The title says it all really. I've currently got a iPad mini 4 and had a iphone 4 and 5 before moving over to the galaxy S5 and later S6 edge and current S7. I've enjoyed the android experience so far but I would like to flick between OS's every now and then just to keep things from getting boring. I'm currently getting the urge to go back to iOS and in particular a iPhone 7 plus. I know there are pros and cons with each OS/Phone but I'm curious to know how things have changed since I left and the thoughts of anyone else who's done the same move. I have a few questions that I can think of and would be grateful if anyone could help answer them. 1) leaving android would mean leaving the file saving ability on my phone, I.e. being able to save pdf docs from emails directly onto my device. What would be the alternative on iOS? 2) I have a large amount of WhatsApp conversations that I would like to keep if possible. How easily are these transferred over to iOS? Anyone else able to share their experiences?
