Power button broken

Of course not all depends on the Samsung approach, but frighteningly close.
The processor is slow, so that the images not run smoothly. Properly disturbing is not that.
The functions of Android phones are otherwise a Samsung par.
Also from the housing it does not fit in the fit of the S4 Cases, so you can not rely on the wide range of cases. A screen protector is included, however.
Purchase was crucial: It only costs a fraction of the S4, so that when a fall is not much broken.

The power button is broken.
The seller I can not reach for a warranty claim.
If you forget to charge the cell phone, it's definitely useless because it can not be turned on.
For about 7 months of use actually a disgustingly expensive device.
