Can't copy past a picture from my PC to internal storage folder of iphone 6S
I have an iphone 6S+ and I can't copy/paste any picture (done with an iphone in the past) from my computer into the internal storage/DCIM/100APPLE.
It used to work perfectly in the past.
It's really stressfull, it looks lile everything is geting harder and harder
How can I do it like in the past ?
iPhone 6s Plus, iOS 9.1
