I just got 4.2.2 today. Can anybody tell me what this little circle on the bottom of the lock screen is? Thank you in advance!
I don't think it does anything, really, other than potentially (1) signify the home button, or (2) signify the home lock screen?
...
people were saying that chrome was replacing the browser. But I Stoll have the native browser. Any idea about that? Thanks
If you long-press the little circle you'll see a "slide menu" that allows you to launch Google Now (perhaps they will add other options in the future?). This is redundant if you use the slide unlocker, but if you securely lock your phone this allows you to quickly launch Google Now from the lock screen (though you still have to unlock).
[edit: As Malachy mentions below, the slide unlocker no longer launches camera or Now -- I hadn't noticed that]
