Ok, I have let the phone upgrade the Android System as it has been moaning at me to do and I have to say there has been no improvement in the GPS performance. It is very irritating that sometimes it works, other times it does not. It sometimes starts hunting for GPS signal when it has been working fine. This is in the middle of a field with clear blue sky above. And at the same time, my old HTC or Blackberry will signal lock almost instantly to twice as many satellites as this phone and stay locked on them. The location accuracy of this SONY is reporting as 8 to 9 metres and the HTC less than 3 metres. I give up and will have to send the phone back yet again - that is the 3rd of 4th time for basically the same problem. Additionally, I tried to use Google Maps / navigation for the first time having done the android upgrade and it won't work at all, just goes to a black screen.

Hello All, I have and continue to have very poor GPS performance from this Xperia U phone. The phone has been in for "repair" three times already in just over 12 months with various problems. It would go into and endless SONY / XPERIA / reboot cycle when you turned it on and the only way to get out of it was a complete re-install. It did this several times beforeI gave up and sent it away. The GPS performance was very poor throughout and the last time I sent it off GMAIL and several other apps just kept abnormally terminating - even if I did a complete re-install. I have had the phone back for a month and the GPS is still terrible. Compared to my old Blackberry or HTC wildfire it takes a very long time to get a fix and then it does not seem to get a fix on as many satellites. A-GPS etc does not seem to be a factor in this. I am going to upgrade to Android 4 but I have previously done this when getting my phone back and it has not improved anything.
