Used Xperia XZ for 5 days and found network issue. Often very weak signal and no Internet service. Incoming calls not possible sometimes. And now, even worse, No Service, could not locate network. Replaced SIM card, issue not solved. Put the same SIM in Z2 and it works very well in the same place. Anybody got any idea? Signal strengths show the same for both Z2 and XZ at -99dbm. The XZ is now unusable and I needed to go back to my Z2.
