I know it's overwhelming at first, but just give it a chance. So I guess at first it's hard and yes I know I really miss Icloud but I'm keeping my iPhone so it's not like it's gone forever. I moved most of my contacts, email, calender, notes and music to google services so I'm pretty set there.
I love the screen size and camera as well as the design. It's thin, light and easy to use I love where the power button is on the side for me personally It's much easier to hit. But just play with it more and don't fill it with crap just bc u wanna customize it, just put things u know u want. Browse the play store and find a few things u may wanna download just don't go crazy haha
This is very good advice.
I would delete everything you don't want from the screens, then add things as you want them. Play and get used to it for a week and then add a Launcher (Nova Prime) and start with a blank canvas adding what you want bit by bit.
