Samsung's newest flagship smartphone, the Galaxy S5, goes on sale this Friday in the United States on every major wireless carrier.
The S5 comes packed with a new upgraded camera, a fingerprint scanner and a heart rate scanner, among other features. But do these additions warrant scrapping your old phone and adopting the S5? To help you decide whether it's the right decision for you, we are hosting a live Hangout on Air today at 1:30 p.m. ET on the Mashable Google+ page.
Join Mashable's Lance Ulanoff, Christina Warren and Pete Pachal to answer all your Galaxy S5 questions.
Drop your questions in the comments below or tweet them using the hashtag #MashTalk, and we'll try to answer them during the Hangout.
