@goununo: Unfortunately the GPS fix, I was loudly happy about, did work only a few days and now sometimes, after good tapping on the back of my phone at the E-loading place. So I am still thinking and searching for a definite repair of GPS fix. It is amazing that a fine smartphone is not GPS working. I am very disapointed about Sony. When I buy a new phone it will be surely not a Sony. Also because of updating the Android OS only 1 time. Apple updates his phones much more and for longer time.
Lots of succes and let us know if someone found a repair. I will certainly.
I found out that narrowing the load contact has as result that the GPS function is working steady now. In did tapping before in that area but it was not working steady. Malfunction of a flickering loading contact and carfully repair of that contact was also the GPS solution .
