I've had the s4, s5 and each time they only got better. With the s5 I was disappointed with the fingerprint scan as it was useless but everything less was great and with the s6 I only have to place my thumb down and not slide it. For what I use and need my phone for the s6 more than meets those requirements. And I wasn't happy with the speaker being on the bottom until the first time I actually used the speaker and was like wow........I don't have to have it up full blast or lay it face down like I did with the s5.
I absolutely love this phone it does everything you need it to with ease and the app's are amazing. I would recommend it to anyone who wants a phone that is also a computer and so much more and easy to use.
I love that the screen is so big, without having a super big phone. It's easy to use, user friendly interface. The only bad thing I could say is that it doesn't take good front camera pictures in dim lighting.
