Galaxy quattro is the phine I’m using currently.It’s performance is very good. And I have been using it for 3 years and my experience so awesome with this phone.Overall the handset is very good but the thing which we have to notice is it’s battery and front camera. The battery life of this handset is not so good overall we can say it average. I have changed it recently and this battery issue I had been facing this for past 2 years. And the second issue is it’s front camera, front camera of this phone is very bad and many times it shows very blur pictures. So, in my point of view it’s camera and battery should be made some good and if these issues get solved then it would be so competitive device in compare of it’s competitive device of same price.
