Samsung is the best 4g smartphone for personnel use.It’s processing is very good.It has 16 GB ROM and 2gb RAM which makes it really fast.It doesn’t hang.It has a good camera which gives you a good picture and you can also click selfies from it because it also has front camera.It’s touch is very smooth and non breakable because it is made of guerilla glass. I recommend you this smartphone because it is easy for use, it’s style and design is glamerous, it is reliable and easily available and cheap as a smartphone.So buy it because it’s is really 4g.
