Fix for who want to use the folder "external_sd" in the internal storage of the mobile phone again instead of folder EMMC in the root of your device to acces your external sd card.
download Terminal Emulator from google play..
(press enter after each line):
mount -o bind /emmc /mnt/sdcard/external_sd/ (enter)
caution ! you need to put space after these sentences
your external Sd card is now linked in a folder in your internal storage of your device again under external_sd
