It's day 25 with the Samsung Galaxy S 4, and it's crunch time. In this update, I'll recap some of the things I've learned, some of the things I love, and some of the things I find frustrating. 25 days into the challenge, and I'm certainly conflicted, just like many of you are. There's clearly a battle underway between the Galaxy S 4 and HTC One, and there are things I love about both. On the pros list, I really appreciate the Galaxy S 4's 5-inch display. It's not too big, but big enough that it gives me the ability to browse YouTube without switching to a tablet or laptop. I'm still frustrated with the slight lag that the Galaxy S 4 exhibits from time to time. I shouldn't be seeing that on a device with a quad-core Snapdragon 600 CPU. Some will blame TouchWiz - I love the benefits that the UX provides, I just hope to see it get a bit smoother as time goes on.
