Samsung galaxy s10 default save location. When selecting save file, music and sound can be heard. Even the save button and ? Can be seen. But the video is all black
In what country was that device sold to you? It might be an issue with the local environment of the device (Unlikely though...)
Do you load a save from the main menu ? Or from in game? (Or both)
Where did you save those save files in game?
Did you wait a little bit? (Might be just loading)
Do you have enough ram? (Might be too many open things at once)
I'm asking all of those questions, because I can't reproduce the issue myself...
