does seem a bit odd though, that it worked for a few minutes after firing up the phone.
I just wonder if some component is failing once it reaches a certain temperature?
If so, I might was well forget it (warranty void - had to remove a sticker that was over screw # 12) and buy a new phone, but NOT a note 3!
I checked this with the recent gps trouble I've had with my tmobile version. I noticed mine were smashed down as low as they could be. Pulling them back up a bit, my gps does seem to be better now. I was wondering, would sticking some stock paper or anything under them help to keep them raised and connected to the other side?
And thanks so much for this post, I had been working on this problem forever.

When I wrote the above reply, I didn't realize that I was too far inside my house (under it's steel roof). As soon as I went outside or even near a window it all worked great and still does, but I guess no GPS works too well when its effectively shielded under an iron roof...:laugh:

Glad to hear it worked! I agree, perhaps sticking a little paper under the pin that's causing trouble may help it keep contact. I'll add that suggestion into the original post.

Good deal! I'm in the same situation - under a steel roof. Basically, my house similar to a Faraday cage, blocking out almost all radio communication (cell, AM/FM, TV, you name it.)
Sounds good, looks like we've got about 5 successes so far!
YES! I had absolutely no GPS, popped open the phone - the leaf was already bent back as in your "after" picture, but I just propped it up to get better connection, and now I finally have a GPS signal, 13/25 satellites within 30 seconds of my first test. Thank you so much for posting this.
Like the title says I now have little to no wifi signal unless stood next to the router?
Can anyone help me out am getting really cheesed off with this.
thanks in advance
Checked for loose connectors? Does wifi improve if you remove the cameras?
Was perfectly fine, before I did the camera, checked the conector the little point bit snapped off but not the ful connector so I am still able to lift it up slightly?
Are you referring to the centre pin?
no the little connector on the oppisote side of the bored
located here in the green ring, the whole connector is still attached all tho a little bit on the top has came of no bigger than a half centimeter
Maybe the connector is not making proper contact with the back casing. Maybe add a bit of solder to the gold contact to raise it up a bit to it makes better contact?
Would adding solder not damage it?

Sounds to me like the device was opened to replace the camera, and it could be something easy to fix. Fix step open the device, and check that suckers WiFi Antenna wire....looks the same as a Laptop WiFi Antenna Wire, except smaller and shorter, it may be disconnected from the logic board connector location, or the wire is broken or damaged.
Adding a but of solder may work as long as you use low-melt solder, a very fine tip iron, and you do not let the solder flow to other parts of the board.
I suppose the alternative would be taking it to a cell shop to see if they can fix it.
I have Samsung i9505l updated to lollipop via OTA after updating All the sensor stopped what does it mean is Samsung killing their devices via ota's i said to my friends that it's hardware (sensor Hub) problem! and he was saying no it's software problem after downgrading to Kit Kat... everything works fine I lost $30 bet on it.! poor Samsung ! so the main question is there anyway to upgrade to lollipop with working sensors?

Hi to all,
sorry for my english but i gonna try to explain how to fix GPS in LG G5:
1. you need to unsoldering 2 mhf rf connectors like you see in pic1.
2.after that you need to solder 2 wireup cabels like you see in pic2.
3.in the end this is how it gonna look, like you see in pic3 and pic 4.
Good luck!
Where to solder the two cables on the other side?
Inviato dal mio LG-H850 utilizzando Tapatalk
No where, they just attached to the frame with duct tape.
Can you explain a bit more, what are pic 1 and pic 2 are are you removing whatever is there. It look like pogo pin not sure...
In pic1 you see mhf connectors\pogo pins as you call it on the board as they comes from the factory. in pic2 I unsoldered them, so this is how the board looking like after I removed them. I marked with the yellow dots where I solder the wireup (wireup is marked in red).
I understand now that you are using a thru hole RF connector and place a wire that act as an antenna, I wasn't able to locate where is the normal antenna and why is it not connecting right at the first place. it seem that the RF connector is not used normally so it is probably there only for factory test purpose from the ifixit teardown pictures.
https://d3nevzfk7ii3be.cloudfront.net/igi/KEVL1LUslTEBSoVO.huge
What kind of improvement did you get on the GPS, mine is working but not great so I am tempted to fix it but I am still not understanding what the fix does for now as I have to extrapolate that you are actually making an antenna with the wire. Lenght should matter quite a lot then, did you make a few test with various length to came up with the fix you documented.
There's another thread with a gps fix, but he's only putting more spring into some pins this fix may be better on the long run!
Thanks for the explanation
Before fix I barely get gps fix, I needed to wait about 5 min to get fix, after that the gps was not stable at all, it always get 5 satellites in max.
After fix I get gps fix after 10-15 sec, and I always get between 19-21 satellites, and gps works stable without any disconnections.
About the wire length, I didn't tried various lengths.
Getting yourself familiar with the insides always a good ideal. There's a good app in the play store called 'iFixit'. It's helped me with a lot of different devices opening up.

How bout does the iron need to be? What kind of solder should I use?

The iron temperature actually depend on the solder you use, you ideally need something that melt fairly low like 63/37 alloy 63/37 Sn-Pb used principally in electrical/electronic work. 63/37 is a eutectic alloy of these metals, which: has the lowest melting point (183 °C or 361 °F) Other eutetic alloy without lead may be availlable in your area. You also need the type with Rosin flux not acid or water washable.
You will also need a small tip at the end of the soldering iron and a good magnifier, but working with multilayer PC board with no experience can easily lead to catastrophic failure.
I would recommend you start with easier mods than this one if you are not familiar with soldering and general soldering on PCB, this is a fairly easy thing to do for someone familiar with this type of work as the hard work is to figure out what to do
Maybe find a local cellular repair shop and ask them if they can do it for you.
@slavush - thanks for the info here. Can I ask how you determined which connectors were related to GPS? Any documentation about the PCB or similar?
There are different people mentioning different pins all over the G5 for GPS. I have opened up mine 3 or 4 times now, each time finding success for a short period. So I failed to determine which were actually the ones to focus on.
In your opinion, instead of welding the cable, would it be possible to plug it into the connector hole?
I tried to put the cable in on the phone as in the picture without connecting it. But when the cable is inside the phone does not turn on.
My gps does not work. It does not even hook up to a satellite

How about now? Is this fix still working?
Also curious about. Any fix that really works?
I already fix my GPS without soldering.... But in order to fix it you should disassemble the G5 and look for 3 pins....
Sent from my LG-H860 using Tapatalk
I don't think the 3 pins mentioned are concerned with the gps. I tried myself lots of time to raise them up and the gps for a while worked, but, now i broke those 3 pins. No more volume...but gps works...extremely bad and slowly as before. If you look at the flex
you can see it is only related to the volume buttons. So...I don't have any idea.
About this soldering fix.....why shall I have to unsolder those two things?
the 3 pin worked for 6 month... and never worked again, 3 is crashed a bit now, also, i added aluminum foil to the 3 min, so volume up down still work.
I was going to try this fix mentioned here, untill i open the phone and found how Small the POGO pin is.
seems quite hard to remove as there is so many electronic around it.
i am going to just Plug in the cable and TAPE it in place and see if it can work this way..
Update:
Interesting enough, the phone refuse to turn on (with the 2 cable TAPED over the pogo pin. ) it just wont turn on.
Now, i removed the wire from lower pogo pin, with the upper remain. and the phone can turn on.
will go test the gps and see
@slavush, I see that you are from Israel. Any chance you're from Tel Aviv? I could use some help with this.
@scoobychau, did you get success in gps signal improve?
How did you it ?

Hello scoobychau,
My LG G5's 3rd pin is also crashed, broken, destroyed. Can you explain me more about how you fixed it with aluminium foil ? It's my girl friend's phone, and I am so sorry having broken its volume buttons' spins or/and GPS feature.
Thanks a lot for your answers.
Concerning the soldering, I am so bad that I can't imagine doingit myself...
