*** APPLE???? System using 12 of the 16Gb of my iPhone!!

So, I don’t have much apps and while I have some photos, I don’t think it’s that many compared to some people. And I had noticed my phone was always out of memory and now that I’ve updated to iOS 11 it’s even worse. But with the new version, I can perfectly see “System” occupying, at this moment, 12,14Gb. I mean, is this for real?? I have a 16Gb phone and you’re taking away almost it’s all memory for the system?? Where am I supposed to store my stuff at? Where am I supposed to install my apps at? I mean, seriously Apple, this is ****** up.

I want more memory!! I bought my phone for my stuff not for yours. Fix this!!
