Downgrade to Kit Kat 4.4.2 and you will be happy again.
Firmware 18.3.C.0.40 is bug free, tested for 4 days: autorotation is working fine, no other problems occured.
You will have a phone, not a lollipop piece of crap.
I've found a fix, but as usual one needs to have root. In the file /etc/gps.conf it's just a matter of changing the value of
A_GLONASS_POS_PROTOCOL_SELECT = 0x2
to
A_GLONASS_POS_PROTOCOL_SELECT = 0x4
I did some tests today with more parameters and I could narrow it down to that single one. Don't ask me what it really does, I just know that in KK 4.4.4 it was set to "0" instead. Anyway, this is a Lollipop fault, issues with GPS have been present since 5.0:

PS: actually I am not sure anymore. It did work for few hours but today it's back again working for few seconds and then resetting.
thanks Michelasso
this is a fight sony and I want to hear from someone from the developers working on it
haloo sony developers or Rickard
thanks
The funny thing is that I restored the stock gps.conf file and now it's working as a charm again. But I do delete at boot the files in
/data/misc/location/gpsone_d/ with the command
rm /data/misc/location/gpsone_d/*
in a /etc/init.d script. Not sure it matters, though. It just seems random. Maybe it depends on the satellites position and the ugly weather in here in the last 2 days.
I use everyday navigation
and now I have degraded phone, sony really thank you for your answers
I'm sorry to hear this 
I will forward this internally and let you know as soon as i have more information.
One more.
Hello.
I had android 4.4.4.
I used Waze and WiFi access points without any problems. (everyday)
I did the update to android 5.
Now the gps goes crazy (I tried with several Waze Software, Maps etc)
The location is intermittent. Therefore impossible to use a GPS software (very painful because I use it for work).
I reset the device (factory mode) and install waze, I have the same problem.
I install "GPS Status & Toolbox" I feel this helps a little.
We can see satellites, but the position does not.
Using waze long operation stabilizes. But every reboot of waze, gps goes crazy.
My phone is original I do not want the rooter.
Besides sharing connection wifi access point no longer works.
Sony helps us.
