Repeated SD card notification.

[RhodaCee]

Keep getting message saying SD card is read only and nothing can be saved on it. Removed images, not many then formatted it.

Have Samsung A20e.

Notification came back. Now cannot format it, only unmount. 

Any help/ suggestions pls

Have you tried formatting on a PC ?

Thanks. Will try. Didn't know about via computer.

Most often this indicates the corruption of the card itself. When Android encounters a read/write error on the card, it will re-mount it as read only, to avoid data loss by causing more damage.

Don't store important data on that card... and if you get this error even after formatting on a PC, throw the card out, and just get a new one.

If this card was in a previous Samsung phone. What are the likely causes of corruption. Had no problems previously.
