Samsung is dumb for removing the SD card from newer phones but having no way for the the app to read a backup that is transferred from old phone to computer to new phone. I tried using the app to transfer from a old device to new while I was sleep and it took over 10 hours and froze at 42%. I did a backup to my SD card on old phone, transfer to computer and transfer to new phone just to find there is no option for smart switch to read from the internal drive. Fix this app or give back SD cards.
