SD Card unmounting A53 5G

[MathVDS]

I recently got myself a Samsung A53 5G.
But I am encountering the problem that the SD cards keeps losing "connection"
I used my Samsung Evo SD card that I got a few years back for my previous phone. (Galaxy A5) during a Samsung action.
The SD card works fine in my old phone. But in the A53 it keeps unmounting itself after a while.
(It is also not visible anymore in the storage settings).
The only option seems to be to restart the phone after which the SD card is available again.

The interval ratio seems to be rather random. (1-2days) and I can't seem to find a 'trigger'

I also did an unmount - mount cycle after a reboot and this runs normally but after a day, same problem.

I double checked that the SD card was fitted correctly (removed it and refitted it to be sure). But this didn't change a thing.

There seems to be more posts about this problem but there never seems to be a solution. From what I can see the Samsung SD card is just buggy af with a Samsung phone?

Yeah, I think so too. Still somewhat strange, but it works now. So I guess I found my solution! Thanks

Hi, Is it now working normally or is it disconnecting again?

No further problems and disconects since changing the SD card. My old phone is still using the old sd card without a problem, so I guess it was some incompatibel issue.

I have exactly the same problem.  It is exasperating!
