[Sony Xperia P, U, Sola, Go] rado77:
Hi all,

I'm checking things regarding speed of GPS connection on my XperiaU. I'm new in this area but as I know, GPS uses /System/etc/gps.conf file when GPS is turned on. The "problem" is that my GPS is connecting appr. 3 minutes till it catch GPS position. For example my old LG P690 is 2-3 x faster to lock GPS signal. I'm using "GPS Test" application on both phones for checking GPS signal strenght and number of found sattelites.

So now, original gps.conf in my XperiaU ICS contain this:

SUPL_HOST=supl.sonyericsson.com

SUPL_PORT=7275

That's nice but it's not telling me what's up :) I found some threads here in this forum regarding modified gps.conf files for concrete region or concrete country. But noone explained conent of these files. I downloaded one file for my country (Central Europe/Slovakia), and it contain this:

I said wooooow, this must work! But no, time to catch GPS signal is the same...appr. 3 minutes. I'm checking GPS signal allways on the same place on opened space. So what? I found other gps.conf for Slovakia:

What's uuuuuuup????!!?? Still the same fixing time :(

My opinion - this file is used only with cooperation with using network data. It's not for GPS system itself, but can be used when I turn on also mobile network - for example like using google maps.

And that's my question - is this gps.conf file mandatory for using pure GPS (without using network connection) or not?

Thank you very much guys,
