Samsung galaxy s5 is a great mobile.It has 2 gb ram. And most likely like other samsung devices it doesn’t hang. Camera is awesome witj lots of features rear camera is 16 mp and front camera is 2 mp. Front camera is only 2 mp but then also it’s awesome great clearity.It has super amoled display and it’s awesome. It is also waterproof so there are very less chances that the device will get dirty.Overall it is an awesome device I loved it
