Is Samsung 4 a smart phone?

The Samsung Galaxy S4 is an Android smartphone produced by Samsung Electronics as the fourth smartphone of the Samsung Galaxy S series and was first shown publicly on March 14, 2013, at Samsung Mobile Unpacked in New York City.

How long does a Galaxy S4 last?

It’s a small capacity upgrade from the S3, and a welcome one. Samsung claims 17 hours of talk time, and this slightly lofty goal rings near enough true with a full day’s substantial use of web browsing, gaming, email checking and more leaving enough reserves to satisfy a bit of video playback on the evening commute.
