I have an iPhone 6 Plus and a laptop from Sony. I always upload my pictures from my iPhone to my laptop using the charging cable. That always worked, I never had any problems with it, but now I always get a notification that there are problems with the connection. In the further information you have to allow the computer to access the iPhone, I always did and also worked and the pictures must not be on the iCloud, which they are not. Despite everything, this message always comes.
I don't know what to do next I've tried several charging cables but always the original from Apple. I also have enough memory on my laptop.
Install the latest iTunes version on Windows 10. Then it should work. IPhones and iPads are unfortunately gagged on iTunes.
