GPS Problem (well researched)

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 !!!

Bloody crap gps.

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.

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)

[q] jiayu g4 gps

Hi everyone pretty new to the Chinese phones and apologies if this has been done before (i cant find it) but i have a JIAYU G4 youth which is running the latest custom rom off needrom.com (JY-G4 Yabe V7.0.2) this is the 3rd rom i have flashed and each one the GPS is very slow or does not work at all and you can not get a fix. The only way i can get it to pick up satalites is to use the engineer mode on mobille uncle tools which is quite long winded.
Ok so to my question "can the gps be improved by some sort of configuration?" I notice in the root of the sd card is a gps config file does this need altering somehow when used in UK?. Any help would be much appreciated as other than this it is a great phone.

The problem is rather the antenna in the back of the device when the device screen up and metallic body, the blocked antenna. GPS works well when the device display down.
But there are some guides on how to improve GPS software (according to me do not work):

http://www.youtube.com/watch?v=ZnY_425NgB0

This is more than only a hardware (antenna) problem. I've noticed that when I connect an external BT mouse that the mouse itselfs gets a "spot on" fix, but the phone is struggling to keep this fix.
By editing the build.prop and disable JIT the phone has a much better GPS fix.

GPS fix issue in Jiayu G4
Finally the issue is solved by 100%
The problem is rather the antenna in the back of the device .
The PCB has contacts for GPS antenna , the 1st & 3rd are the ground & the middle i.e 2nd is the main antenna.
I just skipped 1 & 3 contact by putting insulating tape between contact & the antenna.
Only 2nd point is touching the antenna .
just that's all.
Now my phone fixes GPS with in a minute in cold start.
I tried with most of the available ROM.
Pls note : If you are not a technical person do not open.
refer to some mobile repair person .
soon release the photos of the same.

Hi Pankaj459,
I tried the software fixes, which got me a quicker fix. Unfortunately the fix is not very accurate.
Very often the GPS loses its way and I find myself about 100yards beside the road or in a nearby street.
I opened up my G4A and noticed that the 3rd pole had already been isolated with black tape. I did also isolate the left pole. Nevertheless, did not see any difference.
The fix took just as long/ short. Accuracy was just as dismal.
Is there anything else I can do? Would it actually help if I modded some copper wire to the GPS contacts, or would that not solve the issue?
Thanks in advance for your help.

So do you think the solution has to do with putting aluminium paper in the antenna? I have seen that fix in THL and it seems to fix the accuracy, maybe it is the solution.
Would anybody share a little tutorial on how to do it?

[ FEITENG H9500 ] Known issues and fixes

Ok.. i see many people on this forum asking questions about this device.. the truth is this device is designed very poorly and it even may arive at your hands defective / with some or with a lots of problems.. you can proceed by your very own responsibility. Take a look in the picture for pcb details
- to Fix about every problem you need to findout how to unscrew the back plastic case and be able to see its PCB (Printent circuit Board) - Its pretty easy, just remove the little screws and give a presure at the clips of the cover to be removed, don't use metal objects because you will scratch the plastic.
* WIFI / GPS very low signal
Let me begin with one problem that you have FOR SURE.. is the low wifi signal and gps.. this is due to a horible design of the antenna.. the antenna is not just horrible, but it is also causing a short circuit it self! which is the main reason why the signal is low. First you have to stop the short circuit from happning
How to fix it? Unscrew the back cover, at the top of the back cover under the flash you will see a white sticker, this is the antenna, you have to remove completely this white sticker because it can't be useful by any way. Remove every piece of it including the copper-yellow color from the inside (the place that makes the connection.
Now find a UTP cable and take a piece of a hard copper of it, remove the plastic and keep the copper wire clear, cut it and place it in the whole were previewsly was the white sticker.. you have to place it in this way so it can connect with the inside conntact with the back plastic is placed and screwed again on the phone.. there are 2 pins in that place.. the old antenna used both of this pins (that was causing short circuit) you have to use the left pin and leave the right pin completely empty.. so the right pin doesn't connect anywere, and the left pin is connected to your piece of copper wire.
Cut the copper at the same size of the top of your phone.. so you can place it horizontal ... but you can also try vertical, (use wifi analyze app from play store to see what fits better for you)
Now.. this is the same antenna for gps.. you have nothing else to do.. just install GPS Test app and go outside and test your gps..
This is what i did and im pretty happy with it, instead i used 2 pices of copper and i covered the whole top place of my phone under the camera.. but that doesn't mean is the most right way because when we dealing with antennas there are a lot of math / and calculations that have to be done to design a perfect antenna.
the wire gives really a great signal.. just in case you want to reach the extreme.. Instead of copper wire you can use thin-Copper paper. (don't use foil of aluminium is not good) and design a better antenna copying the design of an antenna from another phone (that you know it works)
* Camera autofocus doesn't work - Or camera doesn't work at all
[Don't unscrew] Frist thing you should try is remove the back cover and give a presure in the right side of your camera with your finger.. this is the place the connector is located.. and it may gets unclipped and loose the connection after a small drop or something. After that Reboot the phone.
[unscrew back] If this presure on the right doesn't fix it, then you have to unscrew the phone.. take off the camera and give it some small hits and punches.. place back the camera and see if it works.. this is due the autofocus motor got stuck.
* Mic, Speaker, USB doesn't work
[Don't unscrew] This is due the connector of the bottom part got lost its connection. remove the back cover and give presure under the place of the SIM cards, were it writes 'WCDM' and 'GSP'. press a bit those spots. reboot, if not fixed:
[unscrew back] The two bottom connectors is 1. for the touchscreen and 2 for the bottom parts.. you need to check both of those because i am not sure which is which.
* SIM1, SIM2, Microsd not working
[Don't unscrew] Try to give some press next to vol+ / vol- buttons
[unscrew back] On the top left of the PCB there are located 2 connectors, 1 is for the front camera, and 2 is for the SIM/SD parts.. the last connector to the side of vol buttons is the connector you have to check and press to make sure is connected ok.
* Touchscreen doesn't work
[Don't unscrew] Give presure right under the headphones jack
[unscrew back] This is were it is located.

Charging Problem
I would like to add the problem with charging the batteries.
I got a new H9500, with two batteries. When i try to charge it with the adapter that came with it, the phone shows the charging animation, but it never actually charges the phone.
I have the same behaviour on both batteries.
After searching for a solution i found these:
-The charger supplied is 5V, 0.5A. Some people used a 1A charger and got to the point that it actually started to charge
-ROM problem, by changing the ROM some people were able to fix the problem, since the software was not getting correct info out of the battery's third pin.
Well none of the above worked for me. I hope someone comes up with an altarnate solution.

my expirience
Hello guys...
My story. Bought this phone for my son for 160 €. We found out that camera focus didn't work, so I took it apart.
The easiest way to take down plastic cover, after it was unscrewed, is to put something plastic under it in the place between both SIM cards places, and work around inner battery square.
When cover was off, I found out that camera plug (right of camera) wasn't even plugged in. It only laid on connector. Plugged it in, and shake camera a little and auto focus came alive.
After that I noticed that black cable between gsm antenna and PCB was very loose, so I had to sort this out
At the end I found out that speaker connections are very delicate and had to take plastic down again to properly connect speaker.
Now it is obvious to me, why these Chinese phones are so cheap. We have saying in our country: pay little, get little
But now everything is cool and my son is happy.... And I am happy

Hi.
I just got a Feiteng H9500. The problem is that the camera is not working and the camera application hangs then stop responding then quit. When I start the camera nothing apears on display. I've put some pressure then some hits and it started to work a while. The focus worked as well but It seems to me not to work excellent so I gave it more hits, then the camera stopped working again. I have disassembly it, i moved a bit the camera and removed and put back the connector and it came alive again for a while, but just the front camera. Then stopped again. I have noticed that the camera doesn't move up and down when I press on it, it is stopped down, if I lift it with a needle it goes up, so it's not stucked.I can't even comute between cameras because the aplication hangs then quit. ( Everything else works.
any help? Thanks.

Hi Guys,

My phone is Feiteng H9500 (HTM).
Appearance is similar FEITENG h9500, but not identical.
I'm not sure that have the same Rom, so I did not dare to flash a custom ROM.
View here:

I cannot read Spanish or whatever it may be
There is a ROM at needrom called something like this "feiteng / htm h9500".
That sounds like the device is the same...

You should order it by the store you got the picture of it. actually there are many stores selling parts for this phone.. almost like its branded.. unlike with other chinese phones you get a struggle to find parts, so you shouldn't face any problem to order a part.

Sound when touch on Lock Screen
hi, guys
I have FEITENG (HTM) H9500 almost a year and I am very pleased with it.
I want to change the sound of the screen when touch lockscreen, but I do not know how.
It did not sound when unlock the screen, it is the sound when you put your finger on the screen while the screen is locked.
In The system/media/ui is not, and I do not know where I'd be looking elsewhere.

No Data connection
I have had a Feiteng H9500+ for a while but recently rooted it and tried some different ROMs as well as applying a GPS fix. Somehow now my AT&T data connection is not working. The SIM settings have the data on and set to AT&T and I turned roaming on just to be sure but nothing I do can get the AT&T data to work. When I am connected to Wi-Fi it works fine. This is the only way I can get Internet.
Can anyone help me get my mobile data working again?

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.

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.
still looking forward to the pics... my Insta Gram acc is [at]kian.moments :fingers-crossed:
