Hi Guys! With 200 reviews the S4 there is not much to write. But: "Smart" is at these telephone sets nothing, absolutely nothing. Example: The S2 / S3 can not count - Samsung calculator (which as a "Samrtphone" is yes, a computer). eg 100-50% = 99.5? The S4 can do better, 100-50% = 50th I was overwhelmed, madness, a computer that can be expected. Can expect the S4 even with MMS (finally). In the S3 even 1kb files are automatically compressed. +/- 600 for a radio + Google operating system, which only in version 4.2.2, the MMS correctly counted ...!?
