itunes not detecting iphone 12
Hey guys, just got my iphone 12 (previous phone was iphone 8), but itunes is not detecting the iphone 12. I'm trying to transfer all the data, texts etc from the iphone 8 to 12 but whenever I connect the 12 to my windows PC it just doesn't detect in itunes. My PC detects it - I can see it in my files and it is in device manager, but itunes just doesn't recognise it. itunes is up to date with the latest version and it still detects my iphone 8 when I plug that in. I tried power cycling the phone and even uninstalling/re-installing itunes but no luck .. tried it in different USB ports as well which is the only thing which makes a slight difference. In one USB port its like it detects it for a brief moment then its gone, all other ports it never appears in itunes. But all my USB ports work perfectly fine with all other devices.
So I was hoping people may have any advice? Cheers :)
iPhone 12, iOS 14
