Hello Friends I am Usman Haider. I am professional engineering and its my hobbie to make comments on any think.
I personallt use the apple iphone 4s in my profession from some angle you can say that it is good mobile if u have a work with internet because in that phone the speed of net is perfect and it never be hanged its overall speed is also good battery timiing is also perfect but the problem which I faced during its use is that First, is that you can never share any think for this phone to any other phone samsung of any other phone.You can share data from iphone to iphone only 2nd, The new apps in the play store are moslty of cost these are not free to install you have to pay to run these apps.
According to me these all are the biggest problem for a professional to use a mobile
So if you are professional then try not to purchase but if you are using it for fun or for sylte then these phone are the perfect example Because their style are awesome and touch is perect to use
