iXpand Fails to sync with camera roll

Agree with the above. Struggling to download photos from my iphone 5S. Almost all photos that I select ‘Failed’ to transfer. Randomly 1-2 would transfer. Both the IOS & ixpand software are latest.

My Instagram 850 odd photos transferred without any hastle though. Went to my local vendor in Dubai (E-Maxx) . Told them the problem. They just replaced the item. But facing the same issue again.

Hence iám here to find a solution. 

As somebody mentioned that the phone should have enough memory (similar to RAM) to be able to transfer photos. So i deleted 300 odd photos from the total 1800 (16 GB phone). But that defeats the purpose of this product. We have bought this product to be able to transfer ''ALL"" photos at one go.Without having to delete 10-20% photos …!!!

Hoping a technical expert from SanDisk can assist.
