Recently in Bitcoin Wallet for android (version 4.05) I've noticed that every so often my main address will randomly change where as before it would never do this. Is this a specific function of this version? Also the address used to be displayed in the top left corner of the screen and it isn't anymore. I have to click the QR code to display it.

Has anybody ran into this? Is this normal behaviour?

I know what you mean. I actually held off on the last drop and now regret it. Even though it only bounced back a little over $100 I still should've bought some when it dipped below $300. It's getting to the point where I think 'ahh it'll dip down again no rush' even though in the back of my mind i know that's not the smartest way to think.

I enjoy the swings. it makes things exciting.
