Don't know if this will help your situation but I use PhotoTransferApp to transfer from Samsung S4 phone and PC and vice versa. It's not free - £1.29 - and needs your wifi to be active and both PC and tablet to be on the same wifi but it works like a dream for me. As well as downloading the App to your tablet you have to download a similar named program to your PC but the App gives you all the details. Good luck!
