[WPCentral Question]

I take a lot of pictures with my IPhone, I upgrade to ios 7 at the same time as upgrading to windows 10 on my lenovo u430 laptop, I now cannot import pictures from cell phone to laptop The message on laptop in Lenovo photo share or in another apps for pictures says no new photos found, but the cell phone will display TRUST this computer, but only for a second or two even if you tap trust in this brief display you cannot import and the trust message disappears unless you tap try again on the laptop I have lost about 2 weeks now and looking for plain ez fix.I have imported 100s of pictures before these upgrades
