I can't access to the minecraftpe folder

I just try to access to the "minecraftpe" folder to disable vsync inside the options.txt file but the folder don't exist inside the android storage ( Android/data/com.mojang.minecraftpe/files/games/com.mojang ), the resources packs folder is there, the skins packs too but the minecraftpe folder is missing, I already allow the game to access to the external storage, but then I access to the root folder of minecraft, inside the system files ( data/data/com.mojang.minecraftpe/files/games/com.mojang ) and the minecraftpe folder is there, although I already changed the game settings to external memory, I accessed the system memory through an Android emulator on my PC, but the point is that I can't access options.txt through my phone

UPDATE

If I copy the "minecraftpe" folder from the System/Data to the Android/Data folder the game finally recognize the folder but the point of this post is that the game can't create the folder automatically into external storage
