@MojangSupport After choosing Choose New Skin in Minecraft, the screen becomes dark and there is no photo selection, what should I do?

Try fully logging out and back in, as well as restarting your device. Let us know what device and Edition you're playing and if this issue persists. ^AM

No, it’s not. This system is Android, but some functions have been castrated. I think it may be because of this that Minecraft cannot find the program to call. Do you have some methods of how to import files directly without using the APP?
