But, in that sense, it makes the Nexus 4 and One look like supercomputers.
Apart from various deal breaker issues with those phones like removable batteries and SD card slots, no, not really. I prefer to state it as the lag issue being vastly overstated here and turned into a blown-out-of-proportion bogeyman that has the effect of completely misleading as to how fast this phone actually is at performing its various tasks.When, for instance, I pull up my ebook directory with File Manager on my card with over 2000 ebooks, it does so as fast--or faster!--than my desktop computer, an XPS from Dell. It outpaces my old HTC Sensation by a factor a zillion to one. (Yes, I know that's not scientific,
but ...) I saw a post above about going back to the home screen, etc. Got my phone out. Went to the 3rd alternate home screen. Back to the 1st. Instant. Not even a hint. Opened up Cool Reader. Instant (although that's a different type of issue). Hit the home button. Cool Reader dissolves. Whoosh. Exactly as it should be. Pulled up Pocket. Instant splash. Back to home screen. Dissolves. Whoosh. Opened Evernote. Popped up instantly. Pushed the home screen. Dissolves immediately. Whoosh.
Even assuming arguendo some significant lag issue--I've seen nothing that would have even made me think about it until I read threads on this forum, and I'll bet the typical user upgrading and starting afresh sees nothing amiss and couldn't care less--there are also other important speed issues where this excels. Controlled tests demonstrate how snappy this phone is, using the latest updates, with apples-to-apples comparisons. PC Mag, May 2013:
"Sprint's Galaxy S 4 has the same 1.9Ghz Qualcomm Snapdragon 600 processor as T-Mobile's, but I found that this unit benchmarked slightly faster, possibly because it's running fewer background services like T-Mobile's Wi-Fi calling system. In any case, it's the fastest Android phone I've seen yet."
The t-mobile review, btw, which I use, a month earlier said:
The 1.9GHz Snapdragon torched the processor-dependent Antutu benchmark, but it also did unusually well on Basemark OS, which launches real applications, and on the GLBenchmark graphics benchmark. Even pushing all the pixels on a 1080p screen, this is the fastest Android phone available. I topped off performance testing with the hideously heavy Need for Speed: Most Wanted game, which ran like butter on the S 4. Spectacular speed results carried over to network testing, too."
One thing between those two reviews that we might note is that not everyone may be talking about the same thing.
You said in one post "To be honest, I haven't used the S4 much; only about an hour." I've used it a lot with a lot of apps that make my Transformer tablet and my former HTC phone choke or slow to a crawl. I'm not a gamer. Otherwise, I am a pretty heavy user and am on it constantly. The S4 zips along and generally seems lightning fast. If there are complaints to be made with this phone, speed is not fairly put as one of them.
