SD card not detected " " Incompatible format"

Hello,
I received my Samsung Galaxy S7 a month ago. A week later, I inserted a micro SD card, everything was fine. But for the past week, it's been weird. I've been getting notifications like "SD card removed," "incompatible format," etc.
At first, I thought I had inserted it incorrectly, but no...
It says "format error" so I reformat it, and then two days later it starts bugging again. I changed the SD card, and I got a SanDisk 4GB class 4 (yeah, not great), instead of an unknown brand.
I reformat it (exFAT, 32 bits).
But here too, I get messages like "SD card not detected" "incompatible format."
I also realize that sometimes it works, but when I charge my phone, it bugs out.
Also, the SD card works perfectly with my computer; I have no issues.
Thanks in advance for any help, and have a great day!
PS: With joy and good humor :)

Good evening,

Is it only a problem with the microSD card...??

I advise you to format it with the "SD card Formatter" utility and to format it in FAT 32... Not in exFAT 32 like Windows does..

Ok, thanks for this very quick response! In fact, my old Micro SD, I also formatted it in exFAT 32.

I will give it a try!
Have a good evening!

I did it and so far it's working. I will wait a few days to see if it doesn't happen again.

Thank you very much!

Finally, as soon as I plugged in my phone to charge, it started glitching again, and it does the same when I unplug it.
My phone comes from the United States, maybe there's a voltage issue that's blocking the SD card?

Still, it's more stable now; it ejects the card less often.

Hello,

What is the exact model of the smartphone?
Generation “gap” with the Nintendo?

There are several types and it’s not the same thing, some devices are not compatible with....

microSD
microSDHC
microSDXC

Did you program it?

Thank you for keeping me updated => “Still in a bind” “It’s resolved thanks to/ I found out I had to”
because I often have several steps and always a trick up my sleeve!!!

I looked, the smartphone reads everything (256GB max).

Before buying, I would test it with a micro SD card thanks to my knowledge (if you only have one, ask someone else then). It needs to be formatted or a copy of the content needs to be made, of course.

This prevents another disappointment if it's the smartphone's reader that is damaged...

I have this brand; they are everywhere, I have several SD cards from this brand ;)

Did you usually remove it to put it on the PC or another device?

(Regularly remove/reinsert the card into the smartphone's micro SD card reader)

I confirm you bought it in the USA!



=> Confirmation no problem ;) for me the reader is damaged...

It's up to you, you can test with a micro SD card that you buy or with a micro SD card from someone you know ;)
