SD Card Can't write

[usereLCftTnLl4]

I am having the same problem, and it recurs. The phone is a year old, and clearly it's a software update problem. I am far from amused, as it lost pictures I took at my son's wedding, for crying out loud. If they can't fix the software, I am going to take this thread to the seller and demand a refund. I have Samsung products all through my house, but I am totally disgusted at the lack of clear response to a software problem that is clearly widespread (multiple Galaxy models on multiple threads) and of fairly long duration. There needs to be a software update that fixes the problem NOW.

I have the same problem with my Note 10+ after the recent update. Come on Samsung, get a fix out there.

Same problem for me on my A70 since Android 10 update.

A new SD card and a factory reset haven't fixed this issue.

Was thinking intially it was a hardware problem but after factory reset fixed it for a while and reading this thread it's apparent that it's a software bug

I literally just got this message TODAY! Was listening to music on my S10+ through Tidal and this message... which is weird cause I've had this SD card through 3 different devices with no problem. Please fix this Samsung!

I had this problem as well when I updated my software. I was about to copy everything that is on my SD card to my laptop, so I could format my SD card. That is how I got around this before. But this time, I had a notification come up saying that I needed to update my time zones. Maybe because your phone had an update, it messes up the times and dates on your phone? But I am not entirely sure. So, if this happens again, make sure to save anything you want to keep unto another device and wait a little until 'update your time zones' notification comes up. If that fails, I suggest formatting your SD card. But make sure you save anything you want to keep on another device 

I hope this helped you in some way, and I wish you the best of luck in the next software update

Had the same problem and fixed it.
1. Unmount and backup on your PC/Laptop

2. Reinsert SD card to phone/tablet

3. From Settings navigate to Storage (on my device its located under Device care

4. Navigate to SD card and format

Bingo! Should work

I am getting the same message plus I have over 13k pictures that I can no longer see. Has Samsung found a solution to this because I've tried all the above suggestions and nothing has worked

Obviously, there is some thing wrong with the majority of the Samsung Phones. I have the same problem on my Note 10+ withe two different SD cards, my original 128GB  and a new 256GB. Both were reformatted. 

A shame.

Hi, I purchased two Samsung A21s in August for myself and my wife. Sd cards (SanDisk) from the old phones used which I reformatted before inserting. Worked fine for approx a month and then got the message 'can't write to sd card message', lost access to a number of photos which was annoying. The same issue occurred with my wife's phone at the same time. I reformatted the sd cards which solved the problem for a short while then it happened again in both phones. It is clear to me that it is an operating system issue. It has put me off buying a Samsung in the future. The reformatting solution mentioned works but only for a short while.
