The ability to 'get on' with a phone is a curious thing and very difficult to quantify or predict.
I loved my first and second Blackberries, but the screens were too small as my eyes get older, so got a Note2. It had many good things, but too many infuriating limitations, which not even rooting and modifying could address (the screen in sunlight perhaps the worst, though).
Then I went for an LG G2, which was excellent with just a few options missing, but it was a little s...l...o...w sometimes. As the battery faded I went back to a Blackberry, as Iiked the look of the Passport.
That was excellent, if a little awkward at certain times, but the camera was dreadful and the lack of available apps proved too much.
So I now have the S7E and like it a lot. It is easy to use, has all the tools I need, and lasts a long time. There's always a learning curve, but I found this one quite easy, perhaps because Samsung are limiting the bloat.
