So I'm going to update my review I have managed to get this device to work with my Android phone but only by deleting the SanDisk app which the instructions recommend one use, after installing from the app store. I got constant error messages using this app the device got for really hot using this app most of the transfers failed using the app. Subsequently after DELETING THE APP I've been able to go into settings on my phone and utilise the USB option within the settings and copy data and files back and forth successfully without any problems errors or heating of this device so I have been able to use it with my phone and then transfer data to my PC. still with Android devices phones it possibly require some technical skill in order to be able to do this. --------- So far this product has been slightly better than useless. You're taking a large risk using this device with an Android phone if you think that is going to work as is claimed... And error messages from failed transfers prompting a request to send via email the log get.. The following message..." Delivery incomplete There was a temporary problem delivering your message to firstname.lastname@example.org. Gmail will retry for 45 more hours. You'll be notified if the delivery fails permanently."
