=== Linking your internal apps to External SD card ===

There is another option to use your external card as storage for your apps. Advantages to using external card as internal storage is, you can still use your external sd card at card readers; you can move your apps back to internal storage if you want to replace the card; if you don't link system apps from internal storage to external card; you will be safe even if the external card gets corrupted. Also you can continue using RetroidOS with this option if you choose to. Lastly, you won't have any trouble with OTA updates.

To be able to do this first you need ROOT. Refer to the rooting section under Firmwares on this wiki. Afterwards, you will need a program as Apps2SD. Download it from Google Playstore. Open it, you will need to use "Partition Tool" from the first main menu. WARNING: This will delete your whole card and you should do a backup before doing that. You will have 3 options at Partition Tool, first one is for Rom storage; make it as FAT32 format, second one is for moving the apps; make it an "ext4" and the third one is for "swap" that is supposed to add more RAM for the system to use. Resize the partitions to your liking and hit "yes".

Device will reboot at that point. Open Apps2SD,  click "Link Apps to SD card"; it will ask you to create mount script. Choose ext4 and from below, tick the box to the left of "Advanced". It will say "Success!" on this point and apps will show up. Just choose the app you want to carry to external sd card and click Link from bottom right and it is done.
