So I got a texture pack on mcpedl. Downloaded it. Choose it as the texture pack on Minecraft.
Then the skin changer appeared on the top of the open sequence with the help thing be side it but the Minecraft logo was upside down at the bottom of the screen and then when I pressed any button like Play it takes me to a blank gray screen and I can't get out of it unless I press the home button. And nothing I try would stop the bug.
