Because of better performance data compared to the S5 mini (with identical price) I had initially decided on a S4. But the size was found to be unpleasant, although it is not even is a centimeter longer. At first I thought, this is a matter of habit. But the habituation effect does not set in. Therefore, the Exchange for S5 mini and was a good decision. Also, the Home button is the S5 mini intuitive with your thumb to find than the S4. This has probably to do with the different distance from the outer edge devices.
From an S2 with Cyanogemnmod 11 coming, the conversion was completed on the Samsung Use Röber surface of S5 Mini after a day. But the additional features Samsung (AirView, heart rate monitor, fingerprint scanner, etc.) I think after a week use rather for game Erreien without everyday utility. The accessibility of many settings is cumbersome. Once there is a stable CM for the S5 mini, I will I change the Android version well again. One of many examples of the cumbersome user interface is the circuit of the GPS button in the Quick Settings: who is with Samsung's Touch Wiz on or off, at which either energy-saving GPS (only radio without real GPS) means or full GPS. If CM can be changed at the Schnelleinstelungen between sleep mode and real GPS. The many additional features of Samsung with dubious benefit are clearly at the expense of ease of use.
To all critics of the plastic case: With a lightweight device rather than a heavy equipment. In a protective case, the difference can hardly see anyway. After 3 years of use of the S2 I think plastic housing for durable. Anyway, my previous HTC device did not have a metal within a few months the first unsightly scratches and S2 after three years.
Conclusion for S5 mini: hardware top, software adaptation flop.
Important to know before buying: The S5 mini has no FM radio more. I think this is a small, albeit verschmerzbaren disadvantage. Because the supply of mobile data radio is traveling always an imposition; even with two SIM cards from various providers (Vodafone and Telekom).
