As described above, the USB port is for battery charging or for connecting to a PC not accessible when the phone is clicked in Case. It sits fairly firmly in the shell (which in and of itself is positive), one needs to have a means to get the phone out of there. And this must be so often. The processing itself I find very good, the shell does not contribute to much the device is firmly in it. But the upper clip that sits directly on the flap for the USB port and blocked this is a bad design. This flip-case I can not recommend therefore unfortunately. For the processing itself, I would give it 5 stars, but so ...
I have now found me another flip-case, where I can make the phone even during loading and / or when connected to the PC. Here's how it too!
