A good decision

+ Super compact size (had S2, S3, S4 ...)
+ Best acoustics, no difference from the point S4 fixed
+ Amoled display - black is black
+ Resolution: better than before buy feared not high resolution, but sharp and sufficient for the size
+ Processor: even better than expected. The part is afloat - naturally within its means.
+ Good workmanship: plastic, plastic, plastic. Who buys the Samsung knows beforehand. Nevertheless, it touches his "good".
+ Battery life: OK. Keeps well the day by (once had a HTC One Mini - term catastrophic)

o Camera: Nuja, no comparison to the great, but still OK.

- Built vibration motor sounds like a cordless drill which starts slowly.
- The notification LED I really miss - but the free app "NoLED" creates alternative remedy.

The battery cover of the device is in imitation leather optics (similar to that of the S5). Looks really great and feels good and crisp and makes a stable, knarzfreien impression.

I highly recommend this device for those looking for a compact device with a super performance and can live with a not so great camera and not quad-core processor.

For the money, my best decision.
