Lumia 1520 :: Bing Search Keeps Popping Up And Freezing Phone

My 1520 now has the Bing search menu keep popping up. It has dine this now many many times and often freezes the phone on that display. I have had it do this without even touching the screen. Just reading an article and out if nowhere it pops up. The only way to resume is to turn the screen off and back on. Its getting annoying and only seemed to do this after the last update, not windows 8.1, just the last regular update. I also get the screen shaking up and down sometimes and have to turn the screen off then back on. The screen contents will start shaking violently up and down. I have done the soft reboot several times and gone into the Bing settings to turn off but it still does this. I should have never updated this phone. It worked brilliantly before it. What's next, hard reboot?
