I have had fun getting to know my new phone. A few frustrations along the way, but have found my way through most of those frustrations. I went to the Samsung tutorial a few days ago which helped me along. It showed me how I might eliminate some of the pre-installed apps so as to extend the battery life, and then I discovered a few other things such as turning off Bluetooth and a couple other apps when not in use. However none of these things have done a whole lot to extend the battery life. Otherwise I am very happy with my Galaxy S 6. Easy to use; letter and numbers on the keyboard are a good size (as opposed to my Galaxy S 4 mini.) Phone is a good size and feels good in the hand. I like the double click that activates the camera, also it's much easier to load multiple images to Facebook (something I never could do with the G S 4 mini)
I love the sleek design and the quick operating system. It is smooth and easy to navigate through. I recently had a note 3 and believe that I got an upgrade that is beneficial to all my uses.
