Can anyone help me understand this system ui/micro SD problem

[Justin Bottrell]

At first i thought it was just my sd card dying but then i noticed that. It performs fine all day every day, that is untill approximately 2:30 am when i get a notification from system ui that says "cant write to sd card your sd card isnt working correctly and has been set to read only to prevent data loss. Backing up the data in your sd card is recommended." As i stated i didnt think anything odd untill i noticed that it only happens at about the same time everyday for about 2 weeks now. I have a galaxy a50 was TracFone but i had it unlocked and put it onto Verizon. I have removed apps that are not my regulars. I have usually been able to figure stuff like this out since the release of the s4 when i started to learn about Androids and what not. But this has me baffled

Welcome to Android Central! Can you test another SD card? That can help figure out if the issue is with that specific SD card or with the system.

and, as we caution in EVERY thread about SD cards - unless you bought a reputable brand from a reputable seller it's entirely possible you got a card that isn't as advertised.

Agree with what others mentioned.

Agreed with the others as possibilities.

Is this a new SD card? Or one you've had for a while and only recently started doing this?

Where was the card purchased and what's the brand?

Sounds like something is trying to back up to your SD card at a specific time. I would try a different card.
