Have had numerous Samsung phones and have used this App successfully when switching devices. However, when I used it most recently, I trusted it to do what it's supposed to do and let it do it's thing, only to find out later that most of my photos did not switch to the new phone and one photo in particular, which unfortunately is not saved in the cloud and means a lot to me is now gone forever. Therefore I have nothing but contempt for this App. 2022 2 years later and still doesn't work!!!!
