[Xperia Arc General] maRRRco89:
As suggested by a guy I add here an important request.

I hope the moderators don't delete this post, it is very important.

I don't joke, i will make a DONATION to a developer that will find a solution

for a gps bug that affects most of the stock Xperia 2011 phones, but not all.

The bug is simple, i explain it better then possible:

i turn on the Gps, wait for a fix, and start to navigate, after 5 minutes the signal drops for about 30 seconds, then works for other 5 minutes and again drops, other 5 minutes and drops, and again again again

every 5 minutes the gps drops without exceptions

:eek::eek::eek::eek:

now the datas collected in months of this problem:

1) this happens with traffic data OFF, background data OFF, absolutely no contact to the network at all, and offline app like Sygic, Navigon, Copilot etc

2) this not happen with Maps, also in offline mode, with a little portion of map downloaded before, and no data traffic

3) this not happen with Data enabled or Wifi enabled

4)

this also not happen in Flight mode

, and perhaps it is the most important information, so is not an hardware problem.

5) with the build 3.0.1.A.145 this didn't happen with data disabled but i don't want to downgrade

Here a log of the bug by a user with the same problem.

I have ready also a video, but wait an official reply from Sony, until to start to share it.

What do we think about? :

for an unknown reason Sony firmware attempts to collect data every 5 minutes, also if the phone have data disabled

. If don't find data, there is a drop out !!

Basically A-gps work always, even if data are disabled (i have no data traffic, my sim is disabled for internet connection), and this must not happen, because it causes a drop, its attempt is not silent for who have data OFF.

So, please, say me you can do something, you are best developers then Sony ones.

And please, i don't want see post like: "I don't have this issue", this bug can be releted to country, or particular situations that are present in a phone and not in an other, but most of the 2011 range have it.

This discussion is only for tecnichal informations.

If you need something else, let me know, i will add all the infos.

A donate wait to who will fix the bug definitively !!!

First P.S. for who is interesting to help me, but I see perhaps this bug is too difficult for you and noone can help me,

I tried different gps.conf file, trying to delete all the command lines releted to internet, like Xtra or NTP server

now my gps.conf file is so:

# DEBUG LEVELS: 0 - none, 1 - Error, 2 - Warning, 3 -Info

# 4 - Debug, 5 - Verbose

DEBUG_LEVEL = 3

# Intermediate position report, 1=enable, 0=disable

INTERMEDIATE_POS=0

# Accuracy threshold for intermediate positions

# less accurate positions are ignored, 0 for passing all positions

# ACCURACY_THRES=5000

also this setting doesn't work.

But now i know something more: the gps try to collect xtra data from internet until it receives all effemeridi informations.

It continues to drop every 5 minutes because it searches first these infos from internet, but if doesn't find a connection drops and then collect the infos again from the sky, until next 5 minutes. If in this time receive the xtra data from sky, it doesn't drop more, but if not a new attempt connection with data disabled of course, results in a new drop out.

This repeat every 5 minutes until the gps receive the effemeridi informations, this can happen for 20-30 minutes or more.

So it meas 5-6 disconnections every 5 minutes.

The absurd thig is that if I start in flight mode i get a fix in 10 second and can use gps for one hour without issue.

So this means gps really doesn't need these xtra files from internet !!!!! But Sony continue to believe so.
