I have a Samsung Galaxy S7 in which the connection for charging is broken, I always have to charge via such a "Fastcharge" charging station. I now want to buy a new cell phone and before that transfer all of my pictures (not exactly a little) to my laptop or save them on any page, but I don't know how because I can't connect my cell phone to the laptop via a cable.
Bluetooth dongle for the PC purchase (costs between 5-20 euro), then you can also save your pictures.
