What about iOS doesn’t just work for you?
Well for me, the ability of IOS to work as a production tool at work is limited. The file and data sharing on IOS is archaic. On Android (Samsung) i can use my phone as a mobile PC, uploading and downloading data at will to my Phone direct from my PC using drag and drop. I can take photo's or use PDF's, mark them up, save them, email them, transfer them , etc without any work arounds or fiddling. I can use the multi window which is very handy. I use NFC as well which well, IOS can't help me with. My work phone gets lots of emails on my work account. Android notifications is fantastic here. I don't have to be swiping my life away as i would on IOS. I also use widgets as well to help me, something IOS can't do
For my partner, her Iphone doesn't seem to like doing a lot of things. It is normal for her to ask me to take photo's, video's etc because her 16GB Iphone 6 is always full. My 32 GB S6 isn't as it is very easy to clean up memory on android. In other things (maps for example) she can't get it to work. This is a phone fault and a reset would fix it, but she doesn't want to reset and she can't figure out the settings in the mess of IOS to figure which bit is turned off or on.
IOS 11 has turned it into a slow buggy mess as well. App closures are common(er) than on IOS 10.
