iphone 6s wont connect to itunes/PC
I have had an iphone 6s+ since february, and recently went to connect it to itunes to back up and transfer music to phone, but when I plug it in, the phone and the PC makes a sound, itunes opens, but the phone does not show up in itunes. The dialog on the phone shows the Trust/Dont Trust box, and I tap trust, and nothing happens. The phone also does not show up in Explorer. The phone also shows as "charging"
I have tried all the settings within the phone, as well as the PC (deleted some folder in itunes that another article said to try), that did not work, the folder also shows up again after restarts. I am at a loss, as doing a factory reset is a bit out of the question having not backed up the phone yet.
Anyone here have any other options or information, seen this problem? Any guidance would be of great help. Thank you!
iPhone 6s Plus, iOS 9.3.1, Windows 10
