In my never ending quest to collect all the iPhones I'm glad when I finally get the 6S+ and 6S as I've had them before but sold them and happily rocking my SE. Honestly if there were one...maybe two phones to keep me on them for a long time it would have been my Note 5 and SE. Honestly, I may keep tabs on the Note 6 as I still love Android, but right now at this point in time, the SE is ticking all the boxes for me. If Apple goes OLED or SAMOLED soon then I may give up Android but there is no denying Samsung has some beautiful screens.
Honestly I think the SE will keep me longer than anything else I've owned. I also kept my 5 longer than any other phone I've ever had.
I have a Note 5 and the SE. I use them both. The Note 5 I've had since Nov last year, and it's been a great phone so
far. The SE I use on my days off from work, or walking, much more pocketable.
