Although Samsung has not officially told us why this is the case, the fix for this problem is simple.
If you do not have sufficient space on this phone, you will not be able to move your files from this phone to a new one. It is with the old phone, also known as the source phone. However, the issue does not lie with the new device. This may be confusing at first because you may have plenty of space on your destination phone, as it is likely to be a new phone. When you are using the Samsung Smart Switch feature to move files from one phone to another, you may face the issue of the application saying there is not enough space for the migration to occur.
