If you turn off XTRA, you'll notice that it may require even more than 15-30 minutes to get a fix. Turning on XTRA will shorten this to almost instant fixes...

Many people prefer to disable Enhanced GPS Settings, XTRA data download. This is because 3G/GPRS data connections can cost a lot, especially if you are abroad and roaming.

It seems like Samsung has left some settings turned on in the registy, for debugging purposes, and this makes really slow to get a fix without XTRA data. According to Microsoft's documentation (see GPS Intermediate Driver General Registry Settings) some features like logging can be enabled for debugging, in GPS Intermediate Driver's registry settings, which stays between the hardware and your navigation software.

My experience shows that the following steps seem to improve the time to get a GPS fix, without need to download XTRA data:

1. Go to Settings > System > Enhanced GPS and set both settings to "Disable"

2. Go to your device's registry, and see the key HKEY_LOCAL_MACHINE\System\CurrentControlSet\GPS Intermediate Driver

3. Change the following string values to nothing (don't delete them, just edit them and clear the value):

CurrentLogFile (originally \GPSID_log.txt)

OldLogFile (originally \GPSID_log.bak)

4. Soft-reset your device

5. With File Explorer, go to My Device, and delete the two GPSID_log files you see, and the file named xtra. If you don't soft-reset, you will not be able to delete some of them.

6. Check again the registry setting. Sometimes in rare cases it may revert the settings back - but that's a general WM problem.

After this, if you start your navigation software under clear sky, you can get a fix in a coulpe of minutes, without the use of XTRA, or any other data source, than pure native GPS satellites.

To digg in the registry there are many free and shareware tools available, I can recommend Total Commander CE, which has a registry plugin.

Also noticed (but this may be really subjective) that flipping the device with the back upwards, while waiting for GPS fix, improves reception a bit - it seems like the internal receiver antenna is oriented to the back of the device... but if anyohe has dissassembled the Omnia can confirm or infirm this.

Guide Me Please!!!

I have done up to step 4 and thanks to all.

But I cann't explore and find the two GPSID_log files and the xtra file in My Device!! For your further hand please?

Thanks,

J

Why not just turn IsEnabled to 0 ?

I tried this trick (the one posted) and it didn't change noticeably :lol:

Too bad.. It's still hit & miss..

Because that would only clear the checkbox in Settings > External GPS, which may cause things not to work.

Your TomTom6 needs a third party software to receive the gps sigals and then let it to be used by TomTom6 or other gps navigations. Here I have written down how did I configure it to work in my samsung Omnia after all efforts.

2.5- Click on > button(sign). Now your samsung omnia will search for a valid gps port. and will present you with a pop up menu telling that it finds a COM4 ... do you want to use it. Click on OK button.You will be presented with Select OUT PUT page.

2.6-Choose Share with NMEA applications from OUT PUT list.( if not already selected).

2.7-Click the > button (sign). You will be presented with pop up info page.

2.8-Click on ok button on the popup info page.

Thanks. This works great. I was not impressed by the GPS before. I don't know what this tweak did but I'm getting a good fix indoors now as well which was impossible before. My ROM JVHH1.

You need a registry editor, like the one included in Resco Explorer. I think that TotalCommander (free) can also be used for that.

Weird how it is only helping some people out. One thing I have noticed is that after a soft reset before this tweak I would have to fuss around and do the 'xtra' download etc, then it would take 3-4 minutes to get a fix, but now after a soft reset the unit shows no satellites, then 15 seconds later it shows a minimum of 6 satellites, then within another 10 secs it has a fix.

My Omnia is installed with a small file called q-gps. I have tried the method described here but it didn't make much difference to my Omnia, which still takes about 5 mins to log on. My HTC TC faired much better, logs on in less than 10 secs without having to do any adjustment. Sigh....
