Whole last year I have expirienced differend display glitches with home and minimize button and sliding top menu but it did fix itself after some automatic updates or phone restore. This time the phone became completly unuseful, all my bottom buttons have stopped working at once and restore won't help anymore. I don't want to wait another 3-4 month to get them fix it. From all my previous experience I believe it is a software issue. Sony just do it again and again and doesn't learn any lessons out of it. The updates should be well tested before they release it. I'm going to switch to cyanogenmod and see if it does help. There are more then 30 pages of complaints here from different users about the same issue but looks like Sony sadly copmpletly ignores it.
