Went to play with this phone the morning it came out on Wednesday and was very disappointed. I was prepared to return my iPhone 5 and get the DNA but I didn't. The display is amazing, its a great sized phone and its lighter than I expected. However, the problem was (as it always is with Android) Sense and Android apps. I will preface this by saying this was a brand new DNA. It had only been set up for 10 minutes and the employees had only tested a few pics they took. So it wasn't like someone had abused the demo model already. Whenever I went to the camera or into any app and then hit the home button, there was a good 2 second lag. I could see the home screen but it was frozen and then would come to life a few seconds later and would work just fine. That could have been the weather animation on the home screen, but I didn't like it.
Then there were the apps. I logged into Facebook and right away my newsfeed appeared but scrolling was painfully slow, even after everything loaded up, it was just slow and lagged all over the place. Opening a photo lagged, trying to comment a pic lagged, even liking a pic lagged. Not good. Pulled my iPhone 5 out to see if it was a network issue maybe but nope, my iPhone scrolled wonderfully as usual with not a hint of lag. Same thing with the NFL Fantasy app. Lagged horribly just on the homepage. I didn't even bother going into my match ups.
Next I downloaded speedtest on the DNA and gave it a run. While it got a respectable 12Mbps down and 4Mbps up, the test on my iPhone 5 at the same time showed a 22Mbps down and 7Mbps up. Same network, same LTE, same building and same server from Speedtest. I wasn't too surprised by this as I tried a few weeks ago with the Galaxy S3, Droid Razr HD and Razr Maxx HD in the same store and my iPhone 5 was constantly 8-10Mbps faster down and a good 2-3 faster up. Granted, when I opened websites at the same time on both phones, my iPhone was only a second or two faster loading them but I expect MUCH more from a powerhouse quad core processor like the S4 Pro, it should have been faster than my iPhone but it wasn't. Pretty sad because I had high hopes for this phone, oh well.
