Many thanks, J.A. Taking a photo did the trick, thank you. But once the photo had been down loaded the phone didn't show again in Explorer. Still, I can work with that. iTunes is working fine. Thanks again for your help.
I had this same problem with my Samsung Galaxy III phone,using then Win7Pro Also when i had Win8.1 but after installing Win10 i can now connect my new iPhone6 also the old Samsung phone to my computer.
I would really advise getting Win10. It might not be the total cure but it's a step i feel in the right direction.
