The S4 is a great phone for its generation . Excellent screen and camera quality.
Unfortunately The phone developed charging issues within 3 months.
Fortunately the warranty was intact and I got the charging socket replaced. Would have given it a five if nor for the socket.
The battery generally drains quick if you are constantly on whats app or online, plus I guess the screen takes a lot of power too , but hey its a great screen with vibrant colours and viewing angles.The camera beats many of the latest phones in the market now.
