As the title says, I'm an iPhone 4S owner who soon will become an "ex - iPhone owner". I just want to change OS 'cause I need some fresh air. Anyway, I don't know which Android phone should I choose. Obviously, the choice is between the HTC One and the Galaxy S4. I've already "deleted" the Nexus 4's choice. I'll use the phone.. well, to do "normal" things, such as web surfing, photos (I like, sometimes, to use my phone as a camera, especially when I'm abroad), social networking and stuff related to university. So.. Thank you!
