I love my HTC Thunderbolt, but this is becoming really annoying. In many apps, while holding my phone firmly while in landscape mode, the display suddenly jumps to a screen titled, "Recent Apps" --which shows eight icons of my most recently used apps against a black background.
To get back to what I was doing, I have to either press the back button or the icon for the app I was using. It feels almost as if pressure on the frame is causing it. Sometimes, I can make it happen repeatedly, but other times I cant make it happen at all. It happens in multiple apps including messaging and Alchemy. It only happens while in an app and in landscape mode.
I do not know of any button or command that opens this Recent Apps screen or how to disable it.
