Samsung J3 - How to set SD Card aslot default storage?

[LOPEYBOI]

Hi,

I've put an SD card into my J3. Downloads keep trying to go to the phone which is now full. How can I set the SD Card as default storage? Also, how can I move music, videos and photos onto the SD Card please?

Thanks

1. Install and run External 2 Internal SD (Root) (the phone has to be rooted). That will swap internal and external storage.

2. Update to Marshmallow (at least) and format the SD card as adoptable storage. You'll lose "internal" and "external" and have just "storage". The phone will decide what goes where.

(Downloads and app installations should go to internal storage - it's how Android works. External storage - SD cards - was designed to keep media files.)

3. Use an app like Total Commander to copy files in internal storage, go to the SD card and paste the file (one file at a time).

Any of the 3 ways will work, depending on what you want to end up with. (With #2, you can't move the SD card to a computer and "see" the files - the format is completely different than any computer can read.).

You do not have to root your phone. Check out the instructions here: https://www.xda-developers.com/enable-adoptable-storage-for-galaxy-s7-and-s7-edge/

This says for S7, but I have tried it on the J3 and it works as advertised.
