And given how fast i usually tend to disable tons of bloatware on touchwizz devices, the software on S4 is nothing to write home about.
Moving my neck to scroll or palms to scroll hints on some sort of severe arthritis developing in the future. Some "natural UI" that is, of course. No wonder they included the S-health app lol
Samsung invented a solution to a problem that no one was having. A solution that actually takes more time than the original. Gesturing like a demented loon to make a picture scroll is not easier than simple swiping the screen.
Whilst an argument could be made that this feature would be handy in a kitchen for example, I have to say to that NO.
If the phone was asleep / standby, you would still have to turn on the phone / unlock it / launch gallery / launch the photos you wanted to view.... Then wave your hand over it. ?? I mean really think about it. You have to press the screen / device at least 4 or 5 times before you can swipe over a photo so it just makes no sense.
Even still the fact that the gesture require an exagerated movement and there is noticeable delay between the camera recognising what you are actually doing meaning you'll often swipe again thinking it's missed what you want it to do is all just a complete mess.
If samsung wanted to protect the screen from messy hands then surely inventing a new screen protection / covering that made it water proof or extra tough and resilient to grease would have been a far better invention than air gestures.
A feature that barely works, and doesn't solve any real world problem, but when enabled causes real world issues (lag, extra memory usage, extra battery).
I give credit for Samsung trying to invent, but invention for invention sake, and one that doesn't solve the residing issue they are inventing it for - means it's all utterly moribund and redundant.
I like the S4 generally, but I wish samsung had considered user experience as a whole and pushing forward with improvements to the device that benefit all (such as maybe better speakers / better & tougher & oleophobic coated screen for example) without hurting the overall experience of the operating system is the sad truth.
Any feature that has to be turned off in order to preserve the general user experience should either not be there in the first place, or required far better integration with the system ui that it didn't affect it detrimentally.
