Maybe you can explain it to me but I don't understand why people feel the need to upgrade their phones so often, when their current phone is barely a year old (GS4 released in April 2013). I can maybe understand when ones phone gets 2 or 3 years old and its age starts showing, but even when looking at a GS3 its still current, almost nothing sets the GS4 apart from it, at least nothing of significance. I am on a contract, which sees me upgrade every 2 years but at no additional cost, so unless the same is happening for you, you either have large sums of money burning a hole in your wallet or its a status thing, who has the bigger phone. Android is largely an inefficient OS, hence the lag on the kind of hardware that the GS4 boasts, granted it gets better with every revision, but none the less still has significant bloat, not including all of Google's spyware services. Ironically, the same has been said about windows and I find it funny that a Linux derivative finds itself in a similar situation, but that's just me. I wager the GS5 will have much the same issue, but I still have no idea why people line up in droves, exactly like the Apple fanatics, to claim a device that is at most only slightly faster, maybe slightly larger / thinner, with a screen resolution that the human eye cant discern at that size anyway. Oh and lets not forget the huge amount of gimmicks that is usually thrown in that is cool for all of 6 seconds before it is turned off because it doesn't work well enough, to cumbersome to actually use and adds zero value but lots of flash, and is most likely turned off because it uses too many resources contributing to the already sluggish OS's lag. I thought the GS3 was a good phone, the GS4 not so much, kind of like a GS 3.1. Samsung and Apple make obnoxious amounts of money out of these people that must have the next greatest thing, and there are many of them. Maybe I'm being old school, but I don't see the need to rush out the door unless what I have is already showing its age and like I mentioned above, the GS3 is still very much current tech.
