All the controls are perfectly zugägnglich and the Orientiereung on mobile now falls more easily.
A small drawback which personally is not a problem for me: The opening for the SIM / SD card is face down. This can be seen but already on the pictures are shown.
I am very pleased with this envelope.
It lies well in the hand, looks simple and gives a sense of security.
For enclosed screen protector I can not say anything. This is not in use with me.
