Im an android user and this is my first Iphone. My work bought me a 7plus because I refused to buy one. It was nice of them to do so. So now I'm trying to figure things out on this phone. The biggest issue is that whenever i walk into a store with the magnetic security wall things they go off. I was not sure what it was so i took my phone and waved it passed the security wall things and it went off. How do i stop the phone from doing this? I know it can be done as i see many people walk threw them with iPhones and they do not go off.
