I have an inspire running coredroid v8.1 and I cannot get a gps lock at all, even if I let it sit outside for 10 minutes...
I have reflashed the rom several times, and even tried the newest versions of virtuosity and cm
I have followed the video to pull the phone apart and I'm positive the gold pins are making connection
I have tried angel death's patch
I have ran gps status and cleared and re-downloaded in a-gps settings, ran gps test, and ran faster fix
I have tried the trick where you pull the sim out and get a lock (I still get no lock even with no sim)
I've looked everywhere and tried to do all the research before posting a new thread, but I just can't find anything else and I don't know what my problem is...
any insight would be greatly appreciated
EDIT: Also thought I should include that I have flashed radios 12.41.60.19_26.06.04.14_M, 12.54.60.25_26.09.04.11_M2, and 12.62.60.27_26.13.04.19_M with none making a difference
Sorry to tell you but you might just have a bad thing piece of harware. I started a thread a little while ago called "GPS Last Resort". I tried everything... And I mean Everything! I was told that there were "known" hardware issues with the Inspire. So I un-rooted and returned to a "stock" state and went through the PITA process of getting a replacement.
Once I got my replacement, it was a night and day difference. My new one locks in less than 15 seconds with 5-4 meters accuracy.
Don't drive yourself crazy. If it is still under warranty, get it replaced.

did your phone have any other signs of being defective or was it just the gps? I mean, the phone is great except for this! No boot loops, force closes, glitches, or anything...
Also, if it's just the antenna, could I buy an inspire with like a broke screen or something off ebay and just switch them out? Do you think that's a viable option?
Sorry it took so long to get back to you on this...
You may not even need to replace the antenna at all. When you pop off the cover for the LED camera flash (this is also your gps antenna) there are two little spring like clips that are the contacts for the antenna. If those contacts are not making a good connection - your phone will just keep searching for signal. If you are brave enough - you can pop out the antenna and carefully bend out those contact clips in order to make a better connection.
I was hesitant to do this myself - and sense the phone was still under warranty, I got a replacement.
Sorry again for the delay - hope that helps if you have not already found an answer.

Yea be careful with this. I decided I'd go ahead and pop off the camera cover to readjust my gps antennae contacts and ended up breaking the cover. ~2cm crack just under the flash, which raises up the cover enough that the contacts won't make contact at all unless I'm applying pressure that only Thor could exert on the cover.
side note - 2 weeks after I did this my screen shattered.
Haven't been having much luck lately..

Ouch!
That is pretty much why I decided to go for doing the warranty replacement
I did the warranty after trying to remove the gps antenna because it still didnt work after i did that. The sent it back working !!!
Anybody else's gps connectivity generally crap? Seems to take for ever to connect then struggles to keep a connection.
Any known software conflicts? Running stock 2.35 rom.
No trees, walls, flying saucers in the way and Tried various gps info and fixer appear but to no avail.
Starting to really p*ss me off now.

Yes, happens to me too. expecially when i go for walks. It takes reaally long time to load. Use Gpsfix ( Google it, Not able to post link because of post count) . It makes to process a lot faster.

Be warned that gpsfix adds air push adverts to your phone. You may want to also instal add-on detector to find and remove them.
OP: Are you using a case? You may find that without root, you can't change the agps server location (mine was set to Asia by default) so it takes a while to lock pulling satellite info via 3g from the other side of the planet!
GPS Status and toolbox (which doesn't need root) forces an AGPS data download on startup and might help. Make sure 3g is on.

Have observed that the GPS fix times are ROM dependent during my journey through many many excellent ROM's available for Desire S. I have even tried the AGPS fix which is recommended in the Dev section which was indeed helping to get a faster fix but the fix wasnt stable afterwards, especially while using apps like endomondo sports tracker..
The first ROM I saw that the GPS was excellent was in MIUI (GB) - without any AGPS or any other market apps or hacks I began to see a fix within 20 secs. Now, I'm presently on Reaper 2.2 (without AGPS fix) and the GPS continues to be excellent (<20 sec fixes).
I'm using ice cold sandwich with GPS+agps fix and find satellites in 3 seconds
Sent by my fingers to your head.
GPS fix issues can be as simple and HW-related as bad contact between the phone cover that includes GPS antenna (I guess it's the lower cover, but it might be an upper cover too), and the golden connector pin on the board. If you test all possible SW workarounds and they don't help - try to locate the antenna and make sure the connection is firm. Look for Vibrant GPS problems, they had such problem in the early batches.
For me the thread AGPS Patch Desire S 3.1 & 2.2 | GET BACK TO RAPID GPS LOCK, CAN LOCK ONTO MORE SATS helped a lot to get rapid GPS lock. Though, I'm not sure if root is needed for all installation methods. Good luck!
P.S.: The described patch is allready included in some custom roms like Endymion.

The GPS and WiFi antennas are in the upper (camera lens) plastic cover, and, yes they use sprung pins to (hopefully) make connection. The phone antennas are in the lower (battery) cover.
I have found that many types of case massively deteriorate GPS reception of my phone. What puzzles me is why some users seem to be entirely unaffected; it's almost as if individual phones vary; even as an experienced engineer I cannot expalin it.
Since cases create mechanical pressure on the phone body and the contacts are very sensitive to their cover bending (they usually have a very light touch), it might be one of the reasons for reception deterioration. Sometimes even a hit of a falling phone can either destroy reception or improve it - saw it happening live on friend's Desire HD, it was very funny to see how the GPS that wouldn't lock properly for weeks, after the phone fell, started locking in 5 sec all of a sudden. Pure plastic cases shouldn't matter for reception otherwise, or at least I can't think of how can they possibly interfere.
By the way, Desire S' GPS is a bit on a weaker side - I compared it side-by-side to my MT4G, and it's always several lock seconds and a couple of locked satellites below. It should be plenty powerful for a good fast lock, though, and that's why I suspect disturbance on the HW side, rather than SW misconfiguration.
now that you guys are talking about cases, I was using a case mate barely there case before... long time ago gps fix was on the slow side (around a min).. but somewhere down the line of moving across ROM's I moved to MIUI GB (with the case still present) and the fix improved (without any AGPS patches or GPS fix apps).. now I dont use the case and have moved to Reaper CM7 based ROM and the GPS fixes are brilliant... looking at the build of Desire S I dont think that the contacts for GPS, wifi or phone antennas are at fault or can change with just a fall.. I can't pin the problem but I definitely feel removing the case has helped the gps fixes.

Seems legit. By so far I am experiencing also constant GPS problem. It really might be the problem. I will make a try and let here know how it goes.

Clining contact did not help..
adding some wires to the antena (made some improvement)..
Than i orderd "new antena" for 8 eur form "Taiwan".
no may fix quick and with 12-18m an i does not lose fix anymore..
(and now i have working gps.. after 1 year of trying roms and waiting for better radio firmwares)

You have first version of gps antenna which has been silently improved..
I bougt new antena (upper cover) and wifi antena is printed the sesame number, but gps antena has an number increased by 10. (which by my means, mean new version)
And with "new antena" i have reliably working gps now.
(htc service (here in SLO) wanted th have the phone one service for 14 day-s thats teh reason i didnt apply for warranty repair)
on stock rom gps is really slow..i have that experience before,actually one of the reason i rooted mine...now,got gps locked in less than 15 minutes...(my gps always turn off,on when want to use navigation only)

That's awesome! Could you please share a link to that item, please? I am really interested in that. I am still fighting with GPS. Sometimes it works, sometimes it don't...
I dropped my S3 on the floor. There was no damage, but GPS stopped working accurately. I tried GPS fixes, but those did not work for me. Eventually I discovered that it was a connector problem between the GPS and the antenna.
My fix was to:
remove the battery cover, battery, sim.
unscrew 10 screws and remove the back cover.
remove the speaker assembly that also holds the gps antenna
the GPS antenna is on the top left of the speaker assembly.
make sure the gps and antenna connectors are not broken and clean, and screw everything back in snug.
Hopes this helps someone.
Were there any seals to break so that your warranty could be voided? I might look into this. My gps works most of the time but should lock faster than it does sometimes. I shouldn't have to hold it to the Window in my truck.

so call me crazy, but this might have fixed my gps. ive talked about having gps issues in the other threads (gps patch thread), and decided to give this a try. take apart my phone, detach the speaker assembly, and put it all back together (there is that one connector but are you sure its the gps and not the speaker?. ive had issues since release of the phone and am now getting gps lock in my house which was impossible. on the streets google nav isnt throwing me off either.
at first it didnt make much of a difference but after a while it started locking on. Id like to reiterate that ive tried lots of solutions: roms, apps, the gps patch in the development sub forum. Who knows if any of those kicked in, but it sure is coincidental of tearing the phone up lol.

So, "only" 2 months after this was posted and I was the first to reply to this, I finally found my micro screwdrivers and I tightened the screws under the back cover, and my gps is ridiculously better. Just before tightening the screws, it took about 15 seconds to get 1 or 2 satellites to lock. Immediately after, I retested and had about 18 in 5 seconds in the same seat inside. I feel like a moron for taking so long to do this. Thanks again.

There seems to be a common issue with these phones and the loosely connected GPS antennae. Many have been using this fix as opposed to sending their device in.

Even disassemble instruction videos floating around. Don't be scared, crack that beast open :laugh:
Lol this is awesome. I've been reading about people with gps problems tightening their screws all week and it actually working.
Now I didn't really have gps problems to begin (always instant lock outdoors. Indoors not so much) with but I thought it would be interesting to take a look at em. So I tightened them just a bit and now I get signal in my office on a rainy day. I use to never get a lock at my office. Awesome.
Still don't get a lock in my apartment but still a noticeable improvement.

Confirmed working! I should see this earlier! For half a year I traveled across the globe, I spent countless times on my gps issue, I didn't remember it had problem due to a dropping but it just act so bad from the beginning. I tried all kinds of roms, cleaned all kinds of data/caches, tried all kinds of patches. None of them works! I thought this model is just bad at GPS.
Now I simply tighten some screws and it works fantastic than ever! I'd like to quote someone else because it also happens to me: my gps is now so powerful that I can lock gps even inside the room in a raining day!

we should let more people know this, maybe by changing the title. Because for me, I didn't remember about dropping, so I didn't think about to read this thread before.

Hello. i have a question. I have a problem with my mate 8. It's that that my GPS is not working (i don't get a GPS fix). I've sent my phone to the repair shop with guarantee, but they refused to fix it couse i have 2 slight dents in housing and apparently that is what is couses the GPS problem. (one dent is in area of volume buttons and the other is where the charging port is). It's really the dents that can couse this, or is the GPS itself? I could probably change the housing myself (they want me to pay 110€ for replacing it), but how is with replacing the GPS module itself? is it even possible? thank you in advance
its called an SoC (system on a chip) for a good reason, namely that the whole system is built into one chip or the same motherboard. so ud basically have to exchange the whole mobo ^^ maybe its just a bad gps antenna contact though...how did u get those dents?
Sent from my Huawei Mate 8 NXT-AL10
Ok, that sucks actually then
Is it possible to figure out if the gps is bad without changing the housing first? I tried AndoiTS GPS TEST and i get AGPS in orange. Does that mean that module is fine? (I added a screenshot).
Oh, and I've got the dents whit dropping my phone -.-
And another question. Where is the actual antenna? Or is the whole housing that works as antenna?
Hi. I bought the phone on the 8th October 2016. GPS was fully working. On the 10th, I updated as there is an update showing on my phone. After the update. I cannot get any GPS signal at all. This is a bad update.
Flash
I had same issue after I incorporated the KANGvip tools into AL10369 , just flash the cyst from another ROM like b200 or similar. If you don't know how then flash ROM to a working Rom with GPS. Extract the custom backup from twprp. Reload the nonworking ROM and flash only cyst and boom cops can find u after via gps lol

thanx to finding this thread i kept on searching
i recently changed the screen on my phone and since gps failed completely (wifi also seemed to be lesser)
as the phone lays on the screen, the copper nipple in top left corner is the contact the gps antenna has to make with the case.
i placed some paper beneath the element holding this niple, thus pushing it up - BINGO
i get a 3d fix in no time like before
also wifi connection improved
Where is this nipple? https://d3nevzfk7ii3be.cloudfront.net/igi/BPviD4orcNjWNIdi

Mate 8 GPS fixed !
Finally, after weeks of researches & tests I found the "nipple" or copper pin !!!
It's indeed the one on the top left once the screen is on the table. Either you find a way to put it back in position... without breaking it (the best way is probably with your nail) or you just put some Aluminium (a tiny sheet of aluminum folded several times to get 1mn maxi alu to allow the final winding) in the rectangular "hole" on top right (opposite) of the metal cover of MATE8.
I discovered the "right pin" while testing to put a small aluminium foil on several places of the main board (once opened naturally) AND using GPS TOOLS (playstore) ! you have to wait several seconds to get the signal or at least orange dots on the "radar". Better to test first such tool first with a smartphone where the GPS is working fine and compare both phones while changing the place of the aluminium. Nevertheless, I hope you would not have to repeat my tests as I will clearly show the right "copper pin" in an attached picture ...
Hoping that helps.

Check water sticker on botton of sim slot
I had the same issue with a board i fitted to G930F bluetooth wasnt working nor wifi for no apparent reason i went through absolute everything firmware wise and system wise and couldnt figure out what the problem was i then removed everything once again looking for a loose connection it turns out the board i fitted in the top right hand corner there is a silver chip that controls wifi and bluetooth under the antenna there was a small black spot i noticed once carefully cleaned up i found the culprit there are 2 tiny fuses that blew conecting to the wifi chip this chip must also control bluetooth and NFC as that no longer works also.

Do you find a solution

I did find the solution unfortunately it requires the wifi ic chip to be replaced along with the fuses accompanied to the chip on the logic board but that means micro soldering the new chip on the other solution is change the board out when you take the antenna at the top off at the top right is the silver chip look at the circuitry and you should find a black burnt out spot also check the aerial for plastic burn where the chip sits
Thats the only solution available that ive found, not even the factory binary found the issue with the hardware though
That one chip though controls the wifi/bluetooth/android hostspot/NFC funnily enough though even though its blown visually the wifi toggles on still and will every now and then pick a network up for a second, the bluetooth toggles on but will not find any other device and other devices cannot find it either, the android hotspot turns on and broadcasts a signal but when trying to connect to it it will not connect, the NFC toggle is also set to on with the writing and toggle greyed out and NFC apps asking to turn on the chip but it cannot be toggled these are symptoms of the error,
If you would like to inspect your device,
If you dont know what your doing order a new backing i can successfully remove them without cracking them with a hair dryer, screen puller the cheap ****ty ring ones, and a guitar pick,
To start heat the backing of the phone up with hair dryer until its warm/hot next step is my secret trick to pop the watertight seal take the sim tray out and no **** blow into it youll hear the seal break get the ring puller pull it up enough to get the guitar pick in and just slide it all the way round,
Once the backs off theres 3 screws at top on antenna your gonna wanna use a phillips #00 for them once the screws are out get a pair of tweezers and slide them into the slot on the left side of the antenna where the vibrator is and pull up it will probably go flying if you use to much force but it wont break, the circuit and wifi module are now exposed on the top right diagnose the board for burnt spots if there is there, take the NFC chip off below the antenna and then the speaker to expose the charging port check the bottom right hand corner for circuitry burning also.

Hi, I have same problem for long, I tried all software options: factory reset, network reset, hard reset, wipe, firmware upgrade, downgrade,,
I can use NFC without problem but WiFI and Bluetooth are greyed out or stucking on turn on without finding anything.
Could you confirm what is the right IC for it ? I found two different IC number one on Ebay another on Part4reparirs , not sure which one is legit as both claim to be G930 wifi-IC (can't add link as I am new user)
also I would be interested to know where to buy fuse for it
I really miss my phone for few month using spare xiaomi now

Hey mate im a phone technician,
Ive got a few boards qnd broken S7 laying around ill pull one down and take a picture and label it and what not & will post it here for you,
The ic chip isn't actually a fuse its an actual chip which controls the wifi and bluetooth functions of the phone NFC is locted on 2 different part of the board aswell as wireless charging coil etc, so if that stuffed best of getting a new board, but however there is a small thermistor (ThermalTransistor) just before the wifi bluetooth ic hopefully for you its blown that and stopped current before getting to the wifi ic, i will also label this in the diagram
Hopefully in your case its the thermistor youll know anyway if it is will be blown with black or white residue everywhere and your antenna may be partially burnt out in that case, you will also need to check the daughter board for black or white burn residues also in the bottom right hand corner ill take a picture and label again also,
If i cant get the pics up straight away for you its because xda app is being a pain in the ass still and wont let me upload being playing up for a week now

Thanks for reply,, based on your explanation still other thing like antenna fuse thermistor could be damaged and ordering them one by one + shipping is not good idea.. I may better find cheap broken LCD S7 and ask technician to swap the board for me.
