What is the difference exactly? Dropped frames = lag.
I am not complaining myself. I think the S4 is awesome. I am just saying I can see why iPhone users would turn their noses up at it.
My experience is that many smart phone users don't need valid reason to turn their nose up at phones they don't own.
I'm pretty sure we're in 100% agreement except for some minor semantics. Many people think lag is the same as slower performance. So if a "non laggy" action takes 1 second then a "laggy" action would take 1.5 seconds. The "choppyness" is just a drop in frame rate. So if the action takes 1 second and it's not "choppy" you'd get say 30 frames and a "choppy" action would only get 15. It still only takes 1 second to do the action, it just doesn't look as nice. It's just that these terms aren't used the same way by everyone. I'm not saying there isn't a problem, just that the actual problem isn't always being accurately reported or interpreted becasue of this semantic confusion.
That is to be expected since it's specs are better. The fact that the N4 beat it at all, in any area, is an example of just how big an anchor Touchwiz really is, and why it is a bad thing.
My experience with Android so far is that the camera is the area with the least consistent performance. It could take my camera 1 second or 30 seconds to come up at any time and neither would surprise me. If that performance difference in the video is repeatable then it's definitely an issue, but just one instance isn't enough to convince me. Fortunately I'll be able to check it out for myself tomorrow evening.
I cannot wait to see what the Google version of the S4 looks like when relieved of the Touchwiz pollution. I fully expect the Google S4 to trounce the N4 in all areas, including UI smoothness.
My guess is that the Google S4 will force Samsung to address any choppyness issues they have. This is just speculation, though. It's obviously possible to fix but whether or not they decide to do it is definitely up in the air. I don't have a good enough feel for Samsung to have any faith in my guess on what they will or won't do.
It is something they can probably fix. But who knows if they will. Samsung will fix the stuff people complain about the most first.
It's not a Samsung issue, it's a Google Maps issue. I don't even have my S4 yet but I've been rotating instead of zooming on my Motorola Droid X2 since the day Google introduced that rotate "feature."
