If you want to do more customization then setting a background and some widgets on the homescreen dont switch to iPhones. The App Library is a mess compared to the App Drawer Samsung has. I switched my work phone to apple recently and my frustration started with setting up the keyboard the way i used to on android. Im currently experiencing software issues like freezes and crashes to a point where my phone feels like its running a nightly build of some obscure android rom. If you are in any way keen on customizing any part of your phone, dont switch to iphone.
