I've read your old post on 'incognito browsing', and I thought I'd tell you something interesting.
I'm using that mode on my Samsung 3 from time to time.
Today I handed my phone to someone to look at a baby photo and they accidentally held down the menu button on the bottom left (next to the 'home' key) - up pops a generic search screen with ALL my incognito previous searches in plain view.
I was able to go in later and manually delete them.
I tested both incognito and regular search to see what happened.
ONLY incognito searches showed on this generic search page!
So incognito is not as incognito as they say!
Please feel free to check this for yourself and pass on to others.
