[Q] Weak GPS signal, long satellite search [SOLVED] - HTC Desire S

Problem solved. Fix: http://forum.xda-developers.com/showpost.php?p=25128818&postcount=15
-----
It is as the title says. Actually I am a huge fan of Endomondo app and running, skating activities, that's why this feature is very important for me.
I have a Desire S on MIUI 2.3.16 rom, flashed radios aswell. Usually it takes approximately 50 seconds to find satellites, sometimes it can't even find anything at all. It's so annoying! Had no problems on stock HTC rom.
So far I have tried this fix, but results are the same: http://forum.xda-developers.com/showthread.php?t=1493695
Any exits?

Try this thread instead - as it is for the Desire S;--

Okay, I have tried this method.
First of all I started to managing how to replace that gps.conf (located in /system/etc) from custom one to original, but it does not allow me to copy & paste there. Nevermind...
Then I installed zip from sdcard via Clockwork Recovery. Switched off my Desire S and removed battery for 1 min, just by time, then assebled it back and switched on. Turned GPS on and entered for ex. Endomondo app, yes it really showed "GPS o.k" after 2 seconds of sattelite search!! Before it was those 50+ seconds. Well, I was happy and sure that everything went fine and now I have superfast GPS responce. But not so fast! I did a trip for few km's and the app counted no kilometers at all! Then I entered Google MAPS app and GPS could not be able to show my position. But at the same time GPS icon on notification bar was not blinking anymore saying that device is searching GPS sattelites. Why so?
Are my GPS settings ok? (my location is Europe, Latvia)
NTP server adress:
us.poo.ntp.org
SUPL server adress:
supl.google.com
SUPL server port:

/HTC Desire S, MIUI rom 2.3.16

try the free application FASTER FIX that assisted me.

Faster Fix works for some people, but all it does is changes the one line in the gps.conf file to reflect the local NTP server for your region. My understanding is that makes very little difference in most situations, but some people certainly do gain from it.
The AGPS fix has seemed to be much better - it actually tunes the whole GPS setup. I used the "Google Specific No-SSL v3.1 build" and it made a massive difference to my GPS system. I also installed "GPS Status & Toolbox" from the market and use that to reset my AGPS data and then download AGPS data as well. This seems to need doing from time to time (I do it every day) just to keep it fully in sync.
Like most fixes, different people experience different results - but looking at the thread and the information that way seems to be the most reliable.
Also, if you use any form of AGPS fix then make sure you uninstall Faster Fix as it will attempt to overwrite the changes if you run it.

I also recommend Fasterfix download it via Market.

Hello gentlemans,
Looks like my HTC Desire S GPS has totally stopped working! Nothing helps, even flashing from MIUI or Cyanogenmod to Reaper etc. I have a feeling it might be a hardware problem, because I have faulty dropped it, not hard, but still. Does DS have GPS module flex cable? If yes, it might be loosen, if it really is there. Any ideas?

I think i have read somewhere on forum that GPS antenna is in top back plastic cover of DS (where the camera and flash are). It's connected via sliders like WiFi antenna on battery cover. If you dropped your pet "head first" it maybe loosen the contact...
Don't know if this helps you, but i wrote it anyways
Hope you fix it! Good luck!

Did you wipe everything before flashing? I had same problem with internet access with different ROMs until I made full wipe and now all works fine.

Search the older posts. I wrote once: the problem might be HW. Your GPS antenna contacts might be bad. If no SW fixes help you - look it up.

I have disassemble my phone. But maybe somebody could say me corectlly where GPS module/antena is located in HTC Desire S?

GUYS!!
I have just noticed that GPS signal improves a lot when I take back cover off. It even connects to satellite while with cover phone sees 2 satellites max and does not connects after multiple tryings.

Finally, GPS works great! I simple applied 2 layers of double side tape on contact to isolate it from back cover. Now everything works fine. Few months of managing and works great, I didn't notice such changes before.
Another contact stays for signal receiving.

Hey, that's a neat trick man... how'd you figure out which is the GPS antenna and which on is the mobile one? Kinda counter-intuitive right, that disconnecting the GPS antenna gets you a better satellite lock! HTC would be hiding their faces if they found out, LoL!!!

That's like that, thanks.
I used a wire to make connection by step with first and then with second contact. Then I noticed that by touching one of them mobile signal improves. Applying wire on GPS signal contact give almost no improvement. And it means that I should lock the unnecessary contact by method I described below.
I hope this somehow helps for similiar experience users.

Hey dude, I had exactly the very same GPS problem with my Desire S. The GPS antenna is right below the camera lens and definitely not where the battery lid is. Anyway, I used the tape stuff and it works. For the first time I have a stable GPS fix after few seconds, even without data connection, meaning pure GPS and not A-GPS. However, there is no way I can explain this. THIS IS INSANE!

They probably would be surprised a lot! It's hard to explain, but seems like there is some kind of interacting between transmitter and cover. And contacts there are not made just for look.

So all you have to do, is make sure that one pin can't make contact?
But why did they put it there?
That is very strange!

GPS Locking

Hi all, is it only me having difficulty locking on GPS? I tried stock, leaked gb, bionix and eagleblood but no lock. It shows 5 or more available sats but it won't lock.
Any help is appreciated.
Sent from my Gingerbread powered Nokia 3210.
No, definitely not just you. There's something definitely off about the GPS driver in this phone. If you use an app like GPS Status or GPS Test, you'll see that the signal-to-noise ratios are all lots higher than they should be; whether that has a direct effect on TTFF (time to first fix), I don't know, but it's certainly indicative that the interface isn't right. It's also clear that it's not using the AGPS the way it's supposed to; it should load the ephemeris data and give essentially a hot fix (<15 seconds) every time, but I only get a warm fix (75-120 seconds) if it's been long enough for the ephemeris data from the satellites to have expired (~4 hours) since the last time I used the GPS. It also happens that occasionally I won't get a fix at all, but generally rebooting allows it to get a fix quickly.
I don't know whether it will help or not, but you could try fiddling with some of the GPS system parameters via the hidden menu (dial 1809#*999# and find "GPS Test").
I'm hoping that this is one of the things that will be fixes when we get the Gingerbread/bug-fix update, but I don't have any basis for that hope.

Other than stock, which would lock super fast for me, I have had the best results with the Ultimate rom. The first lock took about 2-3 minutes but since then it has been fairly quick. Could just be dumb luck though lol.

You need to copy hiddenmenu.apk and two others to /system/app! It's there in one of the GPS fix threads on Development section! Search for it!

Was talking about the FC when dialing 1809#*999#! That should be fixed once you put the apks in /system/app! From there you can run hiddenmenu -> GPS Test -> Start button and see if that brings up your GPS icon!

This may sound crazy, but download and give "GPS AIDS" (I know dumb name) from the market.
That app (even the free version of it) has helped every phone that I've ever had GPS issues with. The comments for that app speak for itself too.
Give it a try before buying to make sure that it is compatible with your phone first. Best of luck...

The setup always fails for me. The two files it needs to download don't download; the light is red for both and it says the file failed. I'm running CM7 so maybe that's the problem, but it just is not working at all.

Bad / Useless GPS reception on HTC Desire S

Bad / useless GPS reception.
Sorry for the long first post but I have been here for a while reading and absorbing all the information on here. I wonder if anyone can help me here.
Basically my GPS reception is rubbish. Lots and lots of people with this phone say it is great so it must be something wrong with my phone, either the hardware or some setting in the software.
I have posted some questions on another forum but I still cant understand what is wrong so I thought I would post on here as there seem to be a great wealth of knowledgeable people on here. Please feel free to tell me to look somewhere else if you know of some answers and I will apologise now for wasting your time.
Should I be looking at installing a different Rom, mine is the factory default, if so which one may make it better does anyone know.
Thank you very much for any help.
Keith.
----------
Here is some of the previous transcript which should explain the problem:
More of a rant really than a question, but I have come to the conclusion that the GPS on my phone is useless. When I first got the phone (feb 11) it seemed to work ok. I could use gps quite happily for navigation apps, but now it is rubbish. I put another thread on here a while ago saying that it could ‘see’ satellites but would not lock and give a position. Now it only occasionally sees any. Can the reception degrade over time? I am using it out doors with a perfectly clear sky, wifi on, data on, and have tried putting the phone down in case holding it impairs the signal but it is just rubbish. I loaded an app recently called GPS test (this is android btw) and this shows the signal strength of each satellite. When it eventually sees some or any, the strength is always in the low (orange SNR10) range again with clear sky etc. I recon when it does occasionally get a signal in the yellow (20 SNR) that’s when it locks on and gives a fix but I cant prove this as it does it so rarely these days. I am guessing there is something faulty with the phone or GPS receiver. Anyone know if this reception can be improved in any way? Eg. standing on your head with a finger in you ear. Anyone else have this phone and find the same as me, or is it just mine? My Nokia that I had before was great and would lock on straight away, is the HTC just rubbish?
----------
On quite a few HTC phones the config file is set to USA ... the file is a text file named gps.conf and resides in \system\etc folder
it can easily be replaced if you phone lets you have access to that folder, or a 'fix' can be re-flashed if your phone is rooted.
the correct settings for UK are as below, and if you want a working gps.conf file, or the flash, PM me and I can supply them.
if you can 'see' and edit your current file, and it is not as follows, then edit it as shown.

I hope have fixed it. It is working great now. . . . . for the moment.
I tried lots of things, rooting the phone so I could modify the gps config file, followed all the suggestions about recalibrating it, installed FasterFix. Nothing. In fact it got so bad that it just wouldnt work at all. My next step was going to be to install a different rom to see if that made it better. I had one already to go, but first it says to perform a full factory reset. so I did this. mmmm I thought, I wonder if that makes the gps work... and sure enough this is what seemed to fix it. It now locks on with in 10 secs and is perfect, just as it was when new. I didn't bother with the rom just carried on with the original one after the reset.
So if you have a similar problem, I can recommend you do the same - perform a full factory reset.
Remember you will loose everything you have installed and all your contacts so make sure you back these up first. I then went through reinstalling all my apps and GPS is still working well. Something must have go in there to stop it working but I havent found what it was yet. Fingers crossed it keeps on working.
----------
Solution found! I had a HTC desire and sold it coz it had this issue. I got myself an s2 and same issue.I spent a couple of hours messing with kernel and stuff to no avail anyway the solution I found is: Download any giffgaff apn app from market and delete all old apns than add and delete giffgaff apn a couple of times and presto gps suddenly works fine with about a 30second time until first lock followed by about 3seconds overtime after that God knows what the apn has to do with gps but it works!
I hope this helps others with similar issues!
----------
Do you know I think you are on to it here. Well it defo works again at the moment after doing as you suggest.
I downloaded the app called giffgaffAPN. Deleted and re added it a few times. At first, it didnt seem to be any better but I then reset the phone and ta-da instant (ish) lock on. It has been ok since the weekend so looking good. I wonder how long it will go this time before it stops working. When it does Ill do the above again. Hopefully this is the fix. But like you I wonder why the APN settings affect it. Strange.
----------
This fix above defo worked for me to start with but now it wont. I was out the other day and needed the GPS so did the above procedure but it wouldn't work. I tried it what must have been a dozen times, deleting, restoring and resetting the phone, but nothing. It just sits there and maybe after 10 minutes it will see a couple of satellites but after 1 hour I gave up waiting for it to fix position. It is infuriating. Why is mine so bad when others say it is no problem on theirs? Time for another factory reset to see if that fixes it. Trouble is I loose all my downloaded apps which is a real pain. Anyone know how to fix this?
http://forum.xda-developers.com/showthread.php?t=1442032
Worked on every rom i tried.
All hail crypted!
Tried that AGPS patch quite early on. Made no difference to mine.
I am going to do a factory reset again to see if it works after that.
Next I might try a new ROM. Which one is best for GPS reception? Do they differ at all?
Thanks.
for me, I dont need to use any gps patch or manual edit. I dont know why, my gps is working so good. Better than iPhone 3GS. lol.
maybe my radio version? i dont know @@.

Incredible isn’t it. Why is mine so bad then. It is so bad I would probably never buy a HTC phone again because of this. I am assuming it is the phone. I must have some faulty hardware I guess. The wife is after a new phone and I won’t be getting one of these or even going Android. Will have to spend the extra and go with apple even though I personally don’t really like these either.
Im not really sure about this, whether it's hardware problem or what. Maybe you should try flash everything, from hboot, radio, to rom. Make it variance. Maybe you can get a good gps locking somehow? :good:

[Q] GPS won't lock

All,
Hope you can help. I've been happily using my Desire S with GPS for a couple of years now, mostly on Reaper 3.0 this year and 4.0 since I came out, but also on other ROMs (Endy, Fallout, JellyTime). However at some point in the last few weeks (maybe while test flashing some recent CM10 builds) I no longer get a GPS lock. If I fire up GPS Test or Maps or whatever, the GPS icon keeps flashing, and I've left it for 20 mins at times. Occasionally I'll see some satellites in GPStest, so I know that my reciever works, but I never get a lock.
There are quite a few comments about this scattered across other threads and for other devices, so I've tried quite a few things..
- Used faster fix to set my NTP server to UK.
- Used GPS test to clear and download agps.
- Used Reaper Settings to apply AGPS fix.
- Restored stock gps.conf to the standard - seems to be the same across most ROMs,
- Then used GPS Test to reload aGPS again.
- then retried all of the above in different combinations.
- Flashed CM10 (both nk111 and Flinny), same behaviour.
At one point last week using GPS Test on Reaper 4.0 the icon stopped flashing and I apparently got a lock, but the accuracy was about 4000ft and didn't improve.
I know for other devices you can clear a partition to 'cold start' your GPS. Does such a process exist for the Desire S?
I'm wondering if I've got something cached on my SD card that's persistent across ROM flashes and is screwing my GPS. I've tried using Cachemate to clear everything I felt safe doing, but that didn't help either.
I guess I could format my SD card, but that sounds pretty scary to me and a lot of effort to restore all the stuff I've got on there. Especially as I don't really know if it would help.
Any suggestions?
Matt
It might be a case of bad antenna contact. HW, not SW. When something persists after factory reset - that's probably the case.

Is that something I can get my local phone repair shop to look at - ie check connectors are seated etc? Or it is a fairly terminal resoldering type issue? Do you know?
Matt
Out of interest, My phone hes been running GPS Test on Reaper 4.0 now for the last 20 mins. It's seen 6 satellites at best all at a SNR of around 15-20, but still flashing the GPS icon and not locking.
Matt
6 satellites are very few.
It might be as simple as connectors issue.
The GPS antenna is on the top plastic, near the LED.

I did look into that. I believe that's the same AGPS patch that Reaper Settings will apply, but I did try it independantly. It's just an updated /system/etc/gps.conf as far as I can tell. Didn't make any difference for me though.
Matt
So, I prised off the camera cover to reveal the Wifi and GPS antennas. Scuffed the contacts a bit with my thumbnail and lifted the spring contacts slightly to increase the contact pressure.
Popped the cover back on, replaced the battery, turned the phone back on, and voila! Loads of GPS reception. Loads of satellites. Very fast lock.
Pretty simple process too.
Thanks for your advice everyone.

[Q] Sensation XE GPS Problem

Hello
I have some trouble with the GPS of my sensation xe. I can activate it from settings and gps icon appears but it cannot detect my location. I have tried applications like GPS Fix but could not find a solution. Simply, there is no data coming to the phone. I have tried with cloudless open area for about 2 hours and still the same.
I am using ViperS 1.4.1 mod but the situation existed before I flashed the rom.
Another point is, I had some problems with this phone and flashed some radio firmware while solving that problem so maybe it is related to the radio component. However, I have no problem with AM radio or sim cards.
Now, I have no idea about what to do. I would appreciate if you could help.
Thanks.

If the issue is GPS not locking, you could try clearing the AGPS using "GPS Test" application from playstore (In the app, Settings -> Clear AGPS) and then reboot.

Thanks for your reply.
I have tried GPS Test application. It shows both "In View" and "In Use" as 0 so I think it cannot detect any satellites.
When I click "Clear AGPS", a toast shows up saying "Clear AGPS request made".
Nothing has changed after reboot.
Is there anything I should look at?

GPS not working well

Anybody seem to be having problems with their XZ Premium GPS not working as they should be? Mine is intermittent, sometimes when it works, it works well. But the moment I took a wrong turn and quickly fired up my Google Map navigator, it have problems detecting where I'm at. The Map will show the route, but my location is all over the place. It would pause and stay in that spot for a while, then move me on a lake or off road. I tried "GPS status" app to pin point where I'm at. It doesn't always want to work.
It's getting really annoying, I want it to be reliable when I need it. Lucky I still have my Z3 as backup. So far, seems like the Z3 is the best Sony ever made.
Same problem here...It is hard to start GPS....it shows current position, it lose it. I have to fight for 10 minutes until its stable.
the same issue here. OK after reboot, but problem is back again a after
I had that problem once while downtown... the buildings in that area are all old and packed pretty closely together. It just did not want to update for the life of me. Rebooting it did not seem to help it at all. Especially using the walking directions... forget it. I didn't have time to fuss with a gps app to see if I just wasn't getting any sat connections, but if it happens again I will.
Wow, so it's a known common problem. I hope it's software related so it can be fix by updates. Now I have to open two programs to make sure it always working all the time. Run "GPS Status" app and then open Google Map. Cumbersome.
Dial *#*#7378423#*#*, service test, GPS, Purge Assistance Data
This worked for me!
My use of Purge Assistance Data seemed to help, but I've had a couple of episodes of the problem since then where it didn't help. However, in the past three days the problem has not appeared. I cannot determine what has changed; many apps have updated as usual, and in order to try to determine if this is a hardware problem I ran phone in Safe mode during which problem did not appear. Interestingly (or not) the problem has not occurred during subsequently use of the phone in normal mode. BTW, I'm running the July 1st security update (45.0.A.7.90); the August 1st version has not been offered to me yet by the Software Update).

Very nice. Seem to be working very well. Although I have not put it to full use yet since I'm working at home today. Let's see how it run when I go to work in the office tomorrow.
This won't help? - - https://forum.xda-developers.com/showthread.php?p=73337848
My XZ premium is 4 weeks old and had problems with the GPS since day one. The GPS was very unreliable taking me in the wrong direction and sometimes delays in giving instructions until after passing my turns. Using google Maps and high accuracy settings. Contacted Sony today and they have asked me to contact google first to make sure there is no software issues from their side before they can look at it. Meanwhile I will download a different navigation app and see if the same problem happens.
I did GPS location test but it seems everytime I attempt it the phone seems to take forever in finding anything so I give up normally after 10 mins.
If any one has found a solution to this problem please let me know (other than changing the phone of course)
My GPS problems went away with 45.0.A.7.120
You're not alone!! I always end up going wrong directions. Compass is very way off.

+1 here. it's really frustrating as i use my GPS a lot.
I have the same issue. Second time I sent my phone to Sony. I will update the forum.
Was having this issue as well. Purned GPS Assistance data seemed to help. also did the battery trick. maybe sony should give us an update that will not allow gps to "turn off" when using apps that require it.
i searched on my phone some where on the hidden settings. The Destination was 30mins and about 20miles or so. Said the gps was only on for around 10. Cellular data was used too. This has to be a software issue. why it shuts off gps at times.
Is Galileo enabled as Sony's promise?

What is Galileo? never heard of this. Is it a GPS feature or improvement? Such a fancy name.

Galileo is a new GPS system developed by the EU, like GLONASS is the russian GPS and Beidou the chinese GPS.
And to answer the question, yes, our phone supports Galileo.

Yes, XZP supports Galileo. But it has not been enabled yet. :/
Had the same problem, gps not locking until I purged assistance data and rebooted the device, then it worked fine for about 48 hours until I had to repeat the process.
I completely solved this problem by uninstalling Google play services updates. This was a known issue for other phones some years ago.
Can anyone else confirm this solution?
