Phones aren't my thing.  I don't know what it uses for a browser.  I don't think it's Chrome, Firefox or Opera.  It's probably some thing that is related to Chrome because it's an Android operating system.  I know I can't update the operating system.  Though I've been looking into a different operating system.  Most of the time I don't care.  However at times I go with my wife to one of the shows she does and I have a lot of free sitting time where I'd just as soon watch video's.  

Other than that I seldom use the phone.

I just really don't like it when things don't work.  No matter what they are.  A little OCD I guess.
