A:AnswerHi.
This stylus works for any cellphone or tablet with a capacitive touch screen. Like most cellphones in the market.

A:AnswerYes, but the same way your finger would work, do not expect the "Pen" performance, since the stylus is only a capacitive surface that mimics the your finger tip, no other function.
A:AnswerIt'll be a 1 year manufacturer's warranty, which is standard. Most Best Buy stores can handle Insignia warranties in store -- as it is the Best Buy generic brand, if you would. Be sure you have your receipt handy and they should be able to exchange it or provide a store credit. Keep in mind, this warranty won't cover any accidental damage and the like.
