GPS lag ?

Hello all,
I have noticed a small GPS lag on the Iolite (using Igo8 or Tomtom7). basically, the position shown on the phone is 50m behind the actual position when driving at normal speed.
Did you notice the same thing ?
Cheers,
koa

It´s normal, not a iolite-problem, on other devices too (I has an HTC Artemis with the same effect). In other forums like "gpspassion" the problem is knowen and fixed. Must use google, U will find some solutions.

Do you have a link? I searched gpspassion but could only find a thread about reading about this problem on xda-dev. Too much recursivity for me.

Oh thanks, I thought there was a specific fix, but I will try these tips and see.

Is this problem solved? I wanna by Iolite, and don't want to have any problems with GPS.
BTW, is there any comparison between Iolite's gpsone module and sirfstar 3?

I'm also curious if these tips solved the problems.
My experience is that if I take a turn from the highway, my TomTom lost me for quit some time. It shows a map where I go halfway straight on and after some time it shows a "diagonal road". Looks like a drunk seaman.
After closing TT and restarting it's allright.
I think it's also time for a good firmware upgrade anyhow.

X1 - GPS does not work anymore

Hi all,
since today all of my gps-programs (smartrunner, terracrosser, on the road panel) i´m normally using (at last yesterday) do not find a gps-siganl anymore.
I´ve tried htc gps-tool, but it is saying "failed to send NMEA command"
In settings the internal gps is set to com4, harware (external) no com, managed by windows.
Any ideas, or is there a program to check if the gps-chip is generally ok?
Thanks and all the best.

Coincidentally, about 5 days ago I found that my GPS on my R1A ROM stopped functioning after exactly 2 minutes. Tomtom and all other GPS apps would get a fix normally, then crash the phone after 2 mins (Tomtom goes gray) and a soft-reset is needed to get the phone going again. I tried reinstalling most of the apps, but nothing seemed to help.
In the end, I took the gutsy way out, flashed my X1 to R3A (even though there's rumours that it's not the 'official' release), and everything has been good ever since.
I know it's not really a 'solution', but I sure as hell couldn't find the fix. I've had my Xperia since the November release with R1A, and it just did this to me about a week ago.
Anyways, happy with R3A having skipped R2A. Not HUGE benefits to upgrading, but definitely some positives.

Hi Scar,
flashing to R3A means that all programs and data will be deleted?
Isn´t there a way to reinstall the gps-driver, like at "big windows"?
How did you flashed? With SE Update Service?
I am a X1 User for about 7 weeks, so i do not had such issues until now and flashing would be my first time.
Any other ideas around?
Thanks and all the best

Hi mrx_bln,
Flashing to R3A will mean that your device data will be lost. If you use ActiveSync, then all of your Contacts/Appts/Tasks/etc. will get re-synced when you re-create the partnership after flashing. You also might want to search the forums for "PIM Backup" which will allow you to set a "Custom" backup to grab your files, as well as its ability to save Call Logs + SMS.
I flashed my ROM by using the microSD method, which is to place the (official) ROM in the root of the Storage Card, and have it named "kovsimg.nbh". You'll find more info from Jack Leung in the ROMs section of the Xperia X1 forum here.
As far as I know, there is no way to reinstall the GPS driver. If you have never got a signal though, and your symptoms aren't like mine were (I got a fix for 2 mins then it always froze after that), then you might want to leave it outside for 10 minutes to ensure that the GPS isn't working. Also, run QuickGPS to make sure you've got the latest data file.
Hopefully you can figure it out, as flashing is a bit of a pain to have to reinstall and reconfigure everything. The silver lining to that dark cloud is that you can ensure that the device is running mint.
Let us all know how you make out!

If your GPS crashes satnav apps after a couple of minutes, try deleting your 'extra.bin' file.
This is the QuickGPS download file which is likely to be the culprit, and you can always download another which is likely to be okay.

Hi all,
thanks again for your suggestions.
I´ve run "configuration - system - delete memory" (in german: Einstellungen - System - Speicher löschen) from the phone, which is a "hardreset", i guess.
And look, after that my GPS is working again.
The HTC-GPS-Tool is working and my favourite apps (Smartrunner, Terracrosser) have GPS-Signal.
So, my result is that is was definitely a sw-problem and i am wondering that there is no fix for this, because regarding to some threads it looks like that happens quite often. I mean, even the developers of htc gps tool should have the knowledge to write a fix, don´t they?
May here is a wm crack who has a look at what a hardreset is doing with the gps and writes a little tool to fix this manually?
Many other users would appreciate a lot, i guess.
Let´s have a look when the problem comes up again
Even the quickgps tool came up with an error (something like "can´t connect - try later"). Then i will try to delete the "extra.bin"
All the best

My GPS hasn't been working for about 2 weeks now. Not about to hard-reset, but would love to find a simpler solution.

Try this solution. That worked for me and many others It is way simpler than a hardreset

I have exactly the same problem after every ROM flash.
And always manage to fix it in 4 steps:
1. Erase GPS data using the HTC tool, wait 30 secs, all satellites should vanish
2. Cold start the GPS, wait 30 secs
3. Power down the phone, power back up
4. Start the HTC GPS tool again and wait approximately 2 minutes for the gps to fix. If you screwed up steps 1-3 then after starting the tool you will get a pattern of satellites. The screen must be clear and it should start looking for satellite 02 (searching for almanac)
Never had to cold start the phone- I suppose it does exactly the same as my four steps.
I was working with various GPS units before and the Diamond one is definitively the most fiddly of them all.
I suppose there is a bug in the COM4 GPS communication protocol, I have noticed that the stream of data often cannot be stopped by closing the connection with the GPS inside the tool.

Mine works again. Downloading new QuickGPS seemed to solve the problem.

i have the same problem with my gps since yesterday - could you please give the link, from where you got the quickGPS?

I thought QuickGPS came with the phone. Load up the program, then hit 'download' and soft-reset just in case.

Thx
I've tried it - so I think I have an other problem with GPS

get gps working in standby

ok so about 6 months ago i find a website, not here, it was just a small website and some guy had a fix for the standby issue for touch pro2 I did not have it then so i let it go but now i can't find it. I was hoping someone knows what im talking about. Thanks

Hello,
I think the site you are looking for is this one
http://www.madhacker.org/HTCTouchPro2.htm
Hope this helps

that is it. Thanks.
I should note that i tried this app and it does not work for tomtom but i think it works for google maps. try for your self and report back.

Thanks I will try it also with some other applications.

It works brilliantly with memory map, but not with copilot.

GPS Problems on a new G1

I'm on my third G1. The first one died to some strange graphics issue where the screen would go completely pixilated and wacky on me. I think the graphics processor was overheating. On the second one the touch screen died about the same time the speaker in started buzzing during calls.
Luckly because TMobile extends your warranty 90 days every time you get a new phone, I've only had to pay for shipping. I got the latest one, and immediately installed Cyanogen 4.2.5 on it. No problems. Then I followed Michael Mayhew's instructions for the maps update to get Navigation.
I can't get the GPS to work at all. I've since tried going back to RC29, or the base Cyanogen 4.2.5 without the maps hack. I've tried other GPS applications such as the Chartcross GPSTest. I can't get a read at all on any of them. I don't know if it was working before the updates, because I never tried to use maps before I installed the mod.
So I'm wondering somehow a radio update was applied that broke this phone, or if there is anything I can do to change the gps drivers around. Anyone with similar GPS failure issues?
I don't really want to return this one as I've only had it one day!

Yes, similar issues. No solution thus far. I also did not test GPS before flashing. OOPS?!? And now it no longer works, but I can't tell if that was the case to begin with.
I followed the same procedure (CM 4.2.5, Navigation mod), and had the same result--broken GPS. "My Location" not working, "Searching for GPS" forever, etc.
So two possibilities I can see:
1) hardware problem w/GPS
2) one or a combination of CM 4.2.5 + Nav = broken GPS
I have seen a few people on these boards say their GPS doesn't work all of a sudden. In fact, there are stock Droid owners with issues.
Can anybody chime in?

Hmmm
So for about 10 minutes on Friday it started working again. Totally random, I have no idea why. I was at a party and decided to see if it was working. All of a sudden I had signal (using GPSTest) and google maps found my location.
I've since tried it several times, rebooting, and doing a bunch of other stuff. I can't get it working again. Total fluke! So frustrating!

Well now the new version of google maps is in the market. I've successfully installed that one but still no GPS.

Im having the same issue on my G1 right now. Sorry for the Zombie thread, but did this ever get resolved?

I've had the gps fail on my phone and others I know have also. The g1 seems to have issues with the gps antenna strip breaking internally so one minute you'll have reception, the next.. nothing. Only solution is to find a new antenna strip and replace it (good luck!)

Aside from possible hardware failures, the GPS units on these phones tend to be very weak. Sometimes it *IS* impossible to get a strong enough signal to lock on, even when out in the open if there is something nearby that can reflect the GPS signals.
However note that these are AGPS devices, which means that with a cell connection and a data connection, and given that google knows the coordinates of the cell tower you are connected to, it is able to load assistance data (almanac + accurate time synchronization via NTP), and this will *GREATLY* improve your chances of getting a good lock and greatly reduce the time it takes.

I doubt that it was the GPU overheating. Your phone would burn your hand if it got that hot.
The in-call buzzing could be corrected by shifting the screen a little bit while it is happening. It is related to GSM interference with the speaker. The speaker is literally playing the radio waves emitted by the phone. The touchscreen issue was probably a broken cable... also related to moving the screen.

What radio version are you running?

I've also had no luck getting a GPS signal ever since I installed hacked navigation... I wonder if that's the problem? Has anyone tried removing the hacked navigation, to see if that solves the problem?
BTW, the problem started on CM 4.1 with EBI0 radio (2.22.19.26I), and still persists with CM 5.0.7... Has anyone tried upgrading their radio to 2.22.23.02? How about the folks that have gone back to the Updated Rogers EBI1 Radio (3.22.26.17)?

I have been having the "searching for gps" problem as long as I can remember (although I just got this phone a month or two ago)....I remember trying to install the hacked navigation or something so maybe that messed it up?...this phone was never opened, and I would hate to have to open it up to see if it is a hardware issue because I may not put it back as it was. IDK what to do, I even started a thread about it and tried every solution I could find and nothing worked for me....
I wish someone could chime in here with some insight...but it is also nice to hear others with this issue and their advice/ideas also...
Has anyone tried un-rooting and returning the phone back to complete stock and wiping everything ? has that worked for anyone?

GPS and athletic programs like Runtastic problem

Is it my device or is it a general problem? Gps of G2 locks very very fast, has signal even inside of a room, lock many more satellites than any previous phone. I dont have problem with car navigation eg navigon. So where is the problem?
I go for running. I use runtastic. Here is a photo of recording of gps:
It is very very bad. It is like it takes signal every 30 seconds or something and draw lines. . I run in the road but it shows like i run in parking , or above cars. The same applications with galaxy s2 is very accurate. I also tried many others athletic applications to see if it is some incompatibility of runtastic but, the same happens to all.
I even tried tracker booster from play store to see if it is a sleeping problem , but didnt help.
Any help on this? Anyone using G2 for running , to write his experience? Thanks.

Have you tried other apps? If it doesn't happen in other apps, it's probably this one.

I'm on my second G2 (took one back to buy at full retain), and used each for 10+ days. I use Endomondo, no issues on either phone. Not sure if you can or if even possible to try and recalibrate the gps signal. May be your gps chip, and if you can, return it.
Even having same issue using say, My Tracks?

My tracks i haven't try. I have try endomondo , same problem. Best of all work sport tracker. I just notice that even navigon have a small problem. When i stop it still goes on and again go back.. With galaxy s2 that wasnt the case. .
As i have bought from foreign eshop it is very difficult to return. . I dont have any other problem except of this but , it is important for me...
Perhaps first of all i have to do a factory reset.
If there is any way to recalibrate gps, if anyone knows... I am rooted. .

Yeah, I mean, it seems like something is wonky with your gps. Have you tried: https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2
Understandably this is important. I had similar issues with my 2year old GNexus, and it drove me crae crae. At the very most, cna try a factory reset... but I'd check the other gps I linked to see if that helps.
Good luck!
