I upgraded from an S3 so, yeah, big improvement. It came Thursday and Sprint's website must have been over powered because it wouldn't let me swap. But I was able to do it using the phone itself.
- Daaang, what screen clarity! I don't want to put a screen protector on it, afraid it will cloud or tint it!
- Battery life has been good. But I use Juice Defender to help with that.
- I have a Note 10.1 (N8013) tablet so am used to the pen. I think the pen on the Note 4 is more responsive, if that's the right word.
- I didn't like the idea of the missing menu button and was already hating it when several of my fave apps were not working because of this. But I researched and found I can long press that "recent apps" button and it does the old menu button behavior. Yay!
- "Wi-Fi calling" aka VOIP. Great for us since we live in the boonies and signals here at our house is difficult/impossible. Now friends can accidentally call me on the cell phone and I don't have to say "call the house number".
- A lot of useless (to me) bloatware that I cannot uninstall. I expected that as that stuff comes with everything now. I just made a folder in the app drawer and called it "Useless". Done.
- I hadn't thought about it until others mentioned it in this thread but yeah, the voice recording/recognition is much better. I use Dragon and I got her to send a text correctly the first time, to the correct person, on the first try.
Oh, and for someone who mentioned the wireless charging? I saw on the Samsung website that there's a replacement back cover you can get and a charging pad.
