I currently own a Samsung J3 emerge with Android version 6.0.1 (Marshmallow). However, I cannot format my AD card as Internal as I do not have that option. I cam only format it as portable. What must I do?
Well the device may have option of using SD CARD as internal storage if it is marshmallow or up ,as it was a feature introduced in ANDROID 6.0
Usually it can be found by Method 1 SETTINGS<
Method 2 If Sd card is not inserted then insert it and a notification will appear in notification panel that you want to SETUP or EJECT Select SET UP and it will present you option to format as internal storage Select it and you will get it done (if sd card was inserted beforehand only just eject it and reinsert to get that notification )
Method 3. #root required # Download an app Root Essential Grant Root Access Go to storage tab Select Adoptable storage Proceed with instructions And Now SD card will be used as internal storage
