As a longtime Samsung buyer, (Samsung Droid Charge, Galaxy S3 then S4) I don't understand where they're headed. I still believe the Galaxy S3 and the S4 are some of the best phones every made. But the S6 was a no-go for me. No removable battery, no memory card, the high cost of 64 and 128 gig versions, and a glass back??? I don't want an iPhone......I like Samsungs. (or at least what they used to be).
So, I really liked the Note4, almost bought one about a month ago, but didn't want to end up with 'last year's model'. In the mean time I didn't like what I was hearing about the Note5, got tired of waiting and upgraded from my Galaxy S4 to the LG G4. I know its not a direct competitor to the S4, but for me the 5.5 inch screen, 3 gigs ram, a killer price from Bestbuy and free accessories from LG was bait enough. So I made the switch. I do have a slight guilty feeling for leaving Samsung after so many years but I'm really enjoying the G4. Especially the QuickCircle window case. So, for me, I think I made the right decision. Not sure how all this is going to play out for Samsung, but there're big boys, so.......
Good luck with your choices.
And all of these new phones are so incredible, I really don't think you can make a bad choice!
