[S7- Solved] change screen and save data: Galaxy - Forum LesMobiles.com

Hello, My S7 had a very bad experience of a "screen on tile" fall. Now the screen is black, possibly with some color spots. If you call it it rings, when a message arrives it gives the alert. I went to a Samsung authorized repairer, but... the repair technician being absent, I only had one employee who was not in charge of it, but who otherwise was very kind. He told me that the screen had to be changed, but does not think that we can save the data because he says that he does not not see them by connecting it to his PC. The repairer in title not returning until August 20, I took back my mobile Do you think that it is indeed impossible to save my data by changing the screen?
