i rang the shop earlier but i forgot to mention that my phone is playing up, i just told them that i want to swap it.. tbh i am disappointed with it. i decided to buy s4 coz i thought it's better than iphone based on what i've read from reviews.
i have set my phone to automatically connect it to our wi fi and to my surprise when i checked my data usage i was shocked to find out that i'm close of going over my allowed data. i still have to find out how did it happen coz our wi fi is on all the time.
