@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?

Unfortunately, we do not and our tech support is very limited in these instances :( ^TK

Can Mojang provide how to change directly from the configuration file?
