I just upgraded my Asus Zenfone 2 Laser to Marshmallow 6.0. Then I cant transfer my apps to the SD card. I understand that Marshmallow only allow internal storage. I already format my SD card but still can't format it as an INTERNAL STORAGE as I don't have that option in my setting. I only have EJECT & FORMAT option. But if I choose FORMAT, it will only format my SD Card. Not format my SD Card to internal storage.
