sd card shows as read. yet device storage full

[AC Question]

As above. Downloading a film currently and notification that device storage is full comes up. However when I go onto settings and storage it shows the sd card as read and with full space remaining.

Samsung A5
32 gb sd card

Hi, the file you are downloading is automatically being saved to your phones internal storage, not the SD card = this is why you are getting this message.

Also, from his wording, the card may be set to read only. Just thought.
