There is a bit of a learning curve going from the Galaxy 9+ to this guy. There is no home touch on the bottom, buttons are different, no indicator light in the corner anymore. It's been a few days and I'm getting used to it with no difficulties. The camera is great, the size for the basic model is the same as the 9+ save like 1/8" which is great bc I was worried it would be smaller. Overall I'm happy with it.
It works pretty much the same as my Samsung S8+. The reason I gave it 4 stars instead of 5 - it didn't come with a charging cable and it doesn't have a headphone jack. Everything else is awesome on this phone.
Hardware wise, this is a very good phone. Android is also very good but Samsung's obsession with Tizen and preferring Tizen integration over making this the best Android phone makes this less than the best choice.
