You can do almost anything with your phone, only the finger print sensor doesn’t work.
This is a problem with the IPhone 7 and 8, because the home button is not a button, but just a finger print sensor.
But we have a solution: The home button has to be placed on the homescreen.
How does it work? > apple settings > general > accessibility > assistive touch > “turn on”
Now the home button appears on the display and the phone can be used without the physical home button inside the pOcpac.

The pOcpac is not 100% waterproof, so you should not keep it underwater or expose it to heavy rain for long periods of time.

Your phone of course! And usually: Money and one or two individual keys. Because of the separation layer, your phone is more protected to scratches.
