Purchased a S10e a week ago, have now found two problems,
1) you can not save your photos to a micro S/D card if you install one and then Sync the photos to Samsung Cloud. They will not sync unless you saved your pictures taken to the phones internal drive.
2) If you do save your pictures to the phones intal drive and they are then Sync'd to the cloud, if you then delete from the cloud they are sometimes deleted from the phone as well. Samsung are aware of this and apparently working to resolve this problem.
It would be nice to be able to save to a S/D card installed in the phone and to be able to Sunc to the cloud, hope they look at this as well.
In the meantime will use Google picture that will Sync to Google pictures.
