So cover for an S4 it is absolutely nerve-wracking !!
The S4 has a so-called. SmartView function.
This is designed for the special cases with the viewing window.
The function is controlled by a magnet and can not be disabled.
Problem now is this envelope also has a magnetic,
Depending on the attitude activated repeatedly that black screen where you can do anything,
read except the time and date.
Who does not know angry probably still on the great phone,
simply going from time to time.
But is actually on the magnet casing.
As I said, the shell itself is fine.
However, I would find a good note!
For me, the envelope is therefore useless. Can do anything with it when the phone is black from time to time
or the SmartView terms.
