I upgraded. Got 350 for my S6 Active the day I put it up for sale. Paid 550 new in box last June.
The Active is not my daily driver, but a niche device I usually use on the weekends etc. I plan to use it daily for 2 weeks to put it through it's paces during the return period.
I planned to hold out and did not expect to pick up the S7 active so soon until i sold my s6 active so quickly and then stopped by my local store and walked out with a gray S7 active in minutes. Lol!
Any of the upgrades alone is not enough to upgrade but if you want all three or four of the bigs ones, it is worth it to me.
Fingerprint scanner is excellent, especially if you use Samsung Pay a lot or use Chase and or BoA apps you can sign in with fingerprint.
Micro SD Card- is big for me since I take a lot of pictures and video of my kids. The 200 GB sd card has me pretty stoked!
Battery- never had an issue and even more beastly! Hearing of 7 and 8 hours of sceen on time!
Marshmallow- I know the S6 Active will get it, but the ability to control individual app permissions is big to me and I wanted it. Att is too darn slow with that update.
IR blaster- never used it and actually disabled the peel app because I thought it caused more issues than it was worth.
And the S7 Active does not have an IR blaster.
The S6 Active is a solid phone and device! I liked the colors better for the S6 active but went with the titanium gray S7 Active. Of course for those of you that are more patient than me, you will be able to pick up and S7 Active once you decide for a lot less $$$ than I did!
I tried to act like it was not a new phone to my wife but she busted me and I am still in the dog house! Lol!
