Hi, I just installed the new update yesterday and lost my nav buttons at the bottom of the screen. I try to select them and nothing happens or worse, it selects the phone and starts dialing the last called number. I did a factory reset including wiping my SD card which seemed to work last night but today, I am back to no nav buttons. I have tried the factory reset several times but I don't know what is wrong. Phone was working fine prior to this update. Lots of time wasted trying to fix this thing. Help.
