Coming from using Nexus devices and windows phones in the past 1.5 years......
Love the camera on my Icon.....but Win10 is a possible issue, though it ran well in the last few insider builds it has issues with using a Band which are not present running 8.1.
Nexus 6.......scored it last December new for $248........killer deal and this phone is almost perfect for me...........but needs to be 5.5 and have a better camera to be my daily D.
Enter the LG G4 a month ago for $299 new ( + $23 for extra 2nd year warranty).........first time I allowed myself to buy a carrier specific phone besides the Icon....(Icon had little bloat issues and what was there was easily removed from being any issue). At first I was upset because the UI got hampered or neutered on the G4 got as soon as it was activated on Vzn network....ewww debloater time (taking out the ability to use the free FM radio really ticked me off!).....then mess with launchers that I never had to deal with before.....found a few good ones....but Nova did everything I needed and more.
Now after using the phone for some time......I do long for my Nexus clean interface and use. But the phone is so capable for me and my needs, wants, desires. Now I am addicted to the power and volume buttons on the back, and tap to wake... those is just pure excellent for me. The camera is like a dessert for an android phone. Size is perfect and with the huge screen ratio......cant ask for more especially with the ergonomics of handling this phone even with my ballistic jewel case. Made it so easy to one hand and huge protection as well.
The Nexus 5x was the only other phone I looked for....but it is a little too mid-line for me. If it had 3mb ram....maybe not an issue at all. Nexus 6P is cool and very nice.....just dont want anything over 5.5 now. I find 5 to 5.5 is doable for me.
Im pretty happy with the G4 and it just took time to adjust to with its UI and messing with launchers. I still have the N6 and Icon as backup and will use the Icon often for a camera when Im out fishing all the time. N6 I just cant bare to part with because it is such a smooth and excellent Nexus device (even though I also have a 2013 N7).
So if you do not need the clean swift un-feathered Nexus experience, the LG G4 is one heck of a phone now with the discounted prices you can get one for. I would never elect to go touch wiz or iOS ever.....ever ever. haaaa
I was waiting out the releases from late 2015 and early 2016..........The G5 sort of let me down as far as not being a upgraded variant of the G4, but something of a new animal all together. Not to say that's bad....just is not something I would feel is a vertical upgrade on the whole.
With same size phone almost and smaller screen.....1st neg.
Moved the volume button(s) off the back......2nd neg.
Seemingly not any better camera.....3 neg. (verdict still out on that for now seems).
COST compared to the discounted phones released months and months ago.
