updating software
when im trying to update my software on my phone it always say that update is interrupted and i still have the current software. but when i take a look on some of my friends S4, i see that they are either running jellybean 4.3 or kitkat 4.4. im using a diffferent network carrier although my s4 was made by at&t. im not sure if the software my fone was referring to was either the at&t software on the phone or the android version software. so if its not about the android, how can i do something about it? help please. thank you
