On technical details Much has been written, so I can save the general data and confine myself here to the changeover reasons or personal experiences.
For me, handsets are still easy to operate with a phone with a display size from 4.3 to 4.5 inches, so I was looking for mainly a mobile phone with the latest features in this size.
Here came to me after the reviews, the S4 mini by price and features her most in question.
I have wondered about the fact that Samsung has the S4 mini donated only 8GB of memory, even the S2 had 16GB on board.
Battery life and handling was okay, also display.
But what was a KO criterion for me, the bad camera S4 mini. Although reviews praising the camera, for me this is not to be used.
The images are milky, noisy and colorless. I made recordings parallel to the S2 and S4 mini bright light outside.
The S2 does here considerably sharper, more vibrant images. Both phones have been set here at 8 MP and otherwise identical settings.
The DPI number when S2 was 96dpi, the S4 mini only 72 dpi, with the same number of pixels (3264x2448).
Both Agents Concrete without flash in automatic mode.
I could just make an effort reasonably usable images with the S4 mini erzeug, even if that came not serve up some quality of S2.
At first I thought I might have overlooked a film on the camera lens, but was not. Also repeatedly cleaned and checked.
Too bad that Samsung has so saving mini at S4 on the camera.
Handy therefore went back.
