I no longer have the glitches, lagging, freezing Android came with. I do miss and the only thing I miss is how much easier it was to download music. THATS all . Other than that, I don't miss it at all. Slow to get updates and then would have to factory reset to improve the battery life.
Battery not lasting all day. Android works for many people and I had it for many years and always Samsung. I got a sour taste in my mouth with how my switching out of the Note 7 transpired and decided it was just time for a change. I had been playing with the iphone 7+ when it was released . After waiting for the 64 gig Note 5 for two months and being told it was cancelled, I decided to make the switch. This has been mentioned before. I have been using 7 months now and still liking it.
So if there were to be a big change, it would be to make music easier to download . Less complicated on Android and I will admit to that. I still have my Samsung tablet and have music on it. So still have that option. I just wish the iphone was that simple on music.
