Well, it is going to depend on what you are downloading and how. If you are wanting to download apps and run them from the SD card, that takes a bit of changes (which I will include in this post) as well as your manufacturer having not restricted this option on that phone. Sadly, it happens.
Now if you are only trying to download say music, photos, files, etc., and not apps, directly to the card, well then you would change the settings in the individual apps you are doing the downloading through. Say "Chrome" for example. You would have to change the download location settings within the "Chrome" app to make it save to the card.
How to turn external SD card into internal storage on "Marshmallow".
NOTE: Please be sure you start with a blank SD card. It needs to be blank because when the card is converted to "Internal" storage, it will be formatted (wiped) and encoded (making the cards data only readable by that device).
1. Go to device “Settings”, then select “Storage”.
2. Select your "SD Card", then tap the “three-dot menu“ (top-right), now select “Settings” from in there.
3. Now select “Format as internal”, and then “Erase & Format”.
4. Your SD Card will now be formatted as internal storage.
5. Reboot your phone.
Hi webworkings,
I have LG K8 and have tried to follow your instructions above, but when I get to point number 3 the options given are ''Eject'' or ''Format'', it doesn't give me the option to ''Format as internal'', any suggestions?
