First GS4 Review Is Out - Phone Arena 9.3/10

It would have been nice if Samsung had improved the camera only making pictures bigger doesn't mean improved performance, haven't seen any good reviews, most editors are saying low light performance is not good. Build quality is poor for a phone at this price point, will have to see in person, but it definitely seems better that that of SGS3.

Everyone who used it said build quality makes it feel better than the s3, and most are saying the camera is pretty good( except as you said in low light)
 
In that review video, he slides out a sidebar from the home screen at around 1:20 mark. Is that most recently used apps or is that like a quick launch bar where you can put whatever apps you want in there?

I am coming from Galaxy SII with ICS, so...

I think that's for multi window
