*Hopeless* GPS after 6.1 Update?

I know this has been touched on before, but I want to know if this is a widespread thing or what - since the official 6.1 update, my GPS has been really poor, particularly on a cold start. In fact, every time I use it feels like a cold start these days, even though Quick GPS is downloading data regularly and always shows 6+ days.
Every GPS app is the same - Tom Tom, GPS Test, Google Maps, Live Search - I can be waiting up to 10, 15, 20 minutes for a fix. The only time it's quicker is if I've used the GPS recently, and even that is a bit of a black art.
I like running the official ROM and I'm happy with the update in every other way, but the GPS problem is driving me up the wall - am I the only one? Is anyone running the proper ROM and not finding their GPS impaired?
The weird thing is, I can watch GPS test picking up two, three, four satellites but it just won't lock...
This is with the WWE 3.28 ROM with the 3.28 SPL loaded (fixing the freezes under Hard SPL v1)... what's going on?

Usually, I've found the GPS lock time is Radio Based. Maybe try a different Radio.

The only thing that is going to get me off the DEATH V3.5 ROM is a newer Rom by this same person.
The GPS is the best that I have ever had...
The phone signal is the best that I have ever had...
The GPS lock is about 30 seconds after TomTom starts...
The battery life is phenomenal - (it takes about 24 hours for the phone meter to register correctly) but I had 79 percent battery life left after using the phone all day yesterday at 11 pm last night (unplugged it at 6 AM).
Obviously - your carrier, your radio and ROM and where you are in the world can affect your signal greatly - but at this point - for me - the DEATH V3.5 ROM and radio rock and will stay on this phone as I LOVE having no phone issues.

Ok, maybe I've not been clear here - I'm not wanting to swap ROM stories or compare radios, I'm asking if anyone else is experiencing severe GPS problems with the stock ROM, and stock radio.
Anyone?
This isn't "which ROM/radio is best for GPS", it's "did the HTC ROM break your GPS?"

I have never looked at the official HTC ROM for comparison but I had the same thing after updating to certain ROM (non-official) the only way around it I found (other than replacing the phone) is another radio. Its not a problem with the ROM at all my good man just replace the radio and you should see a quicker lock time
I use radio 1.64.08.21 ang get a lock after approx 10-15 secs

Well If you are going to be snippy about it. Never mind. Forget I tried to help.
Though You may be hard pressed to find someone who is using the Stock ROM, I believe most people are wooed by the magic of Leo26, ConfusedStu, dutty, and the other Chefs out there.

So you wouldn't say that quoting my post back to me as "...snip snippity snip snip..." was being "snippy" in the first place?
I'm not trying to pick a fight here, I'm just interested in whether this is a common problem or not. I know GPS performance varies between radios, but with this new ROM & radio the difference is pretty shocking, and given that HTC are expecting the whole world to have installed it, I was surprised nobody else seemed to have noticed. You're probably right, nobody here kept it for long enough to find out apart from me, but I like my phone to be "stock". I guess this is my reward.
The answer probably is to try another radio, but it's a funny old situation.

I'm using the new (WM6.1) stock ROM from HTC on my Tytn-II and haven't had any issues with GPS lock. I would say less than 30 seconds assumming it has a clear view of a good percentage of the sky. Fix time is the same whether I use TomTom, GPS Tuner, or the HTC-GPS Tool.
Ofcourse if I try and start-up GPS while indoors or in an area where buildings block more than 50% of the sky then the fix time can be much longer.

I had the same problem after loading the 3.28 Hard-SPL. Reverted back to stock SPL and GPS is lightening fast.
Are you using the stock 3.28 SPL or the new 3.28 Hard-SPL?
Did you run Kaiser Tweak? if you did I would Hard Reset and try GPS test.

Got exactly the same problemwith the htc stock 6.1 rom. Nothin to do with hard spl etc as neve used it - phone has always been htc branded.
it appears that although quick gps data is downloaded, it is not used hence taking a long time as it needs to download the almanac data frim the satelites instead of quickgps. Ive emailed htc, but i have NEVER had a reply to any questions ive a ked in the past.

I'm on the stock SPL - my phone is Vodafone branded so I was originally using Hard SPL (with which I flashed the original stock HTC Rom) and then flashed the HTC 3.28 SPL after I found I had freezing issues with the 6.1 update. Haven't touched the new Hard 3.28, but from what you say it's obviously not going to help. I did wonder if the mystery fix in the 3.29 SPL might have something to do with the GPS, but if it's working fine for you on 3.28 who knows.

That's how it looks to me too - looking at the signal levels in GPS Test etc, it's not obviously a problem with the radio performance itself, which makes me doubt that changing the radio will actually help (while it will no doubt screw something else up).

I was just browsing through an interesting thread here - http://forum.xda-developers.com/showthread.php?t=292178 - on how Quick GPS works (or didn't work for a while) on the Artemis. There's some interesting stuff there about how all this is supposed to work.
I'm really suspecting that Quick GPS is broken in some way in the latest ROM. If it were working, then the phone should always have the almanac data and this should be visible in the settings screens in Tom Tom and other gps progs as satellites it's expecting to be there, but for me - unless I've had a very recent lock - it's always blank. In other words, the data isn't there, regardless of what Quick GPS is saying.
And a good question would be - where should the data be? Quick GPS itself is stored in the \windows folder, but there's no sign of the "packedephemeris.ee" file mentioned in the Artemis thread. Does anyone know where we should be able to find it on the Kaiser?
Another question is what server(s) should Quick GPS be downloading from - in my non-functioning Quick GPS, the settings in the registry are as follows:
HKLM\\SOFTWARE\HTC\QuickGPS\0\0\IP > xtra1.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\0\1\IP > xtra2.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\1\0\IP > xtra3.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\1\1\IP > xtra1.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\2\0\IP > xtra2.gpsonextra.net
HKLM\\SOFTWARE\HTC\QuickGPS\2\1\IP > xtra3.gpsonextra.net
The three servers (xtra1, xtra2, etc) are also listed under HKLM\\SOFTWARE\HTC\QuickGPS\SNTP as Server 1, Server 2, Server 3 - does anyone see anything different on there working model?

Im having the same problem,
Running Dutty's 6.1 Dual rom. Once the ROM had installed I noticed that QuickGPS didn't work straight off the bat. I suffered long GPS lock wait times. I found a QuickGPS cab file which fixed QuickGPS but my lock times don't seem to have improved. Via GPSTest I get 3-4 within sight straight away, but they sit on red for ages perhaps a few more satellites with appear but again they'll all sit on red. until about 15 mins passes, then finally a fix.
Im sure my GPS responded quicker than that in previous ROM's. at the moment its not really effecting me and im really not going to go through another ROM change again to test.
Im already on radio 1.64.08.21 which is supposed to be the best out there. tut.
no idea about hard spl and all that business, not really sure what y'going on about.
Would also like to find a fix for this, as i've tried a few different methods of fixing with no luck.

So it's not the radio, which ties in with my hunch that this is more to do with Quick GPS. But my Quick GPS registry settings match those I've found elsewhere, and I've found the data - it's an "xtra.bin" file in the Windows folder, which also matches reports from working installs. And I'm having no problem with the whole downloading process, that's happening in the background (through Activesync) just as it always was.
So is there something in the actual Rom (and presumably the base rom used by Dutty) which isn't picking up that data when utlising GPS?

Well I think I read a few posts on Dutty's Dual ROM thread about QuickGPS not working straight off, but its a long thread to plow through to find out. S its entirely possible there's a good reason.
Hmmm

well I proved to myself im not inherently lazy I did a bit of searching around and found this little gem of a thread
http://forum.xda-developers.com/showthread.php?t=375172
it suggested that QuickGPS has a region setting in the registry
low and behold I checked my
HKLM\Software\HTC\QuickGPS\region
and it was set to US,
I changed this to say UK, I've not tested this but I think this might make a difference. I'll let you know whenI get the chance to play around on the way home from work. I usually try and get a fix on the 15 minute walk to my bus and dont get any fix at all, If all goes fine I'll be watching myself in Igo8 on the way home. Sad.

Hmm, fingers crossed for you, I just checked and mine it's showing "GB" though. So maybe your's should be GB (although that's not working too well for me) or maybe mine's wrong, and should be UK?

well I just popped outside for a quick test and Corblimey guvenor if Im not getting a fix in about 20 seconds.
Which is excellent to say the least since i was sat under a canopy of trees at the time and its grim as normal up't'north.
Id switch yours to UK, I didnt really think to try GB, but If its not working for you right now, I'd suggest trying UK.

I changed it to UK, soft reset, tried Tom Tom, no change. I then checked the registry and it had switched back to GB, so I changed it again, closed and reopened Quick GPS and redownloaded, back to Tom Tom again and.. no change. I don't think it's going to do it for me, maybe we have two different problems here..

Diamond Gps Sucks

I am so annoyed with HTC Diamonds GPS. It just sucks and doesn't work. I had earlier updated the radio to 1.25.06 and then it didn't work. Other members over here advised to switch to 1.25.05 and yet it doesn't work. I did a hard reset too but no luck.
Map King fails to work and Google Maps keeps on saying trying to seek Satellites and yet it just shows 0.
I am truly disgusted with HTC and will never again buy their products

Funny, I have a Diamond too, and my GPS works perfectly. Actually it's the best GPS I've ever seen. Flash 1.93 ROM, then use QuickGPS to download actual GPS positions and try again.
By the way, you're not trying to run GPS inside the buildings are you? Go out into the street and try there. GPS doesn't work inside.

Kid:
Have you set manual settings in google maps?
This way:
COM4
and 4800.
Luck!

I had a flat tyre on my Mercedes the other day! I am so annoyed with Mercedes!
I will never buy Mercedes again!!

you need out your battery from your phone and put it back after one minute.

GPS works perfect on my Diamond. Much better than some car GPS devices i've seen. Dunno why yours doesnt work. Maybe you are a noob?
Doesnt work inside buildings btw..

Mine also working fine with MapKing2007 and HTC GPS Tool....
BTW I'm setting it at 57600.... is this fine? or actually does this setting matter?

I am currently running Swift Rom v5 and yes i am trying the Gps outside. Regarding the settings in Google Maps, i have kept it to automatic. QuickGps is also updated.
I will try the battery thing and will set it to manual
Thx to everyone for their input,

As the "I will never buy a HTC again" threads are coming up in decent sequence, I would dare to see a system behind it if I would be a bad mood. Backdoor marketing at a glance?
My TD GPS is the best I ever had. Sat fix with a loox N560 and Navigon MB6 - 2 minutes waiting. Same with my TD: 10 seconds waiting.
nextavenger, sometimes the prob is not in your hand resp. on the table but between the ears or behind your eyes? Just a guess though ...

I have no problem with the phone. I own two iphones too. I am enjoying my Diamond more than these iphones. When i had picked this phone, i had never intended for Gps feature but moving to a new city all together, i figured the gps can actually help me.
I went through all the previous threads complaning about the Gps lag and gps problems before starting this thread. Its not only me who is facing a problem. I did a complete research before starting a new thread. I bought maps specially for this and if the device doesn't work out of the box, its kinda sad.

it is not diamond's problem, gps is great in there !

When I bought my TD the GPS worked perfectly. Then i start flashing various roms and radios, and began experience various problems. Hard to get fix, losing signal and a huge lag.
Finally i flashed the new official rom 1.93 with radio 05 and all my problems disappear. Now it works great. It takes only seconds to get fix and the signal is rock steady, and the lag is no worse than other gps units i have before.
Try Duttys newest rom, he has integrated the radio and rom in his download. He thinks that flashing radio and rom at the same time may cure the gps problem, and i think he is right.

I flashed dutty's latest rom,did a hard reset and my gps gets a fix in a matter of seconds.

for everyone who has gps problem, follow these steps and reset gps data:
1) remove battery for five minutes
2) install gpstest 1.04 and set it to com4 at 4800 baud
3) wait for a fix in an open space (about 3-4 min.)
4) exit the program and start tomtom (set it on integrated gps) or other navigation software and here you go!!!
These steps help everyone who has gps problem after installing, removing navigation softwares and works with every gps.
I hope this will help you. Bye.

Is it working yet ?

ok so i did this thing:
Flashed my phone using Swift's recent rom i.e v5.5
Hard Reset
Setup my phone
removed the battery for 10 mins
installed GpsTest
Loaded Google Maps
and voilla! its now working. Gps is locking fast too.

this is the best gps a ever had (except the SIRF in the XTEN until it quit on me)
from day 1 my gps worked fine with the usual lag. changed radio and flashed a custom ROM (see my signature) and no more lag.
i can guess looking at all the gps threads (i think there are more threads on this subject than threads on new ROMs) that there is a problem. i just don't understand why so many ppl has it and so many don't
btw, i am using iGO8.

Never had a problem neither with my Diamond. On the 1.37 ROM with .03 radio it took my GPS between 15 - 30 seconds to get a fix after a cold start. Which I think is already quite fast. Now on the 1.93 + .05 on a cold start I'm able to have a fix in 5 seconds more or less. I'm really amazed! I loved my Diamond already, now I love it even more

Pity you can't retract the heading of your thread....
My GPS works great also. No lag, fast locks.

You might want to download "htc gps tool". In that one you can do a warm reset on the gps, and that sometimes solves a gps problem.
Just dont run "clear storage" option in the program as you then have to restart, download quick gps settings, and restart again.
Greetings.

GPS running but without any effect...

Since I bought my Diamond, last week, I haven't been able to get a single fix.
Even worse, although my GPS is detected as running by every GPS soft, there is only one sattelit bar active at a time.
(about 10 satelits are being sensed, but only one is actually sending datas to my device, every time...)
I've never expericenced such problems with my preivous triny. There were always at least 3 or more bars moving up and down at a time, and at the end I could get some fix.
- either it is a hardware problem and I got a crap GPS chipset...
- or it is a setting problem with my ROM.
By the way, in the External GPS settings screen, I have strange infos:
Port GPS: com4 which is normal, GPS Material Port: None!!
baud rate: 4800 (which I think is very low, but I heard everybody has got the same)
What's wrong with my device?

Seems to be lots of posts on this issue...a nice simple one is to flash a new radio.....if that doesn't work do a Hard Reset (to be sure!) and restore to minimum and see if it runs.....then move on from there....

I've been having a similar problem with my Raphael (it takes a million, billion years to get a lock and even then it's only 3 satellites).
I deleted the 2 GPSlog files in the Windows folder, did a soft reset, ran QuickGPS and then tried Google Maps again. I got a lock in about 10 seconds with 8 satellites.
Now, I've only been able to test it once and will have a go again tomorrow but it's easier than a radio flash or hard reset!
Harry

Thanks for the replies!
- I've been doing many hard resets these days, due to some problems with Asian Fonts. So, this is not the problem.
I may go for the radio flashing as u suggest.
By the way, I've noticed you're using the x.x.8 radio, are you satisfied with it? I read many are going back to x.x.5 cause they it has poor performances.
-The GPS log files sounds good. I've never tried this but I may give it a try.
I tried to reset the GPS logs from within the soft I was using, but it did not improve anything, looks like the GPS only receives the list of satelits, but no localisation datas at all...

I have a similar problem from time to time.A lot of data received from 10-12 satellites but a fix only after a long long time. In comparison with the Garmin Gps I have the sensitivity of the Diamond GPS receiver is good, but the algoritm is not. Diamond radio is .05
I have the same problem if i delete the log file and update with quick GPS.
It seems that the algorithm in the radio sometimes is not able to converge easily to a fix.

My tomtom was working just Excellent on my diamond, than i did a hard reset and no gps, 1 bar for over 1 hour, so reflashed the same rom again 1.93.405 still same problem, so flashed 1.93.401 and bingo it works again. after a nother hard reset 1.93 401 rom gps wont work angin, this time the 1.93 405 rom fixed it. ( all WWE roms)
no idea why this happend.. when the diamond gps works its excellent (better than most tomtom units) but thants only when it works.
as the gps feature is very importent to me, i now have a back up bluetooth gps incase inbuilt gps fails.
and with out quick gps i find its aloms impossible to get a lock.
I only hope HTC fic this issue if not this will have been my first and last HTC product.
Any tips welcomed

Hi mates,
First of all thanks for the link and the goodies, in fact I had already found some datas since many Diamond users seem to have similiar problems with their device.
I agree this is obviously a mistake of HTC to have put a defectuous part in their phone.
1) My problem even went worse yesterday after I flashed the last HK WWE ROM: my GPS wasn't even sensed by the softs!
No NMEA datas blabla...
2)
many hard reset and reflash couldn't fix the problem. I was about to give up when i found info about that HTC GPS TOOL I had never heard about.
After using it for quite a while, at least my GPS was finally sensed and 'some' datas received, though it wasn't enough to get a proper satelit bar, not to mention a fix...
3)
So now I'm back to the same point: no fix or proper reception available, although I'm already quite happy that my GPS is detected again!
3)
I got back to the same stock radio, x.x.5 but no matter which one I use, I can't see when I'm going to have a a fix with that whimsical GPS!

SOLVED!!!
I finally found a solution to wake up my sleeping (beauty) GPS.
The most helpful infos were in that post below, but I did pick other datas here and there.
http://forum.xda-developers.com/showpost.php?p=2563369&postcount=6
The funniest thing is that this problem looks like a hardware one, but in fact it's all software related. A problem of configuration, due to the A-GPS function probably.
From what I understand, if you use A-GPS (I mean if you really have access to this special service through your phone operator) everything is fine.
If you don't, then you may get into big troubles like I and many others did...
1) make sure A-GPS function is desactivated (nothing to do with the Quick GPS function)
2)
... just follow the instructions provided by the Oijkn on the link above.
3)
delete as well the file(s) GPSlogs.txt in the windows directory
4)
soft reset
5)
enjoy a very efficient GPS

GPS Patch for touch pro/touch pro 2

- admins please make this a sticky
Hi y`all
Some people like myself have very many problems with the GPS.
After hours of searching I managed to find out the cause I have here a special patch for it.
I hope you all like it.
Install Instructions:
Second download the atachement from bellow.
install it on your device then start the program.
click fix it.
press menu and then reboot thats it !
and have fun
Greats Antonius
EDIT: Added the new program
It is working HTC Touch pro/HTC Touch pro 2 (This is tested)
UPDATE NEW VERSION ADDED
- fixed performence issue`s
- fixed some registry settings
- fixed phone responding strange.

reserved for me.

What settings does this program change?
I have no GPS issues.

it will optimize some register value`s.
it is for people that has problems and people that want a quick qps fixs.

I'll give it a run and let you know if my fix times improve.

much apreaciated
p.s. moderator please make this one sticky

On first run, all settings said they were wrong, I clicked "fix it" and all settings were changed except for #4..?
I won't nbe able to test the performance until I leave work in a couple of hours, but was wondering why the one setting stayed incorrect?

The team will put it on the list of possible bugs.
we will check it as soon as possible

i just installed and ran the program and i this is what is said

Not bashing your program at all, but i honestly cant tell a difference, i still have a really hard time getting GPS to work on my touch pro

Is the .cab uninstallable? I mean, if I uninstall it, will it revert GPS settings to original? If not, can you provide a .cab for that, or tell us what to change in registry to revert settings? I'm asking because my GPS works fine, but I want to check is it even better with this patch. One more thing, can you tell me what were the exact results during tests regarding GPS lag - is this patch fixing the problem? GPS lag is inaccurate reading of the current position on the road - without the patch we usually get two seconds of lag behind the real position.

The main problem with the GPS is radio version. Registry settings make only a small difference. All radios barring the two new 1.14.xx.xx versions have an issue where if you restart the device, sometimes the GPS won't work. It will fix one or two satellites but never achieve lock, even after many minutes (this occurs only sometimes...if it works first time, try restarting the device a few times and attempting again). The 1.14 radios seem to work fine first go for me (with the exception being TomTom, which from what I've read has a known issue initializing the GPS...if you initialize it with another program first it will work fine, and on most attempts will even work fine with TomTom as the first program). While they have some other minor issues, the 1.14 radios are generally regarded as very good (personally for me .25.35 is a battery eater (uses about 10% overnight as opposed to 1-2% on .25.05) while .25.05 has issues when at very low reception where it thinks it is still connected but cannot actually manage to transfer data). I recommend anyone having issues with the GPS try either of these two radios before they bother doing anything else...
P.S. I might just add that it would seem that the GPS lag is largely software related...I'm told TomTom for iPhone (which has a very reliable GPS) also suffers from a noticable lag whereas I know their standalone devices don't. This would also explain persistent comments from people that some programs display less lag than others.

The main problem with the GPS is radio version. Registry settings make only a small difference. All radios barring the two new 1.14.xx.xx versions have an issue where if you restart the device, sometimes the GPS won't work. It will fix one or two satellites but never achieve lock, even after many minutes (this occurs only sometimes...if it works first time, try restarting the device a few times and attempting again). The 1.14 radios seem to work fine first go for me (with the exception being TomTom, which from what I've read has a known issue initializing the GPS...if you initialize it with another program first it will work fine, and on most attempts will even work fine with TomTom as the first program). While they have some other minor issues, the 1.14 radios are generally regarded as very good (personally for me .25.35 is a battery eater (uses about 10% overnight as opposed to 1-2% on .25.05) while .25.05 has issues when at very low reception where it thinks it is still connected but cannot actually manage to transfer data).

there is a special radio rom version been cooked by our team right know.
we hope that it will give it a boost to the gps system.

new version is uploaded

what exactly does this do?
What registry changes does it make?
this should be in software section, and there are already many threads out there discussing GPS issues.
if your having trouble with GPS are you using aGPS? enabling it will get u a lock in under 30 seconds.
See FF Nokia aGPS Settings in my signature.

well i now got to hard reset , my phone won't startup anymore

I did not notice an improvement, however I have not installed your fixed version.

guys,
sorry that some of you must hard reset your device.
but we fixed that in version 1.1
and fone_fanatic we dont have any problem any more with the gps.
we want to help the comunitie as a company!

With ENERGY ROM and 1.14.25.35 radio, I get GPS lock in 10-30 seconds on first use of the day and within 5-10 seconds in subsequent uses. Just note, that after hard reset or just new flash of ROM, the GPS lock may take more than 2 minutes, as it has to download all ephimeris data.

xperia X1 freeze when use GPS

Xperia X1 freeze. After 6 months I have problem with my xperia and gps. When I try to use internal GPS (whenever software), display freeze and I have to replace batery. I have tryied to flash another ROM, it works few hours and now I have same problem. Any ideas?

Hi,ok let´s see, like you ive had the same problem, just when i was using any gps navigator the phone suddendly stopped and that was sucking me a lot so after that i started to think what could be the problem, and at the end after a lot of time i found where was the problem and what was the solution. To find the solution i decided to hard reset the new rom with which all my gps problems started, and following the instalation steps of all programs and configurations i found the problem and this was related with the quick gps, before using this program to upgrade my gps location my mobile was runing tomtom and others without freezing, but after upgrade the gps location with the quick gps my mobile started to freeze. So this is the problem, just do this try to hard-reset and install eveything but dont, i repeat dont !!use the quick gps or this will freeze your phone again. Following this step your phone will run the gps navigators without the freeze problem
Then men after this try to do this and let me know (PLEAE) if your problem still remain ok? see u and hope you can solve this problem like me.

I too have just started having GPS problems as listed above!
The problem seems to be Quickgps...as soon as u run the quickgps update(which you may have on autodownload) Tomtom crashes and you have to reboot the phone...
I have reinstalled a different rom since and still have the same problem!
i dont know if there is a cache for this program that can be cleared or something other than reflashing the device
As the days go on and the 7 day update starts running out im guessing more people will start having the same problems!mine happened 28/10/09 evening time!

Same problem: freezing XPERIA when using GPS!
Yesterday I connected my X1 to the PC and got the latest Quick GPS update. Today I'll need to use my gps for a trip... Wanted to prepare the navigator and got the same problem like you guys.
Probably something wrong with the last update since I have not installed anything nor updated the firmware.
Is there any way to get any older version of the quick gps? Before after each 7 days period, it was possible still to use the GPS. Even though it was much slower but in the end it always works before updating... Will a hard reset give me an old version of Quick GPS?
This is so annoying at this moment. Hope somebody find a solution fast.

Hi all,
Got the very same problem yesterday.
I tought the GPS HW had gone. I have uninstalled the Route 66 SW, but there are some files that still lay in the phone.
Then re-install everything from scracth, but problem remains. Now i know i a GPS. Could be worse if was a HW problem in the phone.

Possible solution
Hi
I have maybe same problem with other phone (HTC Rose). If any application try to connect to GPS, phone freezes. After Hard Reset it was OK, but only until I use QuickGPS. Then it again freeze whole mobile after use GPS application.
My temporary solution:
1.
Erase QuickGPS data. Simply delete 2 files: Temp\xtra.bin and Windows\xtra.bin
2.
Soft Reset phone.
Try it, and let me know.

working so far...
Thank you motaba.
I did what you proposed and erased the files. It worked actually.
I have been running my gps now for some minutes and it did not freeze. It found the signal and started to navigate without freezing.
So at first glance it seems to work. I will try it further and tell you all about further information.
but how can the gps work so fast and well without these quickgps files? are they totally redundant?
Greetings

Thanks a lot motaba.
Works for me as well.
As yes, it got the location pretty fast without the "A GPS mambojambo"
I was gettin 8-9 statelites.
P.S: Anyone can tell me were to get TomTom 7 for X1 ? Route 66 is pretty anoying some times....

X1 GPS
After deleting the fails xtra.bin my gps start to work for now, but I want to ask do I have to use quickGPS update if I update the gps from there the problem will be start again

Yes delete xtra.bin helps!!!
Does anyone has older version of quick gps. I still want to use quick gps, becasus waiting for gps to fix is annoying. thanks

Hi all,
After deleting the xtra files and confirm that works i went out, and during the driving i used the GPS.
Even went going out of the car and switching GPS programm off, as soon as i got back into the car and switch programm on, the GPS location came so quick that was unbeleivable. Only time to switch it on , put it into the older start the car and when i look into it, was already navigating.
So my advice is FORGET about Quick GPS.
I think ESA as lunched a new GPS satellite for the European system, I wonder if has anything to do with with it. ??? Anyway it's great !!!

No, ESA satellites are not primary GPS satellites. They provide WAAS/EGNOS correction info only. AFAIK Xperia does not support correction, so it does not work with these satellites at all.
The problem could be with QuickGPS data. Many users started to have the problem at the same time. It seems xperia uses QuickGPS if they are available. So any corruption on QuickGPS side makes GPS unusable.
Sometimes just forced QuickGPS reload helps .. but sometimes not, and that's when the trick with xtra.bin comes handy.

Thank you all in this awesome forum. Deleting the xtra.bin files solved the problem for me. Even the time to log the gps position seems not really to be slower in my case

Hi Dr Sid
Thanks for the explanation.
My point was that the xtra.bin removal works, and after i did that the GPS position was found very very quickly without starting Quick GPS.
I wonder why because, before it would take 10 minutes or more, if quick GPS was not used.

Summer time change?
Hi
I was wondering what is wrong with xtra.bin. It is downloaded from web server xtra1.gpsonextra.net or simmilar.
In my country (Slovakia) at 24-25.10. there was time change from summer time CEST (GMT+2) to CET (GMT+1). Maybe it is some dependance between change of time and GPS problem.
Wiki says same time change is all over Europe.
All of you with same problem, please check registry, what servers are set in QuickGPS. My phone is HTC, so registry are there:
[HKEY_LOCAL_MACHINE\Software\HTC\QuickGPS\0\0]
"port"=dword:00000050
"IP"="xtra1.gpsonextra.net"

THANKYOU SO MUCH!!
This has been driving me crazy!! I have only just learned to put ROM's on my phone and this is when the problems started, so I suspected the ROM's was causing the problem.
Deleted the 2 files and now my GPS works perfectly.
Excellent fix, saved me so much time.

THANKS THANKS THANKS !!!!!!
Works for me too (Buenos Aires - Argentina).

It's very probable that this is the problem, since I have it since a few days also. But it's strange, last time change I had no problems with it.

hehe, a bit slow to find this thread
yep the quickgps data is corrupt somehow.
took me a lot of reboots to find this out.
A-GPS still works just try running google maps with GPS turned OFF!! you get a rough idea of where your are.
QuickGPS gives a weeks calcutions of predicted GPS satalite locations which can then be used to reduce the cold-boot gps startup time.
If you live near the coast at all, your GPS chip will also pickup the land based stations that broadcast static information which helps in the accuacy of location.
It is quite possible to live without QuickGPS, it just makes the startup time anything upto 2 minutes.
However, with quickgps being used for so many phones, it should not be too long before its all fixed again

It's just pity it can't be disabled by some normal means. If you delete the file, QuickGPS will load it back next week.
Also it could try to compare data from the file with data from the satellite. If different satellites are visible than those which should be visible based on the file, than GPS could realize something is wrong. It does not.
