how to store on my SD card

Solution
Well that depends. Are you trying to just move photos and videos (as well as apps that are actually movable) to the SD Card? Or are you trying to set it up to store anything/everything on the SD Card, including apps, games, download directly to, etc.

If it is the first one, you just have to go into individual apps to have them save to the card (like photo programs) and also set the camera to save to the card rather than the device. For moving 'movable' apps, you go into "Settings" then "Apps" and scroll over to find the list that says "All". From here tap individual apps to see if they are movable. If they are they will have a "Move to SD card" button.

Now, if you are wanting to move all stuff there, or download direct to a SD card...

Now, if you are wanting to move all stuff there, or download direct to a SD card, that is only possible on Android phones running "Marshmallow", and then only if the manufacturer hasn't restricted that option. If your phone is running anything other than "Marshmallow" then you would need to see if you can upgrade to it, otherwise this would not be possible. Also, even having "Marshmallow" doesn't guaranty it will work, as some companies have decided to restrict that option on their phones. Why, I can't tell say, but they have.

The only way to find out, is to try it on the phone. Again, "Marshmallow" OS is required. Then take a blank SD card and insert it into the phone. If the card already has anything on it, that data will be erased, so make sure it is blank or nothing you want to keep.

How to turn external SD card into internal storage on Marshmallow.

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.

NOTE: If you don't reboot the phone, many things may not work correctly, so make sure you do.

Also, once the card is set as "Internal" it will not be readable by other devices. It is now set to work on only that phone. So any information on the SD card cannot will not be accessible were you to try placing the card in a different device.
