What is this Google Settings app that installed itself on my phone? Today, all of a sudden I saw this app in my Samsung Galaxy Y mobile phone:


I am talking about the app named "Google Settings"

I uninstalled it immediately only to find it installed again a few hours later.

My mobile phone is rooted and I did have access to internet through the phone during this period?

Can anyone tell me as to what is going on? Should I worry? What should I do?
The Google settings app is being put their either by the Maps app, Search app, or the Google+ app.  

It's a unified settings/sign-in thing they just added in literally yesterday and allows you to manage the settings for all of the above (and probably more in future) from one menu.
