Note 4 is the best android phone ive ever had for sure. Insane battery, awesome screen that i can see in the bright ass sun , amazing camera and the pen seals the deal for me, very responsive and very useful.
The only bad side is that it is not submergible like some other phones, so its ok to use in light drizzle rain but you sadly, cant go swimming with it. Another negative I've found is if I use the note as a flashlight, the size is kinda inconvenient in certain situations lol. So i started carrying an actual tiny flashlight with me on my keychain and it works much better
I think the best part is I can use it heavily and never have to worry about the battery. 6-7hrs of screen on time is the normal for me. Also for 20/30$ you can add wireless charging to it and with fast charging I can get 50% battery in a 30 min charge which is insane considering the battery is pretty big.
Overall I went in expecting to hate the size but it grows on you pretty quickly and I highly recommend it.
