This phone is much better than the S3 that I replaced. It's even a bit larger. Also newer and faster. The booting time is even better. Apps load much faster. A very good phone.
I've used other phones in the past and I love my S5. It's ease of use from browsing to the functionality of apps from third parties is incredible. I love the fact that my phone can interact with other devices such as televisions and appliances. Samsung, you have a great product here!
