Make sure you download the firmware updates and turn off X-Realty!
Is it something I need to download manually on the computer? I checked for updates on the phone and it says I am all up to date. I also checked Sony's site and they have this listed:
Latest available software: 17.1.A.2.55
That is the version I currently have on my phone.
Also, are you using your phone on AT&T or T-Mo? I can't seem to get the LTE icon on T-Mo, only 4G, and I'm wondering if that is just because its an international phone or if I should expect to get the LTE symbol...
